Abstract: Disclosed is a display device that includes a display area having an appearance of a specific color in a non-driving state or displaying a specific screen by using PDLC to improve esthetic appearance as in a home appliance. The display device comprises a reflective dispersed layer arranged on a display panel, wherein the reflective dispersed layer includes a PDLC layer between a first substrate and a second substrate, and a transflective layer arranged between the PDLC layer and the second substrate to transmit light externally emitted from the display panel and reflect externally incident light.

Abstract: A display panel includes an edge area having a rounded shape and a flat inner area in which a plurality of touch electrodes are disposed. A plurality of driving lines applying a touch driving signal to the plurality of touch electrodes are disposed in the display panel. A touch circuit outputs the touch driving signal applied to the edge area at a voltage level higher than a voltage level of the touch driving signal applied to the inner area.

Abstract: A touch display device. A touch display panel includes a source multiplexer switching the transfer of source signals to data lines. In a low power wake-up gesture (LPWG) mode in which a touch input is only sensed in a state in which a display function is off to reduce power consumption, a source multiplexer control signal is provided to set the source multiplexer in an on state, in synchronization with a touch sensing section in which a touch driving signal is provided. This can discharge electric charges generated within the display panel, thereby preventing display defects due to the electric charges.
