Description

technical field

[0001] The patent of the present invention relates to an organic light emitting display device, in particular to a flexible organic light emitting transistor display device. Background technique

[0002] Since Dr. Deng Qingyun published an epoch-making paper on Organic light-emitting diode (OLED) devices in 1987 (Organic electroluminescent diodes, Tang, C.W.; Van Slyke, S.A., Applied Physics Letters (1987), 51 (12), 913-15.) After that, the research on organic light-emitting diode devices began to develop rapidly. Organic light-emitting diode display devices are all-solid-state devices with the advantages of thin thickness, high brightness, saturated colors, wide viewing angles, high contrast, and low power consumption. They can be used for color flat panel displays. Moreover, OLED is easy to realize flexible display, which makes it have unique advantages in competition with other display technologies, and is known as the next-generation display.
