[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0054] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] As described in the background technology section, in actual applications, the display differences between different display areas of some display devices are large, resulting in users being able to observe display mutations when viewing the displayed images, especially for low grayscale display panels. The display mutation phenomenon is more serious and the viewing experience needs to be improved.

[0056] The inventors have found that this is because when current display devices integrate other functions besides display in the display area, they usually occupy a certain area of ​​the display area of ​​the display panel in the display device. In order to achieve the same pixel points in different display areas, the wiring and pixel circuit setting space for driving the light-emitting elements in the display panel can only be sacrificed, resulting in a large difference in the number of light-emitting elements driven by a pixel circuit used to drive the light-emitting elements in different display areas, which in turn leads to large display differences between different display areas, causing users to observe sudden display changes when watching the display screen, and the viewing experience needs to be improved.

[0057] In view of this, an embodiment of the present application provides a display panel, such as Figure 1As shown, the display panel includes a first display area 10, a second display area 20 and a transition display area 30 located between the first display area 10 and the second display area 20, wherein the first display area includes a plurality of first sub-display areas, the second display area includes a plurality of second sub-display areas, and the transition display area includes at least one sub-transition area.

[0058] like Figure 2 As shown, Figure 2 for Figure 1 In the partial enlarged view of the dotted line frame area, the first sub-display area 11, the second sub-display area 21 and the sub-transition display area 31 include the same number of light-emitting elements 40, wherein the number of pixel circuits for driving each light-emitting element 40 of the sub-transition area 31 is greater than the number of pixel circuits for driving each light-emitting element 40 of the first sub-display area 11, and is less than the number of pixel circuits for driving each light-emitting element 40 of the second sub-display area 21, so that the number of pixel circuits for driving each light-emitting element 40 of the sub-transition area 31 is located at the same level as the number of pixel circuits for driving each light-emitting element 40 of the first sub-display area 11. 0 and the number of pixel circuits for driving each light-emitting element 40 of the second sub-display area 21, so that when the display panel displays a picture, the display effect of the sub-transition area 31 is between the display effect of the first sub-display area 11 and the display effect of the second sub-display area 21, that is, the display effect of the transition display area is between the display effect of the first display area and the display effect of the second display area, and the display effect of the transition display area is used to achieve a transition between the display effect of the first display area and the display effect of the second display area, thereby reducing the display difference viewed by the user when viewing the display picture and improving the user experience.

[0059] The number of pixel circuits used to drive each light-emitting element in the sub-transition zone is a first number, the number of pixel circuits used to drive each light-emitting element in the first sub-display zone is a second number, and the number of pixel circuits used to drive each light-emitting element in the second sub-display zone is a third number, then the first number is greater than the second number and less than the third number.

[0060] It should be noted that although Figure 1 middle, Figure 1 The dotted line frame area shown extends from the lower area of ​​the first display area to the second display area, but the present application is not limited to this. In other embodiments of the present application, Figure 1The dotted frame area shown can also extend from the upper area of ​​the first display area to the second display area, or extend from the left area of ​​the first display area to the second display area, or extend from the right area of ​​the first display area to the second display area. The present application does not limit this, as long as the dotted frame area includes part of the first display area, part of the transition display area and part of the second display area.

[0061] Based on the sensitivity of the human eye, the transition display area includes a plurality of sub-transition areas, each of which includes at least one row of sub-pixel rows and at least one column of sub-pixel columns, so as to reduce the display difference when the user views the display image and improve the user experience. Specifically, in this embodiment, among the plurality of sub-transition areas, the number of pixel circuits used to drive each light-emitting element in at least part of the sub-transition areas is greater than the number of pixel circuits used to drive each light-emitting element in one of the first sub-display areas, and is less than the number of pixel circuits used to drive each light-emitting element in one of the second sub-display areas.

