Abstract: Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane- switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

Abstract: Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal.; The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.

Abstract: A touch sensor panel having co-planar single-layer touch sensors fabricated on a single side of a substrate is disclosed. The drive and sense lines can be fabricated as column-like patterns in a first orientation and patches in a second orientation, where each column-like pattern in the first orientation is connected to a separate metal trace in the border area of the touch sensor panel, and all patches in each of multiple rows in the second orientation are connected together using a separate metal trace in the border area of the touch sensor panel. The metal traces in the border areas can be formed on the same side of the substrate as the patches and columns, but separated from the patches and column-like patterns by a dielectric layer.

Abstract: A substantially transparent mutual-capacitance touch sensor panel is disclosed having sensors fabricated on a single side of a substrate for detecting multi-touch events. Substantially transparent row and column traces can be formed on the same side of the substrate, separated by a thin dielectric material, using diamond, rectangular, or hexagonal rows and columns. Dummy shapes of the same material as the row and column traces can be formed alongside the rows and columns to provide optical uniformity. The metal traces in the border areas used to route the rows to the short edge of the substrate can also be formed on the same side of the substrate as the rows and columns. The metal traces can allow both the rows and columns to be routed to the same short edge of the substrate so that a small flex circuit can be bonded to only one side of the substrate.

Abstract: Using multiple digital mixers in touch panels to perform spectrum analysis of noise and identify low noise stimulation frequencies and use of the multiple stimulation frequencies and phases to generate an image of touch is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch panel and can have multiple mixers. Each mixer in the sense channel utilizes a circuit generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases (e.g. positive and negative) of selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the multiple mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the selected frequencies in phase. The selected stimulation frequencies may be low noise frequencies. The demodulated signals from the multiple mixers can be used in calculations to determine an image of touch at each frequency. Also claimed is touch screen where image of touch is obtained during vertical blanking. Driver logic is claimed including a charge pump for converting low level supply voltage into higher level voltage and utilising the higher level voltage to generate reduced amplitude stimulation signals for driving a plurality of drive lines; a plurality of sense channels each including a charge amplifier for receiving a sense signal from a different sense line, wherein each charge amplifier in each sense channel includes a reduced feedback capacitance whose physical size is scaled down in accordance with a lower amount of charge injected into the sense lines by the reduced amplitude stimulation signals.
