Embodiment Construction

[0039] A driving method for a silicon-based liquid crystal display, which converts an external video signal into a serial video digital signal matching the interface of the SSD1960 chip, and converts the above serial video digital signal into a corresponding parallel video digital signal through the SSD1960 chip, and The above-mentioned parallel video digital signal generates a driving sequence to drive the silicon-based liquid crystal display. Through a series of conversions to the parallel video signal, the silicon-based liquid crystal display is driven to display with a resolution of 320*240*18bit. The driving method of the silicon-based liquid crystal display screen realizes that different types of external video signals can drive the silicon-based liquid crystal display screen, which is more convenient; and the docking between digital signals is improved.

[0040] The driving method of a liquid crystal on silicon display screen of the present invention will be further descri...

Abstract

The invention discloses a method for driving a liquid-crystal-on-silicon display screen. The method for driving the liquid-crystal-on-silicon display screen converts external video signals into serial video digital signals matched with the interface of an SSD1960 chip, the serial video digital signals are converted into corresponding parallel video digital signals through the SSD1960 chip, and the liquid-crystal-on-silicon display screen is driven according to the parallel video digital signals. The method for driving the liquid-crystal-on-silicon display screen achieves the fact that the liquid-crystal-on-silicon display screen can be driven by the external video signals of different types, convenience is achieved, and the butt joint between digital signals is perfected.

Description

Technical field [0001] The invention relates to the technical field of driving a silicon-based liquid crystal display screen, in particular to a method for driving a silicon-based liquid crystal display screen. Background technique [0002] Liquid Crystal on Silicon (LCOS) is a very small matrix liquid crystal display device based on a reflective mode. This kind of matrix is ​​fabricated on a silicon chip using CMOS technology. [0003] In view of the characteristics of the LCOS screen, it is necessary to use parallel RGB video digital signals to drive the LCOS screen. The traditional digital video signal is a video signal in MCU8080 mode, which is a serial 8-bit video signal. [0004] When driving the LCOS screen, different driving devices are selected for the input video signals of different formats. The docking between the digital signals is not perfect and the driving device needs to be selected when inputting digital video signals of different formats, which is more troublesom...
