What Is FPD Manufacturing Equipment?
FPD manufacturing equipment is a generic term for all equipment used to manufacture flat panel displays (FPD).
FPDs are flat, thin display devices that replace the cathode-ray tubes previously used to project images.
To manufacture these FPDs, 20 to 30 different processes are required, from designing the circuitry to testing whether the image is projected before shipment.
FPD manufacturing equipment, however, requires technology that can consistently process glass substrates at high speed and with high accuracy.
Uses of FPD Manufacturing Equipment
This FPD manufacturing equipment is placed in places where products using thin video display devices are manufactured.
When we hear about alternatives to CRTs, we tend to think of TVs, but they are used in many products other than TVs.
Examples include notebook computers, smartphones, and tablet devices.
It can be said that these products have become familiar in our daily lives because it has become possible to manufacture FPDs that are thin, light, and have high resolution.
Principle of FPD Manufacturing Equipment
There are 20-30 processes involved in the manufacturing of FPDs, but there are two major processes.
The first is the array process, which involves creating the array circuit by preparing the substrate and circuits necessary for the FPD.
This process requires a high degree of precision, as even the slightest deviation from the required array circuits will prevent them from working if there are problems with the circuits, impurities on the substrate, or if the photomasks are not firmly assembled.
Another process is the color filter cell module process, in which polarizing plates and other components are attached to the array circuit to complete the FPD.
All of these processes are performed by machine, and the equipment required is completely different.
Therefore, the technology required for each process differs greatly, and the process is quite complex.
Although the development of FPDs will not be possible without the development of technology in each process, the development of technology will enable the production of products that are more easily accepted by consumers, such as large-screen, thinner products that can be offered at lower prices.
