Display panel processing device and method, display panel and controller

Abstract

The invention relates to a processing device and method of a display panel, the display panel and a controller. The device comprises a laser used for generating and emitting a laser beam; the scanning galvanometer is used for driving the laser beams to carry out scanning processing; the controller is electrically connected with the laser device and the scanning galvanometer and used for determining the arrangement mode of light spots of the laser beams in a to-be-machined area according to structural information of the to-be-machined area of the display panel and the size of the light spots of the laser beams, obtaining the target position of the laser beams in the machining process according to the arrangement mode and sending the target position to the display panel. And controlling the scanning galvanometer to adjust the laser beam to the target position. According to the display panel, the light transmittance of the to-be-processed area can be improved, meanwhile, the possibility that a normal display area of the display panel is damaged is reduced, the use function of the to-be-processed area is guaranteed, and the display effect of the display panel is also guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of laser processing, in particular to a display panel processing device, method, display panel and controller. Background technique [0002] With the change of mobile phone and other terminal technologies, consumers are increasingly pursuing a higher screen-to-body ratio. However, due to the existence of essential front camera components and other sensors, it is necessary to reserve relevant areas on the display screen to Install related devices. In order to balance the higher screen-to-body ratio and front-facing shooting functions, it is necessary to place the camera components under the display screen so that external light can penetrate the screen and image on the sensor without affecting the display effect, that is, the under-screen The camera component solution requires high light transmittance in the area of ​​the camera component under the screen. However, the current display panel is compo...

Problems solved by technology

In order to balance the higher screen-to-body ratio and the front-facing camera function, it is necessary to place the camera components under the display screen so that the external light can penetrate the screen and image on the sensor without affecting the display effect, that is, the under-screen The camera component solution, which requires high light transmittance in the area of ​​the camera component under the screen, but the current display panel is composed of multi-layer materials, and there are also light-emitting pixel line units in the area of ​​the camera component under the screen. The complex multi-layer structure makes the overall The external light transmittance is low, and it is impossible to get a satisfactory front-facing shooting effect

[0003] Among them, one reason for the low transmittance of external light is that the cathode layer in the display panel structure will absorb and reflect external light. The material of this layer is usually magnesium-silver alloy, and the transmittance of visible light is below 50%, which seriously affects The use of camera components

In the related art, laser etching cathode is used to remove part of the cathode material. Part of the cathode material is the cathode material in the area where the camera component is located, but actually only needs to etch the corresponding cathode material inside the outline of the camera component. Therefore, redundant The etching affects the display effect of the display panel
