In today's mobile phone market, mobile phones like Nokia no longer exist. Instead, large screen mobile phones such as Samsung, apple and HTC are easy to break. Can be called the arcade Samsung S4 mobile phone can be said to love and hate, love its super large screen, hate it vulnerable. What's more, after some students' small 4-screen is broken, only the external screen is damaged, and the internal LCD and touch screen are intact. Therefore, it becomes a problem whether to change the external screen or the whole screen. Therefore, today we will talk about the right and wrong of Samsung S4 mobile phone's external screen, and help everyone who has broken the screen to make a choice.
First, let's understand the screen structure of Xiao Si
Samsung s4led screen does not have backlight, and the whole screen adopts full fit technology. Its structure is divided into external screen, mirror, touch and LCD. There are three floors. The outer screen mirror plays a role of toughening protection. Touch is touch function, LCD is to play the role of display load.
Kangning mirror steel machine is made by SamSung company. The screen mirror is bonded on the inner screen by photochemical solid glue.
Screen separation is the key
Because the mirror surface of the outer screen is attached to the inner screen by photochemical solid glue, it must be very difficult to separate manually. The inner screen itself is also fragile glass. Without professional equipment and tools, the inner screen will be damaged. Therefore, the general maintenance direction or after-sales can only be changed together with the whole screen, and only Samsung processing factory can assemble and make lamination. After sales does not have the function of replacing the external screen separately.
Therefore, if your Samsung S4 screen is broken, Xiaobian's suggestion is not to replace the external screen or the whole screen, but to change the mobile phone directly. After all, the price of Samsung S4 is falling too fast. Judging from the market situation around may 2014, the second-hand price of S4 is about 1000.
