cob 16x2 graphic dot matrix lcd module brands

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.

Take 240*128 graphic LCD module for example. There are 240 dots horizontally, 128 dots vertically. Outer dimension 170.0×93.4 mm and active area 120.0×64.0 mm. When you develop a custom dot matrix LCD module, it can be any length and width, resolution, but it takes a lot of time and great efforts to develop it. The most widely used dot matrix LCD modules with specific sizes were made public and it is very convenient for everyone to get them with no tooling fee. You will not have a lot of options when you choose a graphic LCD module, a custom dot matrix LCD module is still your first choice.

It is a 16x2 Character Dot Matrix LCD Module which is built in with ST7066 controller IC; its default interface is 6800 4/8-bit parallel. The WH1602L1 model is negative voltage optional as well. This display is also available in SPI and I2C interface by using RW1063 controller IC. WH1602L1 is available in several different backlight colors including blue, green, white, yellow-green, amber, red, white LED. The LEDs can be driven by PIN1, PIN2, PIN15, PIN16 or A and K.
