Abstract:
1. A liquid crystal display apparatus with touch input function, comprising: a first display transistor; a first display unit coupled to a first scanning line via the first display transistor; a touch transistor including a gate electrode coupled to a second scanning line, a first terminal, and a second terminal coupled to a sensing line; a first touch-sensing device including a first conductor coupled to the first terminal of the touch transistor, a second conductor coupled to the first scanning line and the gate of the first display transistor, and a first touch conductor configured to electrically connect the first conductor and the second conductor when a first sensing region of the liquid crystal display apparatus is touched; a touch-detecting circuit coupled to the sensing line, wherein a signal channel couples N sensing lines to the touch-detecting circuit, N is between 1 and 10, and the N sensing lines are connected in a loop manner; a second display unit coupled to a third scanning line; and a second touch-sensing device including a third conductor coupled to the first terminal of the touch transistor, a fourth conductor coupled to the third scanning line, and a second touch conductor configured to electrically connect the third conductor and the fourth conductor when a second sensing region of the liquid crystal display apparatus is touched.
