CURRENT GENERATION SUPPLY CIRCUIT AND DISPLAY DEVICE, ESPECIALLY SETTING OUTPUT CURRENT RELATIVE TO THE REFERENCE CURRENT TO BE A PLURALITY OF STAGES

摘要

PURPOSE: A current generation supply circuit and a display device are provided to improve display response characteristics and to reduce power consumption, and to improve display image quality by improving brightness. CONSTITUTION: A reference voltage generation circuit is installed in each load and is supplied with a reference current, and then it generates a reference voltage on the ground of the corresponding reference current. A driving current generation circuit(TPC) generates an output current having a current value having a ratio according to a digital signal as to the reference current on the ground of the reference voltage. And a current generation circuit(CLM) has a characteristics control circuit setting a ratio of the output current as to the reference current, and supplies the output current to each load as a driving current.
