RiTdisplay starts OLED production

RiTdisplay has been a proponent of OLED display technology for several years and even though they are a few years behind Samsung and LG they are now ready to start mass producing OLED panels for small handheld devices such as smartphones.

RiTdisplay’s first OLED panel is a 3.5-inch AMOLED (active matrix OLED) panel with 320x480 pixel resolution. The panel is targeting at high-end mobile phones.

RiTdisplay produce OLED displays using the a-Si (amorphous silicon) method – contrary to the p-Si (polycrystalline silicon) method that LG and Samsung are using. In short this means the conductive layer that supports TFTs (thin film transistors) is created on a substrate (typically glass) using a different – and cheaper - process. It enables RiTdisplay to produce cheaper OLED panels but on the other hand they cannot achieve as high brightness, resolution and response time as OLED panels produced via p-Si (often called LTPS).

RiTdisplay says that they have buyers for the 3.5-inch OLED panel. However, they refused to say who these buyers were.
There is high demand for OLED displays in the market but supply is still very limited.
