Printed segmented electroluminescence
Printed Segmented Electroluminescence (pSEL) is a new technology (developed by UK company Pelikon) that builds on the phenomenon of electroluminescence and may have uses in flexible displays and interface technologies. pSEL Display panels use an encapsulated printed electroluminescent phosphor layer with various capacitive, insulation and conducting layers to create iconic and segmented lit areas. According to the manufacturer, the printing-based manufacturing process provides lower cost and power consumption compared to alternatives.
Devices that require multiple displays within a fixed area are most likely to benefit. Examples of current use include:
pSEL hybrid, a forthcoming development, takes electroluminescent technology a step further by offering flexible printed displays that are fully daylight visible. This opens up new markets for displays in portable products such as mobile phones, mp3 players, and car dashboards, applications that are used outdoors and need to have displays that are visible in full strength sunlight.
