Description

Optical lens, display, and connecting member for physically coupling optical lens and display each other Various embodiments of the present invention relate to an optical lens, a display, and a connecting member for physically connecting the optical lens and the display to each other. Augmented Reality (AR) is a technology that superimposes virtual objects or information onto a real-world environment, making them appear as if they exist within the original setting. To implement the aforementioned augmented reality, an optical system is required to transmit a virtual image displayed on a device, such as a computer, to the user's eyes. For example, an optical system for augmented reality generally consists of a display unit that emits virtual image light, an optical module comprising an optical element that transmits the virtual image light emitted from the display unit to the user's eyes, and a lens for transmitting image light from external real objects to the eyes. In addition to optical modules for implementing augmented reality, there is a need to develop various technical elements for the practical application of augmented reality.