[0062] like Figure 3 As shown, in the multiple sub-transition zones, the number of pixel circuits used to drive each light-emitting element in each sub-transition zone is greater than the number of pixel circuits used to drive each light-emitting element in one of the first sub-display zones, and is less than the number of pixel circuits used to drive each light-emitting element in one of the second sub-display zones.

[0063] In the plurality of sub-transition regions, the number of pixel circuits for driving each light-emitting element in each sub-transition region is the same, and the Figure 3 As shown, in the multiple sub-transition regions, the number of pixel circuits for driving each light-emitting element in each sub-transition region is a first number, which is greater than the second number and less than the third number.

[0064] like Figure 4 As shown, in the plurality of sub-transition regions, the number of pixel circuits for driving each light-emitting element in each sub-transition region is not completely the same. Figure 4 As shown, in the multiple sub-transition regions, the number of pixel circuits used to drive the respective light-emitting elements of some of the sub-transition regions is a first number, and the number of pixel circuits used to drive the respective light-emitting elements of some of the sub-transition regions is a fourth number, the first number is greater than the second number and less than the third number, the fourth number is greater than the second number and less than the third number, but the first number and the fourth number are different.

[0065] It should be noted that the above embodiments are described by taking the example that, in the multiple sub-transition zones, the number of pixel circuits for driving the light-emitting elements in each sub-transition zone is greater than the number of pixel circuits for driving the light-emitting elements in the first sub-display zone, and is less than the number of pixel circuits for driving the light-emitting elements in the second sub-display zone, but the present application is not limited to this. In other embodiments of the present application, in the multiple sub-transition zones, the number of pixel circuits for driving the light-emitting elements in a part of the sub-transition zones may be greater than the number of pixel circuits for driving the light-emitting elements in the first sub-display zone, and is less than the number of pixel circuits for driving the light-emitting elements in the second sub-display zone; the number of pixel circuits for driving the light-emitting elements in another part of the sub-transition zones is equal to the number of pixel circuits for driving the light-emitting elements in the first sub-display zone, or is equal to the number of pixel circuits for driving the light-emitting elements in the second sub-display zone, depending on the specific circumstances.

[0066] The light emitting element in the display panel may be an OLED or an LED, which is not limited in the present application and depends on the specific situation. The following describes the display panel provided in the embodiment of the present application by taking the light emitting element being an OLED as an example.

[0067] like Figure 5 As shown, the display panel includes: a first substrate 1, a plurality of pixel circuits located on a first side of the first substrate 1, and a plurality of light-emitting elements 40 located on a side of the pixel circuit away from the first substrate 1, wherein the pixel circuit includes a thin film transistor 2, and the thin film transistor 2 is used to control the working state of the light-emitting element 40. Specifically, the light-emitting element 40 includes a cathode, an anode, and a light-emitting layer located between the cathode and the anode, wherein the anode is electrically connected to the drain of the thin film transistor to cooperate with the cathode to control the light-emitting state of the light-emitting layer under the voltage applied by the thin film transistor. The display panel can be a top-emitting display panel, and the light-emitting element 40 emits light toward a side away from the first substrate 1, that is, Figure 5 The upper side of the display panel in the embodiment is the display side 101 , and the lower side is the non-display side 102 .

[0068] Continue as Figure 5 As shown, the display panel also includes: a planarization layer 3 covering the thin film transistor 2, and a pixel definition layer 4 located on the side of the planarization layer 3 away from the first substrate 1, the pixel definition layer 4 has a plurality of openings, and the light-emitting layer corresponds to the openings one by one and is located in the openings.

[0069] The multiple light-emitting elements may include OLEDs of multiple colors, so that different colors of light are emitted by OLEDs of different colors to display a color picture, such as the OLEDs of multiple colors include red OLED, blue OLED and green OLED, etc.; it should be noted that, in this embodiment, one OLED corresponds to one sub-pixel.

[0070] In another embodiment of the present application, the display panel includes a light-emitting element layer and a color conversion layer, wherein the light-emitting element layer includes a plurality of OLEDs emitting light of the same color, and the color conversion layer includes a quantum dot layer, so as to form different emission colors under the excitation of light emitted by the OLEDs emitting light of the same color, thereby realizing the display of a color picture. Among them, the OLED emitting light of the same color can be a blue OLED or a green OLED, which is not limited in the present application and depends on the specific circumstances. It should be noted that in the present embodiment, an OLED and its corresponding color conversion layer portion are combined into a light-emitting element, corresponding to a sub-pixel.

[0071] When the display panel includes light-emitting elements of multiple colors, the light-emitting elements driven by one pixel circuit may all be light-emitting elements of the same color.

[0072] It should be noted that, with the development of light sensing technology, more and more display devices are integrated with optical sensors to realize light collection, thereby integrating more functions in the display devices, such as image collection function, fingerprint recognition function, etc. Correspondingly, a light-transmitting area needs to be set in the display panel to provide light for the display device integrated with the optical sensor.

[0073] The first display area includes a light-transmitting area. Figure 1 As shown, the second display area is arranged around the first display area; in another embodiment of the present application, as shown Figure 6 As shown, the second display area surrounds three sides of the first display area. In other embodiments of the present application, the first display area and the second display area can also be arranged side by side or in other relative positions. The present application does not limit this and it depends on the specific circumstances.

[0074] like Figure 7 As shown, the display panel includes a plurality of sub-pixels 50, each of which includes an opening area 51 and a non-opening area 52, wherein the light-emitting element is located in the opening area 51 of the sub-pixel 50, and the light-transmitting area is located in the non-opening area 52 between adjacent sub-pixels 50. Specifically, the light-transmitting area is composed of light-transmitting holes 60 located in the non-opening area between adjacent sub-pixels 50. In another embodiment, as Figure 8As shown, the display panel includes a plurality of pixel units 70, each pixel unit 70 includes an opening area 71 and a non-opening area 72, wherein a pixel unit 70 may include a red light-emitting element, a green light-emitting element and a blue light-emitting element, each light-emitting element is located in the opening area 71 of the pixel unit 70, and the light-transmitting area is located in the non-opening area 72 between adjacent pixel units, so as to increase the size of a single light-transmitting hole 60, but the present application does not limit this, and it depends on the specific circumstances.

[0075] The transitional display area 30 does not include a light-transmitting area.

[0076] The light-emitting elements in the display panel include light-emitting elements of three colors: a first light-emitting element, a second light-emitting element, and a third light-emitting element. In the first sub-display area, one pixel circuit is electrically connected to at least two light-emitting elements, specifically, in the first sub-display area, one pixel circuit is electrically connected to at least two light-emitting elements of the same color, so as to leave more space for setting the light-transmitting area; in the second sub-display area, one pixel circuit is electrically connected to one light-emitting element, so that each light-emitting element in the second sub-display area can be displayed independently, thereby improving the display resolution of the display panel; in the sub-transition area, each pixel circuit in some pixel circuits is electrically connected to at least two light-emitting elements, and each pixel circuit in the remaining pixel circuits is electrically connected to one light-emitting element, specifically, in the sub-transition area, each pixel circuit in some pixel circuits is electrically connected to at least two light-emitting elements of the same color, and each pixel circuit in some pixel circuits is electrically connected to one light-emitting element of the same color, so that each light-emitting element in one sub-transition area is driven by a plurality of light-emitting elements. The number of pixel circuits of the element is greater than the number of pixel circuits used to drive each light-emitting element of the first sub-display area, and is less than the number of pixel circuits used to drive each light-emitting element of the second sub-display area, so that the number of pixel circuits used to drive each light-emitting element of the sub-transition area is between the number of pixel circuits used to drive each light-emitting element of the first sub-display area and the number of pixel circuits used to drive each light-emitting element of the second sub-display area, so that when the display panel displays a picture, the display effect of the sub-transition area is between the display effect of the first sub-display area and the display effect of the second sub-display area, that is, the display effect of the transition display area is between the display effect of the first display area and the display effect of the second display area, and the display effect of the transition display area is used to achieve a transition between the display effect of the first display area and the display effect of the second display area, thereby reducing the display difference viewed by the user when viewing the displayed picture and improving the user experience.

