FALD, or Full Array Local Dimming, is a display technology commonly used in LCD (liquid crystal display) televisions and monitors. It refers to a backlighting system that improves the contrast and black levels of the displayed image.
In FALD, the backlight used in LCD screens is divided into several separate zones or regions. Each zone consists of a group of individual LEDs (light-emitting diodes) that can be controlled independently. This allows for more precise control over the brightness and darkness of different parts of the screen.
The main purpose of FALD is to enhance the display quality by dynamically adjusting the backlight intensity in specific parts of the screen. When combined with local dimming algorithms, FALD enables the screen to produce deeper blacks and brighter whites, resulting in an improved contrast ratio.
By selectively dimming or turning off the LEDs in dark areas of the image, FALD helps achieve deep blacks and reduces blooming or halo effects around bright objects. This technology also enhances the overall image quality by providing more accurate color reproduction, improved shadow details, and minimized light bleed.
While FALD can significantly enhance the display quality and viewing experience, it can also have some limitations. For instance, it may produce visible blooming or overly bright zones around high-contrast objects if not implemented correctly. Additionally, FALD can increase the cost and complexity of the display device.
Overall, FALD is an advanced backlighting technology in LCD displays that aids in achieving improved contrast, vibrant colors, and enhanced image quality.
