Abstract

An organic light emitting diode (OLED) display comprises a first substrate and a second substrate configured to comprise a pixel area and a non-pixel area other than the pixel area, a sealing member configured to adhere the first substrate and the second substrate together, reinforcing materials filled into the non-pixel area of the first substrate and the second substrate, and an accommodation unit configured to accommodate some of the reinforcing materials within at least one of the first substrate and the second substrate corresponding to the non-pixel area. A method of manufacturing the OLED display comprises: preparing a mother substrate, including a plurality of display panels and cutting lines between two adjacent display panels; cutting the mother substrate into separated display panel units; forming grooves on a side of each display panel unit; and filling reinforcing materials in a non-pixel area of the display panel units, some of the reinforcing materials flowing into the grooves.

Claims (17)

1. An organic light emitting diode (OLED) display device including a plurality of separate display panel units, each display panel unit comprising:

a first substrate and a second substrate configured to form a pixel area and a non-pixel area other than the pixel area in said each display panel unit;

a sealing member for adhering the first substrate and the second substrate together in said each display panel unit;

reinforcing materials filled into the non-pixel area of the first substrate and the second substrate in said each display panel unit; and

an accommodation unit for accommodating some of the reinforcing materials within at least one of the first substrate and the second substrate corresponding to the non-pixel area of said each display panel unit;

wherein the accommodation unit includes grooves formed in both sides of each of the first substrate and the second substrate of said each display panel unit.

2. The organic light emitting diode (OLED) display of claim 1 , wherein the groove are formed by lateral processing using grinders, each grinder comprising penett wheels.

3. The organic light emitting diode (OLED) display of claim 2 , wherein the grinders comprise:

a first grinder for processing the sides of the first substrate of said each display panel unit; and

a second grinder for processing the sides of the second substrate of said each display panel unit.

4. The organic light emitting diode (OLED) display of claim 3 , wherein the groove is formed in a vertical direction (y-axis) relative to a planar direction (x-axis) of the first and second substrates of said each display panel unit.

5. The organic light emitting diode (OLED) display of claim 2 , wherein the groove is formed in a vertical direction (y-axis) relative to a planar direction (x-axis) of the first and second substrates of said each display panel unit.

6. The organic light emitting diode (OLED) display of claim 1 , wherein the groove is formed by etching.

7. The organic light emitting diode (OLED) display of claim 6 , wherein the groove is formed in a vertical direction (y-axis) relative to a planar direction (x-axis) of the first and second substrates of said each display panel unit.

8. The organic light emitting diode (OLED) display of claim 1 , wherein the groove is formed in a vertical direction (y-axis) relative to a planar direction (x-axis) of the first and second substrates of said each display panel unit.

9. The organic light emitting diode (OLED) display of claim 1 , wherein the sealing member comprises frit.

10. The organic light emitting diode (OLED) display of claim 1 , wherein the reinforcing materials comprise epoxy-based materials.
