Problems solved by technology

[0002] Existing three-dimensional (Three Dimensional, 3D) sensing modules usually use a laser with concentrated emission energy as a light source to project a sensing light pattern, so once the optical element arranged on the light output side of the light source for forming structured detection light is damaged If not, the high-energy laser will directly irradiate the user's eyes and cause damage

Abstract

The application provides a transmitting unit, which comprises a first modulation element and a detection processor. The first modulation element comprises a first electrode, a second electrode, and amodulation layer disposed between the first electrode and the second electrode. The first electrode and the second electrode are used for applying an electric field to the modulation layer, and the modulation layer can be switched at least between a transparent state and a scattering state along with the change of the electric field intensity of the electric field so as to modulate the transmittedlight. The detection processor is respectively connected with the first electrode and the second electrode, and is used for detecting the electrical property value of the first modulation element through the first electrode and the second electrode and judging whether the first modulation element is damaged or not according to the detected electrical property value of the first modulation element.

Description

Technical field [0001] This application belongs to the field of optical technology, and in particular relates to a transmitting unit, a sensing module and an electronic device. Background technique [0002] The existing Three Dimensional (3D) sensing module usually uses a laser with relatively concentrated emission energy as the light source to project the sensing light pattern, so once it is installed on the light source side of the light source, the optical element used to form the structured detection light is damaged. Otherwise, the high-energy laser will directly irradiate the user’s eyes and cause damage. Summary of the invention [0003] The technical problem to be solved by this application is to provide a transmitting unit, a sensor module and an electronic device to solve the above technical problem. [0004] The embodiment of the present application provides a transmitting unit, which includes a first modulation element and a detection processor. The first modulation el...
