Problems solved by technology

[0003] For a special type of display panel (the display panel to be tested is a display panel that does not emit light or a display panel with a 3D film on the surface or a display panel without FPC), it not only cannot emit light itself, but also does not have the ability to pass through other The components are turned on and lit, and ordinary lighting equipment cannot complete the lighting of this type of display panel (it should be pointed out here that the lighting of the screen refers to: the inside of the screen is filled with light, and the lighting of the screen refers to the lighting of the screen. The surface of the screen is irradiated with light. When performing Gamma and Demura detection on the display panel, the screen must be illuminated instead of illuminated), and then the environment for panel detection has been achieved. Therefore, it is urgent to develop a special device for lighting this type display panel device

Abstract

The invention discloses a screen pointing device and testing equipment, which comprises a dark room arranged along the circumference of the screen and a screen installation opening connected with the dark room, and the screen to be tested partially extends into the dark room through the screen installation opening. The dark room is provided with an external light source for illuminating the screen part located in the dark room. The invention can realize fast lighting of a type of special display panel (1. cannot emit light by itself, and 2. does not have conduction and lighting through other components), and realizes the detection of various performances of this type of display panel.

Description

technical field [0001] The invention belongs to the technical field of screen testing, and in particular relates to a screen pointing device and display panel testing equipment. Background technique [0002] With the rapid development of optoelectronic technology, the display panel has been widely used. The quality of the display panel determines the service life of the product. Therefore, it is an indispensable procedure for the display panel to perform various performance tests before leaving the factory. The above tests All the prerequisites need to light up the display panel. At present, the display panels of general products (such as mobile phones, computer display screens, and TV screens) have their own light sources after power-on. At the same time, the display panels of some products light up after power-on through FPC or crimping PIN connection methods, and then complete test. [0003] For a special type of display panel (the display panel to be tested is a displa...
