Description

Technical Field

[0001] This application belongs to the field of display technology, and in particular relates to a display panel and display device. Background Technology

[0002] With the development of automotive intelligence, in-vehicle display systems are no longer limited to a single navigation function. They often need to meet users' higher display requirements. For example, in scenarios where the driver and passenger need to obtain different information at the same time (such as the driver looking at navigation and the passenger watching a movie), the in-vehicle display screen needs to show a dual-view image.

[0003] Existing technologies for the above display scenarios often physically divide the display screen into two independent display areas. Although the above solutions can achieve dual-view display, the number of pixels displayed on each side is greatly reduced, resulting in a poor user viewing experience. Summary of the Invention

[0004] This application provides a display panel and display device that can improve the display quality of dual-viewing angle displays on vehicle-mounted screens.

[0005] In a first aspect, embodiments of this application provide a display panel, including: substrate; The device layer is located on one side of the substrate. The device layer includes multiple sub-pixel columns, which are arranged along a first direction. Each sub-pixel column includes multiple sub-pixels arranged along a second direction. The sub-pixels in the same sub-pixel column include first-type sub-pixels and second-type sub-pixels. The light emission angles of the first-type sub-pixels and the second-type sub-pixels are different. The first direction and the second direction intersect.

[0006] Secondly, embodiments of this application provide a display device, comprising: The display panel as described in any of the first aspects above.

[0007] The display panel and display device provided in this application, by dividing the same column of sub-pixels in the vehicle display screen into first-class sub-pixels and second-class sub-pixels with different viewing angles, enable the display panel to provide users with independent images without interference from each other from different viewing angles. Furthermore, by setting a sub-pixel column to include both first-class and second-class sub-pixels, the concentrated distribution of one type of sub-pixel can be reduced, thereby reducing the sense of display fragmentation and improving the display effect.

[0016] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0017] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0018] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies: In the automotive display field, especially for automotive organic light-emitting diode (OLED) displays, users are increasingly demanding dual-viewing-angle displays. Currently, dual-viewing-angle display solutions for automotive displays often include the following: The first is to physically divide the display screen into two different areas, but this solution significantly reduces the number of pixels displayed on each side, severely impacting the user's viewing experience.

[0019] The second method is to adopt, as shown in... Figure 1 The display panel shown has a pixel arrangement, such as Figure 1 The display includes R subpixels that emit red light, G subpixels that emit green light, and B subpixels that emit blue light. Odd-numbered subpixels (subpixels numbered 1) can display the view from the left, while even-numbered subpixels (subpixels numbered 2) can display the view from the right. However, this display scheme produces visible vertical stripes during actual display, creating a sense of disjointedness and resulting in a poor user experience.

[0020] Based on this, embodiments of this application provide a display panel and a display device that can solve the above-mentioned problems. The following is a detailed description of a display panel provided by an embodiment of this application.

[0021] In some embodiments, such as Figure 2 As shown, this application embodiment provides a display panel 100, which may include: Substrate 10; Device layer, located on one side of the substrate, the device layer includes multiple sub-pixel columns, the multiple sub-pixel columns are arranged along a first direction (horizontal direction), the sub-pixel columns include multiple sub-pixels arranged along a second direction (vertical direction), the sub-pixels in the same sub-pixel column include a first type of sub-pixel 101 and a second type of sub-pixel 102, wherein the light emission angle of the first type of sub-pixel 101 is different from that of the second type of sub-pixel 102, and the first direction and the second direction intersect.

[0022] Here, as Figure 1 As shown, in a column of sub-pixels, the first type of sub-pixels 101 and the second type of sub-pixels 102 can be arranged alternately. The light emission angles of the two types of sub-pixels are different. For example, the light emission angle of the first type of sub-pixels 101 can be biased to the left, and the light emission angle of the second type of sub-pixels 102 can be biased to the right.

[0023] In some examples, the light emission angle of different sub-pixels can be changed by altering the direction of the active layer channel of the driving transistor in the pixel circuit of the sub-pixel. The active layer channel of the driving transistor of the first type of sub-pixel 101 can extend along the second direction to make its light emission angle biased to the left; the active layer channel of the driving transistor of the first type of sub-pixel 101 can extend along the first direction to make its light emission angle biased to the right.

