Abstract:
An active organic electroluminescence device back panel and a manufacturing method thereof are disclosed. The device back panel includes: a substrate, a plurality of active TFT pixel arrays formed on the substrate, and organic planarization layers, organic electroluminescence electrodes, pixel definition layers, and support bodies formed on the active TFT pixel arrays. Each of the active TFT pixel arrays includes a driving TFT and a switch TFT. The driving TFT has a gate insulation layer that has a thickness greater than a thickness of a gate insulation layer of the switch TFT. Through thickening the gate insulation layer of the driving TFT, the gate capacitance of the driving TFT can be reduced and the sub-threshold swing of the driving TFT is increased to realize well definition of grey levels.
