Mini LED

LED Module with High-Brightness Local Dimming Technology

Cons of Traditional LCD:

Most modern LCDs have a transmittance of around 5 - 10% for each layer

When the display is used in dark or black conditions, a backlight with high brightness in an LCD can lead to a poor color saturation

Higher power consumption causes overheating.
Higher power consumption; Shorter lifespan.

Pros of Our New LED Module:

The mini LED works with the LCD as the backlight.
When showing lighter-colored images (white or gray):

Mini LED backlight increases the brightness of the LCD.

When showing darker-colored images (black or brown):

Mini LED shows relatively low brightness or no light

Makes the dark darker and the light brighter. Stronger contrast and clearer images.

Why LCM embedded MINI LED Backlights better than light guide panels?

HIGHER - brightness level: up to 5000 nits
HIGHER - contrast ratio: 1:1,000,000
LOWER - power consumption: 50% reduction
LOWER - temperature: 40°C
LONGER - life span: 50,000 hours

Higher brightness level: up to 5000 nits
Sunlight readable

Local dimming:
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 1x8=8, 2x8=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 : 40 degree 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 life span : 50,000 hour

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.
