Embodiment Construction

[0019] The present invention proposes a large-aperture liquid crystal lens array using a composite dielectric layer such as figure 1 As shown, the structure from top to bottom is: upper substrate 1, common electrode 2, upper dielectric layer 3, liquid crystal layer 4, high dielectric layer 5, raised material layer 6, pixel electrode 7, lower substrate 8, Composite dielectric layer 9 .

[0020] Composite dielectric layer manufacturing method among the present invention is as figure 2 Shown: 1. The ITO glass substrate is spin-coated with a raised material layer and pre-baked; 2. The spin-coated ITO glass substrate is placed on the mask plate and irradiated obliquely with an ultraviolet lamp; 3. The mask plate and The ITO glass substrate is rotated together by an azimuth angle and then irradiated with an oblique ultraviolet lamp. The oblique irradiation of the ultraviolet lamp needs to be performed several times, and the azimuth angle of each rotation is the same, until the azi...

Abstract

The invention provides a large-diameter liquid crystal lens array adopting a composite dielectric layer. The liquid crystal lens array comprises an upper substrate, a common electrode, a high dielectric layer, a liquid crystal layer, the composite dielectric layer, a pixel electrode and a lower substrate from top to bottom. The liquid crystal layer is prepared from a nematic liquid crystal material. The upper substrate and the lower substrate are glass substrates with plane-transparent electrodes. The composite dielectric layer comprises the high dielectric layer and a protruding material layer, and the two materials are mutually dissolved. A set of complete technological production process is provided for the composite dielectric layer. Accordingly, a large-diameter liquid crystal lens array with the diameter at the millimeter level can be produced, and meanwhile the manufacturing process difficulty and the production cost of a liquid crystal lens are lowered.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a device comprising a two-dimensional liquid crystal lens array of a composite dielectric layer of two materials. Background technique [0002] Among the many naked-eye lens technologies, liquid crystal lens technology is highly praised for its unique and excellent characteristics: liquid crystal lenses are tunable, and can realize continuous adjustment of lens focal length; liquid crystal molecular movement is very sensitive to external electric fields, making liquid crystal The lens has the characteristics of low power consumption; on the premise that the surface of the liquid crystal layer remains unchanged, the liquid crystal lens only adjusts the light wave by changing the direction of the director in the liquid crystal layer, and is less affected by the external environment, so the stability is higher. [0003] At present, liquid crystal lenses are often used to make mic...
