TFT-LCDCELL process diagrams

TFT-LCDCell manufacturing process of the array after the process, which is based on the Array front glass substrate, a glass substrate and color filter combined and inserted between the two glass substrates a liquid crystal (LC). Main processes include: cleaning, orientation film coated PI layer, friction orientation, printed plastic frame and pad printing Silver Point spray powder, assembly, cutting & lobes, filling liquid crystal detection.

First, the substrate using the lotion, brush, Character LCD Module ultrasound, IR, UV and other devices, the above remove particulates and oil, in order to ensure the cleanliness of the substrate condition.

That has formed on the substrate layer washed 500Ao ~ 1200Ao (0.05μm ~ 0.12μm) PI films uniform. By rubbing the alignment grooves on the PI film manufacturing orientation of the liquid crystal sequentially ordered.

After using the screen printing method, will be required to transfer to the CF frame plastic substrate to provide CF / ITO substrate is then necessary to make the Edge with plastic box. The agent is spread evenly spaced on the substrate for maintaining uniform spacing between the upper and lower substrates.

In stage heating, prompting the box on the CF substrate plastic softening of position after completion of the bit to impose pressure, plastic box by the CF and the ITO substrate adhesion, and finally do the right position fix, complete assembly work. The substrate assembly complete stack neatly sealed with the fixture, to impose a uniform pressure, 320x240 lcd display and into sealed with high temperature baking furnace, the substrate temperature can be maintained 150 ℃, 90 minutes or more to ensure that the sealant is fully cured spaced molding.

The completion of the assembly sealed with glass panels, according to the size of the necessary requirements to breed diamond knife, cut out the cut marks on the glass cutting / lobes.

Panel into the empty vacuum tank, exhaust after impregnation liquid crystal injection port, nitrogen breaking vacuum, using a pressure difference and the capillarity effect, so that the liquid crystal injected into an empty panel.

Attached to the elliptical polarizer on the panel below. Create contrast with its polarizing and phase difference plate compensation chromogenic make the picture clear.
