  • Publication number: 20150084944
    Abstract: A display device includes a display panel and a driving voltage generator. The driving voltage generator generates a first quarter power voltage and a second quarter power voltage. The first quarter power voltage has a level between a power voltage and a half power voltage. The second quarter power voltage has a level between the half power voltage and a ground voltage. A data driver alternately outputs the first quarter power voltage or the second quarter power voltage and a data voltage to the data line. A signal controller controls the driving voltage generator and the data driver. The signal controller includes a pattern recognition unit determining an image pattern of an image based on an input image signal. The signal controller controls the driving voltage generator to adjust the levels of the first quarter power voltage and the second quarter power voltage, based on the determined image pattern.

  • Publication number: 20140347404
    Abstract: A controller for a display panel includes a detector, a timing controller, and a voltage generator. The detector detects a predetermined pattern in an image signal. The timing controller generates a control signal based on detection of the pattern. The voltage generator changes at least one driving voltage for a display panel from a first level to a second level based on the control signal. The predetermined pattern may correspond to at least one region having a predetermined arrangement of at least first and second gray scale values of pixels in an image corresponding to the image signal.
