Problems solved by technology

[0003] However, in the existing optical projection method, the Logo is imaged through a transparent plate (upper and lower transparent planes), at this time, two virtual images will be generated, resulting in double images
Moreover, the virtual image presented with a ratio of 1:1 needs to increase the projection space if the imaging size needs to be increased, which is not conducive to the miniaturization of electronic devices.

Embodiment Construction

[0018] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0019] Certain terms are used in the description and claims to refer to particular elements. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same element by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Include" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In the description of the present invention, the terms "first", "second" and the like are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0020] The present invention will...

Abstract

The invention discloses an optical projection device and an electronic device. The optical projection device is used for optical projection of a label, and the optical projection device comprises a light source unit and a projection unit, wherein the projection unit is solid and transparent, and the projection unit is provided with a first surface and a second surface which are intersected; after the light source unit irradiates the label, light enters the projection unit from the first surface and then is emitted from the second surface to form a virtual image of the sign. According to the optical projection device, imaging of the label can be achieved through the projection unit, imaging is unique, the problem of double images does not exist, and the good ornamental texture is achieved.

Description

technical field [0001] The invention relates to an optical projection device and an electronic device with the same, in particular to an optical projection device without ghosting and an electronic device with the same. Background technique [0002] With the development of technology, people are pursuing more and more high-quality electronic devices, and the expression of product signs (Logo) is becoming more and more technological. For example, the logo expression method has changed from the original physical method of printing or nameplate to the imaging method of optical projection. [0003] However, in the existing optical projection method, the Logo is imaged through a transparent plate (upper and lower transparent planes), and at this time, two virtual images will be generated, resulting in a double image. Moreover, if the virtual image presented with a ratio of 1:1 needs to be enlarged, the projection space needs to be increased relatively, which is not conducive to ...
