19.3: Thin Crystal Films (TCF) for LCD Color Correction
Authors: Silverstein Louis D. , Paukshto Michael V. 
Published: January 2005

AbstractThis paper describes an investigation on the application of Optiva thin‐crystal film (TCF) coatings for the correction of color errors and color variations in liquid crystal displays (LCDs). A yellow TCF polarizer coating was developed as a supplementary color correction coating for LCDs. Modeling and simulation of a normally‐white, film‐compensated AMLCD with and without the supplementary coating revealed that the yellow TCF polarizer coating neutralized the chromaticity of the display black point and dramatically reduced the migration of white point chromaticity across the gray scale range while leaving the display contrast ratio and transmission essentially unchanged. Display evaluations have confirmed the results of these simulations.

AbstractFully encapsulated passive matrix, video rate, phosphorescent OLED displays on flexible plastic substrates using a multilayer barrier encapsulation technology are described. The flexible OLED (FOLED™) displays are based on highly efficient electrophosphorescent OLED (PHOLED™) technology deposited on barrier coated plastic film (Flexible Glass™ substrate) and are hermetically sealed with an optically transmissive multilayer barrier coating (Barix™ Encapsulation). Preliminary lifetime to half initial luminance (Lo∼100 cd/m2) of order 200 h is achieved on the encapsulated 80 dpi displays using a passive matrix drive at room temperature; 2500 h lifetime is achieved on a dc tested encapsulated 5 mm2 FOLED test pixel. The encapsulated displays are flexed 1000 times around a 1″ diameter cylinder and show minimal damage.

Published: January 2005

AbstractA novel compensation scheme for correcting geometrical depolarization affects in cube polarizing beamsplitters is presented. The low cost, oblique, uniaxial birefringent components used can significantly improve system performance, e.g. the contrast of LCoS projection systems. The scheme is generally applicable to all mirror‐like beamsplitting elements whose performance can be improved by minimizing geometric polarization mixing.

Published: January 2005

AbstractThe physical image quality of two new high‐performance monochrome active matrix liquid crystal displays (AMLCDs), a 2‐ and a 5‐million‐pixel display, is reviewed. The performance is illustrated by examples (because of space limitations) of on‐axis and off‐axis characteristic curves, luminance range and contrast, luminance uniformity across the display screen, temporal modulation transfer function (MTF), spatial MTF, spatial noise power spectra and spatial signal‐to‐noise ratios. The LCDs are equipped with an internal photosensor that maintains a desired maximum luminance and calibration to a given display function. The systems offer aperture and temporal modulation to place luminance levels with more than 12‐bit precision on a desired display function and achieve uniform contrast distribution over the luminance range for a narrow viewing angle perpendicular to the LCD face. The image quality of the LCDs is compared with that of high‐performance high‐resolution cathode‐ray‐tube (CRT) displays.

Published: January 2005

AbstractA new method of color management is described which takes advantage of the high pixel density achievable with TFTLCDs. In this method, a calibration 10‐bit look‐up‐table can be loaded into the monitor and implemented as a 2×2 spatial dither block to provide a 10‐bit color palette for 8‐bit color drive. Other subpixel dithering techniques are also described for monochrome and color high‐resolution TFTLCDs. These techniques can create a very large palette, and combined with a 10‐bit digital data source to achieve precise luminance and color calibration.

Published: January 2005

AbstractWe have developed organic EL (OEL) devices, in which extremely high quantum efficiency of over 100% can be obtained. In order to generate more than one photons per injected electron, “Charge Generation Layers (CGLs)” are placed between emissive units. At CGLs, electrons and holes are generated upon voltage application, and injected to the adjacent organic emissive layers. By using one CGL and two emissive units, quantum efficiency can be doubled compared to the conventional OEL device, and using two CGLs and three emissive units, quantum efficiency can be tripled. One of the OEL device using two CGLs and three emissive units, an extremely high efficiency of 48 cd/A (ca. 14% external) was obtained, which exceeds the so‐called theoretical upper limit of 5%. Examples of such “multiphoton emission” (MPE) devices will be introduced.

AbstractBarrier ribs in the color plasma display panel(PDP) function to maintain the discharge space between to glass plates as well as to prevent optical crosstalk. Patterning of barrier ribs is one of unique processes for making PDP. In this work photosensitive barrier rib pastes were prepared by incorporating binder polymer, solvent, functional monomers photoinitiator, and barrier rib powder whose surface was treated with fumed silica particles. Study on the function of materials for the barrier rib paste were undertaken. After optimization of paste formulation and photolithographic process, it was found that photolithographic patterning of barrier ribs could be used in the fabrication of high resolution PDP.

Authors: Myers Robert 
Published: January 2005

AbstractWith the de‐facto standard “VGA” connector nearing the end of its useful life, no obvious candidate for its replacement has appeared. The recent digital interface standards have failed to gain widespread acceptance, due to their increased cost and lack of compatibility with the VGA installed base. This paper will describe a proposed new standard interface which effectively duplicates the performance of the current digital standards while retaining full backward compatibility with the VGA system.

Published: January 2005

AbstractThe proposed Motion Picture Response Time (MPRT) measurement is designed to represent and quantify the visual perception of moving images across an AM‐LCD screen. MPRT measurement method takes into account three basic LCD panel characteristics: the capacitive‐hold‐type brightness variations, brightness level dependent transition times and a liquid crystal response time. Further, MPRT figure is affected by a back light control method and video signal processing algorithms. The proposed measurement method incorporates the synchronously moving test pattern and the evaluation of the pattern edge brightness changes.

