Description

Display Device {Display Device}

The present disclosure relates to a display device, and more specifically, to a display device in which a voltage drop of power supplied to a plurality of display panels does not occur and thus the display panel can be easily expanded.

In general, a display device is a device that receives and displays video signals and is installed on TVs, monitors, billboards, smart phones, etc., and as a means of displaying images, organic light emitting displays (OLEDs) and liquid crystal displays are used. A variety of devices are used, such as (LCD: Liquid Crystal Display Device) and plasma display (PDP: Plasma Display Panel).

Recently, as the information society develops, the demand for display devices is changing in various forms, and they are gradually becoming lighter, larger, and slimmer. In addition, the demand for flexible display devices that can change their appearance to suit various uses and environments such as buildings, interiors, and exhibitions is increasing.

A flexible display device may be implemented by arranging a plurality of LED elements on one or both sides of a film-type substrate made of transparent or opaque material and producing an image according to the emission of light from each LED element.

In the case of a large-screen display device, it is difficult to implement it with a single integrated display panel, so a display panel of a certain size is composed of unit blocks, and a plurality of unit display panels are connected to implement a large-screen display device. Since a large-screen display device must supply direct current power to each unit display panel, the converted direct current power from a switched-mode power supply (SMPS) located at the top or bottom of the display device is supplied to the display modules. .

In such prior art large screen display devices, it was inevitable to use multiple electric cables to supply direct current power to each of the multiple unit display panels. That is, the large screen display device had a connection structure in which each of a plurality of electric cables was connected from one switch mode power supply to each of a plurality of unit display panels.

However, as large-screen display devices with a one-to-many connection structure grow in size, the number of unit displays increases, and as the arrangement of multiple electric cables connected to one switch mode power supply becomes very complicated, the work of connecting electric cables and cables becomes more complex. A large amount of manpower was consumed in the cleanup work.

Moreover, due to the complex connection structure of multiple electric cables, the ratio of the internal space occupied by the display device increases, which is a problem that interferes with replacement or repair of internal components.

Therefore, in the prior art, a connection structure using a bus bar instead of an electric cable was applied to solve the complexity of the connection structure. Figure 1 is a front view schematically showing a display device 10 according to the prior art. And FIG. 2 is a partially exploded perspective view schematically showing some components of the display device 10 according to the prior art.

1 and 2, the display device 10 according to the prior art includes a plurality of display panels 11: 11-1, 11-2, 11-3, 11-4, 11-5, and 11-6. , 11-7, 11-8, 11-9, 11-10, 11-11, 11-12, 11-13, 11-14, 11-15, 11-16, 11-17, 11-18, 11 -19, 11-20), a plurality of control modules (12: 12-1, 12-2, 12-3) combined with connectors (not shown) provided on the display panel 11, these control modules ( 12) included a switch mode power supply 13 configured to supply direct current power, and bus bars 14: 14-1, 14-2, 14-3.

In the prior art, a bus bar made of copper alloy was used for the electrical connection between the control module 12-1 and another control module 12-2 and the electrical connection between the control module 12 and the switch mode power supply 13. At this time, the connection between the bus bar 14-1 and the other bus bar 14-2 and between the bus bars 14-1, 14-2, and 14-3 and the control module 12 were fastened with bolts. However, when multiple control modules (12-1, 12-2, 12-3) are included, it is difficult to place them in the internal space because a rigid bus bar (14) is used, resulting in poor space utilization and multiple bus bars. A lot of work time was required to fasten the bolts between (14-1, 14-2, 14-3).

In addition, this bolt fastening was prone to creating gaps in the mating surface between the bus bar 14-1 and the other bus bar 14-2. Gaps between these bolted bus bars 14-1, 14-2, and 14-3 cause high electrical resistance, and the high electrical resistance causes a voltage drop, resulting in failure of the display device 10. This could happen. In this way, a lot of attention and difficulty was involved in fastening the bolts between the plurality of bus bars (14-1, 14-2, and 14-3).

Moreover, since the bus bar 14 has a certain electrical resistance (specific resistance), as shown in FIG. 2, even in the case of the bus bar 14 with excellent electrical conductivity, a voltage drop occurs when a direct current flows, When the bolt connection between the bus bar (14-1) and the other bus bar (14-2) becomes loose due to an external impact, a large electrical resistance occurs at the joint area, which is likely to cause a large voltage drop. For this reason, when direct current power is supplied from the bottom to the top through a large number of bus bars 14 to supply power to a plurality of display panels 11-1, ... 11-20, the bus located at the top A large voltage drop occurred in the bar 14-1, making it impossible to supply power with an appropriate level of voltage to the display panel 11. The display device 10 of the prior art had great limitations in expanding the number of display panels 11, making it difficult to implement a large-sized display device.

That is, the bottom of the two connection brackets 186-3 and 186-4 is bolted to the top of the fixing bar 180, and the top of the connection bracket 186 is bolted to the ceiling S. .

Therefore, the display device 100 of the present disclosure further includes a connection bracket 186, so that the fixing bar 180 can be stably positioned and fixed to the building, and even if the fixing bar 180 receives a strong external impact, it can be protected from shock. By delivering it to the building, the DC power supply module 140 and control module 130 can be safely protected.

Meanwhile, referring again to FIGS. 3 and 4, the display device 100 of the present disclosure may further include a cover member 188. The cover member 188 may be configured to cover the control module 130 and the DC power supply module 140. The cover member 188 may be configured to be detachable from the fixing bar 180. For example, if a failure of the control module 130 and the DC power supply module 140 occurs, the cover member 188 can be separated from the fixing bar 180.

Accordingly, the display device 100 of the present disclosure further includes a cover member 188 configured to be detachable from the fixing bar 180, so that when a defect or failure of the display device 100 occurs, the DC power supply module 140 The DC power supply module 140 and the control module 130 can be easily repaired by separating only the cover member 188 from the fixing bar 180 without dismantling the fixing bar 180 that secures the control module 130. There are benefits to this.

Although the embodiments have been described with limited drawings as described above, those skilled in the art can apply various technical modifications and variations based on the above. For example, the described techniques are performed in a different order than the described method, and/or components of the described system, structure, device, circuit, etc. are combined or combined in a different form than the described method, or other components are used. Alternatively, appropriate results may be achieved even if substituted or substituted by an equivalent.

Therefore, other implementations, other embodiments, and equivalents of the claims also fall within the scope of the claims described below.
