Abstract: Embodiments relate to a method of forming an organic light emitting diode (OLED) display device. A first inorganic layer, a first organic layer, and a second inorganic layer are formed on pixel regions of an OLED display device. At least part of a first inorganic layer is formed using atomic layer deposition (ALD), such that the first inorganic layer completely covers particles generated on the OLED. Embodiments also relate to an OLED display device with pixel regions, each pixel region including an OLED, a bank layer across a boundary between adjacent pixel regions, and a first inorganic layer on at least a portion of the OLED and the bank layer. The first inorganic layer includes a first inorganic sub-layer and a second inorganic sub-layer.

Abstract: Disclosed herein are an OLED display panel further including a switching transistor for controlling application of supply voltage in the initializing interval of a pixel, an OLED display device including the same, and a method for driving the same. The OLED display panel avoids a short-circuit between supply voltage VDD_EL and reference voltage Vref to thereby reduce initialization voltage applied to the gate terminal of the driving transistor T_dr. The OLED display device can achieve various effects such as improved response characteristics of pixels by reducing deviation in the initial voltage used in sampling.
