Tutorial: Dr Pan Teaches Momochrome COB LCD Module

Dr Pan: Welcome to DISPLAY Museum. I am Dr Pan, the curator of Museum.

Greg: Hello, Dr Pan. I am Greg. I came here to learn about COB LCD Module. 

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.

Greg: Thank you, Dr Pan. Now I got it.

Dr Pan:  Welcome to contact us if you have any questions.

New Custom LCD Display Design Development

01 Communication

To start, you have to elaborate on your specific demands. It is best if you can offer your drawings. From our experience, many of our customers only have a concept in their mind and they ask for a quote or samples directly. This is not how it works. Sometimes a video conference or a face-face conference is necessary before we can fully understand your requirements. It usually involves a lot of questions, such as: 1. What is the application of the products ? 2. What is the timeline you’re working from? 3. What problem do we expect us to solve for you?

02 Design

After the first step, we both have some basic understandings . We pass some projects which are not suitable for us. And we can move on the next step: design. To better service our customers and save both of us some time, we will ask you to fill in some of our online forms. Online form custom LCD module. This is the basic information we have to acquire. If you are not certain about some parameters of custom LCD module, we will make the most reasonable design for you from engineering prospect.

03 Quote

Once the preliminary drawings are approved, we offer an official quotation which includes the unit prices, the tooling fees and the other details. Submit the payment if you are happy with the prices. If you can’t accept the prices, we can go back to step two. we can make it cheaper by simplifying the design. After we receive the payment, we will start to make the official drawings. It usually takes 1 to 3 days.

04 Prototypes

At this stage, we build samples based on tooling orders to justify proof of the concept. We can’t start the prototype process unless you sign on the official drawings. It usually takes 7 to 25 days to finish the samples base on the difficulties.

05 Validation

You as the customer validate the efficacy of the custom design before we agree to move into the larger production. It is normal to make several times of prototypes. One time tooling fee and no extra cost until you are satisfied.
