摘要： A semiconductor device includes a delay compensation circuit and a bias control circuit. The delay compensation circuit includes a variable delay circuit configured to generate an output signal by delaying an input signal and configured to compensate, according to a first bias control signal, for delay fluctuation caused by fluctuation of a power supply voltage between a first power source and a second power source. The bias control circuit is configured to generate the first bias control signal to compensate for the delay fluctuation.

摘要： 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.
