Twisted stress) is notapplied to the module.And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module.(3) Please attach a transparent protective plate to the surface in order to protect the polarizer.Transparent protective plate should have sufficient strength in order to the resist external force.(4) You should adopt radiation structure to satisfy the temperature specification.(5) Acetic acid type and chlorine type materials for the cover case are not describe becausethe former generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electro-chemical reaction.(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harderthan HB pencil lead. And please do not rub with dust clothes with chemical treatment.Do not touch the surface of polarizer for bare hand or greasy cloth. (Some cosmetics are determined to the polarizer)(7) When the surface becomes dusty, please wipe gently with adsorbent cotton or other softmaterials like chamois soaks with petroleum benzene. Normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer.(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizercauses deformations and color fading.(9) Do not open the case because inside circuits do not have sufficient strength.15.2 OPERATING PRECAUTIONS(1) The spike noise causes the mis-operation of circuits. It should be lower than followingvoltage：V=±200mV(Over and under shoot voltage)(2) Response time depends on the temperature. (In lower temperature, it becomes longer.)(3) Brightness depends on the temperature. (In lower temperature, it becomes lower)And in lower temperature, response time (required time that brightness is stable after turned on) becomes longer.(4) Be careful for condensation at sudden temperature change. Condensation makes damageto polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur.(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.(6) Module has high frequency circuits. Sufficient suppression to the electromagneticinterference shall be done by system manufacturers. Grounding and shielding methods may be important to minimize the interference.15.3 ELECTROSTATIC DISCHARGE CONTROLSince a module is composed of electronic circuits, it is not strong to electrostatic discharge.Make certain that treatment persons are connected to ground through wristband etc. And don’t touch interface pin directly.15.4 PRECAUTIONS FOR STRONG LIGHT EXPOSUREStrong light exposure causes degradation of polarizer and color filter.15.5 STORAGE When storing modules as spares for a long time, the following precautions are necessary. (1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5℃ and 35℃ at normal humidity. (2) The polarizer surface should not come in contact with any other object. It is recommended that they be stored in the container in which they were shipped. 15.6 HANDLING PRECAUTIONS FOR PROTECTION FILM (1) When the protection film is peeled off, static electricity is generated between the film and polarizer. This should be peeled off slowly and carefully by people who are electrically grounded and with well ion-blown equipment or in such a condition, etc. (2) The protection film is attached to the polarizer with a small amount of glue. Is apt to remain on the polarizer.Please carefully peel off the protection film without rubbing it against the polarizer. (3) When the module with protection film attached is stored for a long time, sometimes there remains a very small amount of glue still on the polarizer after the protection film is peeled off. (4) You can remove the glue easily. When the glue remains on the polarizer surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal-hexane. 15.7 Cautions for installing and assembling Bezel edge must be positioned in the area between the Active area and View area. The bezel may press the touch screen and cause activation if the edge touches the active area. A gap of approximately 0.5mm is needed between the bezel and the top electrode. It may cause unexpected activation if the gap is too narrow. There is a tolerance of 0.2 to 0.3mm for the outside dimensions of the touch panel and tail. A gap must be made to absorb the tolerance in the case and connector.。

Contrast Ratio(CR) is defined mathematically as below, for more information see Figure .Contrast Ratio =Average Surface Luminance with all white pixels (P1,P2,P3,P4,P5) Average Surface Luminance with all black pixels (P1,P2,P3,P4,P5)Note 2. Surface luminance is the LCD surface from the surface with all pixels displaying white. For more information, see Figure .Lv = Average Surface Luminance with all white pixels (P1, P2, P3, P4, P5)Note 3.The uniformity in surface luminance δ WHITE is determined by measuring luminance at each test position 1 through 5, and then dividing the maximum luminance of 5 points luminance by minimum luminance of 5 points luminance. For more information, see Figure .δ WHITE =Minimum Surface Luminance with all white pixels (P1,P2,P3,P4,P5) Maximum Surface Luminance with all white pixels (P1,P2,P3,P4,P5)Note 4. Response time is the time required for the display to transition from white to black (Rise Time, Tr) and from black to white (Decay Time, Tf). For additional information see FIG 1. The test equipment is Autronic-Melchers’s ConoScope series.Note 5.CIE (x, y) chromaticity, the x, y value is determined by measuring luminance at each test position 1 through 5, and then make average value.Note 6. Viewing angle is the angle at which the contrast ratio is greater than 2. For TFT module the contrast ratio is greater than 10. The angles are determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface. For more information see Figure .Note 7. For viewing angle and response time testing, the testing data is based on Autronic-Melchers’s ConoScope series. Instruments for Contrast Ratio, Surface Luminance, Luminance Uniformity, CIE the test data is based on TOPCON’s BM-5 photo detector.Note 8. For TFT module, Gray scale reverse occurs in the direction of panel viewing angle.Figure 2. The definition of response timeFigure 3.

一、LCD分类(1)STNSuper Twisted Nematic,超扭曲向列，有CSTN和DSTN之分，是4中LCD 屏中最低端的一种，仅有的优点是功耗低,响应时间约200ms.(2)TFTThin Film Transistor,薄膜晶体管.功耗稍高，响应时间约80ms.(3)LTPSLow Temperature Polycrystalline Silicon,低温多晶硅.由TFT衍生的新一代产品,响应时间约12ms.由于这类液晶屏幕的制造需要高于制造传统TFT屏，目前仅有少数知名厂商能制造.(4)OLEDOrganic Light Emitting Diode,有机发光二极管,可视角度非常大,功耗很低，是未来发展的主流.二、LCD参数(1)尺寸一般液晶屏使用对角线的长度表示屏幕的大小,单位是英寸.(2)分辨率(Resolution)一幅图像被称作一帧(frame),每帧有若干行、列的像素数组成,常见的分辨率如下:320*240(QVGA) 640*480(VGA) 800*480(WVGA)800*600(SVGA) 1280*800(WXGA)(3)PPIpixels per inch.在图像中,每英寸所包含的像素数,也是描述一个图片信息的重要属性.图像的ppi值越高,画面的细节就越丰富.常见的ppi值有72ppi、180ppi、300ppi.(4)色深(色位)每个像素的颜色使用若干位的二进制数据来表示，单位是BPP(bit per pixel).常见色深有:<1>8BPP : 2^8=256色,每个像素颜色使用8bit二进制数表示,即一个像素点有256种颜色.但对与三种原色平均下来，每种原色只能使用不到3位的数据来表示，即每个原色最多不过8个级别，这不足以表示更丰富的色彩.为了解决该问题，需要调用调色板.每个像素对应的8位数据不再表示RGB三种原色，而它在调色板中的索引值.要显示某像素时，使用该索引值从调色板中取得RGB颜色.<2>16BPP : 2^16=65k色,称作伪彩色,每个像素颜色使用16bit二进制数表示,即一个像素点有65k种颜色.每个像素点的颜色使用两个字节来表示，这两个字节的数据格式又分为两种: 5:6:5、5:5:5:1,前者使用高5位表示红色，中间6位表示绿色，低5位表示蓝色；后者的高15位从高到低分成3个5位来表示红色、绿色、蓝色，最低位表示透明度.故5:5:5:1的数据格式又称作RGBA格式(A:Alpha,表示透明度).<3>24BPP : 2^24=16M色,称作真彩色,每个像素颜色使用24bit的二进制数表示,即一个像素点有16M种颜色.每个像素点的颜色使用三个字节来表示，每种原色使用8bit，LCD控制器通过VD[23:0]数据线发送给LCD.为了方便DMA 传输，在内存中使用4个字节来表示一个像素，其中3个字节从高到低分别表示红、绿、蓝，剩余一个字节无效.是最低字节还是最高字节无效，这是可以选择的.【attention】LCD一帧数据的字节数,或者说一幅图片的字节数=像素点数*色深如16BPP的320*240的LCD,其一帧数据的字节数=320*240*2=153600 (5)点位图点位图法是把一幅图像分成许许多多的像素，每个像素用若干个二进制位来指定该像素的颜色、亮度和属性.因此一幅图像由许许多多描述每个像素的数据组成，这些数据通常称为图像数据，而这些数据通常是作为一个文件来存储的，这种文件又称为图像文件.(6)基色根据色彩学原理，现实世界上的任何颜色可由红绿蓝三种颜色的不同强度混合而成，这三种颜色称为基色或原色.(7)灰度级灰度也可认为是亮度,特指每种基色的发光亮度.