MULTI-INNO Technology is a leading manufacturer of small and medium size display modules which includes monochrome LCD and LCM displays, TFT displays, resistive and capacitive touch panels, same as passive matrix OLED displays.
All of this is possible thanks to the “bistable” E-paper technology, which at the same time allows for an image content to be maintained without any energy consumption. Current is only needed for changes in the content of the E-paper display. Another feature of E-paper displays is the reflective operation. Familiar from LCDs, the impinging light is reflected by the polarizer, which then creates very good legibility, as with a paper print, in sunlight. Consequently E-paper displays don't need energy-hungry background lighting.
The millions of small microcapsules inside an E-paper display, filled with positively charged white particles and negatively charged black particles, depending on the electrical field imposed, are represented as white or black. Moreover, as a supplement to the black particles, E-paper displays are also available with additional red pigments.
