Abstract

The invention relates to the field of semiconductor illumination, particularly to an integrated watertight OLED flat light source and a preparation method therefor. The integrated watertight OLED flat light source comprises a negative electrode glass substrate layer, an electronic transmitting layer, an optical output layer, a hole transport layer, a positive electrode conductive substrate, a packaging adhesive body, a negative electrode electric wire and a positive electrode electric wire, wherein the negative electrode glass substrate layer, the electronic transmitting layer, the optical output layer, the hole transport layer and the positive electrode conductive substrate are laminated together from the top to bottom in sequence; a whole body which is formed by the negative electrode glass substrate layer, the electronic transmitting layer, the optical output layer, the hole transport layer and the positive electrode conductive substrate in an accumulative manner is coated with the packaging adhesive body; the negative electrode glass substrate layer is connected with the negative electrode electric wire; and the positive electrode conductive substrate layer is connected with the positive electrode electric wire. The integrated watertight OELD flat light source has small size, high-level waterproof performance and good illumination effect; and the preparation method is simple to operate and can be widely popularized easily.

Description

technical field [0001] The invention relates to the field of semiconductor lighting, in particular to an integrated watertight OLED flat light source and a preparation method thereof. Background technique [0002] OLED is an excellent organic semiconductor lighting product. It has technical advantages such as large size, surface emission, extremely thin overall thickness, uniform brightness, and high color rendering. It is very suitable for uniform, soft and comfortable lighting occasions. But OLED has another important disadvantage: it is extremely sensitive to liquids such as water. OLED materials will be completely damaged and scrapped when they come into contact with water, which severely limits their wide application in optical lighting in outdoor landscapes and underwater places. In view of this situation, it is very necessary to design and invent an integrated watertight OLED panel light source with high waterproof level and which can be used underwater. Contents o...
