摘要 |
a photo diode bias line (14) for applying a voltage to a photo diode for the photo-electric modulation; a plurality of photo diode having a photo diode bias line (14), formed as a double array in both sides so as to perform the photo-electric modulation; a plurality of thin film transistor connected to each photo diode, for switching the electric signals which are photo-electrically modulated from the photo diode; and a matrix line connected to each thin film transistor, for processing a gate address and data.
