BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting element driving apparatus, and more particularly, to a driving apparatus capable of driving a mechanical light emitting element, an electroluminescence element and a mechanical-electrical combined light emitting element.

Electroluminescence refers to a phenomenon in which light is emitted from a phosphor by using an electric potential difference as an excitation energy when an electric field is applied to the organic or inorganic light emitting layer. In this case, an inorganic material or an organic material capable of emitting fluorescence may be used as the light emitting material. The organic or inorganic light emitting layer may be composed of a host ion (ZnS) and an activator ion (Cu and Mn), and various luminescent hues can be realized by applying various active ions.

Mechano-luminescence is a phenomenon that occurs by applying a force (mechanical external force) to a material, that is, a phenomenon that emits light in a mechanical manner. It has long been called Mechanoluminescence (upper concept including piezoluminescence, triboluminescence, fractoluminescence and deformation-luminescence) However, since the luminescence intensity is not so strong and it is difficult to apply to the present, it is treated as an academic interest.
