Display device, has power voltage adjustment circuit adjusting one of power voltage and gate voltage of power data to different reference level in response to predetermined power control signal

摘要

The device has a data control circuit (12) that divides voltage of power data for converting input digital video data into analog voltage data and applies the analog voltage data to a set of data lines (15). A power voltage control circuit (111) detects frequency of an input frame and generates a power control signal (CONT) that differs based on detected frame frequency. A power voltage adjustment circuit (17) adjusts one of power voltage and gate voltage of power data to a different reference level in response to a predetermined power control signal. An independent claim is also included for a method for controlling a display device.
