36.3: Development of 192‐Output SOI PDP Address Driver IC with Over Temperature Detection Circuit
Authors: Fujiwara A. , Takasugi K. , Hosokawa A. , Takahashi K. 
Published: January 2005

AbstractWe have developed 192 outputs PDP address driver IC, uPD16347 with the over temperature detection circuit. This IC uses bonded SOI wafer and trench process for dielectric isolation. This IC has the 0.5μm design rule CMOS logic circuit and 80V high withstand voltage CMOS output circuit. Also, this IC uses the TCP that is expected to become the mainstream of package technology for future PDP address driver IC. However, it is difficult to use TCP for PDP address driver IC because of large power dissipation to drive PDP. Therefore we have developed the over temperature detection circuit for this product. By using this function it becomes possible to detect the over temperature condition of the driver IC.

Published: January 2005

AbstractPolyimide containing the chalcone moiety is expected to show the high photodimerization rate and stable alignment characteristics. We introduced the chalcone moiety as a side chain into the polyimide backbone to apply to the photo‐alignment layer. The photochemical reaction with the tilted incident light produced out‐of ‐the plane orientation of chalcone side chain. The orientation effects align the LC in LCD, which possesses the various pretilt angles depending on the length of side chains.

AbstractRed emitting borate‐based phosphor is currently used in the manufacturing of PDPs as a red component. The color purity of these phosphors is poor due to an orange line in the emission spectrum. Efforts are being made to develop a better phosphor and replace the existing borate phosphor. In this presentation, luminescence characteristics and morphology of red emitting trivalent europium activated rare earth oxide, vanadate, borate, phosphate phosphors and their complexes are presented. The life (stability) of these phosphors in a PDP panel are also presented. The suitability of these phosphors in PDP applications is discussed.

Authors: Small Jeffrey A. , Ludden Christopher A. 
Published: January 2005

AbstractThe application of TFT displays for handset applications requires new display system architectures in order to achieve desired power targets and to enable handset features such as integrated cameras. There are significant benefits to embedding a framestore into the source driver chip of a handset display system. This paper explores these benefits with respect to typical handset usage models, power consumption, memory architecture, camera/video functions, and other advanced techniques for display power optimization. In particular, both the system power consumption and the source driver interface bandwidth requirement will be greatly reduced. These and other benefits are discussed, and the architecture of a TFT handset display system incorporating such an embedded framestore is described.

Published: January 2005

AbstractLow temperature process technologies for high‐performance polycrystalline Si (poly‐Si) thin‐film transistor (TFT) fabrication are discussed based on a key word — “interface”. Reduction of localized defects at two types of interfaces, namely grain boundary in poly‐Si film and gate SiO2/Si interface, successfully achieves high‐performance poly‐Si TFTs with average n‐channel mobility of 315 cm2V−2s−2, threshold voltage (Vth) of 0.86 V and subthreshold swing (S) of 143 mV/decade with small variations (1σ) of 30 cm2V−2s−2, 0.05 V and 6 mV/decade, respectively. This result indicates that control of “interface” is the key to the next generation high‐performance poly‐Si TFT fabrication.

47.3: Reliability of Transparent Conducting Substrates for Rollable Displays: A Cyclic Loading Investigation
Authors: Gorkhali S. , Cairns D. R. , Crawford G. P. 
Published: January 2005

AbstractFailure mechanisms for flexible conducting substrates are investigated in the context of rollable/flexible display applications. Cyclic loading experiments (substrates subjected to multiple cycles of tensile strain) were carried out on both ITO coated PET and PEDOT:PSS coated PET substrates. The resistance was measured after each bending cycle. The resistance increased with number of cycles and was not reversible. Even if the tensile strain on the ITO/PET was below the virgin cracking threshold (∼2%) previously reported [APL 76, 1425 (2000)], slight increases in resistance were measurable after just a few cycles.
47.4: Effect of Glass Thickness on Stress in a Centrally Loaded LCD‐TV Panel
Authors: Gulati S. T. , Helfinstine J. D. , Bayne J. F. , Lapp J. C. 
Published: January 2005

AbstractAn analytical solution, based on linear plate theory, shows that the maximum tensile stress in an LCD‐TV panel loaded at the center and simply supported at the four edges depends on several independent factors, namely i) glass thickness, ii) nature of the load, whether static or dynamic, iii) constraints on the center deflection, and iv) details of the cell structure, such as the size, spatial density and properties of the cell spacers and their response to the load. In the case of static load, a thicker panel will experience higher stresses than a thinner panel for identical values of center deflection. In the case of dynamic load, i.e. impact by a spherical ball, the thicker panel will also experience higher stresses than a thinner panel for identical values of center deflection. Experimental data based on strain gages and fractographic analysis of fracture origins are in progress to examine the pros and cons of thick vs. thin glass panels from a mechanical durability point of view. Dynamic loading can induce higher stresses than static loading and hence is a more sever test for mechanical durability.

AbstractWe have improved a white color balance using multi‐grating period structure in the holographic backlight units that can be applicable to mobile LCD panel where several LEDs are placed at edge of guide plate as light sources. New H‐LGP is based on the characteristics of grating and its diffraction angle can be determined by specific grating period. With this idea, hologram backlight unit can realize not only lower weight and less power consumption but also higher light utilization by eliminating couple of prismatic sheets which have been widely used in conventional unit inevitably.

Authors: Kim Sun Wook 
Published: January 2005

AbstractA new mass production line for Organic Light‐emitting Diode (OLED) display is designed to overcome obstacles of current operating lines. We adopted in‐line operating scheme instead of usual cluster one to the line for more flexible processing options and so easier line expansions or modifications. By utilizing linear‐2type sources and substrate transporting carriers, thickness uniformities of different organic layers evaporated are well controlled within 2% over the area of 200 mm × 230 mm. We also attached glass‐can encapsulation system instead of usual metal‐can one to the line for faster processing time and better processing reliability. As the result, the TACT time of this new line is about 3.5 min. An OLED module fabricated is introduced.

54.2: A High Dynamic Range Display Using Low and High Resolution Modulators
Authors: Seetzen Helge , Whitehead Lorne A. , Ward Greg 
Published: January 2005

AbstractWe have developed an emissive high dynamic range (HDR) display that is capable of displaying a luminance range of 10,000cd/m2 to 0.1cd/m2 while maintaining all features found in conventional LCD displays such as resolution, refresh rate and image quality. We achieve that dynamic range by combining two display systems — a high resolution transmissive LCD and a low resolution, monochrome display composed of high brightness light emitting diodes (LED). This paper provides a description of the technology as well as findings from a supporting psychological study that establishes that correction for the low resolution display through compensation in the high resolution display yields an image which does not differ perceptibly from that of a purely high resolution HDR display.
54.4: Toward a Touch‐Sensitive Display Wall
Authors: Morrison Gerald , Holmgren David 
Published: January 2005

AbstractNearly all existing passive touch screen technologies are not suitable for very large format displays. However, one touch technology, a machine vision system, can scale from small display formats to very large display formats including wall‐sized displays. When very large displays are touch enabled, multi‐user collaboration and the ability to detect pen or finger contact are desirable functions. Again, existing passive touch technologies other than a machine vision system cannot accommodate these needs. This paper presents an update on the development of a machine vision touch display technology that was first introduced at SID 2001. This update addresses the ability of this technology to have multiple simultaneous users, to detect the size and approximate shape and orientation of the object touching the display, determine whether the object is a finger, pen, or eraser, and to work with variety of display sizes.
