Display 调试问题点
一、Display1.lcm 相关概念1.1) MIPI接口：一共有三种接口：DBI(也做CPU或MCU接口)、DPI(也叫RGB接口)、DSI.在使用DSI接口时，目前75/77都只支持到2条data lane，加上一条clock lane.使用DPI接口时，根据LCM IC支持的情况，可以选择16bus、18bus传输RGB格式文件，在GPIO 部分分为R、G、B分别对应8个GPIO(GPIO20~46期间)，客户采用DPI接口需要根据选择的bus方式进行配置，推荐RGB端口全部配置为对应的复选模式，并设置为OUT输出。
采用DBI接口，有两种模式选择，一种是选择共用DPI的bus脚+DPI控制线，另一种是共用nand data pin+CPU 控制线。
1.2) DSI接口有两种sync 模式：video mode和command mode，其中video mode是BB端一直刷数据到LCM，cmd mode是在有数据更新时刷数据到LCM GRAM中)和DSI command mode相比，video mode 是需要实时传输image data到lcm端，DSI 的refresh rate决定了lcm的refresh rate。
1.3)EDS机制：92平台LCM driver中定义了esd_check和esd_recovery的接口，但ESD线程不工作。
目前在MT6589之前平台，video mode的ESD实现有三种模式，分别是：ext TE(外部TE信号检测)、int TE(内部TE信号检测)、non cout clk不同ESD方式需要注意的方面a) int TE和ext TE的检测，都不需要实现lcm_esd_check函数，而需要实现lcm_esd_recover函数。
non cont clk则不需要实现lcm_esd_check函数和lcm_esd_recover函数，而只需要在上面params中配置为TRUE即可b) ext TE的实现，需要LCM外接TE pin到BB端，同时在inital code中配置寄存器打开TE信号的输出(一般是写0x35寄存器，具体需要和LCM IC FAE确认)1.4)HDMI/MHL:目前我司HDMI/MHL的相关code和driver都是有集成在codebase中的，要使用的话，只需要只需要在对应的ProjectConfig.mk文件中开启，并且在dct中配置好对应的引脚定义即可。

LTC2449演示电路742快速入门指南说明书
QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 7428/16 CHANNEL HIGH SPEED DELTA SIGMA ADCLTC2449 DESCRIPTIONThe LTC®2449 is an 8/16 channel, high speed, 24-bit∆Σ ADC with ten selectable speed / resolution modesfrom 6.9Hz/200nVRMS to 3.5 kHz/25µVRMS. Key DCspecifications include 5ppm INL, 5µV offset, 10ppm full-scale error and 20nV/°C offset drift. In the6.9Hz/200nVRMS mode, input normal mode rejection of50Hz and 60Hz noise is better than 87dB. The accu-racy (offset, full-scale, linearity, drift) and power dis-sipation are independent of the speed selected. The LTC2449 performs autozeroing of the ADC by revers-ing the inputs through the multiplexer output / ADC input connections. This allows an external dual buffer amplifier to isolate the signal inputs from the sam-pling current of the ADC. DC742 is a member of Linear Technology‘s QuickEval™ family of demonstration boards. It is de-signed to allow easy evaluation of the LTC2449 and may be connected directly to the target application’s analog signals while using the DC590 USB Serial Controller board and supplied software to measure performance. The exposed ground planes allow proper grounding to prototype circuitry. After evaluat-ing with LTC’s software, the digital signals can be connected to the application’s processor / controller for development of the serial interface.Design files for this circuit board are available. Call the LTC factory.LTC is a trademark of Linear Technology CorporationQUICK START PROCEDUREConnect DC742 to a DC590 USB Serial Controller us-ing the supplied 14 conductor ribbon cable. Connect DC590 to host PC with a standard USB A/B cable. Run the evaluation software supplied with DC590 or downloaded from . The correct pro-gram will be loaded automatically. Click the COLLECT button to start reading the input voltage. Click the slider at the bottom of the strip-chart display to change the oversample ratio (OSR) which will in turn change the data output rate. Tools are available for logging data, changing refer-ence voltage, changing the number of points in the strip chart and histogram, and changing the numberof points averaged for the DVM display.HARDWARE SET-UPJUMPERSJP1, JP2 – Select the positive and negative supply voltages for the onboard amplifier. Supplies can be GND and Vcc or supplied externally.JP3, JP5 – Select the source for REF+ and REF-, respectively. REF+ can be 5.00 volts from the on-board LT1236 reference (default) or supplied exter-nally. REF- can be Ground (0 volts, default) or sup-plied externally.JP4 – Select source for analog COM input, either tied to ground or supplied externally to the COM turret post.JP6 – Trigger mode, either normal (default) or ex-ternally triggered.JP7 – Trigger input signal. Pin 1 is a 5-volt logic signal, pin 2 is ground. When triggered mode is selected on JP3, a rising edge starts a new conver-sion. Note that since a conversion cannot be termi-nated once started, this signal can only be used to slow down the conversion rate.CONNECTION TO DC590 SERIAL CONTROLLERJ2 is the power and digital interface connector. Connect to DC590 serial controller with supplied 14 conductor ribbon cable.ANALOG CONNECTIONSAnalog signal connections are made via the row of turret posts along the edge of the board. Also, if you are connecting the board to an