Abstract: A texture image acquiring device, a display device and a collimator are disclosed. The texture image acquiring device includes a collimator and an image sensor. The collimator includes a lens array, a first diaphragm layer, and a second diaphragm layer. The lens array allows light rays to be converged and incident on the first diaphragm layer. The first diaphragm layer allows light rays incident on the first diaphragm layer to pass through and be incident on the second diaphragm layer, and restricts an angle of light rays capable of passing through the first diaphragm layer. The second diaphragm layer allows light rays incident on the second diaphragm layer to pass through, and restricts an angle of light rays capable of passing through the second diaphragm layer. The image sensor senses light rays incident on the image sensor for acquiring a texture image.

Abstract: An array substrate, display device and image display method. In this array substrate, among the sub-pixels two adjacent columns of sub-pixels are grouped together, and sub-pixels in different groups do not overlap each other; in each group, all of the sub-pixels are electrically connected with a same data line; each row of the sub-pixels corresponds to two gate lines, and in each row of the sub-pixels, two sub-pixels belonging to the same group are electrically connected with one of the two gate lines corresponding to this row of the sub-pixels respectively; thus, in the process of sequentially loading a gate scanning signal to each grid line within the display time of one frame, charging difference between rows of sub-pixels caused by the jump of voltage loaded on the data line may be reduced, whereby poor stripes present when a flat panel display is displaying a screen may be improved.
