Korean designer of mixed-signal semiconductor platform solutions, MagnaChip
Semiconductor Corporation recently developed a ground-breaking third-generation 40-nanometer (nm) OLED display driver integrated
circuit (DDIC)
. This advancement is set to usher in a new age
of smartphone OLED displays, as the new OLED displays will allow for features
that were previously impossible.

MagnaChip’s
rigid OLED DDIC allows for multiple configurations including FHD to FHD++. Other
features include a wider aspect ratio up to 21:9 as well as bezel-less, edge
type, and notch-type OLED displays (a bezel is the small strip of material on a
smartphone screen which is not part of the display and is used to hold the
touchscreen in place). But MagnaChip is not the only company using this
technology. California-based company Synaptics also released two new drivers for sampling
that include many of the same features like extra-long 20:9 infinity display
support, rounded corners, and bezel-less displays. 

This
groundbreaking OLED display technology also allows for lower power consumption,
a boon for the smartphone industry where battery life is a huge selling point.
The displays also feature stronger protection against electrostatic discharge
(ESD) and electromagnetic interference (EMI), making them more reliable and
with a better picture quality and color gradient.

 

OLED
technology is quickly becoming the display of choice for the smartphone
industry because it allows for larger displays, brighter colors, and no longer
uses bezels. The bezel-less displays also offer a variety of other benefits
including a wider color gamut, higher contrast ratio, faster response time for
video, and lower power dissipation to reduce heat and preserve battery life, compared
with older digital display technologies. OLED displays are more flexible and
far less likely to shatter under pressure. Furthermore, the displays don’t
require a backlight adding further to their flexibility and efficiency.

 

With
all these advancements, there’s no doubt that OLED displays are going to be a
key component in the next generation of smartphones. The massive array of
features that OLED brings to the table puts other display technologies such as
micro LEDs to shame. Not to say that Mini LEDs and other display technologies
don’t have their place in select applications, but OLEDs are the obvious choice
of display for the smartphone of the future.
