In the prior art, an under-screen display panel is provided, i.e. an optical device (e.g. a camera) is arranged below the display screen. When photographing is needed, the display screen can become transparent glass, so that external light passes through the display screen to reach the camera, and when photographing is not needed, the display screen can normally display. However, since pixels are arranged below the region, light is diffracted by regularly arranged pixels when photographing. If the pixels have different angles and periods, diffraction is further deteriorated, starburst phenomenon is generated, and the photographing definition is affected.
In order to solve the above-mentioned technical problems, an embodiment of the present invention provides a display panel, and is shown in fig. 1 to 4, wherein fig. 1 is a schematic structural diagram of a display panel provided by an embodiment of the present invention, fig. 2 is a schematic structural diagram of a pixel arrangement of a second display area provided by an embodiment of the present invention, fig. 3 is a schematic structural diagram of a first pixel unit provided by an embodiment of the present invention, and fig. 4 is a schematic structural diagram of a second pixel unit provided by an embodiment of the present invention. Referring to fig. 1, a display area AA of the display panel 100 includes a first display area AA1 and a second display area AA2, wherein the first display area AA1 at least partially surrounds the second display area AA2, and the second display area AA2 corresponds to an optical device.
It is understood that the first display area AA1 at least partially encloses the second display area AA2. The area of the first display area AA1 is larger than that of the second display area AA2. The first display area AA1 is used for conventional display, and the second display area AA2 corresponds to an optical device. In the first state, the optical device is closed, and the second display area AA2 displays normally; in the second state, the optical device is turned on, and the second display area AA2 becomes transparent, so that light passes through the second display area AA2 to reach the optical device for imaging. The optics may be a camera or the like.
Further, referring to fig. 2, the second display area AA2 includes: a plurality of first pixel units 10 and second pixel units 20;
the first pixel units 10 and the second pixel units 20 are alternately arranged in sequence along the first direction x;
along the second direction y, the plurality of first pixel units 10 or the plurality of second pixel units 20 are sequentially and repeatedly arranged;
the first direction x and the second direction y intersect.
It is understood that the second display area AA2 includes the first pixel unit 10 and the second pixel unit 20. The first pixel unit 10 and the second pixel unit 20 are the smallest repeating units of the second display area AA2. The first pixel unit 10 and the second pixel unit 20 are repeatedly arranged along the first direction x, i.e., the row direction. Illustratively, the odd columns are the first pixel cells 10 and the even columns are the second pixel cells 20. Of course, the embodiment of the present invention is not limited to the first pixel unit 10 and the second pixel unit 20 being repeatedly arranged for one pixel unit. The two first pixel units 10 and the other second pixel unit 20 may be repeatedly arranged along the first direction x. The first pixel unit 10 or the second pixel unit 20 is repeatedly arranged in the second direction y, i.e., the column direction. Taking the first pixel unit 10 as an example, the first pixel unit 10 is on the same straight line along the second direction y, and the second pixel unit 20 is the same.
Referring to fig. 3, the first pixel unit 10 includes a color sub-pixel group 11 and a first sub-pixel group 12; the first sub-pixel group 12 is disposed on the first side y1 of the color sub-pixel group 11 along the second direction y, and the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12 intersects with the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11 along the second direction y, and the two extending directions are respectively the same as the angle formed by the first direction x.
Referring to fig. 4, the second pixel unit 20 includes a color sub-pixel group 11 and a second sub-pixel group 13; the second sub-pixel group 13 is arranged on the second side y2 of the color sub-pixel group 11 along the second direction y, the extending direction of the opening area of the sub-pixel included in the second sub-pixel group 13 is intersected with the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11 along the second direction y, and the two extending directions are respectively the same as the angle formed by the first direction x;
the first side y1 and the second side y2 are opposite sides of the second direction y; the extending direction of the opening regions of the sub-pixels included in the first sub-pixel group 12 is parallel to the extending direction of the opening regions of the sub-pixels included in the second sub-pixel group 13.
It will be appreciated that the first pixel unit 10 and the second pixel unit 20 include a color sub-pixel group 11 for displaying, and the first sub-pixel group 12 and the second sub-pixel 13 are used for improving the light transmittance of the second display area AA2 when the second display area AA2 is used for photographing.
