Patent ID: 7325945

Claim:
An electronic device comprising: a display panel; a circuit board, comprising a control circuit formed thereon; a plurality of light penetrating portions alternatively disposed on the display panel, the light penetrating portions having a plurality of hollow holes spacedly formed on the display panel, each hollow hole being positioned between two of the adjacent hollow holes of the light penetrating portions, thereby forming the hollow holes in a chess-board shape; a light emitting circuit board, which is disposed between two adjacent light penetrating portions, wherein a plurality of light emitting elements is disposed on two sides of the light emitting circuit board corresponding to the hollow holes, thereby forming a light emitting unit comprising the hollow holes and the light emitting elements; and a conducting circuit, which is disposed on the light emitting circuit board, connected with the light emitting elements, and further connected to the control circuit via at least a transmission line, so as to control the light emitting status of the light emitting element by the control circuit via the transmission line and the conducting circuit.
