illustrate two such convex forms for the cured excess filler deposits 66 in fig1 12 the convex shape extends beyond and surrounds the second via opening 44 in fig1 15 the convex shape is approximately limited to the area of the second via opening 44 through different shapes or configurations the visible light passing through the filler material 50 may be altered to produce a different visual appearance or effect to the user similar to altering the shape or configuration of a lens as another example fig1 18 illustrate instead of a concave or convex shape a flush fill that is an embodiment where the filler material 50 is flush with the surface of the second or front side 18 the cured filler material 50 and front side 18 from the method 10 results in protected vias 30 capable of transmitting light through panel 12 the use of vias and an optically transparent filler material produces a smooth and continuous panel surface to the naked eye that is capable of displaying controlled images through the vias from interior illumination as shown in fig1 fig1 illustrates a panel 12 including a back light 70 which may be an led fluorescent or incandescent light or other lighting devices panel 12 may be a section inserted into a housing or may be an integral section of the housing 72 as shown in fig1 the resultant panel 12 can be used in all manner.
