20090256810 | TOUCH SCREEN DISPLAY - A device may include a number of diodes and control logic. The control logic may be configured to forward bias a first one of the diodes for a first duration of time corresponding to a frame, forward bias a second one of the diodes for a first portion of the frame, and reverse bias the second diode for a second portion of the frame. The second diode functions as an input or touch detector during the second portion of the frame. | 10-15-2009 |
20090256811 | OPTICAL TOUCH SCREEN - A device may include a position sensitive detector that is configured to generate a value corresponding to a location associated with a shadow or absence of light on an upper surface of the position sensitive detector. The device may also include logic configured to receive the value, determine that a contact occurred on the display based on the value and determine a location of the contact based on the value. | 10-15-2009 |
20100084202 | ERGONOMIC STYLUS PEN AND RESERVOIR THEREFOR - The present invention provides a stylus member and a corresponding portable communication device. The stylus member comprises at least one electro-active polymer (EAP) unit that is adapted to change in size so as to enable the portable communication device to receive the stylus member in a housing provided therefor. Means for locking the stylus member in the housing as well as means for releasing the stylus member are also provided in the portable communication device. By providing at least one EAP unit in the stylus member, it may adopt an ergonomic shape facilitating the usage of the stylus pen, for instance when activating a pressure-sensitive screen or display of a portable communication device. This invention may provide an ergonomic stylus pen that can be ejected from a portable communication device upon detecting user input, such as detecting pressing of a button. | 04-08-2010 |
