简介
拆卸显示屏需要割开屏幕四周的胶条。胶条被割开后，就不能用来重新将显示屏密封到位，因此需要重新贴上一组新的胶条。
你所需要的
-
在这个步骤中使用的工具：iMac Intel 21.5" Cardboard Service Wedge$4.99
-
一旦铰链可以自由移动，iMac 将失去平衡，难以操作。在支架上放置一个 iMac 支架 以稳定 iMac。
-
-
-
如果要重复使用现有的显示屏，还必须清除显示屏背面的旧粘胶。
-
用镊子或手指剥离旧的胶条。从底部开始，向设备顶部向上剥离。
-
清除所有旧胶条后，用高浓度异丙醇（90% 或更高）和无绒布仔细擦去胶条残留物。顺着一个方向擦拭，不要来回擦拭。

-
-
将麦克风槽口对准麦克风孔，将胶条对准底部边缘。
-
如果你的 iMac 没有麦克风孔，请对齐胶条的右端，使 L 形弯头位于右侧垂直粘合剂旁边. L 形弯曲不应与右侧垂直胶条重叠。
-
对齐胶条后，小心地将左侧露出的边缘固定在 iMac 上，以确保对齐。

Good Lord, why does Apple have to make it so difficult to upgrade or repair? There comes a point where design aesthetic just isn't worth it. Magnets, like I believe older iMacs use to attach the front glass, would have made it much easier. I'll take the extra bulk any day.
Have you actually done the replacement? It's actually pretty easy. Apple did everything they could to make it as painless as possible: the old adhesive separates without *any* residue, it doesn't rip apart, it doesn't make a mess. Things align like magic.
True, it could be easier. Like with the old color iMac SD. But since I don't take my iMac apart every day, doing this once or maybe twice in my computer's lifetime is a small price to pay for a *really* slim and good looking device.
I had some issues with steps 21, 22 and 23 ... the tabs would rip off. After the third one I used the plastic card to gently create some space for the strip to escape.
Thank you for this fantastic guide, and all of the iFixit guides! Just finished this replacement using the iFixit Adhesive Strips/iMac Opener tool combo--everything worked very well, except that the iMac Opener tool did not particularly like the broken glass area of the display, which bent the plastic of the "pizza cutter" wheel a little.

One bit of helpful advice is to use extreme care when placing the replacement display back into the iMac. Make sure that you do not put the display back in at too great of an angle, or there will be a very noticeable gap at the bottom, between the display glass and the iMac frame. Adhesive strips are not forgiving, and rarely give multiple chances!
