A Hybrid Boundary Element and Analytical Method for Calculating the Wiring Resistance in Liquid Crystal Display Panel

Aiming at the deficiency in accuracy and efficiency of the finite difference method (FDM) and boundary element method (BEM) when calculating the wiring resistance in a liquid crystal display (LCD) panel, a hybrid boundary element and analytical method for the resistance calculation of twodimensional LCD wiring is proposed.The method decomposes the LCD wiring into segments of“long edge”and“corner”shapes.The analytical method is used to calculate the resistance of“long edge”, while BEM is employed to calculate the resistance of“corner”.A concave polygon partition method is also proposed to improve the accuracy of BEM.The experimental results show that, the hybrid method is able to calculate the resistance of LCD wirings in actual designs accurately, with the computational speed over 10000X faster than FDM and BEM.The proposed method has been applied to the design and verification of LCD panel.
