According to foreign media reports, at the opening of IFA at the end of this month, LG will release its first and the world's largest MicroLED TV, reaching 175 inches.
MicroLED has the advantages of self-illumination, no burn-in, and can drive ultra-high resolution, which is considered to be the development direction of future display. At CES earlier this year, Samsung released the 146-inch "The Wall" MicroLED flagship TV.
It is understood that in addition to a breakthrough in size, LG's TV will also be thinner than Samsung's 80mm. Regarding the rumors, LG spokesperson did not confirm, but said that LG is indeed developing and researching MicroLED technology.
At present, LG's TVs mainly use LCD and OLED panels, but because the OLED panel burn-in problem is always uncontrollable, Samsung refuses to use them in large-size TVs and longer power-on devices.
In July of this year, Samsung secretly demonstrated a 73-inch MicroLED TV at an internal meeting, which may be unveiled at this IFA. In addition, Samsung confirmed that it will release a higher-end MicroLED TV next year, with the thickness reduced to 30mm.
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.
