Flat Liquid Crystal Display

Producers of flat panel displays are continuously pressured to provide ever-more affordable screens. To meet the need for higher pixel resolution, TFT-LCD (thin-film transistor liquid crystal display) display manufacturers, who account for over 80% of the worldwide flat panel market, must continually introduce new fabrication processes.

With the advent of the information society, display components as an indispensable part of the process of human-computer interaction, has received great attention from the state.

In the manufacturing of flat panel display, the glass substrate is firstly cleaned, and after the film is formed on the surface, the photoresist is evenly coated on the substrate, and after the process of exposure, development, etching and peeling, the graphics on the mask plate are transferred to the substrate to form the exact corresponding graphics.

In the process of flat panel display process, pollutants mainly from the manufacturing process and the handling, packaging, transportation and storage of glass substrates, the main pollutants are dust particles, fiber confetti, mineral oil and grease and other grease, inorganic particles such as silicon oxide, and residues of the preparation process, water stains, fingerprints..

These pollutants directly affect the quality and economic efficiency of the final product, so the production has to go through a complex cleaning process, and after filtration, these cleaning solutions can be discharged or recycled.


Application requirements

No media shedding in the filtration process

Filter cartridges / filters have been ultra-pure water rinsing to ensure low metal ion leaching

The end filter has good reliability and durability of impurity particle control, and the contaminants will not be unloaded when the flow rate or pressure changes

A wide range of sizes are available to ensure that the demand for filtration flow in each generation line is met.
