Abstract
A non-planar electronic light-emitting display has a display area divided into a matrix of pixels. Each pixel includes two primary elements, an electronic driver and a light-emitting diode based on a light-emitting polymer. The electronic driver is a thin film transistor device of amorphous silicon formed on the insulating substrate. The diode has a first electrode connected to and driven by the electronic transistor, a layer of light-emitting polymer deposited on the electrode, and an overlying electrode normally biased on. Energization of the driver biases the diode to cause the polymer to emit light. Each pixel is configured with the two-component structure described above, and row and column lines to the matrix of pixels are decoded by the drivers to cause selective illumination of the pixels.
