DUAL SIDE VIEW WAVEGUIDE LIQUID CRYSTAL DISPLAYS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17875779 titled 'DUAL SIDE VIEW WAVEGUIDE LIQUID CRYSTAL DISPLAYS

Simplified Explanation

The dual side view display described in the patent application includes a waveguide with two transparent layers, one inside and one outside, that are parallel and spaced apart. Inside the waveguide, there are multiple liquid crystal (LC) pixels for both inside and outside viewing. The inside LC pixels have blocking layers to prevent scattered light from propagating through the outside transparent layer, while the outside LC pixels have blocking layers to prevent scattered light from propagating through the inside transparent layer.

• The patent describes a dual side view display with a waveguide and transparent layers.
• Inside the waveguide, there are LC pixels for both inside and outside viewing.
• The inside LC pixels have blocking layers to prevent scattered light from going outside.
• The outside LC pixels have blocking layers to prevent scattered light from going inside.

Potential applications of this technology:

• Dual side view displays for electronic devices such as smartphones, tablets, and laptops.
• Advertising displays that can show different content on each side.
• Public transportation displays that can provide information to passengers on both sides of the vehicle.

Problems solved by this technology:

• Eliminates the need for separate displays for inside and outside viewing.
• Reduces the amount of scattered light that can interfere with the display quality.
• Provides a compact and efficient solution for dual side view displays.

Benefits of this technology:

• Improved user experience with dual side viewing capabilities.
• Enhanced visibility and readability of displayed content.
• Cost-effective solution compared to using separate displays for inside and outside viewing.

Original Abstract Submitted

A dual side view display includes a waveguide with an inside transparent layer and an outside transparent layer spaced apart from and parallel to the inside transparent layer, and a plurality of inside view liquid crystal (LC) pixels and a plurality of outside view LC pixels disposed within the waveguide. The plurality of outside view LC pixels are disposed within the waveguide parallel to and in-plane with the plurality of inside view LC pixels. The plurality of inside LC pixels includes a plurality of outside blocking layers configured to block light scattered in the plurality of inside view LC pixels from propagating through the outside transparent layer. Also, the plurality of outside view LC pixels includes a plurality of inside blocking layers configured to block light scattered in the plurality of outside view LC pixels from propagating through the inside transparent layer.
