Patent ID: 11798513

Abstract:
Provided are a liquid crystal display device and a method for driving the same. The liquid crystal display device includes: a display panel; a gate driver; a data driver; and a timing controller configured to control operations of the gate driver and the data driver, and the timing controller configured to output a data signal, an internal clock signal, and a polarity control signal to the data driver based on image data, wherein the data driver is configured to invert polarity of a data voltage every predetermined, or alternatively, desired rows based on the polarity control signal, and in a plurality of adjacent pixel rows loaded with data voltages of the same polarity, an on-width of the internal clock signal of a first pixel row is greater than that of the internal clock signals of other pixel rows; and wherein when an original grayscale value of a target pixel row in the other pixel rows is different from the original grayscale value of a previous pixel row in the other pixel rows, the timing controller is configured to automatically adjust the grayscale value of the target pixel row, and output the adjusted grayscale value as the data signal of the target pixel row.
