An OLED display power supply is a device used to regulate the power supplied to an OLED display. OLED stands for Organic Light Emitting Diode, and is a type of display technology that is becoming increasingly popular in electronic devices such as televisions, mobile phones, and computer monitors.
OLED displays are extremely thin, light, and energy-efficient, and are capable of producing brighter and more vibrant colors than traditional LCD displays. The OLED display power supply is responsible for providing the necessary electrical current to the display.
This current typically ranges between 5V and 12V, depending on the type of OLED display being used. The power supply also regulates the voltage and current to ensure that the display operates within its specified parameters.
The power supply must also be able to adjust the voltage and current levels in response to changes in the display’s power consumption, as well as in response to changes in environmental conditions such as temperature and humidity.
Additionally, the power supply must be able to protect the display from overvoltage and overcurrent conditions, which can damage or even destroy the display. In order to ensure the reliability and performance of OLED displays, it is important to use a power supply that is specifically designed for the display.
Many manufacturers offer custom power supplies designed for specific OLED displays, although there are also generic power supplies that can be used with any OLED display.
In addition to providing a reliable supply of power to the display, the power supply must also be able to interact with the display’s control circuit. This allows the power supply to adjust the voltage and current levels according to the display’s needs, and to protect the display from any overvoltage or overcurrent conditions.
The OLED display power supply is an essential component of any OLED display, and is responsible for ensuring the reliable and efficient operation of the display. By using a power supply that is designed specifically for the display, users can rest assured that their OLED display will be able to operate reliably and efficiently for many years.
The Global OLED Display Power Supply market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
According to an announcement from Magnachip Semiconductor Corporation, the business has introduced its first Power Management Integrated Circuit (PMIC) designed for IT devices that have OLED screens. An essential part of providing power to electronic devices is a PMIC. Since power efficiency has a major impact on the battery life of portable IT devices like laptops and tablets, it is becoming more and more significant.
This newly designed PMIC uses an Inter-Integrated Circuit (I2C) to communicate with a system. It is based on Magnachip’s integrated power IC technology. As a result, it can regulate features like switching frequency transition, output voltage control, ON/OFF block, output voltage sequence management, protection circuit fault flag, and ON/OFF block, all of which provide flawless connectivity and exceptional performance.
This PMIC’s quick transient response allows for a variable refresh rate. As a result, a screen can automatically modify the frequency of image refreshes to match the frame rate. This feature makes it possible to watch games and high-quality videos smoothly and comfortably while also significantly reducing power consumption.
Furthermore, the power circuit may be small and straightforward. One boost regulator, one low dropout (LDO) regulator, two voltage reference operational amplifiers, three negative output LDO regulators, three high-current buck regulators for power supply to a timing controller, and two operational amplifiers for the gamma buffer are all included in this new integrated circuit.
