摘要

An organic light emitting display device includes a substrate having a display area displaying an image and a non-display area surrounding the display area; a camera disposition area provided within the display area; a panel identification area provided in the non-display area; and an upper protective layer covering the camera disposition area and the panel identification area.

說明書

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of Korean Patent Application No. 10-2019-0171592 filed on Dec. 20, 2019, which is hereby incorporated by reference in its entirety.

BACKGROUND Field of the Disclosure

The present disclosure relates to an organic light emitting display device, and more particularly, relates to a panel ID of a display device in which a camera is disposed in a display area.

Description of the Background

As an information-oriented society has advanced, the demand for display devices for displaying images has been increasing, and various types of display devices such as liquid crystal display devices and organic light emitting display devices have been utilized.

Such a display device may include a display panel in which a plurality of sub-pixels are disposed to display an image, and various driving circuits for driving the sub-pixels disposed in the display panel.

In addition, the display device may perform a function of detecting an object approaching the display panel, in addition to a function of displaying an image, to thereby perform input processing based on detection information, or may capture an object approaching the display panel to thereby provide a function of displaying a captured video or image through the display panel.

Accordingly, the display device may include a sensor such as a proximity sensor or a camera sensor depending on a required function. Such a sensor, for example, may be disposed in a bezel area where an image is not displayed in the display panel.

權利要求

What is claimed is:1. An organic light emitting display device comprising:a substrate having a display area displaying an image and a non-display area surrounding the display area;a first area provided in the display area;a second area provided in the display area and surrounding the first area; anda panel identification area provided in the non-display area and including a panel identification layer, a lower protection layer disposed on the identification layer and an upper protection layer disposed on the lower protection layer,wherein the first area is a portion where an opening penetrating the substrate is provided and a camera is disposed, andwherein the upper protective layer covers the first area, the second area and the panel identification area.2. The organic light emitting display device of claim 1, wherein the second area is disposed in contact with an outer edge of the opening.3. The organic light emitting display device of claim 1, wherein the upper protective layer covers a portion of a side surface of the opening and an upper portion of the second area.4. The organic light emitting display device of claim 3, wherein the upper protective layer prevents layer delamination in the opening.5. The organic light emitting display device of claim 4, wherein the upper protective layer includes at least one of benzocyclobutene (BCB) and photoacryl.6. The organic light emitting display device of claim 1, further comprising a thin film transistor provided in the display area excluding the first area and second area,wherein the thin film transistor includes a semiconductor layer, a gate electrode, source and drain electrodes, a gate insulating layer disposed between the semiconductor layer and the gate electrode, and an interlayer insulating layer insulating the gate electrode and the source and drain electrodes from each other.7. The organic light emitting display device of claim 6, further comprising a gate insulation layer on which the panel identification layer and the lower protective layer disposed in the panel identification area.8. The organic light emitting display device of claim 7, wherein the panel identification layer is disposed on a same layer as the gate electrode and is formed of a same material as the gate electrode.9. The organic light emitting display device of claim 7, wherein the panel identification layer has a panel ID engraved therein and the lower protective layer is positioned in the panel identification area.10. The organic light emitting display device of claim 9, wherein the panel ID includes at least one of numbers, letters and shapes.11. The organic light emitting display device of claim 7, wherein the lower protective layer is disposed on a same layer as the interlayer insulating layer.12. The organic light emitting display device of claim 11, wherein the lower protective layer is formed of a same material as the interlayer insulating layer.13. The organic light emitting display device of claim 7, wherein the upper protective layer covers the panel identification area and is in contact with the panel identification layer and the lower protective layer.14. The organic light emitting display device of claim 13, wherein the upper protective layer is removed in an upper portion of the display area excluding the opening and the second area.15. The organic light emitting display device of claim 13, wherein the upper protective layer covers an upper portion of the display area adjacent to the second area.16. The organic light emitting display device of claim 14, wherein the upper protective layer prevents a panel ID from being lost by a chemical solution when the upper protective layer on an organic light emitting element of the display area is removed by the chemical solution.17. The organic light emitting display device of claim 11, further comprising a second interlayer insulating layer positioned between the lower protective layer and the upper protective layer.18. The organic light emitting display device of claim 6, further comprising an organic light emitting element on the thin film transistor and electrically connected to the thin film transistor.19. The organic light emitting display device of claim 18, further comprising an encapsulation layer covering the organic light emitting element.20. The organic light emitting display device of claim 19, further comprising a touch sensor having at least one touch electrode disposed on the encapsulation layer.
