Abstract

A liquid crystal cell is presented that utilizes a deposited metal gasket moisture barrier and support membrane bonding two opposing plates of glass, a thin film spacer layer to accurately control cell gap thickness, and an optional integrated thermal sensor and heater deposition layer sandwiched therebetween.

Claims (26)

1. A liquid crystal cell platform, comprising:

a first substrate having a first electrode and first alignment layer,

a second substrate placed in opposition to the first substrate and having a second electrode and second alignment layer,

liquid crystals coupled between the first and second substrates,

a spacer element coupled between the first and second substrates, and

a thin film metal gasket element bonded to the facing surfaces of the first and second substrates,

a sub wavelength optical element or nanostructed grating disposed on said first or second substrate,

active thermal elements disposed on the first and second substrates, and

at least one VIA formed by a layer of the metal gasket element connected to said first or second electrode.

2. A liquid crystal cell platform, comprising:

a first substrate having a first electrode and first alignment layer,

a second substrate placed in opposition to the first substrate and having a second electrode and second alignment layer,

liquid crystals coupled between the first and second substrates,

a spacer element coupled between the first and second substrates and

a thin film metal gasket element bonded to the facing surfaces of the first and second substrates,

a sub wavelength optical element or nanostructed grating disposed on said first or second substrate,

active thermal elements disposed on the first and second substrates, and

at least one VIA formed between the active thermal elements by a layer of the metal gasket element.

3. A liquid crystal cell platform, comprising:

a first substrate having a subwavelength optical element on one side and an electrode and alignment layer on the opposing side,

a second substrate having second electrode and second alignment layers placed in opposition to first substrate electrode and alignment layers,

liquid crystals coupled between the first and second substrates

a spacer element coupled between the first and second substrates,

a thin film metal gasket element bonded to the facing surfaces of the first and second substrates,

active thermal elements that may either be supplied with a voltage to heat the thermal element or whose resistance may be read and measured to determine temperature at any instance, the active thermal elements being deposited onto the first and second substrates,

and wherein a VIA formed by a layer of metal gasket material connects the thermal elements on the first and second substrates.
