Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Just as the display boundary of the transparent display area of the existing display device mentioned in the background art has the problem of poor display effect, the transparent display area of the existing display device is generally square, and the display effect of the product and the use experience of customers are affected.
In view of the above, the present embodiment provides a display panel, fig. 1 is a schematic structural diagram of the display panel according to the embodiment of the present invention, fig. 2 is an enlarged schematic diagram of a region a in fig. 1, and fig. 3 is an enlarged diagram of a region B in fig. 2. Referring to fig. 1 to 3, the display panel includes:
a first display area 1 and a second display area 2 adjacent to the first display area 1, the density of the sub-pixels of the first display area 1 being greater than the density of the sub-pixels of the second display area 2; in the sub-pixel units with the same light-emitting color, when the same gray scale is displayed, the light-emitting brightness of the sub-pixels of the second display area 2 is larger than that of the sub-pixels of the first display area 1; the second display area 2 comprises an arcuate border 3, the arcuate border 3 comprising a plurality of steps 4, each step 4 comprising a first edge 41; the first edge 41 and the first display area 1 comprise a first transition pixel column 5, and when the same gray scale is displayed, the luminous brightness of the sub-pixels in the first transition pixel column 5 is equal to the luminous brightness of the sub-pixels with the same color in the first display area 1; the spacing between adjacent sub-pixels in the first transition pixel column 5 is larger than the spacing between adjacent sub-pixels in the first display area 1 along the extension direction of the first edge 41.
Wherein the first display area 1 and the second display area 2 are adjacent, or the first display area 1 surrounds the second display area 2; the first display area 1 is a main screen area of the display panel, the second display area 2 is an auxiliary screen area of the display panel, the auxiliary screen area is a transparent display area, and optical sensors such as cameras are arranged corresponding to the auxiliary screen area. The first display area 1 and the second display area 2 are each composed of a plurality of sub-pixels, and the sub-pixels may include red sub-pixels, green sub-pixels, blue sub-pixels, and the like. Since the luminance of the sub-pixels of the second display area 2 is greater than the luminance of the sub-pixels of the first display area 1 in the sub-pixels of the same color when displaying the same gray scale, a luminance difference easily occurs at the boundary between the second display area 2 and the first display area 1, resulting in bright edges, dark edges, and the like, which affect the display effect.
According to the display panel, the second display area comprises an arc boundary, so that the shape of the second display area is more attractive, the display attractiveness of the display panel is improved, and a first transition pixel row is arranged between the first edge of a step of the arc boundary and the first display area.
Referring to fig. 3, when there is a wide gap between the first display area 1 and the first edge 41, the first display area 1 and the first edge 41 are easily dark edges at the display gap at the time of display, and the first transition pixel column 5 may be formed by inserting partial sub-pixels in the gap between the first display area 1 and the first edge 41 to eliminate the dark edges.
Fig. 4 is a partial enlarged view of a further display panel provided in this embodiment, referring to fig. 4, when the gap between the first display area 1 and the first edge 41 is small, since the brightness of the sub-pixels of the first display area 1 is small, the brightness of the sub-pixels of the first edge 41 is large, and the brightness contrast is relatively obvious, so that bright edges are likely to appear at the boundary when the first display area 1 and the first edge 41 are displayed, and the first transition pixel column 5 may be formed by removing part of the sub-pixels in the sub-pixel columns of the first display area 1 adjacent to the first edge 41, so as to eliminate bright lines.
It should be noted that the shape of the second display area 2 may be any shape having the arc-shaped boundary 3, such as a U-shape, an oval shape, a circular shape, or a water drop shape, and the present embodiment is not limited specifically.
Optionally, with continued reference to fig. 3, the spacing between adjacent sub-pixels in the first transition pixel column 5 is equal to the spacing between adjacent sub-pixels in the second display area 2 along the extension direction X of the first edge 41.
By the arrangement, the first transition pixel column 5 and the second display region 2 can be manufactured by adopting the same mask plate while the first transition pixel column 5 can eliminate the bright edge or the dark edge between the first display region 1 and the first edge 41, so that the process difficulty is reduced.
Optionally, the first side 41 includes a first color sub-pixel 10, a second color sub-pixel 20, and a third color sub-pixel 30 arranged in sequence; the first transition pixel column 5 includes a plurality of first color sub-pixels 10, second color sub-pixels 20, and third color sub-pixels 30 arranged in order.
