Problems solved by technology

As a result, the design of optical components such as cameras and optical sensors on the side of the display panel has become a problem. Setting them on the edge of the display panel will reduce the screen ratio and affect the appearance; setting them under the screen will affect the lighting and poor reliability of light collection. The imaging quality of the camera is low, and the detection accuracy of the optical sensor is poor

Embodiment Construction

[0028] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0029] At present, terminals using AMOLED display panels are becoming more and more popular. At the same time, for video calls and other needs, terminal equipment will also be equipped with a camera on the front of the display panel, or a corresponding optical sensor for detection needs. Cameras, optical sensors or other optical components often need to collect external optics through ...

Abstract

The invention relates to a display panel, a display screen and a terminal. The display panel is provided with a light-transmitting display area corresponding to an optical assembly arranged below the display panel, and comprises a first electrode, a second electrode, a third electrode and a fourth electrode, the luminescent material layer is arranged below the first electrode; the second electrode is arranged below the light-emitting material, and the polarity of the second electrode is opposite to that of the first electrode; at least in the light-transmitting display area, a gap for light to pass through is formed in the second electrode; and the second electrode comprises a reflective layer and an anti-reflection layer arranged on one side, close to the optical assembly, of the reflective layer, and the anti-reflection layer is used for absorbing light reflected by the optical assembly. According to the display panel, the anti-reflection layer is arranged on the side, close to the optical assembly, of the reflection layer, so that reflected light generated when incident light passes through the optical assembly below the screen is prevented from entering the optical assembly again through reflection of the reflection layer, the daylighting influence of the display panel on the optical assembly is reduced, and the reliability of light collection is improved.

Description

technical field [0001] The present disclosure relates to the field of display technologies, and in particular, to a display panel, a display screen and a terminal. Background technique [0002] Currently, terminals such as mobile phones and tablet computers use AMOLED (Active-matrix organic light-emitting diode) display panels. Moreover, in a full-screen terminal device, in order to increase the screen-to-body ratio, the area of ​​the display panel is continuously enlarged. As a result, the design of optical components such as cameras and optical sensors on the side of the display panel has become a problem. Setting them on the edge of the display panel will reduce the screen ratio and affect the appearance; setting them under the screen will affect the lighting and poor reliability of light collection. The imaging quality of the camera is low, and the detection accuracy of the optical sensor is poor. Contents of the invention [0003] In order to overcome the problems e...
