Disclosed are a driver circuit for a display, which is capable of a two-stage charge sharing operation, and an operating method thereof.

Charge sharing driver circuit for display and operating method thereof

A display driving device for driving a display panel, including a gate line, a data line intersecting with the gate line, and a pixel defined by the gate line and the data line, includes a data driver inputting an image signal to the pixel through the data line, a panel test unit determining the occurrence or not of an error of the gate line or the data line, and a switching unit selectively connecting the data driver or the panel test unit to the display panel.

Display driving device and display driving method

The present disclosure provides a technology for a level shifter that allows the selection of a single-stage level shifter or a two-stage level shifter by a simple alteration to wiring. When the single-stage level shifter is selected, some circuits may remain as dummy circuits.

Level shifter including dummy circuit and method of manufacturing the same

The present disclosure discloses a display device that performs a read operation corresponding to a touch based on a multipoint interface (MPI) protocol. In the display device, a microcontroller and a plurality of drivers share MPI buses and perform the read operation for a touch, and turning on of reception buffers may be efficiently controlled by providing a wake-up signal by a selected driver designated by a read command of the microcontroller to unselected drivers at the time of completion of transmission of touch data.
