Frequency conversion technology enhances the beauty of the image
Konka R1 TV's frequency conversion technology comes from three main directions: chip frequency conversion, screen frequency conversion and backlight frequency conversion. The processor frequency conversion refers to the built-in computing chip of the TV, and improves the input source for the network video signal. Because the current network video, although the resolution is not low but the code rate is low, this is to make the screen does not compromise the card, while the low bit rate video with a refresh rate of only 30hz video, making the picture in the high-speed movement appears a little card pause.
MEMC is a technology that many televisions currently use, and the principle of MEMC makes calculations for different motion picture motion estimations, and compensate motion pictures with different frequencies from motion vector information of the original image. This kind of compensation is a very advanced frame interpolation technique, which improves the fluency of the picture due to the increase in the number of frames, which is extremely evident in action movies.
Backlight Inverter - There are two types of backlights for LCD TVs, edge-lit backlights and direct-lit backlights. Side-entry backlights can make TVs very thin because they only need to have backlight strips on both sides of the TV and have high performance. The resin light guide plate or glass light guide plate will evenly lay the light on the back of the LCD screen. However, no matter how advanced the light guide plate is, the brightness uniformity of the side-entry type back-lit television is quite different.
Direct backlighting features a horizontal and vertical staggered LED lamp bead behind the LCD screen. In principle, each lamp bead can be individually turned off and on, resulting in brightness control of individual areas.
The Konka R1 TV backlight frequency conversion is based on the vertical backlight system, backlight frequency conversion technology is based on the principle of Local dimming and prism light guide plate two core technologies, Local dimming 16-way partition LED backlight source can be based on the chip recognition display screen brightness and darkness, intelligent adjustment The current duty cycle of the corresponding partition backlight is matched with the prismatic light guide plate developed by the company and the surface of the prism is designed with a special prism microstructure. Narrow the beam in the direction of the LED light to reduce the stray light interference in the adjacent area, making the picture contrast more intense.
In addition to backlight and frequency conversion, Konka R1 TV also introduced a new local contrast adjustment technology local contrast, the current market is the majority of television uses a single dynamic brightness curve adjustment, and Konka's local contrast technology by dividing the screen into 48x27 Units, a total of 1296 partitions, are controlled one by one according to the brightness and dark content of different partitions, thereby enhancing the display effect. And the frequency and intensity of this control will vary in real time depending on the picture.
It is not only the frequency conversion that improves the picture quality
In addition to frequency conversion technology, Konka R1 TV also introduces several very practical technologies, such as solid color hard screen, HDR, 12bit color wheel engine, timely 4K and so on.
Among them, the solid color hard screen is the most popular image quality improvement technology this year, which absorbs the backlight stray light through the light nano material, thereby purifying the backlight source color. On the basis of achieving a wide color gamut, the color purity is improved, and the advantages of more accurate colors and more realistic images are achieved. A brand of solid-color television that was previously evaluated by PC home uses this type of technology.
The Konka R1 TV's HDR technology incorporates Local Contrast technology into the original HDR. Before the image is output, the entire screen liquid crystal molecules are divided into 1296 areas, and the flip frequency and angle of the liquid crystal molecules are precisely adjusted according to the screen needs. Improve the contrast again and enhance the details of the picture. In addition, the timely introduction of HDR technology can also adjust the saturation and dynamic brightness compensation through software, thus achieving the SDR to HDR quality transformation, and making the ordinary movie, the picture quality is improved better.
The color wheel engine can be said to be the signature technology of Konka TV. The R1 TV adopts a 12-bit color wheel engine and performs 12bit color processing on the color details of the picture, so that the picture color can reach 68.6 billion color reproduction. Compared with 10bit color processing technology, 12bit is 64-times 10-bit color processing technology, color reproduction is more real and natural.
Timely 4K technology has been experienced in the previous M1, through the intelligent identification of signal source clarity, through the use of three-dimensional correlation compensation technology to enhance the clarity of the picture, so that the ordinary high-definition signal is converted into a more close to the ultra-clear quality.

Excellent HDR quality presentation
The characteristics of HDR are that the two are brighter and the darker ones are darker. At the same time, the overall sense of the picture can be very well balanced. Especially when the local highlighting screen is used, the traditional TV will show a whitish play, while HDR does not have such problems.
The high-brightness display is very uniform with other screens, and there is no overall whitening problem.
The same is true of this picture, the middle figure did not become obscured by the super bright picture two.
