[ field of technology ]
The present invention relates to the field of display technologies, and in particular, to a display panel rendering method, a display panel, and a display device.
[ background Art ]
In the existing display technology, by adopting the scheme of an under-screen optical device, the optical device is arranged below a display area, so that the space of a non-display area is saved, and the screen occupation ratio is improved to realize a comprehensive screen. Taking an optical device as a camera as an example, when a picture is normally displayed, the area where the camera is located can be normally displayed; when the camera is started, light rays penetrate through the display panel and are collected by the camera, so that a photographing or shooting function is realized.
Since the light-transmitting area in the display area is limited, in order to increase the light transmittance, the optical performance of the optical device under the screen is improved, and the conventional arrangement mode is to reduce the pixel density of the area where the optical device is located. And the reduced pixel density in the area where the optical device is located will result in reduced brightness in that area. In the prior art, the problem of brightness reduction caused by the reduction of pixel density is compensated by improving the brightness of a single sub-pixel in the area, so that the brightness uniformity of the whole display area is realized. After the brightness of a single sub-pixel in the area where the optical device is located is improved, a bright line exists at the junction of the area where the optical device is located and the normal display area during display, so that the split screen influences the display effect.
[ invention ]
In view of the above, the present invention provides a display panel rendering method, a display panel and a display device, which are used for solving the problem of split display in the prior art and improving the display effect.

the display area comprises a first display area and a second display area;
the sub-pixels comprise first sub-pixels and second sub-pixels, the first sub-pixels are positioned in a first display area, the second sub-pixels are positioned in a second display area, and the second display area is multiplexed into an optical device area;
the rendering method comprises the following steps:
the first display area is displayed in a subpixel rendering mode, and the first subpixels adjacent to the second display area do not use the second subpixels to display white.
In a second aspect, based on the same inventive concept, the present invention further provides a display panel, and any one of the rendering methods provided by the present invention is adopted for display.
In a third aspect, the present invention also provides a display device, including any one of the display panels provided by the present invention, based on the same inventive concept.
The rendering method of the display panel, the display panel and the display device provided by the invention have the following beneficial effects: when displaying the picture, the first sub-pixel and the second sub-pixel which are positioned near the boundary position of the first display area and the second display area do not need to form a complete display pixel by mutual borrowing. When the picture is displayed, the display pixels formed by the first sub-pixels and the second sub-pixels are not existed, the bright line problem is not generated at the junction position of the first display area and the second display area, and the display effect is improved.

[ detailed description ] of the invention
For a better understanding of the technical solution of the present invention, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.
It should be understood that the described embodiments are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one relationship describing the association of the associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
In the organic light emitting display panel, the separation distance between adjacent sub-pixels of different colors cannot be too small due to process limitations, thereby also limiting the improvement of the resolution of the display panel. In the related art, a subpixel rendering (Sub Pixel Rendering or SPR) manner is generally used to perform display, so that the visual display effect is improved without changing the actual resolution of the panel. The sub-pixel rendering technology realizes the improvement of the sense resolution by enabling the adjacent pixels to share partial sub-pixels, so that the sense resolution can be improved under the condition that the arrangement density of the sub-pixels is unchanged. The inventors consider that: when the sub-screen optical device scheme is applied to the display panel for displaying by adopting the sub-pixel rendering mode, the problem of bright lines at the junction of the area where the optical device is positioned and the normal display area can occur. Fig. 1 is a schematic diagram of a display panel in the related art. As shown in fig. 1, portions of a first display area AA1 ' and a second display area AA2 ' are illustrated, the second display area AA2 ' having a pixel density less than that of the first display area AA1 ', the display areas including sub-pixels sp1 ', sp2 ' and sp3 ' of three different colors. After the display area is divided, the arrangement mode of the sub-pixels in the first display area AA1 'is schematically shown in the figure, and after the original image data is processed by the sub-pixel rendering mode, the display picture comprises a transition pixel p″ when being displayed, wherein the transition pixel p″ comprises a sub-pixel sp 1' and a sub-pixel sp2 'which are positioned in the first display area AA 1', and a sub-pixel sp3 'which is positioned in the second display area AA 2'. Since the brightness of the single sub-pixel within the second display area AA2 'has been increased in order to ensure the uniformity of the overall brightness of the display area of the display panel, the brightness of the single sub-pixel of the transition pixel P "located within the second display area AA 2' becomes large, which may cause the brightness of the transition pixel P" to be greater than that of other pixels in the display screen, thereby causing bright lines to appear at the transition positions of the first display area AA1 'and the second display area AA 2'.
