Samsung Display Selected as Lead Company for National Project on 'Development of Ultra-High Resolution Oxide TFT'

[Asia Economy Reporter Jeong Hyunjin] Samsung Display announced on the 12th that it has been selected as the lead company for the national project to develop the next-generation core technology, 'ultra-high-resolution oxide thin-film transistor (TFT) development.'

Mobile displays used in smartphones and other devices require TFTs with fast electron mobility as the resolution increases, which raises the pixel density and the integration level of the TFT circuits controlling the pixels. Samsung Display has started research and development aiming to secure oxide TFT technology with electron mobility 10 times faster by 2024.

The technology led by Samsung Display in this development is an oxide TFT with significantly enhanced electron mobility that can be applied to ultra-high-resolution mobile OLEDs with about 1000 ppi (pixels per inch). It is considered a next-generation technology that greatly reduces power consumption, TFT process difficulty, and production costs. Currently commercialized oxide TFTs have an electron mobility of about 10 cm2/Vs (a unit indicating electron mobility), making them difficult to apply to mobile panels. Samsung Display explained that once the new technology is commercialized, it is expected to enable low-power ultra-high-resolution mobile panels.

This development project is part of the government-led research and development (R&D) project called the 'Display Innovation Process Platform Construction Project.' Since 2019, the Ministry of Trade, Industry and Energy has selected a total of 66 research projects aiming to secure next-generation core display technologies by 2025, supporting R&D activities of companies, universities, and others.

Chu Hyeyong, Executive Vice President and Head of the Process Research Team at Samsung Display, who oversees this national project, said, "This research is significant not only for developing next-generation TFT technology but also for strengthening the competitiveness of domestic materials, parts, and equipment technologies through collaboration among large corporations, small and medium enterprises, universities, and research institutes within the display industry ecosystem."
