First hole can be circular hole or bar hole, following for being easy to describe, with the first hole is
Each embodiment is illustrated by circular hole.
For different word numbers, may have different word length, if civilian
Word height is constant, has only to adjust the length of bar hole in such cases, for the width of bar hole
Degree need not change the display requirement that can meet word, and still can be ensured by bar hole
The display effect of all words, therefore, for the word of different numbers, can't be to phase
The width of two adjacent indicator-lamp covers 2 causes bigger change, though namely word length increasing
Add, also will not increase the interval between adjacent two indicator-lamp cover 2, will not be at bar hole
Increase the volume to cover body 1 on width to take, therefore can preferably ensure indicator-lamp cover 2
Compact conformation, make indicator-lamp cover 2 can satisfied display require in the case of reduce cover body 1
Overall volume.
In the present embodiment, display lamp selects paster LED lamp, circle lamp to compare with SMD lamp, patch
Sheet lamp (such as model is the SMD lamp of 3528) lighting angle (lighting angle is α=55 °)
More than circle lamp lighting angle (lighting angle is α=30 °), therefore select paster LED lamp permissible

Putting, one of them arc 3 is connected to same one end of two straightways 4, another arc 3
It is connected to the other end of two straightways 4.Straightway 4 phase of two adjacent indicator-lamp covers 2
Adjacent setting, can make there is uniform interval between adjacent indicator-lamp cover 2, it is possible to clear in guarantee
Reduce the spacing between adjacent two indicator-lamp cover 2 on the basis of Chu's display indication character, subtract
The volume of little whole lampshade assembly.
Lampshade assembly also includes the digital shroud 5 being arranged on cover body 1, sets between digital shroud 5
It is equipped with the separation retaining sheet 6 for the light of two adjacent charactrons is isolated, charactron warp
After separation retaining sheet 6, the projection on display perspective plane is non-interference.Digital shroud 5 is mainly used in
The display of double 8 patterns, therefore, when the digital shroud 5 designed on lampshade assembly, needs root
The spacing between the digital shroud of adjacent two 5 is determined according to the final display image of double 8 patterns,
With the problem guaranteeing to occur ghost image, image overlapping between double 8 patterns.
Preferably, the outgoing bright finish of digital shroud 5 and indicator-lamp cover 2 is positioned at the same of cover body 1
On individual curved surface so that the outgoing bright finish of the loophole of double 8 patterns and the loophole of display lamp is positioned at
On same curved surface, it is possible to prevent owing to the reasons such as manufacturing tolerance cause the loophole of double 8 patterns
With the loophole of display lamp occur on outgoing bright finish difference in height, double 8 patterns and indication character it
Between alter light and cause ghost problems, the assembling yield improving lampshade assembly and other structures is asked
Topic, improves display effect.
The indicator-lamp cover 2 of lampshade assembly is arranged with corresponding display lamp one_to_one corresponding, it is possible to achieve
Single lamp single hole, it is possible to avoid the pattern ghost phenomena that many lamps single hole causes, improves display effect.
Lampshade assembly preferably light absorptive material is made, such as black material.Due to double 8 patterns
Loophole be generally aperture, from the point of view of the reflectorized material loophole for double 8 patterns, it may occur that
Diffuse-reflectance and the phenomenons such as ghost image occur, and select the light absorbents such as black material, then can be fine
Avoid light, through the loophole of double 8 patterns, diffuse-reflectance occurs, thus avoid double 8 patterns to go out
Existing ghost phenomena, improves the definition of double 8 pattern formings.
Also include multiple display lamp hole 12 on lampshade assembly, be used for pressure display lamp is installed.
In conjunction with seeing shown in Fig. 3 to Figure 16, according to embodiments of the invention, display device includes
Circuit board support 7, display panel 8, paster LED lamp 9, lampshade assembly and display floater 10,
Display panel 8 is arranged on circuit board support 7；Paster LED lamp 9 is arranged on display panel 8；
Lampshade assembly is arranged on display panel 8, and the indicator-lamp cover 2 on lampshade assembly is located at accordingly
On paster LED lamp 9；Display floater 10 is located at outside lampshade assembly, paster LED lamp 9
Display pattern is incident upon on display floater 10.
In conjunction with seeing shown in Fig. 4 to Fig. 6, lampshade assembly herein is by four screws and two
Locating dowel is fixed on circuit board support 7, and locating dowel height is more than 3mm, higher than display panel
The height of the paster LED lamp on 8, prevent from swiping when assembling para-position paster LED lamp 9, carries
Rise assembling yield.The concrete of locating dowel highly can be selected according to the height of paster LED lamp voluntarily,
As long as the installation of paster LED lamp can not hindered while lampshade assembly is positioned i.e.
Can.
Preferably, paster LED lamp 9 is cold light lamellar light emitting diode, for indication character or
The display of figure and double 8 patterns can have preferable display effect.Charactron is owing to show
Double 8 patterns, are limited by the installing space on display panel 8, typically all the paster of selection of small
LED 9, here chip select shape light emitting diode 3014 (cold light is white).Due to paster LED lamp
It is relatively steady that round lamp is compared in the decay of the light of 9, and lighting angle is bigger, and these can be according to specifications
Light intensity decays curve learn, therefore other pattern lamps in addition to double 8 patterns also select patch
Sheet LED 9, here chip select shape light emitting diode 3528 (cold light is white), so for display
Long strip type word and intensive effect are more preferable.
