Problems solved by technology
However, if the hole-digging part of the polarizer is not filled, but directly stacked with other layers of the display screen, it is easy to cause other layers to cause problems such as depressions and breakage at the hole-digging part
In the existing technology, during the molding process of the display screen, glue is dispensed on the hole-digging part of the polarizer to fill the hole-digging part. This method is difficult to control the amount of glue dispensing, and the dispensing material often overflows, causing the appearance Defective, or there is insufficient dispensing amount to generate air bubbles, which will cause the display screen to be easily deformed in this part and affect the optical imaging

The present application discloses a display screen, which includes a display panel, an optically transparent resin layer, a polarizer, an optically transparent adhesive layer, and a cover plate that are stacked in sequence, wherein the polarizer includes a polarizer body and a polarizer Transparent glue layer. The polarizer body is provided with a through hole, the polarizer transparent adhesive layer is stacked on the polarizer body, and the surface of the polarizer transparent adhesive layer facing the polarizer body is extended with a raised portion , the raised portion is filled in the through hole. The application also provides a polarizer and an electronic device. The present application designs a polarizer including a polarizer body and a polarizer transparent adhesive layer. Since the through hole passing through the polarizer body can be completely filled in advance by the polarizer transparent adhesive layer, the polarizer forms a through hole for light to pass through. At the same time, it avoids the bad problem caused when the polarizer is attached to other layers of the display screen.
Description
technical field [0001] The present invention relates to the field of display, in particular to a polarizer structure, a display screen with the polarizer structure, and an electronic device. Background technique [0002] At present, in order to increase the screen ratio, the under-screen camera solution came into being. By placing the camera under the display screen, there is no need to open a hole in the display screen to expose the camera, which can effectively increase the size of the display screen. However, in order to allow the camera to obtain external light through the display screen, one of the existing methods is to remove the part of the structure corresponding to the camera part in the display screen, for example, the part of the polarizer corresponding to the camera part is cut through holes etc. removed, so that light can enter the inside of the display screen from the outside and be received by the camera. However, if the holed portion of the polarizer is not...
