Fig. 1 is a schematic diagram of a tiled display device in the related art.
Referring to fig. 1, the applicant has found that when manufacturing a folded display screen or a tiled display screen, two identical display devices are generally manufactured for convenience of manufacturing, and the two display devices are symmetrically arranged about a connection point, so that signal lines of the display devices are conveniently arranged to be led out from a position far from the connection point. The pixels in each display device are arranged in an array, but the sub-pixels of different colors in the pixels are typically arranged in sequence along a row direction or a column direction. Because the two display devices are symmetrically arranged about the connection position, the sub-pixels in the two display devices can be arranged in reverse order, for example, the arrangement order of the sub-pixels of one display device is red-green-blue, and the arrangement order of the sub-pixels of the other display device is blue-green-red after the two display devices are symmetrically arranged. At this time, since the arrangement order of the sub-pixels is reversed, a problem of pixel misalignment occurs at the junction of the two display devices, thereby causing a deterioration of the display effect at the junction.
In view of the above analysis, the applicant proposes a display panel comprising a first sub-panel and a second sub-panel connected to each other, the first sub-panel and the second sub-panel being symmetrically arranged, the first pixel arrangement of the first sub-panel and the second pixel arrangement of the second sub-panel being also symmetrical. The first pixel arrangement structure and the second pixel arrangement structure comprise a plurality of repeating units, each repeating unit comprises at least one pixel group, and each pixel group comprises a first sub-pixel, a second sub-pixel and a third sub-pixel with different colors so as to realize display luminescence of the display panel. The repeated units are in central symmetry, so that the first sub-pixel, the second sub-pixel and the third sub-pixel in the repeated units of the first sub-panel and the second sub-panel are arranged in the same mode, the display effect at the joint of the first sub-panel and the second sub-panel is consistent, and the overall display effect of the display panel of the embodiment of the application is improved.
Fig. 2 is a schematic diagram of a display panel according to an embodiment of the application.
Referring to fig. 2, an embodiment of the present application provides a display panel, including: the first sub-panel 11 and the second sub-panel 21 connected to each other, the first sub-panel 11 and the second sub-panel 21 being symmetrically disposed about the first reference plane a; the first sub-panel 11 comprises a first pixel arrangement 111 and the second sub-panel 21 comprises a second pixel arrangement 211, the first pixel arrangement 111 and the second pixel arrangement 211 being symmetrical with respect to a first reference plane a; the first pixel arrangement structure 111 and the second pixel arrangement structure 211 each include a plurality of repeating units 31 arranged in an array, the repeating units 31 include at least one pixel group 32, the pixel group 32 includes a first sub-pixel 321, a second sub-pixel 322 and a third sub-pixel 323 with different colors, and the repeating units 31 are in a central symmetry structure.
The display panel is formed by connecting a first sub-panel 11 and a second sub-panel 21, and the first sub-panel 11 and the second sub-panel 21 have the same structure so as to facilitate processing and manufacturing. The first sub-panel 11 and the second sub-panel 21 are symmetrical with respect to the first reference plane a, that is, the junction of the first sub-panel 11 and the second sub-panel 21 is located at the first reference plane a. In consideration of the same structure of the first sub-panel 11 and the second sub-panel 21, since the first sub-panel 11 and the second sub-panel 21 are symmetrical with respect to the first reference plane a, the signal lines of the first sub-panel 11 are connected to the outside from the end far from the second sub-panel 21, and similarly the signal lines of the second sub-panel 21 are connected to the outside from the end far from the first sub-panel 11.
Considering that the first and second sub-panels 11 and 21 are symmetrically disposed about the first reference plane a, the first pixel arrangement 111 of the first sub-panel 11 and the second pixel arrangement 211 of the second sub-panel 21 are symmetrical about the first reference plane a. The first pixel arrangement structure 111 and the second pixel arrangement structure 211 each include a plurality of repeating units 31 arranged in an array, the repeating units 31 include at least one pixel group 32, and the pixel group 32 includes a first sub-pixel 321, a second sub-pixel 322, and a third sub-pixel 323 with different colors. The first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 of different colors cooperatively emit light, so that the pixel group 32 can display a color in which light of corresponding colors of the first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 are mixed. At least one pixel group 32 forms a repeating unit 31 and is arrayed within the first pixel arrangement 111 and the second pixel arrangement 211 with reference to the repeating unit 31. The first pixel arrangement 111 corresponds to the arrangement of all the pixel groups 32 in the first sub-panel 11, and the second pixel arrangement 211 corresponds to the arrangement of all the pixel groups 32 in the second sub-panel 21.
In addition, the colors of the first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 are different, and by controlling the first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 to emit light with different intensities and mix, the pixel group 32 can exhibit a certain color. Illustratively, the first sub-pixel 321 may be a green sub-pixel, the second sub-pixel 322 may be a red sub-pixel, and the third sub-pixel 323 may be a blue sub-pixel.
The repeating unit 31 is in a central symmetry structure, so that the arrangement of the first sub-pixel 321, the second sub-pixel 322 and the third sub-pixel 323 in each pixel group 32 is in central symmetry. Since the first pixel arrangement structure 111 and the second pixel arrangement structure 211 are symmetrical with respect to the first reference plane a, the first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 on the first sub-panel 11 are arranged in the same manner as the first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 of the second sub-panel 21 in the row direction and the column direction. That is, at the connection of the first sub-panel 11 and the second sub-panel 21, the first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 on the first sub-panel 11 are arranged in the same manner as the first sub-pixel 321, the second sub-pixel 322, and the third sub-pixel 323 of the second sub-panel 21 in the row direction and the column direction. Therefore, at the connection position of the first sub-panel 11 and the second sub-panel 21, the display effect of the first sub-panel 11 and the second sub-panel 21 is consistent, so that the display effect of the display panel of the embodiment of the application at the connection position of the first sub-panel 11 and the second sub-panel 21 is improved.
