Despite their similar hardware, iPads continue to lag way, way behind iPhones in their construction—this home button being a perfect example. On iPhones this is an easy, elegant swap, but here it's still a mess of glue, even after all this time. Elsewhere on this display, we blast the shields off and smoke out the chips underneath:

  • Elsewhere on this display, we blast the shields off and smoke out the chips underneath:

  • Parade Technologies DP815 Display Port timing controller (likely)

  • Texas Instruments TPS65195 clock level shifter

  • Texas Instruments TPS65144 LCD Bias w/ integrated gamma reference

  • Intersil ISL24879 precision programmable LCD reference voltage generator

  • STMicroelectronics M24C64-F 64 Kb Serial EEPROM memory

Trotz ihrer ähnlichen Hardware hinken iPads nach wie vor weit hinter iPhones her was ihre Konstruktion betrifft - dieser Home Button ist ein perfektes Beispiel. Auf iPhones ist ein einfacher, eleganter Austausch möglich, aber hier muss man sich, selbst nach all dieser Zeit, immer noch durch einen Haufen Klebstoff kämpfen.

Wir sprengen die anderen Abdeckungen vom Display und unter dem aufsteigenden Rauch erkennen wir folgende Chips:

Parade DP815 (wahrscheinlich ein Zeitregler)

Texas Instruments TPS65195 Level-Shifter

Texas Instruments TPS65144 LCD Bias