existing circuit, the exposed ground planes along the edges of the board may be used to form a solid connection be-tween grounds. GND – Ground turrets are connected directly to the internal analog ground plane.PWR GND – Power ground, connected to the power return trace.VCC – This is the supply for the ADC. Do not draw any power from this point. External power may be applied to this point after disabling the switching supply on DC590. If the DC590 serial controller is being used, the voltage must be regulated 5 volts only, as the isolation circuitry will also be powered from this supply. See the DC590 quick start guide for details.REF+, REF- - These turrets are connected to the LTC2449 REF+ and REF- pins. If the onboard refer-ence is being used, the reference voltage may be monitored from this point. An external reference may be connected to these terminals if JP3 and JP5 are configured for external reference.Note: The REF+ and REF- terminals are decoupled to ground with 0.1µF and 10 µF capacitors in paral-lel. Thus any source connected to these terminals must be able to drive a capacitive load and have very low impedance at DC. Examples are series ref-erences that require an output capacitor and C-load stable op amps such as the LT1219 and LT1368. CH0 – CH15 – These are the differential inputs to the LTC2449. They may be configured either as sin-gle –ended inputs with respect to the COM pin, or adjacent pairs may be configured as differential in-puts (CH0-1, CH2-3, etc.)EXPERIMENTSINPUT NOISESolder a short wire from the CH0 to CH1. Ensure that the buffer amplifiers are in their active region of operation by either biasing the inputs to mid – sup-ply with a 10kΩ-10kΩ divider when the buffer am-plifier is powered from Vcc and ground, or tie the inputs to ground and connect an external +7.5V / -2.5V supply to the AMPV- turret (JP1 and JP2 must be set to EXT.)Set the demo software to OSR32768 (6.8 samples per second.) and check the 2X box. Noise should be approximately 0.04ppm of Vref (200nV.) Next, se-lect different oversample ratios. Measured noise for each oversample ratio should be close to values given in the LTC2449 Data Sheet.COMMON MODE REJECTIONTie the two inputs (still connected together from previous experiment) to ground through a short wire and note the indicated voltage. Tie the inputs to REF+; the difference should be less than 5 µV due to the 120 dB CMRR of the LTC2449.This experiment requires an external power supply to the buffer amplifier.If the common mode voltage is limited to GND+0.25V to Vcc-0.25V, this test may be per-formed with the amplifier supplies set to ground and Vcc.INPUT NORMAL MODE REJECTIONThe LTC2440’s SINC4 digital filter is trimmed to strongly reject both 50 and 60 Hz line noise when operated with the internal conversion clock and oversample ratio 32768 (6.8 samples per second.) To measure input normal mode rejection, connect COM to a 2.5 volt source such as an LT1790-2.5 reference or a power supply. Connect any other input (CH0 – CH15) to the same supply through a 10kΩ resistor. Apply a 10 Hz, 2V peak-to-peak sine wave to the input through a 1uF capacitor.Select OSR32768 (6.8 samples per second) and 2X mode in the demo software and start taking data. The input noise will be quite large, and the graph of output vs. time should show large variations. Next, slowly increase the frequency to 55 Hz. The noise should be almost undetectable in the graph. Note that the indicated noise in ppm may still be above that of the datasheet specification because the inputs are not connected to a DC source. Change the OSR to 16384 (13.75 samples per sec-ond;) the noise will increase substantially, as the first notch at this OSR is at 110 Hz. Increase the signal generator frequency to 110 Hz, the noise will drop again.。

