Abstract: A display apparatus includes a display panel, a touch sensing unit, and a touch driving circuit. The touch sensing unit includes a transmission touch line. The touch driving circuit provides a touch driving signal to the transmission touch line. The touch driving circuit may include a switch group and a control switch group. The switch group may include a plurality of switch devices, each of which has one end connected to the transmission touch line. The control switch group may be connected to the other end of at least a portion of the switch devices, include a plurality of control switch devices and a capacitor device, and receive a driving voltage and a ground voltage. The touch driving signal has N voltage levels, where N is a natural number of 3 or more.

Abstract: A coarse lock detector for a delayed locked loop (DLL) is disclosed. The coarse lock detector includes multiple detection cells. Each detection cell receives a delayed clock phase and an output of a previous detection cell as inputs. To increase time for the output of the previous detection cell to propagate, the detection cells are arranged in groups such that the output from the previous detection cell is generated by a detection cell which is more than one detection cell previous.
