The invention discloses an LCOS (Liquid Crystal On Silicon) display which comprises a glass substrate unit, a silicon substrate unit and a circuit board, wherein an electrode layer is formed on the glass substrate unit, a common electrode wire is formed on the silicon substrate unit, the glass substrate unit and the silicon substrate unit are fitted through a frame sealant, the electrode layer is communicated with the common electrode wire on the inner side of the frame sealant, the circuit board and the silicon substrate unit are fitted, and the circuit board is communicated with the common electrode wire. The electrode layer is communicated with the common electrode wire, and the common electrode wire is further communicated with the circuit board, so that the communication between the electrode layer and the circuit board is achieved; meanwhile, due to the communication of the electrode layer and the common electrode wire on the inner side of the frame sealant as well as the protection effect of the frame sealant, the communication reliability of the electrode layer and the common electrode wire is also guaranteed, and the reliability of the LCOS display is improved. Furthermore, the miniaturization of the LCOS display is promoted, and the use ratios of the glass substrate unit and the silicon substrate unit are also increased.
Description
technical field [0001] The present invention relates to the technical field of displays, in particular to an LCOS display and a manufacturing method thereof. Background technique [0002] LCOS (Liquid Crystal on Silicon, liquid crystal on silicon) display is a new type of reflective projection display device, which uses semiconductor silicon crystal technology to control liquid crystal to "project" color images. Compared with transmissive LCD (Liquid Crystal Display) and DLP (Digital Light Procession) structures, LCOS displays have the characteristics of high light utilization efficiency, small size, high aperture ratio, and mature manufacturing technology. Full color performance. The above advantages make the LCOS display have great advantages in the future large-screen display application field. [0003] The manufacturing method of LCOS display in the prior art mainly comprises the following steps: [0004] First, a glass substrate and a silicon substrate are provided; ...