amd显卡,10bit⾊彩设置AMD’s 10-bit Video Output Technology IntroductionDisplay devices with a greater bit depth than the conventional 8-bits per color channel are rapidly gaining popularity in application areas such as medical imaging, professional photography, graphics design, movie production, and entertainment in general. What makes these devices attractive to a wide array of fields is their ability to represent colors with a greater fidelity than it is possible with conventional display devices. This means what we see in the real world more accurately matches what we see on the screen, ensuring that design and diagnosis errors due to monitor limitations are minimized.In order to benefit from the increased bit depth of these display devices, graphics cards used to drive them should be capable of outputting higher bit depth information as well. For example, if a display device supports 10-bits per color channel input, its capacity will not be fully exploited unless the graphics card outputs a matching bit depth. This is where AMD’s most recent series of workstation graphics cards come into play by natively supporting the emerging standard for 10-bits per color channel (or 30-bits per pixel) video output.In this paper, we first emphasize the necessity of higher bit depths for color critical tasks followed by an overview of the 10-bit monitors currently available. We then demonstrate how users can easily benefit from this technology using AMD’s graphics cards capable of 10 bit output.The Need for 10-bit DisplaysConventional display devices use 8-bits per color channel (or 24-bits per pixel) to display images and video. Although this amounts to more than 16 million colors, it still corresponds to a fraction of the colors we perceive in the real-world. This is illustrated in Figure 1, where the green triangle shows the boundaries of the sRGB1 color space on the CIE-xy chromaticity diagram. Conventional sRGB compliant 8-bits monitors can only represent the colors that lie in this triangle, while the human eye is capable of perceiving all the colors in the entire chromaticity diagram. This discrepancy is further emphasized by the fact that today’s most professional cameras and printers have a color gamut larger than that of sRGB (such as Adobe RGB2 shown by the red triangle in Figure 1), creating a bottleneck on the display side. Figure 2 demonstrates this problem where the blue areas in a photograph taken with the Adobe RGB setting of a camera cannot be accurately represented on a conventional monitor.To solve this problem, display devices can operate in a color space with a larger gamut than that of the sRGB. This can be achieved by using purer (more saturated or monochromatic) primaries to stretch the1 sRGB is a standard color space proposed by HP and Microsoft to allow for consistent color reproduction on typical monitors, printers and the Internet. It has the same primary set as the HDTV also known as ITU-R BT. 709.2 Adobe RGB is an RGB color space with a larger gamut than sRGB. It is developed by Adobe with the printing industry in mind, as there were many colors that can be printed but not displayed by a smaller gamut color space.corners of the color gamut toward the edges of the chromaticity diagram. However, when the color gamut is expanded, using only 8-bits per color channel ceases to be sufficient to display a smooth image without banding artifacts. This is illustrated in Figure 3 with a sample set of colors in both sRGB and Adobe RGB color spaces. Note that, the spacing between the color samples increases in the Adobe RGB space since it occupies a larger area. Another example is shown in Figure 4, where only 6-bits are used to cover what should normally be an 8-bit range. Similar problems will occur if 8-bits are used to cover what should normally be a 10-bit, that is, a larger range. Therefore to convey a smooth image, one needs to use additional shades of colors, hence the need for 10-bit displays.Figure 1: The 2D color gamut of the sRGB and Adobe RGB color spaces are superimposed on the CIE-xy chromaticity diagram. Note that the colors shown inside the diagram are for illustration purposes.blue areas show the out-of-gamut colors.which may lead to banding artifacts. To avoid this problem, the bit depth of the display device needs to be increased.Figure 4: This figure illustrates the banding artifacts that would occur if a smaller number of bits are used to cover a larger color range. For illustration purposes 6-bit are used to cover a subset of the 0-255 range – similar artifacts will occur if 8-bits are used to cover a larger color space such as the Adobe RGB.10-bit Display Devices10-bit displays use 10 bits to represent each of the red, green and blue color channels. In other words, each pixel is represented with 30 bits, instead of the 24 bits used in conventional displays. To this end, 10-bit displays can generate more than a billion shades of colors.In medical imaging, display devices with