Embodiment 1

[0029] Such as figure 1 The liquid crystal photocontrol device shown, its manufacture method is as follows:

[0030] A method for manufacturing a 2D and 3D switchable liquid crystal light controller, comprising the following steps:

[0031] S1. First sputter a layer of indium tin oxide lower pattern conductive layer 2 on the lower glass substrate 1, after sputtering a layer of indium tin oxide lower pattern conductive layer 2 on the lower glass substrate 1, and then pass the yellow light process or etching paste process to oxidize The patterned conductive layer 2 under the indium tin oxide is trimmed, so that the patterned conductive layer 2 under the indium tin oxide is consistent with the shape of the lower glass substrate 1, and the patterned conductive glass under the indium tin oxide is formed after the two are bonded together;

[0032] S2. Further, continue laying a layer of zigzag microstructure pattern substrate layer 3 on the formed patterned conductive glass under t...

Embodiment 2

[0041] Such as figure 1 The shown liquid crystal photocontroller includes an upper glass substrate 7 and a lower glass substrate 1, wherein a patterned conductive layer 8 on indium tin oxide is arranged below the upper glass substrate 7, and then a patterned conductive layer 8 is placed on the upper glass substrate 7. Continue to set a layer of polyimide space ball mixture 6, the set polyimide space ball mixture 6 is made by fully mixing polyimide liquid and space balls with a diameter of 5-8um, and then on the lower glass substrate 1 A layer of indium tin oxide lower patterned conductive layer 2 that is completely consistent with indium tin oxide upper patterned conductive layer 8 is provided on it, and then a zigzag microstructure patterned substrate layer is continuously arranged on the lower indium tin oxide patterned conductive layer 2 3. A layer of polyimide alignment layer 4 is also arranged on the set microstructure pattern substrate layer 3, and finally the polyimide ...

Abstract

The invention provides a 2D and 3D switchable liquid crystal light control device and its manufacturing method, by sputtering a layer of indium tin oxide lower pattern conductive layer on the lower glass substrate; laying on the formed indium tin oxide lower pattern conductive glass A layer of zigzag microstructure pattern substrate layer; continue to lay a layer of polyimide alignment layer on the formed microstructure pattern glass substrate to form a microstructure pattern lower glass substrate with polyimide layer; on the upper glass substrate A layer of patterned conductive layer on indium tin oxide is sputtered on the substrate; a layer of polyimide space ball mixture is printed on the formed patterned conductive glass on indium tin oxide, and the glass on polyimide space ball mixture is formed after curing Substrate; use frame glue to form an internal liquid crystal box, and vacuum infuse liquid crystal through the reserved liquid crystal filling port; the liquid crystal light control device of the present invention improves the optical transmittance, and makes up for the use of prism columnar film to switch 2D display content resolution The defect of halving the rate.

Description

technical field [0001] The invention relates to the technical field of 2D and 3D switching, in particular to a 2D and 3D switchable liquid crystal light controller and a manufacturing method thereof. Background technique [0002] With the gradual popularization of high-resolution display screens, the refinement of picture display has exceeded the resolution ability of human eyes, but the display content is flat display without layering. Therefore, three-dimensional display is bound to become the development trend of display in the future. At present, 3D display in the market is mainly obtained by wearing 3D glasses, which greatly reduces the experience and convenience of users. Therefore, naked-eye stereoscopic display is the mainstream of 3D display in the future. [0003] At present, naked-eye 3D display is mainly realized by light barrier technology or lenticular lens technology. Light barrier technology products can realize free switching between 2D / 3D. When performing 2...
