When it comes to display technology, we often focus on the flashy features like 4K resolution, HDR, and high refresh rates. However, there’s a lesser-known aspect that plays a crucial role in our visual comfort: flicker-free technology. In this article, we’ll delve into the world of flicker-free displays, exploring what it is, why it’s important, and how it can impact our viewing experience.
What is Flicker-Free Technology?
Flicker-free technology refers to the ability of a display to produce a stable and consistent image without any noticeable flickering or pulsing. This is achieved by using a variety of techniques, such as DC dimming, PWM (Pulse Width Modulation) dimming, or OLED panels. The goal is to eliminate the flicker that can cause eye strain, headaches, and discomfort.
How Does Flicker-Free Technology Work?
To understand how flicker-free technology works, let’s first look at how traditional displays operate. Most LCD displays use a backlight to illuminate the liquid crystals, which block or allow light to pass through to create images. However, this backlight can flicker, causing the image to pulse or shimmer. Flicker-free technology addresses this issue by using alternative methods to control the backlight or by using display panels that don’t require a backlight.
For example, DC dimming works by adjusting the voltage of the backlight to control its brightness. This approach eliminates the need for PWM dimming, which can cause flicker. OLED panels, on the other hand, don’t require a backlight at all, as each pixel emits its own light. This makes OLED displays inherently flicker-free.