[0077] Specifically, the pixel circuit may be a 7T1C circuit, that is, a pixel circuit includes 7 thin film transistors and 1 capacitor. Fig. 9and Figure 5 As shown, Fig. 9 FIG. 4 shows a schematic diagram of a circuit structure in which a pixel circuit P drives a light-emitting element 40, that is, a schematic diagram of a circuit structure in which a pixel circuit P is electrically connected to a light-emitting element 40. Figure 5 FIG. 4 shows a partial cross-sectional view of a pixel circuit P driving a light emitting element 40; Fig.10 and Fig.11 As shown, Fig.10 FIG. 1 shows a schematic diagram of a circuit structure in which a pixel circuit P drives two light-emitting elements 40, that is, a schematic diagram of a circuit structure in which a pixel circuit P is electrically connected to two light-emitting elements 40. Fig.11 A partial cross-sectional view showing one pixel circuit P driving two light emitting elements 40 is shown.

[0078] The light-emitting elements in the display panel include light-emitting elements of three colors: a first light-emitting element, a second light-emitting element and a third light-emitting element. The sub-transition zone includes at least one transition light-emitting element and at least one non-transition light-emitting element. The transition light-emitting element selects one or two of the first light-emitting element, the second light-emitting element and the third light-emitting element, and the rest are non-transition light-emitting elements.

[0079] The transition light-emitting elements are arranged as follows: the number of transition light-emitting elements in the sub-transition zone driven by one pixel circuit is equal to the number of transition light-emitting elements in the first sub-display zone driven by one pixel circuit and is greater than the number of transition light-emitting elements in the second sub-display zone driven by one pixel circuit, that is, in the sub-transition zone, in the pixel circuit driving the transition light-emitting elements, one pixel circuit is electrically connected to at least two light-emitting elements. Optionally, in this embodiment, the electrical connection method between the transition light-emitting elements located in the sub-transition zone and their corresponding pixel circuits is the same as the electrical connection method between the transition light-emitting elements located in the first sub-display zone and their corresponding pixel circuits.

[0080] The non-transition light-emitting elements are arranged as follows: the number of non-transition light-emitting elements in the sub-transition zone driven by one pixel circuit is less than the number of non-transition light-emitting elements in the first sub-display zone driven by one pixel circuit and is equal to the number of non-transition light-emitting elements in the second sub-display zone driven by one pixel circuit, that is, in the sub-transition zone, in the pixel circuit driving the non-transition light-emitting elements, one pixel circuit is electrically connected to one light-emitting element. Optionally, in this embodiment, the electrical connection method between the non-transition light-emitting elements located in the sub-transition zone and their corresponding pixel circuits is the same as the electrical connection method between the non-transition light-emitting elements located in the second sub-display zone and their corresponding pixel circuits.

[0081] The number of light-emitting elements included in the first sub-display area, the second sub-display area and the sub-transition area are eight, namely, two blue light-emitting elements, two red light-emitting elements and four green light-emitting elements. In the first sub-display area, for the pixel circuit driving the red light-emitting element, each pixel circuit drives two red light-emitting elements, for the pixel circuit driving the blue light-emitting element, each pixel circuit drives two blue light-emitting elements, and for the pixel circuit driving the green light-emitting element, each pixel circuit drives two green light-emitting elements, so as to take into account the display resolution and light transmittance of the display panel, but the present application is not limited to this. In other embodiments of the present application, in the first sub-display area, a pixel circuit can also drive other numbers of light-emitting elements of the same color, depending on the specific circumstances.

