Brighter, Thinner Backlights
Mini LED is becoming the go-to backlight technology for new high dynamic range (HDR) LCD displays including monitors, mobile phones and tablets. The main advantage of these displays and backlight 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 displays 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 Micro Lens Arrays for Mini LED Displays
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.
Applications
- Automotive Displays
- Laptops
- Desktops
- Tablets
- 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 needs.
