CHINA’S FLEXIBLE GADGETS GO INTO OPERATION

China’s first flexible display production line will go into operation next year, making bracelet shaped mobile phones and folding tablets, according to BOE Technology Group on Wednesday.

AMOLED (active-matrix organic light-emitting diode) is a display technology used in smart watches, mobile devices, laptops, and televisions. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and actively refers to the technology behind the addressing of pixels.

 

BOE will invest 46.5 billion yuan ($6.99 billion) on its 6-generation AMOLED (active matrix/organic light-emitting diode) production line in Chengdu, Sichuan Province in southwest China.

An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that has been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.

 

Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for passive-matrix OLED operation.

TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies,polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays.

 

AMOLED is new technology, physically flexible with a fast response, high contrast and wide visual angles, compared with traditional LCD panels.
