Abstract:
The present disclosure discloses a surface relief liquid crystal lenticular device, a manufacturing method therefor, and a display device with same. The liquid crystal lenticular device ( 60 ) includes an upper substrate module ( 161 ), a lower substrate module ( 171 ), a plano-concave lens module ( 64 ), a plurality of liquid crystal molecules ( 81 ), a sealing plastic structure ( 82 ), an electrically-conductive structure ( 83 ), and an external power supply (V). The lower substrate module ( 171 ) comprises a lower ITO electrode layer ( 62 ), a secondary ITO electrode ( 62 a ), an electrical blocking structure ( 62 b ), and several lower alignment targets ( 63 ). The upper substrate module ( 161 ) comprises an upper ITO electrode layer ( 72 ), a plurality of shading portions ( 75 ), and several upper alignment targets ( 73 ). A plurality of liquid crystal lenticular lenses is driven by a voltage to achieve the aim of 2D and 3D switchable display.

Claim (Index 23):
A method for manufacturing the surface relief liquid crystal lenticular device as claimed in  claim 1 , comprising:\n a first step: forming a lower ITO electrode layer, a secondary ITO electrode, an electrical blocking structure and several lower alignment targets on a lower transparent substrate through a photo-lithography process, so as to prepare a lower substrate module; forming an upper ITO electrode layer, a plurality of shading portions, and several upper alignment targets on an upper transparent substrate through a photo-lithography process, so as to prepare an upper substrate module; a second step: providing a plane mould, which has a mold structure opposite to that of a plano-concave lens module; filling the plane mould with liquid UV-cured resin through a process of precision inkjet printing; through precision photo-alignment to the lower substrate module in a vacuum cavity, precisely pressing the lower ITO electrode layer of the lower substrate module onto the plane mould and covering the liquid UV-cured resin; irradiating UV light to the liquid UV-cured resin in the plane mould, so as to cure the liquid UV-cured resin and mold the plano-concave lens module; and taking out the plano-concave lens module from the plane mould through a de-molding process, and fixedly arranging the plano-concave lens module on the lower ITO electrode layer of the lower substrate module; a third step: coating the surfaces of a plurality of concave lens surfaces and a plurality of spacing surfaces with alignment liquid through processes comprising spin, or dipping, or relief printing, or inkjet printing, as well as a process of heat drying, so as to generate a lower alignment film; and coating the surfaces of the upper ITO electrode layer and the plurality of shading portions with alignment liquid through processes of spin, or dipping, or relief printing, or inkjet printing, as well as a process of heat drying, so as to generate an upper alignment film; a fourth step: making an alignment direction of the upper alignment film parallel to a linear polarization direction of an image incident light through an alignment process, and making an alignment direction of the lower alignment film parallel to the long axes of switchable liquid crystal lenticular lenses through an alignment process; a fifth step: arranging a sealing plastic structure on a sealing plastic surface through processes of precision alignment, precision dispensing and UV pre-curing; a sixth step: drop filling a plurality of liquid crystal molecules into a concave lens surface through an On Drop Filling process; a seventh step: arranging an electrically-conductive structure on the secondary ITO electrode through processes of precision alignment and precision dispensing; and an eighth step: bonding the upper substrate module and the lower substrate module through processes of precision alignment and vacuum attaching, and irradiating UV light to make the sealing plastic structure cured, so as to form the surface relief liquid crystal lenticular device.
