Abstract

The invention relates to the technical field of display equipment, and discloses a mirror surface display screen and a preparation method; the mirror surface display screen comprises a substrate, a flat layer and a pixel defining layer; a plurality of opening areas distributed in an array mode are formed in the pixel defining layer; a positive electrode, and a light emitting layer arranged on oneside, deviating from the flat layer, of the positive electrode are formed in each opening area in the pixel defining layer in sequence; a negative electrode is arranged on one side, deviating from theflat layer, of the pixel defining layer, and the negative electrode sinks into the opening area at the opening area; an auxiliary electrode layer is arranged on one side, deviating from the pixel defining layer, of the negative electrode; and the thickness of the position, opposite to the opening area, of the auxiliary electrode layer is larger than or equal to 0 and smaller than the thickness ofthe part, outside the opening area, of the auxiliary electrode layer. By virtue of the mirror surface display screen, the light transmittance is improved by reducing the thickness of the position, relative to the light emitting layer, of the auxiliary electrode, and the contrast ratio of the mirror surface display screen is further improved.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a mirror display screen and a preparation method. Background technique [0002] The thickness of the cathode in the top-emission OLED display screen structure in the prior art is relatively thin, resulting in excessive resistance and high power consumption of the OLED display screen, resulting in uneven brightness of the screen. Contents of the invention [0003] The invention provides a mirror display screen and a preparation method. The mirror screen display increases the light transmittance by reducing the thickness of the auxiliary electrode and the relative part of the light-emitting layer, and further improves the contrast of the mirror screen display. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A mirror display, comprising: [0006] Substrate substrate; [0007] a flat layer disposed on one s...
