Low quiescent current and increased flexibility are combined in a fully integrated Power-Management IC (PMIC) for AMOLED screens to increase battery life. The PMIC has integrated DC-DC converters and an input-voltage range to provide all the power rails required for AMOLED screens in smartphones and other portable devices.
AMOLED, which stands for Active Matrix Organic Light Emitting Diodes, is a display technology. Smartphones employ this particular OLED display type. Super AMOLED is an AMOLED display with integrated touch functionality. Rather than having a touch-recognition layer on top of the screen, the layer is built into the screen itself.
A key component of the lower-voltage DC subsystem is frequently the power management IC (PMIC), as circuits frequently contain several power rails with strict requirements for each one of them as well as required links between them.
Triple DC/DC converters are integrated into the AMOLED Display Power Management IC to manage the power of the AMOLED display panel.
The global amoled power management ic market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A fully integrated Power-Management IC (PMIC) for AMOLED displays from STMicroelectronics combines a low quiescent current with more flexibility to prolong the battery life of portable devices.
The PMIC contains safety features like thermal protection, input under-voltage lockout, and soft-start with inrush current limiting, which all combine to maximize power savings. The high-voltage outputs also offer short-circuit protection and fast-discharge circuit.
The MAX17065 highly integrated power-management IC (PMIC) from Maxim Integrated Products contains regulated positive and negative charge pumps, a step-up DC/DC converter, an inverted DC/DC converter, and a low-dropout linear regulator (LDO).
AMOLED screens are driven by the MAX17065 and are utilised in items like cellphones, cameras, MP3 players, and others.
The MAX17065 is offered in a compact, 4mm x 4mm, 28-pin TQFN package and is fully specified for the extended temperature range of -40°C to +85°C. Pricing begins at $1.20 (for quantities of 1000 or more).
In order to win a flexible AMOLED automotive display solution design-win with a major new energy vehicle (“NEV”) maker, Himax Technologies, Inc., a leading supplier and fabless manufacturer of display drivers and other semiconductor products, and BOE Varitronix Limited, a global leader in automotive display products, announced their collaboration.
By utilising the Himax AMOLED driver IC and timing controller (TCON) solution, Himax and BOEVx collaborated to provide the next-generation flexible AMOLED vehicle display in a 12.8-inch Center Information Display product (CID).
AMOLED panel and driver in COF technology allow exceptional user visual delight from a cutting-edge OLED display from BOEVx with vibrant and colourful image performance as well as fashionable panel curvature.
Nordic Semiconductor recently introduced the multi-function nPM1300 Power Management IC, which includes an evaluation kit and special system management functions.
By integrating circuitry that generally requires five or more discrete components into a single chip, it lowers an end-product’s Bill-of-Materials (BoM). Along with the launch, the nPM1300 Evaluation Kit (EK) and the nPM PowerUP PC app were unveiled.
Developers don’t need to write any code to assess, configure, and implement the nPM1300 PMIC thanks to the EK and the app. Additionally, the PMIC adds special system management capabilities and precise fuel gauging for low power wireless applications.
This mix between great precision and low power consumption was first achieved by Nordic, and no other PMIC device in the marketplace can match it.
With the nPM1300, developers can quickly and easily add a compact, optimised power management solution to their low power devices, doing away with the requirement to design in system management features from start using five or six discrete components.
The first Power Management Integrated Circuit (PMIC) for IT devices with OLED screens has been released, according to an announcement from Magnachip Semiconductor Corporation. A PMIC is an essential part of any system that powers electronics.
Given how heavily reliant on power efficiency the battery life of portable IT devices like laptops and tablets is, it plays an increasingly significant role. This newly created PMIC interfaces with a system using an Inter-Integrated Circuit (I2C), which is based on integrated power IC technology from Magnachip.
As a result, it has the ability to handle processes including output voltage control, ON/OFF block, output voltage sequence management, protection circuit fault flag, and switching frequency transition, all of which give seamless communication and excellent performance.
This PMIC supports a variable refresh rate due to its quick transient response. As a result, a screen can automatically adapt how frequently it refreshes the display to meet the frame rate.
With refresh rates ranging from 60Hz to 240Hz, this function significantly lowers power consumption while enabling a fluid and comfortable viewing experience for games and high-definition media.
The power circuit might also be small and straightforward. This new IC includes one boost regulator for the power supply to source and gate drivers, one low dropout (LDO) regulator, two voltage reference operational amplifiers, three negative output LDO regulators, three high-current buck regulators for the power supply to a timing controller, and two operational amplifiers for the gamma buffer.
Electronic circuits that have this level of integration are smaller and operate more quickly. This PMIC, which was designed with powerful circuit protection, also offers thermal shutdown, under voltage lockout, over-voltage protection, short circuit protection, over-current detection, over-voltage shutdown, and clamping circuit.
It’s anticipated that OLED uses in IT devices would continue to grow. To meet shifting market demand and design needs, Magnachip will broaden the scope of its premium PMIC product line through technological validation for a variety of IT applications.
