Abstract

A dot arrangement structure of a light guide plate having high light exiting uniformity. The dot arrangement structure comprises a light guide plate; two opposite edges of the light guide plate are light inlets (101); a scattering surface (102) of the light guide plate is provided with dot matrixes (103); from each light inlet (101) to the symmetrical centerline of the light guide plate, 1st-155th dots with the diameters gradually increasing are sequentially arranged in the longitudinal columns of each dot matrix (103). An optimal value is obtained for each dot by means of measurement of a goniophotometer. From each light inlet (101) to the symmetrical centerline of the light guide plate, the diameters of 1st-155th dots gradually increase in sequence, and the reflecting surface also gradually increases; thus, the light exiting uniformity is high, and the light exiting efficiency is high. A light guide plate, at two sides of which light is emitted, formed accordingly has optimal uniformity and optimal light exiting efficiency.
