Abstract
The invention discloses a micro-LED display panel, a manufacturing method, a master plate and a display device. The micro-LED display panel includes: a substrate substrate, a temperature compensation layer located on one side of the substrate substrate, and a limiting layer located on the side of the temperature compensation layer away from the substrate substrate. On the side, the limiting layer includes a plurality of barrier walls. In the direction perpendicular to the base substrate, the barrier wall includes a first surface on the side close to the light-emitting surface and a second surface on the side away from the light-emitting surface. The second surface is larger than and covers The orthographic projection of the first surface on the plane where the base substrate is located; the orthographic projection of the barrier wall on the plane where the base substrate is located at least partially covers the orthographic projection of the temperature compensation layer on the plane where the base substrate is located, and the temperature compensation layer is used to adjust the local area of the barrier wall temperature. The side of the retaining wall of the micro-LED display panel provided by the present invention is larger than the side close to the light-emitting surface, which can improve the utilization rate of light, and is beneficial to improving the light-extracting efficiency and light-extracting effect of the micro-LED display panel.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a micro LED display panel, a manufacturing method, a master plate and a display device. Background technique [0002] Micro LED (Micro LED) display panel is a new generation of display technology, which has higher brightness, better luminous efficiency and lower power consumption than the existing OLED technology, and has occupied the main high-end TV market. Usually, in the micro-LED display panel, the retaining walls located at both ends of the micro-LEDs have the problem of angle setting and manufacturing difficulty, which leads to the problem of low light extraction efficiency of the micro-LED display panel. Contents of the invention [0003] In view of this, the present invention provides a micro-LED display panel, a manufacturing method, a master plate and a display device. The temperature compensation layer is used to adjust the temperature of the retai...
