Some time ago, the brain pumped, I have to think of myself to change the ipad2 into the car control, but I usually stop the wild car, I am very embarrassed, and every day I have to take off the ipad to hide it, the Celestial glass Party, you guys know. In those days, it was estimated that there were more squats, and the hand did not work hard.
Because during the Spring Festival, plans to drive by car, no ipad no music, 1 day driving hours, no music how to do, but fortunately when the stalls, with the next door of the film's sister learned a hand, and quickly posted a film, Spring Festival The period will be used in the past. 
How is it?
After the Chinese New Year holiday, network operators and express delivery have gradually returned shipments, and I quickly set a touch screen to change.
Ipad2 touch screen _ Taobao search Taobao search is the most intelligent product search engine, through the operation of big data, accurate understanding of goods and users, providing accurate personalized search experience. Direct links to s.taobao.com Ipad2's touch screen and internal screen are separate, after the external screen is broken, you can only change the touch screen alone, of course, you go to the official maintenance point, it is certainly for the assembly together.
Received a touch screen, began to wait to see disassemble video, ready to change their own screen.
Bold and hearty, break all the outer screens, peel them off, and look like the picture above.
Continue to open the 4 screws inside the screen, open the inner screen to see the inside of the ipad.
Here is the line of the touch screen. It was originally to open the two screws below, and then press the cable, but I accidentally, one of the screws collapsed, only the blade to open the line, so a set of Good tools are necessary.
Installed external screen test
After the test, tear off the film and finally fit it.
How about, not bad, but with eggs, an excessive force.
TMD broken again. Due to the fact that it had fallen a few times and the edges had been deformed, the new external screen could not fully fit. I had a hard time and the background created.
But fortunately, you don't see it with your sleeve.
After the screen change, the use of sure did not have the original cool, the first internal and external screen gap is large, when the screen for the fingerprint left in the screen, but also when the time is hidden. Because of the deformation around the screen, the screen can not be very fit, sometimes with the use of the upturned, so a fit of the cover is a must, and change the screen to bring a good thing is that the home button and spirit! !
Finally, I wish everyone's screen is not bad
The category introduction of Low Frequency UPS Power Supply can be explained from its definition, characteristics, applications and development trends. The following is a detailed introduction to the low-frequency UPS power supply:
I. Definition
Low-frequency UPS power supply, as the name suggests, refers to the use of low-frequency switching power supply technology UPS system. This UPS has a lower switching frequency than a high-frequency UPS during the conversion process. While the specific "low frequency" range may vary by product and standard, in general, low frequency UPS switch at a much lower frequency than high frequency UPS.
Ii. Characteristics
High reliability:
Low-frequency UPS usually use more mature technologies and components, with high reliability and stability. The design is often more focused on system redundancy and backup to ensure continuous power supply at critical times.
Strong anti-interference ability:
Because the switching frequency of low-frequency UPS is low, its electromagnetic interference to the outside world is also relatively low. This makes low-frequency UPS more advantageous in some occasions with higher requirements for electromagnetic environments.
Large size and weight:
Compared with high-frequency UPS, the components and circuits of low-frequency UPS may be larger and more complex, so its overall volume and weight are also larger. This limits the application of low-frequency UPS in space-limited environments to a certain extent.
The conversion efficiency is relatively low:
Low-frequency UPS may generate more energy loss during the conversion process, so its conversion efficiency is relatively low. However, with the advancement of technology, some new low-frequency UPS are also trying to improve the conversion efficiency.
