Televisions now go into thousands of homes and become a designer for the living room, without which the living room is incomplete, while early televisions are still in the cathedral, with a square face, big ass, often with snowflakes. Video tube television has long been the eternal memory of that generation, and now it's all liquid crystals, leds, but now it's a lot of tv, what 4k, 8k, lcd, led, old, plasma tv, which is so dazzling that it's not clear that it suits itself. Today we are going to talk about the difference between these televisions。
Lcd, lcd, lcd, lcd
Lcd tv, a landmark product after vic tv, had early weaknesses such as the high price of lcd panels, low colour saturation and relatively short life of lcds, which were now overcome with low lcd tv power, low fashion, clear images, high contrasts, and good dynamics, all of which prevailed over vc tv. The first lcd display equipment was manufactured by sharp in japan in the early 1970s, and lcd is a substance in solid and liquid form. Lcd tv is inside a liquid crystal between two glasses, adding voltage, reproducing the image by molecular sequencing changes and twist changes, and the screens are created through the collision of electronic clusters, creating images and creating images through in-depth reflections of back-light sources. The backlights are different, divided into lcds (fluorescent lamps) and leds (leds) backlights, known as lcd lcds and leds, which are in fact lcd panels, which are both lcds, which are smaller, smaller in size, have relatively better colours and are more expensive. Most of the backlights are now leds, because they can be super thin, more visible, but they are lcds。
Qled (quantities point), the difference between old tv
Qled is called quantum dot light emitting diode, short of quantum dot lighted secondary. Theoretically, this quantum-point technology can improve key image quality indicators and the black purity of led monitors. Qled television also uses lcd panels, led lamps for backlight sources, so it is the upgrading of traditional lcd television. Oled is known as organic light-emitting diode, or organic light diodes, which operate on the basis that these olds, consisting of organic compounds, are luminescenced during electrical power and are free to open and shut down pixels. Oled television screens require millions or even millions of such oleds to complete a full picture. Oled has lower energy consumption, better colour and response time than qled, but oled has a low yield and high price, and now has relatively few large market-size old television products, and qled television has a considerable advantage in brightness. Led television is already very bright, but quantum point technology can further increase the brightness and hdr is better. At present, lg, sengwei, rainbow, sony, sony, matsuna, tp-vision are old television producers. The qled alliance, led by samsung, has haishin and tcl manufacturers。
4k and 8k tv
4k and 8k refer to the resolution, the precision of the screen image and the amount of pixels that the monitor can display. The more pixels the monitor can display, the more fine and clear the picture. The more real you see. 4k television refers to ultra-high-resolution television with a screen resolution of 3840 x 2160 and above, which is eight times the resolution of high-resolution and four times the resolution of high-resolution. The imax screen, now widely used in cinemas, is one of the 4k resolution applications. When 4k technology became widespread, jvc and nhk jointly launched 8k resolution. This technique is even more exaggerated, with a resolution of 7680 x 4320 pixels, which is 16 times greater than the current mainstream high-resolution television and four times more than 4k television. If you look at the big blues on 8k tv, it's only 1/16 on the screen, but now there's very little tv signal for 4k, not to mention 8k, so it's usually a low resolution, just a shopkeeper's point of sale。
Twilight tv, smart tv
The wider angle of viewing on the curvature of the human eye, which is consistent with the physical structure of the human eye, reduces the sense of visual and eye fatigue, but it is expensive and more expensive to maintain, so that users do not choose to use it, smart television, which now has a master board, which can be made into a microcomputer, allowing for voice recognition, language awakening and offline, etc., which depends on the needs of each person and is also a selling point for the factory。
In the end, the mainstream is the led backlighted lcd television, which meets the needs of most users. Apart from language recognition, smart tv is not as smart, curve screens are just good, 4k and 8k tv signals are not supportive, old and qled look at your consumer skills, and if they find it expensive, they can do it。
