A display apparatus including a display panel, a touch sensing unit including first and second transmission touch lines, and a touch driving circuit to apply first and second touch driving signals to the first and second transmission touch lines, respectively, in which the touch driving circuit includes a first switch group including a first sharing switch device having one end connected to the first transmission touch line, and a second switch group including a second sharing switch device having two ends respectively connected to the second transmission touch line and another end of the first sharing switch device, and the touch driving circuit is configured to turn on the sharing switch devices during a first period such that the touch driving signals have a first voltage level, and turn on the sharing switch devices during a second period such that the touch driving signals have a second voltage level.

Display apparatus having touch driving circuit for generating driving signals for different levels

A display apparatus includes a display panel; a touch sensing unit (TSU) on the display panel and including first and second transmission touch lines (TTL); and a touch driving circuit (TDC). The TDC applies first and second touch driving signals (TDS) to the first and second TTL, respectively. The TDC includes first and second sharing switch devices (SSD) respectively connected to the first and second TTL. The first and second SSD are connected to each other. The first TDS has a first voltage level during a first period, and the second TDS has a second voltage level different than the first voltage level during the first period. The TDC is configured to turn on the first and second SSD during a second period after the first period such that the first and second TDSs have a voltage level between the first voltage level and the second voltage level.

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.

Display apparatus including a touch driving circuit

A driving system for a vehicle includes: a communication apparatus; at least one processor; and a computer-readable medium having stored thereon instructions that, when executed by the at least one processor, cause the at least one processor to perform operations that include: receiving, through the communication apparatus, Advanced Driver Assistance system (ADAS) information that is based on a location of the vehicle; determining, based on the ADAS information, whether to use at least one ADAS for the vehicle; and based on a determination of whether to use the at least one ADAS for the vehicle, providing a control signal for controlling at least one of a steering operation, a brake operation, or an acceleration operation of the vehicle.