This arrangement ensures that no color shift occurs in the area where the first display area 1 and the first edge 41 meet after the first transition pixel row 5 is inserted, and has a good display effect.
Optionally, with continued reference to fig. 3, each step 4 includes a second edge 42, the second edge 42 intersecting the first edge 41; the first color sub-pixels 10 and the second color sub-pixels 20 are alternately arranged in the second side 42 of the step 4, and the first color sub-pixels 10 are closer to the first display area 1 than the second color sub-pixels 20; the first display area 1 includes a first boundary area adjacent to the second side 42, in which first boundary area first pixel brightness reducing areas 12 and first pixel brightness improving areas 11 arranged at intervals along the extending direction Y of the second side 42 are included; when the same gray scale is displayed, the luminance of the sub-pixel of the first pixel luminance reducing region 12 is smaller than the luminance of the sub-pixel of the same color in the first display region 1; when the same gray scale is displayed, the luminance of the sub-pixel of the first pixel luminance improving region 11 is greater than the luminance of the sub-pixel of the same color in the first display region 1.
By arranging the brightness reduction region and the brightness enhancement region to be arranged, the brightness transition region can be widened, the bright line of the first display region 1 and the second edge 42 during display is lightened, and the display effect of the display panel is enhanced.
Alternatively, referring to fig. 3, the first pixel brightness enhancement region 11 is adjacent to the second color sub-pixel 20 of the second side 42, the first pixel brightness enhancement region 11 including the third color sub-pixel 30; the first pixel brightness reducing region 12 includes a first sub-reducing region 121 and a second sub-reducing region 122, the first sub-reducing region 121 including the first color sub-pixel 10 and the third color sub-pixel 30, and the second sub-reducing region 122 including the second color sub-pixel 20 and the third color sub-pixel 30.
Specifically, the first pixel brightness reducing region 12 and the first pixel brightness enhancing region 11 in the first boundary region along the extending direction Y of the second edge 42 are arranged at intervals, which means that one first pixel brightness enhancing region 11 corresponds to one first pixel brightness reducing region 12, and specifically, two sides of the first pixel brightness enhancing region 11 are respectively provided with a first sub-reducing region 121 and a second sub-reducing region 122, or one side of the first pixel brightness enhancing region includes the first sub-reducing region 121 and the second sub-reducing region 122.
By setting the brightness of the part of the first color sub-pixel 10, the second color sub-pixel 20 and the third color sub-pixel 30 in the first boundary region adjacent to the second side 42 to be weakened, the brightness of the part of the third color sub-pixel 30 is improved, the brightness transition region can be widened, the bright line when the first display region 1 and the second side 42 are displayed is lightened, and the display effect of the display panel is improved.
Further, the number of the third color sub-pixels 30 included in the first and second sub-attenuation regions 121 and 122 and the number of the third color sub-pixels 30 included in the first pixel luminance-increasing region 11 may be set to be greater than the sum of the luminance values of the third color sub-pixels 30 in the first pixel luminance-increasing region 12, which are not reduced with the first and second color sub-pixels 10 and 20, and the third color sub-pixels 30, and the degree of the luminance reduction of the first, second, and third color sub-pixels 10, 20 is the same, e.g., the gray scale of the first, second, and third color sub-pixels 10, 20 in one pixel group is the same, so that the luminance increase value of the third color sub-pixels 30 in the first pixel luminance-increasing region 11 is equal to the sum of the luminance values of the third color sub-pixels 30 in the first pixel luminance-decreasing region 12, which are not reduced with the first and second color sub-pixels 10 and 20 forming the pixel group, so that color shift does not occur when displayed in the first boundary region after the luminance adjustment value. Illustratively, the first pixel brightness-reducing region 12 includes one first color sub-pixel 10, one second color sub-pixel 20, and two third color sub-pixels 30, the first pixel brightness-increasing region 11 includes one third color sub-pixel 30, the brightness of each of the first color sub-pixel 10, the second color sub-pixel 20, and the two third color sub-pixels 30 in the first pixel brightness-reducing region 12 is reduced to zero, and the brightness of the third color pixel 30 in the first pixel brightness-increasing region 11 is increased by an amount equal to the brightness of the original display of one third color sub-pixel 30 in the first pixel brightness-reducing region 12.
