At ICDT 2026, held in Chongqing, China starting March 31, Tianma presented a new direction for mobile OLED competition by emphasizing both high refresh rate and full-screen technologies in smartphone AMOLED displays.

At this exhibition, Tianma unveiled an Ultra-high Refresh Rate AMOLED and an FSD (Full Screen Display) AMOLED, along with an integrated panel combining both technologies. Notably, it achieved a 240Hz-class refresh rate and a 98.5% screen-to-body ratio simultaneously in a mobile OLED panel.

The Ultra-high Refresh Rate AMOLED focuses on delivering refresh rates exceeding 200Hz. Tianma applied a circuit structure that separates data writing and TFT driving, addressing the long-standing trade-off between speed and accuracy in conventional AMOLED panels. In addition, by significantly extending compensation time, the panel delivers clear image quality without motion blur even at high refresh rates, ensuring fast response, color uniformity, and long-term reliability.

The FSD (Full Screen Display) AMOLED, on the other hand, focuses on bezel reduction. By adopting an integrated panel-module structure, Tianma achieved a uniform ultra-narrow bezel on all four sides. The bezel width was reduced to 0.35 mm at the panel level and 0.6 mm at the module level, resulting in a screen-to-body ratio of up to 98.5%. This represents a further reduction beyond the physical bezel limitations of conventional smartphone OLED displays.

The most notable exhibit was the integrated panel combining both technologies. Tianma demonstrated a 6.32-inch AMOLED panel achieving both a 240Hz refresh rate and a 98.5% screen-to-body ratio, indicating that mobile OLED development is moving beyond a trade-off between performance and design toward simultaneous advancement of both.

Considering that a representative premium smartphone such as the Galaxy S26 Ultra offers a 120Hz refresh rate and approximately a 90.7% screen-to-body ratio, Tianma’s exhibited panel surpasses it in terms of specifications.

However, whether such performance can be maintained in mass production with competitive yield and cost remains uncertain. Ultra-high refresh rate operation and extreme bezel reduction impose significant challenges in power consumption, heat generation, process complexity, and profitability. Nevertheless, Tianma’s exhibition demonstrates that Chinese OLED makers have moved beyond a catch-up phase and, in certain areas, have reached a level comparable to leading players.
