Description

Technical Field

[0001] The present invention relates to the field of display technologies, and in particular, to a display panel and a display device. Background Art

[0002] As an important part of the information industry, display technology has played an important role in the development of information technology. Whether it is a large TV or a notebook, or a small mobile phone or tablet, it cannot do without the support of display technology. With the development of science and technology, display technology has also evolved from the initial cathode ray tube display technology (CRT) to flat panel display technology (FPD). Flat panel displays have further extended to plasma display (PDP), liquid crystal display (LCD), organic light-emitting diode display (OLED), micro light-emitting diode display and other technical routes.

[0003] In a display panel, the pixel arrangement directly affects the display performance of organic light-emitting displays. Therefore, how to arrange each sub-pixel in the display panel to make the display effect of the display panel better has become the research focus of relevant technical personnel. Summary of the Invention

[0004] The present invention provides a display panel and a display device, and designs the arrangement of sub-pixels in the display panel to improve the display effect.

[0005] In a first aspect, an embodiment of the present invention provides a display panel, including a plurality of pixel units arranged in rows and columns;

[0006] The pixel unit includes a first region, a second region, and a third region, and the first region, the second region, and the third region respectively include sub-pixels of different emission colors;

[0007] Along a first direction, the second region is located between the first region and the third region; the second region includes a first sub-region and a second sub-region, and along a second direction, the third region is located between the first sub-region and the second sub-region.

[0008] In a second aspect, an embodiment of the present invention provides a display device, including the display panel described in the first aspect.

[0009] An embodiment of the present invention provides a display panel. The third region, the second region, and the first region with different emission colors are arranged in sequence along the first direction, facilitating the formation of color display by mixing the light emitted by the third region, the second region, and the first region. The first region and the third region are separated by the second region, and the distance between the first region and the third region is relatively far. When the sub-pixels in the first region emit light, the sub-pixels in the third region will not have crosstalk; when the sub-pixels in the third region emit light, the sub-pixels in the first region will not have crosstalk, improving the problem of crosstalk of sub-pixels. The second region is split into a first sub-region and a second sub-region, and the width of the connection part between the first sub-region and the second sub-region is smaller than the width of the first sub-region except for the connection part, and the width of the connection part between the first sub-region and the second sub-region is smaller than the width of the second sub-region except for the connection part. The width of the connection part between the first sub-region and the second sub-region is small, and the first sub-region and the second sub-region are relatively independent, reducing the granularity of pixel arrangement. The first sub-region and the second sub-region are dispersed on both sides of the third region, and the regions of each emission color are arranged more evenly. By designing the arrangement mode of the sub-pixels in the display panel, the display effect is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0031] Figure 1 a schematic top view structural view of a display panel provided by an embodiment of the present invention, Figure 2 is Figure 1 a magnified structural view of the pixel unit in Figure 3 is Figure 2Schematic structural diagram of the first region in Figure 4 is Figure 2 Schematic structural diagram of the second region in Figure 5 is Figure 2 Schematic structural diagram of the third region in Figures 1 - 5 , the display panel includes a plurality of pixel units 10 arranged in rows and columns. The plurality of pixel units 10 are arranged in an array in a first direction and a second direction. The pixel unit 10 includes a first region 11, a second region 12, and a third region 13. The first region 11, the second region 12, and the third region 13 respectively include sub-pixels 20 of different emission colors. The emission color of the sub-pixels 20 in the first region 11 is different from the emission color of the sub-pixels 20 in the second region 12. The emission color of the sub-pixels 20 in the first region 11 is different from the emission color of the sub-pixels 20 in the third region 13. The emission color of the sub-pixels 20 in the second region 12 is different from the emission color of the sub-pixels 20 in the third region 13. In the embodiments of the present invention, the number of sub-pixels 20 in each region is not limited. The first region 11 may include one or more sub-pixels 20. The second region 12 may include one or more sub-pixels 20. The third region 13 may include one or more sub-pixels 20.

[0032] Along the first direction, the second region 12 is located between the first region 11 and the third region 13. The second region 12 includes a first sub-region 121 and a second sub-region 122. Along the second direction, the third region 13 is located between the first sub-region 121 and the second sub-region 122. Both the first sub-region 121 and the second sub-region 122 are located on the periphery of the third region 13, and the first sub-region 121 and the second sub-region 122 semi-surround the third region 13.

