Organic light emitting diode display
View Patent ↗An OLED display is disclosed. The display includes a rear substrate, a front substrate facing the rear substrate, a cell seal provided between the rear and front substrates to adhere the two substrates to each other, and a reinforcement member provided between the rear and front substrates adjacent to the cell seal to adhere the two substrates to each other.
1. An organic light emitting diode (OLED) display, comprising:
a rear substrate including an OLED and a driving circuit unit;
a front substrate facing the rear substrate;
a cell seal provided between the rear substrate and the front substrate and adhering the rear substrate and the front substrate to each other; and
a reinforcement member provided between the rear substrate and the front substrate, the reinforcement member contacting the cell seal and adhering the rear substrate and the front substrate to each other, wherein the front substrate includes a first inducing portion configured to induce flow of the reinforcement member towards the cell seal and wherein the rear substrate includes a second inducing portion configured to induce flow of the reinforcement member towards the cell seal; and
one or more additional inducing portions formed in one or more layers between the front and rear substrates.
2. The OLED display of claim 1 , wherein the first inducing portion comprises a triangular space between a sloped surface of the front substrate and the rear substrate.
3. The OLED display of claim 1 , wherein the first inducing portion comprises a substantially rectangular cavity.
4. The OLED display of claim 1 , wherein the first inducing portion has a cross-sectional area defined by a portion of a circle.
5. The OLED display of claim 1 , wherein the first inducing portion has a cross-sectional area defined by a portion of an ellipse.
6. The OLED display of claim 1 , wherein the reinforcement member comprises:
a reinforcing portion between two substantially parallel portions of the front and rear substrates; and
a reinforcing portion in the first inducing portion.
7. The OLED display of claim 1 , wherein the cell seal is formed of a glass frit, and the reinforcement member is formed of a resin.
8. The OLED display of claim 1 , wherein the reinforcement member comprises:
a reinforcing portion between two substantially parallel portions of the front and rear substrates; and
a reinforcing portion between a groove in one of the front and rear substrates and the other of the front and rear substrates.
9. An array of displays, the array comprising:
front and rear substrates;
adjacent cell seals formed at peripheral portions of adjacent displays, the cell seals formed between the front and rear substrates, wherein the cell seals adhere the rear substrate and the front substrate to each other, and wherein the cell seals are spaced apart from one another, forming a cavity defined by the cell seals, the front substrate and the rear substrate; and
a reinforcement member formed in the cavity, wherein the reinforcement member contacts the cell seals and adheres the rear substrate and the front substrate to each other, wherein the reinforcement member is formed in a groove in each of the front and rear substrates, and each groove is configured to induce flow of the reinforcement member towards the cell seal; and
one or more inducing portions formed in one or more layers between the front and rear substrates.
10. The array of claim 9 , wherein the cell seals are formed of a glass frit, and the reinforcement member is formed of a resin.
11. The array of claim 9 , wherein each groove comprises a cross-sectional shape defined by a portion of a triangle.
12. The array of claim 9 , wherein each groove comprises a cross-sectional shape defined by a portion of a rectangle.
13. The array of claim 9 , wherein each groove comprises a cross-sectional shape defined by a portion of a circle.
14. The array of claim 9 , wherein each groove comprises a cross-sectional shape defined by a portion of an ellipse.
