On June 23, 2025, GalaxyCore officially announced the successful delivery of its first AMOLED display driver IC (DDIC), model GC3A71, to a smartwatch client. With a high resolution of 400×400, flexible packaging compatibility, low power consumption, and wide color gamut performance, the GC3A71 precisely meets the core requirements of smartwatch display design and has been highly recognized by clients. This milestone marks GalaxyCore’s completion of key technological and algorithmic advancements in OLED displays and signifies its successful entry into the fast-growing OLED display market, further expanding the growth potential of its display driver business.
OLED displays, known for their slim profile, high contrast, and low power consumption, have become a major mid-to-long-term growth driver in the display industry. According to Sigmaintell, the OLED DDIC market is projected to maintain a compound annual growth rate (CAGR) of approximately 9.1% from 2024 to 2030, driven largely by applications such as smartphones and wearable devices. As GalaxyCore’s first major milestone in the OLED market, the GC3A71 offers a high-performance, high-compatibility and high-competitiveness display driver solution for smartwatches.
GC3A71 Specifications
GC3A71 supports GalaxyCore’s proprietary Chip-on-Glass (COG) packaging, which significantly reduces the module border, enhances screen-to-body ratio, and improves the visual integration of the device. This design also frees up more internal space for smartwatch manufacturers. The product integrates SRAM and features dynamic refresh rate technology, supporting refresh rates from 1Hz to 60Hz, enabling smooth visuals while minimizing power consumption to meet the endurance demands of wearable devices. In terms of display performance, GC3A71 supports 11-bit digital GMA output, delivering richer grayscale gradation and a broader color gamut for more refined images and vivid, lifelike colors.
GC3A71 also offers design flexibility to accommodate diverse client needs. It is compatible with both COG and Chip-on-Film (COF) packaging and supports both rigid and flexible AMOLED panels. The chip offers multiple communication interfaces, including 1-line, 2-line, and 4-line SPI, allowing clients to configure systems based on their specific requirements. Designed with industrial-grade reliability, the GC3A71 operates stably across a wide temperature range of -40°C to 85°C. Manufactured using a mature and stable 55nm process, it delivers an ideal balance of performance and cost, supporting clients in achieving commercial-scale deployment.
Howard Wang, Vice President of GalaxyCore Display BU, stated:
“The successful delivery of the GC3A71 marks a significant milestone in the development of GalaxyCore’s display product business. It signifies our official technological expansion from TFT-LCD into the OLED space, completing our product portfolio in the high-end display market. This breakthrough will further drive GalaxyCore’s growth in the OLED market. Building on this successful delivery, we will continue to upgrade our OLED DDIC offerings for wearable devices and accelerate the development of OLED solutions for smartphones and other terminal applications. We aim to drive coordinated development of our LCD and AMOLED product lines and continuously enhance our overall competitiveness.”
