Properties and mechanism of multi-domain vertically aligned mode on a grid surface

— Electro‐optical properties of grid‐aligned multi‐domain (GAMD) textures in homeotropically aligned nematic liquid‐crystal displays have been studied as a function of grid parameters. It is experimentally verified that with higher height and smaller pitch of the grid, a more‐stable multidomain structure can be obtained. To predict the grid properties and the mechanism of their action, both computations and experimental results are presented. The weak‐anchoring conditions are assumed in the computations on the base of the measured anchoring‐strength data to obtain more reliable parameters. A test liquid‐crystal cell has been prepared after adjusting the grid parameters, and it has shown very high gray‐level stability, a nice viewing angle, and fast response.
