What does full key conflict free mean?

The so-called rollover keyboard means that multiple keys are pressed on the keyboard at the same time, and the computer can recognize it. The 104 keys of the keyboard are pressed at the same time, and the computer can recognize them. 、

The signal of the keys on the membrane keyboard is not that each key has a wire to transmit the signal, but that several keys (say 7 keys) share a signal line. At this time, if you press some of these 7 keys at the same time, there will be a key conflict. Some key collision system will alarm, and some will output one of these keys.

Some of the so-called xx game-specific keyboards on the market are better solved to the problem of key conflicts of the keys commonly used in this game. Key conflicts are inevitable (I really want to avoid them completely, the keyboard cable should be turned into a hard disk data cable) Generally speaking, the 3-4 keys of the ordinary keyboard do not conflict, and some high-end points can do 7 keys without conflict.

Mechanical keyboards are all coded keyboards, and each pair of signal lines corresponds to a key, so that no matter how many keys are pressed together, the computer will correctly identify each key, and there will naturally be no key conflicts.

This means that even if all the keys on the keyboard are pressed, the computer will be able to recognize them.

About keyboard conflicts:

Generally, inferior keyboards can only achieve 2-3 keys at the same time without conflict, which can cope with the shortcuts used in daily computer operations, such as: Ctrl+C copy, Ctrl+V paste, etc. Everyday use of this type of keyboard doesn't have much effect, but it's not enough for gaming.

In the case of "PlayerUnknown's Battlegrounds", when running left or right front in the game, the general player will choose to lock the perspective to view the surrounding vision, at this time, the following keys need to be pressed at the same time: up button, left or right button, shift key (run), alt key (lock view), at least four keys need to be at the same time not conflicting, so ordinary keyboards are obviously unusable.

Due to its special structural setting, the mechanical keyboard can meet the needs of at least six keys at the same time without conflict, and the full key without conflict mentioned in the problem means that even if all the keys on the keyboard are pressed, it will not cause conflict.

Advantages and disadvantages of mechanical keyboards:

First, the advantages of mechanical keyboard:

The key switch of the mechanical keyboard adopts a completely different operation mode from the membrane keyboard, and its mechanical structure brings its unique feel to the keys, which is what makes many geek players obsessed. The mechanical keyboard switch body has a long life, and the feel will hardly change during use, and it can also achieve multi-key conflict-free or even full-key conflict-free.

Second, the disadvantages of mechanical keyboard:

The only drawback of a mechanical keyboard is that it is "expensive".

This is a propaganda countermeasure for the membrane keyboard commonly used by the public, because of the circuit structure.

Older membrane keyboards will have key conflicts when pressing multiple keys together, such as if you are playing CS, pressing the "W key", "D key", "Shift key" is squatting down on the cat's waist to touch the fish, then you want to press the "R key" to change the magazine, but find that the "R key" has no effect when pressed, and the magazine can't be changed. . .

Therefore, many game keyboards now will take "multi-key conflict-free" as a promotional selling point, and in fact, most of the general membrane keyboards can also do 3 5 keys conflict-free.

The mechanical keyboard does not have the problem of key conflict from the fundamental structural design, and it is purely publicity.

Because of the problem of the keyboard design principle, the keys on the keyboard cannot be pressed at the same time, this is not to say that the hand is not big enough, but that there may be a situation where you press 1 key, and then press 2 keys and there is no response, this is the keyboard key conflict. Conflict-free means that your colleague can operate normally by pressing multiple or even all of the keys, but. Similarly, because of the principle problem, this so-called full keyboard conflict-free is actually conditional, such as the need to be under the PS2 interface and the like.

The short answer is that all the keys of the entire keyboard can be reflected at the same time when you press them at the same time, and there will be no situation where the keys are not recognized.

Normally, the full key rollover is a gimmick, in fact, if you are playing a game, you are afraid of key conflicts, then it is generally a few large keys that do not conflict, you can operate the keyboard, it is rare to press down more than ten or twenty keys at the same time, so most of the full key punches are just used for propaganda to highlight a professional slogan.

Mechanical keyboard and rollover keyboard are two concepts, mechanical keyboard mainly says that its key triggering is achieved by mechanical switches. The rollover keyboard is mainly related to the control logic inside the keyboard. So whether a keyboard is rollover or not has nothing to do with whether it is mechanical or not.

Membrane keyboards have the same rollover design (of course, ** is not cheap). The reason why most of the rollover keyboards are mechanical keyboards is because the cost of the rollover keyboard is relatively high, and the life of the membrane keyboard is low. The life of mechanical keyboards is much longer than that of membrane keyboards, although punchless machinery is more expensive than punchless membranes, but the gap between the two is not too big, and the life of mechanical keyboards is ten times that of membranes, which is much more cost-effective.

Generally speaking, the upper limit of the response of a membrane keyboard is 6-8 keys when pressed at the same time, and no matter how much it does not respond. Mechanical keyboards do not have this upper limit, you can press more at the same time and it is effective, and it is still meaningful when playing games and fighting or high apm operations, so it is highly sought after by players. But to be honest, it doesn't make a difference in everyday applications.

The simplest way to understand is that pressing multiple keys at the same time will not conflict.

Mechanical keyboards are all used with similar shafts, but I personally think that the use of mechanical keyboards is not only for the better feel, but also to consider the life of the mechanical keyboard? Quality? Maintenance?

Responsiveness, etc.? Mechanical keyboards are all about making them faster. So why not just use the optical axis mechanical keyboard, add some money and directly start the optical axis mechanical keyboard (just like the meaning of fuel vehicles upgrading environmentally friendly electricity price cars).

What are the differences between traditional mechanical keyboard switches, optical switches, and prism switches on the market? Are there similarities?

1. Traditional mechanical shaft: fixed and welded (inconvenient maintenance) and plugging and unplugging shaft body (with copper feet are easy to corrode and the base is in contact with each other to cause defects), short life, not dustproof and waterproof, easy to appear dumb shaft and card shaft, slow input response of about 30ms, easy to vibrate and deform, resulting in abnormal work.

2. Optical axis on the market: the use of physical rough first block or first open knife to isolate light, large noise, stray light leads to slow response, forming a certain tolerance, high deformation of the vibrated circuit board or metal panel, and unstable light source; The supporting tube is coarse and floating, which is easy to collide and cause light loss and poor aging.

3. FLARETECH prism shaft principle: the coupling optical patent that truly adopts infrared control optical path, non-physical shock conduction, each LED passes the stray light through the prism lens, and the light forms a stable and orderly scientific distribution of strong and weak light, and the light with tolerance is refracted asynchronously to the PT receiving tube, and then realizes uniform emission and reception; Long life, less signal noise, the fastest transmission of the actual switch can be reached.

Advantages of FLARETECH prism shaft: anti-shake, zero cache, fast input, low latency, synchronization, no double click, good feel, long life, optical focusing, plugging and unplugging shaft, easy maintenance, stable quality, waterproof and dustproof... At the same time, the biggest difference between the prism optical axis and the commercial optical axis is through the principle of refraction, while the commercial optical axis works by the principle of cutting off the light source, so there is a big difference in input speed and delay jitter.

Similarities: the same mechanical keyboard, the same stroke, the same keycaps.

Ordinary keyboards, because of internal circuit and design and construction problems, generally hold down 3-5 keys, or hold down 2-3 keys for something, the key will be locked, the so-called lock key is no response when pressed, and long press the motherboard will have a prompt sound. The full key of the mechanical keyboard is that if you press all the keys down, you can identify it, and there is no key lock problem.

If you usually work, the ordinary keyboard can meet the needs, some of the current non-mechanical key game keyboards, through special design, to avoid the lock key conflict in the key area, up to 6-8 keys can be achieved without rush, can meet the special needs of the game, of course, it will be a lot more expensive, mechanical keyboard is actually not full key rollover (but it is also 6-8 keys without conflict, to meet the special needs of the game).

Full keyboard conflict-free means that all keys are pressed at the same time, and the computer can recognize them all.

Due to the different structures under the keycaps, the mechanical keyboard can achieve at least 6 keys without conflict, and a good mechanical keyboard can even achieve full key without conflict (the keyboard mentioned in the question is this one), while the ordinary membrane keyboard can only do 2 or 3 keys without conflict, which is most obvious when playing games, for example, when playing CS on an ordinary keyboard, if you hold down WD to run to the right front, you can't press 2 at the same time to cut the pistol, but the mechanical keyboard can do this, even more complex combination keys, The computer can also recognize it without errors.

Mechanical Keyboard Benefits:

1. The mechanical keyboard can reduce typos.

Depending on the type of switch (axis), different haptic feedback can be obtained, and when a key is pressed, the real feel helps to determine what is being entered. At the same time, it is supplemented by a crisp input sound, which can achieve more accurate input results when typing blindly, which is not possible with a quiet membrane keyboard.

2. The mechanical keyboard is more durable.

Another great benefit of mechanical keyboards is their durability, especially for heavy users. Depending on the model purchased, the keys can achieve a typing life of tens of millions of times, which is unmatched by fragile membrane keyboards. The lifespan of membrane keyboards is very short compared to mechanical keyboards.

In addition, because it is mechanical, it can be equipped by itself even if the keys are lost, and it is relatively easy to clean and maintain.

3. The mechanical keyboard feels better.

Every time a mechanical keyboard clicks a key, it will get a deterministic tactile and acoustic feedback, and over time, this tactile and auditory cooperation will bring a good input feeling and effectively reduce typos.
