Then he looked at Yang Xiaotao, "Last time you said that transistors can only be regarded as transitional, and integrated circuits are the mainstream of development."

"I feel the same way about that."

"The third underground floor is our research place. We are going to study integrated circuits. Your calculator also uses integrated circuits, right?"

"Yes, but the needs of the calculator are simpler and don't need to be too complicated."

"I know, simple addition, subtraction, multiplication and division, right?"

Yang Xiaotao nodded and then asked about the development of integrated circuits.

Han Sanfeng thought for a moment and thought that Yang Xiaotao was also the person in charge of the project. There were some things he had to know sooner or later.

"We are studying integrated circuits. Although the progress is not fast, simple circuits can still be made."

"What about the display?"

"You are talking about the expression device."

"Yes, can you make it? It's best if it's a liquid crystal one."

"liquid crystal?"

Han Sanfeng smiled bitterly, "Of course we know that liquid crystal is the best, but we have made many requests to the local government, but no one has been able to develop liquid crystal."

"Then how are you going to make the display device?"

"We haven't thought about it yet, but we can't settle this matter."

Han Sanfeng said helplessly, and then the topic shifted to calculators, "The calculator you are talking about should be a simple small calculation device."

Yang Xiaotao nodded, "Yes, it doesn't require too many functions, just addition, subtraction, multiplication and division. There is no need to store it, so a simple circuit board will do."

"Yeah! It'll be much easier that way."

When Han Sanfeng heard what Yang Xiaotao said, she suddenly felt that this calculator was quite interesting and became interested in it.

Of course, this seems simpler than a computer, but it's also relative.

It's not easy to do it.

At least I won't have to think about it in the near future.

As the two of them walked, Yang Xiaotao asked about various situations. Some of his things only existed in his memory, and his specific knowledge was definitely not as good as Han Sanfeng's.

But when you discuss it with professionals, the effect is different.

As long as you raise your doubts, the other party will always be able to think of a solution, and even if it is inappropriate, they can provide reference suggestions.

"Uncle Han, you said the calculator doesn't have an LCD screen. What's the best thing to use instead?"

"This is simple. You can use a TV screen. Anyway, it uses a circuit board. You might be able to do it if you try it."

After hearing this, Yang Xiaotao thought of the TV set at home.

I also think of some things from my past life.

Every time in the middle of the night or early in the morning, I would see a black and white test image, both round and square, with a timer underneath. At that time, every time I opened it, I hoped that the time would go faster and the screen would come out sooner.

The screen projection of this kind of TV is actually controlled by a circuit board.

There are various components on the circuit board, such as transistors and capacitors. They are welded together one by one, and after being powered on, a circuit board is formed.

Then through unique manipulation methods, the image can be expressed on the screen.

It’s just that the welding technology at that time was very rough, and parts would inevitably become loose.

Yang Xiaotao remembers that when the TV at home was playing, the screen would often appear blurred. At that time, the old man would go to the TV and pat the back cover twice, and it would basically be repaired.

At that time, this method of photographing the back cover of a TV set in various ways became a must-have skill for almost everyone.

All this shows that this path is feasible.

"Then let's give it a try first."

"By the way, what do you think about the processing device?"

"This is not difficult. What you want is convenience and no need for storage, so this is different from the two-digit system of computers. You can completely use the ten-digit system, which is also convenient for input and display..."

Yang Xiaotao became more and more excited as he listened, and as Han Sanfeng explained, he felt that the direction of his research was becoming clearer and clearer.

"Uncle Han, why don't you take the lead in this job?"

Han Sanfeng was talking about his opinions when he suddenly heard Yang Xiaotao say this and was stunned.

Seeing Yang Xiaotao's serious look again, he waved his hand quickly, "No, it's not that I won't help you, it's just that I have a lot of things to do and I don't have the energy."

"It doesn't take too much energy. In this way, it's still here for you. Come take a look when you have time, and give me some advice."

"Uncle Han, just think of it as a favor."

"this..."

Han Sanfeng was a little hesitant, not sure whether he should agree or not.

In fact, after learning the whole story from Mr. Wang, he felt a little uncomfortable.

Although it sounds nice, both parties are collaborating on research.

But when it comes to doing it, they are too busy here, so how can they have the time and energy to work on this calculator?

I don't know if this is meant to deceive people.