[0024] In some examples, light-blocking structures can be set in the different sub-pixels mentioned above to change the light emission angle of the different sub-pixels, which will not be elaborated here.

[0025] In some examples, both the first type of sub-pixels 101 and the second type of sub-pixels 102 can include RGB sub-pixels of different emission colors. For example, the first type of sub-pixels 101 includes sub-pixels of R1, G1, and B1; the second type of sub-pixels 102 can include sub-pixels of R2, G2, and B2. In the first column of sub-pixels, they can be arranged in the order of R1-R2-G1-G2-B1-B2; in the second column of sub-pixels, they can be arranged in the order of G1-G2-B1-B2-R1-R2; in the third column of sub-pixels, they can be arranged in the order of R1-R2-G1-G2-B1-B2; the fourth column of sub-pixels has the same arrangement order as the first column of sub-pixels, and so on. The above arrangement makes the first type of sub-pixels 101 and the second type of sub-pixels 102 alternately mixed in both the row and column directions, which can avoid the display graininess caused by the concentrated arrangement of sub-pixels with the same emission angle.

[0026] Based on the above-mentioned display panel, this application embodiment can realize that a column of sub-pixels can simultaneously include a first type of sub-pixels and a second type of sub-pixels with different light emission angles in a display scenario in a vehicle. Under the premise of realizing dual-view display, it can avoid defects such as display stripes caused by the concentrated distribution of sub-pixels with the same view angle, and improve the display effect.

[0027] In some embodiments, such as Figure 2 middle, Figure 2 This is a schematic diagram of an exemplary display panel. The display panel also includes a plurality of data lines extending along a second direction. The data lines include a first data line 201 and a second data line 202. A first type of sub-pixel 101 is electrically connected to the first data line 201, and a second type of sub-pixel 102 is electrically connected to the second data line 202.

[0028] Here, in the second direction, for any column of subpixels, the first data line 201 can be set to be located on one side of the subpixel column, and the second data line 202 can be located on the other side of the subpixel column. As shown in the figure, for any subpixel column, the first data line 201 is located on the left side of the subpixel column, and the second data line 202 is located on the right side of the subpixel column.

[0029] like Figure 2 As shown, in a subpixel column, first-type subpixels 101 and second-type subpixels 102 are alternately arranged along a second direction. Exemplarily, the first-type subpixels 101 are connected to the first data line 201 via a first switching unit, and the second-type subpixels 102 are connected to the second data line 202 via a second switching unit. The control terminal of the first switching unit is connected to the first scan line, and the control terminal of the second switching unit is connected to the second scan line.

[0030] In some examples, such as Figure 2 As shown, in a subpixel row, first-type subpixels 101 and second-type subpixels 102 are arranged alternately along a second direction. This minimizes the clustering of similar subpixels, avoiding defects such as stripes in dual-view displays, thereby improving the display effect.

[0031] During the data writing phase of a display frame, the first and second scan lines synchronously output scan signals, controlling the simultaneous activation of the first switching unit corresponding to the first type of sub-pixel 101 and the second switching unit corresponding to the second type of sub-pixel 102 located in the same sub-pixel row. This allows the data voltage transmitted by the first data line 201 and the second data line 202 to be written in parallel to the first type of sub-pixel 101 and the second type of sub-pixel 102 in that row. Therefore, the display panel can achieve line-by-line writing of grayscale voltage, which helps to eliminate vertical stripes and graininess, improving the uniformity of the displayed image.

[0032] Alternatively, the control terminals of the first switching unit corresponding to all first-type sub-pixels 101 and the second switching unit corresponding to all second-type sub-pixels 102 in the same sub-pixel row are connected to the same scan line, so that when the scan line outputs a scan signal, synchronous grayscale voltage writing of all sub-pixels in the row can be achieved.

[0033] It is conceivable that the above-mentioned display panel can realize both dual-view display and privacy display. Specifically, in the dual-view display mode, during the data writing stage of a display frame, the driver chip can simultaneously output the grayscale voltage for normal display to the first data line 201 and the second data line 202, so that both the first type of sub-pixel 101 and the second type of sub-pixel 102 emit light normally.

