Tutorial: Dr Pan Teaches COG LCD Module

Script

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 COG LCD Module.

Dr Pan: Hello, Greg. COG is the abbreviation for chip on glass. It is a technology, which IC is bonded directly onto ITO glass. COG technology is usually used in small size dot matrix monochrome LCD module and TFT LCD module.
COG LCD module is so popular because of following reasons.
NO.1, it can greatly reduce the size of the LCD module because it doesn’t have PCB and it can be as thin as 2.0mm (maybe thinner). The thinner the more expensive.
NO.2, it is simple structure and easy for mass production of consumer electronic products, such as: mobile phone, PDA and portable device, etc.
NO.3, it is cost effective over COB LCD and can totally replace COB LCD in function, especially in graphic LCD modules, because it reduces the number of IC.
NO.4, for some dot matrix LCD modules, it is not possible to apply COB LCD technology because it is too crowded to place so many points on the view area. COG LCD is an economical and feasible solution because the pitch is smaller .
NO.5, it is replaceable. It is so easy to replace COG LCD module with FPC connection if it is malfunctioned.

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

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

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.