[0082] Specifically, continue as Figure 2 As shown, the number of light-emitting elements included in the first sub-display area, the second sub-display area and the sub-transition area are all eight, which are two blue light-emitting elements, two red light-emitting elements and four green light-emitting elements.

It should be noted that in Figure 2 In FIG. 1 , the light-emitting elements connected by the same connection line are light-emitting elements driven by the same pixel circuit. Figure 2 In the subsequent electrical connection diagrams, only the light-emitting elements and connecting lines are shown, and the pixel circuit is no longer shown.

[0083] The display panel provided in the embodiment of the present application is described below in combination with specific embodiments, taking as an example that in the first sub-display area, a pixel circuit drives two light-emitting elements of the same color, and in the second sub-display area, a pixel circuit drives one light-emitting element of the same color.

[0084] Specifically, in one embodiment of the present application, the first light-emitting element is a blue light-emitting element, the second light-emitting element is a red light-emitting element, and the third light-emitting element is a green light-emitting element.

[0085] Optionally, in one embodiment of the present application, the transition light-emitting element selects one of the first light-emitting element, the second light-emitting element and the third light-emitting element, and the rest are non-transition light-emitting elements.

[0086] In one embodiment of the present application, the transition light emitting element is a first light emitting element, and the non-transition light emitting element is a second light emitting element and a third light emitting element. That is, in this embodiment, Fig.12 As shown, the blue light emitting element 41 is a transition light emitting element, and the red light emitting element 42 and the green light emitting element 43 are non-transition light emitting elements.

[0087] Continue as Fig.12 As shown, in the first sub-display area 11, the pixel circuit electrically connected to the blue light-emitting element 41 is one pixel circuit electrically connected to two blue light-emitting elements 41, the pixel circuit electrically connected to the red light-emitting element 42 is one pixel circuit electrically connected to two red light-emitting elements 42, and the pixel circuit electrically connected to the green light-emitting element is one pixel circuit electrically connected to two green light-emitting elements 43.

[0088] In the sub-transition region 31, a pixel circuit electrically connected to the blue light-emitting element 41 is electrically connected to two blue light-emitting elements 41, a pixel circuit electrically connected to the red light-emitting element 42 is electrically connected to one red light-emitting element 42, and a pixel circuit electrically connected to the green light-emitting element 43 is electrically connected to one green light-emitting element 43;

[0089] In the second sub-display area 21, the pixel circuit electrically connected to the blue light-emitting element 41 is one pixel circuit electrically connected to the blue light-emitting element 41, the pixel circuit electrically connected to the red light-emitting element 42 is one pixel circuit electrically connected to the red light-emitting element 42, and the pixel circuit electrically connected to the green light-emitting element 43 is one pixel circuit electrically connected to the green light-emitting element 43.

[0090] The light-emitting elements in the first sub-display area in the first display area adopt a "one drives many" method. When the arrangement density of the light-emitting elements is the same or similar, the number of pixel circuits is reduced and the transmittance is improved. The second sub-display area in the second display area adopts a "one drives one" method, so that the resolution of the second display area is higher. However, due to the large difference in the driving relationship between the pixel circuits and the light-emitting elements in the first display area and the second display area, the difference in display effects between the first display area and the second display area is more obvious, thereby forming a boundary between the first display area and the second display area.

[0091] The human eye has different sensitivities to different colors. The human eye is more sensitive to green than to red, and less sensitive to blue than to red. By setting the blue light-emitting element as a transitional light-emitting element, on the one hand, it plays a transitional role between the first display area and the second display area in terms of display resolution. At the same time, it reduces the sensitivity of the human eye to the different display effects between the first display area and the transitional display area, and reduces the sensitivity to the different display effects between the transitional display area and the second display area, thereby weakening the difference in display effects between the first display area and the second display area.
