Disclosed are a display device and a driving method thereof. A reference compensation voltage for compensating for a node voltage of each pixel for an image holding period after a refresh period for which image data is input in a low-speed driving mode is set. Then, the node voltage of each sub-pixel is compensated for using a corresponding reference compensation voltage on at least one frame basis at each start time and each end time of the image holding period, thereby preventing low image quality and reducing power consumption.

Display device and driving method thereof

Disclosed herein are a display device for low-speed driving and a driving method thereof. The display device according to embodiments of the present disclosure may set a reference compensation voltage for compensating a node voltage of each pixel during an image holding period after a refresh period where image data are input at the time of low-speed driving, and may compensate a node voltage of each sub pixel on the basis of a unit of at least one frame during each image holding period between the refresh periods, thereby making it possible to prevent a deterioration of image quality and reduce electricity consumption.

Display device for low-speed driving and driving method thereof

Disclosed is a printed circuit unit that includes a flexible member which has an upper surface and a lower surface and includes a first end and a second end. An output pad is disposed at the first end and is implemented to be connected to a bent display panel. A connecting unit is disposed at the second end and is implemented to be connected to a system board, and a drive chip is located between the output pad and the connecting unit.

Chip on printed circuit unit and display apparatus comprising the same

A touch sensor integrated type display includes a display panel including a touch screen having touch sensors, a data driving circuit for driving data lines of the display panel, and a timing controller for generating a control signal for controlling a potential of an output terminal of the data driving circuit in vertical blank periods between adjacent vertical periods. The control signal selectively floats source output channels of the data driving circuit or selectively sets a potential of the source output channels to a predetermined voltage in the vertical blank periods.
