Abstract

The invention provides a printing-free light guide plate structure. The structure comprises a light guide plate body; the light guide plate body includes a light input surface, a light output surface and a bottom surface, wherein a light beam is guided into the light guide plate body via the light input surface, the light input surface is placed in the lateral portion of the light guide plate body, the light beam is guided out of the light guide plate body via the light output surface, and the bottom surface of a planar structure is opposite to the light output surface; multiple spherical projections which are molded with the light guide plate body in an integrated manner are arranged at the light output surface in an array, the spherical projections in the array are arranged in rows and columns in a staggered manner, and the spherical projections are made of a PMMA material; and the diameter of each spherical projection ranges from 180 to200 micron, the height of the spherical projection ranges from 135 to 150 micron, and the spacing between the adjacent spherical projections in each row / column ranges from 225 to 250 micron.

Description

technical field [0001] The invention relates to a non-printing light guide plate structure for a liquid crystal display. Background technique [0002] In recent years, with the colorization and enlargement of liquid crystal displays, their application fields are more extensive, such as notebooks, various desktop computers, and LCD TVs. Because the liquid crystal itself does not have luminous properties, therefore, the display effect is not achieved. It is necessary to provide a light source system as the light source of the display, such as a backlight module. The backlight module mainly includes a light guide plate, a light source, a reflector and one or more optical films. Among them, the light guide plate is an important component in the backlight module. It is used to guide the transmission direction of the light beam emitted from the light source, convert the line light source or point light source into a surface light source, and is used to display the brightness of th...
