This driver board is an LVDS-single 6BIT or 8BIT signal input (use as required), LVDS signal pass-through output 40PIN universal definition signal output, and integrated LED backlight driver (200-1200 brightness adjustable), VCOM voltage can Potentiometer (adjustable), LCD screen adapter board that can generate multiple voltages such as AVDD, VGL, VGH, VCOM, etc.
2. This driver board can support EJ070NA-01J,
EJ080NA-04B
EJ080NA-04C
EJ101NA-01
etc., a universal 40PIN LCD screen, or a defined LCD screen with the same function (you can also consult our company's technical department)
3. This driver board uses the standard DF14-20P interface for LVDS signal input. It is recommended to use an 8BIT signal line.
4.
6BIT, PIN16 needs to be connected to high level or VCC
8BIT signal PIN16 needs to be grounded.
Please choose different settings according to the actual situation of your motherboard.
5. If the current backlight cannot meet the brightness requirements, you can refer to the following technical instructions and set it yourself.
6. This driver board and capacitor components are of Samsung brand, and the working temperature can reach -50 degrees to 120 degrees.
7. This driver board and resistor components are made of Taiwan's H&S brand, and the working temperature can reach -50 degrees to 120 degrees.
8. The comprehensive operating temperature of this driver board can range from -20 degrees to +70 degrees.
For other related technical questions, please consult our company’s technical department
In addition, the thickness of this driver board has been adjusted throughout the line, with a minimum thickness of 5.3MM, and all chip components.
2 Feature Description
Input signal LVDS support mode
6BIT or 8BIT needs to set the voltage or ground of PIN16 as required.
Interface Standard LVDS signal interface DF14-20P
Screen interface 40PIN-0.5MM standard EJ080NA-04C definition
INVERTER interface
6PIN standard socket (for interface definition, please refer to the relevant instructions in the product specifications below)
Please pay special attention to the fact that the backlight part needs to be powered separately, with a power supply voltage of 5V and a circuit of no less than 1A. Otherwise, the ideal brightness may not be achieved. Please pay special attention.
Power input power supply: 3.3V power supply on the same screen (no additional settings required)
Special note, very important: Supports LED backlight drive LCD screen backlight voltage between 8V-37V, maximum current is about 360MA

6 Transportation, storage and usage requirements
1. Do not apply heavy pressure or bend deformation.
2. Anti-static and water resistant
3. Relative humidity, less than 80%
4. Operating temperature -1-degree--+60 degree
5. Use humidity 0-+40 degrees
When setting up the technical functions of the driver board, please read the following instructions carefully, and when making technical improvements, pay attention to correct operations to avoid damaging the driver board or LCD screen.
1. Signal input settings of 6BIT-8BIT
Control principle, this setting is to control the high and low levels of 28PIN of the LCD screen to complete the signal input identification setting. Since this driver board directly leads to the 16th PIN of the LVDS-20PIN screen line, you need to make the following settings according to your own needs.
LVDS signal input type PIN16 Remarks
6BIT 3.3V can be connected to the screen power supply pin. This type needs to be improved as required.
8BIT 0V groundable wire This type needs to be improved as required
2. Relevant instructions on backlight input and switch control parts, and screen power supply
Backlight power supply type R78 Remarks
5V is currently 0.68R. The smaller the resistance, the greater the output current, otherwise the opposite is true.
3. The backlight defaults to 3.3V and is powered by the screen voltage. If the backlight brightness is not enough, you can remove R33 and use the backlight holder to supply 5V voltage to obtain greater current and better brightness.
Backlight power supply type R33 must be removed when the power supply is 5V. The default power supply is 3.3V.
5V is currently 0.68R. The smaller the resistance, the greater the output current, otherwise the opposite is true.
4. The backlight power supply must not be greater than 15V, otherwise the backlight driver IC or LCD screen may be damaged.
5. The backlight switching signal must not be greater than 5V, otherwise the backlight driver IC may be damaged.
