Tutorial: Dr Pan Teaches Teaches TN LCD Screen

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 TN LCD Screen. 

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.

 When it is a positive and reflective display, it can display without LED backlight; when it is a positive and transmissive/ transflective display, it can’t display without LED backlight, the background color is grey and the letters are black.

When it is a negative and transmissive/ transflective display, it can’t display without LED backlight, the background color is purple-black, different colors from different view angle, and the color of the letters is the color of LED backlight.

By the way, no matter it is a positive or negative display, the background color is affected by the color of LED backlight on some level. That is why the color of LED backlight is usually white.

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.

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.
