Brighter, Thinner Backlights 

Mini LED is becoming the go-to back light technology for new high dynamic range (HDR) LCD displays including monitors, mobile phones and tablets. The main advantage of these displays and back light units (BLUs) is localized dimming, where individual LEDs in the BLU can turn on and off to create the much higher contrast ratios required to support HDR compared to edge lit LEDs. Mini LED backlights offer several distinct advantages over existing Edge lit and OLED technologies including:

  • Local dimming for richer contrast and darker blacks
  • Lower power
  • Ultra high brightness
  • High reliability and no burn in (compared to OLED displays)

BrightView MLA Products for Mini LED Display

Creating a highly uniform light output from an array of LEDs that is thin, efficient, and cost effective is challenging. Instead of using conventional diffuser films that rely on light scattering, BrightView uses micro lens array, or MLA, films to provide improved performance. Instead of scattering, MLAs rely on refraction and total internal reflection to manage optics resulting in:

  • Better light uniformity and local dimming performance
  • Thinner film stack
  • Improved efficiency
  • Work with color conversion films to minimize crosstalk.

  • Specialty and custom displays

How to choose a BrightView product for edge lit displays

BrightView offers variations on the gain enhancement film depending on the application and type of edge lit back light. Things to consider are:

  • LGP light design (light extracting features and backside linear structure)
  • Crossed BEF choice (BEF prism refractive index and prism apex angles) 
  • Reflector properties (specular to diffusive)
  • Crossed BEF orientations

Our experienced team of optics engineers can help guide you through the design process and find and create the optimal configuration that fits your need.
