Abstract

The invention relates to a liquid crystal box structure of a LCOS (Liquid Crystal on Silicon) micro display device and a manufacturing method of the liquid crystal box structure. The liquid crystal box structure is of a laminar structure, and comprises an upper electrode layer, a liquid crystal material layer, a nanorod and a silicon-based substrate layer, wherein the upper electrode layer is graphene film plate glass; the nanorod is a zinc oxide or titanium dioxide nanorod. The manufacturing method comprises the following steps: (A) preparing the silicon-based substrate layer; (B) preparing the nanorod on the silicon-based substrate layer to obtain a silicon-based substrate layer with the nanorod; (C) jointing the graphene film plate glass with the silicon-based substrate layer provided with the nanorod to assemble a liquid crystal box; (D) filling the liquid crystal box with a liquid crystal material to form a liquid crystal material layer. Compared with the prior art, the liquid crystal box structure has the advantages that the transmission is high, the thickness of a liquid crystal box is easy to control, and the working temperature can be up to 60 DEG C, so that the display performance of the device is greatly enhanced.

Description

technical field [0001] The invention relates to a microdisplay device, in particular to a structure of a liquid crystal box of an LCOS microdisplay device and a manufacturing method thereof. Background technique [0002] LCOS (Liquid Crystal on Silicon) is a relatively mature advanced technology. It is a new type of LCD display made on single crystal silicon, and it is an emerging technology that organically combines LCD and CMOS integrated circuits. LCOS has the characteristics of high resolution, reflective imaging, and low price. This technology first appeared in the late 1990s. Its first molded products were developed by Aurora Systems in 2000. Because the product has the characteristics of high resolution, high aperture ratio, and reflective imaging, it immediately attracted people's attention, and many companies began to conduct research and development. Among them are companies such as Sony, JVC, Canon, Intel, Philips, and UMC. [0003] The structural characteris...
