When you mention the OLED screen, people will think of Samsung for the first time. After all, Samsung's Amoled screen promoted on mobile phones is deeply rooted in people's hearts.
But when it comes to OLED screens, Sony has a deeper root.
At CES, Sony released the BRAVIA A1E series TV. Hirai Kazuo announced that Sony has returned to the OLED TV market. He also bluntly said that "only Sony can do OLED TV."
The latest news from the Japanese media shows that the Sony Xperia mobile phone will soon be converted to the OLED matrix. Considering the product development cycle, it is expected to be seen as soon as 2018.
At present, Sony's mobile phone products are LCD screens. After all, they are one of the three major shareholders of JDI.
In fact, compared to Samsung, Sony participated in the foundation of OLED technology earlier. For example, in 2004, it first mass-produced small-sized, full-color organic light-emitting diode (OLED) panels, which were used on mobile devices.
In 2007, Sony also released the world's first OLED TV XEL-1, but ultimately failed to adhere to it.
However, these years, the world's top professional monitors, Sony is insisting on the production of 4K resolution TRIMASTER EL OLED panel, the quality of the sky.
High Frequency Transformer
Applications of High-Frequency Transformers
1. Switch-Mode Power Supplies (SMPS)
High-frequency transformers are integral components in switch-mode power supplies, which are used to convert AC power to DC power in a wide range of electronic devices.
By operating at high frequencies, these transformers enable the use of smaller and lighter magnetic cores, resulting in more compact and efficient power supplies.
2. Inverter Circuits
Inverter circuits, which convert DC power to AC power, often employ high-frequency transformers.
These transformers allow for efficient power conversion at high frequencies, enabling the design of compact and lightweight inverters for applications such as solar power systems, uninterruptible power supplies (UPS), and electric vehicle charging stations.
3. Telecommunications
In telecommunications, high-frequency transformers are used for signal coupling and isolation in various circuit stages.
They ensure efficient signal transmission at high frequencies, maintaining the integrity of the communication link and reducing interference.
4. RF Amplifiers and Transmitters
In radio frequency (RF) electronics, high-frequency transformers are used in amplifiers and transmitters to match impedances and isolate circuits.
They help in maximizing power transfer efficiency and minimizing signal loss, ensuring optimal performance of RF systems.
5. Pulse Transformers
Pulse transformers are a type of high-frequency transformer specifically designed to handle fast-rising and high-voltage pulses.
They find applications in digital circuits, ignition systems, and other areas where precise control of electrical pulses is required.
6. Wireless Charging Systems
Wireless charging systems, such as those used for smartphones and other portable devices, often incorporate high-frequency transformers.
These transformers enable efficient power transfer between the charging pad and the device being charged, eliminating the need for physical connectors.
7. LED Lighting
In LED lighting applications, high-frequency transformers are used to convert the main AC power supply to the DC voltage levels required by LED drivers.
By operating at high frequencies, these transformers contribute to the overall efficiency of LED lighting systems, helping to reduce energy consumption and heat generation.
8. Industrial Automation and Control Systems
In industrial automation and control systems, high-frequency transformers are used in various circuits to handle high-frequency signals and provide electrical isolation.
They ensure reliable and efficient operation of the automation equipment, contributing to increased productivity and reduced downtime.
In summary, high-frequency transformers are essential components in numerous applications where the ability to handle high-frequency signals and the associated benefits of size reduction, weight savings, and improved efficiency are important. Their versatility and performance make them ideal for use in switch-mode power supplies, inverter circuits, telecommunications, RF electronics, pulse transformers, wireless charging systems, LED lighting, and industrial automation and control systems.
