购买液晶显示器时要注意陷阱
挑选液晶显示器
怎么挑选液晶显示器漆，但液晶显示器的"点缺陷"却是消费者人为无法修复的。
而如果你在选购液晶显示器时不加注意，碰上某个或几个坏点恰恰都在液晶屏的中央的话，那么就更令人懊恼了。
液晶屏的"点缺陷"不光是液晶显示器所独有，有液晶显示屏的地方就有坏点，这已成为全球对液晶显示器投诉最高的问题。
比如彩屏手机，在购买手机时，商家通常也会将机身默认的墙纸图案以黑色或艳丽色为主，让"坏点"隐藏其中，让你难以察觉到。
而在实际使用中就会因更换墙纸或屏幕背景而发现。
手机屏幕不超过3个坏点就属于A级，商家可不更换，所以选购时就需你多注意这方面的情况，以便能提早预防。
同样，在PSP 热卖的背后也隐藏着液晶屏的问题，目前对PSP质量问题的投诉最多的也是PSP的屏幕坏点，据统计，PSP 首批出货的坏点率达到了三分之一。
同样问题也出现在任天堂NDS主机中，其部分产品亦出现普遍性的屏幕坏点。
总之，无论是液晶显示器还是液晶电视，采用液晶屏的所有数码设备，如手机、PDA、掌上游戏机、DC、DV等等，都可能出现液晶坏点问题，大家在购买这类产品前都需对这问题先打起十二分的精神，并掌握一些必要的液晶"点缺陷"知识以备急需。
二、"点缺陷"的概念和成因什么是"点缺陷"？大家知道，液晶屏主要由滤光片、偏光板、玻璃、冷阴极荧光灯组合而成，"点缺陷"就是液晶显示板上不可修复的像素，其除了人为损坏之外，多是在生产过程中由于亮斑部位的屏幕内部反射板受到外力压迫或者受热产生轻微变形所致产生的。
液晶面板由众多的显示点组成，靠每个显示点上的液晶材料在电信号控制下改变光的折射率成像的。
比如标准分辨率为1024X768分辨率的液晶面板，一个液晶板就有786432个显示点（像素），在大小为0.099mm每个液晶点背后都对应有三个晶体管，并又分别对应着红、绿、蓝滤光片，在每个液晶像素背后还集成一个单独驱动它的微型驱动管，在这235万个液晶像素中其中任何一个晶体管出现毛病都会使这个像素成为一个坏点或亮点。
LCD液晶显示器选购技巧
LCD液晶显示器选购技巧2007年11月08日星期四上午09:06睁一只眼挑坏点液晶显示器是利用液晶的物理特性来进行显示的，即通电时液晶排列有序，光线容易通过；不通电时液晶排列混乱，光线很难通过。
就构造而言，液晶显示板包含了两片相当薄的无钠玻璃材质，中间夹着一层液晶。
我们都知道玻璃是非常脆弱、很容易破碎的，再加上液晶显示器的每一个像素都十分细小，所以在生产和运输中常常会造成个别的像素坏掉的现象，俗称“坏点”。
这种“坏点”是无法维修的，只有更换整个显示屏，而更换液晶屏的价格往往十分昂贵。
所以在选购液晶显示器时一定要看清楚是否有坏点出现。
目前普遍可以接受的标准是亮点要控制在三个以内且最好不要出现在屏幕中央。
在观察亮点及死点（不发光的点）时，您可以分别将桌面背景调成纯白、纯黑色观察。
闭一只眼看像素间距点距对于CRT显示器来说是至关重要的一个性能参数，然而对于LCD来说,相对应的像素间距却显得没有那么重要。
由于LCD显示器的像素数量是固定的,因此在尺寸与分辨率相同的情况下，所有产品的像素间距都应该是相等的。
目前38.1cm（15英寸儿CD显示器的像素间距一般为0.297mm某些厂商标示为0.30mm）, 43.2cm（17英寸儿CD显示器的像素间距一般为0.264mm某些厂商标示为0.26mm）。
因而人们在描述LCD产品时并不需要像描述CRT显示器那样，再三强调该显示器的点距指标是多少。
闭一只眼看分辨率不论是购买LCD显示器还是CRT显示器，分辨率都是购买者参考的一个重要参数。
但与CRT显示器不同的是, LCD所支持的显示模式不像CRT显示器那么多,而且它是由制造商预先设定好的，一般不能任意调整。
LCD只支持所谓的真实分辨率，相当于一般CRT显示器的最高分辨率，因为LCD只有在真实分辨率下才能呈现最佳的影像效果，这点与CRT显示器大相径庭。
目前，LCD的分辨率一般只有800X 600的SVGA显示模式、1024X 768的XGA显示模式以及1280X1024（43.2cm 以上产品）的高分辨率模式。
购买液晶显示器时需要注意的陷阱
购买液晶显示器时需要注意的陷阱购买液晶显示器时需要注意的陷阱● 液晶显示器型号繁多目前，很多厂商都推出了各自的液晶显示器产品，主流的液晶显示器品牌就有六到七个，并且如三星和LG等大品牌的产品线都非常丰富，而每一款液晶显示器都有唯一的型号，因此要记住每一款液晶显示器的型号、并了解它的性能参数是一件非常不容易的事情，消费者在选购时也会感到非常困扰。
生产液晶显示器的厂商不仅仅只有上面这12家对同一个品牌的液晶显示器而言，有两款或者是多款液晶显示器的型号都非常接近，不过两者在性能参数方面有着较大的区别。
如这两款或几款显示器的屏幕尺寸大小不同，或者是接口的配备不同等等，而这些区别往往会造成这些产品的价格也会有较大的区别。
● 一个字真的能骗你200元？LG L222WT和L225WT之间只差一个字符，但价格相差了200元很多人认为，型号比较相似的.液晶显示器，功能应该比较相近，因此价格也非常接近，即使被一些不发商贩“忽悠”了，损失也不会太大。
但事实上并非如此。
如LG的一款21.6英寸宽屏液晶L222WT 和22宽屏L225WT，这两款液晶不论在外观、性能参数还是在接口配备上都完全相同，两者虽然在屏幕尺寸上仅仅只有0.4英寸的差距，但价格方面却有200元的差价。
一些不法商贩会将这些21.6宽屏当作22宽屏推荐给消费者，从中赚取较大的利润。
而对型号不是很熟悉的消费者，则会很容易上当，为此多支付200元。
·三星943NW、943BWX、953BW三款19宽屏你能区分出来吗？类似产品市场上还有很多，如三星的943NW、943BWX、953BW三款液晶均为19宽屏液晶（943NW只配单接口、943BWX 钢琴漆/双接口、953BW双接口/钢琴漆/2ms），但对于普通消费者来说你能分清3款产品到底有何区别吗？如果分辨不出来的话很容易被奸商利用，最终受害的还是自己。
面对如此繁多的型号，怎样才能避免掉入奸商的陷阱呢？● 如何避免掉入型号陷阱？各大厂商每年都会发布大量新品，如三星和LG都在今年年初推出了共30多款新品，它们在型号的命名方面都进行了更新。

购买电脑显示器时需要注意的方面
1.温度显示器的适应温度，CRT在10～35℃，液晶显示器在0～40℃(具体产品参照其使用说明书)。
环境温度过低时，CRT内部的萌罩板受冷变形而使屏幕出现不规则色块或偏转电路的形变，造成磁场移动而出现模糊或拖尾现象。
另外，每一种电子元件都有它的工作环境参数。
当环境温度过低时，也可能出现图像抖动、变形等故障。
奇丽CMV-1502液晶显示器的工作环境温度在5～35℃，如果工作环境的温度低于5℃时，将无任何显示，常常被误认为显示器故障。
特别提醒：当一台显示器刚从气温低于0℃的室外带入室内时，一定不要马上加电。
需要等1个小时或更长时间，使显示器的温度和室内温度相同时再加电，以防止由于马上加电引起显像管炸裂。
环境温度过高时，显示器自身电路产生的.高温不容易发散出去，易造成散热不良，出现电路元件热击穿而引起显示器损坏。
2.湿度显示器的正常工作湿度为30%～80%。
湿度过大，易造成高压放电而损坏FBT或其他元件。
同时，显示器的电路元件在潮湿的环境中也容易损坏或漏电。
如果产生结露现象，水珠会引起电路短路，造成更大的损坏。
湿度过于干燥时，容易产生静电，造成电击现象，人体受伤或电路损坏。
3.灰尘显示器内部的阳极高压在20kV～30kV，极易吸引空气中的尘埃。
