Performanceanalysis and optimization of fringe field switching with negative dielectric liquid crystal
In order to achieve good performance of liquid crystal display (LCD) with wide viewing angle
the transmittance and response time of negative fringe field switching (FFS) mode are analyzed and optimized. To achieve high transmittance of the FFS mode
the parameters is analyzed and selected by simulation. The results of simulation analysis and optimization are verified by experiments and the parameters affecting the transmittance and response time are discussed. Compared to FFS mode with positive dielectric liquid crystal (LC)
the transmittance of negative LC is increased by 18% through optimization
the response time is comparative (26 ms). Under the same conditions
the highest transmittance is reached when the transmittance curve integral of the whole pixel area is the biggest. The pixel pitch of FFS with negative LC is confirmed in this way. In addition
the response time is determined by slit angle and cell gap
and not relevant with pixel pitch or electrode width-space ratio (
