Development of 1-pL inkjet heads improves display panel quality, indicating advancements in manufacturing technology.
This paper reports on the development of 1pL inkjet head and G8.5 equipment for 350ppi display panels. Firstly, we have derived the margin of 350 ppi pixels. Then we allocate margins to each key mechanical component and develop the 1pL inkjet printheads with 1.0pL ± 2.4% volume variation and ±1.35 μm landing position repeatability.
