Description
Technical field
The present invention relates to technical field of LED display, more particularly to a kind of LED transparent display screens structure and its manufacture method.
Background technology
Since 2000, China LED shows application industry stable development, and total size rises year by year, at present into
For the important component in LED industry chain, the LED using LED display as representative shows that application product is each in social economy
Field is widely applied, and LED shows the emerging production that application industry has become advantage and characteristic is obvious, development is thriving
Industry.
With the driving of application market, LED transparent display screens become the hot spot studied at present, and with wide
Application scenarios.As LED transparent display screens can be applied to display and demonstration, airport, advertisement media, chain sales field, megastore, enterprise
The places such as industry exhibition room, museum, science and technology center, make interesting changeable equipment for production marketing and advertising and support, allow advertisement
Intention attacks actual product directly, as long as the place for having glass curtain wall can apply.
But patch is welded in one after LED transparent display screens traditional at present are each encapsulated using side-emitting led lamp with driving IC
Method in block PCB substrate is made, and Fig. 1 is illustrated that the schematic perspective view of traditional LED transparent display screens structure 100, from
See on the whole, traditional LED transparent display screens structure 100 is similar to micro book shelf structure, mainly by display frame 101 and PCB
Display board 102 is formed, and is engraved structure between display frame 101 and PCB display boards 102.
Fig. 2A and Fig. 2 B are the concrete structure diagram of the PCB display boards 102 of tradition LED transparent display screens structure 100, wherein
Fig. 2A be PCB display boards 102 schematic cross-section, Fig. 2 B be PCB display boards 102 top view, PCB display boards 102 mainly by
PCB substrate 1021, side-emitting led lamp 1022 and LED drive chip 1023 form.In the typical design, when a line picture
When plain spacing is P, the spacing of row pixel is 4P, so as to fulfill the LED transparent display screens structure 100 carry out graphical display when,
Display content can be slightly watched on the outside of display screen at a distance, but the scene of outside can be watched on the inside of display screen；At the same time when the LED is saturating
When bright display screen structure 100 is without graphical display, the interior outside of display screen can see the scene on opposite clearly, and this screen is in industry
Inside also it is called curtain screen.
Patch is welded in PCB substrate after independently being encapsulated due to side-emitting led lamp 1022 and LED drive chip 1023
On 1021 (as shown in Figure 2 B), PCB substrate 1021 needs have certain width, generally between 8mm-15mm, ordinary circumstance
Under, row pel spacing P is smaller, then the width of PCB substrate 1021 is wider.The thickness of PCB display boards 102 after encapsulating at the same time
Typically about 2mm or so.There are two main problems for tradition LED transparent display screens structure 100：
One is translucency is bad, translucent effect is with angle change, and when picture element density is higher, its light-transmission angles
It is smaller, therefore the technical requirements of P 2.5 (pel spacing 2.5mm) below difficult to realize.Traditional LED transparent display screens structure
The principle schematic of the 100 existing problems is as shown in Figure 3.The side view of traditional LED transparent display screens structure 100 shown in Fig. 3
Figure, when the width of PCB display boards 102 is L, thickness is D, we carry out hypothesis below, according to current driving chip and side
The specification of the emitting led grade in face, as row pel spacing P=3.5mm, its row pel spacing is generally M=4P, i.e. M=14mm is left
The right side, it is corresponding when the width of PCB display boards 102 is L=12mm, thickness D=2mm, so as shown in Figure 3 as can be seen that should
Between the printing opacity limit of display screen is+45 ° to -45 °.It can be seen from the above that when row pel spacing P smallers, the model of its light-transmission angles
Enclose smaller, so as to cause the transparent effect of transparent screen very poor.
The second is the problem of above-mentioned traditional LED transparent display screens structure 100 is due to size and material, causes its weight
It is very heavy, it is unfavorable for installing, the assembling of outdoor screen especially high-rise to large area is more unfavorable.
Therefore, a kind of new LED transparent display screens structure and its manufacture method are needed, is solved at least in part above-mentioned existing
It is the problems such as below 2.5mm and weight are heavy that translucency present in technology is poor, can not accomplish pel spacing.
