A recent study by Omdia predicts that global shipments of polarizer-free OLED display panels will reach 244 million units by 2032, with a compound annual growth rate (CAGR) of 22.7% from 2026 to 2032. OLED displays typically use a circular polarizer layer (CPL) to ensure light emitted from each pixel travels in a straight line. However, this process reduces optical efficiency, diminishing the brightness of OLED light passing through the polarizer by approximately 50% compared to its original level. Additionally, this single-layer film structure is relatively thick, imposing certain limitations on design and performance. To address these challenges, OLED manufacturers have developed polarizer-free OLED technology in recent years. However, due to higher investment costs and increased reflectivity, the technology is currently primarily used in high-end products. Recently, panel suppliers have begun extending this technology to a wider range of applications, thereby accelerating innovation in the OLED display market.

Jerry Kang, Head of Display Research at Omdia, stated: "For device manufacturers and consumers, the value of display innovation lies not only in the technology itself but also in its performance in real-world usage scenarios. COE technology offers several key advantages for device manufacturers, including higher light extraction efficiency, a thinner structure, and greater design flexibility. For consumers, the technology enables superior color performance and privacy features, which are expected to enhance user preference for OLED displays and further differentiate them from other display technologies."

One of the most representative examples of this technology is Color Filter-on-Encapsulation (COE). This technique involves precisely patterning color filters and a black matrix on top of the OLED encapsulation layer. Compared to CPL, the COE structure is thinner, leading to higher adoption rates in foldable smartphone panels. Since COE also offers higher light extraction efficiency than CPL, its application is expanding, particularly in specialized smartphones requiring high brightness or extended usage. COE also holds advantages for implementing under-panel cameras (UPC), as it can be designed according to the pixel structure without compromising the camera's light intake capability. Samsung Electronics' recently launched Galaxy S26 Ultra utilizes COE-based Privacy View display technology. This technology differs significantly from traditional privacy displays, as it can be activated across the entire screen or within specific screen areas. Furthermore, as display market competition increasingly focuses on enhancing color performance, COE is emerging as a potential alternative to CPL.

Polarizer-elimination technology is not limited to high-end innovations like COE. Other solutions, such as the Simplified Polarizer Layer (SPL), achieve polarization by restricting the light transmittance on the display surface. While this may result in reduced contrast, narrower viewing angles, and diminished outdoor visibility, SPL offers lower costs compared to traditional polarizer technology, making it a strong candidate for adoption in low-cost OLED panels.
