Embodiment
See also shown in Figure 1ly, the light-emitting diode display 10 that this creation disclosed is in order to be assembled on the electrical home appliances 20.It has the function of display text or figure.And except that the graphic product that discloses, the LCD display 10 that the utility model disclosed is also configurable at computer equipment, electronic device or communication facilities or the like product.
See also shown in Figure 2ly, this LCD display 10 is that form in a side can be in order to the display surface 12 of display text and figure, and the another side relative with this display surface 12 then is equipped with plural pin 14.This plural number pin 14 is in order to being plugged on the circuit board 16, links with the set circuit of circuit board 16 by this, can make this display surface 12 demonstrate literal and figure.
One light guide plate 30 is to be fitted on the casing of household appliances 20, and to display surface 12 that should light-emitting diode display 10.It should be noted that the material that this light guide plate 30 is light-permeables is made.Be fitted in technology on this casing for this light guide plate 30 in addition, can be by the general mode that fastens the location, or chimeric mode all can, only this structure and technology partly is not this case technical characterictic, so do not set forth.
At least to there be a projection source 40 to enter this light guide plate 30 in order to throw light.This projection source 40 has illuminating part 42 and pin portion 44.Wherein this pin portion 44 can form with this circuit board 16 and be electrically connected, or directly being plugged on this circuit board 16, this illuminating part 42 then correspondence or embeds the side of this light guide plate 30 in a side of this light guide plate 30, so can when projection source 40 is luminous, ray cast be entered in the light guide plate 30.
According to present light source product, above-mentioned projection source 40 can be the LED source of general kenel (LED Lamp), or surface mount device light source (SMDLamp) 50 as shown in Figure 3.This SMD Lamp 50 need form with this circuit board 16 equally and be electrically connected, and the illuminating part 52 of this SMD Lamp 50 is equally to should light guide plate 30 1 sides, or embeds this light guide plate 30.No matter to be that LED Lamp or SMD Lamp can have a plurality of for the projection source 40 that disposed of these light guide plate 30 1 sides again, and different light sources can have different colours light.
In the foregoing description, this projection source 40 provides light, and ray cast is entered in this light guide plate 30, and light can make this light guide plate 30 form the light curtain with honorable color after these light guide plate 30 internal reflections and appearing at this moment.And this light guide plate 30 is if set the projection source 40 of plural different colours, and the order of conversion plural number projection source 40 throw lights, or throw light simultaneously together, under then can changing in the order of light or mix, the light curtain effect that this light guide plate 30 is presented has multiple different display effect.
See also shown in Figure 4, light 41 is through once reflection, can pass this light guide plate 30 and be radiated on the display surface 12 of this LCD display 10, the light of this moment and this display surface 12 surface colors produce immixture, so the light that is reflected again by this display surface 12 can show another kind of color effects again after appearing this light guide plate 30.For clear the light travel condition is described among the above-mentioned figure, so ignore the light refraction effect that different medium produced of passing through.Only ignore the light refraction phenomenon and can't influence the effect that this light guide plate 30 forms the light curtain.
Yet for the light 41 that projection source 40 is provided can reflect and optically focused really, can be by etching or texture or other processing mode, surface system in this light guide plate 30 sets out transmitting construction 31, so that light curtain effect is more even, and can improve the conductivity of light source.
Except the aforementioned configuration state that projection source 40 is configured in these light guide plate 30 1 sides, this projection source 40 can also be with other form to should light guide plate 30.See also shown in Figure 5ly, this projection source 40 is that group is located at this circuit board 16, and two sides of this light guide plate 30 are formed with extension 32, and the end place of this extension 32 points to this circuit board 16 for good.This moment, the illuminating part 42 of this projection source 40 can be to extension 32 that should light guide plate 30, or embedded in this extension 32.And because the face of mainly looking 34 of this extension 32 and this light guide plate 30 has the angle angle, therefore mainly look 34 in face at this extension 32 and this and can establish a reflecting surface 36, the light of this projection source 40 can reflect after advancing to this reflecting surface 36 and enter this and mainly look face 34 in view of the above, and reaches the effect that makes this light guide plate 30 form the light curtains.Above-mentioned reflecting surface 36 can be made into inclined plane shape, also can be made into the curved surface shape, more can use the reflecting effect that improves light at outside surface be sticked lighttight reflecting piece or reflective sheeting.
The light guide plate 30 that the disclosed textural association of the various embodiments described above all can reach display surface 12 the place aheads that make this light-emitting diode display 10 forms light curtain effect.But and on reality is used more the fit adjustment device and reach the demonstration tone of expection with of the brightness of control projection source 40 with this light-emitting diode display 10.In other words, the disclosed light guide plate 30 of the utility model is in order to different printing opacity colors to be provided, make the user according to this when use sets the utility model product, can visually obtain the variation on the color, and the display effect of the existing disclosed display of technology does not have the disclosed light curtain of the utility model effect, and therefore display of the present utility model is significantly different with the display of prior art.And the design and the use of the light guide plate 30 of the utility model, with the use of the disclosed light guide plate of publication case described in the prior art and inequality.
In sum, the inventor has reached the inventor's goal of the invention by the enforcement of technique scheme.
