Abstract

The invention discloses a projection device. The projection device (400) comprises a projection screen (100) and a first lens mechanism (200), wherein the first lens mechanism (200) comprises a diffraction structure (210) and a refractive index compensation layer (220), the first lens mechanism (200) and the projection screen (100) are oppositely arranged, and the refractive index compensation layer (220) and the diffraction structure (210) are superposed in the light transmission direction of the first lens mechanism (200). According to the scheme, the problem that the wearing feeling of a user is poor due to the fact that the boundary dimension and the weight of the intelligent glasses are large can be solved. The invention further discloses intelligent glasses. The intelligent glasses comprise a glasses main body (500) and the projection device (400), the glasses main body (500) comprises glasses lenses (530), the glasses lenses (530) are opposite to the projection device (400), andlight projected by the projection screen (100) can be projected to the glasses lenses (530) after passing through the first lens mechanism (200).

Description

Technical field[0001]This application belongs to the technical field of smart glasses, and specifically relates to a projection device and smart glasses.Background technique[0002]With the development of smart glasses, users have higher and higher requirements for smart glasses. The smart glasses can project a virtual image through a projection device configured by itself, so that the user can see the virtual image.[0003]The current smart glasses projection device includes a large number of lenses to balance or eliminate the chromatic aberration generated during the projection process, thereby improving the accuracy of light modulation. However, a larger number of lenses used to eliminate chromatic aberration will result in a larger projection device, which in turn will result in a larger size and weight of the smart glasses, and ultimately result in a relatively bulky smart glasses. Obviously, this will cause the user's wearing experience to be poor.Summary of the invention[0004]The...
