Abstract
A receiver for an LCD source driver of an LCD panel includes a converter, a comparing circuit and a decoding circuit. The converter converts two pairs of differential current signals into two pairs of differential voltage signals. The comparing circuit is coupled to the converter for generating reference signals based on differences between the two pairs of differential voltage signals. The decoding circuit is coupled to the comparing circuit for generating data signals, clock signal, setting signals, and control signals based the reference signals.
Claims19
A receiver for a source driver of an LCD panel comprising:
- a converter for converting two pairs of differential signals from a first format into a second format;
- a comparing circuit coupled to the converter for generating reference signals based on differences between the two pairs of differential signals of the second format;
- and
- a decoding circuit coupled to the comparing circuit for generating data signals and control signals based on the reference signals.
A source driver for driving an LCD panel comprising:
- a receiver for receiving a plurality of differential signals, comprising:
- a comparator for comparing the plurality of differential signals and outputting a plurality of compared signals;
- and
- a decoder for generating a plurality of image data signals and a plurality of control signals in accordance with the plurality of compared signals;
- and
- a processing device for generating the driving signals to the LCD panel in accordance with the image data signals and the control signals, comprising:
- a data latch for latching the plurality of image data signals;
- a digital-to-analog-converter for converting the image data signals into a plurality of analog signals;
- and
- an output buffer for enhancing the driving ability of the analog signals.
