Embodiment Construction

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0029] In the prior art, in order to enhance the bending Needle, a deep hole (Deep Hole, DH) will be etched in the bending area (Pad bending area), and then the organic photoresist material (Organic Deep Hole Material, ODH) will be filled in the DH. The thickness of ODH is 1.5 microns ( μm); however, when bending, since the stress neutral plane is not on the wiring layer in the pad bending area, the stress release will be uneven during bending, which will cause the wiring layer ...

Abstract

The invention discloses a light-emitting panel and a display device. The light-emitting panel comprises a substrate, a transistor layer, an organic layer and a wiring layer, wherein the substrate comprises a display area, a non-display area, and a bending area connected with the display area and the non-display area; the transistor layer is arranged on the substrate and relative to the display area and the non-display area; the organic layer is arranged on the substrate and relative to the bending area; the wiring layer is arranged on the organic layer; the vertical height of the organic layeris greater than that of the transistor layer, so that the breakage of the wiring layer is effectively reduced, and the yield of the light-emitting panel is increased.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a light-emitting panel and a display device. Background technique [0002] In recent years, as Organic Light Emitting Diode (OLED) has many excellent characteristics such as self-illumination, low energy consumption, wide viewing angle, rich colors, fast response and flexible screen preparation, etc. Great interest, considered to be the next generation display technology with great potential. [0003] In the prior art, in order to enhance the bending Needle, it will etch a deep hole (Deep Hole, DH) in the bending area (Pad bending area), and then fill the DH with organic photoresist material (Organic Deep Hole Material, ODH); but when bending The wiring layer on the ODH is broken, which seriously affects the yield of the light-emitting panel. [0004] Therefore, there are defects in the prior art, and improvement is badly needed. Contents of the invention [0005...
