Problems solved by technology

With respect to the printed backlight technology, refer to an ink-printed light guide plate disclosed in Chinese patent ZL03240962.1, which discloses that at least one of the upper and lower surfaces of the light guide plate is printed Refraction and reflection units are formed by printing ink, and each refraction and reflection unit is in the form of an array as a whole; and then the printing ink absorbs light and then diffuses outward through refraction and reflection. The uniformity of light emission cannot be guaranteed, and the light transmittance of the existing printed ink-based light guide plates has not been improved accordingly. Therefore, in order to suit the development of light guide plates in the future, how the industry can improve the light transmittance of light guide plates and ensure uniform light emission is particularly important. important

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] see figure 1 , figure 2 As shown, a printed ultra-thin light guide plate includes a transparent plastic plate 1 with high light transmittance, wherein:

[0020] On the upper surface 11 of the plastic plate 1, a plurality of colorless printing ink layers 12 forming folding and reflecting units are arranged in arrays, which are made of nano-materials and inks with micro-particles to form astigmatism through silk screen printing or pad printing. Pre-realization; each printing ink layer 12 is gradually densely arranged on the side of the plastic plate 1 close to the incident light source 2 along the direction away from the incident light source; each of the above-mentioned printing ink layers 12 is correspondingly covered with another light-curable colored printing material containing nano-materials The ink layer 13, the color printing in...

Abstract

A printed ultra thin light guiding plate comprises a plastic cement plate (1) with high transmissivity. On at least a surface of the upper and lower surfaces of the plastic cement plate are provided with a plurality of printed ink layers (12) in an array for forming refractive and reflective units. On each printed ink layer (12) is covered correspondingly with a printed ink layer (13) which is optical curable and comprises nanometer material.

Description

technical field [0001] The invention relates to a light guide plate for a backlight system, in particular to an ink-printed ultra-thin light guide plate. Background technique [0002] Today, with the rapid development of electronic / communication products such as mobile phones and household appliances, the light guide plate is widely used in the liquid crystal display (Liquid Crystal Display LCD) of various electronic / communication products. Cathode tubes or light-emitting diodes) generate light sources, which are guided by the light guide plate to generate outgoing light. [0003] Generally speaking, the backlight manufacturing process includes printing and non-printing. The non-printing method uses molds to directly form or press to form light guide lines. This technology has nothing to do with this application, that is, it will not be described in detail here. With respect to the printed backlight technology, refer to an ink-printed light guide plate disclosed in Chinese ...
