Abstract: Sunlight can damage a conventional touch screen display and cause the display to be quite difficult to read. Furthermore, conventional touch screen displays are easily damaged, and, once damaged, the entire touch screen is replaced. To address these concerns, a touch panel includes anti-reflective coatings on the surfaces of the top plate and the base plate that are open to the air. These coatings substantially reduce reflections and make the touch screen easier to read in direct sunlight. In particular, the anti-reflective coating used on the upper surface of the base plate is dielectric in nature to reduce reflectivity even further. This dielectric coating includes openings to an underlying conductive layer so that an electrical contact is made when a user deflects the top plate into the base plate. Also, the top plate may be detachably coupled to the base plate, advantageously by double stick adhesive tape, so that only the top plate is replaced when damaged.

Abstract: The present invention intends to provide a display position control apparatus which can prevent a position control signal to control a display position of an image from being unstable and can display the image with high image quality.

When it is detected that the phase relation is in the mismatch state, a display position control signal is generated on the basis of the vertical sync signal and the delay signal. When it is not detected that the phase relation is in the mismatch state, the display position control signal is generated on the basis of the vertical sync signal and the horizontal sync signal.

The graphical indicator has target value indicia that represents a target value of the parameter, and measured value indicia that represents a measured value of the parameter. A change in a measured value of the parameter relative to the target value is represented by a first corresponding amount of movement of the measured value indicia relative to the target value indicia when the measured value is within a first span of parameter values, and a second, different corresponding amount of movement of the measured value indicia relative to the target value indicia when the measured value is within a second span of parameter values. The graphical indicator provides increased sensitivity to changes in the measured value of the parameter as the measured value becomes closer to the target value of the parameter.

Abstract: One embodiment of the present invention provides a system that selectively magnifies a region within a computer display without obscuring proximate regions in the computer display. The system operates by receiving positioning information from a user of a computer system, wherein the positioning information determines a position of a magnifier within the computer display.

The system then displays the target region within the magnifier in magnified form, and displays the proximate regions within the magnifier in reduced and/or partially magnified form, so that features within the proximate regions are visible within the magnifier and are not obscured by the magnifier. The system also displays regions within the computer display not covered by the magnifier in unmodified form.

Abstract: A line inverse driving method is performed by outputting voltages for gradation display in mutually reverse polarities with respect to pixels adjacent in a data signal line direction. A separation switch is provided between an output stage of a data driver and a data signal line to separate them.

With this structure, respective charges in adjacent pixel capacitors are neutralized, and it is therefore possible to reduce a power consumption. Further, since a short-circuit can be performed at short distance, the problem of dull waveform can be suppressed, thereby realizing an image display device suited for a large screen.
