Abstract
A display device includes a data driver having i data output terminals (i being a natural number greater than 1) and outputting data voltages to the i data output terminals in accordance with a source output enable signal provided from a timing controller, an output controller connected between the i data output terminals and i data lines, and i garbage switches respectively connected to the i data lines and connecting the i data lines to a ground terminal at a power input timing when a power supply voltage is applied to the display device, and interrupting the connection between the i data lines and the ground terminal at a timing later than an output timing of a first source output enable signal provided from the timing controller after the power input timing.
Claims7
A display device comprising:
- a data driver having i data output terminals (i being a natural number greater than 1), the data driver outputting data voltages to the i data output terminals in accordance with a source output enable signal provided from a timing controller;
- an output controller connected between the i data output terminals and i data lines;
- and
- i garbage switches respectively connected to the i data lines and that connects the i data lines to a ground terminal at a power input timing when a power supply voltage is applied to the display device, and that interrupts the connection between the i data lines and the ground terminal at a timing later than an output timing of a first source output enable signal provided from the timing controller after the power input timing,
- wherein the output controller comprises:
- a first output control switch controlled in accordance with a first switch control signal provided from the timing controller, and connected between a data output terminal and a data line which correspond to each other;
- a second output control switch controlled in accordance with a second switch control signal provided from the timing controller, and connected between a data output terminal and a data line corresponding to another data output terminal disposed adjacent to the data output terminal;
- and
- a charge share switch controlled in accordance with a third switch control signal provided from the timing controller, and connected between data lines disposed adjacent to each other, and
- wherein one of the first and second output control switches is turned on in a part of a period when the i garbage switches are connected to the ground terminal.