Authors: Yamamoto T. , Sasaki S. , Igarashi Y. , Tanaka Y. 
Published: January 2005

AbstractMotion picture quality of several LCDs is evaluated by both quantitative and subjective evaluation methods. In general, the value of the quantitative parameter MPRT (Motion Picture Response Time) is clearly related with the subjective evaluation, and a large value of the correlation coefficient between the value MPRT and subjective evaluation is obtained. The quality of LCDs with black insertion and over‐driving methods is better than that of LCDs without these methods, on both the MPRT and the subjective evaluation.
32.4: Two Modes of LC Parallel Alignment on the Plasma Treated Substrates
Authors: Yaroshchuk Oleg , Kravchuk Ruslan , Dobrovolskyy Andriy , Qiu Liou , Lavrentovich Oleg D. 
Published: January 2005

AbstractWe propose a new alignment procedure for liquid crystals cells that yields both zero and non‐zero pretilt. This procedure is an oblique irradiation of the bounding substrates with the directed plasma flux. As a source of plasma irradiation we use an anode layer thruster producing sheet like plasma fluxes suitable to treat large‐area substrates. Both organic (polymers) and inorganic (glass, ITO) layers can be treated. Plasma beam irradiation results in two types of LC alignment: (1) the easy axis in the incident plane formed by the direction of beam and the normal to substrate; (2) the easy axis perpendicular to the plane of incidence. By increasing the irradiation dose, one can change the alignment direction from the type (1) towards the type (2). In the first type of alignment, the pretilt angle can be controlled by changing parameters such as irradiation angle, ion current density, ion energy, etc. The second type of alignment is characterized by a zero pretilt. The azimutal anchoring energy coefficient is relatively weak (W=10−3 erg/cm2) for the first type of alignment and strong (W>10−1 erg/cm2, comparable to the rubbed polymer substrates) for the second type. The two‐mode alignment feature can be used to generate alignment with desirable parameters as well as to pattern the LC cell substrates. The method is free of certain shortcomings known for the traditional rubbing technique.
33.3: Invited Paper: OLEDs with Doped Transport Layers for Highly Efficient Displays
Authors: Pfeiffer Martin , Zhou Xiang , Huang Jingsong , Leo Karl , Blochwitz‐Nimoth Jan 
Published: January 2005

AbstractIn this paper, we discuss recent experiments which prove that evaporated organic films can be efficiently doped by coevaporation with dopant molecules. Key advantages for devices are the high conductivity and the formation of ohmic contacts despite large energetic barriers.Organic light emitting diodes (OLEDs) with electrically doped transport layers show significantly improved properties: For instance, we have achieved a brightness of 100Cd/m2 already at a voltage of 2.55V, well below previous results for undoped small‐molecule devices.The advantages of doping are even more pronounced for top‐emitting, inverted OLED structures: Due to the ohmic contacts nearly independent of the contact properties, it is possible to realize inverted top‐emitting devices with parameters comparable to standard devices. Also, it is possible to deposit ITO anodes on such devices without significant sputter damage since the active regions of the device are protected by thick doped transport layers. Our doping technology is thus a significant advantage for active‐matrix OLED displays and other displays on opaque substrate.

AbstractThermal effects on OLEDs display after full fabrication process including an encapsulation process have been studied for the longer operating lifetime of OLEDs. Time and temperature were considered as experimental factors to optimize thermal treatment. Brightness and voltage changes after thermal treatment at the optimized condition were negligible. However, the operating lifetime of OLEDs with proper thermal treatment was significantly improved.

AbstractWe present a process for active matrix flat panel display manufacture by printing polymer thin film transistors. In this process, transistors are fabricated using soluble semi‐conducting and conducting materials. Accurate definition of the transistor channel and other circuit components is achieved by direct inkjet printing combined with surface energy patterning. We have used this process to create a 4,800 pixel, 50 dpi, active matrix display. This process is in principle environmentally friendly, low temperature, compatible with flexible substrates, cost effective and advantageous for short run length and large display sizes.

Published: January 2005

AbstractIn this paper we proposed for the first time a technique of poly‐methylmethacrylate (PMMA) buffer layer insertion to overcome unsaturated output characteristics of OTFTs with cross‐linked poly‐vinylalcohol (PVA) gate insulators on a PET substrate. A 3:1 diluted PMMA buffer layer insertion resulted in saturated output characteristics and small shift of a threshold voltage in successive I‐V measurements for OTFTs due to the enhancement of surface hydrophobicity on the gate insulator. The electrical performances of a threshold voltage, a subthreshold slope and on‐off current ratio have been noticeably improved after PMMA buffer layers insertion. To our best knowledge, the highest mobility of 0.32 cm2/Vsec has been obtained among OTFTs fabricated with polymer gate insulators by spin coating processes on a PET substrate.

AbstractThick dielectric electroluminescent displays are tolerant of particle‐related defects introduced during fabrication processes compared to TFT‐LCD displays. Early experimental trials have shown that displays can have a high incidence of particle‐related defects and that a small percentage of the defects had an adverse effect on display performance or image quality. Defects introduced at different steps in the fabrication process have been characterized and their impact on the projected manufacturing yield for the displays assessed. Characterization was carried out using electrical and optical measurement techniques.

AbstractFirst results are reported on sputter‐deposition of blue emitting Ba‐Al‐S: Eu phosphors for inorganic electroluminescent FPD. Being used in Thick‐film Dielectric Electroluminescent (TDEL) devices, the phosphors exhibit EL‐luminance of about 200 cd/m2 and the C.I.E. coordinates X=0.13 and Y=0.09‐0.12 at 60 V above the optical threshold voltage under 250 Hz pulse drive. Lifetime of 2500 h at 1200 Hz pulse voltage is achieved for rapid thermal processed phosphor that is equivalent to more than 30,000 h in a TV display application.
