Almond路由器是如何驱动LCD的？

LCD接口：
并口 ( Parallel LCD Interfacing)
串口 (serial RS-232)
FPGA

LCD interfacing:
LCD are connected to microcontroller through a LCD interface IC or directly to it's address and databus and few control pins, Few of the today's latest microcontrollers have built-in LCD driver.
Also some of the LCDs support serial interface.
Here are few nice articles on LCD interface from the internet and our own module, you can choose based on your interest from the below list of LCD interface articles.
