Display panel, driving method thereof, and display device

Abstract

The invention discloses a display panel, a driving method thereof and a display device. The display panel is used for achieving control over emergent rays with no polarizing film, lowering the cost ofa display product and increasing the transmittance of the display product. According to the display panel, a sub-pixel unit comprises a first electrode layer, a second electrode layer, a light gathering structure, a third electrode layer and a first light shielding layer arranged at the side, away from a liquid crystal layer, of the light gathering structure; the orthographic projection of the light gathering structure on a substrate covers the orthographic projection of a light incident region on the substrate, and the geometric center of the orthographic projection of the light gathering structure on the substrate coincides with the geometric center of the orthographic projection of the first light shielding layer on the substrate; in the initial state, the long axes of liquid crystal molecules are parallel to the substrate, the long axes of dark state liquid crystal molecules are perpendicular to the substrate, an arch pattern is formed at the region, close to the array substrate,of the illuminated state liquid crystal layer, and the long axes of the liquid crystal molecules in the region close to the color film substrate are parallel to the substrate; the refractive index ofthe long-axis direction of the liquid crystal molecules is equal to the refractive index of the light gathering structure, and the refractive index of the short-axis direction of the liquid crystal molecules is smaller than the refractive index of the light gathering structure.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] Liquid crystal displays have a series of advantages such as high color gamut, thinness, and fast response time, and are currently widely used display devices. Liquid crystal display has mature technology in theoretical research and practical technology, but the basic principle of display is to use liquid crystal to modulate polarized light to realize display. One display panel needs two polarizers up and down, and the liquid crystal changes the light. Polarization state, so that part of the polarized light can be emitted, and the other part of the polarized light cannot be emitted, so as to realize the control of the emitted light. To sum up, the liquid crystal display products in the prior art require polarizers, which affects the transmittance of the liquid crystal dis...
