Why Temperature Verification Matters

For industrial applications, extreme environments can affect display performance. Temperature verification should confirm the display's operation under defined conditions.

−20°C to +70°C

Specified operating range
Use as a verified claim only after the applicable model has been tested.

1 Test Process

A representative bar LCD model is evaluated under defined low- and high-temperature conditions. Record the actual chamber/sample temperature and display status throughout the test.

1 · Test Setup

HITULCD bar LCD temperature test setup
  • Bar LCD sample
  • Power and signal source
  • Temperature logger
  • Fixture and camera

2 · Low Temperature −20°C

Low temperature chamber test for industrial bar LCD
  • Cool to target temperature
  • Confirm stability
  • Run defined signal
  • Record status and data

3 · High Temperature +70°C

High temperature chamber test for bar LCD screen
  • Heat to target temperature
  • Confirm stability
  • Run continuous signal
  • Record status and data

4 · Post-Test Inspection

Post temperature test inspection of bar LCD
  • Return to room temperature
  • Check display function
  • Inspect appearance
  • Record abnormalities
2 Test Results

Report the observed display condition at each test point. Include any black screen, flicker, image artifacts, freezing, or other abnormality.