当显示器放置在灰尘或粉尘大的环境中时，高压吸附的灰尘容易积聚在电路板上，造成显示器电路元器件散热不良而损坏，也可能因灰尘吸收空气中的水分而引起电路元器件变值或短路而造成故障。
同时，CRT的屏幕也会因高压吸附灰尘而降低亮度，使用者会不自觉的调大显示器的亮度，从而造成CRT过早老化。
对于面粉厂、水泥厂、煤矿等粉尘大的单位，要注意对计算机等外设的防尘。
为有效预防灰尘危害，确保显示器在相对干净的环境中使用，应该给显示器购买一个专用的防尘罩，每次用完后及时罩上(注意不要在关机后立即罩上，因为显示器在关机后需要一定时间来散热)。
4.光线显示器荧光屏绝对不能受阳光直射或其他强光照射，否则会加速CRT荧光粉的老化。
DIY攒机十招教你选液晶
在五一黄金周被传统节日的小长假取代之后，D I Y攒机的旺季也随之发生了转移，因为学生攒机而被关注的9月开学季销售期也成为新的黄金期，很多非学生用户也都会选择在这个期间出手。
与此同时，各个D IY厂商也都会选择在这个时期大搞促销，种类繁多的攒机配件对于很多消费者来说，无疑是一大难题。
在攒机配件的大件中，通常花费最多的液晶显示器的选购却最容易被忽视，特别是在目前市场各种促销和降价的混乱环境中，有没有选购窍门?小编试着总结了十条，希望能给大家选购液晶提供帮助。
诀窍一：购买之前先上圊了解液晶显示器有很多品牌，每个品牌又分不同尺寸和不同型号。
举个最简单的例子，一款19英寸宽屏的显示器有带D V I 接口和V G I接口的，有只有一个接口的，还有带H D M I接I：1等等。
消费者在去购买之前，—定要对相关的产品进行全面的了解，先要把～些基本的信息弄清楚了，看一下是不是与自己的需求匹配。
在上网了解相关资讯和用户评价之外，还可以查看一下目前液晶显示器的大致的市场行情，包括感兴趣的目标产品的价格。
如此一来，去市场采购的时候就会心里有底，不会被奸商黑了。
目前主流的尺寸是19英寸宽屏，也有不少预算充足的选购22英寸和24英寸以上的。
诀窍二：贷比三家，瑰场对比在电脑城选购的过程中，同～个品D I Y攒相十招教你选液晶10B r i l l i ant I deas f or L C DC hoi c e T e a chi ng Y ouD I Yi n A s s em bl y口刘颜婷牌的产品总是能看到不少商家在出售，售价有时候也会上下有一些差别。
这个时候消费者就要擦亮眼睛，在选购过程中一定要学会验货．同且寸最好能货比三家。
在验货过程中，可以自己随身带一些图片拷在u盘上，用自己的眼睛来明察秋毫，千万不能相信商家的忽悠。
通常来说，像三星等市场主流品牌的产品品质都比较过硬，因此在选购时注意验一下有没有亮点、彩点灯瑕疵就行，另外看一下外装箱内的配件是否齐全。
五种液晶显示器坚决不能买
五种液晶显示器坚决不能买2009年05月15日星期五下午03:53记得CRT时代，经济能力稍低的消费者购买15英寸CRT，主流显示设备基本仅有17英寸CRT可选。
转眼到了今天，CRT基本上淡出人们的选购范畴，LCD在市场中遍地开花。
可正是因为LCD的火爆，各种规格层出不穷，市场中10余种尺寸，宽屏与非宽屏等，这些区别了解起来或许不是那么困难，但实际选购的时候或多或少还是会遇到一些问题，使购买者举棋不定。
有鉴以此，泡泡网LCD频道总结出五种不能购买的LCD，希望能够帮助大家解决一些选购中的障碍，近期打算购买LCD的朋友千万不要错过哦。
●拒绝购买的液晶之一：17英寸宽屏LCD只要说起LCD，恐怕很多人首先联想到的是“宽屏”，的确，宽屏LCD虽然是个新型的产物，但宽屏LCD在06年所取得的辉煌成就是有目共睹的，这一年宽屏LCD不仅击败了传统LCD成为市场的绝对领袖，同时也为显示领域朝向宽屏之路奠定了坚实的基础。
说白了：17英寸宽屏LCD还不如17英寸LCD可能是宽屏实在太过于火爆了，不少厂商将宽屏战火蔓延到17英寸宽屏LCD，但从市场的反应来看，17英寸宽屏LCD并不受欢迎。
虽然市面上17英寸宽屏LCD款式并不多，但分辨率却有两种，分别是1280×720和1440×900，前者比分辨率1280×1024要少42%之巨，后者分辨率虽然不小（其实也小于1280×1024），但0.255mm的点距对使用者的眼睛发出严峻的挑战，如此一来，17英寸宽屏LCD不受欢迎也就不奇怪了。
而且现在生产17英寸宽屏液晶面板的也是一些二三线的小液晶面板厂，显示效果也没有优势。
事实上，拒绝17英寸宽屏LCD还有一个很明显的理由，LCD发展的趋势是高分辨率和大尺寸，17英寸宽屏LCD与这两项“背道而驰”，注定是昙花一现的LCD规格，也注定是没有任何前途的LCD规格，因此，我们认为17英寸宽屏LCD是应该被拒绝的。
购买液晶显示器必须谨防的七大陷阱(The seven traps that must be taken care of when buying LCDs)
购买液晶显示器必须谨防的七大陷阱（The seven traps that must be taken care of when buying LCDs）The seven traps that must be taken care of when buying LCDsAny product price depends largely on the cost, reduce the cost is the most effective way to improve profits, so all kinds of products are easy to cut corners on the cost of links, the liquid crystal display is no exception. Seemingly similar products, different manufacturers, different models, there are hundreds or even more than 1000 yuan gap, the reason is that there is a difference in cost.The panel level is the easiest to cut cornersA liquid crystal display seventy percent of the cost from the liquid crystal panel, a liquid crystal panel is a core component of liquid crystal display well, of course it is most likely to cut corners of parts.First of all, there are differences in performance of LCD panels, the performance of a more general LCD panel, but also a high angle of view, high contrast panel. Performance effect of liquid crystal display or not, basically by the choice of what the panel decided, bad JS is likely to be some shoddy, low performance products for superior performance products