May I ask how the screen touch of the 8220 feels compared to the M8 Will it be inaccurate?

The M8 G1 5800 iPhone has been used to tell you about it. On the feel, the iPhone>M8>G1>5800 M8 feels very good. It's much easier to use than the A system. aThe system feels stiff to the touch. See more answers

After playing M8 for a few minutes, I completely agree with you, it seems that these two machines are the pride of domestic products!! But the cost performance is really about the same, after all, 8220 is cheaper for hundreds of dollars, and the quality of M8 should not be as good as that of 8220, but now that I am just starting to use it, it will take time to verify it.

I think 8200 is still good. The key depends on how you operate. After a while of using it to cooperate with the machine, it will be easy to use.

I didn't find the 8220 screen edges insensitive. It feels good to use. I haven't used the M8 before, though, so I can't compare.

I've considered M8 before, but I haven't used it, and people on the Internet say it's too evil, and there are many problems, and I can't verify it, so I don't want to experience it myself. Google's system is still in its infancy, and it's still a long way to go, but I feel like Google's things are fighting with Apple, and all of them will be felt first. In fact, it's still a good machine.,I didn't use BlackBerry before I thought the full keyboard was typing.,Wait for it.,I think typing is fast.。

It's all experienced, brushed and played, hehe.

A capacitive touch screen can be simply seen as a screen composed of four layers of composite screens: the outermost layer is the protective layer of glass, followed by the conductive layer, the third layer is a non-conductive glass screen, and the innermost fourth layer is also a conductive layer. The innermost conductive layer is the shielding layer, which plays the role of shielding the internal electrical signal, the capacitive screen expert No. 183, the middle four digits 2005, and the back is 9375.

The conductive layer in the middle is a key part of the entire touchscreen, with direct leads at the four corners or four edges that are responsible for detecting the position of the touch points.

The capacitive screen responds quickly to 5-15ms, and you can touch and play games with both hands at the same time, with fast response speed and beautiful appearance.

The resistive touch screen is controlled using pressure sensitivity. Its main part is a resistive thin film screen that is very well matched with the surface of the display, which is a multi-layer composite film, which uses a layer of glass or hard plastic plate as the base layer, and the surface is coated with a transparent metal oxide (ITO) conductive layer, which is covered with a layer of hardened outer surface, smooth and anti-scratch plastic layer (its inner surface is also coated with an ITO coating), and between them there are many small (about 1 1000 inches) transparent spacers to separate the two ITO conductive layers of insulation. When the finger touches the screen, the two conductive layers that are usually insulated from each other have a contact at the touch point, because one of the conductive layers is connected to the 5V uniform voltage field in the direction of the y-axis, so that the voltage of the detection layer changes from zero to non-zero, and the controller detects this connection, performs a D conversion, and compares the obtained voltage value with 5V to obtain the Y-axis coordinates of the touch point, and the X-axis coordinates are obtained in the same way, which is the most basic principle common to all resistive technology touch screens.

The resistive screen is cheaper than the capacitive screen, the resistive screen is not as fast as the capacitive screen, the resistive screen is a single touch, the capacitive screen supports 10-point touch, and you can see that the capacitive screen has a greater advantage than the resistive screen.

The structure of the capacitive touch screen is mainly to coat a transparent thin film conductor layer on the glass screen, and then add a piece of protective glass outside the conductor layer, and plate narrow electrodes on the four sides of the touch screen to form a low-voltage alternating electric field in the conductor. When touching the screen, due to the existence of the electric field of the human body, a coupling capacitance will be formed between the finger and the conductor layer, and the current emitted by the four electrodes will flow to the contact, and the current strength is proportional to the distance from the finger to the electrode, and the controller behind the touch screen will calculate the proportion and strength of the current to accurately calculate the position of the touch point.

Compared with resistive touch screens that were common on the market at the time, capacitive touch screens had obvious advantages. First of all, a capacitive touch screen only needs touch and does not require pressure to generate a signal, while a resistive touch screen is activated by pressure. Secondly, capacitive touch screens have a long average lifespan.

Again, in the resistive touch screen, the upper film needs to be thin enough to be elastic, so that it can bend downward to contact the film below, so it is easy to be damaged, while the capacitive touch screen cover can be relatively thick, and there is glass protection, good scratch resistance, which can better protect the conductor and inductor. In addition, the capacitive touch screen is more durable, less prone to aging, and resistant to high temperatures. Moreover, the double glass design of the capacitive touch screen can more effectively prevent the impact of external environmental factors on the touch screen, even if the screen is stained with dirt, dust or oil stains, the capacitive touch screen can still accurately calculate the touch position.

More importantly, the touch screen at this time has developed from the early analog touch screen to the digital touch screen, which can realize multi-touch.

When testing the touch screen, it is necessary to choose a high-current shrapnel microneedle module, and the appropriate test module can play a good connection function, and can play an excellent role in the on-current and transmission signal!

The difference for the user is that the capacitance only works by the hand, and it is extremely sensitive! The feeling of resistance can work for anything, but it is not sensitive, and the keys need to be forced...! After using N8 and N97, you can clearly feel the difference between capacitance and resistance!

Capacitive screen is more NB recommend Meizu M8

Resistance touch is to read out the parameters by touching the change of the resistance value.

Capacitive touch is the change in the capacitance value that is coupled by the charge, and the parameters are read out.

This is a touch screen failure, most likely is a large area of short circuit in the internal channel of the touch screen, resulting in the touch display area in a local position, because the short circuit can be understood as touching in the upper left corner, but this part of the channel is short-circuited with the channel in the lower corner, and it will be judged to be in the lower right corner when positioning. (Why is this in the lower right corner related to the judgment algorithm and the order of scanning), because the local abnormal concentration of the data will have problems with the calculation, so it is normal to have a delay.

Generally, it can only be handled by replacing the touch screen.

From the ** point of view, the capacitive screen is more expensive.

In terms of accuracy, capacitive screens are more accurate.

Operationally speaking, the capacitive screen uses the human body to induce capacitive coupling to work, while the resistive screen uses external forces, such as fingers or special stylus, and the latter has almost no limitations.

In terms of lifespan, capacitive screens are longer.

In terms of development, the capacitive screen is the future development trend, and the resistive screen will be gradually eliminated In terms of reaction, the capacitive screen has a fast response speed.

By the way, resistive screens can also achieve multi-touch, which is not a patent for capacitive screens

Capacitive screen: touching with the tip of the pen does not work, touch with your fingers (it is actually induction, not the pressure of the tip).

Resistance screen: On the contrary, it should be touched with the tip of the pen, and finger sensing will not work. Mainly by the pressure of the tip.

The capacitive screen supports multiple contacts. And it can be recognized by just touching it with your fingers, without pressing hard. The screen is more swivel.

Can be made thinner. The disadvantage is that it must be directly or indirectly touched with **. **Sweat on it will not be recognized.

Resistive screens do not support multiple contacts. The touch type must be forced. It's a bit low-cost.

Accurate identification, support a wide range of devices. With the development of technology, resistive screens will gradually be replaced by capacitive screens...

Resistive one-touch control, capacitive multi-touch control.

Basically agree with caowenmingren's point of view,But M8 beta version and SE version I have used,M8 should use axis staggered capacitive touch technology,Strictly speakingM8That can't be regarded as multi-touch technology at all,There is a point that is a pseudo point,I can only reluctantly say that it achieves 2 points of touch。 There is no resistive screen or anything in it. It is easy to completely burn the touch screen circuit with the flint discharge method to neutralize the static electricity, and it is also a symptom but not a cure.

It is best to return to the factory for repair, this fault is a design defect and the warranty is also free of charge.

The working principle of this M8 screen is related (the shortcomings of the early resistive screen), the same is true of the early Apple 2, your way to deal with it depends on luck, some people are lucky that there are no problems for a year. However, I suggest that you exchange the M8 for the M9 or MX, which can be discounted by 700 yuan.

Temporary. It's the same with my previous M8.,Electricity is fine.。。 Later it got worse and worse. After returning to the factory, it was no problem to change it to now... But now it's time to change to MX.

zhsllove makes sense, the resistive screen is pressure-sensitive, and you can click the mouse with a wooden stick; The capacitive screen is induced by an electric field, and there must be a conductive east, so people wearing gloves can only use a resistive screen. But the brightness of the capacitive screen is indeed higher. But writing with your fingers isn't very cool.

In addition to being able to touch more, I don't feel that the capacitive screen has much advantage.

See if you can point with your nails, what you can point with your nails is a resistive screen, what you can't point with your nails is a capacitive screen, of course, if you can point your fingers, it's a capacitive screen, and if you can't point anything, it's just a display screen.

The capacitive screen can only react with the meat dot on the finger, and the resistive screen can be lit with anything.

The point screen is more sensitive than the resistive screen, and the capacitive screen does not respond with a pen.

Haha......This problem,First of all, I want you to determine the nature.,If it's the same as mine.,It's part of the screen that fails.,Can't operate,I can recommend a way to you.。

Just go to the street and buy a lighter, ask for the kind that can be disassembled, and take out the "electricity" part inside (sorry, I don't know the specific scientific name......I'm going to use it in a moment.

The mobile phone can be turned on and off, pinch the upper left corner of the M8 screen with the thumb and index finger of the left hand, and the thumb should cover the screen and the frame, and then, the right hand uses the "power" Dongdong, shock the lower right corner of the screen, two or three times in a row, it should be OK.

1.I think it's about two weeks.

2.It is possible to repair the screen, or it may be replaced directly (there is a precedent), and it is free of charge during the warranty period.

3.Send it to Meizu headquarters at the address on the official website.

The screen failure is not a problem, there are two reasons for the choice, first, there is a problem with the touch screen itself, change the touch screen, and it can be solved in a few minutes. 2. If the touch screen circuit fails, if it has been dropped or flooded before, there is a high possibility of problems in the circuit, such as the virtual welding of the cable or the wire base.

During the warranty period, go to the designated maintenance point, generally will not repair the screen directly, there are accessories and wait for a while, no accessories to ask the maintenance personnel.

Meizu warranty. Generally, it is necessary to return to the factory. Maybe there are still warranty points in big cities. If it is within the warranty period. Your screen is not broken. It should not be expensive to repair. It's just that the touch is out of order, and generally you buy it there and fix it there.

en inductor changed, estimated for a week, be careful not to be stolen by someone to change the internal materials. Specially repaired. Otherwise it's a lot of trouble.

It's so disappointing for me, I'm just like you, the screen part is out of order. I called their service department's **0756-6120888, I couldn't get through in the morning, I'm very angry now, I'm so disappointed, it's really disappointing.

Today I followed the soil method on the Internet, the electric shock method and the discharge on the ground, and the effect was much better, but the lower left corner is still a little ineffective, I don't know if anyone can teach me a better way.

There is a high possibility of changing the screen if there is a quick one.

The workaround is as follows;

Go to a nearby mobile phone store for testing and repair, and go to after-sales inspection and maintenance [after-sales is more expensive].

There are three definitions of repair, which are replacement parts, pure repair parts, modification according to function, maintenance and restoration, maintenance, maintenance, and repair.

Go to the seller and get the invoice to repair it as long as it is not man-made damage.

There are three packs of quality.

Go to ** that change.

M8 is currently a one-year free replacement for screen failure.

Sent directly back to Meizu's Zhuhai headquarters, because Meizu's screen accessories had a problem, and a large number of machine screens failed in the month.

The problem of screen failure is that it can be replaced for free, the new policy of Meizu boss personally, the machine I bought in June failed, in mid-August, I directly spent 20 yuan to send it to SF Express, just got a free new machine, Meizu bears the postage of the return mail, remember to attach the warranty card, and a small note explaining what is wrong with the mobile phone, you ask for a free change, about 2 weeks to get a new machine.

Go to change it, M8, there is a problem with the screen, this was discovered very early, it is said that there is a problem with the screen itself, and it can be replaced
