Display module position adjusting device and display equipment

Abstract

The invention discloses a display module position adjusting device comprising a fixed seat, a first adjusting portion, a second adjusting portion and a third adjusting portion; the first adjusting portion is movably connected with the fixed seat along the X shaft; the second adjusting portion is movably connected with the first adjusting portion along the Y shaft; the third adjusting portion is movably connected with the second adjusting portion along the Z shaft; an image source used for emitting image lights is fixedly connected with the third adjusting portion. The first adjusting portion can be adjusted so as to adjust the position of the image source in the X shaft direction, the second adjusting portion can be adjusted so as to adjust the position of the image source in the Y shaft direction, and the third adjusting portion can be adjusted so as to adjust the position of the image source in the Z shaft direction, thus adjusting the image source 3D positions at will, adjusting theexit pupil position of the image source at will, adapting to different populations, and preventing the technical problems that the equipment needs to singly customize products according to individualdemands and is hard for mass production.

Description

technical field [0001] The invention relates to the technical field of near-eye display, in particular to a display device for adjusting the position of a display module. Background technique [0002] At present, the AR near-eye display system composed of scanning image sources, such as the lens-type retinal scanning display invented by the Japanese brother company, and the Vaunt smart glasses released by Intel, etc., the main structure includes an image source composed of a light source 10 and a scanner 11, and an imaging system. Lenses 12, such as figure 1 As shown, the imaging principle is that the light beam emitted by the light source 10 is irradiated on the scanner 11, and the scanner 11 undergoes two-dimensional vibration scanning to realize a plane image, and the scanned image passes through the imaging lens 12, and then focuses near the pupil of the human eye to realize retina Direct Imaging Display. Reference may be made to US patents US20020085175A1 and US647481...

AI Technical Summary

Problems solved by technology

[0003] This technology has certain mass production problems. Due to the limitation of its imaging principle, the exit pupil diameter of this technical solution is very small, and the focus spot has only a small exit pupil observation range near the pupil of the human eye, which is easy to lose the field of view and is inconvenient to use; Moreover, different groups of people have different head structures. In order to adapt to different groups of people, it is necessary to customize products for each individual, which is not easy for mass production.
