Problems solved by technology

[0003] Currently, the display module includes red organic light emitting elements, blue organic light emitting elements and green organic light emitting elements, and each organic light emitting element is formed of organic light emitting materials of corresponding colors. However, the lifespan of the red organic light-emitting material is short, which makes the display module prone to blue color cast, which affects the display effect of the display module.

Abstract

The invention discloses a display module, a preparation method of the display module, a display device and the display module. The display module comprises: a substrate; an organic light-emitting element layer on the substrate, the organic light-emitting element layer including a plurality of organic light-emitting elements; a packaging layer which is positioned on one side, deviating from the substrate, of the organic light-emitting element layer; and a light adjusting layer which is arranged on one side, deviating from the organic light-emitting element layer, of the packaging layer, whereinthe light adjusting layer comprises a plurality of protruding structures arrayed in the first direction and the second direction, the first direction intersects with the second direction, in the direction away from the substrate, the sectional areas, parallel to the substrate, of the protruding structures are decreased progressively, and the distance between every two adjacent protruding structures ranges from 380 nanometers to 550 nanometers. According to the display module, the blue color cast phenomenon of the display module can be improved, and the display effect of the display module isimproved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module, a method for preparing the display module, and a display device. Background technique [0002] Organic Light Emitting Display (OLED) display modules are widely used in mobile phones, televisions, personal digital assistants, digital cameras, Various consumer electronic products such as notebook computers and desktop computers have become the mainstream of display applications. [0003] At present, the display module includes red organic light-emitting elements, blue organic light-emitting elements and green organic light-emitting elements. Each organic light-emitting element is formed of an organic light-emitting material of a corresponding color. A blue color cast occurs, affecting the display effect of the display module. Contents of the invention [0004] The invention provides a display module, a preparation method of the display module and a display de...
