High Level, High Technology

-Company Intro

Backed by over 50 R&D and engineering experts and more than 100 professionals,

HI LED delivers next-generation LED solutions that can be installed on curved, spherical, and

transparent surfaces—where traditional displays fall short.

[ LED Element: 3× Contrast Ratio ]

Verified capsule-packaged Black LED
High-grade LED chips for crisp, vivid image reproduction
Black LED technology delivers superior contrast and color clarity compared to conventional white LEDs
Supports colors closer to true primaries than standard SMD LEDs

Low Contrast Ratio vs High Contrast Ratio

White LED Chip vs Black LED Chip

[ LED Element: “Colors Closest to Nature” ]

The colors of LEDs are based on the three primary colors of light, which combine to produce white.
By blending these three native LED colors, the display reproduces hues that are closest to natural tones.

[ LED White Balance ]

White balance refers to the precise white point located at chromaticity coordinates x = 3.1 and y = 3.1 on the CIE diagram. This point serves as the “white center” reference. An LED chip’s ability to accurately reproduce this reference white determines overall color uniformity; if the white balance is off, color distortion will occur. In low-cost LEDs whose white balance is not properly calibrated, color reproduction is prone to the kinds of distortions illustrated below.

[ Refresh rate ]

High refresh rate (≤ 3,840 Hz)
Enhanced video clarity reduces eye strain
No line flicker even when filmed with a broadcast camera at a 1/3,840 s shutter speed

Refresh rate: ≤ 3,840 Hz

Refresh rate: ≤ 900 Hz

[ Drive IC ]

Utilizes a PWM Drive IC
Exceptional grayscale accuracy and rapid refresh rates
Maintains high grayscale performance even with brightness changes below 30%

100% Brightness
