Abstract
A liquid crystal display apparatus with touch input function includes a display unit coupling to a first scanning line, a touch transistor, a touch-sensing device, and a touch-detecting circuit coupling to a sensing line. The touch transistor includes a gate coupling to a second scanning line, a first terminal, and a second terminal coupling to the sensing line. The touch-sensing device includes a first conductor coupling to the first terminal of the touch transistor, a second conductor coupling to the first scanning line, and a touch conductor configured to electrically connect the first conductor and the second conductor when a sensing region of the liquid crystal display apparatus is touched.
