  • Time to take a closer look at that display. Turns out it uses the same display panel we found in the iMac 5K: LG Display model LM270QQ1.

  • That said, the cabling arrangement and webcam hardware have been moved around—so you can't swap displays between models.

  • We peel up the long strip of shielding along the bottom to reveal the chips:

  • Texas Instruments NH245 8-Bit Dual-Supply Bus Transceiver

  • Texas Instruments BUF16821 Programmable Gamma-Voltage Generator and Vcom Calibrator

  • Parade Technologies DP665 LCD Timing Controller

  • Texas Instruments TPS54320 3A synchronous step-down SWIFT™ converter

  • Texas Instruments TPS65168 High Resolution Fully Programmable LCD Bias IC for TV

是时候仔细看看这块显示屏了。可以发现这块显示屏使用了和iMac 5K同样的面板：LG显示屏，型号LM270QQ1

这说明，排线布局和摄像头被移动了——所以你不能在各个型号间随意互换屏幕。

我们沿着底部剥去长条状的屏蔽罩以把芯片显露出来：

德州仪器/Texas Instruments NH245 8位双电源总线收发器

德州仪器/Texas Instruments BUF16821可编程伽马电压发生器和Vcom校准器

谱瑞科技/Parade Technologies DP665 LCD定时控制器

德州仪器/Texas Instruments TPS543203A同步降压SWIFT™转换器

德州仪器/Texas Instruments TPS65168高分辨率完全可编程LCD偏置IC