[0033] An embodiment of the present invention provides a display panel. Third region 13, second region 12, and first region 11 with different emission colors are arranged in sequence along a first direction, facilitating the formation of color display by mixing the light emitted by third region 13, second region 12, and first region 11. First region 11 and third region 13 are separated by second region 12, and the distance between first region 11 and third region 13 is relatively far. When the sub-pixels 20 in first region 11 emit light, the sub-pixels 20 in third region 13 will not have crosstalk. When the sub-pixels 20 in third region 13 emit light, the sub-pixels 20 in first region 11 will not have crosstalk, improving the problem of crosstalk of sub-pixels. Second region 12 is split into first sub-region 121 and second sub-region 122, and the width of the connection part between first sub-region 121 and second sub-region 122 is less than the width of first sub-region 121 except for the connection part, and the width of the connection part between first sub-region 121 and second sub-region 122 is less than the width of second sub-region 122 except for the connection part. The width of the connection part between first sub-region 121 and second sub-region 122 is small, and first sub-region 121 and second sub-region 122 are relatively independent, reducing the granularity of pixel arrangement. First sub-region 121 and second sub-region 122 are dispersed on both sides of third region 13, and the regions of each emission color are arranged more evenly. By designing the arrangement mode of the sub-pixels in the display panel, the display effect is improved.

[0034] Optionally, referring to Figure 2 and Figure 3 , pixel unit 10 includes first side 301, second side 302, and third side 303. Third side 303 is connected to first side 301, and third side 303 is connected to second side 302. First region 11 includes fourth side 304, fifth side 305, and sixth side 306. Sixth side 306 is connected to fourth side 304, and sixth side 306 is connected to fifth side 305. First side 301 overlaps with fourth side 304, and second side 302 overlaps with fifth side 305.

[0035] Exemplarily, referring to Figure 2 and Figure 3 , first region 11 is a corner region of pixel unit 10, and the sub-pixels 20 in first region 11 are arranged at a corner of pixel unit 10. Along the opposite direction of the first direction, that is, along the direction away from the corner of pixel unit 10, the width of first region 11 in the second direction is getting larger and larger.

[0036] Optionally, referring to Figure 2 and Figure 3, the third side 303 is parallel to the sixth side 306. In the direction perpendicular to the third side 303, the height of the pixel unit 10 is D1, and the height of the first region 11 is D2. It satisfies: D2 / D1 = 0.618. That is to say, the height of the first region 11 is set to 0.618 times the height of the pixel unit 10. In this way, the area ratio of the first region 11 in the pixel unit 10 is increased, and the light-emitting area of the sub-pixels 20 in the first region 11 is increased. On the other hand, 0.618 is the golden ratio point. In this way, the coordination of the first region 11 in the pixel unit 10 can be improved, the uniformity of color mixing of the sub-pixels 20 in the first region 11, the sub-pixels 20 in the second region 12, and the sub-pixels 20 in the third region 13 can be improved, and the display effect is enhanced.

[0037] Optionally, referring to Figure 2 and Figure 3 , any two of the first side 301, the second side 302, and the third side 303 are connected. The first side 301 is connected to the second side 302 and the third side 303. The second side 302 is connected to the first side 301 and the third side 303. The shape of the pixel unit 10 is a triangle. Any two of the fourth side 304, the fifth side 305, and the sixth side 306 are connected. The fourth side 304 is connected to the fifth side 305 and the sixth side 306. The fifth side 305 is connected to the fourth side 304 and the sixth side 306. The sixth side 306 is connected to the fourth side 304 and the fifth side 305. The shape of the first region 11 is a triangle.

[0038] Optionally, referring to Figure 2 and Figure 3 , the included angle between the third side 303 and the first side 301 is 60°, and the included angle between the third side 303 and the second side 302 is 60°. The included angle between the sixth side 306 and the fourth side 304 is 60°, and the included angle between the sixth side 306 and the fifth side 305 is 60°.

[0039] Exemplarily, referring to Figure 2 and Figure 3 , the included angle between the third side 303 and the first side 301 is 60°, the included angle between the third side 303 and the second side 302 is 60°, the included angle between the first side 301 and the second side 302 is 60°, and the shape of the pixel unit 10 is an equilateral triangle. Similarly, the included angle between the sixth side 306 and the fourth side 304 is 60°, the included angle between the sixth side 306 and the fifth side 305 is 60°, the included angle between the fourth side 304 and the fifth side 305 is 60°, and the shape of the first region 11 is an equilateral triangle. In other embodiments, the pixel unit 10 and the first region 11 may also be other shapes other than triangles.

