  • Patent number: 7411581
    Abstract: A touch pad (101) includes transducers (201-204) for receiving acoustic signals resulting from touch events, such as the continuous movement of a fingertip across the surface (105) of the touch pad. The acoustic signals are acquired at different transducer locations in the surface. Signals from different transducers are combined, preferably in antiphase, to improve signal characteristics. The transducer signals are supplied to a stereo analogue to digital converter (407). Phase differences (706) are obtained and compared (703) with phase difference profiles (607) of known location, in order to identify the location of the touch event. An index (606) is used to identify candidate locations to reduce the amount of processing. Interpolation (705) is used to locate the touch event between profile locations.

  • Patent number: 7379073
    Abstract: A method of restoring RGB gray scale data for maintaining a sharpness of a screen and reducing a size of a memory is disclosed. The RGB gray scale data having M bits are truncated to generate a first RGB gray scale data having N bits, M being a positive integer and N being an integer less than M. RGB gray scale data information is generated based on a bit information of the first RGB gray scale data. A bit value of a MSB of the first RGB gray scale data is compared with a value of a dither table based on the RGB gray scale data information to generate a comparison value, when a bit value of at least one bit of the first RGB gray scale data is different from other bit values of the first RGB gray scale data. The first RGB gray scale data are compensated based on the RGB gray scale data information and the comparison value. Thus, the sharpness of a screen may be maintained and the size of the memory may be reduced.

  • Patent number: 7379079
    Abstract: An electro emission device (EED) operated by a driver for modulating the pulse width of a driving pulse according to a pulse width modulation (PWM) clock signal to control the brightness of images. The EED calculates a brightness level of image data indicating the brightness of the whole image for each unit image of a video signal. The image data is stored for each unit image of the video signal. The reference brightness level stored in the look-up table is compared with a calculated brightness level to determine a signal of the PWM clock signal condition. A PWM clock signal is generated according to the signal of the PWM clock signal condition to drive the display panel based on the PWM clock signal.
