  • Patent number: 7907123
    Abstract: One exemplary method embodiment herein can run an operating system on a processor and executes one or more applications on the operating system (sometimes simultaneously) that causes different input requests to be dynamically displayed on a visual display. If more than one application is being executed at a time, only one currently selected application can be available for user input at a time. These input requests can dynamically change depending upon the current state of the currently selected application. The method controls the keys with the operating system to dynamically illuminate only valid keys that correspond to input requests of the currently selected application being currently displayed on the visual display.

  • Patent number: 7898519
    Abstract: A backlight display has improved display characteristics. An image is displayed on the display which includes a liquid crystal material with a light valve. The display receives an image signal, modifies the light valve with an overdrive for a first region of the image based upon the timing of the illumination of the region, and modifies the light valve with an overdrive for a second region of the image based upon the timing of the illumination of the second region.

  • Patent number: 7875814
    Abstract: An electromagnetic digitizer having a sensor segment that includes a generally longitudinal network of conductive lines. Two or more conductive lines are coupled in parallel. To enhance sensitivity, the adjacent lines are interconnected along the longitudinal structure, using interconnections in the form of short lines, oriented at an angle. The sensor segments may be miniaturized, to facilitate integration into a display module using semiconductor fabrication processes. Various sensor array structures may be implemented using the sensor segment structures. The sensor array may include longitudinal sensor segments arranged in a parallel array. To further enhancing sensitivity of the sensor array, additional lines may be provided between adjacent longitudinal sensor segments. The sensor array may also include half loop (or U-shaped) sensor segments arranged in an overlapping parallel array, or full loop sensor segments arranged in an overlapping parallel array.

  • Patent number: 7852309
    Abstract: Provided is a scan driver that supplies a scan signal to an organic light emitting display device (OLED). The scan driver includes transistors of the same conductivity type. To generate individual scan signals, the scan driver includes samplers, each of which samples an input signal in synchronization with a clock signal or an inverted clock signal; and an OR gate and a NAND gate, each of which performs a logical operation on output signals of adjacent samplers and generates a scan signal. The samplers, the OR gate and the NOR gate include transistors of the same conductivity type.

  • Patent number: 7737959
    Abstract: A detection system. The detection system includes a substrate, a laser, and a sensor array. The substrate includes a first surface, a second surface conceptually divided into multiple areas, and a third surface. The laser is configured to emit electromagnetic radiation into the substrate and incident subsequently onto second surface areas. The sensor array is configured to capture electromagnetic radiation reflected from the second surface. If a first dielectric, having first dielectric constant, is in contact with some areas, electromagnetic radiation incident thereon experiences total internal reflection and if a second dielectric having second dielectric constant is in contact with other areas, some of the electromagnetic radiation incident thereon is reflected back into the substrate by the second dielectric.

  • Patent number: 7692607
    Abstract: A method for adjusting an image on the basis of characteristics of a display system is provided. The image includes M horizontal lines. Each of the M horizontal lines respectively includes N pixels. Each pixel has an original gray level. A look-up table previously stores a plurality of conversion coefficients related to the characteristics of the display system. The method first calculates an ith loading according to the N original gray levels of the N pixels in the ith horizontal line. Based on the ith loading, an ith conversion coefficient corresponding to the ith loading is selected from the plurality of conversion coefficients in the look-up table. The method respectively multiplies the N original gray levels of the N pixels in the ith horizontal line by the ith conversion coefficient to generate N new gray levels for the N pixels in the ith horizontal line, whereby the image is adjusted.
