ABSTRACT:
An apparatus for manufacturing a printed light guide plate includes a working platform (23), and a heater (24) coupled to the working platform. A transparent slab (21) is disposed on the working platform. The purpose of coupling the heater to the working platform is to maintain the transparent slab a constant temperature in the range from about 40° C. to about 45° C., such that as few water molecules as possible are absorbed into the transparent slab. The quality of the manufactured printed light guide plate is thus improved.
