PDLC grating of LCD equipment and making method

Abstract

The invention discloses a PDLC raster and a manufacture method of an LCD device, wherein the raster structurally comprises a first base plate, a second base plate, a first electrode layer and a second electrode layer, the first electrode layer is arranged on the upper surface of the first base plate, the second electrode layer is arranged on the lower surface of the second base plate, and PDLC material is infused in a palisade groove formed by a palisade light resistance insulating object to be disposed to a polymer and liquid crystal droplets which are arranged between the first electrode layer and the second electrode layer. When an electric field is applied, the PDLC raster presents a full transparent state; when the electric field is not applied, the PDLC raster forms a light shield slit and a light transmission slit and presents the raster characteristic, thus, two display functions of the transparent display state and the raster characteristic can be realized in the way that theelectricity is applied or not applied, the consuming quantity of the polymer and liquid crystal can be saved, the manufacture process is simplified, and the LCD quality can be improved simultaneously.

Description

technical field [0001] The general concept of the present invention relates to a liquid crystal display device, in particular to a PDLC (Ploymer Dispersed Liquid Crystal) grating with an improved structure and a manufacturing method thereof. Background technique [0002] With the continuous development of liquid crystal technology, liquid crystal gratings are being studied extensively and deeply. Since this device has electric field controllability, it has a good application prospect in the fields of diffractive optics, projection display, optical switch and so on. However, the manufacture of liquid crystal devices requires many special processes, such as orientation treatment of liquid crystal molecules, control of cell thickness, sealing of cells, patching, etc., which complicates the manufacturing process and increases the manufacturing cost. The PDLC grating, through the electric field to adjust the refractive index of the liquid crystal, realizes the light scattering i...

Problems solved by technology

[0005] In the process of forming the PDLC grating 11 (that is, during the process of the ultraviolet light 12 irradiating the PDLC grating 11 through the mask plate 10), along with the continuous polymerization of the polymerized monomer in the light-transmitting region 115, the polymerized monomer in the opaque region 114 The polymerization reaction cannot be completely transferred to the light-transmitting region 115, and the liquid crystal 120 is not completely present in the light-impermeable region 114, and a little polymer 121 is bound to remain, so the light-impermeable region 114 becomes not transparent enough, affecting the PDLC grating 11 The effect of using it, so it will produce blurring in the LCD image
