Published: January 2009

AbstractThe world's largest (15‐inch) XGA active matrix liquid crystal display (AMLCD) panel made with IGZO TFTs (W/L=29.5/4 μm) was fabricated and evaluated with the field effective mobility of 4.2±0.4 cm2/V‐s, Vth of −1.3±1.4V and sub‐threshold swing (SS) of 0.96±0.10 V/dec. for a manufacturing‐oriented process, the main factors affecting threshold voltage (Vth) of the IGZO thin film transistors (TFT) are investigated. On the glass surface, thicker regions of IGZO film have a negative threshold voltage shift. A dry etching process of molybdenum source and drain (S/D) causes negative shift of the average threshold voltage compared to wet etching in the bottom gate back channel etched TFTs. However, optimization of SiOx passivation and subsequent annealing shift average Vth positively and reduce Vth variation.

Published: January 2009

AbstractWe have fabricated 2.5″ QCIF+ bottom emission AM‐OLED with aperture ratio of 59.6% using fully transparent ZnO‐TFT array and highly conductive oxide/metal/oxide electrode for the first time. The bias stability of ZnO TFT was improved by optimizing ZnO deposition and first gate insulator process. Plasma free process for the gate insulator makes ZnO TFT very stable under electrical bias stress. The Vth shift was less than 0.3V after VDS=25 V and VGS=15 V application for 60 hours. Transparent ZnO TFT characteristics did not change noticeably under irradiation of visible light.

Published: January 2009

AbstractWe successfully fabricated GIZO (Ga2O3‐In2O3‐ZnO) TFTs with high mobility of 2.6 cm2/Vs and threshold voltage standard deviation of 0.7V which is comparable to that of a‐Si TFTs. Because conventional 5 mask process and bottom gate TFT structure of back channel etch type with channel length of 5 μm is used, it is expected to be transferred to mass production line in near future. Also we report the dependency of threshold voltage on the post process after the back surface of GIZO is exposed and suggest the effective method for controlling the threshold voltage of amorphous GIZO TFTs. Finally we demonstrate 4 inch QVGA AMOLED display driven by GIZO TFTs.

Published: January 2009

AbstractThere is a continuing demand for the reduction in power consumption, operating voltage and lengthening the lifetime of OLED's. Charge transport (hole and electron) materials (pure or doped) are an integral part of any OLED. It has been reported that nearly 60% of the total electric power is lost through the charge transport layers, nearly 36% through etl and 5.7% through eil and the remainder through, hil, htl and hbl. The life time is also critically dependent on the nature of the charge transporters employed. Thus, there is an urgent need for electron transporters with high mobility and stability. We present and demonstrate here some strategies as to the selection of appropriate materials for efficient electron transport and injection resulting in lower operating voltage, higher efficiencies and longer life‐time.

54.1: Novel Approach to Stabilize Blue OLEDs and Fabrication of High‐Efficiency Tandem White OLEDs for Large‐Area Display Applications
Authors: Hatwar Tukaram K. , Spindler Jeffrey P. 
Published: January 2009

AbstractEfficient blue OLEDs with stability similar to white OLEDs were obtained by introducing a non‐emitting buffer layer between the yellow‐ and blue‐emitting layers of the 2‐layer white OLED. This buffer layer is capable of transporting both holes and electrons. The stabilized blue OLED was then combined with another stack emitting in the G‐R region, resulting in a high efficiency tandem white OLED. By appropriate optical tuning, the 2‐stack tandem gives luminance efficiency greater than 23 cd/A at near D65 color temperature, very high operational stability, and almost no differential color change with current density or aging. These white structures can be used to fabricate low‐power full‐color AMOLED displays with excellent lifetime. Modeled performance for a 32″ OLED TV with 450 nits peak luminance with these tandem white OLEDs predicts an average power consumption of 40 W, a lifetime of 160,000 h, and color gamut of 102% NTSCx,y.
