[0028] Example:

[0029] As attached Figure 1 To Attachment Figure 6 As shown:

[0030] A keyboard backlight module with colorful AI keys comprises a shading film 1, a light-guiding film 2, a reflecting film 3, an LED lamp 4, and an FPC circuit board 5, which are arranged in sequence from top to bottom. The areas of the shading film 1 and the reflecting film 3 are both larger than those of the light-guiding film 2. The shading film 1 and the reflecting film 3 seal and cover the edge sides of the light-guiding film 2, which can effectively prevent light leakage from the side of the light-guiding film 2, so that the light energy in the light-guiding film 2 is more concentrated. A light-guiding microstructure 13 is arranged on the light-guiding film 2, and the light-guiding microstructure 13 adopts an optical destruction structure, which can make it easier for light to propagate in the light-guiding microstructure 13 and reduce light loss. A plurality of key position light-emitting units are arranged at intervals on the shading film 1, and a shading ink layer 9 is arranged around the light-emitting edge of the key position light-emitting unit to prevent light leakage at the edge of the key position light-emitting unit, so that the light emitted by the key position light-emitting unit has a stronger light effect. The FPC circuit board 5 is attached to the reflecting film 3, the existing settings are to attach the FPC circuit board 5 to the side below the reflective film 3, and a number of LED lamps 4 are arranged on the FPC circuit board 5. The LED lamp 4 adopts a micro LED lamp, which is relatively expensive. It is arranged on one side of the backlight module to effectively save costs. The reasonable distribution of the LED lamp 4 can also meet the backlighting effect requirements of the backlight module. Specifically, the light energy emitted by the LED lamp 4 is maximized by sealing and covering the edge side of the shading film 1 and the reflective film 3 and the shading ink layer 9 surrounded by the key position light emitting unit. The setting of the light guide microstructure 13 can evenly distribute the light to each key position light emitting unit, so that the AI ​​auxiliary key light emitting unit 10 far from the light source, other key position light emitting units and the AI ​​key light emitting unit 6 close to the light source can all emit uniform backlight, thereby improving the overall backlighting effect of the backlight module.

[0031] The key position light emitting unit is provided with an AI key light emitting unit 6 located at the lower right side of the light shading film 1, a light shading layer 7 is provided on the AI ​​key light emitting unit 6, a colorful patch 8 located above the light shading layer 7 is attached to the AI ​​key light emitting unit 6, one of the LED lamps 4 is located directly below the AI ​​key light emitting unit 6, the light shading layer 7 and the LED lamp 4 correspond to each other, the area of ​​the light shading layer 7 is larger than the area of ​​the LED lamp 4, and smaller than the light emitting area of ​​the AI ​​key light emitting unit 6. Specifically, the AI ​​key light emitting unit 6 adopts the setting of the light shading layer 7, and other LED lamps 4 are also above the light shading layer 7. By setting up a shading layer 7, the shading layer 7 can block the direct light emitted by the LED lamp 4, reduce the intensity of the low beam, increase the luminous effect of the light-emitting units at farther keys, and evenly distribute the light to the unblocked light emitting parts of the AI ​​key light emitting unit 6 and other key light emitting units. At the same time, a colorful patch 8 corresponding to the luminous color of the AI ​​key is set on the AI ​​key light emitting unit 6, so that the AI ​​key emits uniform colorful light, which is convenient for users to identify. Different ink layers can also be printed on the colorful patch 8 to change the luminous color of the AI ​​key at any time according to customer needs.

[0032] Among them, a plurality of AI auxiliary key light emitting units 10 are arranged at one end of the light-shielding film 1 away from the AI ​​key light emitting unit 6, and a layer of color ink is printed on the AI ​​auxiliary key light emitting unit 10. Printing color ink can make the AI ​​auxiliary key emit light of various colors, which is convenient for user identification and improves the operability of the AI ​​auxiliary key. At the same time, different colors of ink layers can be printed according to needs.

[0033] Among them, corresponding openings 14 are opened on the reflective film 3 and the light-guiding film 2, and the LED lamp 4 is embedded in the opening 14. When the LED lamp 4 is embedded in the opening 14, the reflective film 3 reflects the light emitted by the LED lamp 4 as much as possible, and the light-guiding film 2 can effectively utilize the light energy emitted by the LED lamp 4 to prevent the diffusion of light, and maximize the utilization of the light emitted by the LED lamp 4. At the same time, the embedded setting reduces the spatial thickness of the LED lamp 4, which is in line with the lightweight design of the backlight module and improves the user's comfort experience.

[0034] Among them, a number of heat dissipation holes 11 are correspondingly opened on the shading film 1, the light guiding film 2 and the reflective film 3, and a black shading layer is provided around the hole wall of the heat dissipation hole 11. The heat dissipation hole 11 can assist the light guiding film 2 in dissipating heat to prevent the light guiding performance from being affected by excessive temperature; a black shading layer is provided around the hole wall of the heat dissipation hole 11 to prevent light leakage from the side wall of the heat dissipation hole 11, which helps to improve the light guiding effect of the light guiding film 2 and improve the overall luminous effect of the backlight module.

[0035] Among them, an ink shading layer 15 located around the LED lamp 4 is attached to the FPC circuit board 5. The setting of the ink shading layer 15 is to prevent light leakage from the bottom of the LED lamp 4, make full use of the light emitted by the LED lamp 4, and further improve the overall luminous effect of the backlight module.

[0036] Among them, an elastic transparent film 12 is arranged on the shading film 1 and is located above the colorful patch 8. After the backlight module is installed on the AI ​​keyboard, the setting of the elastic transparent film 12 makes the AI ​​key have a more comfortable rebound feel, thereby improving the user's comfort with the AI ​​keyboard.
