Abstract: Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing. compliant, and flexible multi-touch surface. The surface consists of compressible cushion, dielectric, electrode, and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize signal-to-noise ratio and to reduce wiring complexity. Such distributed transduction circuitry is economical for large surfaces when implemented with thin-film transistor techniques. Scanning and signal offset removal on an electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contact and extracts shape, position and surface proximity features for each group.

The IC includes a DC-DC converter for controlling an external DC voltage to a desired DC voltage through a timing control signal. A power peripheral unit is provided outside the IC, which controls an input voltage and an output voltage of the DC-DC converter and stabilizes the DC-DC converter. The DC-DC converter generates a desired DC voltage using the external input voltage according to a voltage control signal subject to the timing control signal. The generated DC voltage is provided to a data processor and a scan processor inside the IC. It is possible to control the DC voltage inside the IC using the DC-DC converter controlled by the timing control signal, and most parts of a power portion can be integrated inside the IC.

Abstract: Imaging systems that use a spatial light modulator (SLM), such as maskless lithography systems using a digital micromirror device (DMD), suffer from low throughput at high resolution because of the increase in the number of pixels to be imaged. A possible solution to this problem is provided by using multiple SLMs. However, packaging multiple SLMs on a suitable base is inefficient because, in an SLM, surrounding the active region, a large inactive region is required for the chip kerf and the connector fan-in; these inactive regions thus prevent close packing of the SLMs. This invention enables close packing of a large number of SLMs by arranging them in twin planes, such that the kerf and fan-in regions overlap substantially.

Then, a voltage applied to the second display electrode lines is gradually increased up to a second voltage higher than the first voltage while the voltage applied to the first display electrode lines is gradually increased up to a third voltage lower than the first voltage. The voltage applied to the first display electrode lines is maintained at the first voltage while the voltage applied to the second display electrode lines is gradually decreased down to a fourth voltage lower than the third voltage.

Abstract: Disclosed is a method of treatment for preventing the occurrence of image sticking and recovering from image sticking in a ferroelectric liquid crystal device. By applying a low-frequency AC voltage to the ferroelectric liquid crystal device, multiple domains are formed in a pixel, domain boundaries are caused to flow, and fine segmentation of domain regions are induced.

The low-frequency AC voltage is applied to the liquid crystal device immediately before stopping liquid crystal driving or immediately after starting liquid crystal driving. Further, the low-frequency AC voltage is applied when the occurrence of image sticking in the liquid crystal device is detected.