[0040] Figure 6 This is a schematic top view structure diagram of another pixel unit provided by an embodiment of the present invention. Figure 7 For Figure 6Schematic structural diagram of the first region, refer to Figure 6 and Figure 7 , the included angle between the third side 303 and the first side 301 is 45°, and the included angle between the third side 303 and the second side 302 is 45°. The included angle between the sixth side 306 and the fourth side 304 is 45°, and the included angle between the sixth side 306 and the fifth side 305 is 45°. Combining with reference Figure 1 , the pixel units 10 are arranged in rows and columns in the first direction and the second direction, and the corners of the pixel units 10 at the outermost edges are 45°. At this time, the 45° corners are beneficial to reducing the jagged feeling during the display of the display panel.

[0041] Exemplarily, refer to Figure 2 and Figure 3 , the included angle between the third side 303 and the first side 301 is 45°, the included angle between the third side 303 and the second side 302 is 45°, and the included angle between the first side 301 and the second side 302 is 90°. The shape of the pixel unit 10 is an isosceles right triangle. Similarly, the included angle between the sixth side 306 and the fourth side 304 is 45°, the included angle between the sixth side 306 and the fifth side 305 is 45°, and the included angle between the fourth side 304 and the fifth side 305 is 90°. The shape of the first region 11 is an isosceles right triangle.

[0042] Exemplarily, refer to Figure 2 and Figure 3 , the length of the first side 301 is equal to the length of the second side 302, and the shape of the pixel unit 10 is an isosceles triangle. The length of the fourth side 304 is equal to the length of the fifth side 305, and the shape of the first region 11 is an isosceles triangle. The design of the isosceles triangle can increase the uniformity of the area distribution. For example, the left half and the right half of the first region 11 arranged in the second direction have the same light-emitting area, thereby improving the display uniformity.

[0043] Figure 8 Top view structural diagram of another display panel provided by an embodiment of the present invention, Figure 9 is Figure 8 an enlarged structural diagram of the pixel unit in Figure 10 is Figure 9 the structural diagram of the first region in Figures 8 - 10, the pixel unit 10 includes a seventh side 307, the seventh side 307 connects the first side 301 and the second side 302, the first side 301 connects the third side 303 and the seventh side 307, the third side 303 connects the first side 301 and the second side 302, and the second side 302 connects the third side 303 and the seventh side 307. The shape of the pixel unit 10 is a quadrilateral. The first region 11 includes an eighth side 308, the eighth side 308 connects the fourth side 304 and the fifth side 305, the fourth side 304 connects the sixth side 306 and the eighth side 308, the sixth side 306 connects the fourth side 304 and the fifth side 305, and the fifth side 305 connects the sixth side 306 and the eighth side 308. The shape of the first region 11 is a quadrilateral. The seventh side 307 overlaps with the eighth side 308.

[0044] Exemplarily, referring to Figures 8 - 10 , the seventh side 307 is parallel to the third side 303, and the shape of the pixel unit 10 is a trapezoid. Correspondingly, the eighth side 308 is parallel to the sixth side 306, and the shape of the first region 11 is a trapezoid. Combining with reference Figure 8 , the region jointly occupied by two trapezoid-shaped pixel units 10 is a parallelogram, that is, adjacent pixel units 10 can be closely arranged, and this pixel arrangement method has a high space utilization rate.

[0045] Exemplarily, referring to Figures 8 - 10 , the length of the first side 301 is equal to the length of the second side 302, and the shape of the pixel unit 10 is an isosceles trapezoid. The length of the fourth side 304 is equal to the length of the fifth side 305, and the shape of the first region 11 is an isosceles trapezoid. The design of the isosceles trapezoid can increase the uniformity of the region distribution. For example, the left and right halves of the first region 11 arranged along the second direction have the same light-emitting area, thereby improving the display uniformity.

