Abstract
A floating touch display device and a floating touch method are provided. The floating touch display device includes a display layer, a protective cover, light emitting units, and light receiving units; the protective cover includes a first region and a second region surrounding the first region; the display layer is disposed under the first region; the light emitting units and the light receiving units are sequentially arranged under the second region. Each of the light emitting units corresponds to one light receiving unit. The floating touch is realized, by a light emitting unit transmitting an optical signal toward a direction above the protective cover and a corresponding light receiving unit of the light emitting unit that receives the optical signal reflected by a touch object above the protective cover. Such a design can extend a touch range of the floating touch and improve user experience.
