Authors: Geng Di , Kim Byung Soon , Mativenga Mallory , Seok Man Ju , Kang Dong Han , Jang Jin 
Published: July 2013

AbstractWe report the design and fabrication of an amorphous‐indium‐gallium‐zinc‐oxide (a‐IGZO) thin‐film transistor (TFT)‐based high‐speed and ultra‐narrow shift register on a plastic substrate.

At the supply voltage (VDD) of 15 V, the clock frequency of the shift register approaches 166.7 kHz, corresponding to a pulse width of 3 μs. The shift register could be operated under mechanical bending radius of 2mm, making it applicable to flexible high resolution active‐matrix displays.
68.2: Invited Paper: Development of Novel Optical Bonding Process and Materials for Flat Panel Display Modules
Authors: Shinya Yoshihisa , Hayashi Kozaburo , Ogawa Koichi , Kamiyay Kenji , Toyoda Tomoyuki , Hayashi Naoki 
Published: July 2013

AbstractWe have developed Hybrid SVR™, an optical elasticity UV curable resin that improves the contrast and shock resistance of flat panel display (FPD) modules. The unique bonding process used for Hybrid SVR™ offers a number of advantages. The resin coating on the cover glass can be transformed into a pressure sensitive adhesive by irradiating it with UV light. The cover glass can then be bonded with the FPD module. This method significantly improves the process margin, which results in an overflow‐free boundary and easier thickness control. In addition, the reduced cure shrinkage results in less stress being applied to the FPD module.

Published: July 2013

AbstractBilayer nanowire gratings were fabricated by laser interference lithography. The longitudinal and lateral Surface Plasmon resonances led to transreflective polarization and color filteration, respectively. Different from the conventional absorptive polarizers and color filters, the bilayer nanowire gratings are reflective, which has a great potential in green energy display devices such as E‐papers and liquid crystal displays. Based on the optical characters of nanowire gratings, a prototype of display device without the need of conventional polarizer and colorfilter is proposed and discussed.

Authors: Roh Jeongkyun , Kang Chan‐mo , Shin Hyeonwoo , Kwak Jeonghun , Jung Byung Jun , Lee Changhee 
Published: July 2013

AbstractWe studied the effect of surface polarity of gate dielectric buffer layer on operational stability in organic thin film transistors (OTFTs). By employing four types of polymers with different polarity, we found out the operational stability of OTFTs can be improved with low‐polarity polymer gate dielectric buffer layer. With low‐polarity polymers, the devices showed good operational stability with longer relaxation time than 106 sec. Also, threshold voltage of the devices shifted less than 2 V under high gate bias stress of 3 MV/cm for two hours. Good stability may be resulted from low surface trap density as well as good grain interconnection of pentacene on low‐polarity polymer.

Published: July 2013

AbstractLED street lamps have advantages of energy‐efficient and low maintenance or long lifetime. Furthermore, single‐LED street light systems have the advantages of easy assembly and modularized optics over LED‐array ones, but of less degree of design freedom. Thus, only if the heat dissipation and optical constraint are solved, a single‐LED street light can be realized. In this study, the uniformity (max. to min. ratio) of 3.9 was achieved under a 6‐meter‐high illumination and an 18‐by‐18 m2 area, which was lower/better than that of the LED‐array ones of 7. Besides, the freeform lens efficiency of the single‐LED optics was as high as 85%.

We believe that the proposed technology can be applied to display devices, such as mobile phones and automotive displays requiring use at a low temperature.

Authors: Tan Li. , Ho Jacob Y. , Kwok Hoi‐Sing 
Published: July 2013

AbstractThe validity of combing extended Jones matrix and vectorial Fourier coefficients to characterize a complex type polarization grating (PG) at oblique incidence was proved. More specifically, the transmitted field of a complex polarization grating at oblique incidence is characterized through the extended Jones matrix. The diffraction properties of the mth order of the grating are determined by the vectorial Fourier coefficients of the transmitted field, under the Fraunhofer approximation. The measured diffraction efficiencies of a complex PG using RGB laser light show very good agreement with the calculated data.

AbstractWe report good color stable phosphorescent white organic light‐emitting diodes (OLEDs) based on double emissive layer (EML) structure composed of blue and red/green phosphorescent units. Deep hole trapping situation of red and green dopants at the red/green EML could realize less voltage dependent white spectral characteristics by restricting the change of exciton generation zone.
