Abstract

The invention discloses an organic light-emitting diode display and a preparation method thereof and a display device. The organic light-emitting diode display comprises a substrate and a plurality of sub-pixel units arranged on the substrate. Each sub-pixel unit comprises a first electrode, a light-emitting function layer and a second electrode, which are arranged on the substrate in sequence. The surface, away from the substrate, of the first electrode comprises a plurality of first grooves in equal-width equal-interval parallel arrangement. The cross section of each first electrode is in a zigzag shape. The depth of each first groove is smaller than the maximum distance between the surface, away from the substrate, of the first electrode and the substrate; the widths of the first grooves in different sub-pixel units are not totally same; and the distance between adjacent two first grooves in different sub-pixel units are not totally same. The organic light-emitting diode display can enable color saturation of the sub-pixels in different colors to be different, so that chroma requirement of the display terminal can be met, and display effect is improved.

Description

technical field [0001] The invention relates to the field of organic optoelectronics, in particular to an organic light emitting diode display device, a preparation method and a display device. Background technique [0002] In recent years, with the rise of organic light-emitting diode (OLED) technology, OLEDs are increasingly used in various light-emitting display fields. OLED display technology has self-illumination, wide viewing angle (over 175 degrees), fast response speed (1μs), high luminous efficiency, wide color gamut, low working voltage (about 3-10V), thin panel (thickness can be less than 1mm), Low cost, large-size flexible panels can be produced, and simple production process, so that OLED display technology has broad application value, and its market share is gradually increasing. As a kind of OLED display field, the top-emitting OLED device is widely used due to its advantages such as high aperture ratio. However, the cathode of the top-emitting OLED device m...
