Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the invention to those skilled in the art, and the present invention will only be defined by the appended claims. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. It will be understood that when an element such as a layer, region or substrate is referred to as being "formed on" or "disposed on" another element, it can be directly on the other element or present middle element. In contrast, when an element is referred to a...

Abstract

The invention relates to an organic light-emitting display device capable of preventing adjacent pixels from being shorted out. The organic light-emitting display device comprises a substrate and a pixel defining layer, wherein the pixel defining layer forms a continuous grid structure; pixel units are formed in the continuous grid structure; and an isolating structure for preventing the adjacent pixel units from being shorted out is arranged in the pixel defining layer. According to the organic light-emitting display device provided by the invention, by the isolating structure arranged on the pixel defining layer, the problem that an existing OLED device easily generates a transverse short circuit is effectively solved; and the existing device efficiency can be kept.

Description

technical field [0001] The present invention relates to an organic light-emitting display device, in particular to an organic light-emitting display device capable of preventing adjacent pixels from short-circuiting and a preparation method thereof. Background technique [0002] Organic Light-emitting Diode (OLED) has the advantages of active luminescence, high luminous efficiency, fast response time, low operating voltage, wide viewing angle, high contrast, wide operating temperature range, and flexible display, so it is known as the successor. The third generation of display technology after CRT and LCD. [0003] OLED pixel patterning is mainly formed by vacuum evaporation and masking, while adjacent sub-pixels use cured organic photoresist as isolation barriers. In the actual process, the organic photoresist often uses a positive photoresist, and the slope angle made at the edge of the pattern is relatively small, so the slope angle is very gentle after baking and curing...
