Document Type and Number:
WIPO Patent Application WO/2023/202135
Kind Code:
A1
Abstract:
Disclosed in the present application are an input device with keys, and an electronic device. The input device comprises: a mounting plate, which is provided with key holes; key modules, which are elastically and telescopically arranged in the key holes; a circuit board, which is arranged at the bottoms of the key modules and configured to receive an input instruction after the key modules are pressed; a backlight module, which is arranged at the bottom of the circuit board and configured to provide backlight for the key modules; and a color-changing member, which covers a backlight light path irradiated by the backlight module and is configured such that the color of the backlight passing through the color-changing member can be converted so as to emit backlight of at least two colors to the external environment. In the input device in the present application, the component that achieves the color-changing effect is the color-changing member, so that the requirement for selection of the backlight module is reduced, and a single-color light source, which has a lower cost than a multi-color light source, can be used, so as to achieve a multi-color key backlight effect with a low cost.
