Abstract
An embodiments of the present disclosure provides a display device including: pixels disposed to be connected to scan lines and data lines; and a data driver configured to supply a data signal to the data lines via output lines. The data driver includes: a signal generator configured to generate the data signal to supply the data signal to channel lines; and a first amplifier and a second amplifier connected in parallel between each of the channel lines and each of the output lines.
Claims15
A display device comprising:
- pixels disposed to be connected to scan lines and data lines;
- and
- a data driver configured to supply a data signal to the data lines via output lines,
- wherein the data driver includes:
- a signal generator configured to generate the data signal to supply the data signal to channel lines;
- a plurality of amplifiers comprising a first amplifier and a second amplifier connected in parallel between each of the channel lines and each of the output lines, the output lines always being connected to alternative ones of the amplifiers,
- wherein the first amplifier and the second amplifier disposed in an i-th channel, where i is an integer greater than or equal to 0, are alternately connected to an i-th output line;
- a first transistor connected between the first amplifier and the i-th output line;
- and
- a second transistor connected between the first amplifier and an i-th channel line,
- wherein the second transistor is turned on before the first transistor and stays turned on when the first transistor turns on such that a turned-on period of the second transistor partially overlaps a turned-on period of the first transistor.
