What is the difference between OLED TVs and LCD TVs?
Although many people seem to have a clear understanding of the difference between LCD and OLED technologies, the difference between these two technologies is not as simple as imagined. Considering that more and more people are still entangled in whether to buy OLED or LCD, today the author will analyze one by one from 1. thinness, 2. color, 3. black performance, 4. response time, 5. HDR effect, 6. visual angle, 7. price and other technical dimensions, the purpose is to let everyone really understand what their needs are, and make the most suitable decision when purchasing.
OLED displays have obvious advantages in thinness and black field performance
What is the difference between LCD and OLED?
First of all, we need to know that LCD and OLED are two completely different display technologies. There are essential differences between the two in the principle of luminescence, and these "innate" differences lead to the two types of TV products "complementing each other".
In a literal sense, LCD (Liquid Crystal Display) is "liquid crystal display" technology, LCD TV is what we often call LCD TV, is a liquid crystal display technology TV that uses LED (light-emitting diode) as the backlight light source.
The self-luminous properties that come with OLEDs
OLED (Organic Light-Emitting Diode), literally understood as "organic light-emitting diode", the biggest difference between it and LCD is that it has the property of "self-illumination", and the components of organic light-emitting semiconductors can "emit light on their own" and do not need the support of "backlight".
Taken literally, many people may still not understand what "self-luminescence" means? How is OLED technology implemented? It doesn't matter, some insiders have made a very vivid analogy for the difference between OLED and LCD: "OLED and LCD, one is like the sun, and the other is like the moon." ”
Structure and principle of liquid crystal technology (LCD) technology that relies on backlight system operation
Of course, OLED is the sun, and because all stars are "self-luminous," it's bright no matter which angle you look at.
LCD is more like the moon, because the planet itself does not emit light, needs an auxiliary light source, and reflects the refracted light to emit light; The light source of the LCD is the backlight panel behind the screen, which illuminates the display by refraction and reflection.
The streamlined module architecture makes OLED have obvious advantages in terms of thinness and lightness
OLED display technology does not require a backlight, eliminating liquid crystals and backlight modules to be thinner
Compared with liquid crystal technology with complex structure, OLED display technology does not need backlight support, so it eliminates the need for liquid crystal and backlight modules, the structure is very simple, and the fuselage can naturally reach the ultimate ultra-thin, which can probably achieve 1/3 of the thickness of traditional LCD. The thinnest wallpaper TV in the world comes from the LG W7 OLED TV, which is only 2.57mm thick.
The world's thinnest wallpaper TV, currently only OLED display technology can be achieved, 2.57mm thickness is enough to make people jaw-dropping. In addition to being thinner and lighter, OLED display technology also has advantages in product form.
