The open beta of "Zhu Xian" on the night of July 1st is definitely a joyful and annoying thing, Weishenme said, because many people were squeezed into the novice village for more than an hour before someone found a directional moving charm, which is not expensive, because the distance of movement is only ten yards, which is five hundred meters in reality.

Because one low-grade spirit stone can buy a hundred of these talismans, many people generously use the three low-grade spirit stones given by the newbie gift package to buy a hundred of these talismans.

After many people were teleported, the flow of people was immediately slowed down.

This also allowed the game to work normally, but a spectacular phenomenon appeared before the eyes of the world, Weishenme said, because a small beast and boar were attacked by a large number of players.

But now many people have begun to curse.,Because the explosion rate of equipment is too low.,Basically, brush a hundred monsters.,It's good to be able to explode one.

Almost the next day, Lin Nan received a news that made Lin Nan excited, this news came from the military base laboratory.

The touch screen handed over by Lin Nan has already achieved new results, and according to the test effect, it is not bad, and it can achieve five-point touch.

And the sensitivity is not bad, and it can respond in minutes.

Touch screen (touchscreen), also known as "touch screen", "touch panel", is a kind of inductive liquid crystal display device that can receive input signals such as contacts, when touching the graphic buttons on the screen, the haptic feedback system on the screen can drive various connection devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create vivid audio and video effects through the liquid crystal display screen. As the latest computer input device, touch screen is currently the simplest, most convenient and natural way of human-computer interaction. It gives multimedia a new look and is a very attractive new multimedia interactive device. It is mainly used in public information inquiry, leadership office, industrial control, military command, video games, song ordering, multimedia teaching, real estate pre-sale, etc.

However, at present, the touch screen is in its infancy, and few people will use the touch screen, especially in the civilian stage. In these special fields of the military, there may be people who use touch screens, which are not as widely used as in later generations, perhaps this jishu is some untouchable high-tech in the eyes of the world, a thing that only exists in movies.

There are three major characteristics of the touch screen, and each of them is also one of the problems of the touch screen.

The first feature is transparency, which directly affects the visual effect of the touch screen. It's not enough to summarize its visual effect in terms of transparency, it should include at least four characteristics: transparency, color distortion, reflectivity, and clarity, and it can be divided. For example, the degree of reflection includes the degree of mirror reflection and the degree of diffraction reflection. Although these four can't completely summarize the transparency feature, for the average user, it is enough!

The second feature is that the touch screen is an absolute coordinate system, and you can click directly on it if you want to choose, and the essential difference between the relative positioning system such as the mouse is the intuitiveness of being in place at one time.

But the characteristic of the absolute coordinate system is that each positioning coordinate has no relationship with the previous positioning coordinate, the touch screen is physically an independent coordinate positioning system, and the data of each touch is converted to the coordinates on the screen through the calibration data, so that the touch screen is required to have this set of coordinates no matter what the situation. The output data at the same point is stable, if it is unstable, then the touch screen cannot guarantee the absolute coordinate positioning, and the point is not accurate. That's the biggest fear of touchscreens: drift.

In principle, all touch screens that cannot guarantee the same touch and the same sampling data at the same point will inevitably drift, even in later generations, this kind of thing is common, but basically it only appears on the capacitive capacitive screen.

The third feature of the touch screen is to detect touch and localize, and all kinds of touch screen jishu rely on their own sensors to work. There are even touchscreens that are a set of sensors in their own right. The respective positioning principle and the respective sensors used determine the response speed, reliability, stability and longevity of the touch screen.

The touch screen is not only a capacitive touch screen, but also a vector pressure sensing jishu touch screen, resistance jishu touch vector pressure sensing jishu touch screen, resistance jishu touch screen, capacitive jishu touch screen, infrared jishu touch screen, surface sound wave jishu touch screen.

The arrival of this news indicates that some of the following jihua are about to unfold. Of course, what Lin Nan has to do now is to find a way to mass-produce this touch screen, and the most important thing is that the yield rate must be high, otherwise everything will be in vain.

"It's just that I haven't been to the Mobile Processor Research Institute for a long time, and I don't know if there is any substantive effect there?!" Lin Nan seemed to think of something, a little chattering, and what he didn't notice at all was that he had just been to Li Hai not long ago, and asked the family to optimize the big processor.

"You're going to have someone send me a screen like this now!" Lin Nan thought for a while and felt that he needed to shiyan himself, but Lin Nan didn't want to move anymore, so he lazily gave the person in charge of the touch screen a phone call and asked her to ask someone to send a sample of the finished touch screen to herself.

"Eh, this is the situation of Shenma?" Hearing Lin Nan's thoughts, the person in charge, Cao Jianhua, was not calm, what is the situation, I will send you a piece of the past, who will be responsible if there is any problem during this period? ! I'll send you a fart, do you have the equipment to verify? But after all, the boss's words still have to be listened to.

"Xiaomi, you send the touch screen on the No. 5 platform to the headquarters of Qianlong Company and hand it over to our president, remember to personally hand over the things to our president Lin Nan." Cao Jianhua pondered for a while and said, ready to be delivered in person, and it was delivered by hand, and the product was password protected

An hour later, a black sedan appeared at the door of the Qianlong headquarters, and a man walked into the Qianlong headquarters with a black lockbox in his hand.

First he said something at the front desk, and then someone brought the man over.

"Mr. Lin, hello, I am a scientific and technological staff of the Touch Screen Research Institute, entrusted by my leader, I will send this to you and hand it over to you!" The man walked into Lin Nan's office, looked at Lin Nan expressionlessly, and said solemnly.

"Hmm!" Lin Nan stood up, answered, took the lockbox, and opened the lockbox correctly according to the password given to him by Cao Jianhua, because now that this jishu has just appeared, the finished product must not be lost, otherwise it will be stolen by others, and all efforts will be almost in vain.

Therefore, Cao Jianhua is not cautious.

"Xiexie, you can go back on an errand!" After Lin Nan saw the things inside, he said to the man after monitoring some things that were similar to what Cao Jianhua said.

The man nodded, but did not leave, but removed an agreement that he had brought with him, which needed to be signed by Lin Nan, because it could prove that Lin Nan had indeed received the product, and everything after that had nothing to do with him.

As the saying goes, once something happens, it is not convincing without black and white, so it is necessary to do so

Lin Nan took a look, there was nothing unusual, took out a signature pen, and signed his name on it.

After receiving the signed agreement, the man didn't stay long, left here directly, and went back to report to Cao Jianhua.

After the person left, the touch screen in Lin Nan's researcher's hand lightly clicked a few times and tried the feel, feeling a little jerky, but considering that it was a laboratory product, he didn't say anything.

Turned around and walked into his lounge, and then entered a small room, which was full of some advanced personal experimental equipment, and in this room with an area of only five square meters, there were experimental equipment worth millions.

Do it under the specialized instrument, open the device, and then find some electronic components for soldering.

An hour later, a simple circuit board appeared in Lin Nan's hand, which was the simplest circuit board for testing circuits, and after connecting to the touch screen, the test began. (To be continued......)
