Abstract: A display may be mounted within an electronic device housing. The display may deflect inwardly when pressed by a user. A sensor formed from a flexible printed circuit may measure capacitance changes associated with inward deflection of the display. A backlight for the display may have a backlight plate on which the printed circuit is mounted. The backlight plate may be formed from a fiber-composite material such as carbon fiber. Multiple carbon-fiber layers may be sandwiched together to form the backlight plate. An electromagnetic shield layer may be used to electromagnetically the printed circuit. The backlight plate may have an opening in which conductive material is placed to short the electromagnetic shield layer to a ground pad on the printed circuit.

Abstract translation: 显示器可以安装在电子设备外壳内。 当用户按压时，显示器可能向内偏转。 由柔性印刷电路形成的传感器可以测量与显示器的向内偏转相关联的电容变化。 用于显示器的背光源可以具有安装印刷电路的背光板。 背光源板可以由诸如碳纤维的纤维复合材料形成。 多个碳纤维层可以夹在一起以形成背光板。 电磁屏蔽层可用于电磁印刷电路。 背光板可以具有开口，其中放置导电材料以将电磁屏蔽层缩短到印刷电路上的接地焊盘。
