[0001] The present disclosure relates to the field of display technology, and in particular to a display screen and an electronic device. Background Art

[0002] At present, the display screens of some electronic devices can be divided into a main display area and a secondary display area.

In this scenario, the secondary display area is required to have a display function and a high light transmittance.

[0003] In order to ensure the transmittance of the secondary display area, corresponding improvements need to be made to the cathode and / or anode of the pixels in the secondary display area. In this way, after the display screen is turned off, the reflectivity of the main display area and the secondary display area is different, resulting in an obvious "jumping" feeling in the display effects of the main display area and the secondary display area, affecting the viewing experience.

[0030] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0031] At present, the display screens of some electronic devices can be divided into a main display area and a secondary display area. A camera can be placed below the secondary display area so that the camera can capture images through the secondary display area. In this scenario, the secondary display area is required to have a display function and a high light transmittance.

[0032] In order to ensure the transmittance of the secondary display area, corresponding improvements need to be made to the cathode and / or anode of the pixels in the secondary display area. In this way, after the display screen is turned off, the reflectivity of the main display area and the secondary display area is different, resulting in an obvious "jumping" feeling in the display effects of the main display area and the secondary display area, affecting the viewing experience.

[0033] To solve the above problems, an embodiment of the present disclosure provides a display screen. The inventive concept is to set a transition display area between the main display area and the auxiliary display area, and then the polarizer can be located in part of the main display area and the transition display area. In this way, the reflectivity of the main display area and the auxiliary display area can be buffered by the transition display area to achieve the effect of increasing the reflectivity successively, thereby avoiding the display "jumping" phenomenon in the main display area and the auxiliary display area, and improving the display effect and viewing experience.

[0034] The embodiment of the present disclosure provides a display screen, Figure 1FIG is a schematic diagram of a display screen according to an exemplary embodiment. Figure 1 The display screen 10 includes a main display area 11 and a sub-display area 12.

[0035] 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 physical structure, that is, the display screen 10 is an integrated structure and is not divided into multiple independent components.

[0036] In the embodiment of the present disclosure, both the main display area 11 and the auxiliary display area 12 have display functions. The number of auxiliary display areas 12 can be one or more. Figure 1 In the figure, the number of the auxiliary display area 12 is 1 for schematic illustration.

[0037] In one example, the camera 20 can be located below the secondary display area 12 for capturing images. It can be one or more of a standard camera, an infrared camera, a depth camera, a structured light camera, and a time-of-flight (TOF) camera. This allows the camera 20, which otherwise occupies display space, to be located below the secondary display area 12, maximizing the space available on the display 10 and increasing the screen-to-body ratio. If the display has a bezel, only the bezel will reduce the screen-to-body ratio to a certain extent. If the display has no bezel, the screen-to-body ratio can reach 100%, achieving a truly full-screen display.

[0038] In one example, other devices may include at least one of the following: an earpiece, a light sensor, a distance sensor, a biometric sensor, an environmental sensor, a food safety detection sensor, a health sensor, and an optical emitter. The earpiece is used to implement a sound playback function. The light sensor is used to collect ambient light intensity. The distance sensor is used to collect the distance of an object in front. The biometric sensor is used to identify the user's biometric characteristics, such as a fingerprint recognition sensor, an iris recognition sensor, etc. The environmental sensor is used to collect environmental information, such as a temperature sensor, a humidity sensor, and an air pressure sensor. The food safety detection sensor is used to detect indicators of certain harmful substances in food, such as an optical sensor, a biometric sensor, etc. The health sensor is used to collect the user's health information, such as a sensor for collecting the user's heart rate, blood pressure, heartbeat, or other human body data. The optical emitter is a functional device for emitting light, such as an infrared emitter or some emitters for emitting other light.

[0039] In the disclosed embodiment, since the camera 20 requires light when operating, the transmittance of the secondary display area 12 is superior to that of the primary display area 11. For example, the transmittance of the secondary display area 12 is greater than that of the primary display area 11. Optionally, the transmittance of the secondary display area 12 is greater than 30% to meet the normal transmittance requirements of the camera and other devices. In actual applications, appropriate materials, processes, or pixel distribution can be selected based on the transmittance requirements of the devices below the secondary display area to produce a secondary display area 12 that meets the above transmittance requirements.

[0040] In the disclosed embodiment, the operating state of the secondary display area 12 can be adjusted based on the camera 20's light requirements. For example, when the camera 20 needs to capture images, the secondary display area 12 can be controlled to be in an off state, allowing light to pass through the secondary display area and enter the camera 20. Since the secondary display area 12 is not displaying, interference with light is reduced, which helps to ensure the quality of images captured by the camera 20. When the camera 20 does not need to capture images, the secondary display area 12 can be controlled to be in a display state to ensure the display quality of the display screen.

