Embodiment 1

[0047] A dual-mode head-mounted display device, including an image source, a control module, a display module and a power module, and the power module provides the working power of the system; the display module includes a shading module 1, a zoom module 3, and a 1 and the beam conducting module 2 between the zoom module 3;

[0048]The shading module 1 is connected with the control module signal, and the shading module 1 can adjust the transmitted light intensity according to the signal of the control module; the image source includes a camera module, and the camera module is used to scan the scene and reconstruct to obtain a virtual image and Gesture recognition, external ambient light intensity, the specific image source can be any one of LCOS image source, OLED image source, LCD image source, SLM image source, DMD image source; the transmission of external light by the shading module 1 The rate is 0% to 100%. When the light intensity of the external environment changes, the...

Embodiment 2

[0052] The parts of this embodiment that are the same as those in Embodiment 1 will not be repeated. The difference is that the shading module 1 is a second shading module 1, including two glass substrates that are oppositely arranged, and the two glass substrates are formed by encapsulating the two glass substrates with a sealing member 303. The first liquid crystal cell 104, the thickness of the first liquid crystal cell is 30-100 μm, the polymer liquid crystal material 304 is encapsulated in the first liquid crystal cell 104, and the polymer liquid crystal material 304 includes a liquid crystal 305 with birefringence and The polymer 306 having the same ordinary light refractive index as the liquid crystal 305, in parts by weight, the polymer liquid crystal material 304 includes 35-45 parts of liquid crystal, 35-45 parts of polymer, 8-12 parts of initiator and 8 parts of surfactant ~12 parts; the liquid crystal 305 is a mixed crystal, and the difference between the ordinary l...

Abstract

The invention discloses a dual-mode head-mounted display device. The device comprises an image source, a control module, a display module and a power supply module, and is characterized in that the power supply module provides a working power supply for a system, the display module comprises a shading module, a zooming module and a light beam conduction module located between the shading module and the zooming module, the shading module is in signal connection with the control module, the shading module can adjust the transmission light intensity according to a signal of the control module, the image source is used for projecting a light beam of a virtual image to the light beam conduction module, and the conduction module projects the light beam to the zooming module and guides the lightbeam to human eyes through the zooming module.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a dual-mode head-mounted display device. Background technique [0002] As a mainstream head-mounted display device implementation technology, virtual reality technology has developed rapidly in recent years. Virtual reality is the ultimate application form of multimedia technology. The crystallization of rapid development in the field of science. It can be widely used in medical fields, entertainment and art fields, military and aerospace fields, management engineering fields, interior design fields, industrial simulation fields, game fields, education fields, etc. [0003] Augmented reality technology originated from virtual reality technology. The technology is a continuum from real to virtual environments, superimposing computer-generated data onto real scenes to enhance the user's understanding of the environment. Therefore, it can be seen that for wearable virtua...
