Patent number: 7893440Abstract: A thin film transistor (TFT) array arrangement, an organic light emitting display device that includes the TFT array arrangement and a method of making the TFT array arrangement and the organic light emitting display device. The method seeks to reduce the number of masks used in the making of the TFT array arrangement by employing half-tone masks that are followed by a two step etching process and by forming layers of the capacitor simultaneous with the formation of layers of the source, drain and pixel electrodes. As a result, individual layers of the capacitor are on the same level and are made of the same material as ones of the layers of the source, drain and pixel electrodes. The capacitor has three electrodes spaced apart by two separate dielectric layers to result in an increased capacity capacitor without increasing the size of the capacitor.Type: GrantFiled: April 20, 2009Date of Patent: February 22, 2011Assignee: Samsung Mobile Display Co., Ltd.Inventors: Do-Hyun Kwon, Choong-Youl Im, Dae-Hyun No, Il-Jeong Lee, Cheol-Ho Yu