[0041] In an embodiment of the present disclosure, the display screen 10 is generally controlled by a driver chip, at least one of which is a row scan driver chip, a data driver chip, and a power chip. In one example, the main display area 11 and the auxiliary display area 12 share the same driver chip. For example, a driver chip can be divided into two parts, one part is used to drive the main display area 11, and the other part is used to drive the auxiliary display area 12. In another example, the main display area 11 and the auxiliary display area 12 use different driver chips. For example, the display screen includes two driver chips, one of which is used to drive the main display area 11, and the other is used to drive the auxiliary display area 12. In addition, when the display screen 10 includes multiple auxiliary display areas 12, the multiple auxiliary display areas 12 can share the same driver chip or use different driver chips, and the present disclosure is not limited to this.

[0042] To ensure the display function of the secondary display area, more pixels are required to ensure display quality; to improve light transmittance, fewer pixels are needed to reduce light obstruction. This creates a conflict between the display function and light transmittance requirements of the secondary display area.

[0043] In one embodiment of the present disclosure, while ensuring the effective display area of the secondary display area, the density of wiring in the secondary display area of the display screen is reduced, so that the density of wiring in the secondary display area is lower than the density of wiring in the main display area, thereby making the transmittance of the secondary display area better than the transmittance of the main display area.

[0044] In the embodiment of the present disclosure, the area of each pixel in the secondary display area 12 is adjusted to reduce the wiring density in the secondary display area, including:

[0045] In one example, the width of the pixels in the secondary display area 12 is adjusted so that the width of the pixels in the secondary display area 12 is greater than the width of the pixels in the main display area 11. Figure 2(a) is a schematic diagram of pixel wiring in the main display area according to an exemplary embodiment, and Figure 2(b) is a schematic diagram of pixel wiring in the secondary display area according to an exemplary embodiment. Referring to Figure 2(a), the width a of each pixel in the main display area in this embodiment, and referring to Figure 2(b), the width b of each pixel in the secondary display area in this embodiment, since the width b is greater than the width a, the number of pixels in the secondary display area 12 can be reduced under the same width N. Comparing Figure 2(b) and Figure 2(a), it can be seen that when the number of pixels in the width direction is reduced, the data lines D1 to D8 corresponding to these pixels become data lines D1 to D6, that is, the number of data lines within the width N is reduced, thereby reducing the density of wiring in the secondary display area 12.

[0046] In another example, the height of the pixels in the secondary display area 12 is adjusted so that the height of the pixels in the secondary display area 12 is greater than the height of the pixels in the main display area 11. Figure 3(a) is a schematic diagram of pixel wiring in the main display area according to an exemplary embodiment, and Figure 3(b) is a schematic diagram of pixel wiring in the secondary display area according to an exemplary embodiment. Referring to Figure 3(a), the height c of each pixel in the main display area in this embodiment, and referring to Figure 3(b), the height d of each pixel in the secondary display area in this embodiment, since the height d is greater than the height c, the number of pixels in the secondary display area 12 can be reduced under the same height M. Comparing Figure 3(b) and Figure 3(a), it can be seen that when the number of pixels in the height direction is reduced, the scan lines G1 to G8 corresponding to these pixels become scan lines G1 to G6, that is, the data lines within the height M are reduced, thereby reducing the density of wiring in the secondary display area 12.

[0047] In another example, the width and height of the pixels in the secondary display area 12 are adjusted so that the height of the pixels in the secondary 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 secondary display area 12 is greater than the width of the pixels in the main display area 11. Figure 4(a) is a schematic diagram of pixel wiring in the main display area according to an exemplary embodiment, and Figure 4(b) is a schematic diagram of pixel wiring in the secondary display area according to an exemplary embodiment. Referring to Figure 4(a), the width a and height c of each pixel in the main display area in this embodiment are shown, and referring to Figure 4(b), the width b and height d of each pixel in the secondary display area in this embodiment are shown. 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 secondary display area 12 can be reduced under the same area MN. Comparing Figure 4(b) with Figure 4(a), it can be seen that the scan lines G1 to G8 corresponding to the pixels in area MN are changed to scan lines G1 to G6, and the data lines D1 to D8 are changed to data lines D1 to D6, thereby reducing the density of wiring in the secondary display area 12.

