Display Technology

In industrial, medical, and outdoor equipment, insufficient LCD brightness is one of the most common—and most critical—pain points. Low brightness does not just affect visual comfort; under direct sunlight, the screen may become completely unreadable, rendering the device ineffective.

In industrial and embedded systems, LCD selection is rarely about “which looks better.”
Yet many decisions are still influenced by consumer-market assumptions—especially when comparing TN (Twisted Nematic) and IPS (In-Plane Switching) LCD technologies.
This article addresses common myths surrounding TN and IPS displays in industrial applications, and explains how engineers should evaluate them based on real system requirements rather than marketing narratives.

IntroductionHave you ever wondered how the small screen on your device works seamlessly with the rest of the technology? Embedded displays are the unsung heroes in modern electronics. These systems are integral to everything, from smartphones to complex industrial machines.

In the world of industrial and commercial displays, resolution plays a critical role in determining image clarity, readability, and overall user experience. Among various display resolutions, 1280 x 720—commonly known as HD—remains a relevant choice even in an era dominated by Full HD and 4K screens. But why does 720p still matter for certain applications?

Image retention—also known as image persistence or image sticking—is a common concern in industrial LCD displays, especially in applications where static images are shown for long periods. Although LCD technology does not suffer from permanent burn-in like OLED, image retention can still affect display uniformity, readability, and perceived quality if not properly addressed.

Understand display serial interfaces, including SPI, LVDS, MIPI DSI, and eDP. Compare bandwidth, cost, distance, and use cases to choose the right interface for industrial and embedded displays.

Have you ever wondered how devices like smartphones or industrial machines display real-time information seamlessly? The answer lies in embedded displays. Unlike traditional monitors, these displays are integrated directly into the device, playing a vital role in the overall functionality.

For industrial, automotive, medical, and outdoor applications, screen readability under sunlight is critical. Unlike consumer devices, industrial displays often operate in harsh ambient light conditions, where insufficient brightness can compromise visibility and usability. Understanding nits, sunlight-readable displays, and brightness requirements is essential for selecting the right display solution.

In this article, we will explore the longevity of TFT displays, the factors that influence their lifespan, how to maximize their durability, and what to expect from TFT technology in terms of longevity. By the end, you'll have a clear understanding of how long you can expect your TFT display to function at its best and how to extend its useful life.

At FANNAL, we are often asked about the difference between LCD and OLED displays. Many people are familiar with OLED screens in smartphones and TVs. Still, when it comes to industrial, medical, outdoor, or embedded applications, the answer is not as simple as “OLED is better.” In this article, we explain the real technical differences between LCD and OLED displays, based on our experience as a custom display manufacturer, and help you choose the right technology for your project.
