The ThermoTST TS series high and low temperature tester of Chengdu Chinacryo Technology can be used with the LCD measurement system to test the LED ambient temperature. Each DMS system can be extended with an appropriate hot and cold system for temperature related measurement of optical display characteristics and conformance testing.

Reasons for environmental temperature test of LED LCD: the operating temperature of LCD is generally 20-50 degrees, and there are many heating electronic components inside the LCD. To ensure the normal operation of electronic components in low temperature and high temperature extreme environments, manufacturers need to conduct LED environmental test before leaving the factory. The main test items include thermal cycle of cold and hot cycles and thermal shock of cold and hot cycles.

Customer case of LED LCD: The customer, an internationally renowned display manufacturer, purchased TS-780H for high and low temperature testing of display according to actual production needs. TS-780H mobile design, test temperature - 55 ° C to+125 ° C, intuitive operation.

TS-780H DUT mode test

1. Directly connect the high and low temperature tester TS-780H with the LCD system through the pipeline.

2. The operator sets the temperature range to be tested.

3. Start TS-780H and use the air compressor to introduce dry and clean air into the refrigerator for low-temperature treatment, and then the air will reach the heating head through the external pipeline for temperature rise.

4. The high and low temperature tester TS-780H display screen can monitor the current circulating impinging airflow temperature in real time, and has its own overheating temperature protection system. The factory set temperature is+225 ° C. The operator can set the high and low temperature limit points according to actual needs. When the temperature reaches the set temperature, the tester will automatically stop.
