BrightView Technologies has launched its new Polycarbonate Brightness Enhancing Films (BEFs), based on its micro-lens-array (MLA) technology. The new display film can increase brightness by up to 30% for high performance display designs. Target applications include desktop monitors, laptops, tablets and other custom displays. The company will showcase the new display film and MLA stacks at the Society for Information Display’s (SID) Display Week 2024.

BEFs are used in edge-lit and mini-LED LCD display applications. BrightView’s BEFs use a high-quality polycarbonate substrate, combined with the company’s edge-lit and mini-LED MLA stacks, to maximize brightness and efficiency. The two-film solution helps increase output from the backlight and minimize power consumption of the display, BrightView said, making it suitable for a range of emerging automotive, augmented reality, virtual reality and aerospace applications.
Polycarbonate has a number of advantages over polyethylene terephthalate (PET), Scott Thorley, BrightView’s vice president of product and program management, told Electronic Products. “It is stronger and more impact resistant, can withstand higher temperatures, has better dimensional stability over a wide range of temperatures, and offers better optical clarity.”
Each of the materials target applications that meet their price and performance requirements. “PET is generally less expensive than polycarbonate, so it can be used in less demanding environments, but for applications like automotive and aerospace, you want a more durable substrate like polycarbonate,” Thorley said.
In the automotive market, almost everything is becoming a screen from the center dash screen and instrument cluster to the head-up display and now rearview mirrors, he said. “With more and more electric vehicles on the market that need maximum range, which is driven by the battery, BEFs allow for brighter displays with lower power consumption.”
Brightview BEFs are designed to be used in conjunction with its portfolio of display film solutions. These display film solutions incorporate the company’s MLA technology that consists of microscale lenses to manage and shape light. The MLAs use refraction and total internal reflection to manage optics and provide better light uniformity and local dimming performance, compared to conventional diffusers that use light scattering, the company explained. The company also uses a roll-to-roll manufacturing process for cost effective and high-volume production.
BrightView collaborates with customers to design and size the right solution for their applications. “When customers are designing new displays, they have a lot of variables to consider, including spacing (or pitch) of the LEDs, thickness of the display, power consumption and many others,” Thorley said. “BrightView has a team of optical experts that are familiar with these tradeoffs and work closely with customers to optimize the display design for maximum efficiency within the design envelope.”
BrightView will showcase its latest display films and MLA solutions at Display Week 2024, San Jose, California, May 14-16, at booth #445. The company also will host a presentation, “BrightView’s Advanced Edge-Lit and Mini-LED Display Film Solutions,” May 14, at the Exhibit Hall Center Stage.
