TDK Transparent Conductive Film (FLECLEAR® / Ag Stacked Type)

1. One-sentence Definition

This functional film is fabricated by depositing silver alloy (Ag) or ITO transparent conductive layers onto PET substrate. It features high light transmittance, electrical conductivity and flexibility, serving as an alternative to conventional ITO glass with outstanding flexibility, low sheet resistance and high reliability.

2. Core Functions

• Transparent Electrode: Delivers uniform conductive surface without blocking visibility, replacing traditional ITO film and glass.

• Flexible Circuit Substrate: Bendable and rollable, applicable to flexible displays, touch panels and lighting systems.

• Light Regulation: Changes light transmittance when electrified, ideal for smart windows and dimmable glass.

• Transparent Heating: Generates heat under power supply for defogging, de-icing and thermal insulation, widely used in automotive, architectural and instrumentation fields.

• EMI Shielding & Antenna: The transparent conductive layer can be made into transparent antennas, EMI shielding films and RFID window films.

• Photovoltaic Electrode: Acts as transparent electrode for Organic Photovoltaic (OPV) cells to boost power generation efficiency.

II. Key Advantages (vs. Ordinary ITO Products)

• Material: TDK mainly adopts Ag stacked structure, and ITO coated type is also available.

• Light Transmittance: Visible light transmittance ≥ 85%, close to glass.

• Sheet Resistance: Ultra-low resistance (≤10 Ω/□), lower and more stable than regular ITO film.

• Flexibility: Withstands over 100,000 repeated bends without cracking or performance failure.

• Environmental Resistance: Excellent moisture, heat and weather resistance, suitable for automotive, outdoor and industrial environments.

• Heat Insulation: High infrared reflectivity for thermal insulation and energy saving in summer.

• Production Process: Manufactured by roll-to-roll technology, featuring lower cost and support for large-size production.

III. Application Scope & Scenarios
