Smartkem to Present Disruptive MicroLED Technology at IDW Japan 2025

Smartkem Head of Technology Transfer, Steven Tsai, will present Smartkem's breakthrough MicroLED-in-Package (MiP4) Backlight at IDW Japan on Thursday, December 4, 2025.

MANCHESTER, England, Dec. 1, 2025 /PRNewswire/ -- Smartkem, Inc. (NASDAQ: SMTK), a company developing a new class of organic semiconductor technology, will be presenting its first MicroLED-in-Package Backlight at the 32^nd International Display Workshops (IDW) Conference in Hiroshima, Japan, on Thursday, December 4, 2025 at 16:40 local time.

In a special topic of interest segment on Micro/Mini LEDs to be chaired by Rumiko Yamaguchi (Akita Univ.) and co-chaired by Tauto Nakanishi (JNC), Steven Tsai, Smartkem's Head of Technology Transfer, will be delivering a presentation based on the publication of a technical paper titled 'From Chip to Panel: High-Brightness, Low-Power Mini-LED Backlighting via MicroLED-in-Package (MiP4)'.

First debuted at Touch Taiwan in April 2025, and exhibited at Display Week in May 2025, Smartkem's first MicroLED-in-Package (MiP4) backlight using its proprietary technology has the potential to disrupt the global display market. Smartkem's 'chip-first' MicroLED architecture introduces a breakthrough approach to MicroLED display manufacturing with a low temperature process that simplifies production, improves yields and delivers an enhanced display performance. This new MicroLED-in-Package (MiP4) backlight simplifies assembly and yield management for display manufacturers and is designed for seamless integration of MicroLEDs to enhance today's Liquid Crystal Display (LCD) market, which represents approximately 65% of the global display industry¹.

Steven Tsai will be in attendance throughout the conference from December 3-5, and available for 1-on-1 meetings to showcase Smartkem's first 12.3-inch MicroLED-in-Package (MiP4) backlight.

Smartkem's MiP4
At the core of this advancement is Smartkem's proprietary Redistribution Layer (RDL) material, which interconnects four chip-first MicroLEDs in a series to form a single high-voltage chip—the MiP4. This MiP4 package is designed to replace existing MiniLED packages in LCD backlights and signage applications, offering:

• Higher brightness at lower power
• Lower expected production costs
• Compatibility with existing MiniLED die bonding equipment
• Shipping in MiP4-on-blue tape format for seamless industry adoption
