Embodiment Construction

[0041] A method for driving a silicon-based liquid crystal display, converting an external video signal into a serial video digital signal matching the interface of the SSD1961 chip, converting the above-mentioned serial video digital signal into a corresponding parallel video digital signal through the SSD1961 chip, and The above-mentioned parallel video digital signals are used to generate driving timing to drive the LCD on silicon. Through a series of conversions on the parallel video signal, the silicon-based liquid crystal display is driven to display at a resolution of 320*240*18bit. The driving method of the silicon-based liquid crystal display realizes that different types of external video signals can drive the silicon-based liquid crystal display, which is relatively convenient; and the connection between digital signals is perfected.

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 SSD1961 chip, the serial video digital signals are converted into corresponding parallel video digital signals through the SSD1961 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, in particular to a method for driving a silicon-based liquid crystal display. Background technique [0002] Liquid Crystal on Silicon (LCOS) is a very small matrix liquid crystal display device based on reflection mode. This matrix is ​​fabricated on a silicon chip using CMOS technology. [0003] According to 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 the video signal of MCU8080 mode, which is a serial 8-bit video signal. [0004] When driving the LCOS screen, different drive devices are selected for the input video signals of different formats. The connection between digital signals is not perfect and it is troublesome to select a drive device when inputting digital video signals of different formats. Contents of the invention [000...