Based on the above, the inventor provides a rendering method of a display panel, a display panel and a display device, and under the condition that the display area is still displayed by adopting a sub-pixel rendering mode, the sub-pixels in the normal display area do not use the sub-pixels in the corresponding area of the camera to form a pixel unit, so that the problem of bright lines at the junction position of the two areas is avoided, and the display effect is improved.
An embodiment of the invention provides a rendering method of a display panel, and fig. 2 is a partial schematic diagram of an alternative implementation of the display panel displayed by adopting the rendering method provided by the embodiment of the invention. As shown in fig. 2, the display panel includes a display area AA, and the display area AA includes a first display area AA1 and a second display area AA2; a sub-pixel sp, the sub-pixel sp including a first sub-pixel 1sp and a second sub-pixel 2sp, the first sub-pixel 1sp being located in the first display area AA1 and the second sub-pixel 2sp being located in the second display area AA2, as illustrated in the figure, the first sub-pixel 1sp including a first color first sub-pixel 1sp1, a second color first sub-pixel 1sp2, and a third color first sub-pixel 1sp3; the second sub-pixel 2sp includes a first color second sub-pixel 2sp1, a second color second sub-pixel 2sp2, and a third color second sub-pixel 2sp3. The pixel density of the second display area AA2 is smaller than that of the first display area AA1, wherein the pixel density is the number of pixels per inch of screen. When the display panel is assembled into the display device, the optical device can be arranged at the position corresponding to the second display area, so that the scheme of the optical device under the screen is realized. The optical device may be, for example, a fingerprint sensor, a camera, etc.
The display panel for displaying by adopting the rendering method provided by the embodiment of the invention is provided with the function of increasing the brightness of a single second sub-pixel to compensate the brightness reduction problem caused by the reduction of the pixel density of the second display area. When a frame of picture is displayed, the brightness of the single second sub-pixel is larger than that of the single first sub-pixel, so that the brightness of the second display area is approximately the same as that of the first display area.
The rendering method provided by the embodiment of the invention comprises the following steps: the first display area AA1 adopts a subpixel rendering mode to display, and the first subpixel 1sp adjacent to the second display area AA2 does not use the second subpixel 2sp to display white. According to the principle of color development, when white display is formed, at least a red-light-emitting subpixel, a green-light-emitting subpixel, and a blue-light-emitting subpixel are included in the display pixel. As illustrated in fig. 2, when the rendering method provided by the present invention is used for displaying, after the sub-pixel rendering mode processing is performed on the original image data, three sub-pixels sp in the adjacent positions of the first display area AA1 and the second display area AA2 can form a complete display pixel P when the display screen is displayed. That is, when displaying the image, the first sub-pixel and the second sub-pixel located near the boundary position of the first display area and the second display area do not need to form a complete display pixel by mutual borrowing. When the picture is displayed, the display pixels (namely, transition pixels in the related art) formed by the first sub-pixels and the second sub-pixels are not included, so that the bright line problem is not generated at the junction position of the first display area and the second display area, and the display effect is improved.
In understanding the embodiments of the present invention, it is necessary to understand the relationship of display pixels and sub-pixels. In the display panel for displaying by adopting the sub-pixel rendering mode, the display pixel defined by the embodiment of the invention is a minimum display unit in the display picture of the display panel when displaying by adopting the sub-pixel rendering mode. The sub-pixels are actually arranged in the display panel.
