Display panel, display module and display device
View Patent ↗The present application provides a display panel, a display module and a display device. In a non-display region of the display panel, exhaust holes are disposed inside arranging areas of alignment terminals. When attaching a support film in the non-display region, the exhaust holes serve as gas discharge channels to exhaust the gas located in the arranging areas of the alignment terminals and located between the support film and the display panel, thereby alleviating the problem of bubbles between the display panel and the support film in existing flexible displays.
1. A display panel, wherein in a non-display region, the display panel comprises:
alignment terminals; and
exhaust holes, formed inside arranging areas of the alignment terminals and penetrating the display panel, configured to exhaust bubbles generated when attaching the display panel to a support film.
2. The display panel according to claim 1 , wherein the exhaust holes are disposed in locations where the alignment terminals are located.
3. The display panel according to claim 2 , wherein only one exhaust hole is disposed in a location where one alignment terminal is located.
4. The display panel according to claim 3 , wherein the exhaust hole is located at a center of the alignment terminal.
5. The display panel according to claim 2 , wherein at least two exhaust holes are disposed in a location where one alignment terminal is located.
6. The display panel according to claim 5 , wherein the exhaust holes are distributed uniformly in the location where the alignment terminal is located.
7. The display panel according to claim 5 , wherein the exhaust holes are same in size and shape.
8. The display panel according to claim 5 , wherein at least one of the exhaust holes is different from other exhaust holes in size, or at least one of the exhaust holes is different from other exhaust holes in shape.
9. The display panel according to claim 2 , wherein an area of the exhaust hole occupies 30% to 60% of an area of the alignment terminal.
10. The display panel according to claim 1 , wherein the exhaust hole is shaped as one or more of a circle, a quadrilateral and a cross.
11. A display module, comprising:
a display panel comprising alignment terminals and first exhaust holes in a non-display region, the first exhaust holes formed inside arranging areas of the alignment terminals and penetrating the display panel, the first exhaust holes configured to exhaust bubbles generated when attaching the display panel to a support film; and
the support film, configured to support the display panel, comprising a first support film located in a display region and a second support film located in the non-display region.
12. The display module according to claim 11 , wherein a plurality of second exhaust holes are disposed on the second support film, and the second exhaust holes are configured to exhaust bubbles generated when attaching the display panel to the second support film.
13. The display module according to claim 12 , wherein a density of the second exhaust holes corresponding to the arranging areas of the alignment terminals is greater than a density of the second exhaust holes corresponding to other areas.
14. The display module according to claim 12 , wherein the second exhaust holes are distributed uniformly over the second support film.
15. The display module according to claim 12 , wherein the second exhaust holes are same in size and shape.
16. The display module according to claim 15 , wherein the second exhaust holes and the first exhaust holes have a same shape, and the second exhaust holes and the first exhaust holes have a same size.
17. The display module according to claim 15 , wherein the second exhaust holes and the first exhaust holes have different shapes, or the second exhaust holes and the first exhaust holes have different sizes.
18. The display module according to claim 11 , wherein at least one of the second exhaust holes is different from other second exhaust holes in size, or at least one of the second exhaust holes is different from other second exhaust holes in shape.
19. The display module according to claim 11 , wherein the second exhaust holes are shaped as one or more of a circle, a quadrilateral and a cross.
20. A display device, comprising a display module, the display module comprising:
a display panel, comprising alignment terminals and first exhaust holes in a non-display region, the first exhaust holes formed inside arranging areas of the alignment terminals and penetrating the display panel, the first exhaust holes configured to exhaust bubbles generated when attaching the display panel to a support film; and
the support film, configured to support the display panel, comprising a first support film located in a display region and a second support film located in the non-display region.
