One of WICOP’s most transformative advantages lies in its ability to support full-array local dimming through its integration into Mini LED displays. This results in deeper blacks, brighter whites, and vastly improved image contrast. Automotive displays equipped with WICOP Mini LED can achieve peak brightness levels of up to 1,200 nits—substantially higher than many conventional in-vehicle display panels. This ensures excellent visibility in bright daylight, an essential feature for navigation and dashboard interfaces.
At the same time, the technology offers full compatibility with High Dynamic Range (HDR), delivering crisp and immersive visuals with wide color gamut and nuanced contrast. The ability to retain these visual characteristics while minimizing energy usage is a major win for EVs, where battery efficiency remains a top design priority.
In addition to superior optical performance, WICOP is highly resilient to the rigors of automotive environments. It demonstrates remarkable thermal stability, vibration resistance, and long-term operational reliability—critical for maintaining consistent performance over the lifetime of a vehicle. Whether under extreme temperatures or continuous use on rough terrains, WICOP maintains its integrity and visual clarity, outperforming many competing technologies in long-term durability tests.
Economic and Engineering Advantages Over OLED
WICOP’s cost advantages are equally noteworthy. Despite matching or exceeding the performance metrics of OLED in several key areas, WICOP Mini LED displays are up to 25% more cost-effective. This makes them especially attractive to automakers and Tier 1 suppliers who are under pressure to deliver high-performance user interfaces at scale without inflating production budgets.
Moreover, the ultra-slim design enabled by WICOP’s no-wire, no-package architecture significantly reduces display module thickness. This allows for sleeker, more integrated dashboard designs—freeing up valuable space within the cockpit for additional electronics or user features. As vehicle interiors shift toward tablet-style dashboards and integrated screen clusters, this space efficiency becomes a major asset in both form and function.
For engineering teams, WICOP’s simplified architecture also means fewer failure points, streamlined assembly, and improved supply chain logistics. With no need for bonding wires or encapsulation, manufacturing yields are higher and production is more scalable. These benefits further reinforce WICOP’s value proposition in a cost- and quality-sensitive automotive landscape.
Strong Global IP Protection Strengthens Competitive Edge
