The automotive industry constantly revolutionized ways to improve aesthetics and safety. One of the emerging technologies to transform headlights is OLED (organic light-emitting diodes). These lights offer many technological advancements and benefits that make them superior to the older headlight technologies.

Here, in this blog, we will explore OLED technology, its advantages, its comparison with other headlights, and ways to select the right kind of OLED light. So, buckle up to discover how OLED lights are shaping the future of automotive illumination.

What is OLED Technology?

OLED Technology

Organic light-emitting diode lights (OLED) are a new innovative technology that utilizes organic materials (carbon-based material) for the production of lights. The old traditional LEDs (light-emitting diodes) utilize both organic and inorganic materials, but their technology and operations are different.

Technical Aspects of OLED

The OLED technology produces very thin OLED lighting panels, light fixtures, and lightweight lights. Although they need a heat sink, they don’t start heating up like several other types of lights with proper thermal management. In addition, the light panel acts as a light fixture when you connect OLED panels to a driver (a device that controls light).

A phenomenon known as electroluminescence is responsible for the light emission in OLED. In these lights, the internal layer of organic matter sandwiches a cathode and an anode. The layer with organic material gets excited and starts emitting light when the electric current passes through it.

OLEDs also emit unique light patterns, including amber, which has a less blue effect, and thus, they are perfect for nighttime. Amber light is famous for its benefits in healthcare like improving sleep and reducing stress and anxiety. OLED is the safest light because the light emitted from it does not harm our eyes and skin.

OLED Technology in Automotive Headlights

OLED lighting technology is a way safer option in automotive lighting than traditional LED lighting technology due to its brightness, visibility, and reliability. LED lights are point light sources and generate heat which is then absorbed by the heat sink. OLED lighting solutions bring a revolution as they are flat and thinner light sources, reduce power consumption, and do not require reflectors.

There are several applications of OLED light in automotive lighting:

  • OLED lights reign supreme in producing straight, large-area light sources. There are applications in the exterior panel of a car, such as a rear display, to hint about the driver’s next step.
  • These are also used in signal lights, indicators, or flowing lights as well.
  • OLEDs increase the overall look of the interior of the car. They create a sense of luxury when used for dashboards, door panels, and footwells.
  • They have the feature to emit better, e.g., tail lamp lights.

Advantages of OLED Lighting in Automotive

In the automotive industry and lighting market, OLED (Organic Light-Emitting Diode) technology is trending as a game-changer and offers various advantages over traditional halogen and LED technology. The following are the key benefits of these lights in automobiles:

1. Enhanced Visual Clarity

OLED headlights can copy natural daylight thus improving visibility for drivers. They produce a broader color spectrum and that’s why emit light just like natural daylight resulting in reducing the eye strain for drivers. This lighting is well known for its uniform lighting distribution and providing clearer illumination.

2. Design Flexibility

This technology consists of incredibly thin and flexible light sources. The overall lighting of the car is customizable using this lighting including, headlights, tail lights, backlights, and every interior lighting. It can control the individual segment within an OLED panel for dynamic lighting effects. The thin appearance of OLEDs allows for their fixture on several surfaces within the car and the reduction of bulky lighting fixtures.

3. Energy Efficiency

Comparing OLED to Other Headlight Technologies

headlight technology comparison

Automotive headlights have undergone remarkable changes, developing from early gas lamps to innovative lighting today. This study compares four prominent lighting technologies: high-intensity discharge (HID), light-emitting diode (LED), halogen, and the trending organic light-emitting diode (OLED).

Feature HID (Xenon) LED Halogen OLED
Brightness Very bright, more than halogens Bright, often brighter than HID Less bright compared to HID & LED Moderate, less than LEDs
Energy Efficiency More efficient than halogens Most energy efficient Least efficient More efficient than halogens
Lifespan Long (up to 2,000 hours) Longest (up to 50,000 hours) Short (about 1,000 hours) Moderate (up to 15,000 hours)
Cost Expensive, less than LED Most expensive Least expensive Expensive, similar to LED
Color Temperature Usually around 4,200 Kelvin Can vary, typically 6,000 Kelvin Around 3,200 Kelvin Can be tuned
Light Distribution Wide and even distribution Precise and directional Scattered and less controlled Very precise and customizable
Startup Time Instant, but requires warm-up for full brightness Instant Instant Instant
Durability Sensitive to vibrations and impacts Very durable, shock resistant Sensitive to vibrations Very durable, shock resistant

OLED lighting and OLED displays have the same light emission process. A major difference is that an OLED display is a pixelated display for visuals that relies on different color pixel sets, each emitting a primary color of blue, green, and red. 

The arrangement of pixels is in a matrix form consisting of a driving transistor used to drive the pixel to display an image of full color. An OLED lighting panel is a single emissive surface producing even white light and is mostly aimed for illumination purposes. Here, take a brief look at the comparison of these lighting technologies with OLED lighting technology.


HID and OLED both hold a spot in the future of automotive headlights. However, they have many differences:

  • HIDs produce cool, white light directly, whereas OLEDs are a great choice. They are similar to daylight with a broader color spectrum.
  • Regarding energy efficiency, HIDs are moderately efficient, but OLEDs are highly energy efficient.
  • HID has a limited bulb-like shape. However, OLED is a flexible panel and holds aerodynamic headlight designs.
  • Currently, OLED bulbs are the most expensive. HID is more expensive than halogen bulbs but less expensive than OLEDs.
  • HID is a developed lighting used in high-end vehicles. In contrast, OLED is currently emerging light and is not widely available.

OLED VS. Halogen


OLEDs and Halogen lighting vary in different properties, some of which are:

  • OLEDs emit natural light, whereas halogen is a traditional yellowish light with low visibility.
  • Halogen has a lower efficiency of energy with 40-100 watts in a standard bulb than individual OLEDs which are highly energy-efficient.
  • OLED lighting is thin and flexible, but halogen limits the shape of the bulb.
  • Halogens are a cost-effective option for basic light; however, OLED lights are very expensive.
  • Halogens have a limited lifespan due to their fragile filaments, whereas OLED lighting is continually improving in terms of durability.


LED lighting and OLED are both innovative in-car lighting technologies. LED headlights are well suited for a cooler temperature. However, they serve differently according to their needs. Let’s take a look at their comparison:

  • LEDs are point light sources chosen as reading lights because of their brightness, but OLEDs are surface light-emitting sources.
  • LED lighting is a light with high-intensity illumination, whereas OLED is a natural and soft surface light source.
  • OLED light is thin, flexible, and customizable, whereas LED light offers limited size and placement.
