In 2017, smart phone manufacturers are fiercely fighting, and major manufacturers have shown "trick". On the other side of the TV market, although sales in the first half of 2017 have fallen year-on-year, TV manufacturers are still racking their brains and seeking new breakthroughs. With the development of technology and the improvement of people's living standards, consumers' pursuit of television is no longer a simple way to watch programs. Today's color TVs are black technology, chasing beauty and visual enjoyment.
Just a few days ago, the annual Las Vegas International Consumer Electronics Show (CES) was just closed. It is the world's largest technology show, smartphones, tablets, laptops, TVs, smart homes, robots, Drones and high-tech cars abound.
Color TV has always been one of the most popular categories of CES. At this year's show, Samsung Micro LED TV and QLED, Hisense Laser TV, LG and Sony's OLED TV have appeared, these new products are improving the consumer viewing experience. It also lights up the development of color TV technology for the color TV industry: quantum dots, OLED, 8K, artificial intelligence, HDR. A whole new wave of TV technology is coming, they will bring us an unprecedented "visual feast".
This issue of Xiaobian will introduce Samsung QLED TV and LGOLED TV to see which one is more cool and more worthy of getting started.
QLED VS OLEDSamsung QLED TV and LG OLED TV, from the name of the name, know that its display uses different technologies, then, what is the difference between QLED and OLED?
OLED (Organic Light-EmitTIng Diode) is literally translated as an organic light-emitting diode, which has a self-luminous property, and uses a phosphor color layer to generate light of different colors instead of requiring a backlight like a liquid crystal screen.
QLED (Quantum Dots Light EmitTIng Diode Display) is a quantum dot light emitting diode. Unlike the quantum dot backlight technology, it is more like an OLED, which has self-luminous properties, but the self-luminous object is not an organic diode but a quantum dot. Quantum dots have a distinctive property: every time they are stimulated by light or electricity, quantum dots emit colored light. The color of the light is determined by the material and size of the quantum dots. This feature allows the quantum dots to change the light source. The color of the light emitted.

Picture qualitySamsung QLED TV
At present, for quantum dot TV, there is a common problem, that is, too high brightness will dilute the color performance of the picture, which is the main reason for the development of quantum dot technology. In fact, to a large extent, the color is determined by the light, and the different lighting conditions will also affect the brightness and vividness of the color. This is also the meaning of the “color quantityâ€, which is the standard for testing the color expression under different brightness. .
When the amount of color is increased, the TV can display a wider range of colors, from the three primary colors to the achromatic color, which are more vivid and precise. However, if you want to effectively reproduce the amount of color, you need a high brightness, which is back to the high brightness we said earlier will dilute the color performance of the display.
In order to solve this problem, Samsung has used a new "metal quantum dot" technology in QLED displays to effectively improve luminous efficiency. When the brightness is within the peak interval, more light is transmitted from the quantum dots, which effectively increases the amount of color. The increase in brightness makes the picture more lifelike while maintaining color stability.
All along, the biggest advantage of Samsung QLED TV is its color performance. The current technology enables QLED TV to display more than 1 billion colors and restore 100% color volume.
The color rendering volume is an accurate standard for color rendering, measuring a three-dimensional space consisting of the color gamut and brightness levels of a television. The gamut depends on the maximum number of colors that can be physically displayed, while the peak brightness represents the maximum brightness level of the display. The 100% color rendering volume allows the colors presented to be unaffected by the brightness level, and the colors in both bright and dark scenes can be restored to the maximum extent.
From the CES 2018, Samsung's new QLED TV uses a full array of LED backlights and Local Dimming technology to create deeper black and higher brightness, even in dark scenes. Nor will you miss any details. At the same time, the TV screen is also anti-reflective, and it will not affect the performance of the entire screen due to various ambient light. Moreover, thanks to the local light control technology, the halo phenomenon in the picture is effectively eliminated, and the "black and white distinction" is truly achieved.
LG OLED TV
In the field of OLED, LG has an absolute right to speak. As the founder of OLED technology, LG is currently the only manufacturer capable of producing large-size OLED screens, supplying OLED panels to more than 90% of mainstream TV manufacturers such as Sony, Skyworth and Philips.
LG's OLED technology currently supports one billion colorful functions, which can display up to 64 times the color, reach one billion colors, and make the color transition more natural, so the processing details are more delicate. This point is not inferior to Samsung's QLED level.

