Specifically, the side of each structure facing upwards is referred to as the front side, and the side facing downwards is referred to as the back side, with the aim of placing the color light-emitting keyboard on a table-board horizontally and keeping the state of the keys facing upwards. The light shielding film 30, the light guiding film 10 and the reflective film 20 are sequentially arranged from top to bottom.

The light guiding structure 11 of the light guiding film 10 is disposed on the reverse side thereof, and the color filter ink body 50 is disposed on the front side of the light guiding film 10. The reflective surface of the reflective film 20 is a front surface, and optionally, the front surface of the reflective film 20 is a white reflective surface, and the back surface is a black light leakage preventing surface. As shown in fig. 5, the colloid 22 is printed on the front surface of the reflective film 20 so as to be attached to the light guiding film 10, and the colloid 22 is printed on the edge area of the front surface of the reflective film 20 and the edge area of the opening thereon, and the colloid 22 may be 3M water gel.

In this embodiment, all the color filter ink bodies 50 are printed on the light guide film 10, and the color filter ink bodies 50 and the light guide structure 11 are respectively located on two opposite sides of the light guide film 10. The color ink body is formed by printing color filter ink on the light guide film 10.

As shown in fig. 1 and 2, the light guide structure 11 is a light guide bump, and the light guide film 10 is provided with light guide bumps in regions opposite to the light transmission windows 31 of the keys. At least one group of light guide bumps are arranged corresponding to each key light transmission window 31 respectively, the number of the light guide bumps is multiple, and the light guide bumps are distributed at equal intervals. After the keys are mounted, the middle region of the key light-transmitting window 31 corresponds to the mounting portions of the keys, and this region is referred to as a key corresponding region, and the other partial regions except the key corresponding region in the case light-transmitting window are referred to as non-corresponding regions. The light-guiding bumps are preferably arranged in an area opposite to the non-corresponding area.

As shown in fig. 2, four sets of light guide bumps are disposed in the area of the light guide film 10 corresponding to one key light transmission window 31, and the area between the four sets of light guide bumps is the area opposite to the key corresponding area.

A plurality of first light holes 21 are formed in the reflective film 20 in the width direction, and the plurality of first light holes 21 are spaced in the width direction of the light guide film 10, that is, the distance between each first light hole 21 and the two side edges of the reflective film 20 in the length direction is equal. The plurality of first lamp holes 21 and the plurality of second lamp holes 12 are arranged in a one-to-one correspondence.

As shown in fig. 10, the LED light bar 41 includes a plurality of LED emitters, and the number of the LED emitters is greater than or equal to the number of the first light holes 21. Each LED light emitter passes through the first lamp hole 21 and extends into the second lamp hole 12, and at least one LED light emitter is accommodated in each second lamp hole 12. For example, the number of the LED luminaries is equal to the number of the second light holes 12, and after the plurality of LED luminaries are respectively inserted into the corresponding second light holes 12, each second light hole 12 contains one LED luminary. Or, in another specific embodiment, the number of the LED luminaries is twice as many as the number of the second lamp holes 12, and after the plurality of LED luminaries are respectively inserted into the corresponding second lamp holes 12, two LED luminaries are accommodated in each second lamp hole 12. Optionally, the light emitting directions of the two LED luminaries are opposite, the LED luminaries located on the left side emit light to the left side, and the luminaries located on the right side emit light to the right side.
