In the field of high-end display panels, OLED displays have unparalleled contrast, and their status cannot be shaken. QLED color expression has made many manufacturers covet. If these two technologies are combined into one, it seems absurd, but Samsung quietly looks like It is impossible to become a reality.
Since 2017, there have been rumors that Samsung wants to return to the OLED TV camp. The return method is QLED+OLED. The technical principle is to use the OLED blue light source to supplement the red and green “hybrid” of QD film into hundreds of millions of colors. .
From the name point of view, QD-OLED is more like a combination of quantum dots and OLEDs. Using blue OLED as the light source, a layer of quantum dot QD film is placed on the upper layer, and the corresponding blue pixels directly pass through the blue light, while the red and Green pixels are actually red and green quantum dots that, when exposed to blue light, excite red and green light. Thereby achieving full color.
Because QD-OLED only needs blue OLED light source, it will reduce the cost compared with RGB OLED, and effectively improve the quantum efficiency of red and green quantum dots, close to 100%, which means that the screen is more energy efficient, and the brightness is higher. In addition, the self-luminous characteristics of OLED pixel points are retained.
QD-OLED still has a long way from laboratory to commercial
Compared with OLED, QD-OLED combines the high contrast of OLED with the high color gamut of QLED, and there is no hidden danger of burning screen. On QD-OLED, because all the light sources are blue, there will be no A situation in which the loss is different. From the perspective of various indicators, QD-OLED can be said to have completely exploded OLED screen, but whether it can completely replace OLED to become mainstream, the market has the final say.
OLED has already landed in the high-end market and is regarded as the benchmark for high-end TV and display technology. LG has brought together brand manufacturers such as Changhong and Hisense to launch an attack on the mainstream market through price reduction, and has begun to approach the public's psychological price and occupy the market. Most of the dominant position.
In contrast, Samsung has produced 55-inch and 65-inch QD-OLED panels, but it has not yet entered commercialization due to color tuning and yield problems. Advancing the popularity of QD-OLED and replacing the status of OLED panels will undoubtedly help to get rid of LG Display's dependence on large-size OLED panels, but don't forget that in the small-size OLED market, Samsung has 95% market share and huge profits. In the face of this, there is a need for a more convincing reason to accelerate the business of QD-OLED. However, if QD-OLED can be commercialized, it is undoubtedly the most favorable competitor of OLED technology.
