Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0030] figure 1 It is a schematic structural diagram of a display panel in the prior art, and a Micro-LED 12' and a barrier wall 13' are formed on a substrate 11' of the display panel. Micro-LED12' has strabismus light L1' that emits to the adjacent Micro-LED12', which will form a mixed light area on the light output side of the adjacent Micro-LED12', causing the color mixing of Micro-LED12' and affecting the adjacent Micro-LED12'. Display of LED12'. In addition, because of the emission of squint light L1' betwe...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises: a substrate; and a plurality of Micro-LEDs which are arranged on one side of the substrate. A retaining wall structure is arranged between every two adjacent Micro-LEDs; the retaining wall structure comprises a shading part and a lens part which are arranged in a stacked mode; the lens part is made of a transparent material; and the shading part is made of a light-absorbing material. The invention provides the display panel and the display device so as to solve the problem of color mixing between adjacent Micro-LEDs and improve the display effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In recent years, with the high-definition development of flat-panel displays such as mobile phones and TVs, the requirements for high-performance LED displays have further increased. The size of the LED element used as a light source has been miniaturized from about 1 mm in the past to 100 to 500 μm called a small LED display, and the size of a micro LED (Micro-LED) display is 100 μm or less. In addition to the previous characteristics of high brightness and wide color gamut, micro LED displays that can achieve higher refinement will also replace liquid crystal, plasma displays, organic EL displays, etc. [0003] The existing Micro LED substrate structure is usually provided with an array of Micro-LEDs, and barrier walls are provided between adjacent Micro-LEDs to improve light emission and light extrac...
