Abstract

The invention provides a liquid crystal lens, a stereo display device, a display method and a manufacturing method. The liquid crystal lens comprises a first substrate, a second substrate, a liquid crystal layer, spacers and a variable-color structure, and the liquid crystal layer, the spacers and the variable-color structure are arranged between the first substrate and the second substrate. An orthographic projection, on the first substrate or the second substrate, of the variable-color structure at least covers orthographic projections, on the first substrate or the second substrate, of the spacers. The variable-color structure is switchable between a transparent state and a black state. When a display panel displays black images, the variable-color structure can be controlled to be in the black state to reduce light reflection of the spacers, and accordingly light spots are avoided. When the display panel displays white images, the variable-color structure can be controlled to be in the transparent state, and consequently the problem of display dark areas in a region of the spacers due to light transmittance differences of the spacers and liquid crystal is avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal lenses, in particular to a liquid crystal lens, a stereoscopic display device, a display method and a manufacturing method. Background technique [0002] The liquid crystal lens is used in the display field, and has the advantages of simple control, high reliability and low driving voltage, and has huge potential applications. However, in the design process, due to the large thickness of the liquid crystal layer of the liquid crystal lens, it is necessary to use a larger support ball to support the thickness of the liquid crystal cell, a photo spacer (columnar spacer) or a ball spacer (spherical spacer), that is, a spacer. The spacer has a certain influence on the outgoing direction of the light emitted by the display panel, so it will change the light intensity distribution in different directions in the viewing area, which will lead to a decrease in the contrast of the display effect and ...
