Detailed ways

In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below with reference to the accompanying drawings. All other embodiments obtained under the premise of creative work fall within the scope of protection of the present application.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" can be the same or a different subset of all possible embodiments, and Can be combined with each other without conflict.

In the following description, the term "first\second\third" is only used to distinguish similar objects, and does not represent a specific ordering of objects. It is understood that "first\second\third" Where permitted, the specific order or sequence may be interchanged to enable the embodiments of the application described herein to be practiced in sequences other than those illustrated or described herein.

Unless otherwise defined, all technical and scientific terms used in the embodiments of the present application have the same meaning as commonly understood by those skilled in the technical field of the present application. The terms used in the embodiments of the present application are only for the purpose of describing the embodiments of the present application, and are not intended to limit the present application.

Before the embodiments of the present application are described in further detail, the nouns and terms involved in the embodiments of the present application are described. The nouns and terms involved in the embodiments of the present application are suitable for the following explanations:

1) Pixel array: a plurality of light-emitting units arranged on the pixel layer in a certain way, each light-emitting unit is a pixel, and the pixel layer is usually a thin film layer composed of organic material molecules. The pixels on the pixel layer emit light. Generally, an organic light-emitting semiconductor (Organic Light-Emitting Diode, OLED) screen has a pixel layer composed of organic material molecules.

2) Micro-lens: It belongs to passive optical element and is used to converge and diverge light radiation in optical system.

In the related art, in order to achieve certain effects, a conventional OLED screen needs to be divided into a main screen area and a sub-screen area, and a camera is correspondingly arranged in the sub-screen area. The sub-screen area is a special screen with low reflectivity and high light transmittance. The sub-screen area has dual functions and can be used as a normal display area during display. When the camera is taking pictures, the sub-screen area will become. Transparent to allow light to pass through, allowing the camera to take pictures. The current off-screen camera technology is mainly to improve the screen structure, lens imaging and camera algorithm to achieve full-screen display of mobile phones and user-acceptable off-screen camera effects. One of the current mainstream solutions is to improve the OLED display panel and electronic devices of mobile phones, so that the pixel density of the under-screen camera display area is smaller than that of the normal display area. By reducing the pixel density of the under-screen camera display area, the under-screen camera is improved. The transmittance of the display area can realize the dual functions of under-screen camera and full-screen display.

Because the display pixels in the screen are opaque, the light received by the camera under the screen is insufficient. More importantly, the arrangement of opaque pixels in the screen is similar to a micro-nano-level grid structure, which changes the broad pass function of the camera and affects the transmittance function of the camera's optical system, and, Diffraction effects will be generated, which will affect the optical modulation transfer function (MTF) of the camera, and eventually lead to a serious degradation of the imaging quality of the camera. Although, theoretically, by changing the pixel density of the sub-screen area and the ratio of the light-transmitting area, the optical modulation transfer function of the camera can be improved, thereby improving the imaging quality, but it has caused the display effect of the sub-screen area and the entire screen to decline. This solution cannot take into account the photographing effect of the camera and the display effect of the screen. In addition, in theory, the method of image processing and algorithm optimization can improve the shooting effect of the under-screen camera to a certain extent, but the hardware structure of the sub-screen area corresponding to the camera has completely limited the imaging quality, even if image processing is used. And algorithm, also can not get real, clear image.

Based on this, the embodiments of the present application provide a display panel, an image display device and method, a terminal, and a storage medium, in which a guide with good light conductivity can be arranged between each adjacent pixel point in the pixel point corresponding to the light-transmitting display area.

The imaging quality of the image acquisition device disposed at the position corresponding to the light-transmitting display area in the display device.
