Pre-Installation Testing Guide for LCD Screen Panel Only

Handle with Care

1. Fragility Warning:

•  The LCD screen panel is a delicate component. Avoid applying pressure, twisting, or touching the exposed edges.
• Do not remove protective films or labels during testing. These protect the screen from scratches and static damage.

2. Static Safety:

• Work in a static-safe environment. Use an anti-static wrist strap or mat to prevent electrostatic discharge (ESD).
• Avoid wearing synthetic clothing or working on carpets.

Testing Procedure

 Step 1: Prepare the Test Setup

• Ensure you have a compatible flex cable (not included with the panel).
• Gently connect the LCD panel’s flex cable to a test device’s motherboard connector.

Note: Align the cable correctly to avoid misalignment damage.

 Step 2: Power On & Test Functionality

• Power on the test device and check for:
      Brightness: Ensure uniform backlight with no dark spots.
      Color Accuracy: Verify no discoloration, dead pixels, or uneven color gradients.
      Touch Response (if applicable): Test touch sensitivity across the entire screen.

Test Results:

If the LCD works properly: Proceed with installation. Handle the panel by its edges only.

If the screen fails (no display, flickering, or defects): Stop immediately. Do not attempt installation.  Contact our support team with photos/videos of the issue for troubleshooting or replacement.

Warning:

• Flex Cable Handling: 
  Never bend the flex cable beyond 90 degrees. Excessive bending can cause permanent damage (e.g., black screens, vertical lines).
  Ensure the cable lies flat and is not pinched during installation.
  
  
• Installation Environment:
  Work in a clean, dust-free area to prevent debris from entering the screen or connectors.
  
  
• No Forced Connections:
  If the flex cable resists insertion, recheck alignment. Forcing it may damage the connector pins.