and Huyou expensive for such products only need to carefully check the information, the real performance can clear the product easy to distinguish.In addition, the liquid crystal panel the same performance whenthe sale of the factory was set at different levels, and different levels of panel prices are different, in order to reduce the cost only need to order a low level panel on the line. From the panel appearance is difficult to distinguish between the grade of the panel, so after all the panel assembled into a product from the sale is difficult to see the difference.To distinguish the grade of the panel, mainly to see the number of pixels of the panel, the less the number of pixels, and promised no highlights panel level is higher. The high level panel itself is light small, no other problems such as spots, color. The lower level of the panel have more or less problems, such as bad or more, there are stains, light is hard. That is to say, this is when the actual business classification panel factory by choosing to distinguish, good product quality, high grade, higher prices, or low goods or defective products, the price is certainly low. This classification standard is widely used in IT product parts.In fact, there are many LCD display giants are not specially customized proprietary LCD panels, but also with other two or three wire manufacturers in the same panel manufacturers procurement. But this kind of companies often pay much attention to the selection panel, is often selected a small part in a batch of LCD panel manufacturers in this part of the boutique course quality is higher than other products, high cost, the price of more expensive and very easy to understand.In fact, for their own use panel manufacturers quality often have a mental picture, agent told dealers to sell under the condition that a batch of products, because the panel qualityis poor, prone to bad dark spots and other issues. Of course, the faster you sell, the better. If the panel quality is good, manufacturers may also temporarily implement insurance policy on a batch of products, because manufacturers understand that these products are good, and the rate of rework will not be high.Hidden tricky in LCD product packagingDo not think that the product packaging is a box so simple, the product packaging involves many issues such as safety, environmental protection, in the mass production of industrial products, packaging is also very important, the cost is not low. If you don't see the discarded boxes, you can sell a few cents a kilo. A lot of people are scrambling for it, aren't they?Liquid crystal display good packaging is usually thick, in order to ensure the handling time will not be damaged, the raw materials are usually recyclable, environmentally friendly material, can find the logo on the packaging material circulation in general. In the packaging printing, pay more attention to the manufacturers usually printed on the built-in display appearance, but also as far as possible to provide information such as display, such as the type, size, weight, the approximate performance, the printed text is also a cost of printing less cost lower. More attention will also be paid