Toshiba and Idemitsu Kosan develop new Organic LED panel
A new small-molecule Organic LED panel for mobile equipment has been jointly developed by Toshiba Matsushita Display Technology (TMD) and Idemitsu Kosan.
The two companies claim that the Organic LED panel has a 30 times longer lifetime and uses one tenth the power consumption of current TMD models.
TFT substrate design technology and TMD element design technology was used to develop the panel.
The organic LED display has a 2.2 inch QVGA (240x320) format which can be used for mobile equipment applications.
It has a power consumption of 100mW, with this total based on typical movie screen images, defined by 30 per cent brightness of a full white screen.
The luminosity half-life is 60,000 hours based on a full white screen at 200 cd/m2.
Idemitsu developed materials for the panel including RGB light-emitting materials and peripheral materials which provide both low-power consumption and high efficiency.
Both companies were involved in the joint evaluation of the optimum combination of materials.
