Provided are a display device and a source driver. The source driver may perform a power down mode in response to any one of a vertical blank period, a horizontal blank period, a state in which the load of a panel is maintained at a preset value or less, a state in which a current supplied to the panel is maintained at a preset value or less, or a state in which resolution is maintained at a preset value or less. The source driver can realize the power down mode using various power options, thereby reducing power consumption.

Source driver

A display driving circuit is configured to select one of application of a pair of pixel driving signals to a pair of output terminals and charge sharing between the pair of output terminals by using charges discharged from a display panel.

Display driving circuit and display device

A liquid crystal display driving circuit and method. A data register block of a controller applies in advance a polarity control signal to data before the data are stored in latches of a data driver, exchanges the data, and then stores the exchanged data in the latches. Thereby, it is possible to provide multiplexers, which are otherwise required for respective channels, to one controller and to decrease the size of a chip.

Circuit for driving LCD device and driving method thereof

Embodiments of the present invention provide a method and apparatus for transmitting data between a timing controller and a source driver. In some embodiments, the method includes a bit error rate test (BERT) function for sensing an error rate in real time when data is transmitted and received between the timing controller and the source driver.
