The Aerial car dashboard
integrated with the HUD provides
essential driving information such
as dashboard and navigation routes.
The information displayed can be
customized.
The display glass is
transparent and does not interfere
with the driver’s field of
view.
The image is projected 1.7m in front of the
driver. High brightness and low scatters ensure
image clearly visible even under sunlight.
Super-large image provides up
to 18° x
5° FOV at a
resolution up to 1280 x
640.
Installation is easy as the
very compact footprint requires as
little as 1L of space within the
vehicle.
Ultra-low power consumption
(compared to
AR-WHUD).
Integration of HUD and
dashboard lowers the cost of
introduction.
According to
customers' needs, in
addition to being used as a car
dashboard, it can also be used
simply as a
HUD.
The history of
automotive electronics began in the 1930s
when vacuum tube car radios began appearing
in cars. After World War II, the development
of semiconductors, the popularization of
microprocessors, advances in technology,
reduced costs and other factors all spurred
the rapid development of automotive
electronics.
automotive
electronics is a broad field whose
applications alone can be divided into
engine management, power control, chassis
electronics, passive safety, driving
assistance systems, passenger comfort,
entertainment systems, integrated electronic
cockpit system, and so on. With the
exception of automotive experts, the average
car user’s understanding of automotive
electronics is limited to what they see in
everyday life. An example of this is the
onboard dash camera that was introduced
quite
early.
Further
developments in automotive electronics
resulted in automotive electronics products
intended as driver aids or for
entertainment. Digital dashboards, car
stereos, head-up displays (HUD), blind spot
detection, panoramic vision, gesture
control, wireless charging, child presence
detection, driver fatigue detection and so
on are all examples of
these.
The
proliferation of automotive electronics
products also meant more distractions during
driving that indirectly introduce more risk
factors. They also complicate the design of
car interiors and clash with the
contemporary preference for minimalist
aesthetics. The latest car models now aim
for an integrated approach to automotive
electronics applications. An example of this
is the replacement of the traditional
central console and car stereo with a single
large
display.
The UniMAX HUD
Aerial Car Dashboard was created in response
to this new
trend.
The HUD Aerial
Car Dashboard not only combines the
attributes of windshield type HUD and
dashboards but also enhance the inherent
strengths of both
technologies.

Traditional Dashboard - The
Invisible Killer in Driver
Safety
The car
dashboard displays a great deal of essential
driver information such as speed, mileage,
RPM, engine temperature, fuel, indicator
lights and faults. automotive electronics
are therefore frequently
used.
Car dashboards
are placed forward of the steering wheel for
the convenience of drivers; they must also
be positioned lower down to avoid blocking
the driver’s view. The placement is
not ideal and poses a potential hazard to
driver
safety.
Firstly, the
driver’s eyes are looking into the
distance while driving. Placing the car
dashboard nearby meant that the eyes must
re-focus when they switch from looking into
the distance to looking at the dashboard.
The 20-degree angle between looking ahead
and look down at the dashboard meant the
driver is not looking at the
road.
As a result,
when the driver’s eyes shift to the
dashboard they must look down and focus on a
nearby object, then look up and focus on the
distance again. What this means is that they
took their eyes off the road for 2 ~ 3
seconds. If the car is moving at high speed
then such unsafe conditions may last for
tens of meters. Each glance at the dashboard
meant that the driver is placed in jeopardy
again.
Even though
the nature of dashboards meant that they
must be placed in a lower and closer
position, the UniMAX floating car dashboard
can not only be placed in the same location
as traditional dashboards; it also offers a
solution to the dangers posed by traditional
dash
boards.
2.1
Holographic
display
The HUD aerial car
dashboard uses optical technology to project the
image into the driver’s field of view a
distance of 1.7m away. The driver
can therefore see the information right away. Unlike
traditional dashboards, they do not need to spend time
refocusing their eyes.

Aerial Car Dashboard projects the image
1.7m in front of the driver. The massive
reduction in time needed by the eyes to
refocus on nearby objects improves
driver
safety.
2.2
Transparent material that
does not block the field of
view
Traditional
dashboards are placed about 20° below
the driver’s field of view to avoid
blocking the
route.
The UniMAX HUD Aerial
Car Dashboard is made from a transparent
materialso can be placed higher than
traditional car dashboards without fear of
interference. UniMax recommends
placing the HUD Aerial Card Dashboard about 10° lower
than the driver’s field of view. The driver can view the
dashboard info just by looking downward slightly or
through their peripheral vision, a
great improvement for driving safety. The installation
height can be customized to the customer’s
requirements.
The
transparent material offers more stylish and
high-tech possibilities for car design
aesthetics.

transparent material that does not
interfere with the driver’s field

slightly.
UniMax HUD
Aerial Card Dashboard not only retains the
advantages of the dashboard and solves
related safety issues. It also offers the
benefits of Windshield Type
HUD.