HDR technologyIn order to improve the overall display of the screen, since 2016, major TV manufacturers have begun to promote HDR technology. The solutions that can currently implement HDR technology are roughly classified into Dolby Vision, HDR10, and HLG. TV manufacturers are more using Dolby Vision and HDR10. The biggest difference between the two is that Dolby Vision adds "dynamic metadata" to the core HDR image data, so that the brightness, contrast, and Information such as color is more accurately read and presented.
Samsung QLED TV supports HDR high dynamic range image technology, which can retain more dark and bright details, plus excellent light control optimization, even if the same picture is displayed at the same time showing extremely dark and bright pictures, it will not appear The details of light leakage or whitening are lost, and the details remain perfect.
LG OLED TV also supports HDR, W7 Sky, E7 Crystal phantom HDR solution is Dolby Vision. LG OLED TV's own active HDR and "dynamic metadata" can be optimized on a scene-by-scene basis, and the TV can display extremely realistic light and shadow effects. Various light and dark contrasts, light intensity gradients and even halo performances can be vividly realized, even reaching nature. The viewing experience.

Sound effectXiaobian learned from the official website of Samsung and LG respectively, Samsung QLED TV did not make any explanation on the sound effect, and LG E7 and LG W7 support Dolby panoramic sound. Dolby Panoramic sounds easily capture every source in the video content while processing sound, supporting up to 128 different sources in the same scene, and 360-degree immersive vividness for your senses Experience.
At this point, LG seems to be better, Dolby Panorama plus Dolby Vision, providing a cinema-like viewing experience.
In recent years, with the development of TV technology, the trend of intelligent TV sets has become more and more obvious, and the pace has become faster and faster, providing users with rich functions because of the use of intelligent operating systems.
LG OLED is equipped with a Web OS system. The system features simple setup, simple discovery, and simple operation. The user can perform operations including click, click, scroll, and the like in a motion remote control manner similar to the Wii game console.
With a dedicated mobile app, users can streamline their operations on the TV. The scrolling card menu that appears on the TV screen can also be operated on a small mobile phone screen. And you can continue to extend from left to right, you can also take a screenshot of the screen being played on the TV at any time through the phone.

Samsung QLED TV chooses TIzen operating system, the whole system is very clean and tidy, interactive operation is simple and easy to understand, you can find all the functions of this TV in the menu interface. In the connected state, the system will push users to high-quality video or APP applications.
Last year, Samsung extended the Smart Hub interface to the main screen of the mobile app for comprehensive content preview through the newly upgraded Smart View APP. Users can select their favorite live TV programs and video on demand services through the Smart View APP on their mobile phones. They can also choose to use mobile devices to receive broadcast reminders for frequently watched programs, such as broadcast time and online notification.

Appearance cableIn fact, from the current point of view, the appearance of TV products in the market is similar, so it is difficult to have a product that can only be deeply rooted in the appearance.
In the previous TV, there were always some messy cables leaking out, which greatly affected the overall beauty of the living room.
Samsung QLED TV and LG OLED have chosen to connect the screen and the sound with a white wire in the cable design. The design is probably based on the fact that most of the homes are white walls, so the pure white and flat design cables can be cleverly integrated into the wall without disturbing the user's line of sight. If you want to show the effect of murals, you can also cover and lay the wallpaper on the connecting line, you can completely hide it, just like a painting on the wall.

screen sizeAlthough QLED is theoretically more suitable for making a large screen. But Samsung's QLED TV screen is also big enough. Available in 55/65/75/88" sizes for different families.
LG OLED TVs are available in 55/60/65//77/86 and other sizes.
thicknessIn terms of thickness, the thickness of Samsung and LG TVs is about the thickness of an iPhone 7 plus, which can be said to be very thin. The LG W7's main feature is "from a TV to a TV", its thickness is thinner than Samsung's QLED TV. But for ordinary families, this level is enough. Of course, this thickness requirement depends on the individual, like a very thin TV consumer, I think you already know how to choose.

priceFor any product, the price can be said to be the most concerned aspect of the people. The following table shows the price of different sizes of Samsung QLED and LG OLED TVs for everyone.
You can see TVs of the same configuration size. Even though QLED TVs theoretically have low production costs, Samsung's QLED TVs are actually more expensive or equivalent to LG OLED TVs, which is in line with Samsung's unwillingness to take a price war. So choose Samsung QLED TV or LG OLED TV, it depends on whether you are holding
