Abstract: An electronic device includes a pressure providing part, a fluid, and a tactile sensation providing layer. The pressure providing part generates an initial pressure by an electrical signal. The fluid generates a fluidic pressure by the initial pressure in each of active regions partitioned from each other. The tactile sensation providing layer is configured to protrude by the fluidic pressure. The pressure providing layer may include piezoelectric elements mechanically modified by the electrical signal.

Abstract: A display apparatus includes a display panel and a driving circuit. The display panel includes pixels. Each of the pixels is connected to one of gate lines and one of data lines. The driving circuit drives the gate lines and the data lines to display an image on the display panel. The driving circuit alternately provides a first polarity data driving signal and a second polarity data driving signal to each of the plurality of data lines. During an asymmetrical mode, the first polarity data driving signal is provided to first data lines of the data lines during a first frame period before a blank period begins, and the second polarity data driving signal is provided to the first data lines during a second frame period after the blank period ends. The second frame period excludes the blank period.