higher bit depths have already been in use as they allow for more accurate identification and diagnosis. Two examples of medical displays that support 10-bits are Barco Coronis 5MP Mammo and Eizo GS510. Both are grayscale displays and are commonly used in mammography applications. There exist full color 10-bit medical displays as well such as the Eizo RadiForce R31, which can be used to visualize MRI, PET, and CR scans. Higher bit depth display devices are also entering the mainstream in graphics design, professional photography, compositing, and cinema post production. Recently HP unveiled DreamColor LP2480zx, which is a 24” LED backlit LCD display capable of presenting 30-bits per pixel color information. Another 30-bit display was introduced earlier by NEC (LCD2180WG-LED), which also uses LEDs to back light the LCD panel. Both of these displays prefer LED backlighting instead of the more traditional Cold Cathode Fluorescent Lamps (CCFL), since LEDs offer a much narrower color spectrum than fluorescents, enabling more saturated primary colors. Both the HP and the NEC display are capable of accurately representing the entire Adobe RGB color gamut.AMD’s 10-bit Display SupportAMD’s most recent series of workstation graphics cards give full support to various types of 10-bit displays including all of the models mentioned above. The communication interface can currently be single link DVI, dual link DVI, and DisplayPort depending on the input/output ports configuration of the monitor and the graphics card. Through a proprietary packed pixel format, very high resolution grayscale medical displays can be natively supported through a single link DVI. Figure 5 demonstrates how the user can enable the 10-bit display support in the OpenGL driver by simply checking the relevant checkbox in the Catalyst? Control Center (CCC).Figure 5: 10-bit display feature can be enabled by checking the “Enable 10-bit pixel format support” checkbox in the Catalyst Control Center. Note that this feature is only available in workstation (ATI FireGL?) cards.Once the 10-bit pixel format support is enabled the system will request a reboot and after that any 10-bit aware OpenGL application will be displayed in 10-bits without any clamping. In the following, we demonstrate how an application programmer can easily create a 10-bit aware OpenGL application. Choosing a 10-bit Pixel FormatThe first step in creating a 10-bit OpenGL application is choosing an appropriate pixel format. Depending on the windowing library used, this can be achieved in slightly different ways. We first demonstrate the GLUT method followed by theWGL_ARB_pixel_format extension approach.GLUTTo request a 10-bit pixel format in GLUT, the user needs to specify the appropriate display string before creating an OpenGL window using:// request 10 bit colors, a depth buffer, and double bufferingglutInitDisplayString("red=10 green=10 blue=10 depth double");After this call, any OpenGL window created with glutCreateWindow() will have a 10-bit per color channel pixel format (the window does not have to be in fullscreen). This can be verified by querying the number of bits for each color channel:// verify that each color channel has 10 bitsint red_bits, green_bits, blue_bits;glGetIntegerv(GL_RED_BITS, &red_bits);glGetIntegerv(GL_GREEN_BITS, &green_bits);glGetIntegerv(GL_BLUE_BITS, &blue_bits);WGL_ARB_pixel_format ExtensionA 10-bit pixel format can also be requested using the wglChoosePixelFormatARB()function provided by theWGL_ARB_pixel_format extension as shown below:HDC device_context; // set previous to this codeint attribs[64] = {TRUE,WGL_SUPPORT_OPENGL_ARB,TRUE,WGL_DRAW_TO_WINDOW_ARB,WGL_PIXEL_TYPE_ARB, WGL_TYPE_RGBA_ARB, 10,WGL_RED_BITS_ARB,10,WGL_GREEN_BITS_ARB,10,WGL_BLUE_BITS_ARB,WGL_DEPTH_BITS_ARB, 24,WGL_DOUBLE_BUFFER_ARB, TRUE,// zero terminates the list0,};static float fattribs[64] = {// zero terminates the list0.0f,};const int format_max = 256;int formats[format_max];unsigned int format_count; wglChoosePixelFormatARB(device_context, attribs, fattribs, format_max, formats, &format_count);// "format_count" suitable formats are in "formats".if(format_count == 0) {// there were no suitable formats} else {// For this example we just use the first match.result = SetPixelFormat(device_context, formats[0], &pfd); if(result == 0) {// error can be retrieved from GetLastError()}Creating