Abstract
A floating touch display apparatus is provided. The apparatus comprises a display panel and a touch identifying unit. The display panel comprises: a plurality of pixels, each pixel of the display panel including n sub-pixels, and the n sub-pixels respectively emitting light having wavelengths in a first to an n-th wavebands to display and image; a plurality of light-emitting units, each light-emitting unit being configured for emitting light having a wavelength in a (n+1)-th waveband, and wavelength ranges of the light in the first to the (n+1)-th wavebands being not coincide; a plurality of light-receiving units, each light-receiving unit being configured for receiving the light in the (n+1)-th waveband and generating a touch identifying signal. The touch identifying unit identifies a floating touch action according to the touch identifying signal generated by the light-receiving unit.