The specification of paster LED lamp 9 should be unified as far as possible, avoids selecting multiple different size as far as possible
Lamp, is so easy to the brightness uniformity of adjusting display device, adjusts each paster LED lamp 9
Luminance difference so that the last display effect of pattern is consistent.But owing to the display space of a whole page limits, for
The size of paster LED lamp 9 and display effect have different requirements, the patch of the most double 8 patterns
The specification of the paster LED lamp 9 of sheet LED and other patterns is not consistent, needs when selecting
Select the paster LED lamp 9 of two kinds of specifications.
In the present embodiment, the specification as the paster LED lamp 9 of display lamp is consistent, is used as double
The specification of the paster LED lamp 9 of the charactron of 8 pattern displaying is consistent, it is simple to unified to display lamp
Carry out brightness regulation, or the unification of logarithmic code pipe carries out brightness regulation.
In conjunction with seeing shown in Fig. 7 to Fig. 9, the light source incidence face of display floater 10 has been sticked facial film
11, facial film 11 includes light absorption unit and hyalomere, and hyalomere is corresponding with the projection of paster LED lamp 9
Arrange.Specifically, screen printing pattern transparent on the light transmission facial film 11 of paster LED lamp 9
Portion projects to the shape of display pattern on the trypsin method layer of display floater 10.The extinction of facial film 11
Portion can to irradiate light absorb, prevent irradiate light transmission during occur diffuse-reflectance and
Have influence on the paster LED lamp 9 display effect on display floater 10.Facial film 11 uses
The background color of black, the position of pattern character is processed into transparent, owing to pass through transparent display surface
Plate 10 is shown to the sprayed coating of outer surface, i.e. in be spaced one layer of medium, so needing its printing opacity
Preferable PET or the PC material of property.
As a example by the height H of the indicator-lamp cover 2 of lampshade assembly is as 5mm, on 3D drawing its
Uniformly light-emitting region is Φ 5.4mm (i.e. 26 ° to 30 ° region), and lighting angle region is Φ
10.85mm (i.e. luminous region, 26.57 ° of visual angle), when pattern (font length 12.5, width
4mm) being placed in light-emitting zone, pattern intensity is uneven, and pattern edge does not works (because all
Even luminous zone 5.4mm, and lighting angle region 10.85mm ＜ 12.5mm, it is impossible to pattern is complete
Entirely shroud in the lighting angle region of display lamp).Due to the restriction of the space space of a whole page, so by lamp
Hole is designed to slightly larger than uniformly light-emitting district, makes indication character be distributed in uniformly light-emitting district.
When design, the indicator-lamp cover 2 of lampshade assembly is funnel-form, the circular hole of indicator-lamp cover 2
The section diameter avoiding paster LED lamp is 6.5mm, more than LED pad locations 0.5mm with
On, the angle between centrage and the sidewall of indicator-lamp cover 2 of indicator-lamp cover 2 is 15 ° to 20 °
(shown in Figure 9), the height of indicator-lamp cover 2 is 12 to 16mm；The number of double 8 patterns
Gap between shroud 5 is 1.4mm, the height of the digital shroud 5 of double 8 patterns be 9 to
11mm。
In conjunction with shown in Figure 10, for the display device of the present embodiment, set actual
In the meter course of processing, the height of indicator-lamp cover 2 is typically designed as 12mm to 16mm, this enforcement
In example, the uniformly light-emitting angle design of indicator-lamp cover 2 is α=26.57 °, the height of indicator-lamp cover 2
It is designed as H=13.6mm, cd (luminous zone radius)=1.2mm, the height of paster LED lamp 9
H=1.95mm, the distance between light exit plane and the perspective plane of paster LED lamp 9
K=H-h=13.6-1.95=11.65mm, thus release ec=cd/tan α=1.2/0.5=2.4mm,
Eo=K+ec=11.65+2.4=14.05mm, can be released by triangle similar quality: cd/ob=ec/eo,
Ob=eo*cd/ec=14.05*1.2/2.4=7.025mm, so homogeneous area is diameter
The scope of D=2*ob=14.05mm, when light be irradiated to facial film pattern (font length 12.5mm,
Width 4mm), pattern displaying is uniform.When the height H of indicator-lamp cover 2 is the biggest, can be uniform
The scope of display is the biggest.Certainly H is the biggest, and the brightness of paster LED lamp 9 can be in certain journey
Weaken on degree, so to determine according to practical situation and to want display effect, thus ensureing there is foot
On the premise of enough indication ranges, paster LED lamp 9 has enough brightness.
