The Friction Disc 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.

In recent years, the color TV industry has experienced rapid growth, transforming modern televisions from basic viewing devices into advanced entertainment systems. With continuous innovation, a variety of new television technologies have emerged in the market, such as OLED TVs, QLED TVs, and laser TVs. These advancements have made TV experiences more immersive, offering users richer visual and auditory enjoyment. Today, we’ll explore the unique features of these cutting-edge television technologies.
OLED TV
First up is the OLED TV, which stands out among the latest television innovations. OLED TVs use organic light-emitting diode panels, allowing for extremely thin designs. According to current market data, the thinnest OLED TV available today is just about the thickness of a coin.
As a next-generation display technology, OLED TVs offer several notable advantages: ultra-thin design, vibrant and accurate colors, and excellent contrast ratios. From a health perspective, traditional LED-backlit TVs emit blue light, which may be harmful to the eyes over long periods of use. In contrast, OLED TVs are self-luminous and do not emit blue light, making them a healthier option for extended viewing sessions.
QLED TV
Next, let's take a closer look at QLED TVs. The term "QLED" stands for "Quantum Dot Light Emitting Diode." This technology uses quantum dots to enhance brightness and color accuracy. Unlike traditional LED displays, QLED TVs maintain consistent image quality over time, thanks to their stable light source.
Key features of QLED TVs include high brightness, excellent color reproduction, and greater flexibility in panel design. Many manufacturers believe that QLED technology will play a significant role in the future of television due to its reliability and performance.
Laser TV
Lastly, we come to laser TVs, a relatively new entrant in the television market. The main advantage of laser TVs is their ability to produce vivid and lifelike images. Additionally, they can support much larger screen sizes—often reaching up to 100 inches or more. This makes them an ideal choice for home theaters and large living spaces.
Laser TVs are known for their vibrant colors, wide color gamut, and excellent brightness levels. They also offer a more immersive viewing experience compared to traditional LED and CRT TVs.
