4. ABSOLUTE MAXIMUM RATINGS
Item Symbol Min. Max. Unit Remarks
Supply Voltage VDD 0 4.0 V -
Input Voltage of Logic VI -0.3 VDD+0.3 V Note 1
$
Operating Temperature Top -30 80 C Note 2
$
Storage Temperature Tst -40 90 C Note 2
Backlight Input Voltage VLED - 15 V Note 3
Note 1: It shall be applied to pixel data signal, clock signal and control Pin.
Note 2: The maximum rating is defined as above based on the temperature on the panel surface, which
might be different from ambient temperature after assembling the panel into the application.
Moreover, some temperature-related phenomenon as below needed to be noticed:
- Background color, contrast and response time would be different in temperatures other than
25 $ C .
- Operating under high temperature will shorten LED lifetime.
Note 3: Do not operate at or near the maximum rating listed for extended periods of time. Exposure to
such conditions may adversely impact product reliability and result in failures not covered by
warranty.
