•Note 1: Input voltage exceeding the maximum value or improper operation may cause permanent damage to the device.
•Note 2: The input current should be ≥3000mA, otherwise it will lead to start-up failure or abnormal display, and a long time in an abnormal state may cause permanent damage to the device.
•Note 3: Please do not put the display in a high temperature and high humidity storage environment for a long time, the display needs to work within the limit value, otherwise it will be possible to damage the display.

EDID Sequence Parameters

If the system of the main control board can automatically identify the EDID for display, there is no need to set the relevant timing parameters additionally.
Otherwise, you can refer to the following EDID settings:

Pixel Clock	H Addressable	H Blanking	V Addressable	V Blanking	H Front Porch	H Sync Width	V Front Porch	V Sync Width	H Image Size	V Image Size	H Border	V Border
49.00	1024	288	600	24	48	96	3	10	154	86	0	0

Working With Raspberry Pi

Hardware Connection

As shown below, install the Raspberry Pi Zero on the display board.

Software Setting

Raspberry Pi OS / Ubuntu / Kali and Retropie systems are supported for Raspberry Pi.
When LCD works on these systems of Raspberry Pi, the resolution must be set manually, otherwise, it will result in incorrect display resolution and affect the experience.

1. Please download the newest image from the Official Raspberry Pi website.
2. Download the compressed file on the PC and unzip it to get the .img file.
3. Connect the TF card to the PC and use SDFormatter to format the TF card.
4. Open Win32DiskImager, choose the image prepared in the first step, and click "Write" to program the system image.
5. After programming, open the config.txt file in the root directory of the TF card and enter the following codes at the end of config.txt. Then, save and safely eject the TF card.

gpu_mem=256
hdmi_force_hotplug=1 
config_hdmi_boost=10
hdmi_group=2 
hdmi_mode=87 
hdmi_cvt 1024 600 60 6 0 0 0

6. Insert the TF card into the Raspberry Pi, power up the Raspberry Pi, wait for a few seconds normally and then it will display normally.

FAQ

Question:How does Zero-DISP-7A realize PWM dimming?

 Answer:

Rotate the 10K resistor shown below 180 degrees. Then the PWM input signal is connected to the N/C end of the rotated 10K resistor (indicated by the yellow arrow).

If you want to disable the backlight, you need to modify the 82K resistor to 68K as shown below:
