Authors: Coni Philippe , Perbet Jean Noël , Sontag Yves , Abadie Jean Christophe 
Published: October 2012

AbstractWhen two or more touches are detected on a self‐capacitive touch‐screen, positional ambiguities known as “ghost” touches are created.A novel method of distinguishing between real and “ghost” touches is described. Experimental results for dual‐touch give an SNR of over 55 dB, appropriate for secured touch detection in severe environments such as avionics.

AbstractOur former findings on the charge balance in blue fluorescent devices show a clear connection between the basic performance parameters: Efficiency and lifetime both show an optimum with respect to voltage. Unfortunately, for devices using a conventional hole injection and NPB as hole transport material, the optimum values do not occur at the same voltage. Moreover, the optimum voltage for lifetime is much higher than that for optimum efficiency. After investigating the underlying charge balance issues, we developed new stack layouts and hole transport materials to shift the lifetime optimum to lower voltage values. Using an appropriate hole injection layer and one of our latest hole transport materials, we can now combine excellent lifetime, low voltage and good efficiency in one fluorescent blue device. In addition, we obtain 10% EQE by carefully tuning the hole transport side in fluorescent blue devices. No special hole blocking layer is required to obtain this high efficiency.For green phosphorescent devices, we developed a thermally stable co‐host material which allows for the use of low emitter concentrations in the range of 5% without sacrificing device performance. We combine this material with an electron transporting host that shows a slight initial rise in lifetime when a low emitter concentration is employed. Due to these features, the tuning of the host mixing ratio results in excellent LT95 values in combination with good voltage, efficiency and low efficiency rolloff for high luminance.

AbstractA 10‐touch performance is achieved by using a mutual‐capacitive touch sensor. To increase the immunity to display‐generated noise, an integrator is used with the input node isolated from touch sensor panel (TSP) during the high‐LCD‐noise period, controlled by the gate‐driver clock. This increases SNR by more than 15 dB.

AbstractScanning laser projection technology is enabling advances in a number of areas of 3D display development. We discuss various scanned laser display technologies developed in our laboratory: 1) Our 1 mm × 9 mm projector uses a vibrating singlemode optical fiber to produce scanned images, and enables compact 3D head‐mounted displays with the potential form factor of a pair of eyeglasses. 2) Arrays of scanning fiber projectors can enable massively‐multi‐view autostereoscopic displays with full head motion parallax and partial accommodation cues, and 3) Our 3D volumetric displays triaxially scan light beams to render a volume, placing different pixels at different optical viewing distances to enable accurate accommodation and vergence cues.

Authors: Yang Jun‐Hyeok , Jeon Jin‐Yong , Kim Hyun‐Sik , Park Sang‐Hui , Kim Jin‐Woo , Lee Jin‐Chul , Cho Gyu‐Hyeong 
Published: October 2012

AbstractA new compensation method using current‐mode driving is introduced to solve image degradation in AMOLED displays. The proposed method can, in real time, compensate for degraded OLEDs without additional sensing lines. Moreover, there is no acceleration of OLED degradation because the method does not require an extra‐large compensation current. The conventional drawbacks associated with current‐mode driving, such as the driving speed and the channel‐to‐channel current variation, are solved with this novel technique.
51.1: Invited Paper: Optical Design of Enhanced Light Extraction Efficiency in Multi‐Stacked OLEDs Coupled with High Refractive‐Index Medium and Back‐Cavity Structure
Authors: Mikami Akiyoshi , Goto Takao 
Published: October 2012

AbstractThe light extraction of OLED has been successfully enhanced by employing high refractive index intermediate layer in the anode side and back‐cavity structure in the cathode side Back‐cavity structure consisting of semi‐transparent cathode, optical buffer layer and high reflection mirror was newly introduced to reduce surface plasmon loss in the metal cathode. The high index inter‐layer plays the role in the energy transfer from the waveguide mode to the substrate propagation mode by refractive matching between high refractive index ITO anode and the normal index glass substrate. From the results of detail optical calculation based on the multi‐scale analysis including near‐field optics, approximately 70∼80% of electromagnetic energy in the dipole emission was effectively converted to the glass and air modes by suppressing both surface plasmon and waveguide losses. The phosphorescent green light emitting device exhibits higher light extraction by a factor of 1.6∼1.7.

Published: October 2012

AbstractWe have developed a new magnetron sputtering equipment called Rotation Magnet Sputtering (RMS), and realized the target utilization rate of more than 60%. We applied this new system to the deposition of a‐InGaZnOx films. Comparison of the spatial distribution of the film characteristics between RMS and conventional magnetron sputtering revealed that film quality near erosion area is better than the rest presumably due to the heating from plasma. It was also revealed that this spatial distribution is smaller for RMS than conventional magnetron sputtering, which can be another merit of RMS.

AbstractAccording to the previous information, the stereoscopic images captured by video recorder firstly and modifying the video technology of display and these images may cause uncomfortable feeling of partial viewers. Regarding the research of eye fatigue, the variable of ambient is one of import issue. Whether the color saturation, contrast or own feeling, viewing film in the dark room is better than in the bright room. In this study, the visual fatigue is our main concern. The movie “Open Season” shows in both 2D and 3D images under various illuminations on various displays. We used questionnaires, binocular diopter, critical fusion frequency (CFF) and heart rate variability (HRV) as indexes of the visual fatigue. According to the result analysis of visual fatigue, the effect of questionnaire test was more significant than other indexes. When viewing three‐dimensional movie, is easily feel fatigue in subjectivity.

Published: October 2012

AbstractThe four‐point bend test is used extensively to measure the edge (and surface) strength of AMLCD displays both in panel form and single substrate. The subtleties of four‐point bend test for AMLCD panel applications and how one might use additional techniques, such as strain gage, finite element modeling and failure mode analysis, to better understand the data generated are investigated. This paper attempts to show the following: i) the standard four‐point bend equation (figure 1) is not applicable to thin AMLCD panels, ii) the edges and surface experience different stress, iii) stresses can be quantified by knowing break location and the appropriate strain level, and iv) failure mode analysis can support the strain analysis and provide valuable information to the experimenter.

Authors: Lim Hyun Soo , Rim You Seung , Kim Dong Lim , Kim Hyun Jae 
Published: October 2012

AbstractIn this paper, we investigated the effects of high‐pressure annealing (HPA) in solution‐processed zinc tin oxide (ZTO) thin‐film transistors (TFTs). The O2‐HPA‐treated ZTO TFTs showed higher electrical performances in aspect of an on‐current (Ion), saturation mobility (μsat) and bias stability. The O2‐HPA treatment could contribute to the elimination of defect states that originated from the oxygen vacancies in solution‐processed metal‐oxide films. The 350°C O2‐HPA‐treated ZTO TFT showed μsat, threshold voltage (Vth), subthreshold slope (S.S) and on/off ratio of 2.35 cm2/V·s, 4.36 V, 0.58 V/dec., and 1.16times107, respectively.

Published: October 2012

AbstractWe proposed a 3‐D surface profilometry with a liquid crystal (LC) phase modulator for accurate extraction of the position and depth profile. The LC phase modulator was designed to develop the dynamic fringe patterns to be operated with multi‐spatial frequencies, which were determined by changing the gap between micro‐pinholes. The amount of phase shift was controlled by changing the applied voltage. In addition, the fictitious pattern scanning method and geometrical parameters were used to reconstruct position and depth profile of an object. As a result, the depth profile of object could be computed accurately with profilometry. Also, 3‐D surface profilometry showed that integrated compact system could be constructed with the proposed scheme.
