Note :
1. All GND (Ground) pins should be connected together to the LCD module’s metal frame.
2. All VLCD (power input) pins should be connected together.
3. All Input levels of LVDS signals are based on the EIA 664 Standard.
4. Always all LVDS signal and clock input should be 4 channels and synchronized.
5. Specific pins (CN1 pin No. 4~8, 27, 44) are used for internal process of the LCD module manufacturing.
Leave these pins in condition that ‘No Connection’.
6. MST : MST option enable (Input), ‘L’ : Disable, ‘H’ : Enable
MST option : Left side image is applied to CN1, 1st & 2nd LVDS channel.
Right side image is applied to CN2, 3rd & 4th LVDS channel.
It should be tided up ‘L’ or ‘H’.
7. PWM_OUT : Reference signal (Output) for synchronizing Vsync and Burst frequency of inverter to avoid
wavy noise, flickering, etc.
8. ODC_EN : ODC enable (Input), ‘L’ : Disable, ‘H’ : Enable
9. FPS_DET : Frame rate detection (Input), ‘L’ : Under 50MHz, ‘H’: Over 50MHz.
It should be tided up ‘L’ or ‘H’.