to the beauty of the outer packing,The printed content can even include pictures and other information, very delicate. And in the outer packaging, Jerry manufacturers generally try to simplify these things, an outer package can be used for more than the specifications of similarproducts.In addition to the packaging itself, the internal filling material can not be ignored. The most common materials are recycled paper and foam plastics. Recycled paper is more expensive, and is usually seen on high-end displays. The foam is very popular. Because it is a by-product of petroleum, the price is very cheap.LCD products can also shrink functionFamiliar friends all know, the current field of liquid crystal display has an unwritten rule, a liquid crystal display usually launched with DVI interface and DVI interface with two models, and other specifications are almost exactly the same, of course, the price is also different. This is the most direct example of simplifying functionality and reducing costs. Of course, there are other ways to omit built-in speakers, microphones, USB interfaces, and so on.This functional simplification can effectively reduce costs without reducing most of the performance of the LCD display. "Shrink" version of the product will not be designed, using the "original" products of the scheme can be produced, is simply a rich product line, the clan of the two products can meet the needs of more people, in line with market rules.In fact, this "Jerry" can be regarded as a normal means, is not necessary as an abhorrence of the phenomenon, we cite the case is not to everyone choose functional products, if this function is of little significance for you, then choose "shrink"products is certainly more sensible.LCD products such as accessories can not be lessThe attachment is another very straightforward LCD display link. The usual LCD displays include cables, discs, instructions, and other mounting attachments. Any deductions or reductions in quality can reduce costs.The most common example is the double interface display should equipped with DVI and VGA two cable chisel DVI line, can save part of the cost, dual interface display is more high-end products, two lines are basically there will be now, with the popularity of DVI, many entry-level display also has this interface, but the DVI line is usually omitted.In addition to simply do not give, the quality of cable is also very common. First, say the VGA signal line, which is easiest to see. OK, VGA line diameter is coarse, and flexible and elastic, and the joint part is exquisite, without burr. The poor quality VGA wire is not only very thin, but the wire is very crisp and the quality of the joint is not good. At present, many low display VGA lines have shrunk seriously, many brands attached to the VGA line is actually only a little bit thick than the keyboard line. All this comes with a VGA line machine, a grade not high. The DVI line is roughly the same as the VGA line.In addition to the signal line, the power line also shows the problem. Good lines of flexible material, and the length is generally 1 meters, 5 to 2 meters or so, the difference in thelength of the line has shrunk, the corresponding