Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example one
Fig. 1 and fig. 2 are schematic structural diagrams of a display panel according to an embodiment of the present invention, as shown in fig. 1 and fig. 2, the display substrate has a first display area 10 and a second display area 20, and the display panel includes a plurality of repeating units arranged in an array; the repeating unit located in the first display area 10 is a first repeating unit 101; the repeating unit located in the second display area 20 is a second repeating unit 201; the first repeating unit 101 and the second repeating unit 201 each include: two rows and four columns of sub-display regions; each sub-display area in the first repeating unit 101 is provided with sub-pixels, and the four sub-pixels in the first row of sub-display areas are sequentially: a green sub-pixel G, a blue sub-pixel B, a green sub-pixel G and a red sub-pixel R; the four sub-pixels in the second row of sub-display regions are sequentially: a green sub-pixel G, a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B; at least some of the second repeating units 201 have sub-pixels disposed only in the second to fourth sub-display regions of the first row, and the three sub-pixels are a blue sub-pixel B, a green sub-pixel G, and a red sub-pixel R in this order.
In the display substrate provided in the embodiment of the present invention, a row of green sub-pixels G, a row of blue sub-pixels B, a row of green sub-pixels G, a row of red sub-pixels R, a row of green sub-pixels G, a row of red sub-pixels R, a row of green sub-pixels G, and a row of blue sub-pixels B are disposed in two rows and four columns of first repeating units 101 of the first display area 10, and when two sub-pixels of different colors are lit during display, one adjacent sub-pixel of another color can be lit, and a multi-color display of a whole display screen can be achieved by adopting a pixel borrowing method, so that more pixel units including three sub-pixels of different colors can be displayed in the original two rows. In at least part of the second repeating unit 201 of the second display 20, only the second to fourth sub-display regions of the first row are provided with the blue sub-pixel B, the green sub-pixel G and the red sub-pixel R, and the other sub-display regions are in transparent arrangement, so that three sub-pixels with different colors can be lighted up by one pixel unit during display, and the rest positions are transparent, thereby reducing the pixel density of the second display region 20, and realizing the partial transparent display of the second display region 20. In practical application, optical sensors such as a camera and an infrared sensor can be arranged at transparent positions in the second display area 20 of the display panel, so that the display function can be realized, the requirement of an optical sensing device on the light transmittance can be met, the optical sensing device can be prevented from occupying the display space, the screen occupation ratio of the display panel can be improved, full-screen display can be realized, and the user experience is improved.
In one possible implementation, as shown in fig. 1, a row of green, blue, green and red sub-pixels G, B, G and R, and a row of green, red, green and blue sub-pixels G, R are disposed in two rows and four columns of sub-display regions of each first repeating unit 101 of the first display region 10. During displaying, in the two rows and four columns of sub-display areas of the first repeating unit 101 in the first display area 10, the display of 8 pixel units including three sub-pixels with different colors can be realized by adopting a pixel borrowing manner (as shown by connecting lines in the figure). Only the second to fourth sub-display regions of the first row in all the second repeating units 201 of the second display 20 are provided with the blue sub-pixel B, the green sub-pixel G, and the red sub-pixel R, and the other sub-display regions are provided in a transparent state. In displaying, in two rows and four columns of sub-display regions of the second repeating unit 201 of the second display region 20, a display of a pixel unit including three sub-pixels of different colors can be realized. It can be seen that the pixel density in the second display area 20 is much lower than the pixel density in the first display area 10, so that the local transparent display can be realized in the second display area 20 of the display panel, and the good light transmittance is ensured, so that the requirement of the optical sensing device on light can be met, the display space occupied by the optical sensing device can be avoided, and the screen occupation ratio of the display panel can be improved.
In another possible implementation manner, as shown in fig. 2, a row of green, blue, green and red sub-pixels G, G and R, and a row of green, red, green and blue sub-pixels G, R, G and R are disposed in two rows and four columns of sub-display regions of each first repeating unit 101 of the first display region 10. In only one second repeating unit 201 of the second display 20, only the second to fourth sub-display regions of the first row are provided with the blue sub-pixel B, the green sub-pixel G, and the red sub-pixel R, and the other sub-display regions are provided in a transparent state. The implementation principle is similar to that in the above implementation manner, and is not described herein again.
In the embodiment of the present invention, in addition to the above-mentioned pixel arrangement, the display panel further needs a corresponding driving circuit to provide a driving signal to each sub-pixel in the first display area 10 and the second display area 20 to implement display, and the following will describe the display panel with the pixel arrangement shown in fig. 1 in detail with reference to the accompanying drawings.

