Abstract
A switching signal generator of an active matrix display is disclosed. The switching signal generator includes at least one delay device connected to the switches of the active matrix display. The delay device consists of many delay units connected in series for receiving a source switching signal and correspondingly generating a plurality of target switching signals controlling the switches. There is a constant phase shift between any two successive target switching signals so that the switches are switched on one by one at regular intervals.
Claims14
A switching signal generator for use with a plurality of switches of an active matrix display, comprising a plurality of delay units electrically connected to said plurality of switches, and generating a plurality of target switching signals in response to a source switching signal for controlling signals to be outputted to an active matrix portion of said active matrix display via said plurality of switches,
- wherein there is a constant phase shift between every two successive target switching signals, thereby switching on said plurality of switches and outputting said signals to said active matrix portion in sequence.
A switching signal generator for use in an active matrix display, comprising a first generator portion receiving a source switching signal and generating a set of first target switching signals, and a second generator portion receiving said source switching signal and generating a set of second target switching signals,
- wherein there is a first phase shift between every two of said first target switching signals and there is a second phase difference between every two of said second target switching signals for switching on active matrix units of said active matrix display in sequence.
An active matrix display comprising:
- an active matrix portion comprising a plurality of active matrix units arranged in columns and rows;
- a first switch portion comprising a plurality of first switches which are switched on in response to respective first switching signals to allow first signals to be outputted to said active matrix units;
- and
- a first switching signal generator sequentially asserting said first switching signals in response to a source switching signal, thereby switching on said first switches and allowing said first signals to be outputted to said active matrix units in sequence.
