The invention discloses a terminal display module and a mobile terminal. The terminal display module comprises a display panel and a three-dimensional imaging module, the vertical projection of the three-dimensional imaging module on the plane where the display panel is located is located in the auxiliary display area of the display panel. The three-dimensional imaging module comprises a transmitting module and a receiving module, the transmitting module comprises a structured light source and a floodlight source, the structured light source and the floodlight source both utilize HCG-VCSEL as light sources and emit linearly polarized light with the same polarization direction, and the receiving module is used for receiving light beams penetrating through a linearly polarized layer and imaging; the terminal display module further comprises a linear polarization layer located on the light incident path of the receiving module, and the direction of the light transmitting axis of the linear polarization layer is consistent with the polarization direction of linearly polarized light emitted by the HCG-VCSEL. The problem that three-dimensional structured light imaging displayed by an existing terminal is prone to being affected by external environment light and the transmittance of a display panel, and consequently the imaging quality is poor is solved, and the three-dimensional structured light imaging quality can be improved.
Description
technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a terminal display module and a mobile terminal. Background technique [0002] At present, mobile terminals have entered the era of full screen. In order to hide related devices such as structured light modules, various forms of display screens such as notch screens, water drop screens, and hole-digging screens have been born. However, these solutions affect the aesthetics and lead to a low screen ratio, which is not the final perfect full-screen form, and the under-screen structured light technology is the best solution to achieve a true full-screen form. [0003] The three-dimensional imaging module in the current under-screen structured light technology generally includes three parts: an infrared flood light source module, an infrared receiving module, and a structured light projection module, and the infrared flood light source module and the structured light...
