Authors: Baik B. J. , Ryu J. H. , Cho S. J. , Jang W. S. , Park M. H. 
Published: January 2005

AbstractCurrently Plasma Display Panel (PDP) is the best promising candidate for large area digital display, especially hang‐on‐the‐wall digital TVs. Many processes have been developed to manufacture the competitive PDP. We have researched the unique process for fabricating plasma display back panel by the Low Temperature Co‐fired Ceramics on Metal (LTCC‐M) technology, which is very simple and cost effective manufacturing process. In the year 2000 we presented the evaluation results of 40′ LTCC‐M plasma display back panel and succeeded in fabricating LTCC‐M PDP module. In this paper, we present a new LTCC‐M PDP back panel on which the driver ICs are integrated by using LTCC package technology. This new PDP back panel gives us many advantages by directly integrating the driver ICs, which leads to elimination of connection parts and driver IC's circuit boards, enhancing signal speed, reducing the PDP module size and lowering the material cost.

Authors: Lee M. C. , Jung S. H. , Nam W. J. , Lee J. H. , Han M. K. 
Published: January 2005

AbstractA new polysilicon TFT has been designed and fabricated employing the air‐cavities at the edge of gate oxide in order to suppress a large leakage current and to improve the electrical stability. The air‐cavity reduces a large peak electric field near the drain due to a low dielectric constant, so that the carrier injection into gate insulator is suppressed near the drain.

P‐28: The Effect of Thermal Shrinkage on Indium Tin Oxide Coated Polyethylene Terephthalate for Flexible Display Applications
Authors: Cairns Darran R. , Paine David C. , Crawford Gregory P. , Kukureka Stephen N. 
Published: January 2005

AbstractThe shrinkage of Indium Tin Oxide (ITO) coated Polyethylene Terephthalate (PET) for flexible display applications is investigated using a Thermal Mechanical Analyzer (TMA). The effect of temperature on the resistance of the ITO coated PET was measured using a custom built 4‐wire resistance probe in a temperature enclosure. Thermal shrinkage of the substrate effects the resistance of the ITO and is temperature and substrate dependent. The shrinkage is also anisotropic with the greatest shrinkage in the machine direction. Shrinkage of up to 4% was obtained for samples maintained at 180° C. This shrinkage can greatly influence the reliability of the ITO layer and must be considered during fabrication of flexible displays.

AbstractWe present the correct method to find the optical transmission and contrast ratio for color sequential LCDs. The contrast ratio is shown to be significantly different than the static contrast ratio. We showed that the LC on and off response times, display top to bottom row write time, LED flash interval and delay times, have large effects on the color sequential CR and color shift. We also explore the top to bottom spatial variation on CR and color shift, and effects by viewing angle, gray level, LED wavelength and temperature. Methods to improve the CR and color shift are also presented.

P‐39: DVI Compliance Test Using Test Point Access (TPA) Board and Equivalent Source Board (ESB)
Authors: Sung Baegin , Lee Eric , Jang Zeehoon , Hwang Seung Ho 
Published: January 2005

AbstractThe Digital Visual Interface (DVI) specification, released in 1999, has been widely implemented by computer OEMs, monitor makers, graphics board vendors, and cable manufacturers. Silicon implementations by several chip makers are now available on the market and thus validation of their DVI implementations and compliance with the DVI specification is a critical issue to ensure interoperability between the many possible combinations of transmitter and receiver chips and boards. To that end, the Digital Display Working Group (DDWG) recently published a DVI Test and Measurement Guide in addition to presenting a rigorous electrical specification in the original DVI standard. This paper reviews the DVI electrical specification and the Test and Measurement Guide and describes compliance tests performed on customized test boards which are called the Test Point Access (TPA) board and the Equivalent Source Board (ESB).
LP‐2: High Performance LCD Backlighting using High Intensity Red, Green and Blue Light Emitting Diodes
Authors: Harbers Gerard , Hoelen Christoph 
Published: January 2005

AbstractBy using red, green, and blue (RGB) light emitting diodes (LEDs) instead of cold cathode fluorescent lamps in edge lit LCD backlights brightness and color performance (gamut) of LCD displays can be improved considerably. However: the design of an RGB‐LED backlight and electronic control need special attention: the colors of the separate LEDs need to be mixed well to obtain a good spatial color uniformity while a good balance between the red, green and blue levels has to be maintained to stabilize the white point. Additional features of an RGB‐LED backlight solution are: dynamic white point control (tune color point of backlight to LCD and/or displayed material), large dimming range, long lifetime, ruggedness, and the absence of mercury.

