摘要:
A light emitting element array that can perform a time-division driving operation with a small number of driving ICs is provided. A light emitting element array chip (1) includes n switch thyristors (S) (wherein n is an integer equal to or greater than 2), n signal transmission lines (GH) connected to N-gate electrodes (d) of the switch thyristors (S) individually, a plurality of light emitting thyristors (T) having N-gate electrodes (b) connected to one of the n signal transmission lines (GH). Anodes (e) of selection thyristors (U) are connected to the N-gate electrodes (d) of the n switch thyristors (S), and N-gate electrodes (f) of the selection thyristors (U) are connected to a common selection signal transmission line (CSL).