[0046] Optionally, referring to Figures 2 - 5 , the pixel unit 10 includes a first side 301, a second side 302, and a third side 303. The second region 12 includes a tenth side 310, an eleventh side 311, a twelfth side 312, a thirteenth side 313, and a fourteenth side 314. The eleventh side 311 connects the tenth side 310 and the twelfth side 312, the thirteenth side 313 is connected to the tenth side 310, and the fourteenth side 314 is connected to the twelfth side 312. The tenth side 310 overlaps with the first side 301, and the second side 302 overlaps with the twelfth side 312. The eleventh side 311 overlaps with the sixth side 306. The third region 13 includes a fifteenth side 315, a sixteenth side 316, and a seventeenth side 317. The fifteenth side 315 overlaps with the thirteenth side 313, the sixteenth side 316 overlaps with the fourteenth side 314, and the seventeenth side 317 overlaps with the third side 303.

[0047] Exemplarily, referring to Figures 2 - 5, the third region 13 is a side region of the pixel unit 10, and the sub-pixels 20 in the third region 13 are arranged at one side of the pixel unit 10. Along the first direction, that is, along the direction away from this side of the pixel unit 10, the width of the third region 13 in the second direction becomes smaller and smaller. The shape of the second region 12 is adapted to the shape of the third region 13. The second region 12 forms an avoidance structure (i.e., a groove) at the middle position in the second direction for avoiding the second region 12 protruding towards the third region 13. Thus, the second region 12 forms a dumbbell-shaped structure with a smaller middle and larger ends, that is, a first sub-region 121 and a second sub-region 122 are formed.

[0048] Optionally, referring to Figures 2 - 5 , the third region 13 further includes an eighteenth side 318, and the eighteenth side 318 connects the fifteenth side 315 and the sixteenth side 316. The fifteenth side 315 connects the seventeenth side 317 and the eighteenth side 318. The seventeenth side 317 connects the fifteenth side 315 and the sixteenth side 316, and the sixteenth side 316 connects the seventeenth side 317 and the eighteenth side 318. The shape of the third region 13 is a quadrilateral.

[0049] Exemplarily, referring to Figures 2 - 5 , corresponding to the quadrilateral third region 13, the second region 12 includes a nineteenth side 319, and the nineteenth side 319 connects the thirteenth side 313 and the fourteenth side 314. The nineteenth side 319 overlaps with the eighteenth side 318.

[0050] Exemplarily, referring to Figures 2 - 5 , the seventeenth side 317 is parallel to the eighteenth side 318, and the shape of the third region 13 is a trapezoid. Further, the length of the fifteenth side 315 is equal to the length of the sixteenth side 316, and the shape of the third region 13 is an isosceles trapezoid. The design of the isosceles trapezoid can increase the uniformity of the region distribution. For example, the left half and the right half of the third region 13 arranged in the second direction have the same light-emitting area, thereby improving the display uniformity.

[0051] Exemplarily, referring to Figure 4 , the length of the tenth side 310 is equal to the length of the twelfth side 312, and the length of the thirteenth side 313 is equal to the length of the fourteenth side 314. The first sub-region 121 and the second sub-region 122 are symmetrically arranged, and the first sub-region 121 and the second sub-region 122 have the same light-emitting area, thereby improving the display uniformity.

[0052] Figure 11 This is a schematic top view structure diagram of another pixel unit provided by an embodiment of the present invention. Figure 12 is Figure 11 a schematic structure diagram of the second region in Figure 13 is Figure 11Schematic diagram of the structure of the third region, refer to Figures 11 - 13 , any two of the fifteenth side 315, the sixteenth side 136, and the seventeenth side 317 are connected. The fifteenth side 315 is connected to the sixteenth side 136 and the seventeenth side 317, the sixteenth side 136 is connected to the fifteenth side 315 and the seventeenth side 317. The seventeenth side 317 is connected to the fifteenth side 315 and the sixteenth side 136. The shape of the third region 13 is triangular.

[0053] Exemplarily, corresponding to the triangular third region 13, in the second region 12, the thirteenth side 313 is connected to the tenth side 310 and the fourteenth side 314, and the fourteenth side 314 is connected to the thirteenth side 313 and the twelfth side 312.

