Abstract

The present invention relates to an organic light emitting diode display device and a manufacturing method thereof. The organic light emitting diode display device includes a plurality of organic thin film transistors, and each organic thin film transistor includes a gate, a dielectric insulating layer on the gate, A channel layer is located on the dielectric insulating layer. The channel layer includes a doping layer, the doping layer includes an organic material and a doping substance, the organic material includes one of pentacene or polytrihexyl-thiadiene pentacycle, and the doping substance includes trioxide One of tungsten or 2,3,5,6-tetrafluoro-7,7',8,8'-tetracyanodimethyl-p-benzoquinone, this organic material reacts with doping substances to generate positive charges to neutralize the remaining Negative charges in the channel layer. The OLED display device has relatively stable brightness.

Description

technical field [0001] The invention relates to an organic light emitting diode display device and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Diode (OLED), due to its advantages of high brightness, fast response, thin and short, full color, wide viewing angle range, no need for LCD backlight and power consumption, so There is a tendency to gradually replace twisted nematic (Twist Nematic, TN) and super twisted nematic (SuperTwist Nematic, STN) liquid crystal display devices, and become a new generation of portable information products, mobile phones, personal digital assistants (Personal Digital Assistant) and notebook computers A commonly used display device. [0003] Thin-film transistors in organic light-emitting diode display devices have a key impact on display quality and have been the focus of research. Generally, an organic thin film transistor has a similar structure to a crystalline silicon thin film transistor (Si-TFT), ...
