china tn cob lcd module free sample

Dr Pan: Hello, Greg. COB is the abbreviation for chip on board. It is a technology, which IC is bonded directly onto PCB. COB technology is usually used in LCD module with sophisticated and complex functions.

There is a misunderstanding about COB LCD module. Since it is very stable, people would use this structure no matter what. But COG LCD module is very stable, too. It can totally replace simple COB LCD module with only display function and much cheaper for large quantity.

For the sophisticated LCD module with complex functions, COB technology may be the cheapest solution since it integrates all the components on one board and it can reduce the number of IC and board. But every coin has two sides. Even though it is very stable and there is a very small chance that it will malfunction, it will be irreplaceable if it does. There is why we recommend hybrid structure which integrate COB technology and COG technology together. It has all the merits of both technologies.

Dr Pan: Hello, Greg. TN is the abbreviation for Twisted Nematic. The main difference between TN, HTN, STN and FSTN LCD is the view angle. From the definition, the maximum view angle of TN LCD is 90°. Take this TN positive LCD for example. The view angle is 6 o’clock direction and it can be seen very clearly in the 6 o’clock direction and the front side.

Theoretically, we can add a blue film to TN negative LCD, it may look like this. Actually, from our experience, no one has done it before since HTN or STN negative LCD with blue background looks better with wider view angle.

TN LCD is the most commonly used since it is the cheapest. The maximum COM is 4, so it can’t display too many segments, and it can’t be used in the high end devices. But it performs very well in the simple display content: calculator and alarm clock.
