Detailed Description

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, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.

At present, partial electronic equipment's display screen can be divided into main display area and vice display area, can place the camera in the below of vice display area, and the camera can be through vice regional collection image of display area like this, needs vice display area to have the display function and have higher luminousness under this scene.

In practical application, a polarizer is further arranged in the display screen, wherein the polarizer is arranged in the main display area, and the polarizer is not arranged in the auxiliary display area. However, in the process of bonding the polarizer and the cover glass by using the optical cement, an open cavity is formed in the sub-display area, which is not favorable for defoaming the optical cement.

In order to solve the above problems, an embodiment of the present disclosure provides a display screen, and an inventive concept thereof is to arrange a filler at an opening region of a polarizer corresponding to a sub-display region, so that the filler and the polarizer form a closed region, thereby facilitating defoaming of a photo-adhesive in a subsequent process and ensuring effective discharge of bubbles in the sub-display region.

The disclosed embodiment provides a display screen, and fig. 1 is a schematic diagram of a display screen according to an exemplary embodiment. Referring to fig. 1, a display screen 10 includes a main display area 11 and a sub display area 12.

It should be noted that the display screen 10 includes two different types of display areas, namely, the main display area 11 and the sub display area 12, but the main display area 11 and the sub display area 12 are physically integrated, that is, the display screen 10 is an integrated structure, which is not divided into a plurality of independent components.

In the embodiment of the present disclosure, the main display area 11 and the sub display area 12 each have a display function. The number of the sub-display areas 12 may be one or plural. In fig. 1, the number of the sub display regions 12 is schematically illustrated as 1.

In an example, the camera 20 may be disposed below the sub-display area 12 for implementing a shooting function, and may be one or more of a general camera, an infrared camera, a depth camera, a structured light camera, and a TOF camera, so that the camera 20 occupying a display screen space may be disposed below the sub-display area 12, thereby maximally releasing a space of the display screen 10 and increasing a screen occupation ratio. If the display screen has a frame, only the frame brings certain reduction to the screen occupation ratio; if the display screen has no frame, the screen proportion can reach 100 percent, and the full screen in the true sense is realized.

In an example, the other device may include at least one of: an earpiece, a light sensor, a distance sensor, a biosensor, an environmental sensor, a food safety detection sensor, a health sensor, an optical emitter. The receiver is used for realizing a sound playing function. The light sensor is used for collecting the intensity of ambient light. The distance sensor is used for acquiring the distance of the front object. The biometric sensor is used for recognizing the biometric features of the user, such as a fingerprint recognition sensor, an iris recognition sensor, and the like. The environment sensor is used for collecting environment information, such as a temperature sensor, a humidity sensor, an air pressure sensor and the like. The food safety detection sensor is used for detecting indexes of harmful substances in food, such as an optical sensor, a biological recognition sensor and the like. The health sensor is used for collecting health information of a user, such as a sensor for collecting heart rate, blood pressure, heartbeat or other human body data of the user. An optical emitter is a functional device for emitting light, such as an infrared emitter or some emitter for emitting other light.

In the embodiment of the present disclosure, since the camera 20 requires light when operating, the light transmittance of the sub display area 12 is better 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. Optionally, the light transmittance of the sub-display area 12 is greater than 30% to meet the requirement of normal operation of the camera and other devices. In practical applications, a suitable material, a suitable process, or a suitable pixel distribution pattern may be selected according to the requirement of the device under the sub-display region for light transmittance, so as to produce the sub-display region 12 meeting the requirement of light transmittance.

In the embodiment of the present disclosure, in combination with the requirement of the camera 20 for light, the working state of the sub-display area 12 can be adjusted according to the working state of the camera 20. For example, when the camera 20 has the requirement of collecting images, the auxiliary display area 12 can be controlled to be in a closed state, so that light rays penetrate through the auxiliary display area to enter the camera 20, and the auxiliary display area 12 does not display, so that the interference to the light rays can be reduced, and the quality of collecting images by the camera 20 can be guaranteed. When the camera 20 does not need to collect images, the secondary display area 12 can be controlled to be in a display state, so that the display effect of the display screen is ensured.

In the disclosed embodiment, the display screen 10 is typically controlled by driver chips, at least one of which: the device comprises a line scanning driving chip, a data driving chip and a power supply chip. In one example, the main display area 11 and the sub display area 12 share the same driving chip, for example, one driving chip may be divided into two parts, one part for driving the main display area 11 and the other part for driving the sub display area 12. In another example, the main display area 11 and the sub display area 12 use different driving chips, for example, the display screen includes two driving chips, one driving chip is used for driving the main display area 11, and the other driving chip is used for driving the sub display area 12. In addition, when the display screen 10 includes a plurality of sub display regions 12, the plurality of sub display regions 12 may share the same driving chip, or different driving chips may be used, which is not limited in the present disclosure.

Fig. 2 is a front view of a display screen according to an exemplary embodiment, and referring to fig. 2, a display screen 10 includes a main display area 11 and a sub display area 12, wherein the sub display area 12 is located at an edge of the display screen. Moreover, the display panel 10 further includes a polarizer 13 and a filler 14, where the polarizer 13 is located in the main display area 11, that is, the polarizer 13 needs to form an opening area corresponding to the sub-display area 12, and the filler 14 is disposed in the opening area, so that the filler 14 and the polarizer 13 may enclose an enclosed area.

To this end, in the embodiment of the present disclosure, a polarizer is disposed in a main display area of a display screen, and the polarizer needs to form an opening area corresponding to a sub display area; the opening area is provided with the filler, makes filler and polaroid can enclose into a closed area, is favorable to setting up the defoaming of optical cement in-process, guarantees that the interior bubble of vice display area can effectively discharge, promotes the yield of display screen.
