摘要： This application relates to a dynamic lighting circuit for a keyboard of a computing device. The lighting circuit described herein includes several light emitting diode (LED) drivers having multiple channels for controlling multiple LEDs. The lighting circuit also includes an electrically erasable read-only memory (EEPROM) for storing configuration data for the LED drivers. Each LED is configured to individually illuminate a single key of the keyboard, allowing the lighting circuit to modify the brightness of each key without affecting the brightness of other keys. In this way, more lighting schemes are available for the keyboard, while also providing a thinner mechanical design for the keyboard. Lighting schemes can include illuminating a group or groups of keys at a different brightness level than other keys that are not contained in the group. Additionally, lighting schemes can include animations executed by varying the brightness levels of keys over a period of time.
摘要翻译：本申请涉及用于计算设备的键盘的动态照明电路。本文描述的照明电路包括具有用于控制多个LED的多个通道的几个发光二极管（LED）驱动器。照明电路还包括用于存储LED驱动器的配置数据的电可擦除只读存储器（EEPROM）。每个LED被配置为单独地照亮键盘的单个键，允许照明电路修改每个键的亮度而不影响其他键的亮度。以这种方式，更多的照明方案可用于键盘，同时还为键盘提供更薄的机械设计。照明方案可以包括以与组中不包含的其他键不同的亮度级别照亮一组或多组键。此外，照明方案可以包括通过在一段时间内改变键的亮度水平而执行的动画。

摘要： Keyboard assemblies having reduced thicknesses and methods of forming the same. A keyboard assembly may include a printed circuit board (PCB) and a single membrane sheet adhered directly to the PCB. The single membrane sheet may substantially cover the PCB. The keyboard assembly may also include a group of dome switches coupled directly to the single membrane sheet. Another keyboard assembly may include a group of conductive pads and a group of membrane pads. Each of the group of membrane pads may be adhered directly to a corresponding one of the group of conductive pads. The keyboard assembly may also include a group of dome switches coupled directly to the membrane pads. Each of the group of dome switches may be coupled directly to a corresponding one of the group of membrane pads.
