Definition of contrast ratio** Contrast ratio(Cr) is defined mathematically by the following formula. For more information see FIG.2. Luminance with all pixels white Contrast ratio= Luminance with all pixels black For contrast ratio, Surface Luminance, Luminance uniformity and CIE,the testing data is base on TOPCON’s BM-5 or BM-7 photo detector or compatible. ## **Note2. Definition of surface luminance.** Surface luminance is the luminance with all pixels displaying white. For more information see FIG.2. Lv = Average Surface Luminance with all white pixels(P1,P2,P3, ......,Pn) ## **Note3. Definition of luminance uniformity** The luminance uniformity in surface luminance is determined by measuring luminance at each test position 1 through n, and then dividing the maximum luminance of n points luminance by minimum luminance of n points luminance.For more information see FIG.2. YU= Minimum surface luminance with all white pixels (P1,P2,P3,......,Pn) Page 11 of 21 Maximum surface luminance with all white pixels (P1,P2,P3,......,Pn) ## **Note4. Definition of response time** The response time is defined as the LCD optical switching time interval between “White” state and “Black”state.Rise time (Tr) is the time between photo detector output intensity changed from 90% to 10%. And fall time (Tf) is the time between photo detector output intensity changed from 10% to 90%. For additional information see FIG1. ## **Note5. Definition of color chromaticity (CIE1931)** CIE (x,y) chromaticity,The x,y value is determined by screen active area center position P5.For more information see FIG.2. ## **Note6. Definition of viewing angle** Viewing angle is the angle at which the contrast ratio is greater than 10. 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 FIG.3. For viewing angle and response time testing, the testing data is base on Autronic-Melchers’s ConoScope or DMS series Instruments or compatible. ## **FIG.1.The definition of response Time** ## **FIG.2.

The distance between two bright dot defects (red, green, blue, and white) should be larger than 15mm. - 3). The distance between black dot defects or black and bright dot defects should be more than 5mm apart. - 4). Polarizer bubble is defined as the bubble appears on active display area. The defect of polarizer bubble shall be ignored if the polarizer bubble appears on the outside of active display area. ## **Mechanics specification** As for the outside dimension, weight of the modules, please refer to product specification For more details Page 20 of 21 ## **Precautions for Use of LCD modules** ## **Handling Precautions** - 1.1. The display panel is made of glass. Do not subject it to a mechanical shock by dropping it - from a high place, etc. 1.2. If the display panel is damaged and the liquid crystal substance inside it leaks out, be sure not to get any in your mouth, if the substance comes into contact with your skin or clothes, promptly wash it off using soap and water. - 1.3. Do not apply excessive force to the display surface or the adjoining areas since this may - cause the color tone to vary. 1.4. The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer carefully. 1.5. If the display surface is contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If still not completely clear, moisten cloth with one of the following solvents: - － Isopropyl alcohol - － Ethyl alcohol Solvents other than those mentioned above may damage the polarizer. Especially, do not use the following: - － Water - － Ketene - － Aromatic solvents - 1.6. Do not attempt to disassemble the LCD Module. - 1.7. If the logic circuit power is off, do not apply the input signals. - 1.8. To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment. - 1.8.1. Be sure to ground the body when handling the LCD Modules. - 1.8.2. Tools required for assembly, such as soldering irons, must be properly ground. - 1.8.3.
