Alternative Methods of LCD Control
Multiplexed LCDs have been used for over 30 years, and the methods for driving them are well-known and remained unchanged for the past 20 years. Advancements in LCD materials and a new understanding of density modulation, however, allow for new digital approaches which are scalable with silicon processes and allow for more cost-effective designs. This article will demonstrate a conventional implementation and show two alternative approaches, requiring only digital signals, to drive the LCD.
