The inventor has found that the conventional depth camera module uses a Vertical Cavity Surface Emitting Laser (VCSEL) as a light source, but since the output light power of the VCSEL Laser is low, when the transmittance of the display substrate is low, the light power of the Laser passing through a light-transmitting area is low, and an effective depth image cannot be obtained, it is necessary to provide a non-display area, i.e., liu Haiou, on the top of the display substrate, and to dig a hole in the non-display area to mount the VCSEL Laser.

And the floodlight projector is used for projecting floodlight to the object to be shot according to a preset light intensity threshold value so as to illuminate.
According to the display device and the electronic equipment with the 3D camera module, the depth camera module is arranged on the backlight side of the black matrix area of the display substrate, so that a non-display area such as a sea area does not need to be arranged at the top of the display device for installing the depth camera module, and the attractiveness and the comprehensive screen experience of the display device cannot be influenced.

The laser module adopts a vertical cavity surface emitting laser, an edge emitting laser and a semiconductor laser.
The light-emitting side of the display substrate is a side capable of displaying images, and the backlight side is a side incapable of displaying images.
