4. Absolute Maximum Ratings
Notes ：
1. Input voltage include REVERSE.
2. Ta means the ambient temperature.
It is necessary to limit the relative humidity to the specified temperature range.
Condensation on the module is not allowed.
3. The absolute maximum rating values of this product are not allowed to be exceeded at any times.
When exceeded the maximum ratings, the characteristics of the module may not be recovered, or
in an extreme condition, the module may be permanently destroyed.

Note ：
1 . The low level of these signals and analog powers are GND level.
2 . All of the power and signals should be kept at GND level before power on. If there are residual voltages
on
them, the LCD might not work properly.
3 . Keep backlight turned off until the display has stabilized.
4 . LED driver input signal should follow VBL→E-PWM→BLON sequence.
7. Optical Characteristics
Test Conditions:
1. The ambient temperature is 25 ℃ .
2. The test systems refer to Note1 and Note2.
Note1: Definition of optical measurement system.
The optical characteristics should be measured in dark room. After 5 Minutes operation, the optical

characteristics are measured at the center point of the LCD screen.
Measurement Set Up
Note2: Definition of viewing angle range and measurement system. Viewing angle is measured at the center
point of the LCD 。
Measurement viewing angle
Note3: Definition of contrast ratio
Note4: Definition of Response time
For SFT LCM, the response time is defined as the LCD optical switching time interval between
“ White ” state and “ Black ” state. Rise time (Tr) is the time between photo detector output
intensity changed from 10% to 90%. And fall time (Tf) is the time between photo detector output
intensity changed from 90% to 10%.
Note5: Definition of color chromaticity (CIE1931)
Color coordinates measured at center point of LCD.
Note6: Definition of Luminance Uniformity
Active area is divided into 9 measuring areas (Refer Fig.5). Every measuring point is placed at the
center of each measuring area.
Luminance Uniformity (U) = Lmin/ Lmax
Lmax: The measured Maximum luminance of all measurement position.
Lmin: The measured Minimum luminance of all measurement position.
L-------Active area length; W----- Active area width
