Abstract: A display device capable of driving at low speed includes a display panel, on which display lines each including a plurality of pixels are formed, a driver unit for driving the pixels, and a timing controller which controls an operation of the driver unit and includes a first control logic unit and a second control logic unit. When a mode conversion control signal of an on-level is input during a normal drive, in which a length of one frame is set to P, the first control logic unit expands a length of one frame for a low speed drive to (n×P), where n is a positive integer equal to or greater than 2, assigns a length P to each of n sub-frames included in the one frame for the low speed drive, and controls the operation of the driver unit in an interlaced low speed driving scheme.

Abstract: A display device with built-in touch sensors comprises: a display panel with built-in touch sensors; and a touch driver that converts a sensed voltage of the touch sensors into sensed data, wherein the touch driver comprises: an enable signal generator that compares the sensed voltage with a preset offset voltage and outputs an enable signal at a first level if the sensed voltage is higher than or equal to the offset voltage and outputs the enable signal at a second level if the sensed voltage is lower than the offset voltage; and an analog-to-digital converter that converts the sensed voltage into the sensed data when the enable signal is at the first level.
