"Display glass" generally refers to the glass substrate or protective glass used on the surface of display terminals such as monitors, mobile phones, tablets, LED displays, and televisions. It is not ordinary glass, but an optically functional material specifically designed for display technology. Its core functions are protection, support, light transmission, touch control, and optical optimization.
Here's a clear definition:
Display glass = High-strength, high-transmittance, low-reflection, scratch-resistant optical-grade glass material (such as cover glass, substrate glass, optical glass, etc.) used on the surface of a display screen or as a substrate for a display panel to protect the screen and ensure image display quality.
Display glass includes two main categories:
1. Cover Glass – Protective glass for the outer surface
Commonly found in mobile phones, tablets, automotive displays, commercial displays, etc.
Characteristics: High hardness (e.g., Corning Gorilla Glass), scratch-resistant, impact-resistant, fingerprint-resistant, high light transmittance.
Examples:
Corning Gorilla Glass
3D Cover Glass
Automotive Center Console Screen Glass
Explosion-proof Tempered Glass for Large-size Commercial Displays
When used in LED displays, it's called tempered protective glass, outdoor explosion-proof glass, touch glass, etc.
2. Substrate Glass – Used in the internal structure of display panels
Used as an internal support layer or wiring layer for display technologies such as LCD, OLED, and Micro-LED.
Features: Ultra-thin, ultra-flat, low thermal expansion, good electrical insulation.
Types include:
TFT Substrate Glass (used in Gen 8.5 and Gen 10.5 factories)
Color Filter Glass
OLED Thin Substrate
Micro-LED Transfer Glass Substrate
Why is display glass important?
Because it determines:
Screen transmittance, brightness, and color
Surface scratch and drop resistance
Anti-fingerprint, anti-glare, and anti-reflective effects
Whether it supports touch control
The clarity and stability of the displayed image
