Abstract

An organic light emitting diode display panel is disclosed, which includes: a first substrate, having a display region and a non-display region; an organic light emitting layer disposed above the first substrate; and a plurality of spacers disposed above the first substrate, the spacers including a first spacer, a second spacer, a third spacer and a fourth spacer, the first spacer and the second spacer being adjacently located in the display region, and the third spacer and the fourth spacer being adjacently located in the non-display region, wherein a first minimum distance is between the first spacer and the second spacer, a second minimum distance is between the third spacer and the fourth spacer, and the first minimum distance is different from the second minimum distance. In addition, the present invention also disclosed an organic light emitting diode display device including the same.

Claims (32)

1. An organic light emitting diode display panel, comprising:

a first substrate, having a display region and a non-display region;

an organic light emitting layer disposed above the first substrate; and

a plurality of spacers disposed above the first substrate, the spacers comprising a first spacer, a second spacer, a third spacer and a fourth spacer, the first spacer and the second spacer being adjacently located in the display region, and the third spacer and the fourth spacer being adjacently located in the non-display region,

wherein a first minimum distance is between the first spacer and the second spacer, a second minimum distance is between the third spacer and the fourth spacer, and the first minimum distance is different from the second minimum distance.

2. The organic light emitting diode display panel as claimed in claim 1 , wherein at least one of the spacers has a surface, which is rough.

3. The organic light emitting diode display panel as claimed in claim 1 , wherein the first spacer and the second spacer are arranged along a direction, and the third spacer and the fourth spacer are arranged along the direction.

4. The organic light emitting diode display panel as claimed in claim 2 , wherein plural protrusions are formed on the surfaces, and at least two of the protrusions have different sizes.

5. The organic light emitting diode display panel as claimed in claim 1 , wherein a first electrode layer comprising plural first electrode units is further disposed above the first substrate, and the organic light emitting diode display panel further comprises a pixel defining layer disposed between the first electrode units.

6. The organic light emitting diode display panel as claimed in claim 5 , wherein the pixel defining layer has at least one recess corresponding to at least one of the spacers.

7. The organic light emitting diode display panel as claimed in claim 1 , wherein a size of the first spacer in the display region is different from a size of the third spacer in the non-display region.

8. The organic light emitting diode display panel as claimed in claim 1 , wherein the first minimum distance is greater than the second minimum distance.

9. An organic light emitting diode display panel, comprising:

a first substrate, having a display region and a non-display region;

an organic light emitting layer disposed above the first substrate; and

a first spacer and a third spacer disposed above the first substrate, wherein the first spacer is located in the display region, and the third spacer is located in the non-display region,

wherein a size of the first spacer is different from a size of the third spacer.

10. The organic light emitting diode display panel as claimed in claim 9 , wherein the size of the first spacer is greater than the size of the third spacer.

11. The organic light emitting diode display panel as claimed in claim 9 , wherein an area of a projection of the first spacer on the first substrate is different from an area of a projection of the third spacer on the first substrate.

12. The organic light emitting diode display panel as claimed in claim 11 , wherein the area of the projection of the first spacer is greater than the area of the projection of the third spacer.

13. The organic light emitting diode display panel as claimed in claim 9 , wherein a first electrode layer comprising plural first electrode units is further disposed above the first substrate, and the organic light emitting diode display panel further comprises a pixel defining layer disposed between the first electrode units.

14. The organic light emitting diode display panel as claimed in claim 13 , wherein the pixel defining layer has at least one recess corresponding to the first spacer or the third spacer.

15. The organic light emitting diode display panel as claimed in claim 9 , wherein the first spacer or the third spacer has a surface, which is rough.

16. An organic light emitting diode display device, comprising:

a driving unit;

an organic light emitting diode display panel electrically connecting to the driving unit, and comprising:

a first substrate, having a display region and a non-display region;

an organic light emitting layer disposed above the first substrate; and

a plurality of spacers disposed above the first substrate, the spacers comprising a first spacer, a second spacer, a third spacer and a fourth spacer, the first spacer and the second spacer being adjacently located in the display region, and the third spacer and the fourth spacer being adjacently located in the non-display region,

wherein a first minimum distance is between the first spacer and the second spacer, a second minimum distance is between the third spacer and the fourth spacer, and the first minimum distance is different from the second minimum distance.

17. The organic light emitting diode display device as claimed in claim 16 , wherein the first minimum distance is greater than the second minimum distance.

18. The organic light emitting diode display panel as claimed in claim 17 , wherein the first spacer and the second spacer are arranged along a direction, and the third spacer and the fourth spacer are arranged along the direction.
