  LED Display System (Energy-Efficient and Highly Reliable)
  This domestic LED display system minimizes excess heat generation by controlling surplus voltage dissipation, thereby achieving low power consumption, enhanced durability, and extended product lifespan.
It employs single-rank RGB LED components with uniform color and brightness, delivering clean, high-resolution images. Its high contrast design ensures vivid, ultra-bright video output even under direct sunlight or in brightly lit indoor environments, effectively capturing viewers’ attention for advertising purposes.


○ Low Power, Low Heat, High Reliability
    By applying patented high-efficiency technology to the LED display system, power consumption is reduced by up to 40% compared to competing products of the same specifications.
This enables long-term use without quality degradation through a low-power, low-heat system, significantly reducing maintenance and replacement costs.
It is the only domestic product to pass certified testing that ensures 2,500 hours of performance retention under 90-degree operating conditions.

○ Automatic Error Recovery System
    Redundant data processing applied to the LED module, along with dual backup of main data transmission and an automatic error recovery switch system, minimizes the risk of critical failures.

○ Optimal Brightness and Efficiency Relative to Power Usage
    By applying proprietary OEM LEDs developed through independently designed molds, the system achieves higher brightness-to-power efficiency compared to products using Nichia LEDs.
When measured as a unit rather than a single module, it delivers over 50% brightness without color distortion at viewing angles of 160° horizontal, 30° upward, and 80° downward.
Furthermore, it demonstrates ultra-high luminance performance exceeding the Green Certification standard by more than 250%.

  Smart Auction (Integrated Smart Display for Livestock Bidding)
  By establishing a non-face-to-face smart auction system platform, livestock auctions and listing information—previously managed individually at each local market—are now centrally managed through a secure central server.
This enhances data security and enables real-time access to livestock history and genetic information.
High-brightness LED displays present detailed information about each listed animal, including auction status and winning bids.
Additionally, the system supports both on-site and remote bidding via smartphones, delivering a transparent and modernized livestock auction experience.

  Feed Check (3D Sensor-Based Feed Inventory Management Platform)
  Using a solid-state 3D LiDAR device, the interior of feed bins (silos) can be scanned in high resolution with over 9,600 pixels simultaneously.
This enables real-time monitoring of feed inventory, prediction of depletion timelines, and analysis of consumption patterns.
By aggregating data from each feed bin, the system supports production, sales, inventory, and raw material management ultimately enhancing production efficiency and reducing labor costs..
