Description

Technical Field

[0001] This application relates to the field of laptop keyboard backlight structure, and in particular to a setting structure that integrates a laptop keyboard and a laptop RGB keyboard backlight. Background Technology

[0002] With the continuous development of laptops, users' demands for personalization and functionality are increasing. As an important input device, the laptop keyboard not only needs to meet basic input functions, but its backlighting function is also gradually becoming a focus of user attention. RGB keyboard backlighting can provide rich color display and personalized lighting effects, bringing users a better user experience.

[0003] However, most laptop keyboards and RGB keyboard backlights on the market currently use independent designs and wiring methods. This not only increases production costs and assembly difficulty but also occupies more internal space, hindering the design of thinner and lighter laptops. In addition, independent wiring methods are prone to circuit interference, affecting the keyboard's input stability and the backlight display effect.

[0004] In traditional keyboard designs, a sandwich structure of "upper circuit board - insulating layer - lower circuit board" is typically used to achieve key row and column scanning. An additional independent backlight module is required to house the LEDs and their driving circuitry. While this design satisfies both keyboard functionality and backlighting requirements, it also results in the redundant stacking of multiple circuit boards and backlight modules, increasing manufacturing processes and assembly complexity, and leading to relatively high material costs.

[0005] To address this, a configuration structure integrating the laptop keyboard and the laptop RGB keyboard backlight is proposed. Utility Model Content

[0042] Working principle:

[0043] Key triggering working principle: When the key is triggered, the electrical signal is transmitted from the key X gold finger 203 to the key X circuit printed point A206, and then through the key X printed circuit 401 to the key X circuit printed point B211 to the key X circuit trigger disk 209.

After LED-B completes signal processing and lights up, the control signal continues from the single-point single-pass LED-B printed point C217 to the LED data line printed line B403, and then to the single-point single-pass LED-A printed point B215. LED-A completes signal processing and lights up, realizing the control and display of the RGB backlight.

[0045] This invention achieves an integrated layout of the keyboard scanning network and the single-point single-pass LED backlight circuit by sequentially arranging a conductive circuit layer 2, an insulating layer 3, and a jumper circuit layer 4 on a single-layer circuit substrate 1. In this structure, the jumper circuit layer 4 simultaneously provides the connection functions for the key X / Y channel scanning trigger circuit and the positive and negative terminals of the LEDs and data lines. The insulating layer 3, with its "window" design, exposes the conductive area only in specific gold finger or contact areas, achieving efficient and precise electrical connection. The jumper circuit layer 4 is disposed on the surface of the insulating layer 3 and, by interfacing with the gold fingers and jumper areas exposed on the surface of the insulating layer 3, forms a row and column circuit for key scanning and a backlight control data line network for backlight control. This allows the dispersed multi-channel LED control and multi-layer key scanning circuits in traditional keyboards to be compactly distributed in the stacked structure of this invention.

[0046] When a user presses a button, the button signal travels from the X gold finger in conductive circuit layer 2 to the printed circuit layer, then back to the Y gold finger to form a loop, enabling row and column scanning and detection of the button signal. The backlight LED uses a single-point, single-pass structure to cascade control signals, with power and communication provided by the LED data lines distributed in jumper circuit layer 4 and the LED positive and negative lines in conductive circuit layer 2. By opening windows in insulating layer 3 to effectively prevent short circuits in unrelated areas and precisely exposing the gold fingers or trigger pads at critical locations, robust electrical connections and highly integrated wiring are ensured even with multiple layers stacked.

[0047] By employing this multi-layered design, this invention significantly reduces keyboard thickness while minimizing interference between circuits, thus improving ease of manufacturing and installation. Utilizing the scalability of jumper layer 4, this invention also allows for the addition of more functional modules, such as additional LEDs or new sensors, to the same structure in the future, combining high integration, reliability, and flexible expandability. Overall, this invention effectively combines conductive layer 2, insulating layer 3, and jumper layer 4 to construct an RGB backlit keyboard circuit platform suitable for various application scenarios, offering advantages such as compact structure, stable signal, and ease of mass production.
