Abstract
A display panel comprising of a semiconducting oxide between layers of a hole injector and an electron injector. The electron injector contains a metal oxide in a fine particulate form. When the electron injector is biased negatively with respect to the hole injector, both holes and electrons are injected and an image is formed by the trapping of electrons in color centers in the oxide layer. Reverse biasing erases the image.
