    Abstract: A curved grating structure, a display panel and the display device are provided. The curved grating structure includes multiple grating strips spaced from each other. Grating intervals between adjacent grating strips are successively decreased from a center point of the curved grating structure to a terminal of the curved grating structure. The grating interval between two adjacent grating strips is a distance in a first direction between center points of the two adjacent grating strips, and the first direction is a direction perpendicular to a normal vector of the curved grating structure passing through a center point of the curved grating structure.

    Abstract: Disclosed is a detection target positioning method and device. The method comprises: acquiring an original image and pre-processing the original image to obtain a gradation of each pixel in a target gradation image corresponding to a target region including a detection target; calculating first gradation sets corresponding to rows of pixels of the target gradation image and second gradation sets corresponding to columns of pixels of the target gradation image; and determining rows of two ends of the detection target in a column direction according to the first gradation sets, determining columns of two ends of the detection target in a row direction according to the second gradation sets, and determining a center of the detection target according to the row of two ends of the detection target in the column direction and the columns of two ends of the detection target in the row direction.

    Abstract: The present disclosure relates to a touch panel controller, a control information acquisition method and a touch display device in the field of display technology. The touch panel controller includes at least two conductive members and a rotating component. The rotating component includes a supporting component and a mounting component connected to each other. The mounting component is configured to have the at least two conductive members mounted thereon. One end of the supporting component is configured to determine a placement surface that is in contact with a touch panel. A distance between each of the at least two conductive members and the placement surface is less than a sensing distance, and the sensing distance is a distance at which a capacitance change caused by the conductive member is detectable by the touch panel. In the present disclosure, a plurality of rotatable conductive members in the controller are used to input a multi-point touch operation such as rotation or multi-point sliding, which solves the problem in the related art that it is difficult for the stylus to accomplish multi-point touch operations and achieves an effect of performing a variety of multi-point touch operations through the controller.
