1. A driving control module for a double-layer panel, wherein the double-layer panel comprises a first panel and a second panel, the first panel is a touch display panel, the second panel is a display panel, and the driving control module comprises a control circuitry, wherein the control circuitry is electrically coupled to the first panel and the second panel, and configured to control a touch stage of the first panel to be arranged within a spacing stage of the second panel, the first panel is configured to perform touch detection in the touch stage, and the spacing stage comprises at least one of a scanning blank stage, a frame start time of an image display time period, and a frame end time of the image display time period;
wherein the spacing stage comprises the scanning blank stage, the scanning blank stage comprises an inter-frame blank time period, and the control circuitry is configured to control the first panel to perform the touch detection in the touch stage in an inter-frame blank time period of the first panel and control the inter-frame blank time period of the first panel to at least partially overlap the inter-frame blank time period of the second panel;
wherein the control circuitry is configured to control a refresh rate of the first panel to be the same as a refresh rate of the second panel, and control frame synchronization between the first panel and the second panel;
wherein the control circuitry is specifically configured to control a time interval between a scanning start time of the first panel and a scanning start time of the second panel to be less than or equal to a first error time, and the spacing stage comprises the frame start time of the image display time period or the frame end time of the image display time period.
