Abstract
A capacitive touch display device includes a stylus, a display panel, and a capacitive touch unit. The stylus touches the display panel by clicking to input a touch signal and contacts the capacitive touch unit at a contact area. The capacitive touch unit is disposed on the display panel and includes a plurality of first sensing series and a plurality of second sensing series. Each of the first sensing series includes a plurality of first sensing pads electrically connected to one another. A pitch between any two adjacent first sensing pads is P. The second sensing series intersect the first sensing series. The contact area contacted by the stylus has a contact width D, and the ratio of the contact width D to the pitch P between any two adjacent first sensing pads satisfies the following ratio condition: 1.4≦(D/P)≦1.6.
