Application Description

HDMI TO LVDS Cable

Screen Power Output

Screen Power Modification

Overview

• HDMI input to TTL RGB or LVDS output. The definition of the socket pin signal can be found in the characters on the back of the board.

• Note: This board does not have a scaling function, so if you want to use LVDS output to display the screen, the HDMI signal resolution must be consistent with the screen parameters; if you want to use RGB output to display the screen directly, you cannot display the screen directly. Usually, you need to provide VGH, VGL, AVDD, and VCOM to display the RGB screen.

Features

• Suitable for converting HDMI input signals to TTL RGB or LVDS outputs, with a maximum bandwidth of 340MHz;
• HDMI input supports multiple resolutions such as 720P, 1080P, 4K@30, etc. - See user manual section "d) HDMI Built-in EDID Preferred Resolution Modification Command";
• Built-in EDID data, the preferred resolution can be set through the serial port;
• The output can be selected as RGB or LVDS through the serial port or on-board resistors;
• With backlight control, when the output is LVDS signal, the screen can be directly clicked;
• With 3.5mm headphone output, analog stereo output can be output;
• DC12V power supply, the board power consumption is less than 1.5W;
• HDCP is not supported.

Packing List

• 1 x HDMI to RGB/LVDS adapter

FAQ

Q: What is the maximum resolution supported by the LVDS output when using a single-port LVDS LCD panel?

A: The maximum resolution supported by the LVDS output when using a single-port LVDS LCD panel is 1080P/60fps.

Q: Is it possible to use a microcontroller to configure the output mode and resolution by sending UART commands, instead of using the UI software as described in the documentation?

A: Yes. It is supported!

Is it possible to configure the LVDS bit-depth by sending UART commands? It is set to 8-bit, but I'd like to change it to 6-bit.

Hi there! Please kindly refer to User Manual （https://wiki....1-EN.pdf） Page 6 - section "f) LVDS 6bit/8bit Output Mode Setting Command" for details.

LVDS 6bit/8bit Output Mode Setting Command

Input: test 103 id

Click "Send Data". The command is successful if the receive window displays the following. Reboot the board afterward:

cmd=103, p0=0, p1=0, p2=0

bit mode id=0x00, please re-start the board.

Note: Parameter "id" only accepts values 0 or 255.

0 = LVDS 6bit mode

255 = LVDS 8bit mode

The default LVDS output mode is 8bit
