Linux Software Dimming

#Install ddcutil tool:
sudo apt-get install ddcutil -y
#Detect whether it supports DDC/CI monitors:
sudo ddcutil detect
#Adjust the monitor brightness, <value> needs to modified as 0-100.
sudo ddcutil setvcp 10 <value>

For more ddcutil function commands, you can refer to http://www.ddcutil.com/commands/.

Working with Horizon Sunrise X3 Pi

Support Ubuntu20.04 system.
Please download the ubuntu20.04 image from here, and then program the system according to the user manual.

How to use:
1) Connect the 12V power supply to the DC port of the LCD, and you can see the LCD backlight is on.
2) Connect the HDMI interface of the X3 Pi to the USB interface of the LCD.
3) Connect the HDMI interface of the X3 Pi to the HDMI interface of the LCD.
4) Connect the 5V power supply to the X3 Pi and power on it.

Note:

If you connect the LCD after booting X3 Pi, and there is no image on the LCD, you need to reboot the X3 Pi.

Working with PC

Support PC Windows 11/10/8.1/8.7
Usage steps:
1) Provides 12V to the DC port of the LCD and you can see its backlight is on.
2) Connect the TOUCH port of the LCD to the USB port of the PC. Please wait for seconds and Windows can automatically recognize the touch function.
3) If you want to use HDMI communication, you can use the HDMI port of the LCD to the PC, and you can see the LCD display normally after a few seconds. If you want to output the audio, you can connect 3.5mm earphones to the HP audio port.
Note:
1) When the PC is connected to multiple monitors at the same time, the cursor on the main monitor can only be controlled through the LCD, so it is recommended to set the LCD as the main monitor.
2) Some PCs do not support plug-and-play with HDMI devices. Generally, they can be used normally after restarting the system.
3) The HP audio output can be used normally only during HDMI communication.

Windows Software Dimming

  • 1. Download and install the DDC/CI application, for example, the open-source Twinkle Tray.
  • 2. Open the software dimming icon, it will recognize the Waveshare monitor and adjust the monitor backlight brightness by sliding the scroll bar.

Keys

  • Power: Turn on/off LCD. Switch the backlight power on and off. If you do not need to use the LCD for a long time, you can use this button to turn off the backlight and reduce power consumption.
  • Menu: Open OSD Menu/OK. Press the key to open the OSD menu. When using the menu, it can also be used as a confirmation button.
  • Up/Left: Direction buttons
  • Down/Right: Direction buttons
  • Exit: Return

Screen installation reference instructions

The LCD on the screen and the touchpad are bonded using double-sided tape. To prevent the LCD and touchpad from peeling off in certain special situations (such as when the screen is tilted for installation), the screen needs to be supported during installation. The following is a reference example Note: The assembly materials used below are not included in the shipped kit! ! This is only for installation reference and material reference.

Reference Drawing

15.6inch HDMI LCD assembly.jpg

Part Name:
1. Equipment case (it is recommended to use aluminum plate, or acrylic plate. If the material is acrylic plate, it can be shaped like a step as shown in the picture, or it can be split into two pieces)
2. Countersunk head machine screw
3. Copper pillar
4. Adhesive-backed sponge
5. Base plate (if it is an acrylic plate, it is recommended that the thickness is 5mm or more)
6. Round head machine screw
7. HDMI LCD
Assembly Instructions
1. Fix the copper pillar ③ to the back of the equipment case ① with the countersunk screws ②, then embed the HDMI LCD ⑦ into the equipment case ① and bond it firmly. It is recommended that the shell ① be be shaped like a step as shown in the picture, so that the TP cover plate is embedded in the case and is flush with the top surface of the case.
2. Attach an adhesive-backed sponge ④ of appropriate thickness to the acrylic plate ⑤. Pay attention to the position where it is attached to avoid the PCB board. Finally, fix it on the copper pillar ③ with round head screws ⑥, and ensure that the sponge completely fits the back of the LCD screen after assembly.
3. Holes need to be made on the base plate to avoid the components on the PCB board to facilitate the connection between the interface and the device.
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 is necessary to install at an angle, the angle between the back of the LCD screen and the horizontal direction must be at least less than 75 degrees.

 Answer:

It depends on the system, if the system has hibernation, the screen will also be black. If it is the official system of Raspberry Pi, the default is about ten minutes without action to have hibernation.


 Answer:

The 15.6inch HDMI LCD (H) (with case) is powered by two parts, one is the POWER interface, which needs to be connected to a 12V 1A power adapter, and the working current is about 12V 0.6A during normal operation.

The other is the TOUCH interface, which generally needs to be connected to the USB interface of the host. Power is drawn through the USB interface. The working current is about 5V 80mA.


 Answer:

Remove the triode shown in the figure below, and solder the PWM pin on the pad indicated by the arrow on the right.
11.6 13.3 15.6 pwm FAQ.png
Execute the following command on the Raspberry Pi terminal:

 gpio -g pwm 18 0
 gpio -g mode 18 pwm (occupied pins are PWM pins)
 gpio pwmc 1000
 gpio -g pwm 18 X (X ranges from 0 to 1024), 0 is the brightest, 1024 is the darkest


 Answer:

12V 1A outer diameter 3.5 and inner diameter 1.35. If you want to use other power supplies, you need to ensure that the power supply ripple is within ±5%
