□ “Driving the development of a sustainable display ecosystem through improved energy efficiency”

□ CTO Lee Chang-hee receives the ‘Jan Rajchman’ Award for EL-QD development contributions

Samsung Display announced on the 19th that its President and CEO, Lee Cheong, has been elected as a ‘Fellow’ of the Society for Information Display (SID).

As the world’s most prestigious display society, SID elects Fellows once a year through a rigorous process involving nominations from existing Fellows and review by the Fellow Selection Committee. The number of new Fellows is strictly limited to within 0.1% of the total membership for that year.

Regarding the election of President Lee Cheong as a Fellow, SID stated, “We recognize his contributions in leading various OLED technology innovations, starting with the development of the world’s first foldable display, and driving the advancement of the display ecosystem toward improved energy efficiency and sustainability.”

President Lee Cheong, who joined Samsung in 1992 and holds a Ph.D. in Chemical Engineering from POSTECH, was promoted to an executive in panel development in late 2012, contributing to the development of Samsung Electronics’ Galaxy S series and flexible OLEDs. In particular, he laid the foundation for Samsung Display to mass-produce foldable OLEDs for the first time in the world in 2019. Since then, he has served as ▲Head of the Module Center for the Small & Medium Display Business (’20), ▲Head of the Development Office for the Small & Medium Display Business (’21), and ▲Head of the Small & Medium Display Business (’23), enhancing the durability and technical completeness of foldable OLEDs.

President Lee also led the development of ‘LEAD™’, a polarizer-less technology that Samsung Display commercialized for the first time in the world in 2021. ‘LEAD™’ is an innovative technology that internalizes the function of blocking external light reflection into the pixels, removing the polarizer previously essential in OLED panels. This improves light efficiency to increase luminance while reducing power consumption. Its thinner profile also enhances design and engineering flexibility. Currently, ‘LEAD™’ is featured in various flagship products, supporting display innovation in mobile devices.

Furthermore, President Lee has led the world-first mass production of technologies such as ▲flexible displays with integrated touch sensors (’16), ▲full-screen OLEDs with camera holes (’18), and ▲OLEDs supporting Always On Display (AOD) with variable refresh rates of 1–120Hz (’22), establishing OLED as the dominant technology in the mobile display market.

Meanwhile, Lee Chang-hee, Executive Vice President and CTO of Samsung Display, received the Jan Rajchman Award, one of the individual honors bestowed by SID. The Jan Rajchman Award is given to individuals who have made outstanding academic achievements and breakthrough technical developments in the field of display technology. EVP Lee was recognized for his pioneering contributions to the development of innovative displays and components using OLED, Quantum Dot (QD), and Nano LED.

Samsung Display Develops High-Resolution OLEDoS Microdisplay for Next-Generation XR

/in , /by

Samsung Display researchers revealed it in a recent paper published in J. Soc. Info. Display, the official journal of the Society for Information Display (SID), that they have developed a next-generation OLED-on-Silicon (OLEDoS) microdisplay with 4032 PPI (pixels per inch). This technology is optimized for the next generation of XR devices, including virtual reality (VR), mixed reality (MR), and augmented reality (AR), with panels that dramatically reduce system power consumption and crosstalk while maintaining high resolution and image quality.

This 1.3-inch panel has an ultra-high resolution of 4032PPI, delivering images so precise that pixels are indistinguishable to the naked eye. This minimizes the screen door effect in VR and AR glasses, enabling an immersive content experience. The display of the Apple Vision Pro, released in 2024, features a high-resolution display with a size of 1.42 inches and 3,391 PPI.

In this paper, a pixel compensation circuit structure with 7T1C (7 transistors and 1 capacitor) structure was introduced for high-resolution implementation, which complemented the shortcomings of the previous generation, 6T2C structure, and realized a design that was strong against voltage deviation.

Existing 6T2C pixel structures have caused problems with threshold voltage (Vth) deviations and image distortion between small transistors when implemented in high resolution. Accordingly, Samsung Display’s newly devised 7T1C structure provides the following major advantages.

  • Improved Vth compensation accuracy: Suppresses luminance imbalance caused by threshold voltage deviation to ±2.75% (previously ±10.6%)
  • Reduced horizontal crosstalk: 1.3% (previously 2.0%)
  • Area efficiency optimized with a single capacitor
  • Improved SRU (short range uniformity): 97.3% (previously 90.4%)

In addition, improvements have been made in the way data is driven. The existing 6T2C circuit consumes a lot of power because it has to charge and discharge a data line every frame, but the 7T1C greatly reduced power consumption by a single charging method. For example, in the same full gray pattern, the power consumption of the source IC decreased from 120 mW to 0.1 mW.

In addition, while lowering the operating voltage through the 8V CMOS-based design, it secured more than 50% of the power efficiency compared to the previous one.

Samsung Display officially announced its dual-track strategy to develop RGB OLEDoS and white-based OLEDoS simultaneously last year, and this 4032PPI panel is considered the result of that technological achievement. Although the mass production date for this newly developed product has not been announced, this technology is expected to serve as an important step in accelerating the development of the next-generation XR device market.
