Display components and terminals

technical field

The invention relates to the field of display screens, in particular to a display screen component and a terminal.

Background technique

The display assembly of a traditional mobile phone is composed of a cover plate and a display screen. The cover plate is stacked on the display screen. The inner surface of the cover plate is generally divided into two parts: the ink area and the display area. The ink area is on the inner surface of the cover plate. It is formed by coating an ink layer. The ink layer is used to cover the area where the image cannot be displayed on the edge of the display screen, and the display area is the area where the cover plate can effectively display the image of the display screen. Usually, the ink area is on the appearance surface of the cover plate. No image can be displayed, so that the ratio of the display area to the outer surface of the cover plate cannot be increased, and a larger display screen cannot be obtained, so it is not ergonomic.
