Automobile instrument liquid crystal display light guide plate

The invention discloses an automobile instrument liquid crystal display light guide plate which comprises a plate body. The plate body comprises a light entrance surface with light incident from side and a light exit surface with light emitted from the front. Rows of scattering dots with same size and shape are distributed on the light exit surface. The scattering dots of two adjacent rows are arranged alternately. The shape of the scattering dots is a regular polygon. The center distance between the circumcircles of any two adjacent regular polygons is three times of the radius of a circumscribed circle. According to the invention, the scattering dots in the shape of a regular polygon are arranged on the light guide plate; the light scattering effect of the light guide plate is greatly improved; and the light guide plate has the effect of uniform brightness. 本发明公开了种车用仪表液晶屏导光板，包括板体，板体包括光从侧面入射的入光面和从正面射出的出光面，出光面上布满多行尺寸形状相同的散射网点，相邻两行的散射网点交错排布，散射网点的形状为正多边形，任意两个相邻正多边形的外接圆之间的圆心距为外接圆半径的三倍，本发明通过在导光板上设置正多边形的散射网点，大大增加导
