2.4-inch UV Tempered Glass Solution

2.4-inch UV tempered glass, a high-precision, highly weather-resistant display protection material, is widely used in small display screens such as smart wearable devices, industrial instruments, and medical equipment. Its core advantage lies in its surface strengthening through ultraviolet (UV) curing technology, while maintaining excellent light transmittance, impact resistance, and scratch resistance, providing a reliable protection solution for small display devices.

Material Properties and Process Optimization

2.4-inch UV tempered glass utilizes a low-iron ultra-clear glass substrate, ensuring high light transmittance (typically ≥92%), meeting the requirements of high-definition displays. After bonding to the glass surface with a UV adhesive coating, it is rapidly cured by UV light (curing time ≤30 seconds), forming a hard protective layer. This process avoids the high energy consumption of traditional thermal tempering while achieving localized strengthening, making it suitable for devices with special-shaped screens or touchscreen functionality.

Key Solutions

1. Drop and Scratch Resistance: The UV tempered layer has a Mohs hardness of 6H or higher, effectively resisting scratches from hard objects such as keys and coins, and improving its resistance to shattering in the event of a drop.

2. Lamination Precision: For small 2.4-inch screens, vacuum lamination technology is used to ensure a gap of ≤0.1mm between the tempered glass and the display, preventing edge whitening and air bubbles.

3. Customization: Surface treatments such as anti-glare (AG) and anti-fingerprint (AF) are available to meet the needs of various environments, such as outdoor devices with strong sunlight visibility.

Application Scenarios and Value

In applications such as smartwatches and small medical displays, 2.4-inch UV tempered glass not only protects core components from external damage but also enhances the overall aesthetics and lifespan of the device. Its lightweight nature (single layer thickness is typically 0.3-1.1mm) further optimizes device portability.

In summary, 2.4-inch UV tempered glass provides an efficient and reliable protection solution for small display devices through material innovation and process upgrades, and is an important technical choice in the current precision electronics field.
