Title:
DRIVING CIRCUIT AND SELF-SCANNING LED ARRAY EQUIPPED WITH THE SAME
Document Type and Number:
Japanese Patent JPH09248936
Kind Code:
A
Abstract:
To reset a transfer action in case of transfer abnormality in a self- scanning LED array.
A pulse signal is output from an output generation part A to the cathode of a thyristor for transfer. The peak of the pulse signal is compared with a standard digital signal in a digital comparator 203, and when they agree with each other, a coincidence signal is sent to CPU 204. The CPU 204 which received the signal acts to increase the bias voltage of a transistor 122, and as a result, transfer action can be reset.
