The Switchable Privacy Light Guide Plate (SP LGP) is a specialized light guide plate that enhances safety, security, and privacy—key elements in modern display technology.

Traditional Backlight Units (BLUs) are opaque and capable of supporting only a single viewing angle.
However, MEMSLUX’s SP LGP is transparent and can independently function as a BLU with different viewing angles.

By stacking two BLUs with distinct viewing characteristics, the system enables smooth switching between two display modes:

• Public Mode, which allows for easy content sharing, and

• Privacy Mode, which restricts side viewing to protect personal information.

This innovative approach makes it possible to dynamically switch between viewing angles depending on the user's needs, offering a flexible and advanced solution for display applications.

Unlike conventional backlight components used in the LCD industry, the Switchable Privacy Light Guide Plate utilizes a transparent single light guide plate to enable a dual-layer structure.

Traditional light guide plates rely on multiple optical films—such as reflectors, diffusion films, and prism films—to control light distribution.
In contrast, MEMSLUX’s light guide plate employs 3D micro-patterning technology to precisely shape the light path and adjust the light distribution.

This approach allows for the design and fabrication of transparent light guide plates with wide viewing angles, offering a thinner and more efficient alternative to conventional backlight systems.

Additionally, advancements in automotive display technology are leading to the development of very large displays that extend to both the driver's and passenger's seats. Passengers can enjoy various entertainment activities through the display without disturbing the driver's view, ensuring safety. When the vehicle is stopped, the display in the passenger seat can be shared with the driver.
