<p>PURPOSE:To flatten the lines of an image by setting up the correcting resistance value of a current correcting resistor so that a partial light emitting element emits the different quantity of light as compared to another light emitting element. CONSTITUTION:Driving ICs 131, 132 are arranged on both the sides of an LED chip 12 and connected by bonding wires so that respective driving ICs are driven by the opposite side driving ICs every other dot. The current correcting resistors 151, 152 of respective driving ICs are connected by the bonding wires 16. The quantity of light of the LED arrays is controlled by the current correcting resistors, the resistance vlaues of these resistors are changed so that the adjacent LED arrays emit different quantity of light each other to set up the correcting resistance values. Consequently, the ruggedness of a linear image can be reduced and the lines of the image can be flattened.</p> |
