The Advantages of HDR (High Dynamic Range) Technology
The emergence of HDR technology can improve the range of the brightness of the TV screen display. As a simple example, when the TV displays brighter and darker images of different brightness, we are likely to change the overall brightness of the TV. Ignore some of the dim, or more bright, detail effects in the TV picture.
HDR high dynamic range display technology is definitely your gospel for friends who love watching Hollywood HD movies. This technology greatly enhances the brightness of the TV, while reducing the darkness, making the brightness range closer to the perception of the human eye, can better reflect the visual effects of people in the real environment, so that you can also have a cinematic level at home High-definition experience.
Film and video sources using HDR shooting technology can be realized long ago. For example, the embarrassment of Haoyuechuan used HDR-enabled devices for shooting, but the euphemisms we see through TVs are not HDR signals. . At present, professional content providers such as Amazon are already making HDR-related content and providing playback. Of course, it takes a long time to wait until HDR-related resources are widely available.
Is it worth starting now?
HDR is still a new technology, and new technologies are always particularly attractive. However, it is still far away from most of us. Although HDR has had official definitions and standards, TV manufacturers and content providers have also vowed to demonstrate their strength in this area. But just like 4K, it takes a long process to emerge from the emergence of new technologies. The combination of 4K and HDR will give us an unimaginable viewing experience. If sufficient funds are available, most users can wait for the popularity of HDR and its sources to start.
The electrolyte material inside the electrolytic capacitor, which has charge storage, is divided into positive and negative polarity, similar to the battery, and cannot be connected backwards.A metal substrate having an oxide film attached to a positive electrode and a negative electrode connected to an electrolyte (solid and non-solid) through a metal plate.
Nonpolar (dual polarity) electrolytic capacitor adopts double oxide film structure, similar to the two polar electrolytic capacitor after two connected to the cathode, the two electrodes of two metal plates respectively (both with oxide film), two groups of oxide film as the electrolyte in the middle.Polar electrolytic capacitors usually play the role of power filter, decoupling (like u), signal coupling, time constant setting and dc isolation in power circuit, medium frequency and low frequency circuit.Non-polar electrolytic capacitors are usually used in audio frequency divider circuit, television S correction circuit and starting circuit of single-phase motor.
