Abstract: A speaker device for a display device is disclosed. The speaker device includes: a magnet layer, disposed inside a housing of the display device; and a metal coil layer, disposed on a color filter glass of the display device, and configured to provide a motive force to the color filter glass to generate an amplitude according to a magnetic field reaction generated when a current flows through the metal coil layer.

Abstract: A touch device includes a touch panel, a driving circuit, a sensing circuit, and a controller. The touch panel includes a first scan line cascaded with a first diode, a second scan line cascaded with a second diode, and a sense line interlaced with the first scan line and a second scan line. The first scan line and the second scan line are cascaded between a first node and a second node. The driving circuit generates a scan voltage across the first node and the second node according to a scan signal. The sensing circuit detects a capacitance of the sense line according to a detection signal to generate a receive signal. The controller generates the scan signal and the sense signal and determines the location of a touch point on the touch panel according to the scan voltage and the receive signal.
