Abstract

The invention relates to a light leak detection device. The light leak detection device comprises a clamp unit and a detection device body. The clamp unit comprises a base. A fixing block is arranged at one end of the base, and a fixing sliding block is arranged at the other end of the base. An electronic product to be detected is installed between the fixing block and the fixing sliding block. Light blocking foam is arranged on the portion, between the fixing sliding block and the fixing block, of the base. A groove is formed in the portion, between the light blocking foam and the fixing block, of the base, and the detection device body is arranged in the groove. The arranged light blocking foam has the effect of preventing the surface of a display screen from making contact with the base in the detection process to protect the surface of the display screen and also has the effect of forming a closed space together with the fixing block to guarantee a sufficient detection light source; a plurality of sensors are arranged, an MCU control unit sends data to an external PC for calculation, and therefore the detection process is quantified.

Description

technical field [0001] The invention relates to a detection device, in particular to a light leakage detection device for detecting a display screen. Background technique [0002] With the technological development of consumer electronic products, display screens have become the most critical part of many consumer electronic products, and in order to ensure the quality of ex-factory products, the quality of display screens must be tested. The installation of the display screen is not in place, causing the screen LCD to not fit tightly with the edge of the frame, resulting in light leakage from the lamp tube, which is a relatively common problem. The structure of the current display light leakage detection device is too complicated, and the detection method lacks a quantitative method, so it is impossible to quickly test whether the display screen has light leakage through a simple device. [0003] In view of the above-mentioned defects, the designer is actively researching ...
