Especially for battery-powered devices or applications with a “weak” power supply over bus systems, there is a need for energy-saving display solutions. Besides E-Paper displays and classic passive LCDs, two lesser-known liquid-crystal-based display types, called ULP and MIP, can also be considered for such use cases. In this report, we focus on these two technologies.

There is a confusing variety of different interface types for displays. To help you choose the right interface, we bring some order to this chaos and provide you with an overview and guide below. In this article, we will exclude the control of displays without logic (such as passive LCDs or LED displays without an integrated controller). Controlling these usually requires a specialized driver chip to be placed on the application circuit board.

LCD stands for "Liquid Crystal Display." In today’s world, LCDs are ubiquitous – found in smartphones, computers, televisions, and everyday items like calculators and refrigerators. But how exactly do LCDs work? In this blog post, we take a closer look at their basic functionality.
