Custom-sized stretched LCDs can be produced without high tooling costs by using 2nd Cutting technology, which reshapes standard TFT panels into new dimensions. This approach reduces development time, lowers NRE expenses, and enables flexible prototyping. Manufacturers like CDTech apply precision cutting and edge passivation to ensure durability, making these displays suitable for demanding industrial, medical, and automotive applications worldwide.
(Edited on June 12, 2026)
Edge passivation protects newly cut glass edges by sealing micro-cracks created during the cutting process. These micro-cracks, if untreated, can expand under heat, humidity, or mechanical stress, leading to display failure.
CDTech applies a polymer-based edge sealant after precision scoring and breaking. This material penetrates microscopic fissures and forms a պաշտպան layer that prevents moisture ingress and crack propagation. Controlled curing ensures consistent adhesion and stability.
Key technical benefits include:
Reduced risk of delamination under high temperature and humidity conditions.
Improved mechanical strength along cut edges.
Enhanced long-term reliability for IEC-standard environments.
In internal validation, CDTech observed a measurable reduction in edge failure rates in harsh 85°C/85% RH testing conditions, supporting use in automotive and medical devices.
Rapid prototyping is enabled by reusing existing TFT platforms rather than developing new ones from scratch. Instead of building new masks, manufacturers modify pre-qualified panels through precision cutting and layout optimization.
CDTech leverages a library of mature TFT platforms across multiple size ranges. Engineers simulate electrical routing, brightness distribution, and structural integrity before cutting, significantly reducing development risk.
This approach delivers clear advantages:
| Parameter | Full-Custom TFT | 2nd-Cut TFT |
|---|---|---|
| Sample lead time | 12–16 weeks | 4–6 weeks |
| NRE cost | High ($50k+) | Lower ($5k–$20k) |
| MOQ | 10,000+ units | 1,000–3,000 units |
| Platform risk | New design | Proven base |
For example, a standard panel can be transformed into a bar-type display while maintaining brightness uniformity and signal performance, enabling faster product iteration.
Maintaining tight tolerances is critical for stretched TFT displays, especially those with elongated aspect ratios.
CDTech achieves high precision through CCD alignment systems and controlled cutting processes. Key tolerances include:
Positioning accuracy within ±10 μm.
Edge flatness within ±5 μm.
Edge chipping controlled below 30 μm.
After cutting, multi-stage grinding refines edge quality to a smooth finish, reducing stress concentration. Combined with alkali-free glass substrates, this ensures stability across wide temperature ranges.
These tolerances are essential to maintain alignment of driver ICs and flexible circuits, preventing signal errors and mechanical integration issues.
Standard glass cutting is optimized for fixed formats such as 4:3 or 16:9, based on mother glass production layouts. These constraints limit flexibility for unconventional shapes like ultra-wide or vertical displays.
When designers attempt to adapt standard panels, they often face:
Wasted display area due to masking.
Increased enclosure size.
High costs from full-custom redesigns.
2nd Cutting overcomes these limitations by reshaping completed TFT cells. CDTech applies this method to produce custom aspect ratios while preserving critical functional regions like driver IC zones and bonding interfaces.
This enables efficient production of unique formats such as 3:1 or 16:3 displays without redesigning the entire panel architecture.
Yes, 2nd Cutting is fully compatible with capacitive touch panels and optical bonding processes. CDTech integrates projected capacitive touch (PCAP) solutions using GG or GFF structures.
Before cutting, engineers simulate sensor layouts to ensure touch accuracy and avoid dead zones. After shaping, optical bonding is applied using OCA or LOCA materials to enhance display performance.
Key benefits include:
Improved visibility through reduced reflection.
Increased structural strength.
Better resistance to vibration and impact.
In industrial applications, bonded displays can achieve significant brightness improvements and meet environmental sealing requirements such as IP-rated protection.
2nd Cutting is particularly valuable for industries requiring customized display formats without high development costs.
Typical users include:
Industrial control system designers needing compact HMIs.
Medical device manufacturers requiring compliance-ready displays.
Automotive suppliers designing unique dashboard layouts.
Smart home product developers exploring new form factors.
CDTech supports these sectors with certified manufacturing processes and flexible customization options, ensuring reliable supply and consistent quality.
