Abstract: The present disclosure relates to a system for measuring a naked-eye stereoscopic image, a method and apparatus for processing an image and a display device. The system includes: a naked-eye stereoscopic display device, configured to display preset images in sequence; an image acquisition device, configured to obtain monochromatic images by capturing display contents of the naked-eye stereoscopic display device, and send the monochromatic images to a processor; and a processor, configured to acquire at least one preset crosstalk amount to each stereoscopic pixel of the naked-eye stereoscopic display device from each view point according to the monochromatic images, where each of the at least one preset crosstalk amount represents a proportion coefficient that measures how much a view from another view point affects a color value of a view from a target view point.

Abstract: A method for clock calibration is provided. In the technical solution according to the present disclosure, a target driving chip includes a plurality of clock calibration circuits, wherein each of the clock calibration circuits is configured with one clock frequency. Prior to sending a clock calibration signal, a controller sends a reference clock frequency to a driving chip over a configuration instruction, such that the driving chip determines a target clock calibration circuit for clock calibration based on the configuration instruction.

Abstract: A gate drive circuit and a display panel are provided. The gate drive circuit controls, by adding a control module, the potential at a key node of an output module in a touch-control phase, that is, outputting a low-level signal of a signal switching end to a first node of the output module of the current-stage shift register in the touch-control phase, so as to stabilise the potential of the key node, i.e. the first node in the touch-control phase, thereby avoiding the case where the potential at the key node is in a floating state and thus is capacitively coupled and deviates from a stable potential; and a transition to a display stage before the touch-control state ends is made, and a high-level signal of the signal switching end is output to the first node, so as to pull up the potential at the first node.

Abstract: The disclosure provides a timing control method and a timing control circuit for a display panel, a driving device, and a display device. The method includes: in respective display periods, supplying a data enable signal to a source driving circuit. The source driving circuit supplies a data signal to a plurality of sub-display regions under the control of the data enable signal. The data enable signal is switched between an active level and an inactive level, and the active levels of the data enable signal are in one-to-one correspondence with the plurality of sub-display regions of the display panel. The farther one of the plurality of sub-display regions from the source driving circuit, the longer time period, at an active level, of the data enable signal for controlling the source driving circuit to provide the data signal to at least one row of pixels in the sub-display region is.
