Electroluminescent bargraph with integral thin-film transistor control circuitry

摘要

An electroluminescent bargraph display module is detailed with an integral multi-stage thin-film transistor dynamic shift register disposed upon the module substrate side-by-side with the individually controllable electroluminescent display elements. The shift register accepts serial digital data input and holds it stationary in the register and supplies parallel outputs from the respective stages which are connected to individual display elements.
