  • Method and apparatus for controlling driving current of illumination source in a display system
    Patent number: 7317289
    Abstract: The present application describes a programmable current controller for regulating an operating driving current flowing through an illumination source. The driving current is regulated according to a digital reference corresponding to a predetermined operating current for the illumination source. The digital reference can be converted into a reference electrical parameter (current or voltage). The reference electrical parameter is compared with an operating electrical parameter (current or voltage) corresponding to the operating driving current of the illumination source. Based on the comparison, a driving bias current is generated, which is used to regulate the operating driving current of the illumination source.

  • DRIVING CIRCUITS
    Publication number: 20070035496
    Abstract: Driving circuits capable of outputting video data or OSD data selectively are used to serve as images on a display. The driving circuit which is integrated in a display panel comprises a selection unit that receives video data and on-screen-display (OSD) data and outputs the video data and the ODS data selectively according to a control signal, and a digital-to-analog conversion unit that converts the video data or the OSD data to an analog signal to drive a pixel array.
