LCOS display (liquid crystal on silicon)
A liquid crystal on silicon (LCOS) display utilizes a silicon chip as a substrate and utilizes a standard CMOS process to form pixel cell matrices, integrated drivers, and other electronic devices on the silicon chip. The main structure of an LCOS display includes a light source module, an LCOS panel, and a color separation and combination optical system. The LCOS display thus comprises a first glass or plastic layer, an electrode layer, a liquid crystal layer, a second electrode layer, a patterned metal film layer, and a second glass or plastic layer. A pixel of the LCOS display includes a single micro-mirror, along with its associated layers. The LCOS display is thus an array of pixels, including hundreds or thousands of individual pixels. LCOS displays use polarized lenses to control the transmission of light, known as light modulation, to individual pixels within the pixel array. LCOS displays are thus sometimes referred to as light modulators. The electrodes embedded in the glass or plastic layers allow an electric field to be applied across the liquid crystal material. The liquid crystal thus acts as a dynamic polarizing medium. LCOS display can be divided into three-panel LCOS displays and single-panel LCOS displays according to the type of optical engine. Liquid crystal on silicon (LCoS) display devices provide high resolution, high brightness and high contrast and are utilized in high-definition television, near-eye viewing devices, and projectors. An advantage of the LCOS display is its utilization of the CMOS process, since the CMOS process is well developed in the present semiconductor industry. As a result, high stability and reliability can be achieved when compared to the LCD. The difference between an LCOS display and a conventional thin film transistor-liquid crystal display (TFT-LCD) is materials used for forming substrates. Unlike liquid crystal display (LCD) whose the front and rear plates are made of glass, LCOS employs a silicon plate and glass plate between which liquid crystal is filled. The structure of LCOS can provide displays not only meeting the requirement for compactness of portable products, but also having high resolution.