Alternatively, referring to fig. 3, the first sub-attenuation region 121 includes one first color sub-pixel 10 and one third color sub-pixel 30, and the second sub-attenuation region 122 includes one second color sub-pixel 20 and one third color sub-pixel 30; the first pixel brightness enhancement region 11 includes a third color sub-pixel 30; the brightness of the first color sub-pixel 10, the second color sub-pixel 20, and the third color sub-pixel 30 in the first pixel brightness-reducing region 12 are all zero; when the same gray scale is displayed, the luminance of the third color sub-pixel 30 of the first pixel luminance improving region 11 is equal to the luminance of the third color sub-pixel 30 in the second display region 2.
Thus, the areas of the first and second sub-dimming areas 121 and 122 and the first pixel brightness enhancing area 11 are small, and the first pixel brightness reducing area 12 and the first pixel brightness enhancing area 11 are alternately arranged in the first boundary area so that the boundary brightness is more uniform. And by setting the brightness of the third color sub-pixel 30 of the first pixel brightness enhancement region 11 to be equal to the brightness of the third color sub-pixel 30 in the second display region 2, the third color sub-pixel 30 in the first pixel brightness enhancement region 11 can be prepared by adopting the same process as the sub-screen sub-pixel, thereby reducing the process cost.
Fig. 3 illustrates only one case of the first sub-weakening area 121 and the second sub-weakening area 122 by way of example, and is not a limitation of the present invention. Fig. 5 is a further enlarged view of the region B of fig. 2, and referring to fig. 5, the first sub-attenuation region 121 may include the third color sub-pixel 30 in the first pixel unit 101, the second sub-attenuation region 122 may include the first color sub-pixel 10 and the second color sub-pixel 20 in the second pixel unit 102, and the third color sub-pixel 30 in the third pixel unit 103.
Alternatively, with continued reference to fig. 3, in the first display area 1, the first color sub-pixel 10, the third color sub-pixel 30, and the second color sub-pixel 20 are sequentially arranged along the extending direction X of the first side 41 to form a plurality of sub-pixel columns;
the geometric center of the third color sub-pixel 30 of one sub-pixel column is located between the geometric centers of the first color sub-pixel 10 and the second color sub-pixel 20 of the other sub-pixel column adjacent to the third color sub-pixel 30 in the adjacent two sub-pixel columns; the third color sub-pixel 30 of one of the adjacent sub-pixel columns and the first color sub-pixel 10 and the second color sub-pixel 20 of the adjacent sub-pixel column adjacent to the third color sub-pixel 30 form a first type pixel unit 91.
In the second display area 2, the first color sub-pixel 10, the second color sub-pixel 20, and the third color sub-pixel 30 are sequentially arranged along the extending direction X of the first side 41 to form a plurality of sub-pixel columns;
the geometric center of the second color sub-pixel 20 of one sub-pixel column is located between the geometric centers of the first color sub-pixel 10 and the third color sub-pixel 30 of the other sub-pixel column adjacent to the second color sub-pixel 20 in the adjacent two sub-pixel columns; the second color sub-pixel 20 of one of the adjacent sub-pixel columns and the first color sub-pixel 10 and the third color sub-pixel 30 of the adjacent sub-pixel column adjacent to the second color sub-pixel 20 form a second type pixel unit 92.
Specifically, the first color sub-pixel 10, the third color sub-pixel 30 and the second color sub-pixel 20 may be one of red sub-pixel, green sub-pixel and blue sub-pixel, respectively.
Optionally, with continued reference to fig. 3, the first sub-attenuation region 121 includes the first color sub-pixel 10 and the third color sub-pixel 30 in the first pixel unit 101 adjacent to the first color sub-pixel 10 of the second side 42, and the second sub-attenuation region 122 includes the second color sub-pixel 20 in the second pixel unit 102 adjacent to the second color sub-pixel 20 of the second side 42 and the third sub-pixel 30 of the third pixel unit 103 located on a side of the second pixel unit 102 away from the second side 42 along the extending direction X of the first side 41; the first pixel brightness enhancement region 11 includes the third color sub-pixels 30 of the second pixel unit 102.
In this way, the brightness reducing regions and the brightness improving regions in the first boundary region adjacent to the second edge 42 in the first display region 1 are alternately arranged along the extending direction of the second edge 42, so that the brightness transition region is widened, the bright edge is lightened, the width of the brightness transition region is ensured not to be too wide, and the influence on the image display quality is avoided.
