The present invention provides a liquid crystal display device capable of suppressing a decrease in display quality when pause drive is performed in an alternating-voltage drive mode, as well as a method for driving the same. In a first drive frame, overshoot drive is performed using correction values provided by an LUT to apply overshoot voltages whose absolute values are higher than absolute values of signal voltages to data signal lines. Subsequently, in a second drive frame, normal drive is performed to write signal voltages of the same polarity as the overshoot drive voltages to the data signal lines. Thereafter, a pause period in which an image written by normal drive is displayed continues until the start of a drive period in the next pause drive period. As a result, a decrease in luminance immediately after the signal voltages are written during the second drive frame is suppressed significantly, so that the viewer barely recognizes flicker.

Provided are a liquid crystal display device and a drive method thereof, capable of promptly making an afterimage, which is visually recognized during pause drive, visually unrecognizable while suppressing power consumption. When updated image data is transmitted, a first refresh is performed by used of this image data, and a refresh pauses based on Ref_int just in the next two-frame period. Then, the second and third refreshes are consecutively performed, and a refresh pause is repeated until the next updated image data is transmitted. In this case, since a refresh can be performed three times in a short period after reception of the updated image data, it is possible to make liquid crystal molecules oriented in a direction corresponding to an applied voltage in a short time and make an afterimage visually unrecognizable.

A content item to be displayed via a display of an electronic device may be associated with a first set of grey values or a set of color values. The electronic device may generate, maintain, or at least have access to one or more mappings that map the set of color values and/or the first set of grey values to a second set of grey values. Based on the one or more mappings, the electronic device may convert a color value of the set of color values or a first grey value of the first set of grey values to a second grey value of the second set of grey values. The content item may then be displayed utilizing the second grey value.

Disclosed is a method for driving a liquid crystal panel, which includes: when a greyscale value of the liquid crystal panel is smaller than a first grey level, a first driving voltage that is a normal driving voltage corresponding to the greyscale value is applied to drive the data lines; and when the greyscale value of the liquid crystal panel is greater than the first grey level and smaller than or equal to a maximum grey level, driving of the data lines includes a first phase and a second phase, the first phase being in front of the second phase, the first phase using a second driving voltage smaller than or equal to the first driving voltage to drive the liquid crystal panel, the second phase using a third driving voltage that is a normal driving voltage corresponding to the greyscale value to drive the liquid crystal panel.

A display driving method includes: determining, by a timing controller, an actual grayscale value of a sub-pixel image in an X-th row and a Y-th column according to a preset grayscale value of a sub-pixel image in an (X−1)-th row and the Y-th column and a preset grayscale value of the sub-pixel image in the X-th row and the Y-th column of an image frame to be displayed. The image frame to be displayed includes J rows and Q columns of sub-pixel images. X is greater than or equal to 2, and is less than or equal to J. Y is greater than or equal to 1, and is less than or equal to Q, and X, Y, J, and Q are all integers.

Grayscale values for previous and current frames are different, and therefore, an overshoot voltage, which has a higher absolute value than a signal voltage, are applied to a data signal line. Next, in a second drive frame, normal drive is performed, so that a signal voltage of the same polarity as the overshoot voltage is written to the data signal line. Moreover, in a first drive frame of a third pause drive period, the grayscale values for the previous and current frames are equal, and also greater than or equal to a boundary value, and therefore, undershoot drive is performed. An undershoot voltage, which has a lower absolute value than a signal voltage, is applied to the data signal line. Next, in a second drive frame, normal drive is performed, so that a signal voltage of the same polarity as the undershoot voltage is written to the data signal line.
