  • We report the improved AMOLED with a-Si TFT backplane based on our unique structure. Our new structure is called Dual-plate OLED Display (DOD). It can also achieve not only higher uniformity of luminance in large-sized display due to low electrical resistance of common electrode but also wider viewing angle.

  • We developed a novel growth method of CNTs on metal substrate for device applications, deposited by a triode direct current plasma enhanced chemical vapor deposition (dc-PECVD). With resist-assisted patterning (RAP) method, we had grown CNTs on metal substrate, which were strongly bonded with metal substrate.

  • We report single and two-stacked WOLED. Two-stacked WOLED structure adopts fluorescent blue EML and phosphorescent (red+green) EML. Current efficiency, EQE and color coordinate of two-stacked WOLED are 54.5cd/A, 28.8% and CIExy (0.322, 0.345), respectively. Those of single WOLED are also 20cd/A, 10% and CIExy (0.29, 0.37), respectively. Dual-plate OLED Display (DOD) employing the single WOLED shows high aperture ratio up to 67% in 2-inch panel of which pixel size is equivalent to that of 32 inch Full HD.

  • In this paper, we propose English word display interfaces to improve short-term memory: a basic display, a rotation change display, a size change display, and a color change display. Using these display interfaces, we apply the word recall memory test to users. Experimental results show that the users recall more English words in the rotation change display and the color change display, as compared with the basic display and the size change display. Also, the users think that the rotation change display and the color change display are more helpful for short-term memory than the basic display and the size change display. It describes that the word display interface can have an influence on short term memory.

  • In this work, we provided a novel test method to verify the sealing materials for flexible LCD cell. The ultraviolet type curing sealing material with low process temperature was suitable for LCD cell assembly. We also proposed the sealing materials which passed 13200 times bending test within 20 mm curvature.

  • Depending on the optical design method, a novel dual-mode transflective LCD with proper LC material and optical films was developed. The design increased the optical transmittance and the reflectivity of dual-mode transflective LCDs with the proper parameters of cell gap, alignment layer and optical films. These parameters were evaluated by computer simulation. The simulation results also revealed that the transmissive and reflective states presented similar performance in the transflective LCDs.

  • We demonstrated 4 inch QVGA AMOLED display driven by GaInZnO TFT. The structure of GaInZnO TFT is back channel etch (BCE) which is conventional structure for a-Si TFT. The electron mobility of GaInZnO TFT is $2.6\;cm^2/Vs$ and Vt is 3.8V. It is thought that GaInZnO TFT could be backplane for AMOLED TV.

  • A novel single cell gap transflective liquid crystal display was developed. By using the ink jet printing technology, we fabricated a transflective liquid crystal display with the hybrid alignment in the reflective region and the homogeneous alignment in the transmission region. Compared with the traditional technologies, our technology provided the advantages of easy process, high yield, fast throughput, and less material usage. We also applied this technology to the 2.4 inch prototype. This panel could be implemented in the handheld product applications.
