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.

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 space of the display screen 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 earphone 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 may be selected according to the requirement of the device under the sub-display area on light transmittance, so as to produce the sub-display area 12 meeting the requirement on 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 acquire an image, the auxiliary display area 12 can be controlled to be in a display state, so that the display effect of the display screen is ensured.

In order to increase the light transmittance of the sub-display area, a driving line may be used to drive the same-color sub-pixels in the sub-display area, and referring to fig. 2, the scanning lines of all the red sub-pixels in the sub-display area 12 are a line G1, the data lines of all the red sub-pixels are a line D2, and the driving lines of all the red sub-pixels are a line (not shown in the figure), so that the wiring density of the sub-display area may be reduced, and the transmittance of the sub-display area may be increased. It should be noted that, for convenience of drawing and description, the first row of the sub-display area of fig. 2 only shows red sub-pixels, the second row only shows green sub-pixels, and the third row only shows blue sub-pixels.

If a driving line is used to drive the same-color sub-pixels, the same-color sub-pixels in the sub-display area can be simultaneously bright or dark, so that the sub-display area can only display a color block, the display capability is low, and the display effect is reduced.

For this reason, in the embodiment of the present disclosure, on the basis of the display screen shown in fig. 1, the secondary display area in the display screen includes at least two sub-areas; the same-color sub-pixels in each sub-area share the same drive line. In this way, in this embodiment, by dividing the sub display area into at least two sub areas, each sub area can display different contents, so that the display capability of the sub display area can be improved, and the display effect of the display screen can be improved.

In embodiments of the present disclosure, the drive line includes at least one of: scan lines, data lines, and power lines. Of course, if the same-color sub-pixels in the sub-display region also share the pixel compensation circuit, the driving lines may further include connection lines between the pixel compensation circuit and each sub-pixel, and technicians may adjust the type and number of the driving lines according to specific scenes, and the corresponding scheme falls within the scope of the present application.

In one example, at least two sub-areas within the secondary display area may have different arrangements, including at least one of: the auxiliary display area is transversely arranged, the auxiliary display area is longitudinally arranged and the auxiliary display area is obliquely arranged. The skilled person can select a suitable arrangement according to a specific scenario, which is not limited herein.

In an example, at least two sub-areas are arranged laterally in the sub-display area, see fig. 3, and the sub-display area 12 includes a sub-area 121 and a sub-area 122. Referring to fig. 4, taking the sub-region 121 as an example, the scan lines of all the red sub-pixels in the sub-region 121 share one scan line G1, the data lines of all the red sub-pixels in the sub-region 121 share one data line D1, and the power lines of all the red sub-pixels in the sub-region 121 share one power line (not shown in the figure). Continuing with fig. 4, taking the sub-region 122 as an example, the scan lines of all the red sub-pixels in the sub-region 122 share one scan line G1', the data lines of all the red sub-pixels in the sub-region 122 share one data line D1', and the power lines of all the red sub-pixels in the sub-region 121 share one power line (not shown in the figure).

With reference to fig. 3 and fig. 4, in this embodiment, the sub-display area 12 is divided into two sub-areas, so that the sub-area 121 and the sub-area 122 can be used as two different color blocks to respectively display different contents, thereby improving the display capability of the sub-display area and improving the display effect of the display screen.

It can be understood that the display effect of the sub display area 12 is better as the number of sub areas increases, but the light transmittance of the sub display area is affected by the increase of the number of sub areas. Therefore, the number of sub-areas in the sub-display area can be adjusted by technicians according to the display effect and the light transmittance, and the corresponding scheme falls into the protection scope of the application.

In another example, at least two sub-areas are arranged longitudinally in the sub-display area as an example, and referring to fig. 5, the sub-display area 12 includes a sub-area 123 and a sub-area 124. Referring to fig. 6, taking the sub-region 123 as an example, the scan lines of all the red sub-pixels in the sub-region 123 share one scan line G1, the data lines of all the red sub-pixels in the sub-region 123 share one data line D1, and the power lines of all the red sub-pixels in the sub-region 123 share one power line (not shown in the figure). Continuing to refer to fig. 6, taking the sub-region 124 as an example, the scan lines of all the red sub-pixels in the sub-region 124 share one scan line G1', the data lines of all the red sub-pixels in the sub-region 124 share one data line D1', and the power lines of all the red sub-pixels in the sub-region 124 share one power line (not shown).

With reference to fig. 5 and fig. 6, in this embodiment, the sub-display area 12 is divided into two sub-areas, so that the sub-area 123 and the sub-area 124 can be used as two different color blocks to respectively display different contents, thereby improving the display capability of the sub-display area and improving the display effect of the display screen.

In yet another example, at least two sub-areas are arranged longitudinally within the secondary display area for example, see fig. 7, the secondary display area 12 includes a sub-area 125 and a sub-area 126. Referring to fig. 8, taking the sub-region 125 as an example, the scan lines of all the red sub-pixels in the sub-region 123 share one scan line (not shown), the data lines of all the red sub-pixels in the sub-region 123 share one data line D1, and the power lines of all the red sub-pixels in the sub-region 123 share one power line (not shown). Continuing to refer to fig. 8, taking the sub-region 126 as an example, the scan lines of all the red sub-pixels in the sub-region 126 share one scan line (not shown in the figure), the data lines of all the red sub-pixels in the sub-region 126 share one data line D1', and the power lines of all the red sub-pixels in the sub-region 126 share one power line (not shown in the figure).

With reference to fig. 7 and fig. 8, in this embodiment, the sub-display area 12 is divided into two sub-areas, so that the sub-area 125 and the sub-area 126 can be used as two different color blocks to respectively display different contents, thereby improving the display capability of the sub-display area and improving the display effect of the display screen.

In one embodiment of the present disclosure, the display screen 10 is generally controlled by a driving circuit, which may include at least one of: a scan circuit, a data circuit, and a power supply circuit. Of course, the driving circuit may further include a pixel compensation circuit, and a technician may adjust the type and number of the driving lines according to a specific scenario, and the corresponding scheme falls within the scope of the present application.

Considering that the sub-display region 12 includes at least two sub-regions, in one example, at least two sub-regions may share the same driving circuit, for example, one driving circuit may be divided into at least two parts, and each part drives a corresponding sub-region. In another example, at least two sub-regions may use different driving circuits, e.g., the sub-display region includes at least two driving circuits, each driving a corresponding sub-region, respectively.

Considering that the display screen includes the main display area 11 and the sub display area 12, in one example, at least one sub-area in the main display area 11 and the sub display area 12 shares the same driving circuit, for example, one driving circuit may be divided into two parts, one part is used for driving the main display area 11, and the other part is used for driving at least one sub-area in the sub display area 12. In another example, the main display area 11 and the sub display area 12 use different driving circuits, for example, the display panel includes at least two driving circuits, one driving circuit for driving the main display area 11 and the remaining at least one driving circuit for driving the sub display area 12.
