LIGHT FIELD DISPLAY

Smart overview of the Invention

A light field device comprises multiple microdisplays and a series of lenses designed to refract light emitted from these displays. The structure includes first lenses situated on the microdisplays, which help in directing light output, and second lenses placed on top of the first lenses to further manipulate the light. Each microdisplay features a light emitting region filled with micro-LEDs, surrounded by a bezel region. Notably, the pitch of the second lenses is greater than that of the first lenses, allowing for enhanced light refraction and image quality.

Background and Development

The evolution of electronic devices has led to significant advancements in display technology, particularly in televisions. As displays have improved, so has the capability to present diverse content types, including three-dimensional (3D) visuals. Current stereoscopic systems can be divided into those requiring glasses and those that do not. While glasses-based systems offer a satisfactory experience, they come with inconvenience, prompting a push towards glasses-free technologies that can deliver 3D imagery without additional accessories.

Challenges with Existing Systems

Glasses-free systems utilize multiple light field images captured from various viewpoints to create a stereoscopic effect. However, achieving the necessary spatial resolution for effective light field displays remains a challenge compared to traditional displays. The presence of a bezel region around microdisplays can hinder the realization of large-scale light field displays. Addressing this issue is crucial for optimizing 3D image quality while minimizing the bezel's impact.

Technical Specifications

The proposed light field device aims to mitigate bezel interference through an innovative lens arrangement. The first lenses are designed with specific optical apertures, which overlap in a predetermined ratio to enhance performance. Each lens type is tailored to correspond with specific micro-LEDs within the microdisplays, ensuring efficient light refraction. Additionally, materials such as resin or glass may be used between the lens layers to improve overall functionality and image clarity.

Operational Framework

The device integrates a memory and processor that control the display functionality through pre-defined instructions. This system allows for seamless interaction between the microdisplays and the lens configuration, ensuring high-quality stereoscopic images are presented effectively. By leveraging advanced optics and microdisplay technology, this light field display represents a significant step forward in delivering immersive visual experiences without the need for glasses.
