Abstract: A display apparatus includes a data driver and a light valve controller. The data driver is configured to continuously provide K display signals, all of which include a same set of image data, to a display panel. K is an integer greater than or equal to 2. The light valve controller is configured to provide a turn-off signal to a light valve whenever the data driver provides one of first T or odd-numbered display signals in the K display signals, and provide a turn-on signal to the light valve whenever the data driver provides one of last (K−T) or even-numbered display signals in the K display signals. T is an integer greater than 0 and less than K, and (K−T) refers to a difference between K and T.

Abstract: The embodiments of the present invention provide a parallax barrier panel, a display substrate, a display device, an electronic equipment and a display method. The parallax barrier panel includes a switchable array and a control module. The switchable array is used for forming a parallax barrier. The control module is used for adjusting the direction of the parallax barrier based on the interocular direction of an observer. By adjusting the direction of the parallax barrier based on the interocular direction of the observer, an ideal three-dimensional display effect can always be provided to the observer during three-dimensional display.
