For LCD TVs, the screen represents more than half of the total cost of the device. At the same time, it's also one of the most delicate parts of the TV. On the surface, the LCD screen may look like a solid black panel, but in reality, it has a special coating applied to its surface. This coating serves two main purposes: it reduces glare and reflections from ambient light, and it enhances the contrast and color accuracy of the display. Because of this, it's crucial to handle the screen with care when cleaning.
There are two common types of smudges on LCD screens: one is dust that accumulates over time, especially in dusty environments, and the other comes from fingerprints or oils left behind by users. It’s important to avoid using water for cleaning, as moisture can seep into the TV and cause internal damage, such as short circuits. Similarly, regular soft cloths like microfiber glasses wipes or paper towels should be avoided, as they might be too rough and could scratch the sensitive screen.
Chemical solvents, such as alcohol or ammonia-based cleaners, are also not recommended. These substances can strip away the protective coating on the screen, leading to permanent damage and reduced visual quality. Even small amounts of harsh chemicals can have a devastating effect on the screen's performance.
When it comes to daily cleaning, the best approach is to use a dedicated LCD cleaning cloth and a small amount of ion-free water. Gently mist the cloth (not the screen) with water, then wipe the screen in a circular motion. This method effectively removes dirt without scratching the surface. The special fibers used in LCD cleaning cloths are designed to be gentle yet effective, and many also help reduce static buildup, making them far superior to regular cloths.
It’s also important to avoid scrubbing the screen every day. Frequent and aggressive cleaning can lead to tiny scratches or wear on the coating over time. Instead, clean only when necessary, and always use the right tools and techniques. Taking these precautions will help maintain the clarity and longevity of your LCD TV screen.
Other Steel Structures
Steel Structures can be used in many industries such as foundation reinforce, electric power transmission structures and tubular scaffolding, etc.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
