Abstract
A display device includes a pixel, a data line, a scan line, a data driver, and a scan driver. The pixel is configured to display an image. The data line is configured to transmit data voltages to the pixel. The scan line is configured to transmit a scan signal to the pixel. The data driver is configured to: float the data line during a first period of a frame, apply, after the first period, a first data voltage to the data line during a second period of the frame, and apply, after the second period, a voltage waveform to the data line that varies the applied voltage from the first data voltage to a target voltage during a third period of the frame. The scan driver is configured to selectively apply the scan signal to the scan line.
Claims20
A display device, comprising:
- a pixel configured to display an image;
- a data line configured to transmit data voltages to the pixel;
- a scan line configured to transmit a scan signal to the pixel;
- a data driver configured to:
- float the data line during a first period of a frame,
- apply, after the first period, a first data voltage to the data line during a second period of the frame, and
- apply, after the second period, a voltage waveform to the data line that varies the applied voltage from the first data voltage to a target voltage during a third period of the frame;
- and
- a scan driver configured to selectively apply the scan signal to the scan line.
A method, comprising:
- receiving a video signal;
- displaying, via a pixel connected to a data line, an image corresponding to the video signal during a first period of a frame based on the video signal;
- floating, before the first period, the data line during a second period of the frame;
- and
- applying, via a data driver, a voltage waveform to the data line during a third period of the frame, the third period being disposed between the second period and the first period,
- wherein the voltage waveform varies from a first voltage to a target voltage.
A data driver, comprising:
- at least one processor;
- and
- at least one memory comprising computer code, the computer code being configured to, when executed by the at least one processor, cause the data driver at least to:
- float a data line connected to a pixel during a first portion of a frame of an image signal,
- apply, after the first portion, a data voltage to the data line during a second portion of the frame, and
- apply, after the second portion, a voltage waveform to the data line during a third portion of the frame, the voltage waveform varying from the data voltage to a target voltage.
