Screen printing plate, light guide plate, display equipment and manufacturing method of light guide plate

Abstract

The embodiment of the invention relates to the technical field of display and discloses a screen printing plate, a light guide plate, display equipment and a manufacturing method of the light guide plate. By the adoption of the screen printing plate, the light guide plate, the display equipment and the manufacturing method of the light guide plate, tracing of the production information of the light guide plate can be achieved, and accordingly the production control difficulty of the light guide plate is lowered. The screen printing plate comprises a screen printing plate body. The screen printing plate body comprises a screen point printing part corresponding to the light guide plate to be printed. The screen point printing part comprises at least one production information mark printing area, and each production information mark printing area comprises a plurality of printing marks. A covering piece is arranged for each production information mark printing area, and the covering pieces are detachably connected with the screen printing plate body and cover selected printing marks in the production information mark printing areas.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a printing screen, a light guide plate, a display device and a manufacturing method of the light guide plate. Background technique [0002] Among flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, and occupies a dominant position in the current flat panel display market. . [0003] Backlight module is one of the key components of TFT-LCD. Its basic principle is to convert point light source or line light source into surface light source with high brightness and good uniformity, so that the LCD panel can display images normally. The structure of a backlight module usually includes: a backplane, a light source, a reflector, a light guide plate, an optical film, and a plastic frame. [0004] As the main optical component of the backlight...

Problems solved by technology

[0005] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: in the traditional light guide plate printing process, since a printing screen can be printed in multiple batches, the light guide plate often takes a long time to print. The production of the light guide plate is based on the same printing screen design, and the production date and production line of the light guide plate cannot be tracked, which makes the production control of the light guide plate more difficult.
