In which application scenarios is it necessary to add AG, AR, and AF to LCD displays?

Adding AR (anti-reflective), AF (anti-fingerprint), and AG (anti-glare) treatments to LCD displays is primarily to improve display performance, durability, or user experience under specific lighting conditions. Simply put, AG (anti-pus light) solves the problem of "pus-like light reflection", AR (anti-reflection) solves the problem of "visible under strong light", and AF (anti-fingerprint) solves the problem of "oil-stained fingerprints".

The following are specific application scenarios and selection logic:

1. AG (Anti-glare)

Primarily converts specular reflection into diffuse reflection to eliminate glare.

• Outdoor equipment: Such as ATMs, automatic ticket vending machines, and charging stations, preventing large white spots from appearing on the screen under direct sunlight, thus avoiding the inability to read the seconds.

• In-vehicle displays: Dashboards and center console screens, preventing strong light from creating reflections on the screen and interfering with driving safety.

• Education and office: Whiteboards and conference room displays, ensuring viewers are not disturbed by overhead light reflections.

2. AR (Anti-reflective)

Through coating, light interference is eliminated, significantly improving light transmittance and contrast.

• Outdoor handheld devices: Ensures clear visibility of mobile phones, tablets, and smartwatches in sunlight (rather than simply increasing brightness).

• Medical instruments: Monitors and surgical displays require high contrast and accurate color rendering.

• High-end commercial displays: Window displays and museum showcases prevent reflections from affecting the viewing of exhibit details.

3. AF (Anti-fingerprint)

A fluorine coating is applied to the surface, making the screen smooth to the touch and resistant to smudges, while also being easy to wipe clean.

• Touchscreen devices: Mobile phones, tablets, touchscreen laptops (frequent swiping by users).

• Wearable devices: Smartwatches (close to the skin, easily attracting sweat).

• Public health facilities: Medical equipment, self-service ordering machines, facilitating frequent disinfection and cleaning without leaving residue.

Composite Processes

High-end applications often require layered functions:

* **AG+AR:** Commonly used in automotive dashboards. First, a matte finish eliminates human shadows (AG), then a coating enhances clarity (AR), preventing the matte finish from causing screen fogging.

* **AR+AF:** Used in outdoor mobile phones, it reflects strong light (AR) while preventing oil and dirt from obscuring the image (AF).

* **Triple A (AG+AR+AF):** Used in marine and aviation displays, simultaneously meeting the requirements of anti-glare, high light transmittance, and easy cleaning.