The invention is not limited to the arrangement mode of the sub-pixels in the first display area and the arrangement mode of the sub-pixels in the second display area. Fig. 2 illustrates in principle only one alternative arrangement of sub-pixels. In an actual display panel, the arrangement modes of the sub-pixels are different, and the display panel can apply different sub-pixel rendering modes. In different sub-pixel rendering methods, the number of sub-pixels corresponding to one display pixel is also different during display, and in the description of the embodiment of the invention, three sub-pixels with different colors form one display pixel to illustrate the principle of the invention. In practice, for different sub-pixel rendering modes and sub-pixel arrangement modes, more than three sub-pixels may form a display pixel.
In the display, the implementation manner that the first sub-pixel adjacent to the second display area does not borrow the second sub-pixel to perform white display comprises the following steps: the first sub-pixels adjacent to the second display area are used for white display by other first sub-pixels adjacent to the first sub-pixels, namely, when the first sub-pixels are processed by a sub-pixel rendering algorithm and displayed, a plurality of first sub-pixels adjacent to the second display area can form a complete display pixel; the first display area and the second display area are arranged near the boundary position of the first display area and the second display area, and the first sub-pixel is arranged to display white by the first sub-pixel during display, so that the first sub-pixel is prevented from displaying white by the second sub-pixel during display, wherein the borrowed sub-pixel is not used as a pixel for display and is only used for borrowing the first sub-pixel during the formation of the display pixel. The following embodiments will illustrate in detail an implementation manner in which a first subpixel adjacent to a second display area does not use a second subpixel to perform white display, and the embodiments of the present invention include, but are not limited to, the following embodiments.
In some optional implementations, the rendering method provided by the embodiment of the invention includes: a virtual boundary is arranged between the first display area and the second display area, borrowed sub-pixels are arranged on one side, close to the first display area, of the virtual boundary, and white display is carried out by the borrowed sub-pixels of the first sub-pixels adjacent to the second display area. By setting the borrowing sub-pixel, the borrowing sub-pixel is only used as borrowing, and the first sub-pixel adjacent to the virtual boundary is ensured to display white without the second sub-pixel. In a display panel for displaying by adopting a sub-pixel rendering mode, a display area generally comprises a plurality of repeated units, and the regular arrangement of sub-pixels is realized through the arrangement of the repeated units so as to be matched with the corresponding sub-pixel rendering mode. In some embodiments, adjacent to the virtual boundary is an incomplete repeating unit, and borrowing sub-pixels need to be disposed between the incomplete repeating unit and the virtual boundary; in some embodiments, adjacent to the virtual boundary is a complete repeating unit, and borrowing sub-pixels need to be disposed between the repeating unit and the virtual boundary to ensure that a first sub-pixel within the repeating unit does not borrow a second sub-pixel for white display. Additionally, the shape of the virtual boundary may be substantially straight in some embodiments; the shape of the virtual boundary may be a curve in some embodiments; in some embodiments, two virtual boundaries whose extending directions intersect each other may be included in one display panel. The following examples will illustrate specific embodiments.
In the display panel for displaying by adopting the rendering method provided by the embodiment of the invention, when the first display area is displayed by adopting the sub-pixel rendering mode, the borrowing direction of the first sub-pixel in the first display area is intersected with the extending direction of the virtual boundary, and the borrowing sub-pixel is arranged on one side of the virtual boundary, which is close to the first display area, so that the first sub-pixel adjacent to the second display area is ensured to display in white by the borrowing sub-pixel. The borrowing direction refers to a direction of a sub-pixel that the first sub-pixel needs to borrow for displaying relative to the first sub-pixel.
