Contrast Ratio (CR) = L63 / L0 L63: Luminance of gray level 63 L0: Luminance of gray level 0 CR = CR (10) CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note 5. Note 2: Definition of Response Time (TR, TF): Figure 3 Note 3: Viewing Angle Figure 4 FS-K70DWN2-V1-FF 06/Jul 2010 PAGE 10 OF 13 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 10.1.1. The LCD screen is made of glass. Don't give excessive external shock, or drop from a high place. 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. FS-K70DWN2-V1-FF 06/Jul 2010 PAGE 12 OF 13 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 modifications with a soldering iron. 10.1.14. Do not drop, bend or twist LCM. FS-K70DWN2-V1-FF 06/Jul 2010 PAGE 13 OF 13 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 wrong operating. The dimension of the buffer material’ s edge between the TP V.A. edge is Min. 0.3mm. 10.2.2. We recommend to design a case that it can’t over the boundary of the active area Max. 0.5mm in order to prevent an operation at outside of the active area which can’t guarantee the specified durability, because operation at the outside of the active area cause serious damage of a transparent. 10.2.3. When design case for installing Module, you would consider give a distance about 0.2±0.15mm 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. 机壳 触摸屏 缓冲材料 垫圈 绝缘油墨区域 背光 驱动区域边缘 可视区域边缘 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 -
