Transparent Conductive Oxide (TCO) thin films — represented by ITO (Indium Tin Oxide) — are core components of the modern optoelectronics industry, broadly applied across touch panels, LCD/OLED displays, solar cells, e-paper, smart glass, and other diverse fields. As end products continue evolving toward larger dimensions, higher yield, and lower cost, the Roll-to-Roll process has become the mainstream choice for mass production of ITO flexible conductive films.
The Dah Young Vacuum TCRC (Transparent Conductive R2R Coater) is a large-width R2R sputtering system optimized for ITO and other transparent conductive oxide mass production. The TCRC employs 900 / 1100 / 1300 / 1700 / 2000 mm multi-width platforms, advanced German plasma monitoring technology, multi-cathode flexible configuration, and high-precision tension control — delivering industry-leading transparent conductive film mass production solutions for touch panel manufacturers, flexible electronics manufacturers, and solar module manufacturers.
Complete Width Spectrum | Matching Large-Format Mass Production Economics
Touch panel and flexible display sizes continue to expand — from 6-inch smartphone screens to 27-inch touch displays, large-format e-whiteboards, and smart glass — driving sustained demand for large-format ITO conductive films. The TCRC offers five web width options (900 / 1100 / 1300 / 1700 / 2000 mm) covering everything from medium production to maximum-format mass production, completing large-format substrate coating in a single process. This substantially improves production economics and per-piece cost competitiveness.
The core technical challenge of large-width coating is full-width uniformity control — conventional large-width R2R processes commonly face edge effects, batch differences, and plasma instability. The TCRC introduces advanced German plasma real-time monitoring technology, capturing plasma state in real time across the 2000 mm full-web range. This stably controls ITO coating uniformity within ±5%, effectively addressing traditional pain points in large-width processes.
Deeply Optimized ITO Process | Low Resistance, High Transmittance, Production-Grade Consistency
Two core optoelectronic properties of ITO films — Sheet Resistance and Visible Light Transmittance — directly determine touch sensitivity and display quality of end products. The TCRC combines MF (Mid-Frequency) power with precise reactive gas control to deposit high-quality ITO films with low sheet resistance and high visible-light transmittance — fully meeting touch panel and display industry mass production standards.
The TCRC's multi-cathode flexible configuration (planar + rotary targets) lets customers select the optimal arrangement per production needs — rotary targets provide longevity and material utilization advantages suitable for continuous mass production; planar targets provide precise thickness control suitable for specialty applications. For the touch and display industries seeking balance across electrical, optical, production efficiency, and equipment depreciation factors, the TCRC delivers the industry's most complete solution.
HiPIMS Option | High Ionization Rate Enhances Film Quality and Bend Resistance
Conventional ITO films are prone to micro-cracking under bending conditions, affecting long-term reliability for emerging applications such as flexible displays and foldable devices. The TCRC offers an optional HiPIMS (High Power Impulse Magnetron Sputtering) high-power impulse power supply — through high-ionization-rate metal plasma, it significantly enhances ITO film density and adhesion, substantially improving film reliability under bending and stretching conditions.
This HiPIMS upgrade option lets the TCRC not only meet conventional rigid ITO applications, but also address the high-end requirements of next-generation applications including flexible displays, foldable devices, and wearable electronics — providing Dah Young customers with a complete ITO process upgrade path.
