Precision Protection, Extended Vision: CNK LCD Module Usage Guide

In today's era of booming smart devices, the LCD screen, as the core window for human-machine interaction, is crucial for its performance and lifespan.

  CNK, a specialized and innovative enterprise deeply rooted in the display technology field, not only provides diversified standard LCD modules ranging from 0.96 to 15.6 inches but also offers customized LCD screen solutions tailored to your specific needs.

Precision Protection, Extended Vision: CNK LCD Module Usage Guide 1

Basic Protection: Guarding the Glass Core
The heart of every display module is its precise glass substrate and polarizer. LCD screens are extremely fragile; please always:

  • Avoid drops and impacts: Any mechanical shock may cause the glass to shatter.
  • Stay away from strong pressure and touch: Excessive pressing or direct hand contact with the screen can cause color distortion, surface contamination, or even permanent damage. The soft polarizer film covering the screen is particularly afraid of scratches from sharp objects and high temperatures.
  • Beware of leakage risk: If the LCD module is damaged causing liquid crystal material leakage, avoid contact with mouth and eyes. If skin is contaminated, wash immediately with soapy water.

Professional Cleaning & Environmental Control
Keeping the LCD screen clear and clean requires skill:

  • Gentle wiping: Use a clean, soft cloth for light stains. For stubborn stains, use a minimal amount of ethanol/isopropanol on the cloth. Avoid excess liquid or forceful rubbing.
  • Prevent corrosion: Acidic, alkaline substances, alcohol, and prolonged direct hand contact can damage the display surface. Humid environments accelerate electrode corrosion – special attention is needed!
  • Static electricity enemy: LCD modules are sensitive to static electricity. Always use grounding equipment during assembly.

Installation Specifications & Long-term Maintenance
Correct installation and usage are key to extending the life of the LCD module:

  • Avoid squeezing and deformation: Do not twist, warp, or deform the module during installation. Absolutely avoid forcibly pulling or bending FPC/backlight cables.
  • Safe power-off: When not in use for extended periods, be sure to cut off all power and perform effective grounding discharge.
  • Image rotation prevents burn-in: Avoid displaying the same image for long periods to prevent image retention (burn-in).
  • Note temperature effects: Response time, brightness, and uniformity will vary with temperature – this is normal.
  • NC pins floating: No-Connect (NC) pins must remain unconnected.

  By following these guidelines, you can maximize the performance and value of CNK's LCD modules.Let's work together to protect every inch of your clear vision!
