Screen detecting device

Abstract

The invention relates to the technical field of screen detection, and in particular to a screen detecting device. The device includes a support platform, a support base disposed on the support platform, a carrying seat disposed on the support base, an illumination mechanism, a probe assemblyand an information collection mechanism; the illuminating mechanism is located under the carrying seat, andthe illuminating mechanism is disposed on the support platform; the probe assembly is located above the carrying seat, the probe assembly is movable up and down, the probe assembly comprises a cantilever probe carrier plate and cantilever probes, and each cantilever probe is disposed at the cantilever probe carrier plate; the information collection mechanism is located above the carrying seat, andthe information collection mechanism can collect information on a screen. The cantilever probes on the cantilever probe carrier plate are in contact with the screen on the carrying seat, and abuts ona detection point on the screen, the two cantilever probes are turned on, the illumination mechanism emits laser light on the screen,the information collection mechanism collects light passing through the screen, and image information is analyzed to determine the uniformity and stability of screen imaging.

Description

technical field [0001] The invention relates to the technical field of screen detection, in particular to a screen detection device. Background technique [0002] With the continuous development of information technology, screen display systems have been widely used in communication, education, transportation, studios and other places, and play an important role in providing shared information, decision support, and situation display. During the use of the screen, users are eager to obtain good display effects such as high resolution and high brightness, and the performance of the screen will affect the display effect of the display unit. Generally, the optical parameters of the screen need to be checked before the screen is put into use. . [0003] Traditionally, two methods are used to solve the problem. One is to directly install the incoming materials of the screen on the system wall, and then replace the screen if any problem is found; the other is to use a handheld te...

AI Technical Summary

Problems solved by technology

However, the defective rate of the viewing angle difference of screen incoming materials is about 10%-20%. Using the above-mentioned detection method lacks comprehensive and efficient detection methods, and the handheld detection method has poor positioning accuracy, low efficiency, and large inspection errors, which leads to back-end It was found that the performance of the optical machine and the screen was poor, resulting in a waste of manpower and material resources and an increase in product costs
