Non-contact transportation of a large-sized glass plate using air cushion for the vertical sputtering system of liquid crystal display (LCD) panel was considered. The objective of the study was to design an air pad unit which was composed of multiple injection and exhaust holes and mass flow supplying pipe. The gas was injected through multiple small holes to maintain the force for levitating glass plate. After hitting the plate, the air was vented through exhaust holes. Complex flow field and resulting pressure distribution on the glass surface were numerically studied to design the air injection pad. The exhaust hole size was varied to obtain evenly distributed pressure distribution at fixed diameter of the injection hole. Considering the force for levitating glass plate, the diameter of the exhaust hole of 30 to 40 times of the gas injection hole was recommended.

As a Joule-heat source, a conductive Mo layer was used to crystallize amorphous silicon for AMOLED backplanes. This Joule-heating induced crystallization (JIC) process could produce poly-Si having a grain size ranging from tens of nanometers to greater than several micrometers. Here, the blanket (single-shot whole-plane) crystallization could be achieved on the $2^{nd}$ and the $4^{th}$ generation glass substrate.

SRAM cell array and peripheral circuits on display panel are designed using LTPS process. To overcome low yield of SOP, high speed parallel fault detection circuitry for memory cells is designed at local I/O lines with minimal overhead for efficient memory cell redundancy replacement. Normal read/write and parallel test read/write are simulated and verified.

In this paper, we design the pattern generator circuits using PLDs(Programmable Logic Devices). The pattern generator is the circuit which generates the test pattern signal for the inspection of logical defects of semiconductor products. The proposed circuits are designed by the PLD design tool(MAX+ II of ALTERA). Also the designed circuits are simulated for the verification of the designed ones. The simulation results have a good performance.

Carbon nanotubes backlight unit (CNT-BLU) that lightened by field emission was developed into practicability. According to our novel structure, AC mode circuit design and simple printing process, CNT-BLU could achieve 85% of uniformity, 8000 nits of brightness and low material and fabrication cost. Based on these performances, this new planar backlight technology has chances to proceed to mass production and has the potential to replace traditional backlight technology because of its good properties, like the simple processes, easy to large scale, low surface temperature, low power consumption, optical film-free and Hg-free, etc.

Botanic gardens are steadily increasing based on people's increased interests in environment and ecology, lengthened leisure hours and improved transportation. However, similar florae and undifferentiated display are considered as problems, while their functions, purposes and characteristics have been more diversified. This study aims to investigate the present conditions and problems of display at botanic gardens and to find out solutions to make them exhibit plants through various ways of display and have their own characteristic, through a case study of seven botanic gardens. As botanic gardens are being recognized as a cultural institution, they should have limitations in the aspect of places that simply collect and exhibit rare plants. The current problems are unclear setting of design goals and communication with visitors. The gardens should escape from the existing supplier-oriented view to a visitor-oriented view, thinking about what the visitors will be able to see and get there. In particular, their display lacks differency, aesthetics, eye-level display, and multi-layered display. In addition to the essential functions of collecting the world's plants, exhibiting them according to purposes and giving scientific learning, botanic gardens should also show a sense of seasons with plants, trigger interests and amusement through unique plants, make visitors more interested in florae and closer to plants, and include social functions. Botanic gardens should be capable of leaning resources display, speciated display, complex and convergent garden-type display, and display fit for local and cultural contexts.

Objective: This study investigates user performance and user perceptions of dynamic Chinese text displays (Leading display and RSVP display) when users search for target information. Background: Today, information searching with dynamic displays is widely used in TV programs, on Internet advertisements, for traffic information systems, and more. Method: A human factors experiment was conducted to compare both displays. Eighteen subjects participated in evaluating two simulated interfaces for the leading display and the RSVP display. Results: The results show that the leading display was better in terms of search time and certain subjective measurements (Easiness, frustration, anxiety). The latter results are consistent with the conclusions of other research efforts showing that dynamic displays are more effective and efficient when reading information. Conclusion: The leading display is more useful for Chinese users in terms of both information searching and information reading. Application: This study helps design dynamic displays written in Chinese texts.

Because of its weak points that narrow viewing angle and grayscale inversion, 'bare' twisted nematic (TN) LCD has some limits to use as a display device, though its great strong points that low cost, high yield, simple design, high transmittance and normally white. The 'WideView(WV)' film which introduced by Fuji co., has been good solution to extend the viewing angles of TN mode, therefore that film have been used generally for TN panels needed wide viewing angle. This paper introduce the research to find the parameters of the Wide view film and a TN panel which affect viewing angle characteristics and how to adjust those parameters.
