OPTICAL SPECIFICATION TFTLCD Products O Overview The test of Optical specifications shall be measured in a dark room (ambient luminance lux and temperature = 25±2 ) with the equipment of Luminance meter system (Goniometer system and TOPCONE BM5) and test unit shall be located at an approximate distance 5cm from the LCD surface at a viewing angle of θ and Φ equal to. We refer to θ Ø= (=θ 3 ) as the 3 o clock direction (the right ), θ Ø=9 (= θ 2 ) as the 2 o clock direction ( upward ), θ Ø=8 (= θ 9 ) as the 9 o clock direction ( left ) and θ Ø=27 (= θ 6 ) as the 6 o clock direction ( bottom ). While scanning θand/or Ø, the center of the measuring spot on the Display surface shall stay fixed. The backlight should be operating for 3 minutes prior to measurement... VDD shall be 3.3+/.3V at 25 C. Optimum viewing angle direction is 6 o clock. 4.2 Optical Specifications <Table 4. Optical Specifications> Parameter Symbol Condition Min. Typ. Max.

9 TFTLCD Products O Note :. Viewing angle is the angle at which the contrast ratio is greater than. The viewing are determined for the horizontal or 3, 9 o clock direction and the vertical or 6, 2 o clock direction with respect to the optical axis which is normal to the LCD surface (see FIGURE shown in Appendix). 2. Contrast measurements shall be made at viewing angle of Θ= and at the center of the LCD surface. Luminance shall be measured with all pixels in the view field set first to white, then to the dark (black) state. (See FIGURE shown in Appendix) Luminance Contrast Ratio (CR) is defined mathematically. CR = Luminance when displaying a white raster Luminance when displaying a black raster 3. Center Luminance of white is defined as luminance values of 5 point average across the LCD surface. Luminance shall be measured with all pixels in the view field set first to white. This measurement shall be taken at the locations shown in FIGURE 2 for a total of the measurements per display. 4. The White luminance uniformity on LCD surface is then expressed as : ΔY = Minimum Luminance of 5(or 3) points / Maximum Luminance of 5(or 3) points (see FIGURE 2 shown in Appendix). 5. The color chromaticity coordinates specified in Table 4 shall be calculated from the spectral data measured with all pixels first in red, green, blue and white. Measurements shall be made at the center of the panel. 6. The electrooptical response time measurements shall be made as FIGURE 3 shown in Appendix by switching the data input signal ON and OFF. The times needed for the luminance to change from % to 9% is Tr, and 9% to % is Td. 7. CrossTalk of one area of the LCD surface by another shall be measured by comparing the luminance (Y A ) of a 25mm diameter area, with all display pixels set to a gray level, to the luminance (Y B ) of that same area when any adjacent area is driven dark. (See FIGURE 4 shown in Appendix). S HT2 Product Specification 9 OF 26 B25CO(3/3) A4(2 297)

19 TFTLCD Products O HANDLING & CAUTIONS 2. Cautions when taking out the module Pick the pouch only, when taking out module from a shipping package. 2.2 Cautions for handling the module As the electrostatic discharges may break the LCD module, handle the LCD module with care. Peel a protection sheet off from the LCD panel surface as slowly as possible. As the LCD panel and backlight element are made from fragile glass material, impulse and pressure to the LCD module should be avoided. As the surface of the polarizer is very soft and easily scratched, use a soft dry cloth without chemicals for cleaning. Do not pull the interface connector in or out while the LCD module is operating. Put the module display side down on a flat horizontal plane. Handle connectors and cables with care. 2.3 Cautions for the operation When the module is operating, do not lose MCLK, DE signals. If any one of these signals were lost, the LCD panel would be damaged. Obey the supply voltage sequence. If wrong sequence were applied, the module would be damaged. 2.4 Cautions for the atmosphere Dewdrop atmosphere should be avoided. Do not store and/or operate the LCD module in a high temperature and/or humidity atmosphere. Storage in an electroconductive polymerpacking pouch and under relatively low temperature atmosphere is recommended. 2.5 Cautions for the module characteristics Do not apply fixed pattern data signal to the LCD module at product aging. Applying fixed pattern for a long time may cause image sticking. 2.6 Other cautions Do not disassemble and/or reassemble LCD module. Do not readjust variable resistor or switch etc. When returning the module for repair or etc, please pack the module not to be broken. We recommend using the original shipping packages.
