Abstract: A photosensitive chip includes a photosensitive array and a target transmission channel. The photosensitive array is configured to generate an induced electrical signal. A target image signal is generated from the induced electrical signal through the target transmission channel. The target image signal is used to generate a target image. Target image represents a change in a target space.

Abstract: The embodiments of the present invention provide a proximity sensing device and a method for manufacturing the same, and an electronic device. The proximity sensing device includes: a window; a signal transmitting element integrated at an inner side of the window, to transmit an optical signal to an outer side of the window; and a signal sensing element integrated at the inner side of the window and disposed side by side with the signal transmitting element, to sense an object at the outer side of the window by receiving the optical signal reflected by the object. Through the embodiments of the present invention, the gap between the signal transmitting element, the signal sensing element and the window needs not to be considered too much, the integration process becomes easily controllable, and the light leakage is greatly reduced.
