Abstract: A display panel driving apparatus includes an image pattern analyzing part, a clock signal generating part and a data driving part. The image pattern analyzing part is configured to analyze an image pattern of an image data. The clock signal generating part is configured to generating a clock signal having a different pulse width according to the image pattern of an image data. The data driving part is configured to drive a data line of a display panel in response to the clock signal. Thus, power consumption and heating of the data driving part may be decreased.

Abstract: A display apparatus includes pixels, gate lines and data lines, a gate driver driving the gate lines, a data driver which drives the data lines, and a timing controller which controls the gate and data drivers and provides digital image signals to the data driver. The data driver includes a digital-to-analog converter which receives first and second gamma voltages and converting the digital image signals to analog image signals and an output buffer which outputs the analog image signals to the data lines. The digital-to-analog converter includes a resistor string which receives the first and second gamma voltages and generates gamma voltages, a look-up table which stores selection signals, a first decoder which selects the gamma voltages and outputs the selected gamma voltages as gamma reference voltages, and a second decoder which converts the digital image signals to the analog image signals based on the gamma reference voltages.

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.
