Tandem OLED technology has been around for several years, but it has experienced a significant revival recently, particularly with Apple’s announcement of their first ever OLED-based iPad that incorporates a tandem structure. This development has reignited interest in the technology, prompting various industry observers to delve into its implications.

As consumer gadgets, including laptops and smartphones, gradually adopt Tandem OLED displays, it seems appropriate to explore how this technology functions, the distinct advantages it offers, and its potential to shape future devices. Moreover, it stands to compete with other emerging display technologies such as MicroLED and QDEL. Understanding these various technologies is crucial for consumers and industry stakeholders alike.

Exploring the Landscape of Tandem OLED in Consumer Electronics

In this article, we aim to provide an insightful overview of Tandem OLED while avoiding overly technical jargon (for those interested, a more detailed breakdown is available, including current technical challenges such as light-extraction inefficiencies). For readers who may be new to the subject, here’s a straightforward introduction to what makes Tandem OLED particularly intriguing for modern technology gadgets.

At its core, Tandem OLED screens, such as the one featured in the M4 iPad Pro, consist of two layers of red, green, and blue (RGB) organic light-emitting layers that are meticulously stacked on top of one another and operate in tandem. This innovative architecture allows Tandem OLED displays to achieve the same brightness levels as conventional single-stack OLED designs while reducing the operational current through each layer. Consequently, the primary advantages of Tandem OLED technology include a significantly lower risk of burn-in, reduced power consumption, and the capability for achieving higher brightness levels without compromising performance.

This article will utilize the term “Tandem OLED” to refer specifically to displays utilizing two layers of RGB OLED materials. This is the configuration that has recently captured public attention through devices like the iPad Pro and the XPS 13. However, it is worth noting that other OLED displays employ various forms of tandem structures as well. For instance, OLED TVs and monitors that use LG Display’s WOLED (white OLED) and Samsung Display’s QD-OLED (quantum dot OLED) also feature tandem stacks at their core.

Interestingly, QD-OLED screens make use of three stacks of blue OLED emitter layers, which reportedly addresses the inefficiencies typically associated with blue emitters. As Ross Young, CEO at Display Supply Chain Consultants (DSCC), elucidated in a recent communication, “WOLED utilizes two blue layers along with red and green in a stack, while QD-OLED employs three blue layers alongside green in a stack. The distinction lies in the fact that these panels are solely generating white (WOLED) and blue (QD-OLED) light, setting them apart from the RGB tandem stacks employed in the OLED iPad Pros and certain automotive displays.”

Despite the impressive advancements represented by modern OLED TVs, which already derive significant brightness from their existing multi-stack OLED architectures, there might be limited motivation for Tandem RGB OLED stacks to penetrate the high-end television market. Eric Virey, a principal displays analyst at Yole Intelligence, remarked on the complexity of the manufacturing processes involved:

Moreover, the production techniques utilized in TV manufacturing diverge from those in smaller OLED devices, rendering them incompatible with RGB Tandem OLED designs. To elaborate, small OLED displays—such as those found in smartphones, tablets, smartwatches, and laptops—employ Fine Metal Mask (FMM) patterning technology. In contrast, larger OLEDs, such as televisions, utilize an open mask technique. The latter process is not applicable for RGB Tandem OLED architectures.
