Merck, a global materials company, is playing a key role in next-generation OLED and digital optical materials for IT and mobile displays through collaborations with Korean and global panel manufacturers.

Merck held a media booth tour at the '2025 Korea Display Industry Exhibition (K-Display 2025)' held at COEX on the 7th and unveiled a number of advanced material technologies related to OLED, digital optics, photoresist, liquid crystals, and sustainability.


Yong-Guk Yoon, head of the Optronics division at Merck Performance Materials, who delivered the opening remarks that day, said, “Merck provides various materials and technology solutions to help customers innovate their products,” and “We will continue to invest and conduct research and development as a strong partner in the display industry.”

Merck possesses unrivaled technological prowess in the field of OLED materials, based on over 190 years of history and expertise.

The OLED materials introduced at the booth are composed of high-efficiency color primes, electron transport layers (EBL), etc., and high performance can be achieved through the combination of emitter and host materials.

In particular, it is contributing to the development of next-generation displays by improving key elements such as OLED lifespan, efficiency, and color stability.

Merck verifies the properties and performance of its materials through various testing environments, thereby providing customized solutions to customers.

Because OLED materials have different properties required depending on the size, shape, and application of the display, Merck is focusing on developing customized materials that reflect these characteristics.


In encapsulation technology, one of the key factors that determines the lifespan of OLEDs, Merck also presented various solutions utilizing organic and inorganic materials.

Organic packaging materials are applied in the form of thin films and are suitable for flexible and free-form displays.

The inorganic bag material forms a high-density protective film through PE-CVD and ALD processes, and is suitable for fields requiring high durability, such as automobiles and mobile devices.

In particular, ALD (Atomic Layer Deposition) technology enables precise deposition at the atomic level, enabling the implementation of free-form displays and high-quality protection.The lake can be realized simultaneously.

Merck also presented various solutions for high-resolution patterning and precision process implementation in the photoresist field.

We are enhancing the efficiency and precision of next-generation display manufacturing processes with products that support both positive and negative tones and enable high-resolution hole patterns.

In the field of liquid crystal materials, we provide solutions that achieve high brightness, low power, and high contrast ratio based on UB-FFS technology.

It is suitable for IT and automotive displays, and can be combined with AI-based control technology to implement smart displays.

Merck introduced optical film technology utilizing Pancharatnam-Berry phase (PB Phase) in the field of digital optics.

This technology can be applied to VR devices and augmented reality displays, and can achieve high resolution with a thin and flat structure.

Additionally, RM (Reactive Mesogen)-based optical films are produced using UV curing and offer various functions such as color patterning, anti-reflection, and broadband reflection.

In particular, the anti-reflection film optimized for OLED realizes deep black expression and minimizes color distortion through ND+A technology, and is evaluated as an essential element for implementing advanced displays.

Merck considers sustainability a core value and is leading the way in improving energy efficiency and implementing resource-saving displays through UB-FFS technology.

This reduces the power consumption of LCD panels and contributes to minimizing carbon emissions by utilizing eco-friendly materials.

A Merck official said, “The future of the display industry lies in materials that simultaneously satisfy high performance and sustainability. “It depends on technology,” he said, adding, “Merck will lead the next-generation display ecosystem through customer-tailored solutions and global collaboration.”
