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

Embodiment Construction

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0023] The present invention discloses a point screen device, which is suitable for the display panel to be tested as a non-luminous display panel or a display panel plated with a 3D film on the surface or a display panel without FPC. The thickness of the display panel is less than or equal to 3mm, which includes A dark room 1 and a screen installation port 2 connected to the dark room 1 are arranged along the circumference of the screen. The panel 12 to be tested is partially extended into the dark room 1 through the screen installation port 2. The dark room 1 is provided with a screen for open...

Abstract

The invention discloses a screen lighting device and test equipment. The screen lighting device comprises a darkroom arranged in the circumferential direction of a screen and a screen installation opening communicated with the darkroom, a screen to be tested partially stretches into the darkroom through the screen installation opening, and an external light source used for lighting the screen partlocated in the darkroom is arranged in the darkroom. According to the invention, rapid lightening of one type of special display panels (1, the display panels cannot emit light, and 2, the display panels cannot be lighted through other elements) can be realized, and detection of various performances of the display panels is realized.

Description

Technical field [0001] The invention belongs to the technical field of screen testing, and in particular relates to a point screen device and display panel testing equipment. Background technique [0002] With the rapid development of optoelectronic technology, display panels have been widely used. The quality of the display panels determines the service life of the products. Therefore, it is an indispensable procedure to perform various performance tests on the display panels before they leave the factory. The prerequisites of all need to light up the display panel. At present, the display panels of general products (such as mobile phones, computer screens, and TV screens) have their own light source 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. complete test. [0003] For a special type of display panel (the display panel to be tested is a non-luminous display panel or a display pane...
