Abstract: A touch screen includes a first electrode layer, an insulating layer on a first electrode layer, and a second electrode layer on the insulating layer. The first electrode layer or second electrode layer includes first sensing electrode columns and second sensing electrode columns. The first sensing columns include first sensing electrodes having sub-electrodes. The second sensing electrode columns are alternately arranged with the first sensing electrode columns and include second sensing electrode. The sub-electrodes of one of adjacent first sensing electrodes are electrically connected to sub-electrodes of another one of the adjacent first sensing electrodes, respectively.

Abstract: A data driver includes shift registers, sampling latches, holding latches, and a data sensing unit. The shift registers generate sampling pulses by shifting a source start pulse in response to a source sampling clock. Each of the sampling latches receives current data and stores the current data in response to each of the sampling pulses. Each of the holding latches receives the current data stored in each of the sampling latches, and stores the received current data in response to a source output enable signal. The data sensing unit receives the current data corresponding to an i-th sampling latch of the sampling latches or an i-th holding latch of the holding latches (i is a positive integer) and previous data stored in the i-th sampling latch or the i-th holding latch, compares the current data with the previous data, and generates control data based on the comparison result.

Abstract: An input sensing unit includes sensing electrodes. Each of the sensing electrodes includes: first electrodes arranged in a column extending in a first direction; a second electrode extending in the first direction; first sensing lines connected to the first electrodes, the first sensing lines extending in the first direction; and a second sensing line connected to the second electrode, the second sensing line extending in the first direction. The first sensing lines are connected to first pad portions. The second sensing line is connected to a second pad portion. The second pad portions or some of the first pad portions are disposed between a first pad portion among the first pad portions and the second pad portion, the first pad portion being connected to a first sensing line closest to the second sensing line among the first sensing lines.
