Abstract: Dual power supply and energy recovery techniques are used in a capacitive touch panel that employs a concurrent drive scheme. A dual supply output buffer boosts a capacitor from an intermediate voltage level to a high voltage level. Energy recovery exchanges stored energy between a capacitor and an inductor. When both techniques are used together, power consumption of a capacitive touch panel drive circuit can be reduced dramatically, by as much as about 80%. Such high efficiency touch panels have wide application to ultra-thin touch screens, including those suitable for use in mobile devices and flexible displays.

Abstract: An input device can be capacitive coupled to earth ground and noise sources which can interfere with the ability of the input device to detect an input object. To mitigate the effects from these capacitive couplings, the input device drives a modulated capacitive sensing signal onto a plurality of sensor electrodes in parallel. The sensor electrodes are coupled to respective analog front ends (AFEs) which generate an output signal for each of the sensor electrodes. The input device combines the output signals for the sensor electrodes to generate a normalization value. For example, the output signals may be digital values which are summed by the input device to generate the normalization value. The input device then divides each of the output signals by the normalization value to result in a normalized signal corresponding to each of the sensor electrodes.

Abstract: A touch-panel liquid-crystal display device in one embodiment includes a metal line formed on a thin-film transistor array substrate, a gap column spacer and a push column spacer on a portion of a color filter array substrate that corresponds to an intersection of gate and data lines of the thin-film transistor array substrate, and a liquid-crystal layer between the thin-film transistor array substrate and the color filter array substrate. The gap column spacer and the push column spacer have the same height and the gap column spacer is located on the metal line, which facilitates an exposure process, minimizes generation of foreign substances when printing an alignment layer, and enables adjustment of the optimum amount of liquid crystals when liquid-crystal dotting is performed. The push column spacer is located on the metal line when the device can be pushed or bent by external force, and thus increases panel rigidity.

Abstract: Embodiments herein describe input devices that include receivers for sampling capacitive sensing signals. In one embodiment, the receivers perform continuous demodulation where the sampling of the capacitive sensing signal is not synchronized with the modulated signal applied to the sensor. To calibrate, the receiver generates first and second measurements of the capacitive sensing signal when driving a modulated signal onto one or more sensor electrodes during two respective time periods. However, the phase of at least one signal is controlled during the time periods so that the first and second measurements have a phase difference of ninety degrees. Using the first and second measurements, the receiver can determine a phase offset between the capacitive sensing signal and the modulated signal which can be used to alter future measurements so that at least some of these measurements are captured when the capacitive sensing signal is at a peak amplitude.
