Description
Technical field
The utility model belongs to the sub-display screen technology field of LED electrical, relates to a kind of indoor dual base color display screen, particularly relates to a kind of indoor Φ 3.0 dual base color display screen.
Background technology
Indoor dual base color display screen, especially indoor Φ 3.0 dual base color display screen (that is, the diameter of LED lamp bead is the indoor dual base color display screen of 3.0mm) becomes now and has become more and more popular.But the LED mode of existing indoor Φ 3.0 dual base color display screen is lattice module, and the welding of lattice module is generally immersed solder, and like this, its flatness is stricter to artificial requirement.Meanwhile, two luminous point is encapsulated in a LED lamp bead respectively, like this, the well-balanced property of its luminescence and consistance poor.
Existing indoor Φ 3.0 dual base color display screen has following shortcoming: be 1, immersed solder due to what be that welding adopts, therefore, need change whole module when single-point is bad, and maintenance is inconvenient and easily cause waste.2, its flatness is low, stricter to artificial requirement.3, it is pixel light intensity module, brightness irregularities.
In view of the above-mentioned technological deficiency of prior art, in the urgent need to developing a kind of novel indoor dual base color display screen.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existed in prior art, provides a kind of indoor dual base color display screen, and it can improve well-balanced property and the consistance of pixel luminescence, makes display screen more well-balanced on color; Meanwhile, plug-in unit man-hour can be reduced, improve flatness, fast easy to maintenance.
To achieve these goals, the utility model provides following technical scheme: a kind of indoor dual base color display screen, it is made up of multiple identical display module, each described display module comprises a printed circuit board (PCB), it is characterized in that, described printed circuit board (PCB) there are multiple identical LED LED lamp bead and amplifying circuit, driving circuit and line control circuit by Placement, described LED LED lamp bead is the LED LED lamp bead of two-in-one encapsulation, is packaged with an emitting red light point and a green emitting point in it.
Further, wherein, the diameter of described LED LED lamp bead is 3.0mm.
Compared with existing indoor dual base color display screen, indoor dual base color display screen of the present utility model has following Advantageous Effects:
1, each LED LED lamp bead is the LED LED lamp bead of two-in-one encapsulation, like this, produces and greatly will shorten plug-in unit man-hour, improve production efficiency.
2, color-division is easy, saturation degree is high, thus improves well-balanced property and the consistance of each pixel luminescence, makes display screen more well-balanced on overall color.
3, mount with chip mounter, when single pixel breaks down, contribute to keeping in repair single trouble spot, make it easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of indoor dual base color display screen of the present utility model.
Fig. 2 is the structural representation of display module.
Embodiment
Further illustrate the utility model below in conjunction with drawings and Examples, the content of embodiment is not as the restriction to protection domain of the present utility model.
Fig. 1 shows the structural representation of indoor dual base color display screen of the present utility model.See Fig. 1, similar with existing indoor dual base color display screen, indoor dual base color display screen of the present utility model is also linked together by the identical display module A of multiple structure and forms.Each display module A formed indoor dual base color display screen that links together can show our picture to be expressed and content.
Unlike the prior art, in the utility model, described display module A comprises printed circuit board (PCB) 1.Described printed circuit board (PCB) 1 there is multiple identical LED LED lamp bead 2 by Placement.Wherein, described LED LED lamp bead 2 is the LED LED lamp bead of two-in-one encapsulation, is packaged with an emitting red light point and a green emitting point in it.
Therefore, the diode of two kinds of different colours (being respectively red pipe and green pipe) is different as a pixel from adopting in prior art, in the utility model, adopt the LED LED lamp bead 2 of two-in-one encapsulation, namely red, green two luminous points are encapsulated in same LED LED lamp bead 2 li.Like this, its color-division is easy, saturation degree is high, thus improves well-balanced property and the consistance of each pixel luminescence, makes display screen more well-balanced on overall color.
Meanwhile, to carry out plug-in unit in prior art different, in the utility model, described LED LED lamp bead 2 is mounted on described printed circuit board (PCB) 1 by paster technique.Particularly, first brushing tin cream on described printed circuit board (PCB) 1, then make to be coated be brushed with tin cream printed circuit board (PCB) 1 through chip mounter, by chip mounter, described LED LED lamp bead 2 is affixed on described printed circuit board (PCB) 1 according to the position set.Cross Reflow Soldering after this operation completes, tin cream melts, together with being sticked in LED LED lamp bead 2 by printed circuit board (PCB) 1.Like this, each LED LED lamp bead 2 is only a surface-mounted device, therefore, produces and greatly will shorten plug-in unit man-hour, enhance productivity.
Meanwhile, as shown in Figure 2, described printed circuit board (PCB) 1 also there are amplifying circuit 3, driving circuit 4 and line control circuit 5 by Placement.Similarly to the prior art, described amplifying circuit 3, driving circuit 4 and line control circuit 5 can be mounted on described printed circuit board (PCB) 1 by paster technique.Wherein, described amplifying circuit 3, driving circuit 4 and line control circuit 5 and amplifying circuit of the prior art, driving circuit are identical with the 26S Proteasome Structure and Function of line control circuit, do not describe in detail at this.
In use, the signal from outside is sent to described driving circuit 4 and line control circuit 5 after described amplifying circuit 3 amplification process.Wherein, described driving circuit 4 and line control circuit 5 are used for driving and controlling described LED LED lamp bead 2, make described LED LED lamp bead 2 send the color and brightness wanting to reach.Each like this display module A formed indoor dual base color display screen that links together just can show our picture to be expressed and content.
Finally, in the utility model, preferably, the diameter of described LED LED lamp bead is 3.0mm.Like this, described indoor dual base color display screen just becomes conventional indoor Φ 3.0 dual base color display screen.
Above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to the technical solution of the utility model the apparent change of extending out or variation be still in the row of protection domain of the present utility model.
