   4-5   Power Efficient Solutions
Many standard LCMs in the market are designed for, either, normal temperature range usage, or utilizing low power (or low forward current) LED in its backlight.

 EB-LCM can work on the following: 
- LED Modification where the application can have a wider temperature range of -40 ℃
to 85 ℃. 
- Upgrading low power LEDs that have forward current of 20~30 mA/LED to high power LEDs that have a forward current of 75~150 mA/LED. It will be coupled with a power efficient design that are adapted in industry such as automotive, industrial, aviation and more.
  5.   What Difference EB-LCM Can Offer:
         
Micro-Size dotting gives a significant improvement on backlight brightness.

Laser dotting can achieve 0.2~0.3mm diameter.
Crater shaped dots can enhance brightness by 30% more than flat dots done by silk screen printing.

    Why micro-size is better?
    1. Higher dot density makes lightguide panel much brighter.
    2. Micro-size concentrate higher energy for better brightness efficiency.

  5-2-3   Advantage: Uniformity
     To achieve outdoor legibility on standard LCM, backlight brightness must be increased to achieve over 1000 nits, brightness when measured on LCD surface. To meet this level of brightness, the prevailing market practice is to use high-powered LEDs. With conventional silk screen method of printing the pattern on the lightguide in most standard LCM, hot spots(or spot lights) can be clearly seen as a result of the LED pitch and the LED's high brightness.
​
     To fix this, EB-LCM is able to design and fabricate hot-spots-eliminating dotting patterns on the lightguide panel that corresponds to the LED pitch and shape of the LED strip.

  6.  What EB-LCM can do
        LCM Brightness Enhancement.
        Enhance standard LCM brightness of 400~500 nits become 1000 nits. With brightness enhanced to this level, outdoor application, with regards to       legibility, will be achieved.
