摘要： A touch sensor of multi-driving scheme includes a touch panel including input lines and output lines, the touch panel causes a change in mutual capacitance in response to touch. Processing circuitry generates transmission signals to the input lines as a result of an encoding operation on a first matrix having an inverse matrix, each of the transmission signals has a first polarity or a second polarity opposite in phase to the first polarity; outputs the transmission signals in an unbalanced period when the sum of phases of the transmission signals is greater than 0; receives receiving signals through the output lines; and decodes the receiving signals based on the first matrix, the receiving signals generated by the change in the mutual capacitance in response to the touch.

摘要： A display device, including: a touch screen panel including a touch panel and a display panel stacked under the touch panel; a touch driving circuit; and one or more rollers on which at least a portion of the touch screen panel is rolled. The touch panel may include receiving electrodes extending in a first axis direction and arranged in parallel in a second axis direction perpendicular to the first axis direction and driving electrodes extending in the second axis direction and arranged in parallel in the first axis direction. The display panel may include gate lines and source lines intersecting with the gate lines. The touch driving circuit may be configured to apply driving signals to the driving electrodes. The touch screen panel rolled on the one or more rollers may be unfolded as the one or more rollers slide in the first axis direction.

摘要： A touch analog front-end (AFE) for a touch sensitive screen may include a transmitter configured to charge a touch panel and a receiver configured to sense the touch panel. The receiver may include a charge-to-voltage (C2V) converter configured to convert a change of capacitance received from the touch panel into a voltage signal, a correlated double sampling (CDS) block configured to convert the voltage signal into a differential signal and to sample each of the positive and the negative signals of the differential signal, and an integrator configured to accumulate a difference between the sampled positive and negative signals.

摘要： Provided are a semiconductor device and a semiconductor system, which can increase immunity against noises through tertiary correlated double sampling (CDS). The semiconductor device includes an amplifier that receives noise and a driving signal, resets for each predetermined period of the driving signal and samples the noise to generate first sampled noise. The first sampled noise includes multiple noise differences each occurring between consecutive reset points. A sampler performs second sampling and third sampling on the first sampled noise and performs fourth sampling on the second and third sampled noises. The first sampled noise includes first to third noise differences, the second sampled noise is a difference between the first and second noise differences, the third sampled noise is a difference between the second and third noise differences, and the fourth sampled noise is a difference between the second and third sampled noises.
