  • Take a peek at what powers those popping pixels:

  • Texas Instruments SN74LVC8T245 8-bit dual-supply bus transceiver

  • Texas Instruments BUF16821 programmable gamma-voltage generator and Vcom calibrator

  • Parade Technologies DP665 LCD timing controller (the same found in the last generation iMac 4K)

  • We assume this is an Apple modified version of the DP663

  • Texas Instruments TPS54218 4.5 V to 17 V input, 2 A synchronous step-down SWIFT converter

  • Texas Instruments TPS54320 4.5 V to 17 V input, 3 A synchronous Step-Down SWIFT converter

  • Texas Instruments TPS65168 high resolution, fully programmable LCD bias

Echa un vistazo a lo que mueve a esos píxeles emergentes:
