Under the premise that quality is guaranteed, it will reduce production costs including reduction of costs of raw materials and improvement of production and managerial efficiency.

TFT LCD Module QC Process

The LCM is actually the "back-end" production process of liquid crystal displays. it has three steps:

Step 1:

the LCD liquid crystal finished panel (Cell), anisotropic conductive adhesive (ACF), driver IC, flexible circuit board (FPC) and the PCB circuit board are pressed together by a machine.

Step 2:

Assemble the finished product together with the backlight board, light source and iron frame;

Step 3:

Aging treatment.

1. Visual Testing after COG/TAB

2. Electron microscopes up to 500 times magnification can reveal every liquid crystal molecule

3. Check whether the glass substrate conforms to the specifications, including: glass thickness, size, flatness and other projects. In addition, the glass must be inspected for scratches, shadows or any changes in the surface.

4. Check the unevenness (Mura) on the front and back of the color filter with the poor color rendering of the sodium lamp.

5. It has been tested for temperature and humidity, as well as pressure resistance and impact resistance.
