Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixtures, and particularly relates to an optical film measurement fixture. Background Art
[0002] Optical films refer to thin film materials with certain optical properties and functions, which are widely used in various display devices, optical instruments and other fields, mainly used to change the propagation direction, intensity, polarization state and other properties of light.
[0003] The polarizer belongs to a kind of optical film. The core principle of the polarizer is to use its special molecular structure and material properties to only allow polarized light in a specific direction to pass through and block polarized light in other directions. It is commonly used in the liquid crystal display field, such as display screens, mobile phone screens, etc.
[0004] Regarding the detection categories of polarizers, there are generally polarization degree tests
[0005] The polarization degree is one of the key indicators to measure the performance of the polarizer. Use a professional polarization degree measuring instrument to measure the transmission and blocking ability of the polarizer to light with different polarization directions to determine whether its polarization degree meets the standard requirements. Insufficient polarization degree may lead to problems such as blurred display effects, color distortion or light leakage.
[0006] High temperature and high humidity test
[0007] Place the polarizer in a high temperature and high humidity environmental test chamber, set certain temperature and humidity conditions (such as temperature 60°C, humidity 90%RH), and keep it for a certain period of time (such as 24 hours, 48 hours, etc.), and then take it out to check whether its performance and appearance have changed.
[0008] Weather resistance test
[0009] Use weather resistance test equipment to simulate the use of polarizers under natural environmental conditions such as long-term light exposure, temperature changes, and climate changes. By exposing it to specific light, temperature, and humidity cycle conditions, observe whether the optical performance, appearance, etc. of the polarizer have changed.
[0010] In a variety of test items, they all require a fixture for clamping and placing the polarizer. In the prior art, due to the thinness of the polarizer, the fixture is likely to deform the polarizer when clamping it, affecting the measurement results. Utility Model Content

[0018] In the above technical solution, the optical film measuring fixture provided by the utility model has the beneficial effects of:
