Abstract
Separate circuit sections of active driver circuits located adjacent at least one side of a liquid crystal display have a first encapsulating material covering each of the active driver circuits separately and a second encapsulating material covering all of the active driver circuits and their first encapsulating layer. The active driver circuits may also be sealed between two spaced bands forming an enclosure between the substrates and having an opening in the outer seal to allow a fluid to be inserted in the enclosure formed by the two seal bands to protect the active driver circuits therein. The opening may be sealed with an adhesive.

A system for protection of a liquid crystal display device having a display area and that includes active driver circuits integrally formed on a first substrate, the system including:
- n separate spaced circuit sections forming the active driver circuits, each of said n spaced circuit sections being formed on the first substrate adjacent at least one side of the display area of the liquid crystal display;
- a first protective coating material separately covering and encapsulating each of the n circuit sections of said active driver circuits, said first protective coating adhering to the first substrate for protecting the active driver circuits;
- and
- a second outer protective coating material continuously covering and encapsulating all of the n circuit sections of said active driver circuits to enhance protection of the active driver circuits.
A system for protection of an active driver circuit integrally formed on one of first and second spaced substrates having a liquid crystal display area, the system including:
- at least one elongated active driver circuit formed on the first substrate adjacent the liquid crystal display area;
- first and second spaced seals between the first and second spaced substrates to form an enclosure substantially surrounding said display area;
- said first seal surrounding and enclosing said liquid crystal display area in a liquid-tight fashion;
- and
- said second seal being spaced from said first seal and forming said enclosure with said first seal to seal the at least one elongated active driver circuit in said enclosure formed between said first and second substrates by said first and second spaced seals.
