Problems solved by technology

The production of lines and patterns adopts the yellow photolithography process, which requires a large investment in equipment, high material costs, and high environmental pollution control costs
If the bending angle is large, the ITO is easy to break and break, and the reliability is not good
[0006] The insulating frame is used to define the luminous range and shape of the OLED. Traditionally, vacuum coating equipment can be used to coat SiO2, or coating equipment can be coated with PI, and then the insulating frame is produced by the yellow light etching process. The yellow light etching process equipment Large investment, high cost of materials, high cost of environmental pollution remediation

Abstract

The invention discloses a flexible OLED (organic light emitting diode) lighting panel. The lighting panel comprises flexible ultrathin glass at the bottom layer of the lighting panel; a silver nanowire transparent conductive film is printed on the flexible ultrathin glass; an ITO film is plated on the silver nanowire transparent conductive film; an insulating frame is printed on the upper edge ofthe ITO film; and an OLED is formed on the ITO film and the insulating frame by means of evaporation. According to the flexible OLED lighting panel of the invention, the ultrathin glass replaces PI toserve as a flexible substrate, so that a glass carrying substrate, a laser lift-off process and equipment can be omitted; and a water-oxygen barrier layer is not required to be plated, so that expensive vacuum coating equipment is omitted.

Description

technical field [0001] The invention belongs to the field of OLED lighting panels, and more specifically relates to a flexible OLED lighting panel and a manufacturing method thereof. Background technique [0002] OLED lighting is driven by low-voltage direct current, with a wide spectrum and high efficiency. It can provide a healthy and soft flat light source without flickering and blue-violet light, and can define any light-emitting shape; flexible OLED lighting panels can also be rolled into various shapes, and printed on the back. Various colors and patterns, suitable for high-end lighting design. Such as high-end modeling table lamps, standing lamps, artistic modeling lamps, interior lighting of high-end cars, tail lights and so on. [0003] The market promotion of traditional OLED lighting is not easy. The main reason is that the production cost of the traditional production method is too high, and it is easy to crack or break after bending, which seriously affects the...
