Technical Field

The invention relates to a light guide plate microstructure embossing press with constant pressure, and belongs to the technical field of light guide plate processing equipment.

Background

The light guide plate is the optical plate who installs on advertising light boxes or display screen usually, choose for use the board of optics level, a plurality of leaded light points of array processing on this board, when using, light is penetrated into along the direction that the leaded light face extends by the edge of light guide plate, reflection and the refraction of a plurality of leaded light points on the light guide plate, light after reflection and refraction is via each angle diffusion, then light is openly jetted out by the light guide plate, when seeing from the front of light guide plate, whole light guide plate is penetrating.

The light guide plate is manufactured in a printing mode and a non-printing mode, and the traditional method for manufacturing the light guide plate mainly adopts the printing mode, namely, printing materials containing high-divergence light source substances (such as silicon dioxide and titanium dioxide) are utilized and properly distributed on the bottom surface of a blank light guide plate, internal propagation caused by total reflection effect is damaged by the property of the printing materials absorbing and diffusing the light source, and a light path is changed, so that the light source is guided to be emitted from the other side and uniformly distributed in a light emitting area.

Disclosure of Invention
