Display panel and display device
View Patent ↗The present invention provides a display panel and a display device. Within a bezel region, the display panel includes a first substrate and a second substrate arranged corresponding to each other. A protrusion is placed on a first surface of the first substrate, which faces the second substrate. The display panel also includes a sealing adhesive filled in a gap between the first substrate and the second substrate. Because of the protrusion, a contact area between the first substrate and the sealing adhesive is increased, a longer path for entry of moisture is created, and the display panel, such as a liquid crystal display, has a better waterproofing.
1. A display panel, wherein within a bezel region of the display panel, the display panel comprises:
a first substrate and a second substrate arranged corresponding to each other, the first substrate comprising a surface, a protrusion disposed on the surface of the first substrate, the second substrate comprises a surface, the surface of the first substrate facing the surface of the second substrate, wherein a recess is defined in the surface of the second substrate and faces the first substrate, the protrusion is disposed corresponding to the recess, the first substrate is separated from the second substrate by a distance, a thickness of the protrusion is greater than the distance, the protrusion is made of a light shielding material, and an entire length of each of at least one side surface of the protrusion is distributed with sawtooth shaped portions; and
a sealing adhesive filled in a gap between the first substrate and the second substrate, the sealing adhesive contacting the protrusion.
2. The display panel according to claim 1 , wherein the display panel comprises two recesses.
3. The display panel according to claim 1 , wherein the display panel comprises two protrusions.
4. The display panel according to claim 3 , wherein the protrusions have a same thickness.
5. The display panel according to claim 1 , wherein a cross-section of the protrusion is trapezoid in shape.
6. A display device, the display device comprising a display panel and a backlight source, wherein within a bezel region of the display panel, the display panel comprises:
a first substrate and a second substrate arranged corresponding to each other, the first substrate comprising a surface. a protrusion disposed on the surface of the first substrate, the second substrate comprises a surface, the surface of the first substrate facing the surface of the second substrate, wherein a recess is defined in the surface of the second substrate and faces the first substrate, the protrusion is disposed corresponding to the recess, the first substrate is separated from the second substrate by a distance, a thickness of the protrusion is greater than the distance. the protrusion is made of a light shielding material, and an entire length of each of at least one side surface of the protrusion is distributed with sawtooth shaped portions; and
a sealing adhesive filled in a gap between the first substrate and the second substrate, the sealing adhesive contacting the protrusion.
7. The display device according to claim 6 , wherein the display-device comprises two recesses.
8. The display device according to claim 6 , wherein the display device comprises two protrusions.
9. The display device according to claim 8 , wherein the protrusions have a same thickness.
10. The display device according to claim 6 , wherein a cross-section of the protrusion is trapezoid in shape.