[0034] In the privacy display mode, during the data writing stage of a display frame, the driver chip can simultaneously output a grayscale voltage for normal display to the first data line 201 and a black state voltage to the second data line 202, so that the first type of sub-pixel 101 emits light normally, while the second type of sub-pixel 102 displays a black state.

[0035] This application embodiment sets a first type of sub-pixel in a sub-pixel column to be connected to a first data line, and a second type of sub-pixel to be connected to a second data line. This enables the driver chip to transmit different data signals to the first type of sub-pixel and the second type of sub-pixel simultaneously, thereby achieving differentiated driving of the two types of sub-pixels and thus realizing dual-view display.

[0036] In some embodiments, in the same sub-pixel column, the first type of sub-pixels 101 and the second type of sub-pixels 102 are arranged alternately.

[0037] like Figure 2 As shown, in a column of subpixels, the first type of subpixels 101 and the second type of subpixels 102 can be arranged alternately, that is, in a column of subpixels, the arrangement is alternating between the first type of subpixels 101-the second type of subpixels 102-the first type of subpixels 101-the second type of subpixels 102, or the arrangement is alternating between the second type of subpixels 102-the first type of subpixels 101-the second type of subpixels 102-the first type of subpixels 101.

[0038] Based on this, by setting the first type of sub-pixels and the second type of sub-pixels alternately in a sub-pixel column, the display panel can achieve the simultaneous emission of light from two different viewing angles by the two types of sub-pixels in the automotive display scenario, displaying images from two different viewing angles, while displaying uniformly without graininess, thus improving the user's viewing experience.

[0039] In some embodiments, such as Figure 2 As shown, in the same row of sub-pixels, the first type of sub-pixels 101 and the second type of sub-pixels 102 are arranged alternately. That is, in a row of sub-pixels, any two adjacent sub-pixels are either the first type of sub-pixel 101 and the second type of sub-pixel 102, or the second type of sub-pixel 102 and the first type of sub-pixel 101. Based on the above pixel arrangement, the first type of sub-pixels and the second type of sub-pixels can be arranged as evenly as possible, improving display uniformity.

[0040] In some embodiments, such as Figure 3 As shown, Figure 3 As another exemplary display panel schematic diagram, the subpixel column includes multiple subpixel groups arranged along a second direction, the multiple subpixels in the same subpixel group have the same emission color, one subpixel in the same subpixel group is a first type subpixel 101, the other subpixel is a second type subpixel 102, and the first type subpixel 101 and the second type subpixel 102 in the same subpixel group are arranged adjacent to each other in the second direction.

[0041] like Figure 3In this context, a subpixel column may include multiple subpixel groups. A subpixel group may include a first type of subpixel 101 and a second type of subpixel 102 that emit the same color. For example, a subpixel group may include a first subpixel group that emits red light, a second subpixel group that emits blue light, and a third subpixel group that emits green light. The first subpixel group includes R1R2, where R1 is the first type of subpixel 101 and R2 is the second type of subpixel 102. Similarly, the second subpixel group includes B1B2, and the third subpixel group includes G1G2.

[0042] like Figure 3 In a subpixel column, the first subpixel group, the second subpixel group, and the third subpixel can be arranged alternately. At the same time, in a subpixel row, the first subpixel group, the second subpixel group, and the third subpixel group can also be arranged alternately.

[0043] Please continue to refer to this. Figure 3 Based on the above subpixel arrangement structure, in actual display, subpixels can be reused across columns to form different pixel units. For example, the first type of subpixel R1 in the first row and first column, the first type of subpixel B1 in the first row and second column, and the first type of subpixel G1 in the first row and third column can form a pixel unit (Pixel 1) to jointly achieve the illumination of a display pixel. Meanwhile, the first type of subpixel G1 in the first row and third column, the first type of subpixel R1 in the first row and fourth column, and the first type of subpixel B1 in the first row and fifth column can form another pixel unit (Pixel 2).

