Passo 16
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:
  • 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
