Abstract

The invention relates to a Mini LED display module and a display panel. The Mini LED display module comprises a substrate with a driving circuit and a plurality of LED chips, the LED chips are arranged on the substrate in an array mode and electrically connected with the driving circuit, micro-nano structures are arranged on the LED chips, each micro-nano structure comprises a plurality of light guide media arranged in an array mode, the size between any two points on each light guide medium is smaller than the wavelength of light emitted by the corresponding LED chip, and the distance between any two adjacent light guide media is smaller than the wavelength of light emitted by the corresponding LED chip. According to the Mini LED display module, the micro-nano structure is arranged on the reflecting surface of the LED chip or the light emitting surface of the side, away from the substrate, of the LED chip, the light output efficiency of the LED chip can be remarkably improved through the micro-nano structure, the needed brightness can be obtained through few LED chips, therefore on the basis that the same brightness of the display module is guaranteed, the use number of the LED chips in the display module is reduced, and the production cost, the use power consumption and the heat productivity of the display module can be remarkably reduced.

Description

technical field [0001] The application belongs to the technical field of LED display, and in particular relates to a Mini LED display module and a display panel. Background technique [0002] Mini LED (Mini Light-Emitting Diode, Micro Light-Emitting Diode) as a new generation of display technology, has many current mainstream display technologies LCD (Liquid Crystal Display, Liquid Crystal Display), OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) Advantages that it does not have, such as OLEDs are prone to flask phenomenon when they work for a long time, and the yield rate of large-size OLEDs is low, making it difficult to achieve low-cost mass production. However, due to the contrast ratio of LCD, it is difficult to achieve high dynamic display. [0003] Due to the low light extraction efficiency of a single LED chip in the existing Mini LED, a large number of LED chips needs to be used, resulting in high power consumption and high user cost, and a larger...
