[Note]
1) DATA is latched at fall edge of DCLK in this timing specification.
2) Polarities of HD and VD are negative in this specification.
3) DENA (Data Enable) should always be positive polarity as shown in the timing specification.
4) DCLK should appear during all invalid period, and HD should appear during invalid period of frame cycle.
5) Accepted only 640 data and 480 lines.
6) REV should be stable during operation.

Conditions for Measuring
Environment: Dark room with no light or close to no light.
Temperature: 25±5°C
Humidity: 40∼70%RH
After backlight has been lit more then 30 minutes, driving voltage is set for optimal
contrast to measure center of display.
Measure by the specified inverter or similar product.
Condition: IL=6.0 mA, FL=58 kHz
