Abstract
An AC thin film electroluminescent display panel includes a metal assist structure formed on and in electrical contact over each transparent electrode, and a graded layer of light absorbing dark material which combine to provide a sunlight viewable display panel.
Claims20
A sunlight viewable electroluminescent display panel, comprising:
- a glass substrate;
- a plurality of parallel transparent electrodes deposited on said glass substrate, each of said transparent electrodes having a metal assist structure formed on, and in electrical contact over, a portion of said transparent electrodes;
- a first dielectric layer deposited on said plurality of transparent electrodes;
- a layer of phosphor material deposited on said first dielectric layer;
- a second dielectric layer deposited on said layer of phosphor material;
- a graded layer of light absorbing dark material, deposited on said second dielectric layer, for reducing reflected light;
- and
- a plurality of metal electrodes each deposited in parallel over said layer of light absorbing dark material.
