The progress of technology and the improvement of production will always bring some good things with high prices to the mainstream market, come to the front of more small partners, in the recent and future display market, everyone looks forward to the "good things" must have OLED and mini LED two panel products. Has long been available, in mobile devices has been very common "old aristocrat" OLED and "upstart" mini LED in the end what is the difference? Who should we choose? Let's talk a little bit about it.
A small partner who is using a mobile phone to read WeChat, maybe what you are looking at is an OLED screen. It is particularly popular with mobile phone manufacturers because of its unique advantage, that is, pixel self-illumination, compared with the rear backlight, by blocking the light to present the color of the traditional liquid crystal, the highest brightness and contrast (the brightest and darkest contrast) is much better, the same technical level, the color is more vivid, and the same brightness and other parameters are relatively power-saving, and because there is no backlight layer, so it is thinner.
OLED uses electric current to directly excite the color substances in the pixel to emit light and produce colors, which also poses a problem, that is, the consumption of these substances. If you maintain the color of a certain pixel for a long time, you may over-consume these substances, resulting in a decrease in the ability to emit color and luminescence, and the perception is that the color of this pixel or even all the colors and brightness are gradually dimmed, if it is a piece of pixel problem, it is the so-called "burning screen".
As for the mini LED, although it looks updated, it is more "conservative" in technology, to put it bluntly, it is to turn the original unified brightness backlight into a partition to adjust the brightness, of course, the premise is to use LED light dot matrix backlight. Now the common mini LED will be divided into 512 to thousands of backlight partitions, each partition is about tens of × dozens of pixels of the area, with lcd control, you can adjust the pixel brightness faster and better, the same can present more vivid colors and better contrast.
However, it also has an unavoidable problem, that is, a small number of pixels with large brightness differences in a certain partition, such as when viewing the starry sky. If the brightness of the partition is lowered according to the color of the sky at night, then the starlight is too dim and distorted, on the contrary, if the brightness of the star is guaranteed and the brightness of the backlight partition is increased, then the surrounding dark pixels are likely to be illuminated, resulting in the so-called glow, and the base color of the starry sky is distorted.
A simple look at the characteristics of the two products, in fact, their most suitable scenarios can also have a basic understanding, such as more inclined to fixed scenes, such as always use a software, an interface for a long time to work, design, reading, you must pay attention to the fixed display area OLED burn-in problem, mini LED is more appropriate. If you prefer entertainment, such as games, videos, or a wide range of interests, then OLED with excellent color, high-speed response, and no small area showing "worry" is more suitable for you.