AbstractA two‐dimensional model is used to study the effect of cell structure on the performance of PDPs. More specifically, the effect of the insertion of a floating conducting material between the dielectric layer and the MgO film on the performance of the device is investigated. The shape of the discharge power pulse is found to be significantly different in comparison with the corresponding pulse of the standard cell geometry. It is also found that this cell structure results in a more confined discharge.

Published: January 2005

AbstractIn this paper, we propose a new structure of the priming discharge panel and the driving schemes in order to achieve high speed address driving. We inserted the priming electrode between two sustain electrode and applied the conventional driving waveform to the scan and sustain electrode, and the extra driving waveform to the priming electrode. Therefore, we realized the stable address with 1μsec data and scan pulse. This address with 1μsec scan pulse means that the single‐scan is possible in XGA or HD‐PDP and then the circuit‐cost can decrease.

Authors: Zhang Shiyong , Lu Minhua , Libsch Frank 
Published: January 2005

AbstractResidual current measurement and quasi‐static ramp I‐V method are introduced to investigate the charge migration processes in LCDs. Compared with the earlier proposed residual voltage measurement, these two methods are less environmentally sensitive, and thus, are more related to the internal charge migration process. Quasi‐static ramp I‐V measurement yields self‐consistent parameter extraction compared to direct residual current measurements. Measurement results of real LCD samples are illustrated and discussed.
8.1: New Insights Into the Degradation of Field Emission Displays
Authors: Reuss Robert H. , Chalamala Babu R. 
Published: January 2005

AbstractField emission displays can be seriously limited by the rapid current degradation of Mo field emitter arrays primarily due to poor vacuum conditions inside their thin vacuum packages. There have been a number of studies to understand the degradation mechanisms. However, we find that degradation models that have been proposed so far are not consistent with observed device behavior in a variety of gas ambients. In this paper, we present a summary of our results on residual gases inside field emission displays and the effects of these gases on emission behavior. We describe how these issues and the inter‐electrode spacing leading to local pressure buildup impact device life. We present an alternate model based on shallow ion implant to explain the device behavior.

Published: January 2005

AbstractIn this paper, we introduce an optical configuration of transflective AFLC display mode using a half‐wave AFLC cell in which in‐plane tilt angle is 22.5 °. Especially, a half‐wave cell provides very high brightness in the bright state as well as very low brightness in the dark state. The operational principles of reflective mode and transmissive mode follow those of AFLCDs and FLCDs, respectively. In case of reflective mode, it provides a high contrast, wide‐viewing angle and excellent dispersion characteristics owing to using wide‐band quarter‐wave film, and in case of transmissive mode, it also provides a high contrast and wide‐viewing angle.

Published: January 2005

AbstractTaking advantages of both low viscosity properties in LC mixture and the transient effects in Optically‐Compensated Bend(OCB) cells, we have optimized the parameters of bend cells in order to get much faster optical response than conventional nematic modes. The optimized configuration features an on‐off response time of less than 0.5 ms for a 2 micron cell driven by ±3.5 V, which is sufficiently compatible with existing electronics. Such a display as adopting this optimized device configuration is an outstanding candidate for the field‐sequential color projection applications.

P‐85: Simple Drive Scheme for Bistable Cholesteric LCDs
Authors: Rybalochka A. , Sorokin V. , Valyukh S. , Sorokin A. 
Published: January 2005

AbstractIn this paper we discuss a new dynamic drive scheme for bistable reflective cholesteric liquid crystal displays with high multiplexing level. Only two voltage levels (U and 0) are used for the addressing in this drive scheme. Addressing speed is about the time of the fast transition of a cholesteric liquid crystal from the homeotropic state to the transient planar state per line. The maximum value of using voltage is slightly overtop the critical voltage of a cholesteric‐nematic transition. These facts make this drive scheme very perspective in application for such kind of displays.
