Problems solved by technology

[0009] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the heterosexual screen body is difficult to cut in the prior art, so as to provide a freely cuttable OLED screen body. Due to the use of a flexible conductive substrate, not only can it be cut into various shape, and no photolithography process is required in the preparation process, only a common mask is required, the process flow is short and the cost is low

Abstract

The invention provides a free-cutting OLED and an OLED screen and a preparing method. The free-cutting OLED is composed of a flexible conductive substrate, an organic illuminating unit with which the flexible conductive substrate is continuously covered and a cathode film layer; the free-cutting OLED screen is cut to form OLED simple grains, an anode FPC binding part and a cathode FPC binding part are arranged on the two sides of the OLED simple grains respectively to form the OLED screen. Dual-face binding is used in the OLED screen prepared with the method, routing is free inside the screen, non-illuminating areas do not exist in the edge, and therefore the illuminating area proportion is large.

Description

technical field [0001] The present invention relates to the technical field of organic electroluminescent screen (OLED screen) protection, in particular to a freely cuttable OLED screen, an OLED device prepared by cutting the OLED screen formed by cutting the OLED screen, and Fabrication methods of OLED devices. Background technique [0002] After nearly 30 years of development, OLED devices (English full name Organic Light Emitting Device, referred to as OLED) as the next generation of lighting and display technology, has a wide color gamut, fast response, wide viewing angle, no pollution, high contrast, planarization , thin and light, etc., have been applied to a certain extent in lighting and display. [0003] Existing OLED screens generally deposit various organic layers on a glass substrate. During the preparation process, photolithography is first used to form the display area, and then a mask process is used to form the organic layer in each display area. When cuttin...
