3.2英寸TFT液晶显示屏

General Deion
LCD is a 240*320 dots matrix TFT LCD module. It has a TFT panel composed of 720 sources and 320gates. The LCM can be easily accessed by micro-controller.
Backlight Characteristic

★ 1Test condition is:
(a) Center point on active area.
(b)Best Contrast.
★2Uniform measure condition:
(1)Measure 9 point. Measure location show below;
(2)Uniform=(Min. brightness /Max. brightness)*100%
(3)Best Contrast.
8.2Timing characteristics.
I80-System Interface Timing Characteristics
NormalWrote Mode(IOVCC=1.65~3.3V,Vcc=2.4~3.3V)
Reset Timing Characteristics(VCC=1.8~3.3V.IOVCC=1.65~3.3V)

9.Electro-optical Characteristics

The above “viewing angle” is the measuring position with the largest contrast ratio. Not for good image
quality. Viewing direction for good image quality is 12 O’clock.

10. Reliability
10.1Mtbf
The LCD module shall be designed to meet a minimum MTBF value of 50000 hours with normal
1. Judgments should be made after exposure in room temperature for two hours.
2. The distill water is used for the high temperature/humidity test.
3. The sample above is individually for every reliability tests condition.
11.Inspection standards
1.AQL(Acceptable Quality Level
2. Basic conditions for inspection
The LCM face to us, in normal environment, the lux is 1000±200.(Darkroom’s lux: 100±50),About an
angle of incidence 30,a distance of 30 cm with an angle of 45 degree to check the products without
uncovering the film!
3.Inspection item and criteria
3.1 Visual inspection criterion in immobility
3.1.1Glass defect
3.1.2LCD appearance defect(View area)
