Authors: Jung SoonShin , Kim Miok , Kim DaeYong , Lee JaeWon 
Published: July 2011

AbstractAs the LCD TV market expands, the demands for a high‐performance, high‐definition image quality and eco‐friendly products are constantly rising. The LED backlight technology is a primary case which satisfies such demands. The LED backlight can be classified as either a direct‐type or an edge‐type according to the arrangement of light sources. The direct‐type has advantage of 2‐dimensional dimming leading to a low power consumption and better image quality whereas edge‐type has advantage in the fancy design, achieving slim thickness. To achieve the slim design and the low power consumption, the edge‐type backlight unit is preferred to direct‐type. A new type of edge backlight structure is proposed with edge local dimming to achieve higher Contrast Ratio (C/R) and low power consumption in addition to the advantage of a slim thickness. A new Light Guide Plate (LGP) structure for edge local dimming was verified and lenticular LGP is proposed to obtain straight line motion of light. In addition, power consumption reduction was achieved though algorithm development. A patterned LGP production method of various concepts was examined to realize 2‐line local dimming. It was reduced 30% power consumption of all energy through 2‐line local dimming structure. And, CR improved with 14,500:1 from 1, 128:1.

Published: July 2011

AbstractBasic operation mechanisms of newly proposed reflective display mode using metal coated ball were investigated for novel electronic‐paper displays, named as Floating Metal Ball Actuator (FMBA) mode. Most appropriate structures and driving conditions were simulated by Poisson's equation solver, and the optimized cell design and driving voltage can be determined. To confirm the conducting property of floating metal ball (FMB), electrical potential of FMB directly contacted on electrode was measured by non‐contact Kelvin probe microscopy and identical with that of the contact electrode. These are useful results to apply the FMBA mode to electrical‐paper displays.

P‐140: The Ion Adsorption on SiOx Alignment Film Used for the Low Power LCDs Using Variable Frame Frequency
Authors: Huang Yi , Bos Philip J. , Bhowmik Achintya 
Published: July 2011

Abstractliquid crystal displays(LCDs) are the dominant display technology in today's mobile devices. For the battery life of mobile devices, it is very demanding to lower the power consumption of mobile displays. Operating active‐matrix liquid‐crystal displays (AMLCDs) with an ultra‐wide refresh‐rate range, down to ∼1 Hz, can lower the power consumption and offer video rate as well. It has been shown that a SiOx‐based liquid crystal (LC) alignment technique can overcome the ion problems typically encountered with low‐refresh‐rate devices because of its adsorption ability. In this paper, a further study is taken on the adsorption property of SiOx alignment film. To estimate the structure of ionic impurities in LC, a new model given constant ion concentration is implemented to simulate the voltage holding profiles, which shows that the ionic impurities adsorbed by the SiOx film are probably associated with water. Besides, it is found that adding salt into LC can help the adsorption of SiOx film, and thus lower the ion concentration in LC more effectively.
P‐142: Improvement of PDLC Performance by Changing Surface Anchoring Strength
Authors: Cui Yue , Zola Rafael S. , Yang Young‐Cheol , Yang Deng‐Ke 
Published: July 2011

AbstractWe developed a method to improve the performance of polymer dispersed liquid crystal (PDLC) display. We experimentally observed that polymer PMMA generates a homogenous alignment of liquid crystal, while polymer PIBMA generates a homeotropic alignment. By mixing them together, we were able to vary the anchoring condition and strength. We constructed PDLC by using the composite of PMMA and PIBMA as the binder. With proper polymer concentrations, the driving voltage of the PDLC can be greatly decreased.

P‐154: Natural Chiral Dopant D‐Limonene for Active Matrix Bistable Cholesteric Displays
Authors: Zola Rafael S. , Yang Young‐Cheol , Yang Deng‐Ke , Chen Heng‐Yin , Hsu Chien‐Chih , Chen Chih‐Jen , Liang Chao‐Chiun , Cheng Kung‐Lung 
Published: July 2011

AbstractWe used the Natural Chiral Dopant D‐Limonene in the recently developed driving scheme for reflective cholesteric active matrix displays. Since the scheme is based on the transition to the homeotropic state and a relaxation from homeotropic to planar, cholesteric materials with low viscosity and low elastic constants are extremely desirable. It turns out that the properties induced by D‐Limonene to the cholesteric mixture are very suitable for such a drive scheme. We show it can be used for 60Hz frame video ratio operation with better performance than a cholesteric without it.

