Abstract

The invention provides a liquid crystal on silicon (LCOS) structure and a manufacturing method. The manufacturing method for the LCOS structure comprises a step of forming a conducting material layer in a sealant, thereby utilizing the conducting material layer to implement the conduction between a glass substrate unit and a circuit board through an LCOS substrate unit. The invention further provides an LCOS structure manufactured by utilizing the manufacturing method for the LCOS structure. Compared with the prior art, the manufacturing method for the LCOS structure not only can effectively shorten a manufacturing process of LCOS products, but also can solve the technical problems that conducting resin is removed or broken and the conducting resin is easy to oxidize in the prior art.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an LCOS structure and a manufacturing method. Background technique [0002] The LCOS (Liquid Crystalon Silicon) structure is a new type of reflective projection display device, which uses semiconductor silicon technology to control the liquid crystal and then "projects" a color picture. Compared with the transmissive LCD (Liquid Crystal Display) and DLP (Digital Light Procession) structures, the LCOS structure has the characteristics of high light utilization efficiency, small size, high aperture ratio, and mature manufacturing technology, which can easily achieve high resolution and full color which performed. The above-mentioned advantages make the LCOS structure have great advantages in the field of large-screen display applications in the future. [0003] figure 1 A flowchart of a fabrication method of a common LCOS structure in the prior art is shown. Depend on fig...
