I believe this home isolation has given everyone a deep understanding of how important it is to have a TV with a large screen, good display, and healthy eye protection. Now that production has resumed, the 5.1 holiday promotion is the first in the opening year of major industries. Taking advantage of good discounts, adding a TV to your home is a very good choice. Today, let ’s briefly talk about how far OLED technology has developed and which OLED TVs are worth buying. Well, no more nonsense, let's drive.
The difference between OLED and LCD
OLED and LCD have different lighting methods
LCD screen-Liquid crystal is a type of organic compound between solid and liquid. Under normal temperature conditions, it exhibits both liquid fluidity and optical anisotropy of crystals. It becomes transparent liquid upon heating and becomes crystal after cooling. The turbid solid state, the liquid crystal itself cannot emit light. The working principle of the liquid crystal screen is to change the state of the liquid crystal by the action of the electric field, and then display the picture on the liquid crystal on the screen through the backlight panel. Backlight sources often use LED backlight panels, which is why many people call LCD TVs LED TVs, but its scientific name should be "LCD TVs with LEDs as light sources", or "LCD TVs with LEDs as backlights."
The full name of OLED is Organic Light-Emitting Diode, which translates to organic light-emitting diodes. In other words, the pixels themselves emit light. When voltage is applied to OLED, red light will be generated according to different material characteristics The three primary colors of green, green and blue constitute the basic color, while the other colors are composed of pixels of the three primary colors according to different proportions. The characteristic of OLED is self-luminous, unlike thin-film transistor liquid crystal display that requires backlight, so visibility and brightness are high, and there is no problem with viewing angle, followed by low driving voltage and high power saving efficiency, plus fast response, light weight and thickness Thin and simple in structure can be said to be the major trend of TV development in the future.
OLED does not leak light
The 4K OLED on the left and the 8K LCD on the right. It can be clearly seen that the OLED TV is completely free of any "light leakage" phenomenon. After all, OLED directly controls the light-emitting diodes. There is no backlight light source, so there is no possibility of any light leakage. On the right side of the LCD TV, the bottom of the bubble can clearly feel the black is consistent with other places. This is caused by light leakage. Even the old brands such as LG ca n’t achieve complete light leakage in the quality control of the LCD panel, let alone The LCD screens produced by the second- and third-tier brands are now available.
OLED has higher contrast, black is more pure, and dark details are better
As mentioned earlier, the OLED screen itself has no backlight, so as long as the pixels are turned off, it can show pure black, not only without the hidden danger of light leakage, but also to provide a contrast ratio far beyond the LCD screen.
