It is desirable that polyimide has a stable conformation for control of the pretilt angle of LCs. Low pretilt angle (1-2 degrees) of LCs is the key issue for high duty TN-LCDs. In this paper we report the design, synthesis and properties of a series of polyimide alignment materials for LCs. The LC cells exhibit stable pretilt angle (less than 2 degrees) irrespective of curing temperature and rubbing treatment, and also show no reverse tilt disclination after thermal annealing treatment. We suggest that rigid biphenyl skeletons are the key factor for the stable conformation of polyimide alignment materials.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

For color display tubes, the brightness uniformity is one of main concerns of customers and end users. We are starting a new approach to improve the brightness uniformity. The causes of influencing the brightness uniformity include exposure correction lens (landing), exposure filter, photographic process, shadow mask design, etc. The design of the filter, which corrects the light intensity distribution in the exposure system, is the most important. We can measure 192 points for tubes' brightness distribution and black matrix hole size distribution within a certain time. From the measurement results, a new correcting filter to improve the brightness uniformity can be made by our design model. The sizes of the black matrix from the center to the edge are made almost the same as the target. Better brightness uniformity in a color display tube is realized.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display. ASID '99 (IEEE Cat.

The 50 nm PECVD a-Si film was deposited on PECVD oxide with a thickness of 300 nm. Then the samples were heated to reduce its hydrogen content and crystallized with a wide range of 308 nm XeCl excimer laser energy densities. It was found that the structure and optic characteristics of Poly-Si film is a function of the extent of crystalline of Poly-Si film. For example, in the transmittance spectroscopic range of 420-610 nm, the transmittance is dependent on the extent of crystalline of Poly-Si film. Therefore we can use these optic characteristics of Poly-Si film to monitor the extent of crystallization of Poly-Si films. Correlations between optic characteristics of laser crystallized Poly-Si, ELA energy density and surface roughness were discussed to monitor the Poly-Si film quality.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

Stringent pristine surface requirement has limited its commercial production to within a few companies, each of which uses different hot forming technique. Thermal compaction and structure relaxation studies revealed different thermal history experienced by the substrate during manufacturing. Tests shown higher expansion OA2 has less compaction than 1737 indicating a much lower sheet forming temperature than 1737. While newer OA10 and 1737 are practically inter-changeable with one another, having many similarities in their thermal mechanical properties.

When a voltage difference is applied to the electrodes, liquid crystal molecules will re-orient in different directions due to the non-uniform distribution of the electric field. This results in a 4-domain LCD with vanishingly small color-shift for viewing angle over 60 degrees in the horizontal and vertical directions. The overlapping areas of these two electrodes form a part of a storage capacitor for TFT-LCD application, which helps to enlarge the aperture ratio. The test cell results are demonstrated.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display. ASID '99 (IEEE Cat.
