A touch display device, a driving circuit, and a driving method according to embodiments of the disclosure can output an uplink signal having a first amplitude before receiving a downlink signal and output an uplink signal having a second amplitude higher than the first amplitude after receiving the downlink signal, thereby effectively mitigating the level of electromagnetic interference noise.

Touch display device, driving circuit, and driving method

A display device in one example includes a display unit, an outer roller configured to wind or unwind the display unit and including an inner circumferential surface having a spiral groove, an inner roller disposed in the outer roller and including an outer circumferential surface having a straight groove, a plurality of conductive balls disposed between the outer roller and the inner roller, and a roller connection unit interlinking rotations of the outer roller and the inner roller. The display unit can include a display panel and a back cover supporting a rear surface of the display panel. Further, the plurality of conductive balls can be configured to move along the spiral groove when the display unit is wound or unwound.

Display device including inner and outer rollers

A touch display device includes a display layer including a light emitting layer, a touch layer including a touch electrode, a metal shielding layer disposed between the light emitting layer and the touch electrode, a reference signal line electrically connected to the metal shielding layer, and a compensation circuit that supplies a reference signal through the reference signal line.