In some optional implementations, in the display panel for displaying by using the rendering method provided by the embodiment of the present invention, the first display area includes a plurality of repeating units, one repeating unit includes at least N first sub-pixels, and the N first sub-pixels include three first sub-pixels with different emission colors, where N is an integer, and N is greater than or equal to 4; alternatively, n=4, or n=6, or n=12, and in practice, the repeating units of the display area may be designed according to a specific subpixel rendering calculation method adopted by the display panel. The rendering method further includes: a virtual boundary is arranged between the first display area and the second display area, the first display area further comprises incomplete repeated units adjacent to the virtual boundary, and the number of first sub-pixels in the incomplete repeated units is smaller than N; and setting borrowing sub-pixels between the incomplete repeating units and the virtual boundary, wherein at least part of first sub-pixels in the incomplete repeating units are borrowed by the borrowing sub-pixels to display white. The embodiment provides a way of adding the borrowing sub-pixel to ensure that the first sub-pixel adjacent to the second display area does not display white by the second sub-pixel during display.
In one embodiment, the incomplete repeating unit includes a first incomplete repeating unit, the number of first sub-pixels in the first incomplete repeating unit is M1, wherein M1 is a positive integer and M1< N, N1 borrowed sub-pixels are disposed between the first incomplete repeating unit and the virtual boundary, N1 is an integer and N1 is greater than or equal to 1, wherein m1+n1< N. After setting n1 borrowed sub-pixels, part of the first sub-pixels in the first incomplete repeating unit are borrowed to display white, and the borrowed sub-pixels and the first sub-pixels in the first incomplete repeating unit cannot form a complete repeating unit. Specifically, taking an example that one repeating unit includes 6 first sub-pixels, fig. 3 is a schematic partial diagram of another alternative implementation of a display panel that uses the rendering method provided by the embodiment of the present invention to display. As shown in fig. 3, one repeating unit CC includes 6 first sub-pixels 1sp (i.e., n=6 in this embodiment). The first subpixel 1sp includes a first color first subpixel 1sp1, a second color first subpixel 1sp2, and a third color first subpixel 1sp3; the first incomplete repetitive unit 1FCC adjacent to the virtual boundary XB includes 2 first sub-pixels (i.e., m1=2 in this embodiment). Between the first incomplete repeating unit 1FCC and the virtual boundary XB, 1 borrowed subpixel Jsp is set (i.e., n1=1 in this embodiment). In the display, the first color first sub-pixel 1sp1 and the second color first sub-pixel 1sp2 in the first incomplete repeating unit 1FCC display white by borrowing the sub-pixel Jsp, as illustrated in the figure, above the first sub-pixels in the first incomplete repeating unit 1FCC, i.e. the borrowing direction of the first sub-pixel 1sp in this example is the second direction y in the figure, the extending direction of the virtual boundary XB is substantially the first direction x, and the first direction x and the second direction y intersect each other. That is, during display, the first sub-pixel adjacent to the virtual boundary XB does not need the second sub-pixel to perform white display, so that the problem that bright lines cannot be generated at the junction position of the first display area and the second display area is avoided, and the display effect is improved.
It should be noted that, in the embodiment of the present invention, the definition and division of the corresponding repeating units and/or the incomplete repeating units are only for illustrating the difference between the arrangement of the first sub-pixels adjacent to the virtual boundary in the first display area and the arrangement of the first sub-pixels in other areas in the first display area. The division of the repeating units is not necessarily related to the subpixel rendering algorithm employed by the display panel. When the display is performed by adopting the subpixel rendering mode, the first subpixel in the repeating unit can not necessarily only display white by using the first subpixel belonging to the same repeating unit, that is, in some embodiments, part of the first subpixels in the repeating unit can display white by using the first subpixels in the repeating unit adjacent to the first subpixels in the repeating unit during the display.
In another embodiment, taking the example that one repeating unit CC illustrated in fig. 3 includes 6 first sub-pixels 1sp, when 1 first sub-pixel is included in a first incomplete repeating unit adjacent to a virtual boundary, in a display panel that performs display by using the rendering method provided by the embodiment of the present invention, 2 borrowed sub-pixels may be disposed between the first incomplete repeating unit and the virtual boundary, and during display, the first sub-pixel in the first incomplete repeating unit and the 2 borrowed sub-pixels form one display pixel.
