PURPOSE: By automatically controlling the scan direction of the light emitting diode to the desired pattern the display panel improves the power efficiency. CONSTITUTION: A case(10) comprises the opening formed in one side. The light emitting diode socket member(22) comprises the joint part(24) preparing in the other side of the connection unit and the connection unit electrically connected with one or more light emitting diodes(21), and the light emitting diode with the sphere shape. A plurality of point source of light assemblies comprises a plurality of point source of light assemblies expressing the predetermined character or image according to the flash of the light emitting diode and input unit. A point source of light assembly supporting part(30) is fixed to the case. A plurality of fitting holes is formed in the point source of light assembly supporting part. The circuit board(40) comprises a plurality of point source of light assemblies and the electrically connected wirings. The controller(50) controls light emitting diodes. |