Display floater 10 and display panel 8 are sealed at the both ends open of indicator-lamp cover 2 so that phase
It is respectively formed confined space between two adjacent indicator-lamp covers 2, is possible to prevent to be positioned at a display lamp
The light-illuminating of the paster LED lamp 9 in cover 2 is in adjacent indicator-lamp cover 2, and light is altered in generation
Phenomenon and cause ghost image, it is possible to preferably avoid between adjacent two paster LED lamp 9 occur
Interfere, more efficiently avoid ghost image and the problem of image overlap, it is ensured that the display effect of display lamp
Really.
In conjunction with seeing shown in Figure 11 to Figure 16, for double 8 sectional hole patterns, when design,
Ignore the refraction effect that paster LED lamp 9 occurs in irradiation process, from similar triangles:
AB/DE=BC/CE, wherein AB is the photograph of the hole point on digital shroud 5 and paster LED lamp 9
Penetrating the distance of centrage, DE is that paster LED lamp 9 is after the digital shroud 5 represented by AB
Imaging on display floater 10, CB is the irradiation center of paster LED lamp 9 and digital shroud
Distance between the center of 5, CE is irradiation center and the display floater 10 of paster LED lamp 9
Display surface between distance.
Data according to measuring on 3D figure:
(1) combine shown in Figure 12, adjacent for identical two of length bearing of trend
For digital shroud 5, CB=9.7mm, CE=9.7+0.35 (facial film and the thickness of double faced adhesive tape)
+ 2 (thickness of display floater)=12.05mm, AB=6.3/2=3.15mm, can release:
DE=3.91mm, i.e. D point is exaggerated relative to A point, and the distance of increase is
3.91-3.15=0.76mm, so the imaging hole point that double 8 patterns are on display floater 10 is away from least
More than 0.76*2=1.52mm, therefore the hole point distance of adjacent digital shroud 5 can be set to greatly
In imaging hole point distance, the hole point of the digital shroud of adjacent two 5 thus can be effectively prevented
Position occurs pattern to interfere.In the present embodiment, such as by two adjacent digital shrouds 5
Hole point distance is set to 1.9mm, and therefore on display floater 10 between the pattern of display between
Gap is more than 1.9mm, also just can interfere on display floater 10 much larger than double 8 patterns
Ultimate range 1.52mm, can avoid occurring pattern to interfere.
(2) combine shown in Figure 13, adjacent for perpendicular two of length bearing of trend
Digital shroud 5 for, CB=9.7mm, CE=9.7+0.35 (facial film and the thickness of double faced adhesive tape)
+ 2 (thickness of display floater)=12.05mm, FN=2.48mm, FN/ME=CB/CE, by
This can release ME=3.08mm, i.e. M point and be exaggerated relative to F point, and the distance of increase is
3.08-2.48=0.6mm, so the spacing that the digital shroud 5 of double 8 patterns is on display floater 10
At least should be greater than 0.6*2=1.2mm, therefore the minimum range of adjacent digital shroud 5 can be arranged
For more than imaging gap, the hole point of the digital shroud of adjacent two 5 thus can be effectively prevented
Position occurs pattern to interfere.In the present embodiment, such as, it is 1.4mm by the digital shroud 5 of pattern,
It is prevented that be connected, the light source in digital shroud 5 interferes after digital shroud 5 injection.
In conjunction with shown in Figure 14, when in a digital shroud 5 through two light sources, due to
The direction of illumination of two light sources is the most different, and therefore on display floater 10, the imaging of display is not the most
Equally, and overlap, result in ghost phenomena, therefore at the digital shroud 5 of design
Time, it is also desirable to make digital shroud 5 seal up paster LED lamp 9, prevent digital shroud 5 for every
Open LED light source part, cause lampshade component bottom to alter light and ghost phenomena occurs.
In conjunction with shown in Figure 16, calculate double 8 pattern lamps and irradiate safe altitude and the peace not altering light
During full gap, as a example by the charactron specification of double 8 patterns is for lamellar light emitting diode 3014, DE
Actual amount range finding from for 2.94mm, the height of digital shroud 5 is 1.5mm, layers of two-sided with
The gross thickness of facial film is 0.2mm, according to the specification of lamellar light emitting diode 3014, it is known that
CD=1.5-0.3=1.2mm, the gap between double 8 patterns of the light incident side at facial film 11 is
During 0.4mm, according to the similarity principle of triangle: CD/CB=DE/AB,
1.2/1.4=2.94/AB, AB=3.43mm, wherein the distance phase between A point and light source center line
The size increased than the distance between E point and light source center line is:
AB-DE=3.43-2.94=0.49mm 0.4mm (double 8 pattern intervals), namely light is from facial film 11
Light incident side add 0.49mm to the irradiation maximum spacing of exiting side, beyond facial film during design
The gap between double 8 patterns on 11, light can be irradiated to another adjacent with this pair 8 pattern
In individual pattern, alter optical phenomenon and produce, cause ghost image.So not allowing light transmission gap location on She Ji
It is irradiated to side pattern up, needs the irradiating angle of logarithmic code shroud 5 to limit, or
It is to strengthen the spacing between double 8 patterns adjacent on facial film 11, thus avoids lamellar light-emitting diodes
The range of exposures of pipe 3014 is more than the gap between adjacent double 8 patterns, it is to avoid in display double 8
