Display module, control method thereof and display device

The embodiment of the invention provides a display module, a control method thereof and a display device. The display module comprises a time schedule controller and a display panel; the time schedule controller is used for determining a first feature table based on a plurality of pre-stored feature tables when the display picture is a common picture, and outputting gamma data in the first feature table; when the display picture is a motion picture, determining a picture motion state based on two pre-stored adjacent frames of images, determining a second feature table based on the picture motion state and a plurality of pre-stored feature tables, and outputting gamma data in the second feature table, the transmittance of the display panel corresponding to the first feature table is greater than that of the display panel corresponding to the second feature table; by adopting the embodiment of the invention, the transmittance of the display panel can be reduced, so that the liquid crystal response time can be s
