Embodiment 1

[0022] Embodiment 1 of the present invention provides a light guide plate printing process, comprising the following steps:

[0023] (1) Provide a light-transmitting plate, the light-transmitting plate includes a light-emitting surface for emitting light and a bottom surface opposite to the light-emitting surface;

[0024] (2) Stencil production: First paste the photosensitive adhesive layer on the screen frame of the screen, design the dots, dry them with hot air at 75°C for 10 minutes, remove the base of the photosensitive film, and then print the plate, and make silk after developing. screen;

[0025] (3) Printing: Tear off the protective film on the bottom surface of the light-transmitting plate, wipe off the surface residue with alcohol, stick the bottom surface to the screen plate, pour halogen-free ink on one end of the screen plate, and adjust the inclination angle of the scraper 65 degrees, the ink part on the screen moves towards the other end, printing multiple sca...

Abstract

The invention discloses a printing process of a light guide plate. The printing process of the light guide plate includes the following steps that (1) a light transmission plate is provided; (2) a photo-sensitive glue layer is pasted to a frame of a silk screen, screen dots are designed, the photo-sensitive glue layer is dried with hot air at the temperature of 75-85 DEG C for 10-20 minutes, a film base of a photo-sensitive film is uncovered, then plate burning is carried out, and a screen printing plate is obtained after development; (3) a protection film on the bottom face of the light transmission plate is torn, the surface of the light transmission plate is wiped thoroughly with ethyl alcohol so as to remove residues on the surface, the bottom face is attached to the screen printing plate, halogen-free ink is poured to one end of the screen printing plate, the angle of inclination of a scraping and printing scraper blade is adjusted to be 65-85 degrees, all the ink on the screen printing plate moves towards the other end, and accordingly multiple scattering screen dots are printed; and (4) the bottom face, where the scattering screen dots are printed, of the light transmission plate is irradiated by ultraviolet light for 2-6 seconds, and the light transmission plate is conveyed to a tunnel furnace through a roller bed, is heated at the temperature of 85-95 DEG C for 2-4 minutes to be cured, and is cooled to the temperature of 70-80 DEG C to be thoroughly cured. The scattering screen dots printed through the printing process have the dual effects of light refraction and high light reflection, and have excellent brightness.

Description

technical field [0001] The invention belongs to the field of printing technology, and in particular relates to a printing technology of a light guide plate. Background technique [0002] As the name suggests, the main function of the light guide plate is to guide the light in the direction required by the designer, and all the light guide plates are designed to meet the needs of downstream products LCD and backlight modules, the most important thing is to achieve brightness and uniformity Spend. There are two ways to make the reflective points that make up the light guide plate: one is to form on the light guide plate body by printing (this type of light guide plate is called a printed light guide plate), and the other is to form it by non-printing (such as Engraving) is formed on the light guide plate body. After the shape processing of the light guide plate is completed, the ink is printed into reflective dots by screen printing. The material of the dots has the function...
