In the field of “green and low-carbon”, we have reduced the power consumption of U9 devices by 8% compared with conventional OLED devices on the market through innovations in materials and structures. At the same time, we have also successfully developed Tianma’s unique SLOD (Stacked Layer OLED Device) device, which is formed by connecting two light-emitting units with a charge generation layer (CGL) and electrically connecting them in series inside the device. Tianma has achieved a significant reduction in power consumption through a unique device design solution, which is 30% lower than conventional stacked devices.
In the field of “healthy eye protection”, we have ensured a significant reduction in screen power consumption through a variety of technical combination strategies, while reducing the proportion of high-energy blue light to 4.7%.
Looking to the future, we are committed to building SLOD technology into an innovative platform for OLED. By integrating new technologies such as blue phosphorescence, TADF (thermally activated delayed fluorescence), PSF (photosensitive fluorescence), etc., we will achieve high-performance OLED display effects such as low power consumption, long life, low blue light radiation, high brightness, and wide color gamut, truly realizing green, healthy, and high-definition display, and further highlighting the advantages of SLOD technology.
Extreme narrow frame technology
The narrow frame design can provide a larger viewing area for the screen, optimize the display appearance, and also bring users a more extreme visual immersion. Tianma has developed an innovative “Smart and Wonderful” extreme narrow frame technology. Through systematic mechanical simulation and technological innovation, it has accurately developed an integrated ultra-thin structure, and combined with high-precision sealing technology to improve the waterproof/grease-proof performance of the screen, achieving a module upper frame of 1.0mm, left/right/bottom frames of 1.2mm, and an ultimate visual experience of up to 95% screen-to-body ratio.
Multi-Form Folding Technology
In order to continuously explore the morphological boundaries of OLED displays and accelerate the commercialization of multi-form folding, Tianma has established a multi-form folding full-scene simulation platform with 6 dimensions and 30+ sub-scenes, including basic materials, morphological simulation, bending evaluation, impact resistance evaluation, surface evaluation, and process influence. Through the construction of the simulation platform and continuous technological innovation, we not only quickly mass-produced left-right inward folding/up-down inward folding products, but also successfully developed a “spiritual” curved and boundless G-form tri-folding product. In the future, Tianma will continue to innovate and make breakthroughs in multi-form folding to bring users a more creative user experience.