Fig. 6 is a partial enlarged view of still another display panel provided in the present embodiment. Optionally, referring to fig. 1 and 6, the second display area 2 includes a first straight boundary 6, and the first straight boundary 6 is parallel to the first edge;
a second transition pixel column 7 is included between the first straight boundary 6 and the first display area 1;
when the same gray scale is displayed, the luminous brightness of the sub-pixels in the second transition pixel column 7 is equal to the luminous brightness of the sub-pixels with the same color in the first display area 1; the pitch between adjacent sub-pixels in the second transition pixel column 7 is equal to the pitch between adjacent sub-pixels in the second display area 2 along the extension direction of the first straight line boundary.
Specifically, the second transition pixel column 7 can be used as a brightness transition region between the first display region 1 and the second display region 2, so that the brightness transition between the second display region 2 and the first display region 1 is widened, bright edges and dark edges between the first display region 1 and the second display region 2 at the first linear boundary 6 can be eliminated, and the display effect of the display panel is improved.
When a wider gap is formed between the first display area 1 and the first linear boundary 6, the first display area 1 and the first linear boundary 6 are likely to have a dark edge at the display gap during display, and the second transition pixel column 7 may be formed by inserting a partial subpixel in the gap between the first display area 1 and the first linear boundary 6 to eliminate the dark edge.
In addition, when the gap between the first display 1 area and the first straight boundary 6 is smaller, since the brightness of the first display area 1 is smaller, the brightness of the first straight boundary 6 is larger, and the brightness contrast is more obvious, so that bright edges are easy to appear at the boundary when the first display area 1 and the first straight boundary 6 are displayed, and the second transition pixel column 7 can be formed by removing part of sub-pixels in the image column of the first display area 1 adjacent to the first straight boundary 6, so as to eliminate the bright edges.
Fig. 7 is a partial enlarged view of still another display panel provided in the present embodiment. Referring to fig. 1 and 7, the second display area 2 further includes a second straight boundary 8, and the second straight boundary 8 and the second side are parallel to each other; the first color sub-pixels 10 and the second color sub-pixels 20 are alternately arranged in the second straight boundary 8, and the first color sub-pixels 10 are closer to the first display area 1 than the second color sub-pixels 20;
the first display area 1 includes a second boundary area adjacent to the second straight boundary 8, and the second boundary area includes second pixel brightness reducing areas 13 and second pixel brightness improving areas 14 arranged at intervals along the extending direction of the second straight boundary; when the same gray scale is displayed, the brightness of the sub-pixels of the second pixel brightness reduction region 13 is smaller than the brightness of the sub-pixels of the same color in the first display region 1; when the same gray scale is displayed, the luminance of the sub-pixels of the second pixel luminance improving region 14 is greater than the luminance of the sub-pixels of the same color in the first display region 1. The arrangement can widen the brightness transition area, lighten the bright line when the first display area 1 and the second linear boundary 8 are displayed, and improve the display effect of the display panel.
Optionally, the second pixel brightness reducing area 13 includes a first color sub-pixel 10, a second color sub-pixel 20 and a third color sub-pixel 30, and the number of the third color sub-pixels 30 is greater than the number of the first color sub-pixels 10, and the number of the third color sub-pixels 30 is greater than the number of the second color sub-pixels 20; the second pixel brightness enhancement region 14 includes a third color sub-pixel 30. Specifically, by setting the brightness of the part of the first color sub-pixel 10, the second color sub-pixel 20, and the third color sub-pixel 30 in the second boundary region adjacent to the second straight boundary 8 to be weakened, the brightness of the part of the third color sub-pixel 30 is improved, the brightness transition region can be widened, the bright line when the first display region 1 and the second straight boundary 8 are displayed is lightened, and the display effect of the display panel is improved.
Illustratively, the second pixel brightness reducing region 13 may include a first color sub-pixel 10 and a second color sub-pixel 20 of the fourth pixel unit 104 adjacent to the first color sub-pixel 10 of the second straight boundary 8, a second color sub-pixel 20 of the fifth pixel unit 105 adjacent to the second color sub-pixel 20 of the second straight boundary 8, and a third sub-pixel 30 of the sixth pixel unit 106 located on a side of the fifth pixel unit 105 away from the second straight boundary 8 along the extending direction X of the first side 41; the first pixel brightness enhancement region 11 includes the third color sub-pixels 30 of the fifth pixel unit 105. The luminance of the sub-pixels in the second pixel luminance reducing region 13 may be zero and the luminance of the third color sub-pixel 30 in the second pixel luminance increasing region 14 is equal to the luminance of the same color sub-pixel in the second display region 2.
