Embodiment 1

[0026] Figure 5 A schematic structural diagram of the liquid crystal light valve provided by the first embodiment of the present invention is shown, and for convenience of description, only parts related to this embodiment are shown.

[0027] refer to Figure 5 , the liquid crystal light valve mainly includes a first substrate 501 and a second substrate 502, an electrode layer 503, a barrier layer 504 and an alignment layer 505 are sequentially pasted on the opposite surfaces of the first and second substrates, respectively. A liquid crystal layer 506 is arranged between the alignment layers on the two substrates, and the liquid crystal layer 506 is composed of liquid crystal molecules. It can be understood that the ends of the upper and lower substrates are sealed by a sealing member 507 so as to form a liquid crystal cell that can accommodate liquid crystal molecules. A plurality of spacer balls 508 for supporting the first and second substrates are scattered in the liquid...

Abstract

The invention provides a liquid crystal light valve, a manufacturing method for the same, 3D (three-dimensional) glasses with the same and liquid crystal display equipment with the same, which are applicable to the field of 3D display. The liquid crystal light valve comprises a first substrate and a second substrate, an electrode layer, a barrier layer and an orientation layer are respectively and sequentially attached to opposite surfaces of the first substrate and the second substrate, a liquid crystal layer is arranged between the orientation layer attached to the first substrate and the orientation layer attached to the second substrate, a plurality of separating balls are scattered in the liquid crystal layer, each separating ball is provided with a plurality of blind holes, the separating balls are wrapped in the orientation layers, a wrapping layer is formed on the surface of each separating ball, and orientation layer materials are filled in the blind holes. The separating balls are firmly locked on the substrates by the orientation layers, and cannot spring along with change of attraction between the first substrate and the second substrate when the liquid crystal light valve works under driving voltage of a certain frequency, so that noise cannot be generated, a user wearing the glasses with the liquid crystal light valve cannot be interfered by noise, and fine seeing and hearing quality is ensured.

Description

technical field [0001] The invention belongs to the field of 3D display, and in particular relates to a liquid crystal light valve and a manufacturing method thereof, as well as 3D glasses and liquid crystal display equipment with the liquid crystal light valve.
