22.1.1 Features
22.1.2 Configuration of the LCD Drivers
The LCD drivers are applicable to various types of LCD panels.
The programmable display allocation function facilitates software display processing. By using “ALL LCDs on mode” and
“ALL LCDs off mode”, LCD panel inspection processing software can be easily created.
Figure 22-4 shows the configuration of the LCD drivers and the bias generation circuit.
