What is LCD?
LCD (Liquid Crystal Display) is an image technology based on the principle that it can be polarized by electrical energy and visible to the eye with a polarization filter added in front of it. Liquid crystal is one of the states of matter defined outside of the states we currently know. LCD screens have replaced the fluorescent screens used in the past with their low energy consumption. Although LCDs are superior in contrast, power consumption and image quality, they are also poor in resolution, dot range, response time and viewing angle.

Types of LCD
There are 4 types of LCDs: TN (Twisten Nematic), STN (Super Twisted Nematic), FSTN (Film Compensated Super Twisted Nematic) and CSTN (Color Super Twisted Nematic). After briefly mentioning the LCD types, now let's talk about the Custom Design LCD and the Nuvoton processors to drive these LCDs.
Custom Design LCD
Custom Design LCDs are LCDs designed specifically for an individual, and these LCDs are designed entirely according to the user’s requests. Thanks to this, it is possible to use project-specific LCDs directly, without relying on ready-made molds. The biggest advantage of Custom Design LCDs is their cost. Especially when used in high quantities, the costs can be quite low.
But in order to drive these LCDs, special microcontrollers with LCD Drivers are required. At this point, Nuvoton offers some options.
Nuvoton's 8051 and M0 microcontroller series have microcontrollers that can drive an LCD. These microcontrollers are N76E616 from 8051 series, Nano110/112 LCD Series and Nano130 Advanced Series from M0 series.
