||In this study, we developed a new process of to improve their flexibility by UV carving and hot-embossing forming technology. The main purpose was improving the plastics substrate manufacture and impact its stress resistance in order to maintain the value of spacer gap, which can keep original optical property and durability, and improving the mechanical property by adding silicon dioxide.
The purpose of this research is to develop a new process for flexible panel by laser carving and hot-embossing forming technology, which make a micro-structured spacer. Influences of UV-photoinitiator content, spin-coating speed, molding pressure, and silicon dioxide content on the micro-structured spacer of flexible panel were studied. Results showed that UV-photoinitiator content of 3.0 wt% in spacer material got the optimum UV-curing condition and the mechanical property of it was increased by adding of silicon dioxide.
The transmittance of spacer material by increasing of spin-coating speed increased from 74 % to 85 % and then the transmittance of it in molding pressure of 250 psi achieved 89 %. From SEM analysis, the coating thickness of spacer material by increasing of spin-coating speed decreased from 13.1 ± 0.3 μm to 2.5 ± 0.4 μm. From stylus profiler analysis, the average spacer height achieved 6.2 ± 0.3 μm. Besides, the micro-structured spacer of flexible panel possessed good stress-resistance and flexibility. In this research, this new process not only got a great improvement the cell gap of micro-structured spacer in the flexible panel, but possessed electro-optical display ability.
