CURRENT DRIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent crosstalk display due to bias voltage variation reducing from induction from a display panel as to a current driving device which drives a display panel such as an organic EL panel with a current.

SOLUTION: The current driving device (10A) is equipped with a plurality of driving circuits (11-1 to 11-m) which drive a plurality of display element circuits of a display panel with currents and a bias circuit (12A) with low-output impedance which generates a bias voltage (Vb) and supplies it to the respective driving circuits (11-1 to 11-m) through a bias line (13). Here, the output impedance of the bias circuit (12A) is set low enough to make voltage variation caused on the bias line (13) due to switching operations of switches (112-1 to 112-n) of the driving circuits (11-1 to 11-m) converge within a writing period of display data.
