LCD glass is the core substrate for high-end display panels, demanding extremely high levels of transparency, flatness, and optical consistency. During production, defects such as bubbles, stones, uneven light transmission, and foggy images are the critical bottlenecks restricting yield rates. Ordinary industrial magnesium oxide features relatively high impurity levels and unstable powder reactivity, which easily induces glass melting defects.
Addressing the pain points of the optoelectronic glass industry, Messi Biology has custom-developed a high-purity heavy magnesium oxide specifically for LCD glass. With its characteristics of high purity, low impurity content, and strong thermal stability, it effectively eliminates internal bubble defects in glass, significantly enhances light transmittance and display image quality, and serves as a dedicated core raw material for high-end LCD panel production.
This product is meticulously refined through a high-temperature dead-burning (re-calcination) purification process, with a stable primary purity of ≥99.5%. It strictly controls color-imparting and low-melting impurities such as iron, calcium, silicon, and alkali metals, fundamentally eliminating problems such as glass yellowing, devitrification (crystallization), and stone formation. Compared with light magnesium oxide, high-purity heavy magnesium oxide features a dense crystal structure, uniform powder, and stable chemical inertness. It adapts well to the high-temperature melting conditions of LCD glass, does not decompose or generate gas prematurely, thoroughly avoids application defects associated with ordinary powders, and is suitable for various high-definition LCD and touch display glass production lines.
During the glass melting stage, this product possesses exceptional melt-adjusting capability, making it the core key to reducing bubbles. Upon addition, it optimizes the fluidity of the glass melt, promotes the rapid floating and complete discharge of micro-bubbles within the melt, and eliminates closed bubbles and pinhole residues. Simultaneously, it can precisely regulate the glass hardening rate and stabilize the equilibrium of the melting system, avoiding streaks, haze, and other blemishes caused by forming speed fluctuations, thereby rendering the glass substrate uniform and transparent while significantly enhancing overall light transmission performance.
Its advantages in optimizing optical performance are prominent. The high-purity and low-impurity characteristics effectively improve the visible light transmittance of the glass and eliminate color interference, allowing LCD screens to reproduce colors more realistically and present clearer, brighter images. Meanwhile, magnesium ions can inhibit crystal precipitation during the glass cooling process, preventing substrate turbidity and loss of transparency while ensuring optical consistency. Furthermore, it strengthens the internal silicate structure of the glass, enhancing the product’s impact resistance, thermal shock resistance, and corrosion resistance, thereby effectively extending the service life of LCD glass and suiting high-end applications such as automotive displays, commercial large screens, and precision touch screens.
