Abstract

The embodiment of the invention provides a cover plate and a preparation method thereof and a display device and relates to the technical field of display. The problem can be solved that a cover platereflects light so that light rays can enter an array substrate and the performance of the array substrate can be influenced. The cover plate comprises a first substrate and an auxiliary cathode whichis arranged on the first substrate and further comprises a wrapping layer which is arranged at the side, away from the first substrate, of the auxiliary cathode, and the wrapping layer wraps the auxiliary cathode; the wrapping layer is provided with multiple columnar patterns and touch holes; a conductive layer is arranged at the side, away from the first substrate, of the wrapping layer and electrically connected with the auxiliary cathode through the touch holes.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a cover plate, a preparation method thereof, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display devices have attracted extensive attention due to their advantages of thinness, lightness, low power consumption, high response, and high resolution. Top-emitting OLEDs can effectively solve the problems of reduced aperture ratio and brightness reduction caused by complex pixel circuits. At the same time, the microcavity effect in the top-emitting OLED structure can also be used to improve the color gamut of OLED display devices. display effect. [0003] Such as figure 1 As shown, the top emission OLED display device in the prior art includes an array substrate 10 and a cover plate 20; the array substrate 10 includes a TFT (Thin Film Transistor, thin film transistor) (not marked in the figure), a pixel defini...