In the first pixel unit 10, the first sub-pixel group 12 is located at a first side y1 of the color sub-pixel group 11 along the second direction y, and in the second pixel unit 20, the second sub-pixel group 13 is located at a second side y2 of the color sub-pixel group 11 along the second direction y, and the first side y1 and the second side y2 are opposite sides. Since the first sub-pixel group 12 and the second sub-pixel group 13 are disposed at different positions with respect to the color sub-pixel group 11, the projections of the color sub-pixel group 11 in the first pixel unit 10 and the color sub-pixel group 11 in the second pixel unit 20 do not overlap in the first direction x and the second direction y. Since the second display area AA2 is mainly color-displayed by the color sub-pixel group 11 in the first state, the first sub-pixel group 12 and the second sub-pixel group 13 are not displayed or are partially displayed. The staggered design of the color sub-pixel groups 11 can improve the uniformity of the display of the second display area AA2 in the first state, and improve the display effect. Meanwhile, along the first direction x, the projections of the first sub-pixel group 12 and the second sub-pixel group 13 are not completely overlapped, so that a large area dark band can be avoided during display.
Further, the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12 is different from the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11, and has a certain included angle. The extending direction of the opening regions of the sub-pixels included in the first sub-pixel group 12 is the same as the angle formed by the extending direction of the opening regions of the sub-pixels included in the color sub-pixel group 11 and the first direction x, i.e. symmetrical with respect to the first direction x. The first sub-pixel group 12 includes the sub-pixels having the opening regions with the first direction x at the first angle θ, which is counterclockwise, and the color sub-pixel group 11 includes the sub-pixels having the opening regions with the first direction x at the first angle θ, which is clockwise. The extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12 and the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11 are not parallel to the first direction x or the second direction y, and the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12 and the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11 are also different. Thus, the parallel edges of the patterns caused by the same extending directions are avoided, and further enhancement of the diffraction phenomenon of light is avoided.
The design of the extending direction of the opening area of the sub-pixel included in the second sub-pixel group 13 and the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11 refers to the above-described first sub-pixel 12 and color sub-pixel group 11.
Meanwhile, it should be noted that the extending direction of the opening regions of the sub-pixels included in the first sub-pixel group 12 is the same as the extending direction of the opening regions of the sub-pixels included in the second sub-pixel group 13. This is because the color sub-pixel group 11 has a color, and in the second state, the color sub-pixel 11 can transmit a limited amount of light. The second display area AA2 mainly relies on the first sub-pixel group 12 and the second sub-pixel group 13 to transmit light, so that the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12 is the same as the extending direction of the opening area of the sub-pixel included in the second sub-pixel group 13, which can reduce the trend of the edge of the image, reduce the direction of diffraction, and avoid the occurrence of starburst phenomenon.
In an alternative embodiment of the present invention, referring to fig. 5, fig. 5 is a schematic structural diagram of a color sub-pixel group according to an embodiment of the present invention. The color sub-pixel group 11 includes a first color sub-pixel 111, a second color sub-pixel 112, and a third color sub-pixel 113, and the light emission colors of the first color sub-pixel 111, the second color sub-pixel 112, and the third color sub-pixel 112 are different;
in the same color sub-pixel group 11, the first color sub-pixel 111, the second color sub-pixel 112, and the third color sub-pixel 113 are sequentially arranged along the first direction x.
It will be appreciated that the first color sub-pixel 111, the second color sub-pixel 112 and the third color sub-pixel 114 of the color sub-pixel group 11 emit light in different colors, and in particular, may be red, green and blue. The embodiment of the present invention is not limited to the specific emission color of each sub-pixel included in the color sub-pixel group 11, as long as the emission colors of the first color sub-pixel 111, the second color sub-pixel 112, and the third color sub-pixel 114 are all different. The color sub-pixel group 11 is mainly used for color display of the second display area AA2 in the second state. The different luminous intensities of the different sub-pixels can make the color sub-pixel group 11 display different colors to meet the display requirement of the second display area AA2.
Further, the first color sub-pixel 111, the second color sub-pixel 112, and the third color sub-pixel 113 are parallelograms and are sequentially arranged along the first direction x.
In an alternative embodiment provided by the present invention, the sub-pixels of the first sub-pixel group 12 and the second sub-pixel group 13 comprise white color resists or high transmittance film layers.
