  • Patent number: 7999491
    Abstract: For providing a compact high-precision lighting control means to drive an LED lighting module, a lighting control integrated circuit is set forth to perform an accurate lighting control. At least one nonvolatile memory is embedded in the lighting control integrated circuit for storing a plurality of lookup tables. One lookup table provides related data for setting the driving currents of the LED lighting module based on spacing or pitch of LED disposition of the LED lighting module. Another lookup table provides related data to recover uniformity for different LED damage situations of the LED lighting module. The other lookup tables are applied to perform compensation processes on the driving currents concerning temperature variation, ambient light intensity, aging degradation, and power-on time. In addition, a signal processing unit, a pulse-width-modulation signal generating module, and a driving module are incorporated in the lighting control integrated circuit for signal processing and current driving.

  • Patent number: 7864074
    Abstract: A data driver used in a current-driving display device for receiving a digital signal and for outputting a gray-scaled current signal to a data line. The data driver includes a digital-to-analog current converter for transforming the digital signal into an analog current signal, a current-copying/reproducing module, and a control circuit. The current-copying/reproducing module is used to store a predetermined voltage for conducting the analog current signal in a transforming/storing status and to conduct a reproducing current signal to the data line in a reproducing/sustaining status. The control circuit is electrically connected between the digital-to-analog current converter and the current-copying/reproducing module for providing a switch between the transforming/storing status and the reproducing/sustaining status. The reproducing current signal is the gray-scaled current signal and is almost equivalent to the analog current signal.
