Waveguided Display Systems with Dynamic Tinting - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240353684 titled 'Waveguided Display Systems with Dynamic Tinting
The display system described in the patent application includes a waveguide with an output coupler that directs image light towards an eye box, while also transmitting world light from real-world objects towards the eye box. An adjustable tint layer with multiple states is positioned between a bias lens and the output coupler, allowing for different amounts of world light to pass through and potentially imparting different colors or transmission characteristics to the light. The bias lens itself may serve as the adjustable tint layer, with a transparent electrode layer that can be heated by AC voltages to adjust the tint. The adjustable tint layer may be a self-switching electrochromic device with a transparent solar cell.

Original Abstract Submitted
a display system may include a waveguide with an output coupler that couples image light out of the waveguide and towards an eye box. the output coupler may also transmit world light from real-world objects towards the eye box. a bias lens may pass the world light to the output coupler. an adjustable tint layer having multiple states that involve transmission of different amounts of the world light may be disposed between the bias lens and the output coupler. different states may impart different colors and/or may impart a gradient transmission characteristic to the world light. the bias lens itself may form the adjustable tint layer. the adjustable tint layer may have a transparent electrode layer that is provided with one or more ac voltages that heat the adjustable tint layer. the adjustable tint layer may be a self-switching electrochromic device that includes a transparent solar cell.
