AI Technical Summary

Technical Problem

In the prior art, the curved display portion of the display panel has low display brightness at a normal viewing angle and cannot match the flat display portion.

Method used

A cover plate is designed, including a light-adjusting surface and a connecting surface. The distance between the light-adjusting surface and the connecting surface gradually decreases. The light-adjusting surface is used to alleviate the oblique emission of light from the curved display part. Through refractive index adjustment and structural design, the emitted light is made perpendicular to the flat display part, thereby improving the display brightness of the curved display part.

Benefits of technology

At the normal viewing angle, the display brightness of the curved display part is significantly improved and the distribution is more even, which improves the user's viewing experience.

Abstract

The present application provides a cover plate and a display module, wherein the cover plate is used for a display panel, wherein the display panel includes a curved display portion and a flat display portion, wherein the curved display portion is curved toward the cover plate, and the cover plate is located on the light-emitting side of the display panel; the cover plate includes a first surface and a second surface relative to each other along a first direction, wherein the first surface is close to the display panel, and the first surface includes a light-adjusting surface corresponding to the curved display portion; along the second direction, the distance between the light-adjusting surface and the second surface gradually decreases, wherein the first direction is perpendicular to the second direction. The light-adjusting surface can be used to alleviate the degree of inclination of the light emitted obliquely from the curved display portion after passing through the cover plate. Therefore, the cover plate and display module provided by the present application can improve the display brightness of the display module at the curved display portion at a normal viewing angle.
