Abstract
A light guide plate structure includes a light transmissive layer, which has a plurality of light guide points and/or brightness-improving holes used for altering a light route in the light transmissive layer. Each of the light guide points has a size within a range from 0.01 mm to 0.1 mm. The light guide points are distributed to form a plurality of regions corresponding to predetermined key locations. The distribution density of the light guide points in the light transmissive layer where the larger transmissive light intensity is received is smaller than that in the light transmissive layer where a relatively small transmissive light intensity is received. The distribution of the brightness-improving holes is in accordance with the brightness of transmissive light, where the sum of circumferences of all brightness-improving holes in a relatively dark region is greater than that in a relatively bright region.
