Super-definition flexible light-emitting display and preparation method thereof

Abstract

The invention relates to a super-definition flexible light-emitting display and a preparation method thereof. According to the preparation method of the ultra-clear flexible light-emitting display, the fluorescent powder with the set color is evaporated on a tungsten oxide layer and a lithium fluoride layer to form a color light DBR layer, so that the color purity of emitted light can be improvedwhile the half-wave width value corresponding to a light-emitting spectrum is reduced, and the display definition is further improved. Moreover, the super-definition flexible light-emitting display obtained by adopting the preparation method can be bent and can be applied to various scenes. Besides, in the super-definition flexible light-emitting display system provided by the invention, when theultraviolet light irradiator emits ultraviolet light with different intensities and wavelengths to irradiate the super-definition flexible light-emitting display, the super-definition flexible light-emitting display can emit light with different colors, so that conversion and display of patterns are completed.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to an ultra-clear flexible light-emitting display and a preparation method thereof. Background technique [0002] Under the existing technology, commercial luminous signboards generally use LED lamp beads to luminously display. This display method has low resolution and generally uses a rigid backplane that cannot be bent and cannot adapt to various application scenarios. [0003] Therefore, it is a technical problem to be solved urgently in this field to provide a bendable flexible light-emitting display capable of adapting to various application scenarios. Contents of the invention [0004] The purpose of the present invention is to provide an ultra-clear flexible light-emitting display and its preparation method, so as to solve the problems existing in the light-emitting display in the prior art that it cannot be bent and cannot adapt to various application scenarios. [0005...
