Description

Technical Field

[0001] This utility model relates to the field of display screen sunlight environment irradiation testing technology, and in particular to a display screen aging test system for conducting light interference and irradiation in a simulated sunlight test environment. Background Technology

[0002] Many LED and LCD displays require sunlight for experiments such as light interference, weather resistance, and temperature rise testing. In practical applications, sunlight is not stable enough to withstand varying weather conditions, necessitating adjustments to testing methods. Most commercially available sunlight simulators offer fixed directions and irradiance, and their illumination area is insufficient. Even those with larger illumination areas often lack the ability to adjust the angle of illumination, failing to accommodate all-weather light intensity variations. Consequently, LED and LCD displays are often only tested under weather conditions or at a single angle.

[0003] In addition, the light intensity detection within the illuminated surface is mostly done manually, which requires wearing protective clothing and is very inconvenient. The effective illuminated area and light intensity within the illuminated area cannot be self-checked, and the experimental preparation time is very long, which limits the application of various solar illumination effects testing of the display screen.

[0004] Therefore, there is an urgent need for an improved technology to address the shortcomings of existing technologies, such as detection time varying with the weather, limited adjustment of large-area illumination angles, long calibration and detection time before illumination experiments, and the inability to complete the detection of displays in a real-time, simple, and efficient manner.
