Abstract

The embodiment of the invention discloses a micro-projector and a brightness adjustment method thereof as well as a portable device. The micro-projector comprises an input power identification unit, a brightness setting unit and a brightness adjustment unit, wherein the input power identification unit is used for identifying the output power of a power adapter; the brightness setting unit is used for setting the brightness of the micro-projector according to the input power of the power adapter identified by the input power identification unit; and the brightness adjustment unit is used for adjusting the brightness output by the micro-projector to the brightness set by the brightness setting unit. According to the embodiment of the invention, the brightness of the micro-projector can be adjusted according to the output power of the power adaptor.

Description

technical field [0001] The invention relates to the technical field of micro-projectors, in particular to a micro-projector, a method for adjusting brightness thereof and a portable device. Background technique [0002] Compared with ordinary projectors, mini projectors are much smaller in size and are convenient for users to carry. It is designed with a fixed brightness output and must be equipped with a power adapter with a fixed output power. For example: if the brightness of the miniature projector is set to high lumens (for example: 100 lumens), you need to be equipped with a power adapter with an output power of 90 watts; if the brightness of the miniature projector is set to low lumens (for example: 75 lumens), A power adapter with an output power of 65 watts is required. [0003] The inventor found in the research process that the output power of the power adapter is fixed, for example: 90 watts or 65 watts. For users who have a power adapter with an output power o...
