Abstract

The invention provides a color light-emitting element, a display panel and a manufacturing method, the color light-emitting element comprises a light-emitting device layer and a color conversion film layer, the light-emitting device layer emits first light, the color conversion film layer is arranged on one side of a light-emitting surface of the light-emitting device layer, and the color conversion film layer comprises a blocking part, a color conversion unit and a reduction unit, the color conversion units and the reduction units are distributed in the color conversion film layer in an array mode and are arranged at intervals through a blocking part, first light emitted by the light-emitting device layer is emitted into second light and third light through the color conversion units, and the luminous flux ratio of the first light emitted by the light-emitting device layer on the light incident face and the light emergent face of the reduction units is 3: 5-7: 10. The embodiment of the invention can effectively reduce the problem of light leakage and avoid light loss.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a color light-emitting element, a display panel and a manufacturing method. Background technique [0002] Micro-LED display technology refers to a display technology that uses self-luminous micron-scale LEDs as light-emitting pixel units and assembles them on a drive panel to form a high-density LED array. Compared with the existing organic light-emitting diodes ( Organic Light-Emitting Diode, OLED) technology, Micro-LED has the advantages of higher brightness, better luminous efficiency and lower power consumption. [0003] At present, in order to realize the color display of the Micro-LED display panel, a color light-emitting element with a single-primary color LED as the light-emitting source is usually used, and a color conversion film layer is arranged on the light-emitting side of the single-primary color LED, and the color conversion film layer is inside th...
