Embodiment Construction
[0046] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0047] figure 1 It is a schematic plan view of the first embodiment of the two-dimensional and three-dimensional display switching device of the present invention, figure 2 for figure 1 The sectional view of A-A in the middle. Such as figure 1 , figure 2 As shown, the two-dimensional and three-dimensional display switching device of this embodiment is composed of several liquid crystal lens units 100, and the several liquid crystal lens units 100 are arranged in a matrix, which is the same as the sub-pixels 200 arranged in a matrix on the liquid crystal display panel. Each liquid crystal lens unit 100 corresponds to at least one sub-pixel of the liquid crystal display panel. In actual use, one liquid crystal lens unit can also correspond to two, three or four sub-pixels in the liquid crystal display panel, that ...

The invention relates to a two-dimensional and three-dimensional display switching device, a manufacture method thereof and a liquid crystal display. The two-dimensional and three-dimensional display switching device comprises a plurality of liquid crystal lens units which are arranged in manner of matrix, wherein each liquid crystal lens unit comprises a first unit, a second unit and an elastic electrode which is arranged between the first unit and the second unit; liquid crystal is filled between the first unit and the elastic electrode; and each liquid crystal lens unit is also provided with a control electrode for driving the elastic electrode to deform to form into a liquid crystal lens. The invention adopts the mode that the structures of the liquid crystal lens units are formed by filling the liquid crystal into the elastic electrode, thereby being convenient for switching the two-dimensional display and three-dimensional display. The invention not only can realize an exact three-dimensional image, wherein the displayed three-dimensional image is not limited by watch distance, but also has the advantages of compact structure, simple control method, adjustable watch distance of the three-dimensional image, easy realization and low cost, etc.
Description
technical field [0001] The invention relates to a liquid crystal display and a manufacturing method thereof, in particular to a two-dimensional and three-dimensional display switching device, a manufacturing method thereof, and a liquid crystal display. Background technique [0002] At present, three-dimensional display technology is divided into several categories, such as electronic holography, multi-directional display and volumetric three-dimensional display, and each category can be subdivided into several types. Electron holography can perfectly record and reproduce light waves. It is in the initial research stage and requires huge storage and transmission space. Directional multi-channel display technology uses retro-reflective screens to separate the left and right eye image light so that they enter the left and right eyes of people respectively, including isolation barrier display, parallax display and moving slit display based on the switching method. The three-di...
