Abstract

The invention discloses an IMITO structure of an OLED, the IMITO structure comprises a glass substrate, a shadow elimination layer and a conductive layer, the shadow elimination layer is arranged between the conductive layer and the glass substrate, the shadow elimination layer is arranged on the glass substrate, and the conductive layer is arranged on the shadow elimination layer. The shadow elimination layer comprises a TiO2 film layer and a SiO2 film layer, the TiO2 film layer is arranged on the glass substrate, the SiO2 film layer is arranged on the TiO2 film layer, and the conductive layer is arranged on the SiO2 film layer. According to the invention, the purpose of shadow elimination is achieved by plating TiO2 and SiO2 materials under the ITO film layer, that is, the development and visual effects of the OELD are improved through the shadow elimination (IMITO) technology. The invention further discloses an OLED shadow elimination coating method which comprises the steps of raw material cleaning, TiO2 coating, SiO2 coating, ITO coating, film layer polishing, cleaning inspection and packaging shipment, and the glass substrate is sequentially subjected to the procedures of raw material cleaning, TiO2 coating, SiO2 coating, ITO coating, film layer polishing, cleaning inspection and packaging shipment on the conveying roller way.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an OLED IMITO structure and an OLED shadow-eliminating coating method. Background technique [0002] With the diversified development of display technology, OLED, as the frontier of current display technology, has begun to have a huge impact on traditional LCD products with the characteristics of ultra-thin, low energy consumption, wide viewing angle, and high-quality image quality, especially for mid-to-high-end displays. market, will gradually replace LCD. OLED refers to an organic semiconductor that is composed of an extremely thin organic material coating and a glass substrate and emits light when current passes through it, and has self-luminous characteristics. And our company has 20 years of experience in coating technology, and in 2016, we have started to develop and mass-produce the important components needed for OELD products - glass substrates with conduc...
