Recently I bought a 128x240 LCD with ts6963c driver chip. The part number is TS240128D-1. I am familiar with KS0108 driver but the problem is different pinouts. I found a good manual in a book for ts6963c and expected a 19 pins module but the module contains 22 pins.Here is the data sheet:TS240128D-1
I dont know what the pins "pin4: VO" , "pin19: VOUT" doing there. Are they connected with a potentiometer to each other and ground as is in ks0108? On the other hand, in page 2 of that data sheet, pin 22 is named "DSPON" (Display ON?) but in top of the next page it is named "NC" (Not Connected?). What is this pin doing? It would be a great help if anyone can answer my question.
