Abstract
Provided is a driving circuit for a liquid crystal display which is suitable for reducing a chip size and has improved noise immunity in a circuit which uses a level shifter and is constructed with a channel array. The driving circuit includes: the level shifter which is disposed in a previous stage of a channel region and shifts up a level of a data signal output from a buffer to output the data signal to the channel region; and the channel region which processes an output data of the level shifter in a format requested by a system and outputs a final data in a high or low format, and wherein the level shifter is disposed in a region excluding the channel region.
Claims6
A driving circuit for a liquid crystal display which includes a channel region array of the same structure circuit having two or more operating voltage ranges, comprising:
- a level shifter which shifts up a level of a data signal output from a buffer to output the data signal to the channel region;
- and
- the channel region which processes an output data of the level shifter in a format requested by a system and outputs a final data in a high or low format, and
- wherein the level shifter is disposed in a region excluding the channel region.
