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.

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.

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 the embodiment of the present disclosure, 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 mutually independent components.

In one example, the functional device 20 may include at least one of: camera, earphone, light sensor, distance sensor, biosensor, environmental sensor, food safety detection sensor, health sensor, optical emitter. Wherein, the camera can be one or more in ordinary camera, infrared camera, degree of depth camera, structured light camera and the TOF camera for realize shooting the function. The earphone is used for realizing the 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 a portion of the functional device 20 requires light when operating, the light transmittance of the sub display region 12 is superior to that of the main display region 11. Optionally, the light transmittance of the sub-display area 12 is greater than 30% to meet the requirements of the camera and other devices for light transmittance. 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, since the functional device 20 has a requirement for light when operating, the operating state of the sub display region 12 may be adjusted according to the operating state of the functional device 20. For example, when the functional device 20 needs to collect an image, the sub display area 12 may be controlled to be in a closed state, so that light enters the functional device 20 through the sub display area, and the sub display area 12 does not display, so that interference to the light may be reduced, and the quality of the image collected by the functional device 20 may be ensured. When the functional device 20 does not need to collect an image, the sub-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 embodiment of the present disclosure, the display screen 10 is generally controlled by a driving chip, and the driving chip includes at least one of the following: 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.

In the process of implementing the embodiment of the present disclosure, the inventors found that: after the display screen is divided into the main display area and the auxiliary display area, the auxiliary display area needs to have higher light transmittance so as to meet the requirement of the functional device on light, and the POL is directly attached to the touch layer by using a setting process in the related art under the scene. Because the setting process is operated towards the whole screen, after the auxiliary display area is arranged in the display screen, the setting process in the related art has the attaching error and the process error, so that the POL enters the auxiliary display area, and the POL shields the light in the auxiliary display area to influence the camera to collect images.

Therefore, the display screen provided in the embodiment of the present disclosure has the inventive concept that marks are respectively arranged on the touch layer and the polarizer in the main display area 11, and the polarizer is attached to the touch layer after the marks of the two sides are aligned, so as to prevent the touch layer from entering the sub display area.

Referring to fig. 2, the main display area 11 of the display screen 10 at least includes a touch layer 121 and a polarizer 122. The touch layer 121 is provided with a first mark a, the polarizer 122 is provided with a second mark b, and the first mark a and the second mark b are aligned. Wherein, the alignment means that the centers of the first mark and the second mark coincide.

It should be noted that, in fig. 2, the touch layer 121 and the polarizer 121 have thicknesses, which are only schematic and do not reflect the actual thicknesses. The first mark a and the second mark b are "protruded" from the touch layer 121 and the polarizer 122, respectively, so as to highlight the first mark a and the second mark b, and do not define the first mark and the second mark. In some examples, the first mark a and the second mark b may be planar patterns, for example, obtained by laser etching or by ink writing. In other examples, the first mark a and the second mark b may be three-dimensional structures, and are obtained by a corresponding attaching process and a corresponding depositing process, which may also implement the solution of the present application.

In an embodiment of the present disclosure, the shape of the first mark a includes at least one of: cross, dot, circle, rectangle, diamond, and regular polygon. The shape of the second mark b includes at least one of: cross, dot, circle, rectangle, diamond, and regular polygon. The shape of the first mark a and the shape of the second mark b may be the same or different. The shape of the first mark a and the second mark b can be selected by the skilled person in a specific scenario, and the corresponding scheme falls within the scope of the present application.

To ensure the alignment accuracy, in the embodiment of the present disclosure, the number of the first marks a may be at least two, and the number of the second marks b may be at least two. The number of the first marks a and the number of the second marks b may be equal or unequal.

In an example, referring to fig. 3, if the number of the first marks a and the number of the second marks b are equal and are 3, the marks in the first marks a and the second marks b are aligned one by one.

In another example, referring to fig. 4, if the numbers of the first marks a and the second marks b are not equal, where the number of the first marks a is 3 and the number of the second marks b is 4, all the first marks a and some second marks b are aligned one by one, and the rest of the second marks b do not participate in the alignment. Of course, when the number of the first marks a is greater than the number of the second marks b, the number of all the second marks b is completely aligned, and the remaining marks in the first marks a no longer participate in the alignment. In other words, when the number of the first marks is not equal to that of the second marks, the marks having the smaller number of the first marks and the second marks are all aligned.

It can be understood that, in the embodiment of the disclosure, by aligning the first mark and the second mark, a process error of a set process in the related art can be removed, and the polarizer can be only located in the main display area, thereby preventing the polarizer from falling into the sub display area, improving the alignment accuracy of the polarizer and the touch layer, and ensuring the light transmittance of the sub display area.

Based on the display screens shown in the embodiments shown in fig. 1 to fig. 4, an embodiment of the present disclosure further provides a method for manufacturing a display screen, which includes, referring to fig. 5:

501, obtaining a first mark on a touch layer in a main display area in the display screen and obtaining a second mark on a polarizer.

In this embodiment, the first marks may be pre-disposed on the touch layer, and the shape and number of the first marks may refer to the content of the embodiments shown in fig. 2 to 4, which is not described herein again. Similarly, second marks may be further disposed on the touch layer in advance, and the shape and the number of the second marks may refer to the content of the embodiments shown in fig. 2 to fig. 4, which is not described herein again.

Before the lamination, the positions of the first mark on the touch layer and the second mark on the polarizer are obtained. Wherein:

the first mark may be acquired in a manner including:

in this embodiment, the fabrication of the corresponding layers, such as the TFT layer for display, on the substrate is completed by the set process in the related art until the touch layer is completed. On the basis, the camera is controlled to acquire an image containing the touch layer. Wherein, the camera can be one or more in ordinary camera, infrared camera, degree of depth camera, structured light camera and the TOF camera. The image may be a planar image or a structured light image.

Then, an image containing the touch layer is identified, so that a first mark on the touch layer can be obtained. For example, objects existing in the plane image may be recognized, and an object having the same shape as the first mark may be selected as the determined first mark. As another example, the first mark may be a three-dimensional structure, and an object having the same shape as the first mark may be recognized from the structured-light image as the determined first mark.

The obtaining manner of the second mark may refer to the obtaining manner of the first mark, and is not described herein again.

502, aligning the first mark and the second mark.

It should be noted that, when obtaining the images of the touch layer and the polarizer, the camera needs to perform a certain deflection, and the deflection may reflect the position relationship between the touch layer and the polarizer. Therefore, in the alignment process, the positions of the first mark and the second mark need to be changed to some extent, so as to align the marks on the touch layer and the polarizer.

503, attaching the polarizer to the touch layer.

And after alignment, the polaroid is attached to the touch layer. And then, executing other manufacturing processes to finish the manufacturing of the display screen.

Therefore, in the embodiment of the disclosure, by aligning the first mark and the second mark, the process error of the set process in the related art can be removed, and the polarizer can be only located in the main display area, so that the polarizer is prevented from falling into the auxiliary display area, thereby improving the alignment accuracy of the polarizer and the touch layer and ensuring the light transmittance of the auxiliary display area.
