The color TV market is changing with each passing day, and the partners are often confused by various technical terms. Today, Xiaobian will help you with the difference between O LED & QLED, and hope to give you a little help when choosing TV!
CES2015, the world's largest IT exhibition, came to an end some time ago. At CES2015, LG Electronics still displayed innovative and strategic products such as OLED TVs with different sizes and designs, and ULTRA HD TVs and G FLEX 2 with quantum dot backlight technology.
At this CES exhibition, QLED (Quantum Point Technology) TV has received wide attention. The competition companies such as Korea, China and Japan all use QLED (Quantum Point Technology) TV as their main product intention, and launched QLED (Quantum Point Technology) TV to replace OLED TV to launch sales strategy. Can it really be replaced? In response to the LG Display president Han Shangfan at the CES2015 press conference, "OLED TV and QLED (quantum dot technology) TV are fundamentally different." OLED TV is a new generation of display technology, completely not a liquid crystal TV, and QLED (quantum dot technology) TV is an improvement of LCD LCD TV.
So what is the technology of QLED? Let LG Display explain the difference between OLED and Q LED technology in detail!
QLED (Quantum Point Technology) TV is also called quantum dot LCD TV. It uses the purest color quantum point light source as the backlight source. It revolutionizes the full color gamut display and restores the image color most realistically.
Quantum dots are small-sized spherical-shaped semiconductor particles of nanometer size. When a voltage is applied, self-luminescence is generated, and light of the same wavelength is absorbed and re-released.
QLED (Quantum Point Technology) TV is also called the final evolution of LCD TV. It also uses liquid crystal technology panel with backlight to achieve imaging, but the difference with traditional LED TV is that QLED particles are added to the LED backlight. Instead of the YELLOW phosphor, a more pure color can be exhibited.
The OLED display is a display of organic self-luminescence from each pixel of carbon, hydrogen, helium, and yellow. There is no light leakage due to the liquid crystal.
1. OLED TV without design and freedom of light source
The biggest difference between QLED (quantum dot technology) TV based on LCD LCD TV and organic self-illuminating OLED TV is whether there is a backlight. Unlike QLED (Quantum Point Technology) TVs which improve the efficiency of LCD TV backlights, OLED TVs are constructed by adding organic substances to the TFT mechanism without a backlight. After abandoning complex modules such as backlights, OLED TVs are also much better in thickness and weight than QLED (Quantum Point Technology) TVs.
2. No image residue, etc. can reflect the ultimate image quality
The image quality components include design elements such as screen size and BEZEL thickness, and composite elements such as screen brightness (luminance), resolution, brightness contrast, color reproduction rate, and video response speed.
OLED display video response speed is 1 millionth, 1000 times faster than LCD, there is no problem such as afterimage (Blur), with 1/100,000 brightness and dark contrast, than the LCD has a large color reproduction rate (Color Gamut), contrast can It is able to achieve the most realistic and beautiful quality.
3. Is OLED a price that consumers can accept?
70% of LCD LCD TV manufacturing costs are material. Compared with OLED TVs, the cost of materials such as liquid crystal, backlight module, color filter, and polarized light is reduced, and there is an advantage that the potential manufacturing cost is reduced. Although QLED has an advantage in terms of price now. However, the O LED market is growing very fast every year, and the E4 production line of the LG Display Pazhou plant has accelerated the production speed and gradually stabilized the component reduction. It is predicted that OLEDs will also be competitive in terms of consumer prices after 1-2 years.
QLED technology is only an improvement of LCD liquid crystal technology, and it is not a new generation technology. Due to the low technical difficulty, South Korea, even Chinese and Taiwanese companies can use it without a competitive advantage.
However, OLED is a product that is easy to bend, has good flexibility, and can display future display technologies and lead the next generation of display technology. The eutectic temperature of OLEDs is relatively low, and the glass matrix can be replaced by a plastic matrix, which enables a smoother manufacturing display. Plus the need for a backlight, it is rated as the best technology for making transparent displays.
There are many factors for evaluating image quality performance. Contrast, brightness, response speed, field of view, natural primary colors, and more. When these performances are improved, our eyes are LG that can distinguish good image quality. When OLED TVs were first launched, everyone was amazed because consumers experienced the quality of LCD TVs without their eyes. Now LG leads the market with the leading new generation display technology in the OLED TV market. In addition, in the UHD TV field where QLED technology is applied, LG is not willing to show the best products.
At CES2015, the reason why QLED (quantum dot technology) TV is concerned is that the competitive company is only able to choose the LCD TV field because of its technical difficulties in developing OLED TV. At CES2015, we can see the strong technical strength of LG OLED TV, and bravely march on the road of OLED TV development, and the real "Game Changer", we also believe that with LG OLED TV, LG is more competitive To lead the new generation display market.
PVC Keychain/Key Ring introduction:
When we leave home we need keys to lock the door ,when we came back we need keys to open it.We need keys for opening and locking for Cars ,office and table or cabinet!We have many keys in our life ,so we need a keychain to keep them in order ,comparing to silicone keychain ,the PVC keychain is a little harder and not easy to tear off,and its cost is lower than silicone ones,so we can create new designs irregularly in low cost ,this is flexible to make our life more funny !
