Abstract
The electrodes of a electro-optic device having a flexible electrode bearing member, such as a silicon integrated circuit, are re-contoured as required to generally conform to the mating surface of the electro-optic element by resiliently biasing the electrode bearing member against that surface. The bias is suitably supplied by a compressed elastomeric pressure pad which underlies the flexible electrode bearing member. The pressure pad is substantially coextensive with the electrode bearing portion of the flexible member so that a more or less uniform bias is applied throughout that area.
Claims8
In an electro-optic device including
- an electro-optic element,
- a flexible member, and
- a plurality of electrodes supported in spaced apart relationship on said flexible member, said electrodes facing a surface of said electro-optic element and being intimately coupled thereto to proximity couple electric fields into said electro-optic element;
- the improvement comprising
- a rigid base plate, and
- resilient means compressed between said flexible member and said base plate for applying a distributed bias to said flexible member, said bias urging said flexible member toward said surface, thereby causing said electrodes to generally conform to said surface.
