  • Patent number: 7623123
    Abstract: The present invention relates to an organic electroluminescent device that can reduce power consumption and is appropriate for low gray scale images. The organic electroluminescent device includes a controller and a data driver. The controller compares first digital video data inputted from the outside with a reference value, and adds first dummy bit data or second dummy bit data to the first digital video data in accordance with result of the comparison, thereby generating second digital video data. The data driver generates current corresponding to the first digital video data by using a method corresponding to the dummy bit data included in the generated second digital video data. The organic electroluminescent device uses a PAM method or a PWM method to drive the display based on the gray scale level of the digital video data. For low level gray scale images, the PWM method is used, which ensures a good quality image.
