摘要： A capacitive multi-touch system includes a touch sensor pane, a front-end circuit, and a digital signal processor. The touch sensor panel generates a capacitance signal corresponding to a touch input. The front-end circuit converts the capacitance signal to a sensing channel signal. The digital signal processor receives a common voltage (VCOM) from a display device, calculates a noise interval of two neighboring noise peaks of the common voltage, and performs a noise filtering operation on the sensing channel signal using a noise filter path. The noise filter path is selected from a plurality of noise filter paths based on the noise interval.

摘要： Embodiments relate to a gate driving integrated circuit and an operating method thereof operating in a time-division method divided into a display period and a touch period. The gate driving integrated circuit includes a charging circuit, a gate control circuit, and a discharging circuit. The charging circuit charges a memory element. The discharging circuit discharges the memory element. The gate control circuit outputs a gate-on voltage to a gate line based on the charged memory element in during display period. The gate control circuit electrically disconnects the memory element from the gate control circuit during the touch period.

摘要： A touch panel comprises multiple first sensing electrodes constituting multiple rows, wherein the first sensing electrodes in each of the rows are electrically connected to each other, multiple second sensing electrodes constituting multiple columns crossing the rows, wherein the second sensing electrodes in each of the columns are electrically connected to each other, and multiple conductive patterns disposed between the first and second sensing electrodes. Each of the first and second sensing electrodes comprises multiple protrusions protruding outward from a corresponding boundary and multiple concave portions extending inward between the protrusions in a plan view. Pairs of protrusions extending from opposite sides of each of the first and second sensing electrodes are disposed opposite each other and are symmetrical to each other.
