The embodiment of the application provides a spliced screen and a mobile terminal. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a splicing screen according to an embodiment of the present application. Fig. 2 is a schematic view of a first structure of a display panel according to an embodiment of the present disclosure. As shown in fig. 1 and fig. 2, a tiled display 100 provided in the embodiment of the present application includes a plurality of display panels 101. A patchwork 102 is arranged between two adjacent display panels 101. The display panel 101 has a first pixel unit 1011 disposed therein. The second pixel unit 1021 is arranged at the seam 102. The absolute value of the difference between the length L1 of the first pixel unit 1011 and the length L2 of the second pixel unit 1021 at the edge of the display panel 101 is less than or equal to 200 micrometers. The absolute value of the difference between the width D1 of the first pixel unit 1011 and the width D2 of the second pixel unit 1021 at the edge of the display panel 101 is less than or equal to 200 micrometers.
The first pixel unit 1011 is a liquid crystal pixel unit. The second pixel unit 1021 is an led pixel unit.
In the prior art, when a plurality of display panels are spliced into a spliced screen, a spliced seam exists between adjacent display panels. The display effect of the spliced screen is affected by the seam, and the display effect of the spliced screen is not affected by the seam. A plurality of leds are typically provided at the seams. However, the resolution of the display screen formed by the light emitting diodes is too low, the resolution of the display screen is not well matched with the resolution of the display panel, and the display effect of the spliced screen is still affected by the splicing seam. Specifically, when the display panel is transited to the display panel adjacent to the display panel through the seam, the display screen of the tiled screen may be greatly changed at the seam, thereby affecting the display effect of the tiled screen.
Note that the absolute value of the difference between the length L1 of the first pixel unit 1011 and the length L2 of the second pixel unit 1021 at the edge of the display panel 101 is less than or equal to 200 micrometers. The absolute value of the difference between the width D1 of the first pixel unit 1011 and the width D2 of the second pixel unit 1021 at the edge of the display panel 101 is less than or equal to 200 micrometers. When the display panel 101 is transited to the display panel 101 adjacent to the display panel through the seam 102, the length and the width of the pixel unit for displaying the picture are not changed suddenly, so that the display picture of the tiled screen 100 is basically not changed at the seam 102, and the display effect of the tiled screen 100 is further improved.
In the present embodiment, in the same display panel 101, the length L1 and the width D1 of the first pixel unit 1011 gradually increase along the direction from the center of the display panel 101 to the edge of the display panel 101.
In the prior art, the length and the width of the light emitting diode pixel unit are large. Because the resolution of the display panel that forms the tiled display is high, the length and width of the pixel elements of the display panel are small.
It should be noted that, when the difference between the length L1 of the first pixel unit 1011 at the edge of the display panel 101 and the length L2 of the second pixel unit 1021 is not large, the difference between the length L1 of the first pixel unit 1011 at the edge of the display panel 101 and the length L1 of the first pixel unit 1011 at the center of the display panel 101 is large, so that the length L1 of the first pixel unit 1011 appears a sudden change, and the display uniformity of the display panel 101 is affected.
It should be noted that, when the difference between the width D1 of the first pixel unit 1011 at the edge of the display panel 101 and the width D2 of the second pixel unit 1021 is not large, the difference between the width D1 of the first pixel unit 1011 at the edge of the display panel 101 and the width D1 of the first pixel unit 1011 at the center of the display panel 101 is large, so that the width D1 of the first pixel unit 1011 appears a sudden change, and the display uniformity of the display panel 101 is affected.
When the length L1 and the width D1 of the first pixel unit 1011 both increase gradually along the direction from the center of the display panel 101 to the edge of the display panel 101, the length L1 and the width D1 of the adjacent first pixel unit 1011 both do not differ much, and there is no abrupt change in the length L1 and the width D1 of the first pixel unit 1011. Therefore, by gradually increasing the length L1 and the width D1 of the first pixel unit 1011 in the direction from the center of the display panel 101 to the edge of the display panel 101, not only the problem of poor display effect of the tiled display 100 at the seam 102 can be solved, but also the display uniformity of the display panel 101 is not affected.