material requirements are reduced. Then, you can see through the signal line interface authentication said good sign line has a lot of, what the EU, Japan, the United States, and China's CCC, the line is through multinational certification, quality guaranteed. Poor line certification is rare, and some are not available at all. If the monitor comes with speakers, what should also pay attention to cable, good audio lines have degaussing ring, high cost. Of course, of course not. However, the audio lines attached to the monitor are all the same, and it is rare to see cables with degaussing loops.Transformer is also part of the important accessories display, good quality and quality in general, the middle of great flexibility. However, at present, many display manufacturers prefer to use built-in power, so that the cost of their own master, or control.In addition to the cable can make a big article, save the drive CD-ROM, instructions are the same. Although the cost of these parts is not high,But in the mass production of industrial products, the amount accumulated is not small.Product shell prone to Jerry buildingThe biggest cost outside the LCD panel is the shell, which is the most important part of the display manufacturers. LCD manufacturers have a special design and R & D team for the shape of the products, and the current LCD can easily distinguish themanufacturers from the design. The large brand LCD often has unique design in appearance and shape, but the small factories with insufficient strength often adopt simple shape design, or imitate other excellent products. Since there is so much knowledge on the shell, so much effort has been put into it, of course, it is very easy to cut corners.First, simplify the design as much as possible. For example: plastic shell display commonly used are smooth and pitted, which pitted the surface than expensive, if the housing is designed into a light, the cost is naturally designed than cheap noodles. In addition, in the shape design can also adopt the gradual method, only on the original basis to do some minor adjustment, so that you can use as much spare parts as possible, so that the cost savings.Secondly, it can reduce the material of the shell. The most common material for liquid crystal displays is plastic, and a small number of high-grade metal housings, such as AOC and 174F, are integral steel shells, and Samsung 193P+ even uses aluminum magnesium alloy housings. Cast aside the metal shell, not to say, plastic shell is also a variety of, of which the most important is the material is different, good plastic material is environmental protection, fire, and some less is not so good. In general, the quality of good display, fire plastic shell, at least the cost of 200 yuan or so, if the unique shape, but also more expensive. As far as metal is concerned, let alone.Finally, work hard on the mold. Many people may not know, in fact, die spending is one of the highest cost of project display manufacturing and R & D cost is very simple! Even if theappearance of the display, the light mold cost will be about 1000000! And die cannot old, midway requires a lot of maintenance in order to maintain the quality of housing, even