When the IC is exposed operating environment beyond this range, the IC is not guaranteed for the normal operations and may be damaged permanently, not be able to be recovered. Note 2: Operating temperature means the possible range of device-operating temperature. It does not mean that the performance of the driver IC would be guaranteed over this temperature range. Note 3: Absolute maximum rating is guaranteed only when our company s package used. 4.2 Environmental Condition Item Operating temperature (Topr) Table 4 Storage temperature (Tstg) (Note 1) Remark Min.

It means undesired short pulse such as glitch, bouncing noise or electrostatic discharge do not cause irregular system reset.

14 6. Optical Characteristics The test of Optical specifications shall be measured in a dark room (ambient luminance 1 lux and temperature = 25±2 ) with the equipment of Luminance meter system (Goniometer system and TOPCONE BM-5) and test unit shall be located at an approximate distance 50cm from the LCD surface at a viewing angle of θ and Φ equal to 0. The center of the measuring spot on the Display surface shall stay fixed. The backlight should be operating for 30 minutes prior to measurement. Optimum viewing angle direction is 12 o clock. Table 8 Fig. 8 Note: 1.Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing are determined for the horizontal or 3, 9 o clock direction and the vertical or 6, 12 o clock direction with respect to the optical axis which is normal to the LCD surface (see Fig.9) 2. Contrast measurements shall be made at viewing angle of θ= 0 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 Fig. 9) Luminance Contrast Ratio (CR) is defined mathematically. P.14

15 3. Transmittance is the value with Polarizer. 4. The color chromaticity coordinates specified in Table 8 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 C/F. Measurement condition is C -light source & Halogen Lamp. 5. The electro-optical response time measurements shall be made as Fig. 10 shown in Appendix by switching the data input signal ON and OFF. The times needed for the luminance to change from 10% to 90% is Tr, and 90% to 10% is Td. Figure 8: The definition of Vth & Vsat Figure 9: Measurement Set Up Figure 10: Response Time Testing P.15