In one embodiment, the incomplete repeating unit includes a second incomplete repeating unit, and the number of the first sub-pixels in the second incomplete repeating unit is M2, where M2 is a positive integer, and M2< N; and setting N2 borrowed sub-pixels between the second incomplete repeating unit and the virtual boundary, wherein N2 is an integer, and N2 is more than or equal to 1, wherein M2+n2=N. After n2 borrowed sub-pixels are set, part of the first sub-pixels in the second incomplete repeating unit are borrowed to display white, and the borrowed sub-pixels and the first sub-pixels in the second incomplete repeating unit form a complete repeating unit. Specifically, taking an example that one repeating unit includes 6 first sub-pixels, fig. 4 is a partial schematic diagram of another alternative implementation of a display panel that uses the rendering method provided by the embodiment of the present invention to display. As shown in fig. 4, one repeating unit CC includes 6 first sub-pixels 1sp (i.e., n=6 in this embodiment). The first subpixel 1sp includes a first color first subpixel 1sp1, a second color first subpixel 1sp2, and a third color first subpixel 1sp3; the second incomplete repeat unit 2FCC adjacent to the virtual boundary XB includes 4 first sub-pixels (i.e., m2=4 in this embodiment). Between the second non-repeating unit 2FCC and the virtual boundary XB, 2 borrowed sub-pixels Jsp (i.e., n2=2, m2+n2=6 in this embodiment) are set. The borrowed sub-pixels Jsp as illustrated in the figure are located above them with respect to the first sub-pixels in the second incomplete repeating unit 2FCC, i.e. the borrowing direction of the first sub-pixels 1sp in this example is the second direction y in the figure, the extending direction of the virtual boundary XB is substantially the first direction x, which intersects the second direction y. Optionally, during display, the second color first sub-pixel 1sp21 in the second non-repeating unit 2FCC and the first color first sub-pixel 1sp1 and the third color first sub-pixel 1sp3 adjacent to the second color first sub-pixel 1sp, and at the same time, the second color first sub-pixel 1sp21 in the second non-repeating unit 2FCC and the two borrowed sub-pixels Jsp may form a display pixel, so that white can be displayed. The two borrowed sub-pixels Jsp are used only as borrowing, and the two borrowed sub-pixels Jsp are not used alone as display pixels. The first sub-pixel 1sp2 with the second color does not need to use the second sub-pixel 2sp to perform white display, namely, when in display, the first sub-pixel adjacent to the virtual boundary XB does not need the second sub-pixel to perform white display, so that the problem that bright lines cannot be generated at the junction position of the first display area and the second display area is avoided, and the display effect is improved.
In another embodiment, taking the example that one repeating unit CC illustrated in fig. 4 includes 6 first sub-pixels 1sp, when 5 first sub-pixels are included in a second incomplete repeating unit adjacent to a virtual boundary, in a display panel that performs display by using the rendering method provided by the embodiment of the present invention, 1 borrowed sub-pixel may be disposed between the second incomplete repeating unit and the virtual boundary, and when displaying, a portion of the first sub-pixels in the second incomplete repeating unit and 1 borrowed sub-pixel form one display pixel.
In some optional embodiments, the virtual boundary between the first display area and the second display area is approximately a straight line, and in a display panel including an incomplete repeating unit, a display panel that uses the rendering method provided by the embodiment of the present invention to display a white color may be configured between the incomplete repeating unit and the virtual boundary by setting a borrowed pixel row or a borrowed pixel column that has the same extending direction as the virtual boundary, so as to implement that the first sub-pixel in the non-repeating unit displays the white color by borrowing the sub-pixel.

The problem that bright lines cannot be generated at the junction position of the first display area and the second display area is avoided, and the display effect is improved.
In another embodiment, fig. 6 is a partial schematic diagram of another alternative implementation of a display panel displayed by using the rendering method provided in the embodiment of the present invention.

