Description
Technical field
The utility model is the device of a kind of backlight module that improves display panels colour mixture when showing, it is meant a kind of by offering recess in the light guide plate appropriate location, so that light emitting diode sends coloured light time of different colours at the same time, this different colours coloured light unlikely generation diffusion phenomenon being arranged and cause the color colour mixture, and then make the user when watching display panels, can be by the clear device that shows the caution effect of different color light color region, to remind the user.
Background technology
More and more many now electronic products are when showing; use display panels to come display result; more wish to come display result with the background of different colours; with as the caution; make the user learn the result easily and deepen the impression by the different colours block, for example: red expression value of being above standard or setting value, and green expression is normally or the general standard value; and yellow is near dangerous values, need give special heed to ... Deng.
But general display panels; please refer to Fig. 1; shown in Figure 2; it is the display panels of a kind of use at electronic sphygmomanometer; it mainly is arranged on a housing 50 surfaces; but this display panels 70 display digits or literal or pattern; this display panels 70 has a reflecting plate 100 again; and 70 stacked light guide plate 90 of this reflecting plate 100 and display panels; these light guide plate 90 1 sides are embedded with two light emitting diodes (LED) 80; again; described light emitting diode 80 can produce the coloured light that has of different colours; and 80 of described light emitting diodes keep certain distance; and coloured light that this light emitting diode 80 is produced can be by the background display effect of light guide plate 90 and reflecting plate 100 reinforcement display panels 70; described again light emitting diode 80 can be complied with predefined demonstration normal or prompting or dangerous light color respectively in the blood pressure measuring result by the user; as normotensive value is that green cresset shows; near dangerous values is that yellow cresset shows, surpasses dangerous values and then shows with red cresset.
This kind device construction in use; as the hypertension value that the user measured is normal; but the low blood pressure value is when surpassing dangerous values; then respectively by light emitting diode 80 produced green and red when having coloured light to be projeced into the back side of display panels 70 respectively via light guide plate 90 and reflecting plate 100; the coloured light that produces because of light emitting diode 80 is when outside projection; it is outwards diffusion gradually at a certain angle; so; the coloured light that the adjacent area of described light emitting diode 80 on light guide plate 90 have different colours takes place and overlaps in regular meeting; and then there is the effect of colour mixture to produce; and then it is unclear to cause the user to watch; can't effectively reach the purpose of strengthening the caution user, therefore very undesirable in the use.
Summary of the invention
Because the disappearance of the backlight module display device of the display panels of aforementioned known electronic device, the creator is the device of colour mixture when working out the backlight module that improves display panels of the present utility model and showing, expectation is by the utility model, can reach the zone demonstration that produces different colours when backlight module simultaneously, and the confused situation of the background that can not cause display result takes place, to improve user's inconvenience in the use.
A purpose of the present utility model, the device of colour mixture when providing a kind of backlight module that improves display panels and showing, it mainly is a kind of back light module device that needs to show two or more colors that is applied in, this device is provided with a reflecting plate, be stacked with a light guide plate on this reflecting plate, this light guide plate one side is embedded with the light emitting diode that can produce different colours more than two, and this light guide plate is provided with recess between described light emitting diode, and the folded display panels that is provided with on this light guide plate, thus, result after the user will be measured, when pointing out with different colours light by light emitting diode respectively, can be by the obstruct of recess, and under the reflex at recess edge, what make different colours has the unlikely overlapping colour mixture of coloured light together, and when making display panels (LCD) display result, in the time of can producing regions of different colours and warn, to strengthen user's impression as the result.
Another purpose of the present utility model, the device of colour mixture when providing a kind of backlight module that improves display panels and showing, its recess machinable becomes a V-shaped breach, this breach does not run through light guide plate, or for running through the rectangular recess of light guide plate, but this groove does not laterally run through the entire backlight plate, to reduce the part assembling and to save manufacturing cost.
The technical scheme that the utility model is taked is: the device of colour mixture when a kind of backlight module that improves display panels shows is characterized in that this device includes: a reflecting plate as the usefulness of light reflection; One light guide plate, it is to be stacked on the reflecting plate, this light guide plate one side is provided with the light emitting diode more than two, described light emitting diode can be according to the coloured light that has that preestablishes display result emission different colours, and this light emitting diode keeps a determining deviation, and this light guide plate is provided with a recess between described light emitting diode, and this recess does not run through light guide plate up and down, and this recess is to be extended by the horizontal opposite side of light guide plate one side; One display panels of usefulness that is used for display digit or literal or pattern, it is stacked on the light guide plate.
Another technical scheme that the utility model is taked is: the device of colour mixture when a kind of backlight module that improves display panels shows is characterized in that this device includes: a reflecting plate as the usefulness of reflection ray; One light guide plate, it is stacked on the reflecting plate, this light guide plate one side is provided with the light emitting diode more than two, described light emitting diode can produce coloured light being arranged and keeping a determining deviation of different colours, and this light guide plate is provided with a recess between described light emitting diode, this recess is to run through light guide plate up and down, and this recess is not traverse light guide plate fully by the horizontal opposite side extension of light guide plate one side; One display panels of usefulness that is used for display digit or literal or pattern, it is to be stacked on the light guide plate.
Thus, the beneficial effects of the utility model are: the driven for emitting lights diode produces coloured light, by reflecting plate this coloured light is added strong reflection, see through the obstruct of recess and the reverse refraction at recess edge again, making describedly has the unlikely overlapping colour mixture of coloured light together, be incident upon on the background of display panels with clear, allow the user watch numeral or literal or pattern after the measurement easily, and the coloured light regional background arranged by this different colours, strengthen user's caution effect, and make whole display module more attractive in appearance.
