- Introduction
-
The SKY21-P04 rugged smart display delivers up to 1000 nits of brightness with night-vision readability below 1% nits, featuring optically bonded protective glass (GFG) and a multi-touch interface. Designed for shipboard command environments, it includes three soft-touch function keys and is built within an IP65-rated, all-aluminum enclosure to withstand salt fog, shock, and vibration. Supporting an extended operating temperature range of -40°C to 60°C, the SKY21-P04 provides reliable visual performance on the bridge, in the CIC (Combat Information Center), or in mission control spaces under harsh maritime conditions.

- Sunlight Readable Up to 1000 nits
-
The SKY21-P04 ruggedized display is sunlight-readable and performs reliably in high ambient light, including direct sunlight. Its advanced optical bonding enhances visibility by reducing reflection and improving clarity. Ideal for military operations, it ensures clear viewing in command-and-control vehicles, field deployments, mobile surveillance units, and shipboard environments, where bright sunlight and challenging conditions demand reliable performance.
- Key Features
-
(1) MIL-DTL-38999 Connectors
MIL-DTL-38999 connectors are high-performance cylindrical connectors engineered to withstand the extreme shock, vibration, and environmental exposure commonly encountered in defense and aerospace applications. Featuring removable crimp or fixed hermetic solder contacts, these connectors offer exceptional vibration resistance and reliable performance in harsh environments, including areas prone to severe wind, moisture and temperature fluctuations.

(2) G.F.G. Resistive Touch Screen
GFG touch screens are operable with fingers, pens and gloves. The glass surfaces makes the glass-film-glass sensor very durable and scratch resistant (7H).
(3) Soft Touch Buttons
The SKY21-P04 is equipped with up to three function keys, including two OSD keys and one power button, all constructed using rubber tooling for enhanced durability. Each key is large enough to allow easy operation even when the user is wearing MOPP-level protective gloves.


(4) Night Vision Mode Support (optional)
In night mode, the operator can quickly adjust the display brightness using a hardware key. The system instantly dims the screen to below 1% brightness, or switches to a customized night-vision mode, ensuring the display is safe for use with night vision devices without delay.
(5) IP65 Certified
The SKY21-P04 offers complete resistance to dust and water, delivering a rugged and reliable solution for military, ground force, and defense applications.
(6)MIL-STD 810G Compliance
The SKY21-P04 complies with MIL-STD-810 standards for shock, vibration, and wide temperature ranges. It has been rigorously field-tested to meet or exceed MIL-STD-810 requirements for extreme temperatures, humidity, shock, and vibration, ensuring reliable performance in harsh environments.
(7) MIL-461EMI Filter (optional)
The smart display is designed to meet MIL-STD-461, providing protection against vehicle and aircraft voltage surges, spikes, transients, and electromagnetic interference. This capability ensures compliance with the strictest military requirements while delivering reliable performance in harsh environments.
