  • Apple has opted to transition from using a row of LEDs with a light guide panel, to installing individual LEDs beneath each key.

  • And behind those keys, we find:

  • An array of four Texas Instruments TLC5951 PWM LED Drivers

  • A pair of NXP PCAL6416A I/O Expanders

  • They claim that this new keyboard design provides even lighting across the whole keyboard, while maintaining a higher level of power efficiency than previous designs.

  • PCB maker Compeq reports increased revenues for March.

苹果继续选择了 LED 光导面板,在每颗按键下方都安装一颗独立的 LED 发光体。

在这些按键的下面,我们找到了:

一排四个的德州仪器 TLC5951 PWM LED 驱动器。

一对NXP PCAL6416A I/O 扩大器

他们甚至声称这个新的键盘设计可以提供整个键盘的照明,同时比之前产品的设计更加节能。
