  • Solid seal for thin film electroluminescent display panels
    Patent number: 5194027
    Abstract: A construction for a TFEL panel includes a solid encapsulating layer for the active area of a TFEL panel that has a hardness that does not exceed 40 duromeers (Shore A). A gel material is spread over the active area and cured to the desired degree of hardness. At this degree of hardness the panel retains its self-healing characteristics and the panel's durability is much improved over designs using oil-filled cavitites.