[0044] Please refer to Figure 4 , Figure 4 This is a schematic diagram of another type of display panel. It's conceivable that, in the case of multiple subpixels within a subpixel column, the first type of subpixels 101 and the second type of subpixels 102 can also be arranged alternately within a subpixel row. And as in... Figure 4 In the pixel arrangement shown, subpixels can also be reused across columns. For example, subpixels of type 1 in the first row and first column R1, subpixels of type 1 in the second row and second column B1, and subpixels of type 1 in the first row and third column G1 can form a pixel unit (Pixel 3). At the same time, subpixels of type 1 in type 1 in type 1 in type 3 column G1, subpixels of type 1 in type 1 in type 4 column R1, and subpixels of type 1 in type 1 in type 5 column B1 can form another pixel unit (Pixel 4).

[0045] In the two pixel units mentioned above, G1 is shared and reused by both pixel units. Thus, without increasing the total number of sub-pixels, pixel rendering at different spatial locations can be achieved by changing the combination of sub-pixels, thereby improving the display effect.

[0046] The embodiments of this application are based on the above-mentioned column of sub-pixels including multiple sub-pixel groups, and a sub-pixel group including a first type of sub-pixel and a second type of sub-pixel with the same emission color. This is beneficial to realize the sharing and reuse of sub-pixels in different pixel units, and improve the density of pixel units without increasing the number of sub-pixels.

[0047] In some embodiments, such as Figure 5 As shown, Figure 5 This is a schematic diagram of another type of display panel. The subpixel columns include a first subpixel column and a second subpixel column. The first subpixel column includes a first subpixel group and a second subpixel group. The second subpixel column includes a third subpixel group. The emission colors of the first subpixel group, the second subpixel group, and the third subpixel group are different from each other.

[0048] like Figure 5 In this context, the sub-pixel group may include a first sub-pixel group that emits red light, a second sub-pixel group that emits blue light, and a third sub-pixel group that emits green light. The first sub-pixel group includes R1R2, the second sub-pixel group includes B1B2, and the third sub-pixel group includes G1G2.

[0049] Odd-numbered subpixel columns may include alternating first and second subpixel groups, while even-numbered subpixel columns may include a third subpixel group; alternatively, even-numbered subpixel columns may include alternating first and second subpixel groups, while odd-numbered subpixel columns may include a third subpixel group. It is conceivable that the aforementioned first and second subpixel columns can be alternating. For example, the first subpixel group includes R1R2, where R1 is a first-type subpixel 101 and R2 is a second-type subpixel 102. Similarly, the second subpixel group includes B1B2, and the third subpixel group includes G1G2.

[0050] Based on this, the embodiments of this application, by including a first sub-pixel group and a second sub-pixel group in the first sub-pixel column and a third sub-pixel group in the second sub-pixel column, can relatively increase the number of third sub-pixel groups. Since the emission color of the third sub-pixel group (e.g., green sub-pixels) is the main source of brightness perceived by the human eye, this design enables the display panel to match the visual characteristics of the human eye, thereby significantly improving the brightness and display quality of the display panel.

[0051] In some embodiments, in the second direction, the first sub-pixel group and the second sub-pixel group in the same sub-pixel column are arranged alternately; and in the first direction, the first sub-pixel group and the second sub-pixel group in the same sub-pixel row are arranged alternately.

[0052] For example, such as Figure 5In the image, the first column of subpixels includes R1-R2-B1-B2-R1-R2 and so on, and the second column of subpixels includes G2-G1-G2-G1 and so on. Based on this, subpixels can be reused across columns to form different pixel units. For example, the first type of subpixel R1 in the first row and first column, the first type of subpixel G1 in the second row and second column, and the first type of subpixel B1 in the first row and third column can form a pixel unit (Pixel 5) to collectively achieve the illumination of a display pixel. Simultaneously, the first type of subpixel B1 in the first row and third column, the first type of subpixel G1 in the second row and fourth column, and the first type of subpixel R1 in the first row and fifth column can form another pixel unit (Pixel 6).

[0053] In some examples, when odd-numbered subpixel columns include the first and second subpixel groups, and even-numbered subpixel columns include the third subpixel group, the pixel arrangement can be maintained such that odd-numbered subpixel rows include the first type of subpixels and even-numbered subpixel rows include the second type of subpixels. This will not be elaborated further here.

