Color difference, backlight impurity and optical crosstalk, and suitable for the big character touch key-press 12 of single led 141 control.
In the present embodiment, it is preferable that as shown in figure 5, light source 14 is LED141, in other embodiments, light source 14 can be with
For LCD etc., the use of light source 14 simultaneously not only limits the present embodiment.
It should be noted that the shape of touch key-press 12 is circle, it specifically, can be depending on specifically used situation.
With refining, the quantity of LED141 is multiple, and each LED141 is independently arranged, and every LED141 is correspondingly provided with a back
Photo structure 15 and a touch key-press 12.In this manner it is achieved that multiple multiple touch key-press 12 of LED141 independent control, it can adopt
Backlight is carried out to touch key-press 12 with the LED141 of different colours, so that the display effect of touch key-press 12 is more colorful, so that
The flexibility of backlight control is bigger.
As shown in figure 8, there is assembly errors for meeting, and make panel due to when assembling panel 11 and backing structure 15
There are gap or existing gap are excessive between 11 and the upper plane 151 of backing structure 15, excessive gap will affect panel 11
Therefore the touch-control effect of upper touch key-press 12 in order to eliminate the gap, is equipped between the backing structure 15 and the pcb board
Soft layer 16, the LED are placed through in the soft layer 16, the panel 11, the backing structure 15, the soft layer 16 and
The pcb board 13 is sequentially bonded, and mutually forms interference fit.
As shown in Figures 3 to 5, in order to enable the light that is issued to LED141 of backing structure 15 is dispersedly more uniform, back
Photo structure 15 has plane 151 on one, and upper plane 151 is parallel with the plane of panel 11 and 13 plane of pcb board, in this way, pcb board
The light that LED141 is issued on 13 is first projected via plane 151 on backing structure 15, and is projected perpendicular to upper plane 151 exhausted big
Some light will be vertically projeced on panel 11 on touch key-press 12, finally in backlight on touch key-press 12, therefore, backlight
The upper plane 151 of structure 15 is parallel with 11 plane of panel, advantageously reduces the loss of light propagation, is conducive to enhance touch key-press
The brightness of backlight on 12；Importantly, since most light are projected perpendicular to upper plane 151, and along light propagation
Therefore route perpendicular projection, reduces light and projects other touch key-press on the facing touch key-press 12 of upper plane 151
The generation of the optical crosstalk phenomenon caused on 12.
It should be noted that backing structure 15 is white clear material, it is preferable that backing structure 15 is white clear modeling
Glue.
As shown in Figure 4 and Figure 5, in order to which the light for issuing backing structure 15 to LED141 disperses
Even, upper plane 151 is equipped with the finely dispersed diffusion layer 152 of light for will be projected by upper plane 151.In this way, by
The light of LED141 transmitting is first via 151 astigmatism of plane injection on backing structure 15 and then further uniform via diffusion layer 152
Astigmatism.
On 151 position of upper plane just faced due to LED141, the brightness of backlight is larger, therefore, in order to enable upper plane
Whole backlight is soft, uniform on 151, and LED141 is set on the position for just facing upper 151 center of plane on pcb board 13, and is dissipated
Photosphere 152 is covered on center.
Refinement ground, 152 quantity of diffusion layer is multilayer, in this way, can be according to the difference journey at upper 151 center of plane and surrounding brightness
Degree successively increases setting diffusion layer 152, subject to the above 151 Center-to-Center surrounding brightness of plane is uniform.
As shown in Figures 3 to 5, in order to enhance the backlight intensity on touch key-press 12, pcb board 13 is covered by backing structure 15
Region be equipped with reflective layer 142 for reflecting light towards upper plane 151.
Since in the light that LED141 launches, a part transmits away via the upper plane 151 of backing structure 15, one
Part reflects back into bottom surface by the medial surface of upper plane 151 and surrounding wall, that is, returns to the region covered by backing structure 15
On, and in adding reflective layer 142 on the region, be conducive to the light that will be reflected on the region is reflected back plane 151 again,
It transmits away via upper plane 151, in this way, being increased by the light that upper plane 151 transmits away, is projeced on touch key-press 12
Light will also increase, and therefore, enhance the backlight intensity on touch key-press 12.
