Organic light-emitting display panel

Abstract

The invention discloses an organic light-emitting display panel. The organic light-emitting display panel comprises a substrate, and a light-emitting pixel array which is located on the substrate andcomposed of a plurality of light-emitting pixels. Each light-emitting pixel comprises a convex structure layer, a light-emitting element, a planarization layer and a micro-lens structure which are sequentially stacked on the substrate, each convex structure layer comprises at least one convex structure of which the convex direction deviates from the substrate, and at least one convex curved surface of which the convex structure is in contact with the light-emitting element; and the vertical projections of each micro lens structure and each convex structure on the substrate are overlapped withthe vertical projections of the light-emitting elements on the substrate. Through the coupling effect of the convex structures and the micro lens structures, the component of parallel light in light output from the micro lens structures can be increased, and therefore, the display brightness of the organic light-emitting display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel. Background technique [0002] In recent years, organic light-emitting display panels have gradually become the mainstream on mobile display terminal screens and display screens. The organic light-emitting display panel includes a plurality of sub-pixels arranged in an array, and each sub-pixel includes a pixel driving circuit and a light emitting element electrically connected to the pixel driving circuit. [0003] Since part of the light emitted by the organic light-emitting display panel has a large angle of light that cannot reach the human eye, there is a waste of light, which leads to the problem of high power consumption of the organic light-emitting display panel. In order to ensure that the large-angle light emitted by the organic light-emitting display panel converges to In the perspective of the observer, in the prior art, a mi...

Problems solved by technology

[0004] However, when a convex lens is set above an OLED pixel, the light emitted from a light-emitting surface with an area similar to that of the convex lens cannot be focused into a parallel or approximately parallel beam through the convex lens, and there will still be a considerable part of the light with a large angle. The ground is emitted and cannot reach the human eye, resulting in more light loss