Published: July 2011

AbstractWe used the graphene oxide (GO) as the hole transport layer (HTL) in polymer light emitting diode (PLED). Driving voltage and current efficiency of device with GO layer are 7.2 V and 5.2 cd/A, respectively. And those of device with PEDOT:PSS HIL are 6.1 V and 7.5cd/A, respectively. The driving voltage and efficiency of PLED with GO layer are much better than those without HIL. Because of its inorganic and neutrality unlike PEDOT:PSS, the PLED using a GO layer can be more stable compared to conventional PLED with PEDOT:PSS.

Published: July 2011

AbstractWe have developed a numerical fitting methodology which enables the determination of device parameters for OLEDs from impedance spectroscopy (IS) measurement, temperature dependence measurement and dark injection space charge limited current (DI‐SCLC) measurements. In our method, carrier mobility is estimated from DI‐SCLC, density of state (DOS) and interface state density are obtained from model fitting of real/imaginary part of capacitance measured by IS, barrier height of interface is estimated by modified Schottky model fitting of temperature dependence current‐voltage (I—V) measurements. Using this approach we have determined barrier heights, DOS, interface state densities, carrier mobilities and Richardson factors for each interface and layer in OLED devices. In case of the ITO/NPD interface, barrier height, DOS, interface state density and ent methods for extraction of device parameters such as carrier mobility, density of state (DOS), barrier height.1–17In these methodologies impedance spectroscopy (IS) is a useful tool for evaluating relaxation, transport and injection in various organic devices.4,9–17 Usually IS measurements allow the determination of equivalent circuits, DOS and carrier mobility of the organic semiconductor layers.In order to determine the carrier injection behaviour, we propose a numerical model and model fitting method included interface state density (Dit) for IS measurement results of hole‐only devices (HOD) and electron‐only devices (EOD). Therefore, a recombination model is also proposed for the negative capacitance behaviour of OLEDs.Naito et. al. 18have also proposed a numerical model included DOS of organic semiconductor for OLEDs. We obtain DOS from Naito's model and Dit from our model. Dit is expected to be a key parameter of the device degradation mechanism.
P‐184: Application of Deep Micromachining of Silicon Substrates to Realize a Novel Electrochromic Based Projection Display
Authors: Amirsolaimani Babak , Azimi Soheil , Mohajerzadeh Shams 
Published: July 2011

AbstractIn this paper, we report on the realization of miniaturized projection displays on silicon substrates using a highly programmable deep reactive ion etching technique. The micro‐machined silicon substrates have been used to incorporate Liionic electro‐chromic solutions. The use of tungsten oxide (WO3) in conjunction with the ITO electrodes, leads to a transparent or opaque interfaces which can be used as a method to distinguish different spots in an image, provided an external light source is exploited. The formation of highly complex three‐dimensional structures is feasible during the deep reactive ion etching of silicon wafers, while desired under‐etching is achieved by controlling the etching parameters. The evolution of cup‐like micro‐mirrors can be carried out at micrometer sizes leading to ultra‐high resolution projection systems. A passive addressing is feasible between the top ITO‐lines placed on a glass substrate and the bottom cavity‐holding substrate. By addressing individual or clusters of pixels one can achieve desired images.

P‐197: Active Matrix Touch Sensor Detecting Time‐Constant Change Implemented by IGZO TFTs
Authors: Chou Lu‐Sheng , Chiu Hao‐Lin , Lin Kuan‐Ta , Tai Ya‐Hsiang 
Published: July 2011

AbstractWe propose a novel concept of using the RC time‐constant to sense the capacitance change induced by touch and demonstrate it with a sensing circuit implemented by IGZO TFTs. The pixel circuit is consisted of one resistor and two TFTs in series, which are sequentially turned by consecutive gate pulses. By increasing the delay time of the first gate pulse waveform, a large transient ON current can flow through the TFTs while the second pulse comes, and thus become a significant sensing signal. This pixel consumes low power because the transient current only occurs when a pixel is touched.
