  • Patent number: 8188959
    Abstract: An exemplary liquid crystal display includes a frame buffer (41), a frame rate conversion circuit (42), a data divider (43), and a data driver (44). The frame buffer is configured for doubling a frame rate of inputted signals. The frame rate conversion circuit is configured for reducing a bit number of signals. The frame rate conversion circuit includes a first and a second look up table. The first look up table converts a gray level of one of the sub-frames into a higher gray level corresponding to signals with the lower bit number. The second look up table is configured for converting a gray level of the other sub-frame into a lower gray level corresponding to signals with the lower bit number. The data divider is configured for transmitting the signals to the data driver in several buses. The data driver drives the liquid crystal display to display images.

  • Patent number: 8068092
    Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are provided by logic structures resident on the device. The device enables editing during text entry and provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants without changing the position of the user's hands on the device.
