  • To the naked eye, this display doesn't look all that different from previous generations. And with a resolution of 264 ppi, it's not the first Retina display iPad.

  • All the same, 120 Hz is a blisteringly fast refresh rate for this many pixels, which is probably why it needs four (!) connecting cables. (Its ginormous older brother got by with just two.)

  • The slimmer bezel and True Tone tech also set this display apart—but we're here for the guts. After melting off a couple shields, we find:

  • Intersil ISL24882B TFT-LCD Vref generator/programmable gamma buffer (likely)

  • Parade Technologies DP825 timing controller (likely an upgraded version of Parade ICs we've spotted in previous iPad Pros)

  • Texas Instruments TPS565158 display power management

  • Texas Instruments TMP456 remote/local temperature sensor

从肉眼看，这个屏幕看起来和前几代比起来并不是那么的不同。它的分辨率是264ppi，这并不是第一台高清视网膜屏幕的iPad。

同样，120hz是对于那么多像素点来说一种超前的刷新率。这就是为什么这块屏幕需要4（！）条连接电缆。（它的大哥哥得到了只有两条。）

与此同时，更薄的面板和True Tone（自适应环境光调节）技术将这块屏幕分开-我们的目的就是来找刺激的。当我们融化了这一对“护盾”后，我们找到了：

英赛尔 23882B R703CM

普瑞科技 DP825 定时控制器（就像是旧款iPad Pro上的升级版）

德州仪器 TPS565158
