The above “Viewing Angle” is the measuring position with Largest Contrast Ratio; not for good image quality. View Direction for good image quality is 6 O’clock. Module maker can increase the “Viewing Angle” by applying Wide View Film. Note 4: Measurement Set-Up: The LCD module should be stabilized at a given temperature for 20 minutes to avoid abrupt temperature change during measuring. In order to stabilize the luminance, the measurement should be executed after lighting Backlight for 20 minutes in a windless room. Figure 5 8.

- Suggestions for using LCD modules
10.1 Handling of LCM
10.1.2. If the LCD screen is damaged and the liquid crystal leaks out, do not lick and swallow. When the liquid is attach to your hand, skin, cloth etc, wash it off by using soap and water thoroughly and immediately.
10.1.3. Don't apply excessive force on the surface of the LCM. 10.1.4. If the surface is contaminated ,clean it with soft cloth. If the LCM is severely contaminated , use Isopropyl alcohol/Ethyl alcohol to clean. Other solvents may damage the polarizer . The following solvents is especially prohibited: water , ketone Aromatic solvents etc. 10.1.5. Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets, moisture condensation or a current flow in a high-humidity environment. 10.1.6. Install the LCD Module by using the mounting holes. When mounting the LCD module make sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O cable or the backlight cable. 10.1.7. Don’t disassemble the LCM. 10.1.8. To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment. - Be sure to ground the body when handling the LCD modules. - Tools required for assembling, such as soldering irons, must be properly grounded. - To reduce the amount of static electricity generated, do not conduct assembling and other work under dry conditions. - The LCD module is coated with a film to protect the display surface. Exercise care when peeling off this protective film since static electricity may be generated. 10.1.9. Do not alter, modify or change the the shape of the tab on the metal frame. 10.1.10. Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to be attached. 10.1.11. Do not damage or modify the pattern writing on the printed circuit board. 10.1.12. Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal connector 10.1.13. Except for soldering the interface, do not make any alterations or modifi cations with a soldering iron. 10.1.14. Do not drop, bend or twist LCM.
10.2 Cautions for installing and assemably if the module with Touch Panel
10.2.1. Use a buffer material (Gasket) between the touch panel and Front -case to protect damage and order to prevent an operation at outside of the active area wh ich can’t guarantee the specified durability, because operation at the outside of the active area cause serious damage of a transparent. between the module edge to case inside. 10.2.4. The corners of the product are not chamfered. When positioning and fixing the product on the case, we sugguest that you would provide a R part on the conner of the case so as not to apply load on the corner of the transparent module. 驱动区域边缘 可视区域边缘 背光 绝缘油墨区域 缓冲材料 垫圈 机壳 触摸屏
10.3 Storage
10.3.1. Store in an ambient temperature of 5 to 45 °C, and in a relative humidity of 40% to 60%. Don't expose to sunlight or fluorescent light. 10.3.2. Storage in a clean environment, free from dust, active gas, and solvent. 10.3.3. Store in antistatic container. - END -
