Speaking of OLED, what is your first reaction?
Burn-in screen? Strobe? Short lifespan?
However, higher contrast, thinner screens, better color display and darkfield performance have also made OLED screens a new favorite of major mobile phone and laptop manufacturers. Many TV and monitor manufacturers have also pushed away OLED products.
But the call for "LCD never to be a slave" is still incessant, so can OLED not be better? It's not impossible, so there's QD-OLED.
What is this QD-OLED, then our story today, hey, still have to start from such a small white dot.
This is a small white dot emitted on your screen, which can be roughly divided into two routes according to the different principles of screen lighting. One is the LCD commonly used for computer screens, and the other is olED that is more used for mobile phone screens.
LCD screen is sandwiched between two pieces of "glass" a liquid crystal layer, the lower substrate placed a thin film transistor, the upper substrate placed a color filter layer, when the LED backlight through the color filter layer will produce different colors, its basic principle is similar to RGB subtraction method.
Compared with the light emitting method of the LCD separating the light source layer and the display layer, the OLED display layer and the light source layer are directly combined into one, and each pixel is composed of an organic light-emitting diode, and then the RGB sub-pixels of different brightness constitute different colors.
OLED has better contrast, darkfield performance, and color performance than LCD screens, but OLED pixels are susceptible to aging, especially when high brightness requires greater current. In order to extend the service life of the display, OLED is not as bright as lcd for a long time. And in order to achieve a combination of colors, RGB subpixels can not fully utilize the highest brightness. To that end, MIT-incubated nanotechnology company QD Vision Inc. has developed QD-OLED, designed specifically for consumer electronics. QD is quantum dot technology, or nanoscale semiconductor structures, that convert the energy received by electrons into visible light.
Using the blue OLED material as the basis for each pixel, every three blue OLED pixels make up a complete pixel. Where did the red and green go? The secret is quantum dot technology, which uses the energy of a blue light source to convert into red and green light.
Since quantum dots are very energy efficient, there is almost no luminance loss in color conversion. Not only effectively reduce the cost and complexity of the traditional RGB OLED screen, but also to avoid the brightness loss caused by the color filter layer, while retaining the advantages of OLED high color gamut, effectively improve the peak brightness, but QD-OLED in the end or use OLED as the main light source, the typical brightness can not be said to reach a particularly high value.
And this alien AW3423DW actually has a peak brightness of up to 1000nit, which makes me feel very Amazing, in addition, 175Hz high brush with ultra-low response time.
As the only OLED display equipped with G-Sync Ultimate, I was fascinated by the dazzling parameters of the alien AW3423DW.
Is it rated on the Internet as high as Wallace QD-OLED is really as smart as legend? So, the emptiness pulled back from the outside, so that we could feel how the actual experience was.
