Embodiment Construction

[0019] The present invention aims at the problem of whether the ink peeling off of the light guide plate will cause the light guide effect of the light guide plate to deteriorate, the uniformity of the surface light source cannot meet the use requirements, and there is no effective test method for the long-term use of the light guide plate. It provides a test method for the ink adsorption performance of the light guide plate method.

[0020] The present invention will be described in further detail in conjunction with the accompanying drawings and embodiments.

[0021] figure 1 It is a flow chart of the method for testing the ink absorption performance of the light guide plate in one embodiment, including:

[0022] Step S120: Increase the temperature of the incubator, and place the light guide plate in the incubator to conduct a thermal test.

[0023] In this embodiment, the temperature of the incubator was adjusted to 65 degrees Celsius, and the thermal test time was 100 ho...

Abstract

The invention provides a light guide plate printing ink adsorptivity test method. The method comprises the following steps: rising the temperature of an incubator, and carrying out thermal test on a light guide plate in the incubator; carrying out temperature stress testing on the light guide plate; scratching the printing ink surface of the light guide plate; carrying out light guide plate printing ink adsorption test; and carrying out printing ink appearance quality check on the light guide plate. The disadvantages of low adsorptivity and likely peeling of long-term used light guide plate printing ink can be found through the adsorption test of the light guide plate printing ink stimulating high temperature ageing and hot and cold impact, problem products can be effectively screened out, and a basis is provided for the selection of high-quality light guide plates for product exploitation.

Description

technical field [0001] The invention relates to a test of optical equipment, in particular to a test method for the ink absorption performance 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. light ink. Use the optical grade acrylic sheet to absorb the light from the lamp, and form total reflection on the surface of the optical grade acrylic sheet. When the light hits each light guide ink, the reflected light will spread to all angles, and then destroy the reflection condition by The light guide plate is projected from the front. The light guide plate is a high-tech product that transforms the line light source into a surface light source. The light guide ink plays a key role in the process of transforming the line light source into a surface light source. [0003] Light guide plates have been widely used in various industries. Factors affecting the quality of lig...
