On April 5th, the microwhales held a spring conference in Beijing to formally launch the A series of flagship TVs for the 2017 Miniature Whale.
Hardware: Focusing on ultra-thin hardware, the biggest feature of the Micro Whale A series is its thinness. The micro whale has long been known as the world's first three-limit ultra-slim smart TV, with the thinnest frame to the back cover of 4.9 mm, the thickest. At the bottom of the fuselage frame to the back cover 25mm, only 3mm is used for the dedicated rack wall.
The microwhales even said that this is the only ultra-thin international top product that can be produced at present.
In terms of configuration, the Micro Whale A-series TVs use the original Samsung 4K frameless LCD panel, equipped with the third-generation "Sharp 3.0" technology and support HDR functions. At the same time, Microwhale Technology and Corning reached a cooperation, using Corning's glass light guide plate technology. With Cortex-A72 processor and Mail T820 flagship graphics chip, built-in Hi-Fi audio, A series of 55-inch storage is 2GB+32GB, 65-inch storage is 3GB+32GB.
Software: Focused on artificial intelligence In addition to the thinness of the hardware, the Whale Watch TV A series is the most compelling or built-in current industry's most popular artificial intelligence technology, including face recognition, voiceprint recognition, emotion recognition, voice Answering, image recognition, etc.
Specifically, the new micro-whale TV will support voice query weather, calendar reminders, content recommendations, stock inquiries, etc. Microwhale also said that its current language recognition accuracy has reached 98%, and identification time is only 0.98 seconds. In the future, other artificial intelligence functions will gradually come online. It is worth mentioning that the micro whale's previous smart TV will also receive the latest AI function support through software updates.
In addition, the new generation of smart TV system WUI2.0 refresh rate also increased by 50% relative to the previous generation. The function is also built-in "face recognition child lock" function, after the brush can be unlocked, so that children better use the TV at home to learn and play: through the face recognition is not a child, then automatically limit the time for children to watch TV So as to avoid children becoming addicted to television. If the user identified by the camera is not a child, the child mode will not be enabled, and adults can watch as they like.
In terms of price, the microwhales stated that because of the relatively high technology, the A-series is mainly targeted at the high end. 55 inch rack version price 8999, base board 9199; 65 inch rack version price 16999, base board 17199.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
How does TFT work?
TFT is the abbreviation of "Thin Film Transistor", generally refers to thin film liquid crystal displays, but actually refers to thin film transistors (matrix)-can "actively" control each independent pixel on the screen, which is The origin of the so-called active matrix TFT (active matrix TFT). So how exactly is the image produced? The basic principle is very simple: the Display Screen is composed of many pixels that can emit light of any color, and the purpose can be achieved by controlling each pixel to display the corresponding color. In TFT LCD, backlight technology is generally used. In order to accurately control the color and brightness of each pixel, it is necessary to install a shutter-like switch after each pixel. When the "blinds" are opened, light can pass through, and " When the shutters are closed, light cannot pass through. Of course, technically, it is not as simple as the one just mentioned. LCD (Liquid Crystal Display) utilizes the characteristics of liquid crystals (liquid when heated, and crystallized into solid when cooled). Generally, liquid crystals have three forms:
Smectic liquid crystal similar to clay
Nematic liquid crystal resembling a fine matchstick
Cholestic liquid crystal
The liquid crystal display uses filaments, and when the external environment changes, its molecular structure will also change, and thus have different physical properties-it can achieve the purpose of letting light through or blocking light-which is just like the blinds just now.
Everyone knows the three primary colors, so each pixel on the display screen needs three similar basic components described above to control the three colors of red, green, and blue respectively.
The most commonly used one is twisted nematic TFT LCD (Twisted Nematic TFT LCD). Existing technologies vary greatly, and we will cover them in detail in the second part of this article.
There are grooves on the upper and lower layers. The grooves on the upper layer are arranged longitudinally and the grooves on the lower layer are arranged horizontally. When no voltage is applied to the liquid crystal in its natural state, the light emitted from the light emitting layer of the twisted nematic TFT Display working principle diagram of Figure 2a will be twisted by 90 degrees after passing through the interlayer, so that it can pass through the lower layer smoothly.
When a voltage is applied between the two layers, an electric field is generated. At this time, the liquid crystals are aligned vertically, so the light will not be twisted-the result is that the light cannot pass through the lower layer.
(2) TFT pixel structure: The color filter is divided into red, green, and blue according to the color, which are arranged on the glass substrate to form a group (dot pitch) corresponding to a pixel. Each monochromatic filter is called It is a sub-pixel. In other words, if a TFT display supports a maximum resolution of 1280×1024, then at least 1280×3×1024 sub-pixels and transistors are required. For a 15-inch TFT display (1024×768), then a pixel is about 0.0188 inches (equivalent to 0.30mm), for an 18.1-inch TFT display (1280×1024), it is 0.011 inches (equivalent to 0.28mm) .
As we all know, pixels are decisive for the display. The smaller each pixel is, the larger the maximum resolution that the display can achieve. However, due to the limitation of the physical characteristics of the transistor, the size of each pixel of the TFT at this stage is basically 0.0117 inches (0.297mm), so for a 15-inch display, the maximum resolution is only 1280×1024.
