Abstract
An image element is disclosed having first and second supply terminals, a light emitting semiconductor component, a driver circuit comprising a driver transistor, a storage capacitor, and a switching transistor, and a trigger circuit comprising an output transistor and a control capacitor. The light emitting semiconductor component and the driver transistor are arranged in series with each other and between the first supply terminal and the second supply terminal. A first electrode of the storage capacitor is coupled to a control terminal of the driver transistor. The switching transistor is configured to switch on and off a current flow through the light emitting semiconductor component. A first electrode of the control capacitor is connected to a control terminal of the output transistor. A first terminal of the output transistor is connected to a control terminal of the switching transistor. Furthermore, a method for operating an image element, in particular such an image element, is disclosed.
