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

ディスプレイを詳細に見ていきましょうiMac 5Kに搭載されていたものと同じパネル(LG ディスプレイモデル番号LM270QQ1)が使用されていることが判明しました。

ところが、ケーブル配置やwebcamハードウェアがあちこちに散らばっていますーつまり、モデル間でのディスプレイ交換は不可能です。

チップを確認するため、底にシールドで隠された長いストリップを剥がします。
