POL has developed a number of display illumination solutions for major mobile telecoms and automotive manufacturers. Our design approach, using light scattering pattern techniques, have enabled us to provide high efficiency display illuminations with very compact space envelopes, which use the minimum of light sources and electrical power consumption.
The light scattering patterns developed by POL are laser etched on to the surface of the mould tool to provide a robust, repeatable and very cost effective means of optimising the display illumination. Alternatively, for large format displays, we have developed a novel adhesive film to give the light scattering function.
Our software portfolio includes a number of routines to generate non-uniform light scatter patterns that enable the light to be evenly distributed across the back-light viewing area. We also have our own laser equipment to cut customer back-light prototypes and soft tool inserts.
Typical applications for our back-lighting optics are LCD displays, door entry signs, advertising hoardings and ceiling lights. We have supplied back-lighting for tiny applications such as mobile phone displays, and for large format illumination such as bus shelter advertising panels. Our 3D ray-tracing software can be used to analyse the display systems and to optimise the design for maximum efficiency.
POL supply the back-light for the Nissan Juke trip computer. Our design reduces stray light to provide a sharp and bright display.
An important consideration for back-lighting is the efficiency of the light-input system. POL’s ray-tracing software can be used to analyse the efficiency of the design and optimise the performance.

The light scattering patterns developed by POL are laser etched on to the surface of the mould tool to provide a robust, repeatable and very cost effective means of optimising the display illumination.
POL has now scaled their display illumination technology from areas of a around 10 square centimetres up to 10’s of square metres for large area signage applications.
The patented technique allow large
By using POL’s thin backlighting technology developed for the mobile phone industry, the total depth of the large area signage system can be as small as 10mm and can be produced for RGB colour change.
The display illumination methods developed by POL, typically for LCD backlighting, have also been applied to the keypad illumination of mobile telecoms products and other similar applications.
Keypad lightguides of down to 0.5mm thickness are designed to give efficient light handling and even illumination intensity over the key pad area. Optical features are incorporated to manage the correct transport of the light through the keypad lightguide plane, then laser etched scattering patterns are applied to the mould tool surface to finally optimise the evenness of the keypad illumination.
This provides a very efficient, compact and cost effective solution with excellent illumination evenness.
The latest computer optical design and ray trace programs with optomechanical innovation are used to take full advantage of plastics materials. Complex optical surfaces combined with integral low cost assembly features.
SLA (Stereolithography), SLS (Selective Laser Sintering), Clear SLA, SLA to Vacuum Casting, Direct Machining and Tooling options.
Proven optical quality toolmakers are chosen and assisted by mould flow analysis to optimize the tool. Our specialist toolmakers are skilled in optical surface generation and polishing.
Our moulders are trained in the art of optical moulding. Mould flow process analysis and thorough F.M.E.A. is controlled by the Project Manager to ensure quality and quantity.
Our integrated approach to design enables optical components to become part of the total solution, including how they interface with the other non-optical components.
Plastics optical components can be coated in poly-siloxane and acrylate based resin blends to impart more robust properties.
