The latest report from the analytics company Omdia indicates an upcoming revolution in the construction of OLED screens. The abandonment of the traditional polariser layer (CPL) in favour of newer solutions is expected to bring significant benefits in brightness and energy efficiency of devices. According to forecasts, shipments of such panels will increase to 244 million units over the next six years.
COE Technology: The Key to Energy Efficiency and Slim Design
Standard OLED panels utilise circular polarizers, which are responsible for directing light but also serve as a barrier to brightness – they absorb nearly half of the light generated by the pixels. Transitioning to Color Filter-on-Encapsulation (COE) technology allows for the elimination of this physical layer. Instead of a thick film, colour filters are applied directly to the protective layer of the diodes, which dramatically reduces the thickness of the entire panel.
The first example of such a solution is the latest "budget" OLED SE panel produced by LG Display. These panels will be found in television models such as LG B6, Panasonic Z85C, and possibly Samsung S85H.
This solution is particularly important for devices with limited space, such as foldable smartphones or VR goggles. Higher luminous efficiency directly translates to lower energy consumption by the device, which allows for extended operating time on a single charge without the need to increase battery capacity. An example of the practical implementation of this innovation is the Samsung Galaxy S26 Ultra model, which, thanks to the new panel structure, offers advanced privacy features and better readability in bright sunlight.
The market is anticipating rapid growth
Although technologies eliminating polarizers in mobile devices initially only found their way into the most expensive flagship models due to implementation costs, there is now a visible trend towards expanding their availability. It is estimated that by 2032, the number of panels of this type delivered annually will reach 244 million units. In addition to top-tier solutions like COE, manufacturers are also developing simplified polarizing layers (SPL), which, at lower production costs, have a chance to reach cheaper models of smartphones and tablets.
The new screen architecture also makes it easier to hide cameras beneath the display surface. With fewer layers for light to penetrate, under-display cameras can capture higher quality images, which has been the main barrier to their widespread adoption until now. Everything indicates that over the next decade, traditional "thick" OLED panels will completely give way to a new generation of displays.
