Mini-LED Displays

WHAT IS A MINI-LED DISPLAY?

LED Module with High-Brightness Local Dimming Technology

Mini-LED technology sets a new standard in display performance by offering precise control over local dimming zones, which enhances contrast and delivers striking image clarity. This breakthrough enables deeper blacks and brighter visuals, making Mini-LED displays a powerful choice for outdoor applications, even under direct sunlight. With their high brightness and vivid picture quality, these displays excel in installations on yachts, vehicles, motorcycles, and other outdoor environments where optimal visibility is essential.

Engineered for durability and superior performance, Mini-LED displays maintain outstanding clarity and readability in even the most challenging conditions. Their robust design ensures consistent, high-quality viewing experiences, providing a perfect blend of resilience and display excellence for any demanding outdoor setting.

Traditional LCMs
with traditional backlight
  • Traditional LCDs typically have low transmittance levels (around 5 – 10% per layer), leading to poor color saturation when displaying dark or black images due to the backlight’s high brightness.
  • Additionally, higher power consumption in traditional LCDs can cause overheating issues and result in a shorter lifespan.
Mini-LED Displays
with Mini-LED as backlight
  • Our new LED module complements the LCD by serving as the backlight.
  • When displaying lighter-colored images (white or gray), the Mini-LED backlight enhances brightness.
  • Conversely, for darker-colored images (black or brown), the Mini-LED backlight dims or emits no light, resulting in deeper blacks and stronger contrast.
  • This dynamic backlighting mechanism ensures that dark areas appear darker and light areas appear brighter, ultimately delivering clearer images with superior contrast.

How Local Dimming Works
Higher brightness level: up to 5,000 nits (Sunlight Readable)

Based on customers’ needs, the number of LEDs placed in each area varies, ranging from 1 to 16 LEDs in each zone.

  • Determine how many blocks are needed based on the size of the LCD.
  • One board can have from 1×8=8, 2×8=16,… up to 8*48=384 zones.
  • If the LCD is large, two boards can also be connected in series.
  • Up to 4 boards can be connected in series with a total of 1536 bits.

High Contrast Ratio: 1:1,000,000

  • With regional dimming, the effective brightness of each area can be adjusted to up to 4096 levels.
  • By converting the RGB color scale of each zone into a brightness level, the television can adjust the amount of light emitted by each zone to present different brightness levels and achieve better color contrast.
  • The color contrast can be from 1:10 to as high as 1:1,000,000

Low Power Consumption: 30% – 50% Power Reduction

  • When the LCD is black or dark, local dimming can effectively reduce the brightness or turn off the LED to save unnecessary energy. 
  • Depending on the color of the content displayed, the energy can be effectively saved by 30 – 50%.

Lower Temperature : < 50°C

  • Driving method of an LED display uses a dynamic scanning technique, specifically the 1/8 DUTY SCAN scanning method.
  • Most of the time the LED light is only 1/8 of the time, and other zones are also scanning and the brightness is only partially illuminated, the overall power consumption is quite low.

Long Lifespan : 50,000 hours

Given the fact that the driving method is using the 1/8 DUTY SCAN scanning method and most of the time the LEDs are partially illuminated, the overall power current and power consumption would be much lower, and the lifespan of the LEDs would be extended. MTBF reaches more than 50,000 hours.

Challenges for Outdoor Advertising Screens

Outdoor advertising screens typically have a brightness of 1000 to 1500 nits to improve visibility under sunlight. However, increasing the backlight’s brightness can lead to low color saturation and high power consumption, requiring additional cooling mechanisms. Local dimming Mini-LED backlight LCD modules can address these issues by enhancing brightness, reducing power consumption, and prolonging the product’s lifespan.

Solutions for Outdoor Advertising Screens

Local Dimming Mini-LED Backlight
  • Local dimming Mini-LED backlight technology enhances brightness while reducing power consumption.
  • Provides up to 3000 nits of brightness, which is 3 times higher than traditional outdoor advertising screens.
  • Mini-LED backlight LCD modules have a longer lifespan due to the low heat generation, which reduces the need for additional cooling mechanisms such as fans.
