How is Molybdenum Oxide Used on the Screen?
Molybdenum oxide (also known as molybdenum trioxide) is a colorless or yellowish-white powder, which soluble in water slightly and soluble in acid, alkali, and ammonia solution completely.
Molybdenum oxide layer has been widely used in the modern graphic screen because of its low optical reflective, no matter it is reliable for subpixel separation, or a way of covering conductors with or prevent unnecessary reflection from ambient light.
Narrow frame display: covers the conductor
Modern desktop monitors and large TV screen abandoned plastic edge (narrow) framework, which not only improved the appearance, also made the condition of a few screens together to form a large screen come true. But the high reflection molybdenum, aluminum or copper conductor on the TFT glass will be exposed when there is no plastic frame. Molybdenum oxide antireflective coating solved this problem, it will reflect less than 6% of the incident light (550 nm), so as to make the conductor invisible.
OLED: a collection of reflector and electrode resistance
TFT metal molybdenum layer (the source/drain) reflects the ambient light falling on the OLED display so as to reduce the contrast of the monitor. A circular polarizing filter like this used to reduce unnecessary reflection. Although the reflection from the electrode reduced, the light output of the monitor also reduced. So molybdenum oxide is the ideal of TFT substrate metallization of reflector since it absorbs light very well, and it is also an electrical conductor.
The metal molybdenum can reflect about 60% of the incident lights; this value is greater than 6% of the same thickness of the molybdenum oxide layer. OLED manufacturers eliminate polarization by using a molybdenum oxide layer.
Touch screen anti-reflective coating
Molybdenum oxide PVD film can prevent unnecessary reflection between the metal surface (metal bridge) with capacitive touch sensors.
