Just a few days ago, the annual Las Vegas International Consumer Electronics Show (CES) has just closed. It is the world's largest technology show, smartphones, tablets, laptops, televisions, smart homes, robots, Drones and high-tech cars abound.
TVs have always been one of the CES's most closely watched categories. At this year's show, Samsung Micro LED TVs and QLEDs, Hisense Laser TVs, LG and Sony's OLED TVs all unveiled. These new products enhance consumer viewing experiences. , Also for the color TV industry light up the development of color TV technology in the future: quantum dots, OLED, 8K, artificial intelligence, HDR. A whole new wave of TV technology is coming. They will bring us an unprecedented "visual feast".
In this issue, we will introduce Samsung QLED TVs and LG OLED TVs to non-network sections. We will see which ones are more cool and more worthwhile.
QLED VS OLED
Samsung QLED TVs and LG OLED TVs, from the point of view of the name, know that their monitors use different technologies. So, what is the difference between QLEDs and OLEDs?
OLED (Organic Light-Emitting Diode) is an organic light-emitting diode (LED) that has self-light emitting characteristics and uses a phosphor layer to generate light of different colors instead of requiring a backlight like a liquid crystal screen.
Quantum Dots Light Emitting Diode Displays (QLEDs) are quantum dot light emitting diodes. Unlike quantum dot backlight technology, it is more like an OLED and has self-emission characteristics, but self-emissive objects are not organic diodes but quantum dots. Quantum dots have a distinctive characteristic: Whenever they are stimulated by light or electricity, the quantum dots emit colored light. The color of the light is determined by the material and size of the quantum dots. This characteristic makes the quantum dots can change the light source. The color of the light emitted.

Quality
Samsung QLED TV Currently, for QD TVs, there is a common problem, that is, high brightness will dilute the color performance of the screen, which is also the main reason that has bound the development of quantum dot technology. In fact, to a large extent, the color is determined by the light, and different light conditions also affect the color of the light and dark and live performance, which is the meaning of the "color", it is to test the standard of color expression under different brightness .
As the amount of color increases, the TV can exhibit a wider range of colors, from primary colors to achromatic colors, all of which are more vivid and precise. However, if you want to effectively reproduce the color, it requires a very high brightness, which is also back to the high brightness we previously mentioned will dilute the color performance of the display.
In order to solve this problem, Samsung has used a brand-new "metal quantum dot" technology in QLED displays, effectively increasing luminous efficiency. When the brightness is within the peak range, more light is transmitted from the quantum dots, effectively increasing the amount of color. The increase in brightness makes the picture more lifelike while maintaining color stability.
For a long time, the biggest advantage of Samsung QLED TV is its color performance capability. The current technology enables QLED TV to display over 1 billion colors and restore 100% color volume.
The color rendering volume is an accurate standard for color rendering and measures the three-dimensional space formed by the color gamut and brightness levels of the television. The color gamut depends on the maximum number of colors that can physically be displayed, and the peak brightness represents the maximum brightness level of the display. The 100% color rendering volume allows the displayed color to be unaffected by the brightness level, and the colors in both bright and dark scenes can be maximally restored.
From the CES 2018 point of view, Samsung's new QLED TV is the use of a full array of LED backlight and Local Dimming (local control light) technology to create a more profound black and higher brightness, even in dark scenes Never miss any details. At the same time, the TV screen has also undergone anti-reflection processing, and will not affect the entire screen performance due to various types of ambient light. And thanks to the local light control technology, effectively eliminating the halo phenomenon in the screen, truly "black and white."
In the field of OLED, LG has the 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 billions of colorful features, can display up to 64 times the color, reach one billion colors, so that the color transition is more natural, so the more detailed in the details of the screen processing. This is not the same as Samsung's QLED level.

HDR Technology In order to enhance the overall display of the picture, since 2016, major TV manufacturers have begun to push HDR technology. Currently, HDR technology solutions can be roughly divided into Dolby Vision, HDR10, and HLG. TV manufacturers are more adopting the Dolby Vision and HDR10. The biggest difference between the two is that Dolby Vision has added "dynamic metadata" in addition to the core HDR image data, and thus the brightness and contrast in the data. Color and other information for more accurate reading and rendering.
Samsung QLED TV supports HDR high dynamic range image technology, which can retain more details of shadows and highlights. Plus excellent light control optimization, even if the same picture shows both dark and bright images, it will not appear. Loss of light or white detail is lost, and details remain perfect.
LG OLED TV also supports HDR, W7 sky, E7 Mirage several HDR solutions used by Dolby vision. LG OLED TV's own active HDR and "dynamic metadata" can be optimized scene-by-site, TV can show extremely realistic light and shadow effects, a variety of light and shade contrast, gradual change in light intensity and even halo performance are vivid, even can reach the natural The viewing experience.

