Honor 400 Tempered Glass - Dux Ducis

High-precision protection for the Honor 400's brilliant display

The Honor 400 stands out with its smooth AMOLED screen and its design focused on extended visual comfort. To secure this display surface without adding bulk, the Dux Ducis tempered glass features a made-to-measure cut matching the exact dimensions of the smartphone, providing invisible mineral shielding that stays discreet day after day.

• Certified 9H Hardness: Heat-strengthened medium alumina glass offering extreme resistance to drops and abrasive friction.
• 96% Crystal-Clear Transparency: Distortion-free light transmission that respects colour accuracy and the brilliance of the AMOLED screen.
• Electrolytic Oleophobic Coating: Acts as a barrier against sebum marks, perspiration and residual dust.
• Zero-Latency Touch Sensitivity (0.33 mm): Smooth glide for fast typing and immediate compatibility with the under-display fingerprint sensor.
• Automatic Electrostatic Adsorption: Assisted installation without liquid glue and natural expulsion of residual air.

9H alumina glass and increased mechanical resistance

Made from a medium alumina glass alloy heated to high temperature, this protector benefits from a 9H structural density that neutralises everyday hazards: keys, coins, sand or rough surfaces. In the event of a violent frontal impact, its multi-layer structure dissipates the shock wave to preserve the original display from breakage and cracks.

Respecting eye-comfort technologies with 96% clarity

Honor screens integrate advanced high-frequency dimming (PWM) and blue light reduction features. The Dux Ducis tempered glass lets 96% of the light flow pass through without any parasitic prismatic refraction, ensuring your eye comfort and colour dynamics remain rigorously preserved.

Nanometric oleophobic treatment and touch glide

The outer surface receives an oleophobic layer applied by vacuum electroplating, preventing greasy substances and fingerprints from settling into the micropores of the glass. Your fingers glide with ease when typing on the virtual keyboard or browsing social media, and a simple wipe with a cloth is enough to restore perfectly crisp display clarity.

Guided bubble-free application and Case-Friendly compatibility

Thanks to its electrostatic adsorption resin, the glass automatically pushes air towards the edges as soon as it is placed on the previously degreased display. Its micrometric peripheral margin avoids any friction with the raised edges of your protective case, thereby eliminating the risk of accidental lifting.

Frequently asked questions

Does this tempered glass affect the Honor 400's eye protection features (high-frequency dimming)? No. Its mineral purity and 96% transparency do not introduce any blocking polarising filter, allowing PWM modulation and night-time visual comfort technologies to work freely.

How can I make sure no dust settles under the glass during application? Use the dust-removal stickers included in the pack just before placing the glass, preferably in a clean, poorly ventilated room (such as a bathroom after a hot shower, to limit airborne dust).

Does the glass effectively protect the screen when the smartphone is placed face down on a table? Yes. Its 0.33 mm thickness and 9H hardness create a hard physical barrier that completely isolates the original display from direct contact with the abrasive impurities of a table or desk.