Windshield Type HUD - Many
Limitations and Poor Image
Quality
HUDs are
becoming more common in automotive
applications. Windshield Type HUDs can be
concealed into the car structure and the
holography imagery projected several meters
ahead of the driver integrates seamlessly
with the driver’s field of
view.
Windshield
Type HUD partially solves the safety issues
of dashboards as well. It can project
important dashboard information such as
speed and navigation information so that the
dashboard doesn’t have to be viewed as
frequently. It is a very convenient
automotive electronics product for
drivers.
Windshield
Type HUDs do have several technical issues
that are difficult to
surmount.
The Windshield
Type HUDs is concealed into the vehicle
structure. The light path structure and
large footprint means installations take up
a great deal of internal space. It
can’t be installed directly in every
car model and the parts need to be specially
designed. It is therefore not that easy to
install and heat dissipation is a big
challenge too. (Extended reading:

Flat Type AR HUD (MAVE) Solves
Installation Footprint
Problem)
As previously
mentioned, Windshield Type HD can project
and only project several pieces of key
information from the dashboard. This is
therefore both its advantage and
disadvantage.
The reason why
Windshield Type HUD can only project several
pieces of key information from the dashboard
is due to physical constraints. Windshield
Type HUD take up a lot of space but its
image quality (FOV and resolution) is
inadequate for replacing dashboards
entirely. The image is not big enough and
the resolution is not high
enough.
In addition to
the physical factors, Windshield Type HUD
projections are placed about 4° below
the driver’s field-of-view. Even if
the physical constraints are overcome and
all of the dashboard information can be
projected into the driver’s field of
view, this may increase risk by interfering
with the ability of the driver to read the
road. The physical
constraints and usage scenario are why
Windshield Type HUDs are limited to
projecting a small amount of
information.
The UniMax HUD
Aerial Car Dashboard retains the advantages
of the Windshield Type HUD while overcoming
its
weaknesses.
3.1
Small Footprint, Ease of
Installation, and Fast Heat
Dissipation
The UniMax HUD
Aerial Car Dashboard’s PGU, heat sink
and PCBA need to be buried into the car.
Their
total footprint is a small as 1L.Its
exceptional light path simplifies
cooling making it easier to install in
different car
models.
Caption: HUD
Aerial Car Dashboard is easy to bury in
cars due to its small footprint and low
cooling
requirements.
3.2
Super-large FOV and High
Resolution
The
UniMax Aerial Car Dashboard can achieve
a FOV of 18° x 5° or more with a
resolution of 1280 x 640 of
higher. It can not only
accept all information needed for
dashboards but also deliver
crystal-clear imagery. The dashboard
contents can also be adjusted to the
customer’s
needs.
As previously,
The HUD Aerial Car Dashboard can be
installed 10° below the driver’s
field of view . The driver only
has to look downwards slightly or even
use their peripheral vision to see the
dashboard
information. This not only
improves safety but also provides the driver
with a clear, wide-open view
again.

Aerial Car Dashboard is far superior to
WHD in terms of FOV or color. Pictured
above is the difference in viewing angle
and FOV between HUD Aerial Car Dashboard
and
WHUD.
The UniMax HUD
Aerial Car Dashboard is not only easy to
introduce but can also project all of the
essential dashboard information. It improves
driver safety and offers the advantages of
Windshield Type HUD without the
weaknesses.

Compatible with Advances in
Windshield Type HUD and
Dashboard
Technologies
The UniMax
Aerial Card Dashboard was developed in
response to the trend towards integrated
automotive electronics based on the reasons
given
above.
The UniMax Aerial
Card Dashboard’s transparency, holographic
projection, super-large FOV and high-resolution
as well as ease of installation means it can
replace traditional dashboards and cost less
than Windshield Type HUDs to introduce. It also
improves driver safety, enhances the car
interior, and leverages technology to take
drivers into the future.
