Welcome to the Pacific Northwest Chapter of SID
The Society for Information Display
February Seminar
**Virtual Event**
Microlens Array Applications to Improve Display Performance

Dr. Kenneth L. Walker
Chief Technology Officer, BrightView Technologies, Inc.

Wednesday, Feb 8, 2023, 12 - 1 PM PST 



Micro Lens Array (MLA) technology enables improved performance across a range of display applications including conventional edge lit architectures, High Dynamic Range (HDR) mini-LED displays, Head Up Display (HUD), and Virtual Reality (VR).  As a leader in Visual Intelligence™, BrightView designs and manufactures MLA solutions that leverage refraction and total internal reflection to manage optics, offering capabilities for dramatically improved performance.  This presentation will provide insight into BrightView’s unique pixel digital mastering process based on a patented grayscale photolithography system, enabling highly complex and customized designs that can be replicated onto a variety of substrates. A discussion of MLAs in display applications will focus on two case studies.  First, an overview of using a Gain Enhancement Film (GEF) to significantly improve luminance in an edge-lit back light unit (BLU) will be given.   Then an analysis of how MLA technology in mini-LED film stack architectures can improve uniformity and brightness compared to conventional diffuser films will be discussed.

        Sad News - Tom Curran


We have sad news to share – Tom Curran, lifetime SID member and former Planar employee, died on Tue / 12-June-2012.

Tom was an early employee of Planar (since 1988).  He was very active in the display community and the SID organization for many years.  He served as publications chairman for SID from 1975-82, then again from 1988-92. He got the SID President Award for his service to the organization.  More recently while in retirement Tom attended PNW-SID talks, mostly in Portland.  For people that knew Tom, it is a big loss.  He was a real gentleman and will be missed.  Tom was 85 years old and was active until the last couple of weeks.  A more detailed obituary is at "About SID" in the main SID web pages.
