NON-LIGHT-EMITTING VARIABLE TRANSMISSION DEVICE AND A METHOD OF FORMING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240019749 titled 'NON-LIGHT-EMITTING VARIABLE TRANSMISSION DEVICE AND A METHOD OF FORMING THE SAME

Simplified Explanation

The abstract describes a non-light-emitting variable transmission device that includes an active stack, a transparent conductive layer, an antireflective layer, and a bus bar. The bus bar is made of a conductive tape and contacts the transparent conductive layer without the need to cut it.

  • The device includes an active stack, transparent conductive layer, antireflective layer, and bus bar.
  • The bus bar is made of a conductive tape and contacts the transparent conductive layer.
  • The device does not require cutting the underlying transparent conductive layer.
  • The antireflective layer is patterned to define a hole that extends to the transparent conductive layer.
  • Improved control in patterning allows for a relatively thin antireflective layer that does not remove too much of the underlying transparent conductive layer.

Potential applications of this technology:

  • Smart windows or glass that can adjust their transparency.
  • Electronic displays with variable transmission capabilities.
  • Privacy screens that can be adjusted to block or allow light.

Problems solved by this technology:

  • Allows for an electrical connection to the transparent conductive layer without cutting it.
  • Enables the formation of a non-light-emitting variable transmission device without damaging the underlying layers.

Benefits of this technology:

  • Simplifies the manufacturing process by eliminating the need to cut the transparent conductive layer.
  • Provides improved control in patterning the antireflective layer.
  • Allows for the creation of thinner antireflective layers, preserving the underlying transparent conductive layer.


Original Abstract Submitted

a non-light-emitting variable transmission device can include an active stack; a transparent conductive layer overlying the active stack; an antireflective layer overlying the transparent conductive layer and defining a hole; and a bus bar comprising a conductive tape that extends into the hole and contacts the transparent conductive layer. proper selection of materials and design of a bus bar can allow an electrical connection to be made to the transparent conductive layer without the need to cut an underlying transparent conductive layer. a method of forming the non-light-emitting variable transmission device can include patterning the antireflective layer to define the hole that extends to the transparent conductive layer. improved control in patterning allows the antireflective layer to be relatively thin and not remove too much of the underlying transparent conductive layer.