As shown in figure 8, the backing structure 15 covers at described for the light uniform transillumination for issuing LED141
The surface of the periphery LED141 is a smooth surface 153.In this way, light a part that LED141 is issued is saturating via smooth surface 153
It being shot out, a part reflects back on LED141 and reflective layer 142 via smooth surface 153, and due to 153 table of smooth surface
Face is smooth, can reduce the diffusing reflection of light, so that reflecting back into the light on reflective layer 142 by smooth surface 153 will increase, because
This, being reflected back the light on smooth surface 153 by reflective layer 142 will increase, then transmit away via smooth surface 153, due to
Project every time light on smooth surface 153 all some transmit away, a part reflects back, and light is in smooth song
Constantly round-trip transmitting, will be continuously increased the light of transmissive portion between face 153 and reflective layer 142, generally speaking, reach enhancing back
Luminous intensity improves the effect of backlight effect.
Specifically, the section of smooth surface 153 is parabola, in this way, the light gone out via 153 surface transmission of smooth surface
Line, the angle of emergence is vertical with section parabola, therefore, will be more uniform via the light that smooth surface 153 is emitted, and is conducive to
Even back.
Preferably, in the present embodiment, smooth surface 153 is spherical surface, and in other embodiments, smooth surface 153 can also be
Ellipsoid.
In order to guarantee that the light being reflected back on reflective layer 142 by smooth surface 153 is all reflected back on smooth surface again,
The region area covered by the backing structure 15 on the pcb board 13 is less than or equal to the area of the reflective layer 142, i.e.,
The region area that smooth surface 153 is covered be less than reflective layer 142 area, and the region area that backing structure 15 is covered again smaller than
Or the area equal to touch key-press 12, be conducive to enhance touch-control effect in this way.Due to being installed on pcb board by backing structure 15
When, it is easy to smooth surface 153 and the inaccurate situation of LED141 contraposition occurs, therefore, in order to enable smooth surface 153 with
LED141 contraposition is accurate, and the backing structure 15 covers on the surface of the periphery LED141 and is convexly equipped with angle 154, positions
The two sides or periphery of 154 smooth surfaces 153 of foot, and through soft layer 16 and be inserted on pcb board 13, in this way, in backlight knot
The region area that structure 15 is covered again smaller than or equal to touch key-press 12 area, and backing structure 15 tend to miniaturization, it is miniature
In the design of change, due to not easily causing dislocation or positioning inaccurate using angle 154 yet.
In addition, as shown in Figures 3 to 6, in order to enhance the backlight intensity on touch key-press 12, it is also possible that in panel 11
On side in be convexly equipped on the periphery of touch key-press 12 for enhance light reflection the first enclosure wall 111.
During light is transmitted by upper plane 151 and is projeced on touch key-press 12, it will form with touch key-press
Optical path centered on 12, due to the setting of the first enclosure wall 111, so that optical path will become smaller adjacent to the region of touch key-press 12, optical path
It is equal with the region carried out by the first enclosure wall 111, it is approximately equal to the region where touch key-press 12, moreover, because projecting first
Light on enclosure wall 111 will be reflected back in 12 region of touch key-press by the first enclosure wall 111, in this way, being also beneficial to increase
The backlight intensity of strong touch key-press 12.
Certainly, similarly, as shown in Figures 3 to 5, in order to enhance the backlight intensity of touch key-press 12, in back on pcb board 13
The periphery of photo structure 15 is equipped with the second enclosure wall (not shown) for enhancing light reflection.In this way, saturating via backing structure 15
It projects, and the light being transmitted on the second enclosure wall will be reflected back centered on plane 151 on backing structure 15 by the second enclosure wall
In optical path, in this way, the light projected via backing structure 15 will also increase, the light being projeced on touch key-press 12 also increases therewith
Add, in short, being conducive to enhance the backlight intensity of touch key-press 12.
In order to enable the 12 region backlight of light touch key-press being projeced on panel 11, in touch key-press 12 on panel 11
Periphery it is opaque.
