Abstract
A touch control screen includes a plurality of sensing units having first sensing electrodes and second sensing electrodes. Each of the first sensing electrodes includes at least one first trunk channel extending along a first direction and a plurality of first branch electrodes electrically connected to the first trunk channel. Each of the second sensing electrodes includes at least one second trunk channel extending along a second direction and a plurality of second branch electrodes electrically connected to the second trunk channel. The second branch electrodes and the first branch electrodes are alternately arranged, so that a sensing signal change amount of the touch control screen tends to change linearly.
