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 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.

In order to ensure the display function of the auxiliary display area, more pixels need to be arranged in the auxiliary display area so as to ensure the display quality; in order to improve the light transmittance, the number of pixels needs to be reduced to reduce the light shielding. Thus, the display function in the sub display region and the light transmittance conflict with the requirements of the pixels.

In the process of implementing the embodiment of the present disclosure, the inventors found that: referring to fig. 2(a), when the display panel is an Organic Light-Emitting Diode (OLED) panel, each pixel in the sub-display area includes a plurality of driving lines, such as SCAN lines (SCAN lines), DATA lines (DATA lines), and power lines (VDD lines). When the display effect of the auxiliary display area is ensured, the number of the driving lines is increased in a geometric number mode, and therefore the light transmittance of the auxiliary display area is also influenced by the wiring in the auxiliary display area. Therefore, the disclosed embodiments provide a display screen, which is conceived to reduce the density of wires in a sub display area in the display screen and make the density of wires in the sub display area lower than that of wires in a high display area under the condition of ensuring the effective display area of the sub display area, so that the light transmittance of the sub display area can be better than that of the main display area.

In the embodiment of the present disclosure, the effect of reducing the wiring density in the sub-display area by adjusting the area of each pixel in the sub-display area 12 includes:

in one example, the width of the pixels in the sub display region 12 is adjusted such that the width of the pixels in the sub display region 12 is greater than the width of the pixels in the main display region 11. Fig. 2(a) is a schematic diagram illustrating pixel wiring in the main display area according to an exemplary embodiment, and fig. 2(b) is a schematic diagram illustrating pixel wiring in the sub display area according to an exemplary embodiment. Referring to fig. 2(a), the width a of each pixel in the sub display region in the present embodiment, referring to fig. 2(b), the width b of each pixel in the sub display region in the present embodiment, since the width b is greater than the width a, the number of pixels in the sub display region 12 can be reduced with the same width N. As is clear from a comparison between fig. 2(b) and fig. 2(a), when the number of pixels in the width direction is reduced, the data lines D1 to D8 corresponding to the pixels become the data lines D1 to D6, that is, the data lines within the width N are reduced, thereby reducing the density of the wirings in the sub-display area 12.

In another example, the height of the pixels in the sub display area 12 is adjusted such that the height of the pixels in the sub display area 12 is greater than the height of the pixels in the main display area 11. Fig. 3(a) is a schematic diagram illustrating pixel wiring in the main display area according to an exemplary embodiment, and fig. 3(b) is a schematic diagram illustrating pixel wiring in the sub display area according to an exemplary embodiment. Referring to fig. 3(a), the height c of each pixel in the sub display area in the present embodiment, referring to fig. 3(b), the height d of each pixel in the sub display area in the present embodiment, since the height d is greater than the height c, the number of pixels in the sub display area 12 can be reduced with the same height M. As is clear from a comparison between fig. 3(b) and fig. 3(a), when the number of pixels in the height direction is reduced, the scanning lines G1 to G8 corresponding to these pixels become the scanning lines G1 to G6, that is, the number of data lines in the height M is reduced, thereby reducing the density of the wirings in the sub-display area 12.

In yet another example, the width and height of the pixels in the sub display area 12 are adjusted such that the height of the pixels in the sub display area 12 is greater than the height of the pixels in the main display area 11 and the width of the pixels in the sub display area 12 is greater than the width of the pixels in the main display area 11. Fig. 4(a) is a schematic diagram illustrating pixel wiring in the main display area according to an exemplary embodiment, and fig. 4(b) is a schematic diagram illustrating pixel wiring in the sub display area according to an exemplary embodiment. Referring to fig. 4(a), the width a and the height c of each pixel in the sub display region in the present embodiment, referring to fig. 4(b), the width b and the height d of each pixel in the sub display region in the present embodiment, since the width b is greater than the width a and the height d is greater than the height c, the number of pixels in the sub display region 12 can be reduced in the same area MN. Comparing fig. 4(b) and fig. 4(a), it is understood that the scanning lines G1 to G8 corresponding to the pixels in the area MN are scanning lines G1 to G6, and the data lines D1 to D8 are data lines D1 to D6, thereby reducing the density of the wirings in the sub-display area 12.

The embodiment of the disclosure also provides a display screen, and fig. 5 is a schematic diagram of a display screen according to an exemplary embodiment. Referring to fig. 5, the display screen 10 includes a main display area 11, a transition display area 13, and a sub display area 12; and the density of the wiring in the transitional display area 13 is between the density of the wiring in the sub display area 12 and the main display area 11.

It should be noted that the display screen shown in fig. 5 has the same main display area 11 and sub-display area 12 as the display screen shown in fig. 1, and therefore, reference may be made to the contents of the embodiments shown in fig. 2(a) to fig. 2(b), fig. 3(a) to fig. 3(b), and fig. 4(a) to fig. 4(b) for the relevant contents of the main display area 11 and the sub-display area 12, which are not described herein again. The following embodiments describe only the differences between the display screen shown in fig. 5 and the display screen shown in fig. 1.

In practical applications, as the pixel area increases, the resolution of the sub-display area 12 decreases, so that the resolution jumps in the areas adjacent to the main display area 11 and the sub-display area 12, and the display effect is reduced. In order to ensure the display effect of the display screen, in an example, the area of the pixels in the transitional display area 13 is between the area of the pixels in the auxiliary display area 12 and the area of the pixels in the main display area 11, so that the resolution of the transitional display area 13 is between the main display area 11 and the auxiliary display area 12, the variation difference of the images in the main display area 11 and the auxiliary display area 12 is alleviated, and the display effect is favorably improved.

In another example, the number of the transition display regions 13 may be plural, such that the closer the transition display region 13 is to the sub display region 12, the larger the pixel area therein. Taking two transition display regions as an example, referring to fig. 6, the pixel area of the transition display region 131 is larger than the pixel area of the transition display region 132. Thus, the resolution of the transition display area 132 is between the main display area 11 and the transition display area 131, and the resolution of the transition display area 131 is between the transition display area 131 and the sub-display area 12, so that the image change in the plurality of stable transition areas is relatively slow, which is beneficial to improving the display effect.
