2023 OLED KOREA Conference “OLED, a premium electronic product lineup and micro display, a promising future industry”

/in /by

OLED KOREA, hosted by UBI Research, a market research company, will be held at the Central Park Hotel in Songdo, Incheon from April 12 to 14. OLED KOREA, which marks its 7th anniversary, is a business conference where top authorities in display from Korea, Japan, Asia, the United States, and Europe gather.

This conference will deal with the topics of OLED, which has become a premium electronic product, and micro-display for AR and VR, which are rapidly emerging as future industries.

In order for OLED to replace LCD, the emergence of phosphorescent blue materials is the most important. At this conference, Samsung Advanced Institute of Technology and UDC will introduce the direction of phosphorescent material development. Commercialization of phosphorescent blue materials will be an inflection point that can overturn the display industry.

There are two types of micro displays: micro OLED and micro LED. While micro OLED is leading the way for VR, micro LED is gradually taking its place in AR. In OLED KOREA, programs are composed of AR companies, micro display manufacturers, and related technology companies. It will be an important place to guess who will be the winner of the future micro display.

The pre-registration period for this conference is until April 7, 2023, and you can check program and speaker information and register for the event through the website (https://oledkoreaconference.com/).

Sony, announced the commercialization of 0.5-inch micro OLED with UXGA resolution

/in , /by

Sony announced the upcoming release of the ‘ECX339A’, a 0.5-inch OLED micro-display with UXGA resolution. According to Sony, it has achieved the world’s smallest pixel pitch of 6.3 μm, enabling a resolution 1.6 times higher than its predecessor, “ECX337A “(0.5-inch QVGA (1280 × 960)).

By employing newly-designed peripheral circuits that operate on half the voltage of previous model, it supports a high frame rate of up to 240 fps, with dual line progressive driving technique and low power operation.

According to Sony, the high resolution of the existing micro display had problems such as deterioration in picture quality and deterioration in viewing angle due to pixel pitch reduction; however, they have been improved by Sony’s transistor layout, process optimization, and compensation circuit. In addition, the color filter is deposited directly on the silicon substrate, reducing its distance from the light emitting layer, and the filter’s color array has been modified to secure the viewing angle properties while achieving high resolution.

The mass production schedule for the ECX339A is November 2018, and the sample price is set at JPY 50,000 (Tax not included). Sony expects this product to be applied to high-end cameras and head-mounted displays for virtual reality, which require the highest picture quality.
