Abstract

This invention relates to a plate display structure and control, which belongs to plate display technique field. The controller in this invention comprises digit transducer, I#+[2] C interface controller, PWM wave generator and adopts configuration register to output each display control signals and clock signals with different display resolution and field frequency and writing-in types. It adopts PWM wave generator to generate the impulse wide modulation drive signals to provide the high voltage excitation signals of FED and PDP. It generates the reverse control signals for the LCD display through scanning controller.

Description

technical field [0001] The invention relates to a driving and control technology of a flat panel display, in particular to a display controller having a PWM waveform generator and a configurable register, which can be used for various flat panel displays such as LCD, FED, and PDP, and belongs to the field of flat panel display technology. Background technique [0002] Now flat-panel displays have become the mainstream of information display technology development, and various types of flat-panel display devices such as LCD, PDP, FED, OLED, etc. are competing to develop, the image display quality is getting better and better, and the application fields are getting wider and wider. In terms of system, any flat panel display system consists of three parts: video signal processing circuit, display module and interface control circuit. Among them, the video signal processing circuit is the same for any flat-panel display, and there are many general-purpose circuits for designers ...
