Chapter 1972: touch screen

A whole screen! In front of the entire cockpit, there is a whole screen! This has surpassed the level of F22 and evolved directly to F35.
Although the military science and technology is developing rapidly, the current situation still scares Qin Guan. This step is too big, will it get involved?
Now the domestic cockpit, one level and three times has become the mainstream layout method. On this basis, it seems normal to use a larger screen and turn three pieces into one. However, the current test aircraft, Qin Guan was still a little worried about playing this full screen.
But Chen Rui was very satisfied.
"We should have done this a long time ago. You can display whatever you want to display, and go to the irrelevant data. Especially on the right side, I can call it up and display the plane's mounting. Come, power on, and show it to President Qin."
Before the first flight of the fighter aircraft, there are a series of taxi tests, low speed, medium speed, high speed, especially the front wheels have to be pried up to verify that the aerodynamic layout of the aircraft is okay. This is the end. During this process, the display screen It must all light up.
Chen Rui is most satisfied with this large screen. It is quite intuitive. If it is taken out, it will definitely be the envy of the whole world. This is the latest technology of Han Guo. On the LCD screen, there is no time for foreign countries to catch up. A new generation of products has been developed in China.
Now that the fighter is powered on and the screen lights up, you can see that this LCD screen emits green light most of the time. This is the best color for the eyes. The bright green lines form a The pattern on the right screen is the shape of a fighter plane. Inside, a Meimei missile can be displayed!
It's very intuitive and clear. Chen Rui likes this feeling the most.
Now there is nothing there, because the pylon in the belly of the plane is empty and there is nothing, but when there are missiles in it and the interface is in contact, it can be displayed.
He poked his finger on the screen, and then a new simple window popped up on the screen. It is all gray now, because the missile is not equipped, but you can see the instructions inside. Just simply press it. Preparations for launch can be completed!
"Touch screen?" Qin Guan was surprised. In this regard, he didn't know that his own technology developed so rapidly that the touch screen was actually superimposed on the outside of the LCD screen? In later generations, everyone likes to slide their fingers on the screen, but it looks like the first touch screen mobile phone, which only appeared in the 1990s, and I have not exchanged this technology.
"Yes, touch screen, this kind of technology appeared in the 1960s, but in our case, it is the latest achievement of technicians." Lu Lao said.
what? Has it been in the sixties? Qin Guan is very strange, it seems that he is not omnipotent, it is impossible to know all the technical details.
In 1965, Eagle Country Radar Researcher Johnson published a short paper "Touch Panel: A New Computer Input Device" in the "Electronics-Letters" magazine. His ideas made the most crazy The author of science fiction is impossible to think of.
This is an idea of ​​a capacitive touch screen: the main body of the screen is a composite glass screen, the inner surface is coated with a layer of metal oxide called ITO, and there are four electrodes on the four corners. It's as simple as that. Then, when the finger touches the glass screen, due to the human body’s own electric field, the finger and the metal layer of the glass inner layer will form a capacitor, thereby "sucking away" a small amount of current at that location. .
Although the touch screen technology was successfully commercialized, the resistive touch screen was the first to be used, but when it was first born, it was really a capacitive touch screen. Through the principle of capacitance, the current
leaked
out, and in theory, it flows through different The part of the electrode is proportional to the distance from the finger tip to the electrode. Through the precise calculation of the controller, the position of the finger can be accurately obtained.
At that time, no one really thought that this thing would be realized. However, Johnson made this kind of thing two years later. However, his capacitive screen was not widely used, and the resistive screen was developed by accident. However, compared with the two, the metal coating of ITO is used. The difference is that this layer of metal is coated on a thin film that is easy to press. When touched, the metal coating will touch the conductive back The board brings the passage of electric current.
In this way, the position record can be calculated by laying out the coordinate axes arranged vertically and horizontally on the conductive plate.
Although it cannot be displayed, it is like a whiteboard, but it is very efficient and quickly used in a large number of fields.
If the touch screen is made into a transparent glass shape, and a real display screen is placed at the back, after the two are aligned, you can directly click on the graphics displayed at the back!
This invention was made by Hanxin Technology. The touch screen mobile phone made according to this principle has been studied by Jobs. It is known as the greatest invention, and they have also applied for a patent. .
Now, when used in the cockpit of one's own fighter, it has become a means of interaction between the pilot and the cockpit electronic equipment. Compared with the mouse, it is definitely a lot more direct and more efficient. After Chen Rui came, his favorite is Tap this screen in the cockpit with your hands wearing pilot gloves.
It is precisely because of these powerful electronic technologies that the current modified stealth machine is single-seater, although there are also two-seater models, it has evolved into a model that mainly attacks ground to sea, air combat, A single seat is enough.
Qin watched the equipment in the cockpit for a long time without speech, joy, or too much shock. For him, there were even some worries. After all, it was only in the 1980s and the development of electronic technology was limited. Moore's Law It is still the most correct law. Is their progress too great? Will there be any problems?
"This fighter is still a prototype. Because there are too many new technologies, we expect that the test flight will be long, possibly more than five years. During this period, a large number of new technologies will mature, such as With new airborne radars, new engines, etc., when the final shape is finalized, this fighter will have a big improvement." said Lu Lao.
Don’t look at Lu Lao’s age, but among the older generation of fighter development personnel, Lu Lao was the only one who had stayed abroad and drank foreign ink, and was also the most daring to use new technology with a big sword. , Who else would dare to change the air intake of the F-6's nose to both sides? Just look at Jianba's conservativeness.
Qin nodded in view: "You must be cautious when you test the flight."