It should be noted that, the sub-pixels are disposed in two rows of the sub-display regions in the first repeating unit 101 of the first display region 10, and the gate driving circuit GOA may be disposed corresponding to each row of the sub-display regions by using a wiring manner of a driving circuit in the prior art, so that the gate driving circuit GOA may control the sub-pixels in each row by using one gate line. Only the first row of sub-display regions among the two rows of sub-display regions in the second repeating unit 201 of the second display 20 is provided with sub-pixels. In the embodiment of the invention, only the first row of sub-display regions is correspondingly provided with the gate driving circuit GOA, and the second row of sub-display regions is correspondingly provided with the redundant gate driving circuit Dummy GOA.

When displaying, the gate driving circuit GOA can input gate driving signals to the sub-pixels of each row line by line according to a preset time sequence to control the switching transistors in the sub-pixels of each row to be turned on, the redundant gate driving circuit Dummy GOA does not work, at this time, the source driving circuit can input corresponding source driving signals to the sub-pixels of each column by adopting the GGRB algorithm, and thus, the driving of each sub-pixel in the whole display panel is realized. Since the red sub-pixels R and the blue sub-pixels B in each row of the sub-display regions in the first display region 10 are distributed in a staggered manner, the red sub-pixels R in the same row and the blue sub-pixels B in the same row in the second display region 20 are distributed in different manners, in the process of refreshing the display image in the second display region 20, the source driving signal output by the source driving circuit needs to be changed by an algorithm, so that the source driving circuit inputs the corresponding source driving signal in the corresponding sub-display region, thereby realizing the normal display of the whole display image.

It should be noted that, the sub-pixels are disposed in two rows of the sub-display regions in the first repeating unit 101 of the first display region 10, and the gate driving circuit GOA may be disposed corresponding to each row of the sub-display regions by using a wiring manner of a driving circuit in the prior art, so that the gate driving circuit GOA may control the sub-pixels in each row by using one gate line.

In the embodiment of the invention, only the first row of sub-display regions is correspondingly provided with the gate driving circuit GOA, and the second row of sub-display regions is correspondingly provided with the redundant gate driving circuit Dummy GOA. Also, the blue sub-pixel B and the red sub-pixel R in different columns in the same second repeating unit 201 are cross-connected. The source driving circuit may control one column of green subpixels G through one data line and control the blue subpixels B and the red subpixels R cross-connected in different columns of the same second repeating unit 201 through one data line. When displaying, the gate driving circuit GOA can input gate driving signals to the sub-pixels of each row line by line according to a preset time sequence to control the switching transistors in the sub-pixels of each row to be turned on, the redundant gate driving circuit Dummy GOA does not work, at this time, the source driving circuit can input corresponding source driving signals to the blue sub-pixel B and the red sub-pixel R which are connected in a cross manner by adopting a GGRB algorithm, and thus, the driving of each sub-pixel in the whole display panel is realized.
Optionally, as shown in fig. 5, the display panel further includes: a gate driving circuit GOA and a source driving circuit (not shown in the figure).

It should be noted that, the sub-pixels are disposed in two rows of the sub-display regions in the first repeating unit 101 of the first display region 10, and the gate driving circuit GOA may be disposed corresponding to each row of the sub-display regions by using a wiring manner of a driving circuit in the prior art, so that the gate driving circuit GOA may control the sub-pixels in each row by using one gate line. Only the first row of sub-display regions among the two rows of sub-display regions in the second repeating unit 201 of the second display 20 is provided with sub-pixels. In the embodiment of the invention, the first row of sub-display regions and the second row of sub-display regions are respectively and correspondingly provided with the gate driving circuits GOA, and the gate driving circuits GOA corresponding to the second row of sub-display regions are suspended.