In this embodiment, the virtual boundary is a curve, or a straight line intersecting both the first direction and the second direction, and is schematically shown as a curve in fig. 6. When the extending direction of the virtual boundary is crossed with the first direction and the second direction, a row of borrowed sub-pixels are arranged in the first display area along the extending direction of the virtual boundary, so that the first sub-pixels can display white by the borrowed sub-pixels during display, and the borrowed sub-pixels are only used as borrows and are not independently used as display pixels for display.
In an embodiment, fig. 7 is a partial schematic diagram of another alternative implementation of a display panel displayed by using the rendering method provided by the embodiment of the present invention. As shown in fig. 7, in the embodiment corresponding to fig. 3, the repeating units CC in the first display area AA1 are the same, in fig. 7, the repeating units CC adjacent to the virtual boundary XB are complete repeating units CC, and borrowed sub-pixels Jsp are disposed between the repeating units CC and the virtual boundary XB, so that two first sub-pixels 1sp in the repeating units CC and close to the virtual boundary XB can form one display pixel P5 by borrowing the borrowed sub-pixels Jsp. The borrowing direction of the first subpixel 1sp illustrated in fig. 7 is the second direction y in the drawing, and the extending direction of the virtual boundary XB is substantially the first direction x, and the first direction x and the second direction y intersect each other. Optionally, when displaying in the first display area by adopting a subpixel rendering mode, the first subpixels in the complete repeating unit also need to form display pixels by using subpixels adjacent to the first subpixels, at this time, the rendering method provided by the embodiment of the invention is adopted for displaying, and borrowed subpixels Jsp are arranged between the complete repeating unit CC and the virtual boundary XB, so that it is ensured that part of the first subpixels in the complete repeating unit CC form display pixels by borrowing subpixels, and white display can be performed.
In some optional implementations, when the display panel displaying by adopting the rendering method provided by the embodiment of the present invention sets the borrowed sub-pixel to realize that the first sub-pixel adjacent to the second display area does not display white by using the second sub-pixel, the light emitting area of the borrowed sub-pixel is S1, the light emitting area of the first sub-pixel with the same light emitting color as the borrowed sub-pixel is S2, and s1=s2. In this embodiment, it is possible to ensure that the color of the display does not suffer from color shift when the first sub-pixel is displayed by the display pixel constituted by the borrowed sub-pixel.
In some optional implementations, in the display panel for displaying by using the rendering method provided by the embodiment of the present invention, a virtual boundary is provided between the first display area and the second display area, and the repeating units at positions adjacent to the virtual boundary in the first display area are all complete repeating units, where one repeating unit includes at least N first sub-pixels, and the N first sub-pixels include three first sub-pixels with different light emission colors, where N is an integer, and N is greater than or equal to 4. The first sub-pixels adjacent to the virtual boundary constitute one display pixel by means of mutual borrowing, and the second sub-pixels located in the second display area are not required, and this embodiment can be applied to a case where the borrowing direction of the first sub-pixels is substantially the same as the extending direction of the virtual boundary when displaying by using the sub-pixel rendering method. The method can be realized by mutually matching the arrangement mode of the sub-pixels in the display panel and the rendering mode of the sub-pixels, and the sub-pixels do not need to be additionally arranged.
