The invention provides an infrared touch control method and device, relates to a touch control technology for display screens, and aims to realize floating touch control. The infrared touch control device comprises a display screen, wherein a plurality of infrared transmission modules and infrared receiving modules are arranged inside the display screen; the receiving spectrums of all the infrared receiving modules are the same as the transmission spectrums of all the infrared transmission modules; and a touch control identification module is further provided. The infrared transmission modules are used for transmitting infrared rays; the infrared receiving modules are used for receiving infrared rays reflected by a touch control object; the touch control identification module is used for converting the infrared rays received by each infrared receiving module into corresponding electric signals; and when an electric signal which is greater than or equal to a first threshold value, a determination indicating that the touch control object enters the sensing range of the display screen is made and a touch control signal is generated in order to make response to the operation of the touch control object on the display screen. The infrared touch control method and device are applied to the design and generation of an infrared touch control display screen.
