1、The common resolution and it's corresponding English abbreviation.
QVGA-320 × 240, VGA-640 × 480, SVGA-800 × 600, XGA-1024 × 768, WXGA-1366 × 768, SXGA-1280 × 1024, UXGA-1600 × 1200, HDTV-1920 × 1080
2、What's the main difference between the definition of LVDS interface and TTL interface?
A:The TTL interface form is RGB , LVDS interface form is the differential signal group, the specific as shown below:
TTL Interface: LVDS Interface：
TTL Interface: LVDS Interface：
3、LED backlight display, whether need backlight driver, how to distinguish?
A: if it need backlight driver, as Figure 1; If it do not need the backlight driver , as Figure II.It's main difference is concerning the backlight-driven display, the backlight interface requires a standard voltage and control pin.
4、 Please pay attention to the notices that the CCFL backlight display is changed into the LED backlight display.
A: 4.1, The regulation of CCFL backlight brightness is DC analog voltage regulation, it change the brightness by adjusting the voltage current of current inverter output,LED backlight is basically through the digital adjustment, that is PWM adjustment method , adjusting the duty ration to achieve brightness adjustment, the higher the duty ratio, the brighter.
4.2, If the LED backlight does not need to adjust the brightness, then the PWM pin must be connected to high level, can not be left floating.
4.2, If the LED backlight does not need to adjust the brightness, then the PWM pin must be connected to high level, can not be left floating.
5, How to confirm whether the display has flip function , 6Bit and 8Bit select function?
A: Please see the red frame position in the following picture, "4" feet to support 6 / 8Bit select function, "19" feet to support the flip function.
6,How to connect the LED backlight interface to the backlight?
A: "1" "2" feet normal power, "3" feet for the switch feet, connecting 5V is on, 0V is off, "4" feet is the backlight adjustment feet, if not adjust the backlight brightness,the feet connects high level, commonly 3.3V-5V can be.
