Mobile OLED DDIC heralds smartphone displays without bezels

Analogue and mixed signal semiconductor company, MagnaChip Semiconductor, has launched a third generation, 40nm OLED display driver integrated circuit (DDIC) for the next wave of OLED smartphone displays. The rigid OLED DDIC supports various configurations such as FHD to FHD++, a wide aspect ratio up to 21:9 and bezel-less, edge type, and notch-type OLED displays. The 40nm mobile OLED DDIC already has won its first design-in at a leading smartphone player, reports MagnaChip.

The 40nm mobile OLED DDIC features lower power consumption and stronger protection against electrostatic discharge (ESD) and electromagnetic interference (EMI), compared to the second generation OLED DDIC. It also has enhanced compensation features that further improve colour and brightness uniformity.

With the addition of this 40nm mobile OLED DDIC, MagnaChip’s current mobile OLED display driver portfolio now includes six display drivers, including three 40nm rigid bezel-less drivers, two 55nm flexible bezel-less drivers, and one110nm rigid OLED driver.

According to industry observers, OLED technology has become the display technology of choice for smartphone makers because it is widely considered to enable thinner, curved and bezel-less mobile displays, offer wider colour gamut, higher contrast ratio, faster response time for video and lower power dissipation to reduce heat and preserve battery life as compared with last-generation display technologies.

YJ Kim, CEO of MagnaChip said: “The 40nm OLED DDIC . . . is the latest mobile OLED DDIC in our current mobile OLED portfolio, and we already are far along in the development of a next-generation 28nm flexible OLED DDIC that we anticipate will be sampled by the end of 2018 or early 2019.”

Since 2007, MagnaChip OLED DDICs have been adopted in a wide range of smartphones as well as other devices including virtal reality head mounted displays.

MagnaChip Semiconductor is a designer and manufacturer of analogue and mixed-signal semiconductor platform solutions for communications, IoT, consumer, industrial and automotive applications.
