Question 1

How bright are your automotive OLED panels?

Accepted Answer

Current Atala products on the road have a brightness of 2,000 cd/m2. Higher brightness products, up to 20,000 cd/m2, are in development.

Question 2

What colors are available for automotive OLED lighting?

Accepted Answer

Currently, rear lighting is available in ECE/SAE qualified deep red. Additional colors like amber, white, and cyan are in development.

Question 3

What testing is done for automotive OLED panels?

Accepted Answer

Atala panels pass validation tests (typically thousands of hours), including, but not limited to:
High temperature and humidity storage and operation (up to 85C/85%RH)
Low temperature operation (down to -40°C)
High temperature storage (up to 105°C)
Thermal shock (down to -40°C and up to 85°C)
Mechanical shock and vibration
Corrosive gas and ESD

Question 4

Can you customize the size and shape of the segments?

Accepted Answer

Absolutely. Panel size and shapes and segment patterning can be completely customized to fit your project needs. We work closely with our customers to help balance OLED panel design rules with their automotive lighting vision.

Question 5

Can OLEDs be used for headlights?

Accepted Answer

Typically, no. Headlights are usually highly directed beams of light, making this an inefficient application for a diffuse, surface light source like OLED.

Question 6

Can you integrate multiple colors within one panel?

Accepted Answer

OLED technology is capable of this. Commercialization will follow market demand for this type of configuration.

Question 7

What is the maximum operating temperature of your panels?

Accepted Answer

For automotive tail lamps we pass JEDEC JESD22-A108 and A105 testing at operating temperatures ranging from -40°C to 85°C. We also pass storage testing at 105°C.

Question 8

What is the lifetime of your automotive OLED panels?

Accepted Answer

Most Atala products are certified for lifetimes over 15 years, but we can work with customers to ensure that our products meet their manufacturing and lifetime requirements.

Question 9

What size OLED panels can you make?

Accepted Answer

While OLEDs can theoretically be made in any size, there are practical considerations in production that limit the possibilities of size. Very small panels are not practical due to unlit edges necessary for handling and FPC attachment, and large panels are limited by production capabilities and decreased yield. Speak with the OLEDWorks team for details on Atala design parameters.

Question 10

What is the vibration specification of OLEDs?

Accepted Answer

Atala products are tested to pass DIN 60068-2 vibration testing taillight specifications for broadband vibration and mechanical shock.

Question 11

How many segments are possible within a single panel?

Accepted Answer

Atala Digital and Atala Wave products available for immediate design-in can include up to 128 segments in one panel, but higher segmentation products are in development. We have shown demonstrators with up to 600 segments at trade shows and events.

Question 12

How long does development take for an automotive OLED solution?

Accepted Answer

Development timelines depend on the product specifications and the requested testing and development phases. Design confirmation and prototyping typically range from 6-20 weeks, while commercial products typically take 1-2 years, depending on the application and testing required. We work alongside each of our customers to provide a more accurate timeline as we progress.

Question 13

How well do your panels resist UV?

Accepted Answer

Our Atala panels pass DIN 75 220 testing protocol through an appropriately tinted lens:
1000 ±100 W/m²
240h dry climate T = 42 ±3 °C, H < 30 % rel.
240h humid climate T = 42 ±3 °C, H > 60 % rel.

Question 14

Can LED drivers be used for OLEDs, or are there any special technical specifications required?

Accepted Answer

Yes, any driver can be used if it meets the current and voltage requirements. When selecting a driver, please note that our OLED panels require drivers with a common cathode, or a high side driver.
