In this paper, we introduce a useful composite layer, comprising hole‐transporting materials with molybdenum oxide. By using the composite as a buffer layer on an anode, an OLED with low drive voltage can be obtained, and pixel defect formation can be effectively suppressed.

A folding screen type OLED display was developed (Fig. 1) to demonstrate the application of a flexible display. The display surface can be bent with a curvature radius of 4 mm. To protect an OLED against moisture, inorganic passivation layers are provided on the upper and lower sides of the flexible display. Using our transfer technology, dense passivation layers can be obtained. The measured water vapor transmission rate of the layer is 7 10 6 g/m 2 day or less, which improves OLED reliability.

-In this study, a 5.9-inch foldable active-matrix organic light emitting diode (AMOLED) display was developed. A folding test was performed repeatedly. The display survived the folding test (100,000 folds) with a curvature radius of 2 mm. To protect an organic light emitting diode (OLED) against moisture, inorganic passivation layers are provided on the upper and lower sides of the flexible display. Using our transfer technology, high density passivation layers can be obtained. The measured water vapor transmission rate of the layer is 7 × 10 À6 g/m 2 Áday or less, which improves OLED reliability.With these techniques, we have developed a book-type display, which is repeatedly foldable like a book, and a tri-fold display including a display area, which is foldable in three.

Our results indicate that estimates of mean nuclear volume are prognostically superior to morphological grading of malignancy, such as Gleason score and WHO classification, in prostate cancer.
