Abstract: A touch display device is disclosed that divides an active area into a reference touch area and a non-reference touch area and independently drives touch electrode lines positioned in the reference touch area and touch electrode lines positioned in the non-reference touch area. Touch sensing performance is enhanced while preventing or reducing signal distortion due to a difference in unit touch sensors in the reference touch area and the non-reference touch area.

Abstract: The present disclosure is directed to a touch display device that is capable of reducing a load of a touch sensor structure disposed in a display panel and improving the accuracy of touch sensing capabilities of the touch display device. In one aspect, touch electrode lines disposed on an active area are disposed to be separated into a plurality of sub-areas. A number of touch routing lines connected to the touch electrode lines are disposed on the active area, thus a touch sensor structure with a reduced load can be provided while minimizing an increase of a non-active area due to an arrangement of the touch routing lines.

Abstract: A power supply and a method of driving the same. A converter receives an input voltage from a battery and outputs a first voltage through an output terminal, such that a ground voltage of the output terminal changes. A pulse width modulation (PWM) controller controls the converter to adjust the voltage level of the first voltage. The ground voltage is applied to the converter as a direct current (DC) voltage during a first time and as a pulse wave having a predetermined amplitude during a second time. The PWM controller controls the first voltage to have different voltage levels during the first time and the second time.

Abstract: A display device can include a display panel including multiple pixels each of which includes multiple sub-pixels. The display device can further include multiple data lines respectively connected to the multiple sub-pixels, multiple gate lines respectively connected to the multiple pixels, and N multiplexers (MUX) (N is a natural number larger than 1) disposed at input terminals of the multiple data lines. In one horizontal (H) period, a length of a turn-on period of a first MUX can be different from that of a turn-on period of an Nth MUX, where the one H period is a period in which a scan signal is supplied through one gate line.
