Problems solved by technology
When the human eye stares at the LCD screen for a long time, it is easy to cause visual fatigue, which has always caused vision loss, and the existing monitors are public monitors, and everyone can watch and share the content on the monitors, and the video information cannot be private. Therefore, there is a need to develop a display device that displays private content and can directly project pictures to the user's eyes without going through a liquid crystal display, and is not easy to cause visual fatigue.

Embodiment Construction
[0018] The specific implementation case of the present invention is described below in conjunction with accompanying drawing:
[0019] Such as figure 1 As shown, a virtual retina display technology includes: a signal source 1, an image processing module 2 and a lens 3, wherein the signal source 1 adopts a low-power LED, and the low-power LED is used to emit an analog light source to form a Picture; described image processing module 2 adopts micromirror array (micromirror array (TRP) technology is microlens technology again, uses DLPPico chipset, has a tiny sensor in each pixel point of active matrix LCD panel, controls Light transmission "off" or "on", these sensors block part of the light passing through the light transmission point, thus reducing the light transmittance and affecting the image brightness of the projected screen. Microlens technology uses a Tiny lenses gather light through the light-transmitting point, avoiding the sensor, allowing more light to pass through...

The present invention discloses a virtual retina display technology. A virtual retina display device comprises: a signal source, an image processing module and a lens. The signal source is used for emitting an analog light source to form a picture. The image processing module adopts a micromirror array technology to adjust a shape and sharpness of the picture. The lens is a focusing lens, and is used for focusing an image and projecting the focused image onto a retina of a user. The signal source is connected with the image processing module by an electrical signal; the analog light source emitting by the signal source form the picture; then the image processing module adjusts the shape and sharpness of the picture; and finally the picture is focused on the retina of the user by using the lens. By using the technology and the device provided by the present invention, a user, without using a liquid crystal display, can directly see image information sent by a signal source, and a long period of viewing does not cause visual fatigue, thereby effectively protecting vision of the user.
Description
technical field [0001] The invention relates to the field of optical display instruments, in particular to a virtual retina display technology and a virtual retina display device. Background technique [0002] Display refers to a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye, such as large screens, TVs, BSV liquid crystal splicing fluorescent screens, mobile phones, and Kuaidong. . When the human eye stares at the LCD screen for a long time, it is easy to cause visual fatigue, which has always caused vision loss, and the existing monitors are public monitors, and everyone can watch and share the content on the monitors, and the video information cannot be private. Therefore, there is a need to develop a display device that displays private content and can directly project pictures to the user's eyes without using a liquid crystal display screen, and does not easily cause visua...
