Electronic control device with touch-sensitive led display
The patent US12057830B2 describes an innovative electronic control device (10) that integrates a sophisticated lighting and touch-sensitive interface. Central to its design is an electronic circuit (11) equipped with multiple LEDs (12) mounted on an operative face (11a). The device features a frame (13) that defines first channels (14) directing the light emitted from the LEDs towards a composite screen (15). This screen is designed with a diffuser layer (16) to ensure uniform light distribution and an operative layer (17) that includes touch-sensitive pads (18) and connection contacts (19). The device also incorporates at least one connector (20) that facilitates electrical communication between the connection contacts and the electronic circuit, enabling user interaction through touch.
Further enhancing its functionality, the composite screen (15) can be securely attached to the frame (13) using methods such as ultrasonic welding or adhesive films. The design allows for the formation of luminous signs on the screen by selectively activating the LEDs, particularly in areas corresponding to the touch-sensitive pads. The first channels (14) are organized into groups, with some configured to create a 7-segment display, while others illuminate the sensitive pads. Additionally, the composite screen may include a chromatic layer to modify the emitted light's color and a protective layer (22) that serves as the outer touch interface. This patent outlines a comprehensive approach to combining visual feedback and user interaction in electronic control devices, emphasizing both functionality and user experience.