if it is to maintain the good die there life, wear to a certain extent is useless, must spend a lot of money to do the new. If the manufacturers want to reduce housing costs, the mold can continue to use at end-of-life degree under the condition, this can save a lot of mold cost, but the shell accuracy will be greatly affected, will be very rough.TCO, RoHS certification BasicsIn order to ensure safety, environmental protection and other factors, some industrialized products have certain standards to be implemented, that is, we usually say certification, only in compliance with these certification in order to allow users to ease their use. Certification of this item in general goods can not see, can not touch, and when more certified products must have more advantages. And this is just one icon on the monitor, similar to the invisible cost, also need manufacturers pay a great deal of price. Through these certification is not free, in accordance with the certification bodies, fees are different, it costs a lot.At present, China's implementation of CCC mandatory security certification of display products, as long as it is not inferior products will pass this certification. The rest of the common certifications include the CE European common market security mark, Japan's JIS logo, the British BEAB logo, the US UL logo, the French NF logo, and the German CS logo. If the display in the domestic sales, it only needs to pass CCC, and if sold inthe countries mentioned above, it is necessary to pass the country's certification, obtain certification.In addition to the safety certification that electronic products must carry out, there are some professional certifications, such as MPR, II, TCO, and the current popular RoHS.Among them, MPR II is about the monitor radiation certification, is a relatively basic standard, almost all monitors can meet this standard. TCO is the certification of environmental protection, and RoHS is the certification of lead-free process production.TCO certification is a Swedish Labor Union developed a series of strict and standard for display products, only in ecology, energy, radiation, human engineering and electrical safety five aspects are in line with the TCO Development standards, can through the TCO version certification. TCO is currently recognized as the most stringent authentication system in the field of display, and the display of this specification can provide maximum protection for users. Currently, TCO has released the 06 standard.RoHS (Restriction, of, Hazardous, Substances, hazardous substances restrictions) is an official certification of the European Union (Figure 1), known by the industry as the world's most stringent environmental directives. According to the relevant provisions of RoHS certification standards, since July 1, 2006, all sold in the EU market of electrical and electronic equipment must prohibit the use of lead (Pb),mercury (Hg), cadmium (Cd), six chromium (Cr6+) and other heavy metals, and polybrominated diphenyl ether (PBDE two) and polybrominated biphenyls (PBB) and other harmful substances. Of course, RoHS's influence is not limited to Europe. It is becoming a global standard. The relevant laws