In the home appliance industry, “frequency conversion†is a very popular word. Products such as air conditioners, refrigerators, washing machines, and water heaters are gradually converted into frequency, mainly to save power and achieve higher functions. Recently, the new species of "Variable Frequency TV" has also emerged, and has become a hot topic of discussion on the Internet. Konka R1 series of new products are the most typical representatives of the inverter TV.
So what is the inverter TV?
The answer given by Konka is that the R1 series achieves improved image quality and energy saving through the main chip frequency conversion, backlight frequency conversion and screen frequency conversion. The chip frequency conversion mainly aims at the dynamic picture, reduces the blurring, halo, sawtooth, trailing and so on of the moving picture by multiplying the frequency of the picture frequency; The screen frequency conversion is the enhancement of the picture contrast; The backlight frequency conversion is through the real-time backlight partition. Controls the effect of enhancing image contrast, adjusting brightness and reducing power consumption.
In a word, Konka R1 greatly improves TV picture quality through the “frequency conversion†function.

The eliminator is a kind of Printer Accessories.
The cartridge is irradiated by laser beam to adsorb toner, and then the toner is hot pressed by fixing roller for printing. In this process, there will be part of toner residual, which can not be "granules returned to the warehouse"; Automatic cleaning function is not adsorbed new toner particles and directly print, will remain toner away, fully ensure the next printing effect. And the Plate-Grid plays an important role. When high voltage generator to a high voltage electrode, wire electrode with reseau formed between a strong electric field, and release the corona, wire electrode and the photosensitive drum ionizes the air between the air ions migrate to the drum surface, make the photoconductor (drum) surface is full of charge, so can spare toner "adsorption to warehouse", so as to save toner, The purpose of reducing environmental pollution.
