Abstract

The invention discloses a micro projector module and a display device. The micro projector module comprises a display module, a lens set module and a refraction adjusting module. The display module comprises a display unit and a fixing rack fixing the display unit, wherein the display unit is used for displaying input data. The lens set module comprises a set of lenses and a lens set rack used for fixing each lens, wherein the set of lenses are used for performing refractive imaging adjustment on light emitted by the display unit. The refraction adjusting module is in connection with the display rack and the lens set rack, and is used for allowing the display module to perform straight reciprocating motion relative to the lens set module by utilizing the cam principle. The micro projector module realizes modularization design and application, has the characteristics of concise and compact structure, and high precision, and is more comfortable to wear. In addition, the micro projector module also comprises a refraction adjusting mechanism which can rapidly and conveniently adjust refraction effects, so that users with farsightedness or shortsightedness can use the micro projector module without wearing glasses, thereby greatly improving user experience.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a micro-projection module and a display device. Background technique [0002] At present, the design of the display device is not fine enough, the mechanism is complicated, and the volume is large, and most of the existing display devices are more convenient for users with normal vision, but inconvenient for users with visual impairments, such as nearsightedness or hyperopia. It is often necessary to wear glasses to use the device, resulting in a poor user experience for visually impaired users. Contents of the invention [0003] The present invention provides a micro-projection module and a display device to solve the problem that the design of the existing display device is not fine enough, and it does not have a diopter adjustment function, resulting in poor user experience for visually impaired users. [0004] In order to achieve the above object, technical solutio...
