UTG Glass | Custom Ultra-Thin Glass for Foldable Displays

Custom UTG Glass for Foldable Displays

Our UTG glass (Ultra-Thin Glass) is designed for foldable displays, flexible electronics, wearable devices and other applications requiring a thin, lightweight and durable glass solution. We provide custom UTG glass according to your required thickness, dimensions, shape, bending performance, optical specifications and surface treatments.

Custom options include chemical strengthening, precision cutting, CNC processing and functional coatings. Our UTG glass solutions can be developed for prototypes as well as volume production according to customer drawings and application requirements.

UTG Glass Manufacturing Process

1. Glass Preparation

Ultra-thin glass is prepared according to the required thickness and material specifications.

2. Precision Cutting

Laser or precision cutting processes are used to produce the required dimensions and shapes while minimizing edge defects.

3. Chemical Strengthening

Suitable UTG glass can undergo ion-exchange chemical strengthening to improve surface strength and bending durability.

4. Edge Processing

Edges can be processed according to the product design and assembly requirements.

5. Coating & Printing

AR, AG, AF and other surface treatments can be provided according to the application.

6. Quality Inspection

Thickness, dimensions, appearance, optical performance and other specified parameters are inspected before shipment.

UTG Glass Exceptional Performance Characteristics

Don’t let the thin profile fool you – our utg glass delivers outstanding performance across multiple metrics. The chemical strengthening process creates surface compression levels exceeding 800 MPa, providing remarkable resistance to scratches and impacts. Despite its minimal thickness, our utg glass maintains excellent optical properties with light transmission exceeding 91% and haze values below 0.5%. These characteristics make it ideal for display applications where every photon matters.

The flexibility of utg glass opens new design possibilities previously unavailable to product engineers. Our thinnest variants can bend to radii under 20mm without fracturing, enabling innovative form factors and flexible display applications. This flexibility doesn’t come at the expense of thermal performance either – our glass maintains dimensional stability across temperature ranges from -40°C to 150°C, ensuring reliable performance in diverse environmental conditions.

UTG Glass Application-Specific Solutions

Wearable Technology: For smartwatches, fitness trackers, and AR/VR devices, our ultra-thin glass reduces weight while maintaining durability. We can create custom shapes with precise cutouts for sensors and buttons, all while meeting the stringent impact resistance requirements these devices demand.

Flexible Displays: Our ultra-thin glass serves as an ideal substrate for flexible OLED displays, providing superior barrier properties compared to polymer solutions. The glass’s inherent rigidity during processing combined with flexibility in the final application offers the best of both worlds for display manufacturers.

Medical Sensors: In medical applications where minimal thickness is critical for comfort and functionality, our glass provides chemical resistance against disinfectants while maintaining optical clarity for sensors and displays. We offer biocompatible coatings for direct-skin applications.

Consumer Electronics: From foldable smartphones to ultra-lightweight tablets, our glass enables the next generation of mobile devices. We work with device manufacturers to optimize thickness, weight, and performance for specific product categories.

UTG Glass Specifications

UTG Glass for Foldable Displays

UTG glass is primarily designed for display applications where conventional cover glass is too thick or rigid. Its ultra-thin structure allows manufacturers to reduce device thickness and weight while maintaining the surface characteristics of glass.

Typical display applications include:

• Foldable smartphone displays
• Flexible OLED displays
• Foldable tablets
• Wearable displays
• Curved electronic displays
• Flexible touch panels
• Automotive curved displays

For foldable display projects, the required thickness, bending radius, folding cycles, chemical strengthening and surface treatment should be evaluated together to achieve the required balance between flexibility, durability and optical performance.
