Abstract

The invention provides a cover plate, a display panel and a method for making the cover plate. The cover plate includes a glass cover plate, the glass cover plate includes a hole-digging area; an encapsulation layer, the encapsulation layer is arranged on one side of the glass cover plate; a buffer layer , the buffer layer is arranged on the side of the glass cover plate away from the encapsulation layer, the buffer layer is arranged on the hole-digging area on the glass cover plate, and the buffer layer is used to buffer the stress generated by the encapsulation layer when the hole is dug in the hole-digging area. In this solution, a buffer layer is arranged on the hole-digging area of ​​the glass cover plate, which reduces the stress on the packaging layer when the hole is dug in the hole-digging area, and improves the yield rate of the cover plate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a cover plate, a display screen and a method for manufacturing the cover plate. Background technique [0002] With the development of display panel technology, display devices with a high screen-to-body ratio are becoming more and more popular. [0003] Existing display devices generally adopt hole-digging technology to achieve a high screen-to-body ratio. Because the existing display devices are generally packaged with glass glue, and glass glue is a ceramic material with high brittleness. Therefore, when digging a hole in the mobile phone screen, the stress generated will cause cracks in the glass glue, which will cause cell phone yield. reduce. Contents of the invention [0004] The object of the present invention is to provide a cover plate, a display screen and a manufacturing method of the cover plate, which improves the yield rate of the cover plate. [0005] An embo...
