Display panel with secured mechanical reliability
View Patent ↗A display panel with secured mechanical reliability comprises: a first plate including a display region and a non display region, a second plate facing the first plate, a first frit portion interposed between the first plate and the second plate and sealing the display region from outside, and a second frit portion separated from the first fit portion and comprising a plurality of sub-frits isolated from each other. The sub-frits are located between a first line which passes through points closest to edges of the first plate among outer points of the first frit portion with respect to a sealed space and extends parallel to the edges of the first plate and a second line which passes through points furthest from the edges of the first plate among inner points of the first frit portion with respect to the sealed space and extends parallel to the edges of the first plate.
1. A display panel, comprising:
a first plate including a display region having light emitters and a non-display region;
a second plate facing the first plate;
a first frit portion interposed between the first plate and the second plate and sealing the display region from the outside; and
a second frit portion separated from the first frit portion and including a plurality of sub-frits isolated from each other;
the sub-frits located between a first line which passes through points closest to edges of the first plate among outer points of the first frit portion with respect to a sealed space and extends parallel to the edges of the first plate, and a second line which passes through points farthest from the edges of the first plate among inner points of the first frit portion with respect to the sealed space and extends parallel to the edges of the first plate.
2. The display panel of claim 1 , wherein the sub-frits comprise first sub-frits located outside the first frit portion with respect to the sealed space and second sub-frits located inside the first frit portion with respect to the sealed space.
3. The display panel of claim 2 , wherein the first frit portion comprises horizontal frit portions parallel to the first line and vertical frit portions perpendicular to the first line, extends parallel to the edges of the first plate, and is in a shape of a loop having a zigzag pattern formed by the vertical frit portions and the horizontal frit portions alternately connected at right angles.
4. The display panel of claim 3 , wherein each of the sub-frits is located in a space formed by two vertical frit portions and a horizontal frit portion which connects the two vertical frit portions.
5. The display panel of claim 2 , wherein the first frit portion extends parallel to the edges of the first plate and is in the shape of a loop having a zigzag pattern which is at an acute angle to the first line and the second line.
6. The display panel of claim 5 , wherein the first sub-frits are located between ridges of the first frit portion which protrude outward with respect to the sealed space, and the second sub-frits are located between valleys of the first frit portion which are recessed inward with respect to the sealed space.
7. The display panel of claim 1 , wherein the sub-frits are surrounded by the first frit portion.
8. The display panel of claim 1 , wherein the first frit portion comprises a plurality of sealing frits.
9. The display panel of claim 8 , wherein the sub-frits are surrounded by the sealing frits.
10. The display panel of claim 9 , further comprising a plurality of sub-frits between the sealing frits.
11. The display panel of claim 8 , wherein the sub-frits are interposed between the sealing frits.
12. A display panel, comprising:
a first plate including a display region having light emitters and a non-display region;
a second plate facing the first plate;
a first frit portion interposed between the first plate and the second plate, and sealing the display region from the outside; and
a second frit portion separated from the first frit portion and comprising a plurality of sub-frits isolated from each other;
the sub-frits comprising first sub-frits located outside the first frit portion with respect to a sealed space and second sub-frits located inside the first frit portion with respect to the sealed space, and a width of the first frit portion in a direction perpendicular to the edges of the first plate being 0.25 to 0.75 times a width of a region formed by a first line which passes through points closest to the edges of the first plate among outer points of the first sub-frits with respect to the sealed space and which extends parallel to the edges of the first plate and a second line which passes through points farthest from the edges of the first plate among inner points of the second sub-frits with respect to the sealed space and extends parallel to the edges of the first plate.
13. The display panel of claim 12 , wherein the first frit portion has a linear pattern parallel to the edges of the first plate.
14. A display panel, comprising:
a first plate including a display region having light emitters and a non-display region;
a second plate facing the first plate; and
a frit interposed between the first plate and the second plate and sealing the display region from the outside;
the frit comprising horizontal frit portions parallel to edges of the first plate and vertical frit portions perpendicular to the edges of the first plate, extending parallel to the edges of the first plate, and being in a shape of a loop having a zigzag pattern formed by the vertical frit portions and the horizontal frit portions alternately connected at right angles.
15. The display panel of claim 14 , wherein an area of the frit is in a range of 0.9 to 0.95 times an area of a region surrounded by a first line which passes through outer edges of the horizontal frit portions on an outermost side of the frit with respect to a sealed space, and a second line which passes through inner edges of the horizontal frit portions on an innermost side of the frit with respect to the sealed space.
16. A display panel, comprising:
a first plate including a display region having light emitters and a non-display region;
a second plate facing the first plate;
a third frit portion interposed between the first plate and the second plate and sealing the display region from the outside; and
a fourth frit portion located adjacent to the third frit portion and extending along a circumference of the fourth frit portion;
each of the third frit portion and the fourth frit portion comprising horizontal frit portions which are parallel to edges of the first plate, and vertical frit portions which are perpendicular to the edges of the first plate and protrude from the horizontal frit portions, and each vertical frit portion of any one of the third frit portion and the fourth frit portion inserted into a region surrounded by a horizontal frit portion and two vertical frit portions of another one of the third and fourth frit portions.