a 10-bit TextureThe previous section highlighted several methods to choose a 10-bit pixel format. It is important to note that once a 10-bit pixel format is chosen any smooth shading operation will immediately take advantage of the increased bit depth. In other words, the user does not need to explicitly provide 10-bit input data to benefit from the increased precision. This is due to the fact the internal processing of colors in the graphics card is in floating-point precision with 10-bit (or 8-bit) conversion occurring only at the output stage.However, it is also possible to explicitly create and work with 10-bit textures as will be explained in this section. 10-bit texture support is exposed to the user through a packed RGB10_A2 texture format, which contains 10 bits for each of the color channels and 2 bits for the alpha component. For convenience, we can start by defining an auxiliary union which can be used to set the values of a 10 bit texture:// Auxiliary union used to set the values of the 10 bit textureunion format2_10_10_10{struct {unsigned int red :10;unsigned int green:10;unsigned int blue :10;unsigned int alpha:2;} bits;unsigned int u32All;};Next we allocate a memory buffer which will be filled with the user data:// Allocate a buffer which will be used as the 10 bit textureint drawWidth, drawHeight;format2_10_10_10* drawData = new format2_10_10_10 [drawWidth * drawHeight];After the buffer is successfully created, it can be filled with user data coming from any 10-bit source such as a DICOM image or a RAW camera output:// Fill the buffer with values from the user. userRed, userGreen,// and userBlue are unsigned integers in the range [0,1024].format2_10_10_10 aux;for (int y = 0; y < drawHeight; ++y)for (int x = 0; x < drawWidth; ++x){aux.bits.red = userRed; // user inputaux.bits.green = userGreen; // user inputaux.bits.blue = userBlue; // user inputdrawData[x + y * drawWidth].u32All = aux.u32All;All that remains to be done is to create a 2D texture, specify the buffer we just filled in as the texture data source, and set the desired texture parameters:// Create and bind a new textureGLuint texID;glGenTextures(1, &texID);glBindTexture(GL_TEXTURE_2D, texID);// Fill the texture image from the 10 bit buffer dataglTexImage2D(GL_TEXTURE_2D, 0, GL_RGB10_A2, drawWidth, drawHeight,0, GL_RGBA, GL_UNSIGNED_INT_2_10_10_10_REV, drawData);// Set desired texture parametersglTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);Finally, we map the texture on a screen size quad for display on the screen:// Map the texture on a screen size quad for displayglEnable(GL_TEXTURE_2D);glBegin(GL_QUADS);glTexCoord2f(0.0, 0.0);glVertex2f(0.0, 0.0);glTexCoord2f(0.0, 1.0);glVertex2f(0.0, drawHeight);glTexCoord2f(1.0, 1.0);glVertex2f(drawWidth, drawHeight);glTexCoord2f(1.0, 0.0);glVertex2f(drawWidth, 0.0);glEnd();This sample code demonstrated how to create and display a 10-bit per color channel texture with input data explicitly specified by the user. Additionally, for off-screen rendering, 10-bit textures can be attached as render targets (i.e. color attachments) to framebuffer objects.ConclusionsAs a result of the enhanced presentation quality enabled by higher bit depths, 10-bit displays are rapidly becoming norm rather than exception in application areas such as medical imaging, professional photography, graphics design, compositing, and post production. To realize their full potential, these displays demand a higher bit depth video output from the graphics cards that are used to drive them. AMD’s most recent series of workstation cards are designed to meet this demand by natively supporting 10-bits, ensuring that crucial information is never lost in any stage of the rendering and display pipeline.Further ReadingR.

►Cholesteric:
► A cholesteric liquid crystal is a type of liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as chiral nematic liquid crystals. They organise in layers with no positional ordering within layers, but a director axis w hich
varies with layers. The variation of the director axis tends to be
periodic in nature. The period of this variation (the distance o ver which
a full rotation of 360°is completed) is known as the pitch, p. The pitch
is varying with temperature and it can also be affected by the
boundary conditions when the chiral nematic liquid crystal is
sandwiched between two substrate planes.