The length L2 of the second pixel unit 1021 is 1185 microns to 1215 microns. The width D2 of the second pixel element 1021 is 1185 microns to 1215 microns. Specifically, the length L2 of the second pixel unit 1021 is 1185 microns, 1188 microns, 1191 microns, 1195 microns, 1200 microns, 1205 microns, or 1215 microns. The width D2 of the second pixel unit 1021 is 1185 microns, 1188 microns, 1191 microns, 1195 microns, 1200 microns, 1205 microns, or 1215 microns. The specific values of the length L2 and the width D2 of the second pixel unit 1021 are determined by the process requirements of the tiled display 100.
Referring to fig. 3, fig. 3 is a second structural schematic diagram of a display panel according to an embodiment of the present disclosure. As shown in fig. 3, a display panel 201 provided in an embodiment of the present application is different from the display panel 101 provided in the above embodiment in that: the first pixel unit 1011 includes a plurality of central pixel units 1011a and a plurality of edge pixel units 1011 b. The edge pixel unit 1011b is disposed around the center pixel unit 1011 a. The absolute value of the difference between the length L3 of the edge pixel element 1011b and the length L2 of the second pixel element 1021 is less than 200 microns, and the length of the edge pixel element 1011b is greater than the length L4 of the center pixel element 1011 a. The absolute value of the difference between the width D3 of the edge pixel unit 1011b and the width D2 of the second pixel unit 1021 is less than 200 microns, and the length of the edge pixel unit 1011b is greater than the width D4 of the center pixel unit 1011 a. The length L4 and the width D4 of the center pixel element 1011a are equal.
The central pixel unit 1011a is located at the center of the display panel 101, and covers most of the display panel 101. The edge pixel unit 1011b is located at the edge of the display panel 101, and covers a small portion of the display panel 101. The length L4 and the width D4 of the center pixel unit 1011a are small, and the length L3 and the width D3 of the edge pixel unit 1011b are large.
It should be noted that the length and the width of the pixel unit of the display panel 101 may affect the resolution of the display panel 101. The smaller the size of the pixel unit of the display panel 101, the greater the resolution of the display panel 101. By providing the center pixel unit 1011a having a small length L4 and a small width D4 in most of the area of the display panel 101, the resolution of the display panel 101 can be improved.
It should be noted that the edge pixel unit 1011b is disposed in the edge region of the display panel 101, and the length L3 of the edge pixel unit 1011b and the length L2 of the pixel unit 1021 are not much different, and the width D3 of the edge pixel unit 1011b and the width D2 of the pixel unit 1021 are not much different, so that the problem that the display effect of the tiled display 100 at the seam 102 is not good can be solved. In addition, the edge pixel unit 1011b only covers a small area of the display panel 101, and does not affect the resolution of the display panel 101.

As shown in fig. 4, a display panel 301 provided in an embodiment of the present application is different from the display panel 201 provided in the above embodiment in that: the length L4 and the width D4 of the central pixel unit 1011a are gradually increased along the direction from the center of the display panel 101 to the edge of the display panel.
It should be noted that the difference between the length L3 of the edge pixel unit 1011b and the length L4 of the center pixel unit 1011a is large, and the difference between the width D3 of the edge pixel unit 1011b and the width D4 of the center pixel unit 1011a is large, so that the phenomenon of sudden size change occurs at the boundary between the edge pixel unit 1011b and the center pixel unit 1011a, and the display uniformity of the display panel 101 is affected.
When the length L4 and the width D4 of the central pixel unit 1011a both increase gradually along the direction from the center of the display panel 101 to the edge of the display panel 101, the phenomenon of abrupt size change does not occur at the boundary between the edge pixel unit 1011b and the central pixel unit 1011 a. In addition, the length L4 and the width D4 of the central pixel unit 1011a gradually increase, and the adjacent central pixel unit 1011a does not have a sudden change in size. Therefore, by gradually increasing the length L4 and the width D4 of the central pixel unit 1011a in the direction from the center of the display panel 101 to the edge of the display panel 101, not only the problem of poor display effect of the tiled screen 100 at the seam 102 can be solved, but also the display uniformity of the display panel 101 is not affected.
