Abstract
A method is provided for producing an illuminated graphic display composed of non-flat molded plastic backlit components which serve as interior controls for an instrument panel of an automobile. The method involves a process by which such backlit components are manufactured so as to result in minimal variability of backlighting intensity. The method particularly involves molding each backlit component from a white translucent substrate whose thickness is individually tailored such that the backlit component exhibits a suitable level of backlighting intensity when illuminated by a minimal number of light sources. For daytime viewing, a suitable and uniform level of graphics whiteness for the group of backlit components is achieved by painting each substrate with a white translucent coating, such that the backlit components have similar reflective characteristics.
