Light guide plate, printing ink, and manufacturing method for ink-jet printing light guide plate

Abstract

The invention discloses a light guide plate and a manufacturing method for an ink-jet printing light guide plate. The light guide plate is provided with a light incoming surface, a light outgoing surface, and a lattice point surface. The light incoming surface is located on a side surface of the light guide plate, and the light outgoing surface is opposite to the lattice point surface. The lattice point surface is provided with an array composed of a plurality of ink printing lattice points, and the intervals among the lattice points decrease along with the increases of the distances from the lattice points to the light incoming surface of the light guide plate. The sizes of all lattice points remain unchanged, or the sizes of all lattice points increase along with the increase of the distances from the lattice points to the light incoming surface of the light guide plate and the intervals among the lattice points remain unchanged. The invention also discloses printing ink for the lattice ink-jet printing of the light guide plate, and particles of the printing ink comprise PMMA or an organosilicone microballoon wrapping layer, and titanium oxide or calcium carbonate nano solid sphere particles wrapped by the PMMA or an organosilicone microballoon wrapping layer. According to the invention, the optical effect and machining efficiency of the light guide plate can be optimized.

Description

technical field [0001] The invention relates to a light guide plate, an ink and a method for making the light guide plate for inkjet printing. Background technique [0002] At present, the methods of making light guide plate dots used in LCD TVs and flat lighting include ink screen printing, thermal embossing, and laser dotting. However, traditional screen printing has a low yield rate when processing plates below 2mm and products above 55", and is far away from light. The side screen appears yellow (mainly caused by the existing ink absorbing blue light), and the investment in environmental protection is large, and the processing cost is high. The main disadvantage of the laser dotting method is low processing efficiency and high input-output ratio, which is more suitable for large-scale processing. The embossing dot process has low processing cost, and the whole process is green and pollution-free production, but there are problems such as long manufacturing cycle of embos...

Problems solved by technology

[0002] At present, the methods of making light guide plate dots used in LCD TVs and flat lighting include ink screen printing, thermal embossing, and laser dotting. However, traditional screen printing has a low yield rate when processing plates below 2mm and products above 55", and is far away from light. The picture on the side appears yellow (mainly caused by the absorption of blue light by the existing ink), and the investment in environmental protection is large, and the processing cost is high

The main disadvantage of laser dotting is low processing efficiency and high input-output ratio, which is more suitable for large-scale processing

The processing cost of hot embossing dots is low, and the whole process is green and pollution-free production, but there are problems such as long manufacturing cycle of embossing abrasive tools, high production cost, and general processing efficiency, and it is suitable for large-scale production of a single variety, and the size is limited to Within 50〞
