Technology
JDI has developed several technologies to differentiate its LCD panels from those of the competitors.
- Active-matrix displays driven by TFTs based on a low-temperature polycrystalline-silicon ("LTPS") process instead of amorphous silicon. These higher performance transistors allow a higher resolution (more ppi = pixels per inch).
- Most LCDs manufactured by JDI use the In-Plane-Switching concept, as do many of its competitors. JDI has developed an improvement for darker black pixels (true-black appearance), called "IPS-NEO", which reduces the light shining through from the backlighting.
- The conventional combination of a transparent touch-screen device in front of an LCD panel has been replaced by integrating the touch-screen function into the LCD panel itself, called "Pixel Eyes".
- For reflective LCDs without backlighting, JDI has developed an addressing technique using a thin-film memory device SRAM in addition to the conventional TFT for each pixel, so that a still image can be stored with very little energy.
