Lenovo smart TV K3 positioning high-end urban population, the functional configuration is Lenovo this year's highest level of smart TV, its biggest feature is the panel is only 7.9mm thin. Let's take a look at the 55-inch version of this new product.

Lenovo smart TV K3 design:

Lenovo smart TV K3's overall color using a relatively calm black, its front design is simple, 3.5mm ultra-narrow frame above no one button, very well hidden screws, cooling holes and other components that affect the appearance of one, can be compared It's easy to integrate with the interior home style.







The side frame of Lenovo smart TV K3 uses metal plating effect (in fact, the interior is still plastic material), but its panel is only 7.9mm thin, giving a great visual impact. The bottom is printed with Legend LOGO alloy trim. The K3's ultra-narrow, ultra-narrow frame echoes the two-point support base of the metallic paint. The K3 makes it look very impressive at a glance.







Most of the backs of Lenovo smart TV K3 are reinforced ribs, which can effectively protect the main circuit boards on the back. And its main cooling holes are also on the back, but there are some problems in the design. The cooling holes are designed to be at a certain angle to the horizontal plane, which makes it easy for dust to enter the interior of the TV. It will accumulate a certain amount of dust when used for a long time. Incidentally, the cooling holes of the Xiaomi TV are designed at the bottom of the fuselage.



The screen, Lenovo smart TV K3 uses LG original imported 4 color 4K IPS hard screen LCD panel, with 38402160 resolution, 2mm ultra-thin light guide plate and only 3.5mm ultra-narrow frame.

4-color means that a single pixel consists of four sub-pixels of WRGB (white, red, green, and blue). Traditionally, we can also call a “4k” TV as a “3 color 4k” TV. It consists of only three sub-pixels of RGB (red, green, and blue). The advantage of 4-color 4K vs. 3-color 4K is that it adds white sub-pixels, which can make the colors more abundant; the light transmittance is increased by 60%, and is brighter and more transparent.

K3 is very good both in terms of color performance and visual impact to users. And its viewing angle has reached 45 degrees, normal viewing TV will not appear color shift phenomenon.

Lenovo smart TV K3 hardware configuration:

In terms of hardware configuration, the Lenovo smart TV K3 uses the MTK5508 solution, which is a dual-core Cortex A17 processor. According to Lenovo officials, it is expected to achieve 60% faster speed and 40% energy savings than the quad-core A9. Built-in quad-core Mali-450 GPU with twice the performance of the previous generation of display chips. The overall system UI runs very smoothly and also supports H.265 decoding, which can save 50% of bandwidth. At the same time built-in 8G eMMC+2G DDR3 storage and USB3.0 high-speed transmission interface, also supports the expansion of the largest 32GB SD card, ensuring excellent data exchange capabilities.

K3 Smart TV supports built-in network cable connection or wireless connection in two ways: wired network supports Ethernet 10/100M Ethernet; wireless network supports WiFi 802.11 b/g/n dual antenna design. By optimizing the antenna design, high-speed data transmission is ensured regardless of the direction of the router in the TV, even if the router and the TV are in different rooms.





In terms of interfaces, K3 fully meets the user's requirements, and has terminals such as HDMI, USB, component, composite video, headphone, network, ATV, DTMB, and SD cards, which can be connected to set-top boxes, DVDs, Blu-ray players, computers, stereos, and game consoles. And other equipment. Only some of the connectors are located in the bottom recess of the back panel, and the plug connection cable is a little inconvenient.

HDMI 2.0 does not use new data lines and interfaces, so it can maintain backward compatibility with the HDMI 1.x standard.

Lenovo smart TV K3 air mouse control:

The Lenovo smart TV K3 uses the iconic "air mouse" remote control of the Lenovo smart TV, but it is not so much a remote controller as it is a powerful mouse.

Simultaneously integrate high-sensitivity omnidirectional microphones, 3-axis gyroscopes and 3-axis accelerometers. Voice, somatosensory and other control functions.





The air mouse surface is divided into two parts, the black key area and the fabric texture hand-held area. The surface of the button area is pure black. There are function buttons commonly used by the user, and there is a voice control button at the bottom. The user can directly press and hold the voice button under any interface of the TV, and the voice command is given to the microphone of the air mouse, which is very convenient. .





The biggest highlight of Air Rat is its new TV interactive control, which projects a mouse pointer-like control on the TV screen. Compared to other smart TVs that require a step-by-step button operation with a remote controller, an air mouse can be located as freely as a computer mouse. Originally, multi-step operations can be performed in one step, eliminating the user's trouble.

Lenovo smart TV K3 system interface:

In terms of software, Lenovo smart TV K3 adopts a UI interface based on Ali YunOS for deep optimization, and continues the sandwich UI structure of Lenovo TV; the first screen interface of TV is divided into three independent interfaces by content, which are: live TV, video on demand.

Through pre-loading technology, point-to-point video can be played, combined with functions such as pause buffer, slice header, breakpoint resume, stream adaptation, etc., to better enhance the VOD viewing experience. However, in the actual experience, the K3 still needs a certain amount of time during the video loading process, although it is reduced compared to other smart TV/box products.



In addition to manually searching for video content, users can also search by voice directly. Just say you want to see the name of the movie, such as "play movie priest down the mountain" and so on. K3's voice search integrates the latest DNN deep neural network technology with the name error correction technology, so the recognition is more accurate. At the same time, it also provides a number of functional services such as weather, tickets, and calculations.



The Lenovo smart TV K3 has a unique air mouse, so there are a large number of games that are suitable for air mouse operation in the app store, so there will be a similar sense of use. We have downloaded a small game named “Jinju Fishing”. There will be various instructions on how to operate the user. It can be quickly grasped and it is very simple. The operation of the air mouse will bring the user a different gaming experience.

To use this mode, some settings need to be made. The user has to input some basic information about the baby, such as gender, age, duration of watching, content screening, and response after the viewing time has arrived. After entering Tiger Mode, the screen will automatically switch to eye protection mode to protect children's vision by reducing the effect of blue light on the macular area of ​​the child's retina, eliminating the flickering of the screen and adjusting the brightness of the screen.





In this mode also has a wealth of resources, including video and even learning resources, children can choose. The above-mentioned voice search function is also applicable in this mode, and the voice search range at this time is the internal resources of “tiger mother”, so as to prevent children from accidentally touching and jumping to other contents. And in Tiger Mode, there is a green “thermometer” in the upper right corner of the screen as a watch duration timer, which is convenient for parents to control the time.
