An optical touch display device includes a display screen capable of emitting an invisible light, at least one image acquisition module, and a processing module. The image acquisition module is arranged at a peripheral edge of the display screen for acquiring an invisible light image on or above a surface of the display screen. The processing module calculates a spatial position of an object according to a position of the object in the invisible light image acquired by the image acquisition module. With these arrangements, the optical touch display device can have an effectively reduced thickness and the spatial position of the object can be determined in increased accuracy. Further, the processing module can determine a user's gesture according to the acquired invisible light image. A method for implementing optical touch display is also disclosed.