[0048] In order to improve the light transmittance of the secondary display area, in the embodiment of the present disclosure, the anode of the pixel in the secondary display area 12 is made of indium oxide ITO. If other transparent materials with good conductivity can be obtained, the anode can also be replaced by other materials. The anode of the pixel in the main display area 12 is made of indium tin oxide and silver, and the structure can be ITO / Ag / ITO. In one example, the anode of the pixel in the transition display area 13 and the anode of the pixel in the secondary display area 12 are made of the same material, such as indium oxide ITO. In this embodiment, the anodes of the pixels in the secondary display area 12 and the transition display area 13 are made of the same material, so that the secondary display area 12 and the transition display area 13 can have the same reflectivity, which is convenient for subsequent adjustments.

[0049] The embodiment of the present disclosure also provides a display screen, Figure 5 FIG is a schematic diagram of a display screen according to an exemplary embodiment. Figure 5 The display screen 10 includes a main display area 11, a transition display area 13 and a sub-display area 12; and the wiring density in the transition display area 13 is between the wiring density in the sub-display area 12 and the main display area 11.

[0050] It should be noted that Figure 5 The display shown is the same as Figure 1 The display screen shown has the same main display area 11 and auxiliary display area 12, so the relevant contents of the main display area 11 and auxiliary display area 12 can be found in Figure 2(a) to Figure 2(b) 、 Figure 3(a) to Figure 3(b) and Figure 4(a) to Figure 4(b) The contents of the embodiment shown are not described here in detail. Figure 5 The display shown and Figure 1 Differences between the displays shown.

[0051] In actual applications, as the pixel area increases, the resolution of the secondary display area 12 decreases, resulting in a resolution jump in the area adjacent to the primary display area 11 and the secondary display area 12, reducing the display quality. To ensure the display quality of the display screen, in one example, the area of the pixels in the transitional display area 13 is between the area of the pixels in the secondary display area 12 and the area of the pixels in the primary display area 11. In this way, the resolution of the transitional display area 13 is between that of the primary display area 11 and the secondary display area 12, mitigating the difference in image changes between the primary display area 11 and the secondary display area 12, thereby improving the display quality.

[0052] In another example, the number of transition display areas 13 can be multiple, so that the closer the transition display area 13 is to the auxiliary display area 12, the larger the pixel area therein. Figure 6 The pixel area of the transition display area 131 is larger than that of the transition display area 132. In this way, 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 auxiliary display area 12. In this way, the image changes in multiple smooth transition areas are relatively slow, which is conducive to improving the display effect.

[0053] Figure 7 is a front view of a display screen according to an exemplary embodiment, see Figure 7 A display screen 10 includes a main display area 11, a transitional display area 13, and a secondary display area 12. The transitional display area 13 is located between the main display area 11 and the secondary display area 12. The display screen 10 also includes a polarizer 14, which is disposed within the display screen 10 and is therefore indicated by a dotted line. The polarizer 14 is disposed within the main display area 11 and within a portion 131 of the transitional display area 13 adjacent to the main display area 11.

[0054] Since the reflectivity of the area covered by the polarizer 14 in the display screen is low, while the reflectivity of the uncovered area is high, the reflectivity of the partial area 131 in the transition display area 13 where the polarizer 14 is provided will be lower than the reflectivity of the partial area 132 where the polarizer 14 is not provided, that is, the reflectivities of the main display area 11, the partial area 131 in the transition display area 13 where the polarizer 14 is provided, the partial area 132 in the transition display area 13 where the polarizer 14 is not provided, and the sub-display area 12 increase successively. In this way, the reflectivity from the main display area 11 to the sub-display area 12 changes slowly, which can ensure that the display effect of the display screen 10 tends to be consistent after the screen is turned off, thereby improving the display effect and user experience.

[0055] In order to ensure that the polarizer 14 is located within the transition display area 13, the width of the transition display area 13 is adjusted in one embodiment of the present disclosure. Taking into account that the polarizer has a cutting error E1 and an application error E2, when the cutting error E1 and the application error E2 are both negative, the polarizer reaches a negative maximum value, that is, a negative value of the error; when the cutting error E1 and the application error E2 are both positive, the polarizer reaches a positive maximum value, that is, a positive value of the error. In this way, the maximum error change of the cutting error E1 and the application error E2 is the difference between the positive and negative values of the error of the polarizer 14, that is, (+E1+E2)-(-E1-E2). Based on the above, in this embodiment, the width of the transition display area 13 needs to be greater than the maximum error change of the polarizer. For example, if the maximum error change of the polarizer is 0.3mm=+0.15-(-0.15)mm, the width of the transition display area 13 needs to be greater than 0.30mm, such as 0.35~0.50mm. In this embodiment, by adjusting the width of the transition display area 13 , the polarizer 14 can be located in the transition display area 13 regardless of the error, thereby preventing the polarizer 14 from entering the auxiliary display area 12 or remaining in the main display area 11 .
