Panel structure for producing plate type LED substrates

The utility model discloses a plate surface structure for preparing a base plate. The plate surface structure is technically characterized in that the structure comprises a whole metal plate, a plurality of structural units are arrayed on the whole metal plate, the structural units have electrode extending structures with concave and convex matched and mutually spaced, connecting bars are arranged between two adjacent structural units, and a connecting frame is arranged on the periphery of a plurality of structural units. The utility model has the advantages of high production efficiency, good heat radiation effect, high light extraction efficiency, and convenient application, thereby being especially suitable for the mass production of sheet type light emitting diodes.
