When selecting or replacing an LCD, engineers often compare screen size, resolution, interface, and connector type first.
But one detail can determine whether the display can actually work with the existing system: The LCD FPC pinout.
Two displays can have the same screen size, resolution, interface, and even the same 40-pin connector, while using different pin assignments.

Why can an LCD display look normal to the naked eye but become dark through polarized sunglasses? This guide explains how LCD polarizers interact with polarized lenses, why display orientation matters, and how to evaluate polarization compatibility for outdoor and industrial displays.

An In-Cell display integrates touch-sensing functionality into the display cell instead of using a separate touch-sensing panel. This changes the architecture of the display module and allows display and touch functions to be integrated more closely. But In-Cell should not be treated as a standalone performance specification. The final result depends on the interaction between the display cell, touch-sensing structure, touch controller, cover glass, optical stack, FPC, interfaces, mechanical design, and operating environment.

The FPC, or Flexible Printed Circuit, carries electrical signals between the display and the system electronics while also fitting into the mechanical space around the display. When the standard FPC does not match the required cable length, routing direction, pinout, connector, or installation space, a custom FPC may be needed.
For industrial and embedded display applications, FPC design is therefore part of the display integration process—not simply a matter of adding a flexible cable.

When selecting an IP-rated display, it is easy to assume that a higher number always means better protection. In practice, IP65, IP66, IP67, IP68, and IP69K address different types of exposure to water, and one rating does not automatically replace another.
This guide explains the differences between IP65, IP66, IP67, IP68, and IP69K, including what each rating is tested for, where it is typically used, and what an IP rating does—and does not—tell you about an industrial display.

To address these challenges, manufacturers apply different cover glass surface treatments. Among the most common are AR (Anti-Reflective), AG (Anti-Glare), and AF (Anti-Fingerprint). Although these treatments are often mentioned together, they solve different problems and are based on different manufacturing technologies. In many industrial applications, they are combined to achieve the best overall optical performance.

In this article, we'll examine where display power consumption comes from, which design choices have the greatest impact, and practical engineering strategies for building more energy-efficient LCD systems.

This guide explains the relationships between LCD screen size, display resolution, and aspect ratio, compares the most common display formats, and provides practical recommendations for selecting an industrial LCD display.

This guide explains how engineers evaluate capacitive touch controller ICs, which technical factors influence controller selection, and why the best solution is determined by project requirements rather than controller brand alone.
