注:SED1335是 LCD 控制器，并不是LCD显示屏。具有SED1335控制器的LCD屏有很多，比如。LMS 195-F显示模块，AT-320240Q1型液晶显示屏，液晶显示模块LMBGA_032_49CK。英文描述：The SED1335 is a CMOS low-power dot matrix liquid crystal graphic display controller.
The device stores in ... The SED1335 can be interfaced to high-speed microprocessors
such as the Intel family or Motorola family.
