Abstract: A touch sensor may include a substrate and may include electrode units, first demultiplexers, second demultiplexers, and driving pads all located on the substrate. The electrode units each may include a plurality of electrode groups, the electrode groups each including a plurality of touch electrodes. The first demultiplexers each may include a plurality of sub-demultiplexers and each may be electrically connected to a corresponding one of the electrode units. Each of the sub-demultiplexers of a first demultiplexer may be electrically connected to a corresponding one of the electrode groups of a corresponding electrode unit. The second demultiplexers may be connected between the first demultiplexers and the driving pads.

Abstract: A display device according to an embodiment of the present disclosure is provided. The display device comprises a light emitting diode, a first transistor connected between an initialization power source and an anode of the light emitting diode and having a gate electrode connected to an initialization line, and an initialization driver for supplying an initialization signal to the initialization line. The initialization driver supplies the initialization signal every frame when driven at a first frequency and supplies the initialization signal every set of two or more frames when driven at a second frequency different from the first frequency.

Abstract: A display device may include: a first pixel including first and second sub-pixels coupled to first and second data lines; a data driver which supplies data signals to first and second output lines; and a switch unit which distributes the data signals to the first and the second data lines. The first and the second sub-pixels are line-symmetrical with each other. Each of the first and the second sub-pixels may include: an OLED; a first transistor which controls a driving current flowing from a first power supply to a second power supply via the OLED, in response to a voltage supplied to a node connected thereto; emission control transistors which are turned on when an emission control signal is supplied; and a reference transistor which couples a shielding layer overlapping a corresponding data line to the first power supply when the emission control signal is supplied thereto.
