BOSTON, April 17, 2024 /PRNewswire/ -- Automotive
heads-up displays (HUDs) are currently being met with great
enthusiasm and expectations. The increased usage of technology
while driving and with drivers having to deviate their gaze from
the road to look at the dashboard and center information displays
(CID) in vehicles have resulted in more road accidents over the
years. Drivers must deviate their gaze from the road to look at
on-board diagnostics (OBDs), check the GPS, select music, and so
on. HUDs present these images directly in the driver's line of
sight, thus reducing the need for the driver to look away from the
road.
This need helps increase road safety, making the automotive
industry consider HUDs a viable option to reduce driver
distraction.
The IDTechEx report, "Automotive Heads-up Displays 2024-2034:
Technologies, Players, Opportunities", provides a comprehensive
coverage of this space, from the most renowned 2-dimensional
technologies to the more futuristic 3-dimensional imaging
techniques that are set to revolutionize the automotive sector. The
report also covers key trends, market analysis, opportunities, and
granular 10-year forecasts for display volume (number of displays)
and value (US$), segmenting the industry by display type,
technology, and region.
The current dominant technology in this space is TFT-LCD,
providing good image quality, durability, and maturity. Most
importantly, it is also very scalable and comparably inexpensive
when compared with alternatives in the market. It is, however,
2-dimensional and lacks depth when signaling objects on the road
when used as a HUD. More than just displaying OBDs and car
information, it is envisioned HUDs will be able to signal potential
hazards on the road and further assist drivers while driving. These
are also known as augmented reality HUDs (AR-HUDs). Due to this
increased immersiveness, it is important to have a technology that
provides depth to the images and extended field of view (FOV) while
signaling key areas of interest on the road.
There are two technologies that can enable three-dimensional
imaging and are being experimented on HUDs: computer-generated
holography (CGH) and light field displays (LFDs).
Unlike two-dimensional displays or stereoscopic displays, these
3D technologies project virtual objects with true depth cues. LCDs,
OLEDs, and microLEDs are all examples of 2D technologies that
display images directly onto a flat surface. At times, they are
used to create an illusion of 3D images, where a 2D image is shown
to the left eye and a slightly different image is shown to the
right eye. This is known as a parallax effect. However, the
extended use of these 2D techniques to display 3D images induces an
effect known as vergence-accommodation conflict (VAC). VAC
is the disparity in distances between the virtual object and the
eye. Say, for instance, a virtual object is displayed 3m from the eye, but the eye naturally focuses on
a screen a few centimetres from the eye. This distance mismatch
causes user discomfort and nausea, meaning users cannot use these
stereoscopic displays for too long.
Several companies and research groups are therefore evaluating
the use of 3D display technologies such as holography and LFDs.
Holography, in particular, appears to be gaining more attraction
when applied to automotive HUDs, and there are some notable reasons
for this increased interest.
The first was addressed earlier and relates to its ability to
project virtual images with true depth cues and without a loss in
resolution. The driver experience is significantly more comfortable
when road obstacles are signaled by images that have depth. Much
like our everyday vision, we are able to seamlessly focus and
defocus on virtual objects, something that is not easily achievable
using 2D technologies. The varying depth cues offer a more
comfortable driving experience for the driver and can become more
helpful with signaling road obstacles that naturally have varying
depths.
Secondly, brightness is fundamentally important in HUDs. A
display technology that works well under varied ambient conditions
is essential, as key information must be visible in very
bright or dark conditions. CGH uses a coherent light source, and
this is most often a laser. Lasers are naturally very bright and
perform consistently under a wide range of ambient light
environments.
Companies specializing in holographic HUDs are focusing on two
key areas to compete with the dominant TFT-LCD technology: lowering
the cost of these devices and reducing their form factor.
Currently, larger form factors and increased cost mean these
devices are only suitable for larger, more expensive vehicles, also
known as premium vehicles. In order to become more competitive in
this market and benefit from the large market potential, cost and
form factors must decrease.
While holographic technology is considered suitable for
automotive HUDs, the comparatively poorer image quality when
compared to LCDs and OLEDs, mainly due to an effect known as
speckle, means that it requires further maturity to be
adopted in other applications in the long term.
IDTechEx's "Automotive Heads-up Displays 2024-2034:
Technologies, Players, Opportunities" report analyses the main
technologies and HUD types being developed and expected to grow
over the next decade. The challenge in developing automotive HUDs
is more than just ensuring the technology works accordingly; it
must comply with the very stringent regulations the sector demands.
This report covers key innovations in manufacturing as well as
coating requirements to enhance the performance of HUDs.
