As described above, since the conventional commonly used near-eye display device is equipped with the eye tracking device, the infrared light source and the infrared camera are both independent from the near-eye display device and are located in front of or in front of the side of the near-eye display device, which increases the volume of the near-eye display device in front of or in front of the side of the eye, so that the whole weight of the near-eye display device is unbalanced, the front is heavy, the back is light, and the device is not convenient to fix during wearing.
SUMMERY OF THE UTILITY MODEL
Based on the problem that prior art exists, the utility model aims at providing a near-to-eye display device with eyeball tracking function, under the prerequisite that does not influence eyeball tracking, reduce near-to-eye display device people's eye the place ahead or the volume in side the place ahead.
The utility model aims at realizing through the following technical scheme:
an embodiment of the utility model provides a near-to-eye display device with eyeball tracking function, include: the system comprises a micro display screen, an infrared light source, an infrared camera and a conduction light path; the infrared light source and the infrared camera are both arranged on the periphery of the micro display screen and are positioned on the side face of the eyeball of the user;
the infrared light transmitting end of the infrared light source and the infrared light receiving end of the infrared camera face the conduction light path, and infrared light transmitted by the infrared light source is reflected by eyeballs of a user through the conduction light path and then is conducted to enter the infrared camera.
By the foregoing the utility model provides a technical scheme can see out, the embodiment of the utility model provides a near-to-eye display device with eyeball tracking function, its beneficial effect is:
through with infrared light source, infrared camera all establishes in little display screen periphery, and be in the side of user's eyeball, with the light path of conduction light path infrared reflection user eyeball to infrared camera as infrared light source, make convenient integration near-to-eye display device inside with infrared light source and infrared camera, and keep away from user's eyeball, and rather than being independent of near-to-eye display device and establishing in its place ahead or side the place ahead, the volume in near-to-eye display device the place ahead or side the place ahead has effectively been reduced, make near-to-eye display device whole weight more balanced, more convenient to use person wears, it stabilizes to be more convenient for in wearing.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the specific contents of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Details not described in the embodiments of the present invention belong to the prior art known to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a near-to-eye display device with an eyeball tracking function, including: the system comprises a micro display screen, an infrared light source, an infrared camera and a conduction light path; the infrared light source and the infrared camera are both arranged on the periphery of the micro display screen and are positioned on the side face of the eyeball of the user; the infrared light transmitting end of the infrared light source and the infrared light receiving end of the infrared camera face the conduction light path, and infrared light transmitted by the infrared light source is reflected by eyeballs of a user through the conduction light path and then is conducted to enter the infrared camera.
In the near-to-eye display device, the infrared light source and the infrared camera are respectively arranged at the periphery of the projection lens of the micro display screen. Preferably, the infrared light source and the infrared camera are symmetrically arranged with the projection lens of the micro display screen as the center.
In the near-to-eye display device, the infrared light source and the infrared camera can adopt a common infrared light source and a common infrared camera.
In the near-to-eye display device, the conduction light path is composed of conduction lenses.
The utility model discloses an all establish infrared source and infrared camera little display screen periphery, the integration has been in near-to-eye display device, and the place ahead or the side the place ahead of near-to-eye display device are independently established to the non-, when having realized eyeball tracking function, the volume in near-to-eye display device the place ahead or the side the place ahead has effectively been reduced for whole near-to-eye display device size, weight are more balanced, do not have the big back in the front little, the light problem in the heavy back in the front, it is fixed to change when making to wear, the steadiness of wearing is better.
