  • Patent number: 9773462
    Abstract: 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.

  • Patent number: 9672778
    Abstract: A method of driving a display panel includes steps of generating a plurality of load signals, of which at least one load signal has a different timing from the rest of the load signals, generating data voltages synchronized to low periods of the load signals and outputting the data voltages to data lines. Accordingly, the data voltages synchronized to each of the load signals can be outputted to each of the data lines. A color coordinate problem occurring when applying a RGBW type may be solved by setting a charging time of a white sub-pixel different from the rest of the sub-pixels. Thus, display quality of a display apparatus including the display panel may be improved.

  • Patent number: 9619020
    Abstract: A computer system can be controlled with non-contact inputs, such as eye-tracking devices. A visual indicator can be presented on a display to indicate the location where a computer function will take place (e.g., a common cursor). The visual indicator can be moved to a gaze target in response to continued detection of an action (e.g., touchpad touch) by a user for a predetermined period of time. A delay between the action and the movement of the visual indicator can allow a user time to “abort” movement of the visual indicator. Additionally, once the visual indicator has moved, the visual indicator can be controlled with additional precision as the user moves the gaze while continuing the action (e.g., continued holding of the touchpad).