[0054] This application embodiment sets the first sub-pixel group and the second sub-pixel in a sub-pixel column to be arranged alternately, and the first sub-pixel and the second sub-pixel in a sub-pixel row to be arranged alternately. This can reduce the gap between sub-pixels from different viewing angles and further reduce the sense of disjointedness caused by display stripes. This can achieve dual-view display in vehicle scenarios and improve the display effect.

[0055] In some embodiments, such as Figure 5 Specifically, in the first sub-pixel column, the first type of sub-pixel 101 is located in odd-numbered rows, and the second type of sub-pixel 102 is located in even-numbered rows; in the second sub-pixel column, the first type of sub-pixel 101 is located in even-numbered rows, and the second type of sub-pixel 102 is located in odd-numbered rows.

[0056] It is conceivable that in the first sub-pixel column, the first type of sub-pixel 101 is located in even-numbered rows, and the second type of sub-pixel 102 is located in odd-numbered rows; in the second sub-pixel column, the first type of sub-pixel 101 is located in odd-numbered rows, and the second type of sub-pixel 102 is located in even-numbered rows.

[0057] Based on this, the embodiments of this application realize that the first type of sub-pixels and the second type of sub-pixels are arranged alternately in both the first and second directions, which can reduce the defects of horizontal and vertical stripes during display and improve the display quality.

[0058] In some embodiments, such as Figure 6As shown, the display panel also includes a first multiplexing circuit 501 and a second multiplexing circuit 502; the input terminal of the first multiplexing circuit 501 is electrically connected to the first data signal input terminal, and the multiple output terminals of the first multiplexing circuit 501 are electrically connected to multiple first data lines 201 in a one-to-one correspondence; the input terminal of the second multiplexing circuit 502 is electrically connected to the second data signal input terminal, and the multiple output terminals of the second multiplexing circuit 502 are electrically connected to multiple second data lines 202 in a one-to-one correspondence.

[0059] Here, during the data writing stage of a display frame, the driver chip transmits the data line signal to the first multiplexing circuit 501 through the signal input terminal of the first data line 201, and then transmits it to the corresponding first data line 201. Similarly, the driver chip can transmit the data signal to the second multiplexing circuit 502 through the second data signal input terminal, and then transmit it to the corresponding second data line 202.

[0060] This application embodiment achieves independent driving of the first and second type of sub-pixels by setting two sets of independent multiplexing circuits, thereby reducing driving costs.

[0061] In some embodiments, such as Figure 6 As shown, the first multiplexing circuit 501 includes a first transistor T1 and a second transistor T2. The first terminal of the first transistor T1 and the first terminal of the second transistor T2 are both electrically connected to the first data signal input terminal. The second terminal of the first transistor T1 and the second terminal of the second transistor T2 are electrically connected to any two first data lines 201 in a one-to-one correspondence. The second multiplexing circuit 502 includes a third transistor T3 and a fourth transistor T4. The first terminal of the third transistor T3 and the first terminal of the fourth transistor T4 are electrically connected to the second data signal input terminal. The second terminal of the third transistor T3 and the second terminal of the fourth transistor T4 are electrically connected to any two second data lines 202 in a one-to-one correspondence. The control terminals of the first transistor T1 and the third transistor T3 are electrically connected to the first control line S1. The control terminals of the second transistor T2 and the fourth transistor T4 are both electrically connected to the second control line S2.

[0062] It is conceivable that, based on the above connection method, when the first control line S1 outputs an enable level, the first transistor T1 and the third transistor T3 are turned on, and the data signal at the first data signal input terminal can be written to the corresponding first data line 201, and the data signal at the second signal input terminal can be written to the corresponding second data line 202; when the second control line S2 outputs an enable level, the second transistor T2 and the fourth transistor T4 are turned on, and the data signal at the first data signal input terminal can be written to the corresponding first data line 201, and the data signal at the second signal input terminal can be written to the corresponding second data line 202.

[0063] The embodiments of this application control the first transistor and the third transistor simultaneously based on the first control line, and control the second transistor and the fourth transistor simultaneously based on the second control line. This can reduce the number of control lines, free up wiring space, and enable the first type of sub-pixels and the second type of sub-pixels to obtain grayscale voltage synchronously, thereby improving display consistency and uniformity.