将基色的发光亮度按强度大小划分，就是灰度级.显示屏能产生的灰度级越高，显示的颜色就越多，但造价也更高.例如:4级(=2^2)灰度的基色,每种基色使用2bit来表示,能显示的颜色为(2^2)*(2^2)*(2^2)=64种16级(=2^4)灰度的基色,每种基色使用4bit来表示,能显示的颜色为(2^4)*(2^4)*(2^4)=4096种256级(=2^8)灰度的基色,每种基色使用8bit来表示,能显示的颜色为(2^8) *(2^8)*(2^8)=16777216种可以根据颜色的浓烈程度将三原色都分成256个级别(0-255)，则可以使用255级的红色、255级的蓝色、255级的绿色组合成白色；可以使用0级的红色、0级的蓝色、0级的绿色组合成黑色.三、TFT_LCD接口信号名称描述解释VSYNC 帧(垂直)同步信号表示一帧(屏)数据的开始HSYNC 行(水平)同步信号表示一行数据的开始HCLK 像素时钟信号表示正在传输一个像素的数据VD[23:0] 数据信号数据信号，最高可达16M 色LEND 行结束信号表示一行数据的结束VM(VDEN) 数据有效信号在数据有效周期内，该信号置1 PWREN 电源开关信号电源开关信号四、TFT_LCD时序图时序图中上半部是以行为单位的扫描图.(1)VSYNC信号有效时，表示一帧数据的开始.(2)VSPW表示VSYNC信号的脉冲宽度为(VSPW+1)个HSYNC信号周期.即(VSPW+1)行的数据无效.(3)还要再经过(VBPD+1)个HSYNC信号周期，有效的行数据才出现.因此，在VSYNC信号有效之后，总共还要经过(VSPW+1+VBPD+1) 个无效的行，然后第一个有效的行才出现(VDEN信号置位时，才是有效数据，否则视为无效数据).(4)随后连续发出(LINEVAL+1)行的有效数据.(5)最后是(VFPD+1)个无效的行.最终完整的一帧结束，紧接着是下一帧数据了.即下一个VSYNC信号.时序图中下半部是以每行中的像素为单位的扫描图.(1)HSYNC信号有效时，表示一行数据的开始.(2)HSPW表示HSYNC信号的脉冲宽度为(HSPW+1)个VCLK信号周期.即这(HSPW+1)个像素数据无效.(3)还要再经过(HBPD+1)个VCLK信号周期，有效的像素数据才出现.因此，在HSYNC信号有效之后，总共还要经过(HSPW+1+HBPD+1)个无效的像素，然后第一个有效的像素才出现(VDEN信号置位时，才是有效像素，否则视为无效像素).(4)随后连续发出(HOZVAL+1)行的有效数据.(5)最后是(HFPD+1)个无效的像素.最终完整的一行结束，紧接着是下一行数据了.即下一个HSYNC信号.【attention】通过TFT_LCD时序图可知，在工作中的显示器上，在四周看到黑色的边框.上方的黑框是因为当发出VSYNC信号时，需要经过若干行之后第一行数据才有效.下方的黑框是因为显示完所有行的数据时，VSYNC信号还没有发出，此时数据已无效.左边的黑框是因为当发出HSYNC信号时，需要经过若干像素之后第一列数据才有效.右边的黑框是因为显示完一行的数据时，显示器还没有扫描到最右边(HSYNC信号还没有发出)，这时数据已经无效.注意，显示器只会根据VSYNC、HSYNC信号来取得、显示数据，并不理会该数据是否有效，何时发出有效数据则由显卡决定.VSYNC信号出现的频率表示1s内能显示多少帧图像，称作垂直频率或场频率，这就是常说的显示器的频率.HSYNC信号出现的频率称作水平频率.有效数据的行数、列数，即分辨率，它与VSYNC、HSYNC信号之间的距离可以设置，这些工作由显卡来完成.。
