The latest report from the analytics company Omdia indicates an upcoming revolution in the construction of OLED screens. The abandonment of the traditional polarizer layer (CPL) in favor of newer solutions is expected to bring significant benefits in brightness and energy efficiency of devices. According to forecasts, the supply of such panels will increase to 244 million units over the next six years.
COE Technology as the Key to Energy Efficiency and Slimness
Standard OLED panels use circular polarizers that direct light but simultaneously act as a barrier to brightness – they absorb almost 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, color filters are applied directly to the protective layer of diodes, significantly reducing the overall thickness of the panel.
The first example of such a solution may be the latest "budget" OLED SE panel produced by LG Display. These panels can be found in television models such as the LG B6, Panasonic Z85C, and possibly the Samsung S85H.
This solution is particularly important for devices with limited space, such as foldable smartphones or VR goggles. Higher luminous efficacy directly translates to lower energy consumption by the device, which allows for longer 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, which, thanks to the new panel structure, offers advanced privacy features and better readability in bright sunlight.
The market is waiting for rapid growth
Although technologies eliminating polarizers in mobile devices initially only appeared in the most expensive flagship models due to implementation costs, there is now a trend towards expanding their availability. It is estimated that by 2032, the number of delivered panels of this type will reach 244 million units annually. In addition to top solutions such as COE, manufacturers are also developing simplified polarizing layers (SPL), which, at lower production costs, have the chance to appear in cheaper models of smartphones and tablets.
The new screen architecture also makes it easier to hide cameras beneath the display surface. Thanks to the reduced number of layers that light must pass through, under-screen cameras can capture higher quality images, which has previously been the main barrier to their popularity. Everything indicates that in the upcoming decade, traditional, "thick" OLED panels will completely give way to a new generation of displays.
