Sanayi System Co. provides various simulation platforms for display panels. TechWiz OLED provides the light extraction efficiency of OLED's structure. TRCX calculates the capacitance and resistance characteristics of panels. TSolidX is software specialized for creating CAx formats such as polygon, triangle, and tetrahedron meshes (ANSIYS, IGES, Abaqus, STL, etc.). TDeformX provides display panel deformation analysis results due to external forces. Also, it outputs RC results and 3D meshes of the deformed structure through interworking between programs. TVolumeX analyzes the injection quantity of LC and the optimized design and density of column spacers in LCD panels. TechWiz LCD 1D, 2D, and 3D are the best software programs for optical design and analysis including diffraction phenomena of LCDs.