The sound effects Xiao Bian separately learned from the official website of Samsung and LG, Samsung QLED TV did not make any explanation in the sound effect, and LG E7 and LG W7 support Dolby panoramic sound. Dolby Panorama sound can easily capture every sound source in the video content while processing sound effects, support up to 128 different sound sources in the same scene, and bring 360 degree immersive liveliness to your senses. Experience.
At this point, LG seems to be even better, with Dolby Panorama plus Dolby Vision providing a cinematic viewing experience.
Intelligent System Platform In recent years, with the development of television technology, the tendency of intelligent televisions has become increasingly obvious, and the pace has become faster and faster, providing users with rich functions because of the adoption of intelligent operating systems.
The LG OLED is equipped with a Web OS system. The system is characterized by simple setup, simple discovery, and simple operation. The user can perform operations including click, click, scroll, etc. in a remote control mode similar to the Wii game console.
With a dedicated mobile application, users can simplify the operation on the TV. The scrolling card menu that appears on the TV screen can also be operated on a small mobile phone screen. And can continue to extend from left to right, you can also use the phone to take screenshots of the screen being played on the TV at any time.

Samsung's QLED TV selects the Tizen operating system. The entire system is very clean and tidy. The interactive operation is easy to understand. All functions of this TV can be found in the menu interface. In the networked state, the system will push high-quality video or APP applications to users.
Last year, Samsung extended the Smart Hub operation interface to the main screen of the mobile phone APP to preview comprehensive content through the newly upgraded Smart View APP. Users can select their favorite live television 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 of frequently watched programs, such as broadcast time and on-line notifications.

Cables
In fact, from the current point of view, the appearance of television products in the market is very similar, so it is difficult to have a product that can only be deeply rooted in appearance.
In previous televisions, there was always a mess of cables leaking out, which greatly affected the overall beauty of the living room.
Samsung QLED TV and LG OLED have chosen to use a white wiring to connect the screen and audio in the cable design. This design probably takes into account that most homes are white walls, so pure white and flat design of the connection can be cleverly integrated with the wall, will not interfere with the user's line of sight. If you want to show the effect of a mural, you can also cover and lay down the wallpaper on the connection line, and you can hide it completely like a picture on a wall.

screen size
Although QLED is theoretically more suitable for making a big screen. But Samsung's QLED TV screen is also large enough. There are 55/65/75/88 inch sizes available for different families.
LG OLED TVs are also available in 55/60/65//77/86 sizes.
thickness
In terms of thickness, the thickness of Samsung and LG TVs is about the thickness of an iPhone 7 plus. It can be said that it is very thin and light. The LG W7 features a "from a TV to a TV," which is thinner than Samsung's QLED TV. But for ordinary families, this level is enough. Of course, this requirement for thickness depends on the individual, who likes very thin TV consumers. I think you already know what to choose.

price
For any product, the price can be said to be one of the most concerned about people. The following table is the price of Samsung QLED and LG OLED TVs of different sizes compiled by Xiaobian.
Can see the same configuration size of the TV, even if the QLED TV theoretically low production costs, but in fact Samsung's QLED TV prices higher than or equal to LG OLED TV, can be considered in line with Samsung's reluctance to go price war style. So whether to choose Samsung QLED TV or LG OLED TV depends on whether you are clinging to the kind of black level performance of OLED, and whether you can accept Samsung's favorite surface design and your own trust in Samsung or LG brand. .
Reviews
For a consumer product, I am afraid that only people who have used it have the most say.

From the comments of users, Samsung QLED TV LG OLED TV has a high degree of praise. Samsung QLED TV and LG OLED TV are better than others. I am afraid there is no answer to this question. Judging from all aspects, regardless of the technology used, its performance varies according to the product. In fact, Samsung believes QLEDs are superior to OLEDs. The main focus is still on panel life, capacity, and cost.
Although these two products are not perfect, but all have their own characteristics, there is no major shortcomings, Xiao Bian suggested that according to their own preferences (such as thickness, Dolby effect, etc.) choose it!
Nowadays there is a saying that TV technology continues to develop and the quality of the picture is no longer the focus of attention. Because for the vast majority of buyers, the quality of high-end TV is good enough. Now. Future TV makers will focus more on features and design. The new products introduced by major manufacturers this year have actually begun to take this route.

New Arrival or New Style Lio Nano Disposable ecig have a completely enclosed design, reducing the need for charging and replacing cartridges. The no-charge design also reduces the occurrence of faults. It is understood that with rechargeable e-cigarettes, each cartridge needs to be charged at least once and the battery efficiency is extremely low, while the design of disposable ecig can solve this problem very well.
