With the development of technology, flat panel displays have become an indispensable part of people's lives. As one of the key components, the transmittance of polarizing film directly affects the display effect and user experience. Therefore, accurately measuring transmittance and evaluating its performance is crucial to ensure the quality of flat panel displays.
What is transmittance?
Transmittance refers to the degree to which light is absorbed, refracted or scattered when passing through an object, usually expressed as a percentage. In flat panel displays, the transmittance determines the brightness and clarity of the screen display, which directly affects the user's viewing experience.
Test Methods
In order to accurately measure the transmittance of flat panel display polarizing films, standardized testing methods need to be followed. First, the instrument is preheated to reach a stable state, and then the sample is placed on the sample test rack for spectral scanning and the monomer transmittance is measured. Then, the parallel transmittance and orthogonal transmittance are repeatedly measured to obtain the transmittance at different light wavelengths. Finally, single-wavelength transmittance and UV isolation performance are measured to obtain complete optical performance data.
Value
Through the measurement of transmittance, the optical properties of polarizing films can be evaluated, including transparency, polarization and other indicators. This data is of great significance for the design, production and optimization of flat panel displays. High transmittance polarizing film can improve the brightness and clarity of the screen, improve the user's viewing experience, while also reducing power consumption and extending the service life of the device.
Transmittance is one of the important parameters for evaluating the performance of flat panel display polarizing films, and its accurate measurement is crucial to ensuring product quality and user experience. In an increasingly competitive market, only through scientific and reasonable testing methods and strict quality control can we produce flat panel displays with excellent performance to meet the growing needs of users.
