Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of the present disclosure, as recited in the appended claims.

At present, the display screen of some electronic devices can be divided into a main display area and a secondary display area. A camera can be placed under the secondary display area, so that the camera can collect images through the secondary display area. In this scenario, the secondary display area needs to have a display function And has high transmittance.

In practical applications, a polarizer is also arranged in the display screen, wherein the polarizer is arranged in the main display area, and the polarizer is not arranged in the sub-display area. However, in the process of attaching the polarizer to the cover glass by using the optical glue, an open cavity will be formed in the sub-display area, which is not conducive to defoaming the optical glue.

In order to solve the above problems, an embodiment of the present disclosure provides a display screen, the inventive idea of which is to arrange a filler at the opening area of the polarizer corresponding to the secondary display area, so that the filler and the polarizer form a closed area, so as to form a closed area. It is convenient to deaerate the photosynthetic glue in the subsequent process, and ensure that the air bubbles in the secondary display area can be effectively discharged.

An embodiment of the present disclosure provides a display screen, and FIG. 1 is a schematic diagram of a display screen according to an exemplary embodiment. Referring to FIG. 1 , the display screen 10 includes a main display area 11 and a secondary display area 12 .

It should be noted that the display screen 10 includes two different types of display areas: the main display area 11 and the auxiliary display area 12, but the main display area 11 and the auxiliary display area 12 are a unified whole in terms of physical structure, that is, the display screen 10 is an integrated structure that is not divided into separate components.

In the embodiment of the present disclosure, both the main display area 11 and the sub-display area 12 have a display function. The number of the sub-display areas 12 may be one or more. In FIG. 1 , the number of sub-display areas 12 is taken as one for schematic illustration.

In an example, the camera 20 can be arranged below the sub-display area 12 to realize the shooting function, and can be one or more of a common camera, an infrared camera, a depth camera, a structured light camera and a TOF camera, which occupies The camera 20 in the display screen space can be arranged below the secondary display area 12 to maximize the release of the display screen 10 space and increase the screen ratio. If there is a frame on the display screen, only the frame will reduce the screen ratio to a certain extent; if there is no frame on the display screen, the screen ratio can reach 100%, achieving a full screen in the true sense.

In an example, the other devices may include at least one of the following: earpieces, light sensors, distance sensors, biosensors, environmental sensors, food safety detection sensors, health sensors, optical transmitters. Among them, the earpiece is used to realize the sound playback function. The light sensor is used to collect ambient light intensity. The distance sensor is used to collect the distance of the object ahead. Biosensors are used to identify the user's biometrics, such as fingerprint recognition sensors, iris recognition sensors, etc. Environmental sensors are used to collect environmental information, such as temperature sensors, humidity sensors, and air pressure sensors. Food safety detection sensors are used to detect indicators of some harmful substances in food, such as optical sensors, biometric sensors, etc. The health sensor is used to collect the user's health information, such as a sensor used to collect the user's heart rate, blood pressure, heartbeat or other human body data. Optical emitters are functional devices that emit light, such as infrared emitters or some emitters that emit other light.

In the embodiment of the present disclosure, since the camera 20 needs light when working, the light transmittance of the sub display area 12 is higher than that of the main display area 11. For example, the light transmittance of the sub display area 12 is greater than that of the main display area. 11 transmittance. Optionally, the light transmittance of the secondary display area 12 is greater than 30%, so as to meet the normal working requirements of the camera and other devices on the light transmittance.
