Method for fabricating light guide plate

A method for fabricating a light guide plate, the method comprising:

• injection molding a light guide plate to obtain a light guide plate with a stub;
• cutting away the stub to obtain a light guide plate with a cut edge;
• providing a thermal resetting apparatus having an nano release material layer and a stainless steel substrate, the nano release material layer firmly adhered to a surface of the stainless steel substrate, a thermal melting temperature of the nano release material layer being higher than that of the light guide plate;
• heating the thermal resetting apparatus such that a temperature of the nano release material layer is higher than the thermal melting temperature of the light guide plate, but lower than the thermal melting temperature of the nano release material layer;
• and
• treating the cut edge of the light guide plate by contacting the nano release material layer of the thermal resetting apparatus with the cut edge of the light guide plate to obtain a light guide plate with a smooth edge at the original cut edge portion.
