42-inch OLED TV is about to come out

German equipment manufacturer Mbraun said recently that the company has received orders from TV manufacturers for OLED devices, which are mainly used for OLED TV panels, which means that 42-inch OLED TVs will soon be available.

At present, only Sony's 11-inch XEL-1 OLED TV and LG's 15-inch OLED TV are on the market. Although Samsung has publicly displayed several OLED TVs, it has not appeared on the market.

Mbraun said that although the OLED TV market has not developed as fast as expected, and user acceptance has been limited, Samsung and LG are working hard to promote OLED TV and prepare for mass production. From a technical point of view, the biggest problem with OLED TVs at present is the size. Too small a size is difficult for users to accept, while the size is too large, the cost is doubled, and the expensive products obviously cannot be accepted by users.

Daniel Karecovsky, Mbraun's flat-panel TV application marketing manager, recently said that the size of the OLED TV has been solved, and the next step is how to practice it. TV manufacturers have begun to exert their efforts in the OLED TV market, and Mbraun's externally supplied equipment also needs to increase production as soon as possible, otherwise it may not be able to keep up with the user's footsteps. It is believed that a large number of 42-inch OLED TVs will be available soon, and the price is within the reach of consumers.

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.
