ABSTRACT:
An LCOS display, including specially manufactured spacers, and a process for making the display, are disclosed. The spacers ensure a uniform cell gap along the entire display. The spacers occupy a region between pixels, such that they do not interfere with light modulation and are not visible during magnification. The spacers are manufactured using known deposition, lithography and etching techniques, and are made from widely available materials. The process results in a high yield of high-quality LCOS displays.
