Abstract
A display control circuit applies to a LCoS panel including pixel units and a substrate. The display control circuit includes a pixel memory array circuit and a driving circuit. The pixel memory array circuit includes pixel memory units. A projection of the pixel memory array circuit on the substrate is in a projection of the pixel units on the substrate. The driving circuit includes a row driving circuit and a column driving circuit. A projection of the driving circuit on the substrate is outside the projection of the pixel units on the substrate. The driving circuit provides a modulation signal and pixel data. The pixel memory array circuit modulates the pixel data by the modulation signal to provide a pixel display voltage to each of the pixel units.