It will be appreciated that the sub-pixels of the first sub-pixel group 12 and the second sub-pixel group 13 comprise white color resist or high-permeability film layers. The white color resistance or the high-permeability film layer has higher transmittance. Therefore, in the first state, the second display area AA2 needs to be normally displayed, and the first sub-pixel group 12 and the second sub-pixel group 13 can increase the brightness of the second display area AA2. In the second state, the second display area AA2 is required to image the light received by the optical device, and the white color resist or high-transmittance film layer included in the first subpixel group 12 and the second subpixel group 13 can enable more light to pass through the display panel 100 to reach the optical device, so that the optical device can be imaged clearly.
In an alternative embodiment provided by the present invention, as shown in fig. 3 or fig. 4, the sum of the opening areas of the sub-pixels in the color sub-pixel group 11 is smaller than the sum of the opening areas of the sub-pixels in the first sub-pixel group 12 or the second sub-pixel group 13 in the same pixel unit.
It can be appreciated that the area of the second display area AA2 is much smaller than that of the first display area AA1, that is, the display panel 100 mainly depends on the first display area AA1 for displaying. The second display area AA2 only needs to have a certain color display function. More time, the second display area AA2 still needs to have higher light transmittance, so as to enable clear imaging when the optical device is turned on in the second state. While the color pixel group 11 is mainly used for color display, the first sub-pixel group 12 and the second sub-pixel group 113 are mainly used for light transmission. Therefore, the sum of the opening areas of the sub-pixels in the color sub-pixel group 11 is smaller than the sum of the opening areas of the sub-pixels in the first sub-pixel group 12 or the second sub-pixel group 13. Thereby improving the transmittance of the second display area AA2.
In an alternative embodiment provided by the present invention, as shown in fig. 3 or fig. 4, the length of the sub-pixels in the color sub-pixel group 11 along the second direction y is smaller than the length of the sub-pixels in the first sub-pixel group 12 or the second sub-pixel group 13 along the second direction y.
It will be appreciated that the length of the sub-pixels of the color sub-pixel group 11 in the first direction x is the same as the length of the sub-pixels of the first sub-pixel group 12 or the second sub-pixel group 13 in the first direction x. And the length of the sub-pixels in the color sub-pixel group 11 in the second direction y is smaller than the length of the sub-pixels in the first sub-pixel group 12 or the second sub-pixel group 13 in the second direction y. Therefore, the sum of the opening areas of the sub-pixels in the color sub-pixel group 11 is smaller than the sum of the opening areas of the sub-pixels in the first sub-pixel group 12 or the second sub-pixel group 13.
In an alternative embodiment of the present invention, referring to fig. 6, fig. 6 is a schematic structural diagram of another first pixel unit provided in the embodiment of the present invention, where the first sub-pixel group 12 includes three fourth sub-pixels 121;
the three fourth sub-pixels 121 are sequentially arranged in the first direction x, and in the second direction y, the fourth sub-pixels 121 overlap the first color sub-pixel 111, the second color sub-pixel 112, and the third color sub-pixel 113, respectively.
It will be appreciated that the first sub-pixel group 12 includes three fourth sub-pixels 121, and that the fourth sub-pixels 121 are parallelograms. The length of the fourth sub-pixel 121 along the first direction x is the same as the lengths of the first, second and third color sub-pixels 111, 112 and 113 along the first direction x, and the three fourth sub-pixels 121 overlap the first, second and third color sub-pixels 111, 112 and 113, respectively. Along the second direction y, the three fourth sub-pixels 121 respectively correspond to and overlap the first color sub-pixel 111, the second color sub-pixel 112, and the third color sub-pixel 113, which is advantageous for signal line wiring and convenient for manufacturing.
In an alternative embodiment provided by the present invention, the second pixel sub-group 12 is identical to the first sub-pixel group 13, as shown with reference to fig. 2 to 4.
It will be appreciated that the second pixel group 12 includes three fourth sub-pixels 121; the three fourth sub-pixels 121 are sequentially arranged in the first direction x, and in the second direction y, the fourth sub-pixels 121 overlap the first color sub-pixel 111, the second color sub-pixel 112, and the third color sub-pixel 113, respectively.
Similarly, in the second pixel unit 20, along the second direction y, the second sub-pixel group 113 includes three fourth sub-pixels 121 corresponding to and overlapping with the color sub-pixel group 11 including the first color sub-pixel 111, the second color sub-pixel 112 and the third color sub-pixel 113, so that the pixel arrangement structure is more regular, and the production and the manufacturing are convenient.
