Description

Technical Field

[0001] The present invention relates to the field of semiconductor technology, and more specifically, to a display device testing apparatus, system, method, equipment and medium. Background Art

[0002] The working life of display devices can be estimated by the method of accelerated aging under the combined effects of temperature and humidity. Under high temperature and humidity, voltage is applied to keep the display device in a state of continuous refresh. This is a harsh working method. Under high temperature, high humidity and rated electrical stress, poor quality devices will fail earlier. This method can be used to judge the manufacturing process level of display devices, and can also judge the quality of production batches. There are mainly two ways to perform accelerated aging tests on display devices.

[0003] One is to test in the terminal product, solder the display device to the terminal product for accelerated aging of the product, and then perform product performance test after accelerated aging, and infer the performance test results of the display device through the product test results. This test method is inefficient and difficult to operate, and the terminal product test will take up extra space for environmental equipment, which is not suitable for testing too many display devices.

[0004] The second is to test only the display device itself, connect multiple display devices with the same power supply circuit directly in parallel at both ends of the power supply, and perform performance and function tests on the display devices after accelerated aging to directly determine the test results of the display devices.

[0005] This method is more efficient than the first one, but it cannot determine the performance and functional status of display devices during accelerated aging, nor can it screen out failed devices in advance; it also cannot test display devices with different power supply circuits at the same time, and its compatibility is insufficient.
