An multi-touch detection system () separately determines each of the coordinates of multiple touches and is able to correctly pair the coordinates, the touch panel includes multiple (e.g., two or four) separate sections () to detect touches in different areas. The system () is able to operate at high refresh rates allowing speed sensitive applications to be supported.

Multi-touch detection panel with disambiguation of touch coordinates

A method and apparatus are provided for detecting activation of a touch panel. The method includes the steps of providing an N by M touch panel including a matrix of N rows of touch elements along a first axis and M columns of touch elements along a second axis, providing N optical beams where a characteristic of each beam of the N beams is different than the corresponding characteristic of any other of the N optical beams, where the summation of a characteristic any first group of the N optical beams is different than the summation the corresponding characteristic of any other N beams and where each respective beam of the N optical beams corresponds to an input of each of the N rows; and summing the characteristic from an output of each of the N rows.

Waveguard touch panel

A method and apparatus are provided for correcting burn-in in a flat screen display. The method includes the steps of determining a maximum cumulative luminance of each pixel () within the display () based upon a usage of the pixel, providing a modulation map () of the display () from the maximum cumulative luminance of each pixel () within the display (), transforming the modulation map () based upon the maximum cumulative luminance of groups of adjacent pixels to provide a modulation index for each pixel location of the map (), comparing the modulation indexes with a set of threshold values and adjusting a luminosity of associated pixels () of the display () when the modulation index exceeds the threshold.

Method of correcting emissive display burn-in

Disclosed is reflective morphable display with multi-layered depth viewing, low power consumption and few components and a method of activating various features thereof. The disclosed display includes a bi-stable reflective cholesteric liquid display crystal (ChLCD) layered in combination with a display device such as an LCD and a quarter lambda (&#x3bb;/4) retardation film layer. Linearly polarized light emerging from the front surface of a display device is circularly polarized by the &#x3bb;/4 layer before entering the ChLCD layer. In its reflective state, the ChLCD layer receiving a portion of the ambient light having the same handedness of the ChLCD is reflected in a mirror-like manner. Also in its reflective state, when it receives light that is circularly polarized by the &#x3bb;/4 retardation film layer, the ChLCD layer acts as a shutter. A display device with depth viewing is provided as the ChLCD layer pixelated so it is configured to display font and/or other indicia.