In an alternative embodiment of the present invention, reference is made to fig. 7 and 8, where fig. 7 is a schematic diagram of a pixel arrangement structure of another second display area provided in an embodiment of the present invention, and fig. 8 is a schematic diagram of a structure of another second pixel unit provided in an embodiment of the present invention. The second subpixel group 13 includes two fourth subpixels 121 and one fifth subpixel 131;
the fifth subpixel 131 and the two fourth subpixels 121 are sequentially arranged in the first direction x, and in the second direction y, the fifth subpixel 131 overlaps the first color subpixel 111.
It will be appreciated that in the embodiment provided by the present invention, the second subpixel group 13 includes one fifth subpixel 131 and two fourth subpixels 121. The shape of the fifth subpixel 131 is different from the shape of the fourth subpixel 121. Meanwhile, one fifth subpixel 131 and two fourth subpixels 121 are sequentially arranged in the first direction x such that the fifth subpixel 131 overlaps the first color subpixel 111 in the second direction y. Since the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12 of the first pixel unit 10 and the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11 are symmetrical with respect to the first direction x, there is a gap between the first pixel unit 10 and the second pixel unit 2. Since the first color sub-pixel 111 is adjacent to the adjacent first pixel unit 10 along the first direction, the fifth sub-pixel 131 overlaps the first color sub-pixel 111, so that the fifth sub-pixel 131 covers the gap between the first pixel unit 10 and the second pixel unit 20, the opening area of the fifth sub-pixel 131 is increased, and the opening ratio of the second display area AA2 is improved.
In an alternative embodiment provided by the present invention, with continued reference to FIG. 8, fifth subpixel 131 includes first side 1311;
the first side 1311 is a side of the fifth sub-pixel 131 near the first pixel unit 10, and the extending direction of the first side 1311 is at least partially parallel to the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11.
It will be appreciated that the fifth subpixel 131 is an irregular pattern and includes at least a first edge 1311. The first side 1311 is a side of the fifth subpixel 131 close to the first pixel unit 10, and the extending direction of the other sides of the fifth subpixel 131 is the same as the extending direction of the corresponding sides of the fourth subpixel 121. The extending direction of at least part of the first edge 1311 is parallel to the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12, and at least part of the extending direction of the first edge 1311 is parallel to the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11 in the first pixel unit 10, so that the opening area of the fifth sub-pixel 131 extends to be close to the first pixel unit 10. In this way, the fifth subpixel 131 can cover the gap between the first pixel unit 10 and the second pixel unit 20, and the opening area of the fifth subpixel 131 can be increased, thereby increasing the opening ratio of the second display area AA2.
In an alternative embodiment of the present invention, the opening area of the fifth subpixel 131 is larger than the opening area of the fourth subpixel 121.
It will be appreciated that since the fifth sub-pixel 131 includes the first edge 1311, the fifth sub-pixel 131 covers the gap between the first pixel cell 10 and the second pixel cell 20. Accordingly, the opening area of the fifth subpixel 131 is larger than that of the fourth subpixel 21. This can increase the aperture ratio of the second display area AA2, and can also increase the light transmittance of the second display area AA2 in the second state.
In an alternative embodiment of the present invention, reference is made to fig. 9 and 10, where fig. 9 is a schematic structural diagram of another display panel provided by an embodiment of the present invention, and fig. 10 is a schematic structural diagram of another display panel provided by an embodiment of the present invention, and each of the color sub-pixel group 11, the first sub-pixel group 12 and the second sub-pixel group 13 includes a plurality of sub-pixels; the display panel 100 further includes first electrodes 30 corresponding to the sub-pixels, respectively; the first electrode 30 comprises at least two electrode strips 31.

The first electrode 30 comprises at least two electrode strips 31. At least two electrode bars 31 are arranged along the first direction x. When the electrode bars 31 include two, the two electrode bars 31 are disposed near edges of the sub-pixels in the first direction x, respectively. When the electrode bars 31 include a plurality of electrode bars 31, the plurality of electrode bars 31 are uniformly distributed along the first direction x. The plurality of electrode bars 31 may be disposed within the opening regions of the sub-pixels, or may be disposed between adjacent sub-pixels along the first direction x.
