What is Full-Array Local Dimming, Is It Worth It?

In the realm of digital signage, achieving optimal display quality is paramount. Full-Array Local Dimming (FALD) technology has emerged as a promising solution, enhancing contrast ratios and improving overall visual performance. But what exactly is Full-Array Local Dimming, and is it worth the investment? Let’s delve into the intricacies of this technology to uncover its benefits and determine its value proposition for your digital signage setup. Full-Array Local Dimming is a backlighting technology employed in LED displays, offering superior control over brightness levels and contrast. Unlike traditional LED displays, which utilize edge-lit or direct-lit backlighting, Full-Array Local Dimming divides the LED backlight into zones, each independently adjustable to dynamically control brightness and darkness in specific areas of the screen. This precision backlighting technique results in deeper blacks, brighter highlights, and enhanced image detail, ultimately delivering a more immersive viewing experience. One of the primary advantages of Full-Array Local Dimming is its ability to enhance contrast ratios significantly. By selectively dimming certain areas of the screen while keeping others illuminated, FALD displays achieve deeper blacks and brighter whites within the same frame, resulting in images that appear more vibrant and lifelike. This improved contrast not only enhances the visual appeal of content but also contributes to better image clarity, especially in low-light environments. Furthermore, Full-Array Local Dimming minimizes the phenomenon of backlight bleeding, commonly observed in traditional LED displays. With precise control over backlight zones, FALD technology reduces light leakage, ensuring uniform brightness across the screen and eliminating distracting halo effects

Technical progress in LCD splicing screen size and seam

From the demand of the commercial display market, LCD splicing screens are subject to more competition in the fields of education, security, engineering, digital signage, etc. Therefore, while the technology is highlighted, the LCD display is meticulously crafted and can break the small The size of the application is limited, focusing on the LCD splicing display products to achieve a “seamless” display effect in the splicing gap, as well as the further large-scale and diversified size, and the technical experience of high-definition highlight display. The LCD splicing screen is composed of multiple unit screens. Each splicing unit has a long life and low radiation to support its stable performance to support it. Different processing systems can be selected according to the user’s requirements for input signals. Supported by the application of emerging technologies, it can smoothly access massive signal sources and receive remote signals, which is conducive to the free switching of various signals through the control software, splicing into full-screen display, arbitrary combination display, image roaming and superimposing display, etc. , Such as can make it fully cope with the multi-faceted display system application of remote data roaming monitoring in the security field. It is enough to witness that such an ultra-high application solution can create personalized use for users on different occasions, and meet the needs of big data computing in the new era! The application of LCD splicing screen display is based on its excellent advantages in terms of diversified display methods and carrying massive signal reception

What are the basic components of LCD?

We will use some electronic devices in our life, LCD module is one of the electronic components. Everyone’s understanding of it must be relatively strange, and then we will talk about the knowledge in this respect.   The following is an introduction to the three basic components and features of LCD. Let’s take a look with the editor: Liquid Crystal Materials Liquid crystal material is the main body of liquid crystal display. Different devices use different liquid crystal materials. Most liquid crystal materials are composed of several or even more than ten kinds of single liquid crystal materials.   Polarizer The light sheet, also known as polarized light, is made of plastic film material, coated with a layer of optical pressure sensitive adhesive, which can be pasted on the surface of the liquid crystal cell. There is a protective film on the surface of the front polarizer, which should be removed when using. The polarizer is afraid of high temperature and high humidity, which will depolarize or blister under high temperature or high humidity conditions.   Glass Substrate A kind of float production thin glass sheet with extremely flat surface, the surface of which is evaporated with a layer of zn203 or sn02 transparent conductive layer, i.e. ITO film, is processed into transparent conductive pattern. If scratched, cut or corroded, the vacuum device will be scrapped.
