The backlight module 200 provides a light source for the display panel 100 to ensure the normal display of the display panel 100.
The display device 10 of the present application can effectively improve the compression resistance of the display device 10, and when the display device 10 is under the action of an external pressure, the display effect is not easily affected, the display device 10 of the present application can be applied to different display panels 100, for example, when the display panel 100 is a common liquid crystal display panel 100, the first substrate 110 can be a color filter substrate 111, the second substrate 120 can be an array substrate 121, and when the display panel 100 is a COA display panel 100, the first substrate 110 can be a glass substrate; the present application only exemplifies the display panel 100 as a general liquid crystal display panel 100.
In the liquid crystal display panel, a color film substrate and an array substrate are arranged in a vertically opposite box manner, liquid crystal and a plurality of spacers used for maintaining the box thickness of the display panel are filled between the color film substrate and the array substrate, and when the display panel is under the pressure, the spacers easily scratch an alignment film or a pixel electrode of a pixel area, so that abnormal display is caused, and the phenomenon of touch mura caused by liquid crystal flowing is influenced.
In order to reduce the influence of the above problems on the display device 10, the present application is directed to the display panel 100 in the display device 10, and the specific improvements are as follows:
FIG. 2 is a partial schematic view of a display panel according to a first embodiment of the present application, and FIG. 3 is a partial top view of the display panel according to the first embodiment of the present application; as shown in fig. 2 and fig. 3, the present application discloses a display panel 100, which includes a first substrate 110, a second substrate 120, and a spacer 130, wherein the first substrate 110 and the second substrate 120 are disposed in a pair, one end of the spacer 130 is fixed on the first substrate 110, and the other end abuts against the second substrate 120; the spacers 130 are plural, and the spacers 130 are distributed between the first substrate 110 and the second substrate 120; the display panel 100 further includes a plurality of stoppers 150, the plurality of stoppers 150 are disposed on the second substrate 120, the spacers 130 at least include first spacers 131 and second spacers 132, the display panel 100 is divided into a plurality of pixel regions 160 arranged in an array, the first spacers 131 and the second spacers 132 are respectively disposed between two adjacent pixel regions 160, the first spacers 131 are disposed on only one side close to the pixel regions 160, the second spacers 132 are disposed on only one side close to the pixel regions 160 and provided with second stoppers 152, and the first stoppers 151 and the second stoppers 152 are disposed on different sides.
In the present application, only one stopper 150 is disposed on each of the first spacer 131 and the second spacer 132, which is close to the respective adjacent pixel region 160, so as to greatly reduce the volume occupied by the stopper in the display panel 100, reduce the influence on the flow of the liquid crystal 140, and improve the display quality of the display panel 100; when the display panel 100 is pressed to slide the spacer 130, the sliding direction of the spacer is uncertain, and at this time, the stoppers 150 on different sides of two adjacent pixel regions 160 cooperate with each other from different directions to limit the moving direction of the first spacer 131 or the second spacer 132, so as to prevent the spacer 130 from moving toward the pixel region 160 to scratch the alignment film 180 or prevent the spacer 130 from moving toward the pixel electrode 170 of the pixel region 160, which may cause the pixel electrode 170 to break.
When the display panel 100 is under pressure, the spacer 130 is squeezed, and the spacer 130 deforms during the squeezing process, so that the spacer 130 releases stress to restore its shape and then slides relatively on the second substrate 120, and because the sliding direction of the spacer 130 is uncertain, the spacer 130 is likely to slide towards the pixel area 160, which may scratch the alignment film 180 of the pixel area 160, and affect the display effect; therefore, a first stopper 151 is disposed on one side of the first spacer 131 close to the pixel region 160, and a second stopper 152 is disposed on one side of the second spacer 132 close to the other pixel region 160, so that between the pixel regions 160 close to each of the first spacer 131 and the second spacer 132, when the first spacer 131 slides toward one of the pixel regions 160 in which the stopper 150 is not disposed, the first spacer 152 stops the movement of the second spacer 132, and the second spacer 132 is restricted from following the first spacer 131, and when the movement of the second spacer 132 is restricted, the other spacers 130 moving toward the pixel region 160 on this side are also restricted, so that even if there is no stopper 150 on the moving side of the first spacer 131, the movement side is restricted by the second spacer 132, and thus the spacers 130 can effectively prevent the spacers 130 from scratching the pixel region 160 on this side.
When the second spacer 132 slides towards another pixel region 160 without the stopper 150, the first spacer 131 is blocked by the first stopper 151, and when the movement of the first spacer 131 is limited, other spacers 130 moving towards the pixel region 160 on the side are also limited, so that even if the moving side of the second spacer 131 does not have the stopper 150, the first spacer 131 is limited and cannot move continuously, thereby effectively preventing the spacer 130 from scratching the alignment film 180 of the pixel region 160 on the side.
By arranging the first stopper 151 and the second stopper 152 on different sides of the pixel area 160 adjacent to each of the first spacer 131 and the second spacer 132, the volume of the display panel 100 occupied by the stopper 150 arranged on each spacer 130 is reduced, the blocking of the fluidity of the liquid crystal 140 in the display panel 100 is reduced, and the occurrence of touch mura is reduced, meanwhile, by utilizing the principle that if the first spacer 131 moves towards the pixel area 160 on the side where the first stopper 151 is not arranged, the direction of the movement of the first spacer 131 and the movement of the second spacer 132 towards the pixel area 160 on the side where the second stopper 152 is arranged are correspondingly limited, that is, when the second spacer 132 is blocked by the second spacer 152, the first spacer 131 is correspondingly limited to move, and vice versa. Even if the moving direction of the spacer 150 is uncertain, the first stopper 151 and the second stopper 152 cooperate with each other to prevent the spacer 130 from scratching the alignment film 180 of the pixel region 160 on either side of the spacer, thereby improving the display effect of the display panel 100, improving the product quality of the display panel 100, and further prolonging the service life of the display panel 100.

When the display panel 100 is pressed, the spacers 130 slide, and the direction in which the spacers 130 slide may not only face the pixel region 160, but also may slide toward the pixel electrode 170 in the display panel 100, and when the spacers 130 slide toward the pixel electrode 170, the pixel electrode 170 connected to the metal layer 157 at the via hole 134 may be scratched, so that the pixel electrode 170 at the via hole 134 is broken, and the display effect is affected; the third stopper 153 is disposed between the third spacer 133 and the pixel electrode 170, when the third spacer 133 is deformed by pressure, a trend of moving toward the pixel electrode 170 at the via hole 134 is generated when stress is released, and the third stopper 153 can effectively block the third spacer 153 from moving toward the pixel electrode 170, so as to prevent the spacer 130 from sliding onto the pixel electrode 170, which may cause the pixel electrode 170 to break, further improve the display effect of the display panel 100, and improve the quality of the display panel 100.
Under the cooperation of the first stop block 151, the second stop block 152 and the third stop block 153, the spacer 130 is prevented from damaging the pixel electrodes 170 in the pixel areas 160 or the via holes 134 from different directions, the first stop block 151, the second stop block 152 and the third stop block 153 are used as a stop block group 158 and are distributed among a plurality of pixel areas 160, the area for limiting the movement of a plurality of spacers 130 is increased, and the effect of limiting the movement of the plurality of spacers 130 is improved.

This can effectively prevent the spacers 130 in the non-display region 210 from sliding toward the pixel region 160 and scratching the alignment film 180 or the pixel electrode 170 at the via 134 of the pixel region 160.
