Abstract

The invention discloses a touch display module and electronic equipment, and relates to the technical field of optical fingerprint identification, for solving the problems that in the fingerprint identification process, a substrate of a touch substrate easily affects the polarization state of passing light, so that optical energy loss is generated when the light is emitted to a fingerprint identification receiving end through a polarizer and the success rate of fingerprint identification under a screen is reduced. The touch display module comprises a touch substrate located on the light emitting side of a display panel, wherein the base of the touch substrate has a preset phase difference, so as to enable the difference between the energy of the first light ray emitted by the display paneland the energy of the second light ray entering a fingerprint recognition module to be not larger than a threshold value, wherein the second light ray is a light ray which is irradiated to the fingerprint recognition module after the first light ray is reflected by an external object and then penetrates through the polarizing structure, the touch substrate and the display panel. The touch displaymodule provided by the invention is used for realizing a touch display function.
