Product Specification
1. General Description
The LC320EXJ is a Color Active Matrix Liquid Crystal Display with an integral the Source PCB and Gate
implanted on Panel (GIP). The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally black mode. It has a 31.5 inch diagonally measured
active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7M(6bit + A-FRC) colors.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important
important.

3. Gravity mura can be guaranteed below 40 condition.
4. The maximum operating temperature is based on the test condition that the surface temperature
of display area is less than or equal to 68 with LCD module alone in a temperature controlled
chamber. Thermal management should be considered in final product design to prevent the surface
temperature of display area from being over 68 . The range of operating temperature may
degrade in case of improper thermal management in final product design.

2. If T2 is satisfied with specification after removing LVDS Cable, there is no problem.
3. The T3 / T4 is recommended value, the case when failed to meet a minimum specification,
abnormal display would be shown. There is no reliability problem.
4. T5 should be measured after the Module has been fully discharged between power off and on period.
5. If the on time of signals (Interface signal and user control signals) precedes the on time of Power (VLCD),
it will be happened abnormal display. When T6 is NC status, T6 doesn't need to be measured.
6. If there is no abnormal display, no problem.
7. It is recommendation specification that T8 has to be 100ms as a minimum value.
Please avoid floating state of interface signal at invalid period.
When the power supply for LCD (VLCD) is off, be sure to pull down the valid and invalid data to 0V.

Note : 1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
It is measured at center 1-point.
. Surface luminance is determined after the unit has been `ON' and 1Hour after lighting the
backlight in a dark environment at 25 2 C. Surface luminance is the luminance value at center
1-point across the LCD surface 50cm from the surface with all pixels displaying white.
For more information see the FIG. 1.
2. Response time is the time required for the display to transit from any g y to white (
y y gray (Rise Time, TrR)
and from any gray to black (Decay time, TrD). For additional information see the FIG. 2.
G to GBW Spec stands for average value of all measured points.