and regulations of our country have already entered the "bulletin" stage, and we believe it will be published and implemented soon.To pass these certification is not easy, first of all, the product should be strict security certification, design requirements, all aspects can not be careless, so as to increase the production cost of the product. According to statistics, a monitor through certification requires about 200 thousand of the cost, although there are domestic commissioning units, but the licensing rights in foreign countries. The average display takes about 2 months, so the cost of a small certification is never low. These long-term environmental protection and lead-free considerations, is clearly not in line with the idea of JS, so many small plants in addition to electrical safety certification necessary, of course, all the other certification.Other cost control for LCD productsIn addition to the aforementioned aspects, there are also parts of the LCD that can be "cost control", including control modules and power modules.Position control module in liquid crystal display is equivalent to the personal computer motherboard, display control function of it all, and the power supply module is for power management,they are in the form of integrated circuit board integrated in liquid crystal display device, and integrated circuit board in the "cost savings" place very much. From PCB to all kinds of electronic components selection, can be very different. For example, PCB version, the cheapest single board, there are more expensive multi-storey board, good board, high security, integration is good, but the price is not cheap. Even components of the same specifications on an integrated circuit board may differ in quality, such as fire resistance and durability, and will lead to the final cost difference.In addition, the function of the control panel also plays a decisive role in the cost. For example, to realize the gray scale response time, we must join the corresponding chip, and the design of the board should also be taken into consideration. More functions of the board, less expensive than the function of a lot of money. At present, a simple control board will cost nearly 300 yuan, not to mention more functions.epilogueAfter watching this, I believe you not only for the production of the LCD and part of a certain understanding, choice of technology, complete materials carefully consideration while products will increase the cost, but you use the product safety and comfort can get the best guarantee. More importantly, you should know how to distinguish between the advantages and disadvantages of LCD monitors, and then face the JS Huyou, you will not easily caught.LastDon't easily believe all kinds of propaganda on the internet.。

LG L222WT和L225WT之间只差一个字符，但价格相差了200元
很多人认为，型号比较相似的液晶显示器，功能应该比较相近，因此价格也非常接近，即使被一些不发商贩“忽悠”了，损失也不会太大。
但事实上并非如此。
如LG的一款21.6英寸宽屏液晶L222WT和22宽屏L225WT，这两款液晶不论在外观、性能参数还是在接口配备上都完全相同，两者虽然在屏幕尺寸上仅仅只有0.4英寸的差距，但价格方面却有200元的差价。
一些不法商贩会将这些21.6宽屏当作22宽屏推荐给消费者，从中赚取较大的利润。
而对型号不是很熟悉的消费者，则会很容易上当，为此多支付200元。

●液晶显示器型号繁多
目前，很多厂商都推出了各自的液晶显示器产品，主流的液晶显示器品牌就有六到七个，并且如三星和LG等大品牌的产品线都非常丰富，而每一款液晶显示器都有唯一的型号，因此要记住每一款液晶显示器的型号、并了解它的性能参数是一件非常不容易的事情，消费者在选购时也会感到非常困扰。
