Abstract
An image display system having a plurality of light emitting cells (EL.sub.11 -EL.sub.44) each having a pair of Electro-Luminescence elements (e.sub.1, e.sub.2) coupled in parallel with each other with opposite polarities. The light emitting cells are arranged on a cross point of a matrix, which is addressed through an active addressing method in which a plurality of rows of the matrix are selected simultaneously, and alternate voltage is applied to the matrix.
Claims5
An image display system comprising:
- a plurality of light emitting cells having thin film structure arranged on a planar screen,
- wherein each light emitting cell has at least a pair of light emitting elements each having the same rectifying characteristics, and
- wherein at least two of said light emitting elements are coupled in parallel with each other with opposite polarities so that an anode of a first light emitting element is connected to a cathode of a second light emitting element and a cathode of the first light emitting element is connected to an anode of the second light emitting element, and
- wherein said cells are located on each cross point of a matrix, which is addressed through an active addressing method in which a plurality of rows are selected simultaneously, and alternate voltage is applied to said matrix.
