Abstract
Methods of forming polarized panes for variable transmission windows are disclosed. The polarized panes are formed from transparent substrates that are brushed with a brushing pattern that varies continuously in a select direction over each of one or more periods. A layer of polarizable material such as POLARCOAT material can be deposited on and responds to the brushed surface by forming a polarization pattern that substantially matches the brushing pattern and thus also includes one or more periods.
Claims20
A method of forming a polarized pane for a window having a variable transmission, comprising:
- brushing a surface of a transparent plate to create a brushed surface having a brushing pattern, wherein the brushing pattern has at least one period and varies continuously in a select direction within each period;
- and
- depositing a polarizable material on the brushed surface to form a polarization pattern in the polarizable material substantially following the brushing pattern.
A method of forming a polarized pane for a variable transmission window, comprising:
- brushing a surface of a transparent plate while using a mask to continuously vary an amount of exposed surface to create a brushing pattern that varies continuously in a select direction for each of one or more periods;
- and
- depositing a layer of polarizable material on the brushed plate surface to create a polarization pattern substantially matching the brushing pattern.
A method of forming a polarized pane using a glass plate having a surface, comprising:
- brushing the surface to form a brushing pattern that varies continuously in a select direction for each of multiple periods, wherein the brushing pattern in each period is substantially identical;
- and
- coating the brushed surface with a polarizable material to create a polarization pattern having the same number of multiple periods as and being substantially identical to the brushing pattern.
