Abstract: The response surface model of the cell gap on the polymer substrates for the flexible Liquid Crystal Display (LCD) processes was investigated using statistical approaches. The D-optimal design is carried out to build the experimental runs considering the design space and the cell gap was characterised by the quadratic statistical models. The Analysis of Variance (ANOVA) technique was used to analyse the significance level among the factors. In addition, the desirability function for searching the specific conditions for the desired response was used for the design-space optimisation.

Keywords: cell gap; D-optimal design; response surface methodology; RSM; desirability; flexible LCD; liquid crystal displays; polymer substrates; ANOVA; statistical modelling; design space optimisation.
