Description

Technical Field

[0001] This invention relates to the field of screen inspection technology, and more particularly to a screen inspection device for small and medium-sized screens. Background Technology

[0002] A screen is a visual output device in electronic devices used to display images, text, or video information. Its core function is to convert electronic signals into optical images that humans can recognize. The core materials are a glass substrate and a semiconductor thin film. The pixel structure consists of red (R), green (G), and blue (B) sub-pixels, which form the smallest display unit. Millions of colors are mixed by controlling the brightness of the sub-pixels. During the screen production process, the screen needs to be inspected to determine whether it is qualified. Physical defects such as scratches, stains, bubbles, and cracks on the screen surface are identified by visual inspection or optical instruments (such as high-precision visual inspection systems), and the size and distribution of edge chipping and burrs are evaluated.

[0003] However, in the process of developing this invention, the inventors discovered that the existing technology has at least the following unresolved problems: 1. When inspecting small and medium-sized screens, only surface defects are detected, which cannot simulate stability under different temperature environments. This makes the screen prone to explosion under thermal expansion and contraction, thus reducing safety; 2. When inspecting screens, manual comparison and recording of defect points are required. When inspecting a large number of screens, manual data recording is prone to errors, thus reducing the accuracy of the inspection data; 3. When inspecting screens, the screen's viewing effect under interfering light cannot be tested, thus reducing the comprehensiveness of screen inspection. Therefore, this invention designs a small and medium-sized screen inspection device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as: when inspecting small and medium-sized screens, only surface defects are detected, failing to simulate stability under different temperature environments. This can lead to screen explosions due to thermal expansion and contraction, reducing safety. Furthermore, manual comparison and recording of defect points is required during screen inspection, which can easily lead to errors when inspecting a large number of screens, reducing the accuracy of the inspection data. Additionally, the invention cannot test the screen's viewing effect under interfering light conditions, thus reducing the comprehensiveness of screen inspection.
