Method for testing abrasion resistant performance of mesh spot of light guide plate

Abstract

The invention relates to a method for testing the abrasion resistant performance of a mesh spot of a light guide plate. According to the method for testing the abrasion resistant performance of the mesh spot of the light guide plate, firstly, the light guide plate is subjected to high temperature aging, and a high temperature aging method is used for simulating the state of the mesh spot of the light guide plate which is used for a long time; and secondly, friction force is applied on a testing spot which is selected on the light guide plate, the testing spot of the light guide plate is rubbed back and forth, and then whether the testing spot is normal is tested. Through the testing of the abrasion resistant performance of the mesh spot of the light guide plate after the light guide plate is used for the long time, the problems that the adhesive force of the mesh spot of the light guide plate is lowered after a long time use, the mesh spot is not resistant to abrasion and prone to fall off, the abrasion resistant performance is poor and the like can be found, and therefore the good abrasion resistant performance or the poor abrasion resistant performance of the mesh spot of the light guide plate can be tested out, the problems that the mesh spot falls off, is bad, is poor in abrasion resistant performance and the like after the long time use can also be tested out, products with the problems that the mesh spot of the light guide plate may mutate so that the light guide rate of the products is poor, light passing through the light guide plate is not even and the like can be sorted out effectively, and a basis can be provided for sorting out high quality light guide plates for the development of the products.

Description

【Technical field】 [0001] The invention relates to a method for testing the dots of a light guide plate, in particular to a method for testing the abrasion resistance of dots of a light guide plate. 【Background technique】 [0002] The light guide plate is widely used in the fields of backlight module technology and light box lighting. The bottom surface is printed with light guide dots by UV screen printing technology. The optical grade acrylic sheet is used to absorb the light emitted from the lamp to stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition by the light guide plate. Front shot. The light guide plate is a product that transforms a linear light source into a surface light source, and the light guide network plays a key role in the process of transforming a linear light source into a surface light source. [0003] Light guide pl...

AI Technical Summary

Problems solved by technology

After long-term use of the dots of the light guide plate, the adhesion of the dots may decrease or even peel off, resulting in poor light guiding effect of the light guide plate, and the uniformity of the surface light source cannot meet the use requirements. The industry has no problem with the poor wear resistance of the dots of the light guide plate after long-term use. There is no effective test method, it is impossible to test the wear resistance of dots, and it is impossible to test the quality of light guide dots after long-term use
