Lightweight and portable Conventional displays Because of the use of CRTs, electron beams must be emitted from the electron gun to the screen, so the neck of the picture tube cannot be made very short, and the volume of the entire display must be increased as the screen increases. The liquid crystal display controls the state of the liquid crystal molecules through the electrodes on the display screen to achieve the display purpose. Even if the screen is enlarged, its volume will not increase proportionally (only increasing the size does not increase the thickness, so many products provide a wall hanging function, which allows Users are more space-saving, and they are much lighter than traditional displays with the same display area. LCD TVs weigh about 1/3 of traditional TVs.
Large resolution, high definition The liquid crystal display uses a purely flat glass plate from the beginning, and its flat right angle display looks much better than a conventional display. However, in terms of resolution, liquid crystal displays can theoretically provide higher resolution, but the actual display effect is much worse (there is a problem of optimal resolution), although LCD TVs can overcome the jitter and flicker of the scan line, but Due to the thick gap of the liquid crystal itself, the image will be viewed like a grid. Therefore, the optimal resolution of the LCD screen is generally 1024X768 (sufficient). The traditional display achieves perfect display with the support of a better display card.
The green LCD display has no radiation at all, and only a small amount of electromagnetic waves from the drive circuit can be excluded by strictly sealing the outer casing. Therefore, liquid crystal displays have a so-called cold display or an environmentally friendly display. There is no screen flicker on the LCD TV, which is not easy to cause visual fatigue.
Low power consumption According to industry standards, the use time is 4.5 hours of annual power consumption per day, replacing 32-inch CRT TV with 30-inch LCD TV, saving 71 kilowatts per year per unit.
