Problems solved by technology
However, no matter whether it is the first light-isolation scheme or the second light-isolation scheme, according to the current mosaic technology, there are certain defects
Mainly manifested in poor inlay quality, very strict requirements on matching dimensions, and low efficiency
Especially for the second solution, because the light guide panel and the light-insulating insert mainly rely on the bonding of adhesives, the environmental resistance is poor, and the light-insulating insert is prone to produce fine color printing and Quality problems such as cracks, light leakage, cross-light and other phenomena have caused a serious impact on the control performance of the equipment system

Embodiment Construction
[0012] figure 1 It is the principle of light guide lighting and light isolation lighting for light guide panels. pass figure 1 It can be seen that the principle of the transparent organic material light guide panel is to illuminate the light-blocking paint layer (top coat) on the surface of the light-guide panel through the light source on the lighting circuit to etch light-transmitting characters, and the light-blocking inserts penetrate in the shape of a well. The thickness direction of the light guide plate blocks the characters that need light isolation. In the figure: 1. Transparent organic material light guide panel 2. Illumination printed circuit board 3. Illumination light source 4. Transparent organic material 5. Translucent paint layer 6. Light-blocking paint layer 7. Engraved characters 8. Light-blocking insert.

The invention relates to a light-shading method for controlling a character light-emitting area of a light guide panel made of a transparent organic material. The light-shading method is characterized by comprising the following steps: smelting and welding a non-transparent organic material insert into a transparent organic material light guide panel in an ultrasonic welding mode, and realizing control over light-emitting areas, light-emitting colors and light-emitting characters on the light guide panel by using the cutting of a non-transparent organic material to a transparent material structure. The light-shading method has the advantages that the process method is simple and practical, the solidness and reliability of the insert are improved, and meanwhile the size matching requirements on inserts and light-isolating grooves of the light guide panel are reduced, the production efficiency is improved, the environmental influence resistance of a product is greatly improved, and the product quality is further improved.
Description
technical field [0001] The invention belongs to the light-shielding and light-blocking process method of an organic material light guide panel, in particular to a light-blocking method for controlling the light-emitting area of a character on a transparent organic material light-guide panel, especially for controlling the light-emitting area and color of the light-guide panel by an aircraft control. [0002] technical background [0003] The control panels of aircraft and other weapon systems need to have indicator blocks of different lighting colors on the light guide panel in order to mark different types of instruction information under night vision or low light conditions. However, due to the small space in the cockpit, in order to avoid cross-lighting between the information blocks and affect the judgment of the pilot or operator, the information blocks of the light guide panel must be designed with inserts for light-blocking treatment. At present, there are two types...
