The 70H-1024600 series display, designed by Waveshare Team, is for customers who need a lightweight HDMI display. As it is thinner and lighter than any traditional HDMI display, users can do the second development by themselves easily.
For simplifying the display, we integrate the power supply, display, touch, and control signal as the 40PIN multi-functional header. Just need an FPC cable, you can lower the project cost with the thinnest display, and apply it in any embedded projects.
- 7-inch IPS/QLED screen, 1024 x 600 hardware resolution.
- Capacitive touch, support five-point touch (this function is only for the touch version).
- COF thin and light structure, providing 40PIN interface one-line communication, integrated development is more convenient.
- High compatibility, when used with development accessories, it supports main control boards such as Raspberry Pi, PC, and Jetson nano.
- Support backlight control, more power saving.

Adapter Board Design
You can refer to adapter board schematic to integrate the display, please note:
- HDMI needs to use an equal-length differential cable, and the differential impedance of the four pairs of differential signals needs to be controlled at 100Ω±10%.
- The four-pair differential signal cables of HDMI are required to be less than 5 inches.
- The length deviation within the HDMI differential pair is required to be controlled within 20mil, and the maximum shall not exceed 25mil.
- The interface ESD device needs to be placed close to the HDMI socket.
- The 5V power input line needs a wide enough path, it is recommended to exceed 30mil to ensure that the voltage input will not have an excessive loss.
- Pay attention to the line and direction to prevent reverse connection.
NOTE: The assembly materials used below are not included in the shipped kit! ! This is only for reference.
3D Print Shell Solution
1. The front panel comes with adhesive backing
3. Adhesive foam
4. Rear case
Affix the back of the display screen (part 2) with a suitable thickness of adhesive foam (part 3), then directly embed the display screen (part 2) into the rear case (part 4), and then paste the front panel (part 1) to the corresponding location.
How to Fix the Acrylic
1. Front panel (1.5mm thick acrylic board is recommended)
3. Adhesive foam
4. Medium plate (It is recommended to use an acrylic plate with a thickness of more than 3.5mm)
5. Bottom plate (It is recommended to use an acrylic plate with a thickness of more than 2mm)
7. Pan head screws
Align the front panel (part 1) and the midplane (part 4) and thread the screws (part 7) into the display (part 2) Paste a suitable thickness of adhesive foam (part 3) on the back of the display screen, then install the bottom plate (part 5), and finally lock the nut (part 6).
Note: The LCD display surface cannot be installed parallel to the ground, otherwise it will fall off under the action of gravity. In addition, when it needs to be installed at an angle, the back of the LCD screen should keep at least an angle of less than 75 degrees with the horizontal direction.

Working with PC
- Support Windows 11/10/8.1/8/7 system. Instructions:
- Use the FPC-Cable-15cm to connect the 70H-1024600 display screen to the development accessories (pay attention to the cable direction, 1 to 1, 40 to 40 serial number connection).
- Connect the Display interface to the PC HDMI interface.
- Connect the Touch interface to the USB interface of the PC.
- Hardware Connection:
- Some PCs do not support plug-and-play with HDMI devices. Generally, they can be used normally after restarting the system.
- Insufficient power supply of the USB interface of some PCs will cause the LCD screen to flicker, which can be restored to normal use after connecting to an external 5V/1A power supply.
PWM Light Adjustment
Connect the GND of the microcontroller (such as a potentiometer) to the GND pin in the figure below, and connect the voltage output terminal (DC 0~3.3V) of the microcontroller to the PWM pin as shown in the figure below so as to control the backlight brightness by changing the voltage.
Note: DC 3.3V is the darkest and 0V is the brightest.
Working with Raspberry Pi
- Use the FPC-Cable-15cm to connect the 70H-1024600 touch screen to the Demo board (pay attention to the cable direction, 1 to 1, 40 to 40 serial number connection).
- Connect the Display port to the Raspberry Pi HDMI port.
- Connect the Touch port to the USB port of the Raspberry Pi.
- Support Raspberry Pi OS / Ubuntu / Kali and Retropie systems.When the LCD works on systems such as Raspberry Pi, the resolution must be set manually, otherwise, the display resolution will be incorrect and the experience will be affected.
1. Please download the latest version of the image from Raspberry Pi official website.
2. Download the compressed file to the PC and extract it to get the .img file.
3. Connect the TF card to the PC, use the SDFormatter software to format the TF card.
4. Open the Win32DiskImager software, select the system image prepared in step 1, and click write to burn the system image.
5. After the programming is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, save and safely eject the TF card.
hdmi_group=2 hdmi_mode=87 hdmi_cvt 1024 600 60 6 0 0 0 hdmi_drive=1
6. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for a few seconds to display normally.
PWM Software Light Adjustment
- Raspberry Pi bullseye system with development accessories as an example.
- Hardware connection: Connect the PWM pin of the development accessory to the P1 pin of the Raspberry Pi (as shown in the figure below) and the GND pin to any GND of the Raspberry Pi.
- On Software:
Upgrade the Wiring Pi:
wget https://project-downloads.drogon.net/wiringpi-latest.deb sudo dpkg -i wiringpi-latest.deb gpio -v # Run gpio -v and version 2.52 will appear. If it does not appear, the installation is wrong.
After the wiringPi is updated successfully, the backlight brightness can be controlled by the following commands.
gpio -g mode 18 pwm #Occupied pins are PWM pins gpio pwmc 100 gpio -g pwm 18 0 #brightest gpio -g pwm 18 1023 #darkest gpio -g mode 18 out #Release as output
HDMI Apater Board Dimensions
- People who handle this module should connect the display to the ground by appropriate means, and the protective film must be removed from the LCD surface very slowly to prevent static electricity from occurring.
- Do not plug or unplug the display while the power is on, otherwise the display board or main control board may be damaged.
- Please refer to the electrical parameter description to make the display screen work within the limited value range, otherwise the display screen may be damaged.
- Do not disassemble the display, as this may damage the sensitive parts inside and may cause scratches or dust on the display. Removing the display will void the warranty.
- Please do not store the display in a high temperature and high humidity environment for a long time.
- Do not touch or rub the surface of the display with anything harder than HB pencil lead.
- If the LCD is damaged, do not swallow or inhale the liquid crystal, and do not touch the liquid crystal with your skin; if the liquid crystal touches your mouth or eyes, rinse it off with water immediately; if the liquid crystal touches your skin or cloth, rinse it off with alcohol immediately, then rinse thoroughly with water; handle glass shards with care to avoid injury.
