Compared with the previous generation, the Kindle PaperWhite 3's screen has become a new display screen with 300PPI, and its memory has doubled. The system responds faster. However, what is the internal structure of the Kindle PaperWhite 3? Let's unravel the mystery with our disassembly!
Before disassembling the machine, hot air guns, crowbars, tweezers and screwdrivers of different sizes are required. If there is no hot air gun, household hair dryers can be used instead, but the temperature should be controlled properly.
Heat the front of the kindle evenly with an air gun, and it is easy to disassemble after the glue is softened;
Use a pick and other tools to move along the gap of the front panel and slowly pry open a gap;
Slowly remove the whole panel frame;
After removing the frame, we can see the screws on the aluminum magnesium alloy frame fixing the screen;
We can see the four backlights at the bottom of the screen. The backlight function of the entire Kindle is realized only through these four backlights through a specially designed light guide plate;
It is worth noting that a screw is hidden under the black tape at the top of the screen, otherwise the machine cannot be removed smoothly;
A total of 11 screws fixing the middle frame and the back shell can separate the middle frame and the back shell. The reason why the middle frame uses aluminum magnesium alloy is that it can improve the strength of the fuselage and provide more protection in case of accidental fall;
After separation, you can see the motherboard and battery;
After removing the three screws that fix the battery, the battery can be removed;
The battery and the motherboard are connected by electric shock. Since they are fixed by screws, this method is also reasonable;
A buckle is also provided in the middle of the back shell to buckle the aluminum magnesium alloy middle frame;
Then we remove the 4 flat cables on the motherboard;
The flat cable of the display screen also has a plurality of capacitors and resistors;
After the flat cable is removed, there are as many as 7 screws of different sizes on the motherboard;
After removing the flat cable and screws, the main board can be removed, but there is conductive metal tape between the main board and the middle frame;
After prying off the mainboard gently, it can be removed;
The Kindle's charging indicator light is wrapped by a black rubber sleeve. After taking it off, we can see that the LED light does not scatter outward directly, but plays a "soft light" effect through the plastic light guide plate, which is why the Kindle's indicator light looks soft and comfortable.
The whole Kindle PaperWhite 3 has as many as 21 screws of at least 4 sizes, which shows that the structural design is demanding for details.
Well, this is the end of the disassembly. Finally, I present the family photo.
