E-Paper Front Light
The e-paper front light guide is a light guide film (LGF) designed to provide illumination for reflective e-paper displays.
Since e-paper displays rely on ambient light to present content, a front light guide is required when ambient lighting is insufficient, helping improve readability in low-light environments.
Common applications include e-readers, e-paper smart bus stops, passenger information displays, e-paper advertising signage, and other EPD-based products.
YONGTEK offers both customized front light guide solutions and standard front light guide options compatible with selected E Ink EPD sizes, including 13.3", 28", 32", and 42". Matching LED light bar modules are also available to help customers shorten early-stage product development time and reduce design verification costs.
In addition to front light guides and LED light bar modules, YONGTEK can also provide cover glass, optical bonding, and finished product assembly services.
Customers are welcome to share their EPD drawings, product designs, and specification requirements for further discussion.
