Pixel-based curved surface near-to-eye display method, displayer and display system

Abstract

The invention relates to the technical field of near-to-eye display, and in particular, relates to a pixel-based curved surface near-to-eye display method, a displayer and a display system. A plurality of transmission type LCD units or reflection type EW units are utilized to form a curved surface panel, and natural light is adopted as a light source of the LCD units or the EW units; and liquid crystal pixel emergent light rays of all the LCD units or oil film pixel reflected light rays of the EW units are focused to the same focus point, and the focus point is located on the vertical center line of the curved surface panel and falls into eyeballs of a user. According to the invention, only the distance between the focal length and the curved surface during imaging of the curved surface pixel is changed, so that an ideal mode for enlarging the field angle in near-to-eye display is provided; and meanwhile, the natural light transmission of the transparent curved surface is not changed when the emergent ray angle or the reflected ray angle during imaging of the pixel is changed; therefore, co-existence of virtual information and reality information is guaranteed, and a good AR effect is achieved.

Description

technical field [0001] The invention relates to the technical field of near-eye display, in particular to a pixel-based curved near-eye display method, display and display system. Background technique [0002] Augmented reality (Augmented Reality, referred to as AR) technology is a technology that ingeniously integrates virtual information with the real world. Computer-generated text, images, 3D models, music, video and other virtual information are simulated and applied to the real world. The two kinds of information complement each other, thereby realizing the "enhancement" of the real world. [0003] Since the beginning of the 20th century, with the development of AR technology, more and more well-known electronics manufacturers have devoted themselves to the research of AR products. For example, Google in the United States and Epson in Japan have successively launched their own smart glasses products. [0004] As shown in Table 1, the optical display systems used in exi...

Simply put, this refraction structure is essentially an optical waveguide structure, which is no different from the optical waveguide in the principle of imaging light output. When applied to products similar to AR glasses, the refraction structure will interfere with half of the natural light and make half The angle of natural light is deflected, which means that if you want to avoid the deflection of natural light, you can only use a normally black screen structure, which will inevitably cause a decrease in light transmittance. disorder
