Description
Technical field
The utility model provides a kind of reflection of backlight module and illuminated keyboard, espespecially light guide plate applied to illuminated keyboard
It is the reflecting part provided with correspondence button assembly, the continuous lines that the reflecting part is constituted for multiple sites for mutually concatenating on face
Bar structure, can more effectively improving optical extraction intensity, and then improve the mean flow rate of light guide plate.
Background technology
The fast development of electronics technology and information industry now, makes various electronic products all towards light, thin, short, small and work(
The powerful trend development of energy, such as computer, notebook computer, mobile Internet access device (MID), intelligent mobile phone, tablet PC
Deng, it has also become modern's electronic product indispensable in daily life or work, and it is big between user and electronic product
It is to be linked up using input equipments such as mouse, keyboards mostly, wherein the most conveniently making the input of word, numeral or instruction with keyboard again
Operation, and lift the function of practicality.
For the symbol that in the environment of insufficient light human eye can be clearly seen that on each button, just there is technical staff
Light guide plate and light source technology are imported in keyboard, and develops the backlight keyboard of tool backlight module, produced by making backlight module
Light, which can be projected, forms backlight effect at the back side of each keycap, allow user to see the character symbols on keycap, with
Conveniently operate with, and backlight keyboard on the market includes key-press module and backlight module at present, wherein the backlight module is
With a light guide plate, and provided with light source at light guide plate side, and the light emitting diode of light source is to project light extraction towards light guide plate
Line makes light guide plate uniformly light, and light guide plate lower surface is provided with that the light emitted by light guide plate lower surface can be reflected back and led in addition
Reflecting piece on tabula rasa, and the anti-dazzling screen corresponded at key-press module is provided with light guide plate upper surface, just light guide plate can be drawn
The light for leading injection passes through the transmittance section of anti-dazzling screen, reenters to be incident upon on the corresponding keycap of key-press module and forms backlight.
However, the light source that backlight module is used can be divided into two kinds of straight-down negative and side-light type, because side-light type is more easily implemented
Slimming design, so using upper relatively broad, but the light emitted by light emitting diode is conducted to rear from guide-lighting front edge of board
During end, the brightness of its light can gradually decay, and cause the corresponding button character symbol in light guide plate rear end to produce luminance shortage
Phenomenon, therefore in recent years person skilled in order to solve the light skewness of light guide plate conduction, mean flow rate is not enough
Problem, just molds multiple micro-structurals on the bottom of light guide plate or reflecting surface, light is led to when being conducted inside light guide plate
The conduct route that those micro-structurals change light is crossed, light-ray condensing can be uniformly reflected in each button with providing light guide plate
On.
Refer to Fig. 7, shown in 8, existing illuminated keyboard is includes backlight module A and connection component B4, the wherein back of the body
Optical module A light guide plate A1 lower surfaces are provided with a reflector plate A2, and are provided with an anti-dazzling screen A3 in light guide plate A1 upper surfaces, and adjacent
Light source A4 light emitting diode A41 is provided with light guide plate A1, and the button assembly B at backlight module A tops is to include one
Bottom plate B1, a film circuit board B2, a keycap B3 and a connection component B4, and film circuit board B2 is arranged at bottom plate B1 and key
Between cap B3, keycap B3 is arranged on bottom plate B1 by connection component B4, and provided with can between film circuit board B2 and keycap B3
Elastic parts B5 for pushing and triggering corresponding thin film switch.
Multiple site A11 micro-structurals that the site block A10 of light guide plate A1 lower surfaces designs for discrete type, it mainly leads to
The spacing for crossing multiple site A11 reaches the adjustment of optics extraction with total (dot density ≡ sites number/unit area), especially
It is that, at the long-range place apart from light source A4, because light guide plate A1 light conductions is distant, the density of energy is relatively low, just needs
Higher site A11 density improves optics extraction yield, but to be limited to light guide plate A1 final site A11 be to be pressed using heat is (flat)
Or hot rolling technology, and under conditions of light guide plate A1 temperature and pressure is given, by the discrete topology figure on male model with face pressure
Power contacts transcription to a light guide plate A1 side surface.
When light guide plate A1 is in place of the A11 very high densities of site, due to forming temperature (such as 165 DEG C) and pressure (such as 60kg) all
Raising can not be coordinated again using under the limitation of material or forming bench by being limited to light guide plate A1, and will produce can not transcription completely
Situation occur, the art often defined with " transcription rate " whether reach transcription specification requirement, micro- knot of such a discrete type
The transcription rate of structure is at light source A4, and site A11 density is relatively low, and its transcription rate can reach 90~95%, but from light source
The site A11 density of A4 remotely is of a relatively high, and its transcription rate will drop to 50~60%, that is, reach light guide plate A1's
The limit of discrete topology patterning optical extraction, therefore light guide plate A1 brightness can not be improved by increasing site A11 density again,
Cause the exiting surface brightness of light guide plate 11 still not uniform enough, as need to be engaged in this journey technical staff and desire most ardently redesign
Key point.