[0054] Optionally, refer to Figures 2 - 5 , the multiple sub-pixels 20 include a blue sub-pixel 21, a green sub-pixel 22, and a red sub-pixel 23. The blue sub-pixel 21 emits blue light, the green sub-pixel 22 emits green light, and the red sub-pixel 23 emits red light. The blue sub-pixel 21 is located in the first region 11, the green sub-pixel 22 is located in the second region 12, and the red sub-pixel 23 is located in the third region 13. The advantage of such an arrangement is that the green sub-pixel 22 is located in the first sub-region 121 and the second sub-region 122. The human eye is most sensitive to green light. In addition to its own color effect, the green sub-pixel 22 also plays a role in improving brightness. The green sub-pixels 22 are dispersed in the first sub-region 121 and the second sub-region 122, improving the uniformity of brightness.

[0055] Exemplarily, refer to Figure 2 , the blue sub-pixel 21 is located in the first region 11, and the height of the first region 11 is set to 0.618 times the height of the pixel unit 10. In this way, the area ratio of the first region 11 in the pixel unit 10 is increased, the light-emitting area of the blue sub-pixel 21 in the first region 11 is increased, so that the driving current provided for the blue sub-pixel 21 can be reduced to achieve sufficient blue light emission brightness, and the service life of the blue sub-pixel 21 is extended.

[0056] Exemplarily, refer to Figure 2 , the area of the blue sub-pixel 21 is larger than the area of the red sub-pixel 23, and the area of the red sub-pixel 23 is larger than the area of the green sub-pixel 22.

[0057] Figure 14 For the cross-sectional structure diagram along AA' in Figure 2 , combined with reference to Figures 2 - 5 , and Figure 14, the display panel includes a substrate 41 and a pixel defining layer 43. The pixel defining layer 43 is located on one side of the substrate 41, and the pixel defining layer 43 is provided with a plurality of openings 431. The sub-pixel 20 includes an anode 201 and a light-emitting functional layer 202. The anode 201 is located between the pixel defining layer 43 and the substrate 41, and the light-emitting functional layer 202 is located in the opening 431. The area where the opening 431 is located is the area where the sub-pixel 20 is located. That is, the position of the opening 431 defines the sub-pixel 20. The area in the pixel defining layer 43 where no opening 431 is provided is the area in the pixel unit 10 where no sub-pixel 20 is provided. In the embodiment of the present invention, the display panel is an organic light-emitting display panel. In other embodiments, the display panel may also be other forms of display panels.

[0058] Figure 15 is a schematic cross-sectional structure diagram along Figure 4 BB' in, with reference to Figures 2 - 5 , and Figure 15 , the second region 12 includes an opening 431, and the opening 431 overlaps both the first sub-region 121 and the second sub-region 122. In the embodiment of the present invention, the second region 12 includes a green sub-pixel 22. In a direction perpendicular to the substrate 41, the shape of the green sub-pixel 22 is similar to the shape of the second region 12, and each side of the green sub-pixel 22 is correspondingly parallel to each side of the second region 12.

[0059] Figure 16 is another schematic cross-sectional structure diagram of the second region provided by the embodiment of the present invention. With reference to Figures 2 - 5 , and Figure 16 , the second region 12 includes two openings 431, and the two openings 431 respectively overlap the first sub-region 121 and the second sub-region 122. One of the two openings 431 overlaps the first sub-region 121, and the other of the two openings 431 overlaps the second sub-region 122. In the embodiment of the present invention, the second region 12 includes two green sub-pixels 22, and one of the two green sub-pixels 22 is located in the first sub-region 121, and the other of the two green sub-pixels 22 is located in the second sub-region 122.

[0060] Optionally, with reference to Figures 2 - 5 , and Figures 15 - 16 , the second region 12 includes an anode 201, and the anode 201 overlaps both the first sub-region 121 and the second sub-region 122.

[0061] Exemplarily, with reference to Figure 16, the sub-pixel 20 further includes a cathode 203, and the light-emitting functional layer 202 is located between the anode 201 and the cathode 203. The anode 201 overlaps with the light-emitting functional layer 202 in the first sub-region 121 to inject holes into the light-emitting functional layer 202, and the cathode 203 injects electrons into the light-emitting functional layer 202. Electrons and holes recombine and emit light in the light-emitting functional layer 202 in the first sub-region 121. The same anode 201 also overlaps with the light-emitting functional layer 202 in the second sub-region 122 to inject holes into the light-emitting functional layer 202, and the cathode 203 injects electrons into the light-emitting functional layer 202. Electrons and holes recombine and emit light in the light-emitting functional layer 202 in the second sub-region 122.
