Abstract

The invention provides an electroluminescent display with an organic and inorganic mixed luminescent layer suitable for the technical field of panel display. The display comprises a TFT array backboard, the TFT array backboard is provided with a first electrode, and the first electrode is connected with a source or drain electrode of the TFT array backboard; the first electrode is provided with a pixel defining layer, the pixel defining layer comprises multiple pixel units, the pixel units comprise three sub pixel pits isolated from one another, and the sub pixel pits are placed on the first electrode so that part of the first electrode is exposed out of the pixel defining layer; the part, exposed out of the pixel defining layer, of the first electrode is provided with the organic and inorganic mixed luminescent layer which comprises a red light quantum dot luminescent layer, a green light quantum dot luminescent layer and a blue light organic luminescent layer; and a second electrode is arranged on the organic and inorganic mixed luminescent layer.

Description

technical field [0001] The invention belongs to the technical field of flat panel display, and in particular relates to an electroluminescent display containing an organic / inorganic mixed light-emitting layer and a preparation method. Background technique [0002] With the development of the information age, the importance of the display as a visual information transmission medium is further highlighted. In order to occupy a dominant position in the display field for a long time, displays are developing towards lighter, thinner, lower power consumption, lower cost and better image quality. [0003] Organic light-emitting diodes (OLEDs) have the advantages of self-illumination, fast response, wide viewing angle, high brightness, light and thin, etc., and their potential market prospects are optimistic by the industry. At present, OLED products that have entered the market are prepared by vacuum evaporation process, which requires high-precision masks, and the preparation pro...
