28nm OLED DDIC reduces form factor for smartphone displays

Using 28nm, the most advanced process for manufacturing organic light emitting diodes (OLED) display driver integrated circuits (DDICs), MagnaChip Semiconductor has introduced an OLED DDIC that achieves a form factor reduction that is 20 per cent smaller than that of the previous 40nm process. It is suitable for smartphones and other mobile devices, to minimise size and thickness.

MagnaChip also reduced the logic voltage from 1.1V, which was required for the existing 40nm products, to 1.0V, which reduces the current voltage consumption by more than 20 per cent and also extends battery life.

MagnaChip claims that this 28nm OLED DDIC provides best in class performance, power and feature with high performance/price value.

The 28nm OLED DDIC also is expected to improve the call quality of smartphones by reducing EMI levels by 20 per cent, compared to existing products based on the 40nm format. The 28nm OLED DDIC supports a range of display types such as rigid, flexible, foldable and virtual reality, augmented reality (VR, AR) applications, while maximising design options for full screen displays, such as bezel-less, hole type displays.

The 28nm OLED DDIC is part of a portfolio of nine advanced platform OLED DDICs offered by the company, including one 110nm rigid bezel-less, two 55nm flexible bezel-less and five 40nm rigid bezel-less OLED DDICs. MagnaChip adds that it plans to expand the feature set of OLED DDICs to include ultra-high definition (UHD) capabilities.

MagnaChip Semiconductor designs and manufactures analogue and mixed-signal semiconductors for communications, IoT, consumer, industrial and automotive applications.  The company’s Standard Products Group and Foundry Services Group provide a range of standard products and manufacturing services.

With over 40 years’ of operating history, MagnaChip, owns a portfolio of approximately 3,000 registered patents and pending applications, and offers customers engineering, design and manufacturing process expertise.