In an alternative embodiment provided by the present invention, as shown in fig. 9 and 10, the extending direction of the first electrode 30 corresponding to the first sub-pixel group 12 and the second sub-pixel group 13 is the same as the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12.

It can be understood that, in the second state, the first subpixel group 12 and the second subpixel group 13 are mainly relied on to transmit light, so that the extending direction of the first electrode 30 opposite to the color subpixel group 11 is set to be the same as the extending direction of the opening area of the subpixels included in the first subpixel group 12, so that the number of wires and the liquid crystal deflection directions of the opening area of the subpixels can be reduced in the second state, thereby avoiding diffraction of light in multiple angles, avoiding occurrence of starburst phenomenon, and improving the imaging definition of the optical device in the second state.
In an alternative embodiment of the present invention, referring to fig. 12, fig. 12 is a schematic structural diagram of another display panel provided in an embodiment of the present invention, where an extending direction of a first electrode 30 opposite to a color sub-pixel group 11 included in a first pixel unit 10 is the same as an extending direction of an opening area of a sub-pixel included in the color sub-pixel group 11;
the extending direction of the first electrode opposite to the color sub-pixel group 11 included in the second pixel unit 20 is the same as the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12.
It can be understood that the extending direction of the first electrode 30 opposite to the color sub-pixel group 11 included in the first pixel unit 10 is the same as the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11; the extending direction of the first electrode opposite to the color sub-pixel group 11 included in the second pixel unit 20 is the same as the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12. In other words, the extending direction of the first electrode 30 corresponding to the color sub-pixel group 11 included in the first pixel unit 10 is different from the extending direction of the first electrode 30 corresponding to the color sub-pixel group 11 included in the second pixel unit 20.

In an alternative embodiment of the present invention, referring to fig. 13, fig. 13 is a schematic structural diagram of another display panel provided in an embodiment of the present invention, where an extending direction of a first electrode 31 opposite to a color sub-pixel group 11 included in a first pixel unit 10 is the same as an extending direction of an opening area of a sub-pixel included in a first sub-pixel group 12;
the extending direction of the first electrode 30 opposite to the color sub-pixel group 11 included in the second pixel unit 20 is the same as the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11.
It will be appreciated that the extending direction of the first electrode 31 opposite to the color sub-pixel group 11 included in the first pixel unit 10 is the same as the extending direction of the opening area of the sub-pixel included in the first sub-pixel group 12; the extending direction of the first electrode 30 opposite to the color sub-pixel group 11 included in the second pixel unit 20 is the same as the extending direction of the opening area of the sub-pixel included in the color sub-pixel group 11. In other words, the extending direction of the first electrode 30 corresponding to the color sub-pixel group 11 included in the first pixel unit 10 is different from the extending direction of the first electrode 30 corresponding to the color sub-pixel group 11 included in the second pixel unit 20.

In an alternative embodiment of the present invention, the first subpixel group 12 includes an acute angle between the extending direction of the opening area of the subpixel and the first direction x is not less than 70 degrees.
It will be appreciated that the first sub-pixel 12 includes sub-pixels having an acute angle of not less than 70 degrees in the angle between the extending direction of the opening region of the sub-pixel and the first direction x. Since the degree of the angle between the extending direction of the opening region of the sub-pixel included in the color pixel group 11 and the first direction x is the same as the degree of the angle between the extending direction of the opening region of the sub-pixel included in the first sub-pixel 12 and the first direction x, the acute angle between the extending direction of the opening region of the sub-pixel included in the color pixel group 11 and the first direction x is also not less than 70 degrees. Since the first pixel units 10 and the second pixels 20 are alternately arranged in order in the first direction x, the first pixel units 10 and the second pixel units 20 are repeatedly arranged in order in the second direction y. Accordingly, an excessively large gap between adjacent first and second pixel units 10 and 20 due to an excessively large offset of the color sub-pixel group 11, the first sub-pixel group 12, or the second sub-pixel group 13 should be avoided. Therefore, the acute angle of the included angle between the extending direction of the opening area of the sub-pixel included in the first sub-pixel 12 and the first direction x is not less than 70 degrees, so that the first pixel unit 10 or the second pixel unit 20 approaches to a rectangle, so as to improve the opening ratio of the display panel 100.
