It is the holding state of the electronic equipment of the embodiment of the present invention and the design sketch of use state refering to Fig. 1 a~1c.Electricity
Sub- equipment includes housing, push-button unit and electronic component etc., and push-button unit includes compound under touch-screen 50 and touch-screen 50
Backlight assembly (not shown), touch-screen 50 is fixed on the upper surface of housing, the light extraction of composite backlight component by modes such as stickups
Set facing to touch-screen 50 and in contrast.Under holding state, backlight assembly does not work, keyboard ＆ display region in appearance with
Other parts indistinction (such as Fig. 1 a)；When user touches the respective keys region on touch-screen 50, the backlight of electronic equipment
Component operation, the first virtual key group (such as including letter or number key) is to show (such as Fig. 1 b), and user can touch
Corresponding virtual key is operated and (such as carries out operation of typewriting)；When needing to call (music is such as played with another group of function
Related function) the second virtual key group when, user can as needed control button unit switch over it is (tactile such as switching
Originating party formula can be the modes such as infrared induction), make keyboard ＆ display region show corresponding second virtual key group (as schemed
1c)。
As shown in Fig. 2 the composite backlight component of the embodiment of the present invention includes the first light guiding film 10, the second light guiding film 20, the
The first pattern groups 10s is provided with one backlight 1 and the second backlight 2, the first light guiding film 10, for the light by irradiation thereon
Diffuse to the first pattern groups 10s；Second light guiding film 20 is arranged at the first light guiding film 10, and (present invention definition is close to composite backlight below
The direction of component exiting surface for " on ", the direction away from composite backlight component exiting surface for " under ", i.e., with the phase of the second light guiding film 20
Than exiting surface of first light guiding film 10 closer to composite backlight component), it is provided with the second pattern groups 20s, the second light guiding film
20 are used to the light irradiated thereon diffusing to the second pattern groups 20s；First backlight 1 is close to the first light guiding film 10 and set, and uses
In for the first light guiding film 10 provide backlight；Second backlight 2 is close to the second light guiding film 20 and set, for for the second light guiding film 20
Backlight is provided；The corresponding region relative with the second pattern groups 20s is offered for the second pattern groups 20s hairs in first light guiding film 10
The first through hole 11 that the light gone out passes through.
Wherein, the first backlight 1 and the second backlight 2 are respectively arranged on the not homonymy in composite backlight element width direction, and
First backlight 1 and the second backlight 2 are respectively arranged at the lower surface of the first light guiding film 10 and the second light guiding film 20, it is possible to understand that
, in other embodiments, the first backlight 1 and the second backlight 2 can also be separately positioned on the first light guiding film 10 and
The both sides of two light guiding films 20.
Anti-dazzling screen 30 is provided with the bottom of composite backlight component, anti-dazzling screen 30 is specifically close to the following table of the second light guiding film 20
Face, for avoiding going out through the light leakage that the lower surface of the second light guiding film 20 is sent, reduces light utilization and causes light pollution.
It is arranged between the first light guiding film 10 and the second light guiding film 20 on lighttight dividing plate 40, dividing plate 40 and the second figure
Corresponding region relative case group 20s offers the second through hole 41 for the second pattern groups 20s light break-through sent, dividing plate 40
In the presence of optical crosstalk between the first light guiding film 10 and the second light guiding film 20 can be avoided, display effect is influenceed.First light guiding film 10 is close to
In the lower surface of touch-screen 50.The light that second backlight 2 is sent is diffused into corresponding second pattern groups through the second light guiding film 20
20s, the light that the second pattern groups 20s is sent is successively through the first through hole on dividing plate 40 on second through hole 41 and the first light guiding film 10
11 are transmitted on touch-screen 50.Dividing plate 40 is preferably steel disc, can be fixed on the housing of electronic equipment, strengthens the peace of backlight assembly
Fill reliability.
The composite backlight component of the embodiment of the present invention using double layer light-guiding film design, optionally make the first light guiding film or
