Abstract
Official abstract text for this publication.
The present invention provides a light guide plate and a backlight module containing the light guide plate. The light guide plate includes a plate body and a coating layer formed on the plate body. The plate body includes a bottom face, a top face opposite to the bottom face, and a plurality of side faces between the bottom face and the top face. The coating layer is formed on at least one side edge of the top face. The coating layer has a refractive index that is greater than or equal to 1 and less than refractive index of the plate body. The light guide plate uses the coating layer formed on the top face to reflect light back into the light guide plate to confine the light within the light guide plate so as to prevent light leakage and ensure light intensity and homogeneity of the light guide plate.
