Abstract

The embodiment of the invention provides a display panel, device and method, an electrowetting microcavity unit and a light control substrate. The electrowetting microcavity unit comprises an electrowetting cavity and electrowetting liquid, wherein the electrowetting cavity is provided with a peripheral surface, a first light-transmitting bottom surface and a second light-transmitting bottom surface; the first light-transmitting bottom surface and the second light-transmitting bottom surface are used for packaging the two ends of the peripheral surface respectively; a partial space in the electrowetting cavity is filled with the electrowetting liquid; any two adjacent surfaces of the peripheral surface, the first light-transmitting bottom surface and the second light-transmitting bottom surface are insulated, at least two surfaces are provided with electrodes, and the electrode of at least one surface is a grounding electrode. According to the embodiment of the invention, light passesthrough the electrowetting liquid, and the angle of the incident surface and / or the emergent surface of the electrowetting liquid can be adjusted by controlling the electric field, so that the light is projected to different directions, binocular parallax is formed, and three-dimensional image display is realized; and moreover, light is not shielded, and the light utilization rate is high.

Description

technical field [0001] The present application relates to the field of display technology, in particular, the present application relates to a display panel, a device and a method, an electrowetting microcavity unit, and a light control substrate. Background technique [0002] Glasses-free 3D (three-dimensional) display utilizes the parallax characteristic of human eyes to obtain realistic three-dimensional images with space and depth without any auxiliary equipment (such as 3D glasses, helmets, etc.). [0003] Existing glasses-free 3D displays usually adopt light barrier technology or lenticular lens technology. [0004] Light barrier technology uses a barrier to separate light into left-eye and right-eye direction light to form binocular parallax to achieve stereoscopic image display, but it inevitably blocks part of the light, resulting in low light utilization, that is, the display brightness is low. Low. [0005] Lenticular lens technology is to make the image plane o...
