Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0028] In the prior art, when making a curved screen, it is necessary to attach the flexible organic light-emitting display panel to the curved substrate for fixing, refer to Figure 1a , Figure 1a It is a schematic diagram of 3D bonding of organic light-emitting display panels in the prior art. When the organic light-emitting display panel 1 is bonded to the rigid substrate 2, the bending regions 11 on both sides of the flexible display panel 1 are bent due to force. Refer to Figure 1b and Figure 1c , Figure...

Abstract

The embodiment of the invention discloses an organic light emitting display panel which comprises an array substrate, a polarizer formed above the array substrate, and a binding region formed on the array substrate along one side of a first direction, wherein bending regions are formed on the binding region along two sides of a second direction, a covering layer covers the bending regions, and thefirst direction is perpendicular to the second direction. According to the technical solution provided by the embodiment of the invention, the problem of display failure of the display panel caused by the breakage of metal film layers in the bending regions at two sides of a chip on film of the display panel easily caused by the 3D bonding of an existing curved display screen can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of organic light emitting displays, and in particular, to an organic light emitting display panel. Background technique [0002] The substrate of an organic light emitting display panel (Organic Light Emitting Display, OLED) can be configured as a flexible material, so it is often used in the field of flexible display. For example, flexible OLED can be used for curved mobile phone screens or wearable devices. [0003] When the flexible OLED is used for a curved screen, in 3D bonding, it is necessary to bond the flexible OLED to a curved rigid substrate, only a pair of opposite edges of the four side edges of the curved rigid substrate are curved surfaces, and the middle The area is flat to realize fixed OLED bilateral curved surface display. When the edges on both sides of the flexible OLED are squeezed by force, the edges on both sides will bend to form a bending area, and the plane a...
