Samsung develops new generation OLED screen for commercial use in 2025

 


【Lansheng Technology News】Samsung will commercialize a new generation of OLED panels in 2025. Currently, the red sub-pixels and green sub-pixels in Samsung OLED panels use phosphorescent materials, and the blue sub-pixels use fluorescent materials.


In the new generation of OLED panels, Samsung has replaced the original fluorescent materials with phosphorescent materials, thus greatly improving the luminous efficiency. The data shows that the phosphorescence luminescence efficiency can reach 100%, while the maximum fluorescence luminescence efficiency is only 25%.


It is reported that the main difference between phosphorescent OLED and fluorescent OLED materials is reflected in the internal quantum efficiency (IQE) because their light-emitting mechanisms are different. Fluorescent OLED light-emitting materials use the singlet state to emit light, while phosphorescent OLED light-emitting materials can use the triplet state to emit light, and their luminous efficiency can be four times that of fluorescent materials.


In addition, through the introduction of phosphorescent materials, the power consumption of phosphorescent OLEDs has been greatly reduced. It is reported that iPhones and Samsung's own flagships will use this OLED panel in the future, which is worth looking forward to.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