In an embodiment, fig. 8 is a partial schematic diagram of another alternative implementation of a display panel displayed by using the rendering method provided by the embodiment of the present invention. As shown in fig. 8, there is a virtual boundary XB between the first display area AA1 and the second display area AA2, and the repeating units CC at positions adjacent to the virtual boundary XB within the first display area AA1 are all complete repeating units. As illustrated in the figure, one repeating unit CC includes 4 first sub-pixels 1sp as an example, and the first sub-pixels 1sp include first color first sub-pixels 1sp1, second color first sub-pixels 1sp2, and third color first sub-pixels 1sp3. As illustrated in the figure, a first direction x and a second direction y intersecting each other. In the first display area AA1, as illustrated in the figure, two adjacent first-color first sub-pixels 1sp1 and third-color first sub-pixels 1sp3 can form a display pixel P1 by one second-color first sub-pixel 1sp2 adjacent to the left side (i.e., adjacent in the first direction x in the figure), so as to perform white display; the display pixel P2 can be constituted by one second color first subpixel 1sp2 adjacent to the right side (i.e., adjacent in the first direction x in the figure), and white display can be performed. That is, in this example, the borrowing direction of the first subpixel 1sp is the first direction x in the figure, the extending direction of the virtual boundary XB is substantially the first direction x, and the borrowing direction of the first subpixel is substantially the same as the extending direction of the virtual boundary. In this embodiment, the first sub-pixel 1sp adjacent to the virtual boundary XB performs white display by using the first sub-pixel 1sp of the other color adjacent to the virtual boundary XB in the first direction x, and does not use the second sub-pixel 2sp adjacent to the first sub-pixel in the second direction y. By designing the arrangement mode and the rendering mode of the sub-pixels in the first display area, the first sub-pixels adjacent to the virtual boundary can be prevented from carrying out white display by the second sub-pixels, and the problem that bright lines cannot be generated at the junction position of the first display area and the second display area is avoided
In another embodiment, fig. 9 is a partial schematic diagram of another alternative implementation of a display panel displayed by using the rendering method provided in the embodiment of the present invention. As shown in fig. 9, the repeating units CC at positions adjacent to the virtual boundary XB within the first display area AA1 are all complete repeating units. As illustrated in the figure, one repeating unit CC includes 4 first sub-pixels 1sp as an example, and the first sub-pixels 1sp include first color first sub-pixels 1sp1, second color first sub-pixels 1sp2, and third color first sub-pixels 1sp3. As illustrated in the figure, a first direction x and a second direction y intersecting each other. As illustrated in the figure, a pixel borrowing method is taken as an example at the time of display. The first-color first sub-pixel 1sp11 can be borrowed by two first sub-pixels 1sp1 on the left side (i.e., adjacent thereto in the first direction x) to constitute a display pixel P3, and white display can be performed; the first color first sub-pixel 1sp11 can be borrowed by two first sub-pixels 1sp1 on the right side (adjacent thereto in the first direction x) to constitute a display pixel P4, and white display can be performed. That is, in this example, the borrowing direction of the first subpixel 1sp is the first direction x in the figure, the extending direction of the virtual boundary XB is substantially the first direction x, and the borrowing direction of the first subpixel is substantially the same as the extending direction of the virtual boundary. In this embodiment, as in the embodiment illustrated in fig. 8, the first sub-pixel 1sp adjacent to the virtual boundary XB performs white display by using the first sub-pixel 1sp of the other color adjacent to the virtual boundary XB in the first direction x, and does not use the second sub-pixel 2sp adjacent thereto in the second direction y. By designing the arrangement mode of the sub-pixels and the rendering mode of the sub-pixels in the first display area, the first sub-pixels adjacent to the virtual boundary can be prevented from performing white display by the second sub-pixels, and the problem that bright lines cannot be generated at the junction position of the first display area and the second display area is avoided.
For the arrangement of the sub-pixels in the first display area illustrated in fig. 9, the pixel borrowing manner during display may also be: the first color first sub-pixel 1sp1 and the second color first sub-pixel 1sp2 adjacent to each other in the second direction y perform white display by the third color first sub-pixel 1sp3 adjacent to each other in the first direction x. That is, the borrowing direction of the first subpixel 1sp is the first direction x, the extending direction of the virtual boundary XB is substantially the first direction x, and the borrowing direction of the first subpixel is substantially the same as the extending direction of the virtual boundary. The borrowing mode can not use the second sub-pixel, and bright line problem can not be generated at the junction position of the first display area and the second display area.

During display, the first sub-pixel 1sp and a part of the first sub-pixel 1sp close to the virtual boundary XB are subjected to white display by virtue of the borrowed sub-pixel Jsp, so that the first sub-pixel 1sp cannot be subjected to white display by virtue of the second sub-pixel 2sp, wherein the borrowed sub-pixel Jsp is only used as borrowing, and is not used as a display pixel for display. So that bright lines at the boundary between the first display area AA1 and the second display area AA2 can be prevented.
