Abstract
A display device includes: a display panel including a plurality of pixels; a source driver for outputting a target initialization voltage in an analog format to the pixels through sensing lines; and a timing controller for providing the source driver with a data control signal including packet information associated with the target initialization voltage. The packet information is in a digital format. The source driver includes a digital-analog converter which generates the target initialization voltage in the analog format, based on the packet information.
Claims20
A source driver comprising:
- an intra interface which receives a data control signal and outputs packet information associated with a target initialization voltage extracted from the data control signal, wherein the packet information is in a digital format;
- a digital-analog converter which generate the target initialization voltage in an analog format, based on the packet information, and
- a logic controller disposed between the intra interface and the digital-analog converter, wherein the logic controller generates a first control signal for controlling the digital-analog converter, based on the packet information.
