[0002] Liquid crystal screen aging test is a quality detection process for liquid crystal display (LCD), which is used to simulate the performance changes of liquid crystal screen after long time use, so as to find potential quality problems in advance.

[0003] After long time work, the arrangement of liquid crystal molecules in the liquid crystal screen may change. Through aging test, whether the display parameters such as brightness, contrast ratio and color saturation of the liquid crystal screen can remain stable can be observed. For example, the brightness of the liquid crystal display may decrease due to the aging of the backlight source or the performance change of the liquid crystal molecules after continuous lighting for a certain time. Aging test can help determine whether this brightness decrease is within a reasonable range, so as to ensure the display quality of the product within the normal service life.

[0004] Considering the performance differences of liquid crystal screen under different temperature environments, high and low temperature aging test will be performed on the liquid crystal screen. The liquid crystal screen is placed in high temperature and continuously works in these environments.
