Display panel, manufacturing method and display device

Abstract

The embodiment of the invention provides a display panel, a manufacturing method and a display device, and relates to the technical field of display. The occurrence probability of a color mixing phenomenon can be reduced. The display panel comprises a plurality of sub pixels, a lower base plate and a functional layer arranged on the lower base plate; a sunken part is formed in the position, corresponding to the sub pixels, of the functional layer, and a Micro LED is arranged in the sunken part; the lower base plate is close to the surface, relative to one side of the functional layer which deviates from the lower base plate, of a light-exiting face of the Micro LED; and the functional layer is used for preventing the at least part of light emitted from the Micro LED in one of the sub pixels incident on the side wall of the sunken part from emitting from another sub pixel adjacent to the sub pixel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method, and a display device. Background technique [0002] With the continuous improvement of display technology, people's requirements for display devices are also constantly improving. In various display technologies; in recent years, self-luminous display devices such as Micro Light Emitting Diodes (Micro LED) , has been widely used in various electronic devices including computers, mobile phones and other electronic products due to its advantages of self-illumination, thinness, low power consumption, high contrast, high color gamut, and flexible display. [0003] For self-luminous display devices, each sub-pixel is provided with a self-luminous unit, which is equivalent to a Lambertian light source, and its beam angle is relatively large; however, due to the large angle of light emitted by the self-luminous unit The light easily ent...

Problems solved by technology

[0003] For self-luminous display devices, each sub-pixel is provided with a self-luminous unit, which is equivalent to a Lambertian light source, and its beam angle is relatively large; however, due to the large angle of light emitted by the self-luminous unit The light easily enters the adjacent or other sub-pixels and exits, causing color mixing (Optical Cross-talk) and causing adverse effects on the display screen (for example, blurred picture, low color contrast, etc.)
