4.1. Raspberry Pi Setup

Follow these steps to set up your display with a Raspberry Pi:

1. Prepare the TF Card: Insert the TF card containing your Raspberry Pi OS (e.g., Raspbian) image into your computer.
2. Configure `config.txt`: Navigate to the Waveshare Wiki for the 5.5-inch HDMI AMOLED display to find the necessary configuration statements. Open the `config.txt` file located in the BOOT directory of your TF card and paste the copied statements into it. This is crucial for proper display and touch functionality.
3. Assemble the Display and Raspberry Pi:
   • Screw the short standoffs onto the display's PCB.
   • Carefully align and place your Raspberry Pi onto the standoffs.
   • Secure the Raspberry Pi using the small screws provided in the standoffs pack.
   • Connect the display interfaces using the provided HDMI adapter (HDMI Adapter ②) and touch interfaces using the USB adapter (USB Adapter ②).
   • Cover the assembly with the provided 3D printed case components (Case ① and Case ③) in order, securing them with screws.
   • Install the 5V cooling fan onto the remaining case housing (Case ②) and fix it with its own screws.
   • Connect the fan to the appropriate pins on your Raspberry Pi (refer to the fan's wiring for correct polarity).
   • Finally, screw the Case ② onto the assembled unit.
4. ເປີດ: Connect the power supply to your Raspberry Pi. The display should power on and show the Raspberry Pi OS.

4.2. PC Setup (Windows)

To use the display with a Windows computer:

1. Connect the display to your computer via the HDMI and USB cables.
2. The display orientation is portrait by default (1080x1920). To change to landscape mode, open your computer's display settings.
3. In the multi-monitor setup option, choose 'extended mode' to use the display as a secondary monitor.
4. Adjust the display mode to landscape for horizontal viewing if desired.

5. ຄໍາແນະນໍາການດໍາເນີນງານ

Once connected and configured, the Waveshare 5.5-inch AMOLED display operates as a standard display with touch input. For Raspberry Pi, the touch functionality is driver-free for most supported operating systems. For Windows, the 5-point touch control is also plug-and-play.

• ການໂຕ້ຕອບການສຳຜັດ: Use your fingers to interact with the screen, similar to a smartphone or tablet. The display supports up to 5-point multi-touch, depending on the operating system.
• ສະແດງທິດທາງ: As noted, the native resolution is 1080x1920 (portrait). If you require landscape orientation, ensure you have applied the necessary software configuration as detailed in the Raspberry Pi setup section or through your computer's display settings.
• ສຽງອອກ: Connect headphones or external speakers to the 3.5mm audio jack for sound output from the HDMI source.

6. ບໍາລຸງຮັກສາ

To ensure the longevity and optimal performance of your Waveshare 5.5-inch AMOLED Display, please observe the following maintenance guidelines:

• ຈັດການດ້ວຍຄວາມລະມັດລະວັງ: The glass panel of the AMOLED display is fragile, especially without an enclosure. Always handle the display carefully, holding the PCBA (Printed Circuit Board Assembly) when plugging in HDMI or USB cables to avoid applying hard pressure to the glass panel.
• ທໍາຄວາມສະອາດ: ໃຊ້ຜ້າແພທີ່ອ່ອນໆ, ບໍ່ມີເສັ້ນດ່າງ, dampened with water or a screen-safe cleaning solution, to clean the display surface. Avoid abrasive materials or harsh chemicals.
• ການເກັບຮັກສາ: When not in use, store the display in a cool, dry place, away from direct sunlight and extreme temperatures. If possible, keep it in its original packaging or a protective case.
• ການສະຫນອງພະລັງງານ: Ensure you use a stable 5V power supply with sufficient current (e.g., 2A or 2.5A for Raspberry Pi) to prevent power-related issues like flickering or failure to power on.

7. ການແກ້ໄຂບັນຫາ

If you encounter issues with your Waveshare 5.5-inch AMOLED Display, consider the following common problems and solutions:

• Display Not Powering On / Green LED Flashing: This often indicates insufficient power. Ensure you are using a 5V power supply with adequate current (e.g., 2A or 2.5A). Check all power connections.
• No Display / Incorrect Resolution: Verify that the `config.txt` file on your Raspberry Pi's TF card has the correct configuration statements for the 1080x1920 resolution. For Windows, check display settings to ensure the correct resolution and display mode (extended/duplicate) are selected.
• Incorrect Display Orientation (Portrait/Landscape): The display is portrait by default. For landscape mode, you must change the software configuration in your Raspberry Pi's `config.txt` file or adjust display settings in Windows.
• ການສຳຜັດບໍ່ເຮັດວຽກ: Ensure the USB cable for touch input is securely connected to both the display and the host device (Raspberry Pi or PC). For Raspberry Pi, confirm that the necessary drivers or configurations are in place as per the Waveshare Wiki.
• Screen Flickering or Instability: This can be a sign of an unstable power supply or a loose connection. Check power source and all cables.
• Physical Damage (Cracks): The AMOLED glass panel is fragile. If the screen is cracked, it likely requires replacement. Handle with extreme care during assembly and use.
