Description

LCD monitor having screen in both directions

The present invention relates to an LCD monitor, and more particularly, to an LCD monitor having a display unit in both directions.

In general, an LCD monitor is formed by injecting a liquid crystal between two thin polarizers to form a liquid crystal cell, and attaching an element representing a pixel to each cell to control each pixel to implement an image. Compared to the thinner and lighter than that, the use and the use of these monitors are increasing recently.

Due to the above characteristics, the LCD monitor is used as a display device of a notebook, so that the computer can be used anywhere, as well as being easily installed in a narrow space, it is widely used in various meeting places and homes.

On the other hand, when two people face each other or when a plurality of people meeting at the same place using a computer or playing a game or computer work, it is inconvenient because the same screen must be viewed together in the same position and in the same direction.

Thus, conventionally, a plurality of monitors are connected to one computer and installed in different directions, or separate large display devices are used.

However, in such a case, it is very inconvenient to install a plurality of identical monitors and to reconfigure the computer by connecting the plurality of monitors to various connection devices whenever necessary. It is also economically difficult to implement.

Therefore, the need for a display device capable of meeting and consulting each other, or playing a game and working on a computer, while watching the same screen on the display device of the computer at a time when the use of the computer is increased, such as a fortress, is increasing. will be.

The present invention has been made in accordance with the necessity as described above, the object of the present invention is to provide a monitor for LCD that a plurality of users can be viewed simultaneously in both directions by having a plurality of display units together.

In order to achieve the above object, the present invention provides a plurality of display units that stand up rear facing each other so that images can be viewed in both directions, and perform the display area by itself, and the display portions are opened to each other by a predetermined angle with respect to a rotation axis, so that a viewing angle is increased. The display unit is coupled to both sides so as to be secured and includes an inclination control unit having the rotation shaft.

When explaining the embodiment according to the present invention made as described above with reference to the drawings.

Figure 1 is a perspective view showing an embodiment according to the present invention, Figure 2 is a perspective view showing the main portion showing the state in which the inclination control unit is coupled in the embodiment, Figure 3 is a perspective view showing the assembled state of the inclination control unit cover.

As shown in FIG. 1, two display units 1 and 4 composed of a screen 2 and an outer case 3 face each other so that the screens 2 face different directions and are inclined. The display units 1 and 4 are combined with each other by the inclination adjusting unit 5 to form a monitor.

That is, the two display units 1 and 4 themselves serve as a supporting unit supporting the monitor.

The display unit in which the main PCB (not shown) is installed among the display units 1 and 4 is called a first display unit 1 and the other one is called a second display unit 4.

On the other hand, the inclination control unit 5 is coupled to the display unit (1, 4) on both sides, the combined display unit (1, 4) to maintain a predetermined angle with respect to the floor surface and the user desired The display units 1 and 4 are rotated so that the viewing angle is secured so that the inclination angle is changed.

As shown in FIG. 2, the inclination adjustment part performing the above role is a shaft 22 serving as an axis when the display units 1 and 4 rotate, and the inclination adjustment part 5 supports the shaft 22. Lower housing 23 forming a lower portion of the), two rotating brackets (21, 20) are independently installed on both sides to rotate about the shaft 22, and the side of the rotating bracket (21, 20) It is inserted into the shaft 22 so that both ends are caught in the spring (not shown) for applying torque to the rotating bracket (21, 20) has a structure similar to the hinge assembly.

Thus, the inclination control unit 5 is supported by each other by the friction force formed by the display unit (1, 4) in contact with the bottom and the bottom surface to balance the mutual force and the two display unit (1, 4) ) Spread at the same angle.

The rotating bracket coupled to the upper surface of the outer case 7 of the first display unit 1 is called the first rotating bracket 21 and coupled to the upper surface of the outer case 3 of the second display unit 4. It is referred to as the second rotating bracket 20.

In addition, the lower housing 23 is formed integrally with the lower portion of the second rotating bracket 20 so that the second rotating bracket 20 is rotated together when rotating.

Since the rotating brackets 20 and 21 are coupled to the shaft 22 and supported by the lower housing 23, the rotating brackets 20 and 21 are not rotated below the upper surface of the lower housing 23 so that the display unit 1, 4) are prevented from being folded more than necessary.

Image control from the main PCB installed in the first display unit 1 to the second display unit 4 using the inclination adjusting unit 5 that couples the two display units 1 and 4 as a connection passage. A plurality of connectors 25 for transmitting signals are connected so that the connector 25 is not exposed to the outside.

In addition, a sub PCB 24 for assisting the main PCB is installed to be connected to the connectors 25 at an upper portion of the first rotation bracket 21 of the inclination control part 5. Mediate the signal transmitted through (25) in the middle.

In addition, the connectors 25 are wires surrounded by insulators having a good circumference so that the rotating brackets 20 and 21 bend naturally as they move.

Meanwhile, as shown in FIG. 3, the rotation brackets 20 and 21 protect the inclination adjusting part 5, the connector 25, and the sub PCB 24 connected to the connector 25. Covers 30 and 31 are respectively installed at the top.

The second cover positioned above the second rotating bracket 20 has a hook catching hole 32 formed at both bottoms of both side walls, and hooks into both side walls of the lower housing integrally coupled with the second rotating bracket. 34 is formed.

Thus, when the second cover is positioned on the second rotating bracket, the hook protrusion 34 is caught by the hook catching hole 32 such that the second cover 30 covers the second rotating bracket 20. In addition to being fixed in the state, the second rotating bracket is rotated together when rotating.

In addition, an upper portion of the second cover 30 extends further from both side walls to be parallel to the second display unit 4 to cover the second bracket portion coupled with the second display unit 4 by a screw. The upper rear end of the second cover 30 opposite to the extended portion is partially cut inward and opened together with the rear of the second cover 30.

In addition, the first cover 31 is positioned so that a portion of the rear portion is introduced into the open rear portion 36 of the second cover 30 so that the first cover 31 does not interfere with the upper portion of the second cover 30 during rotation. It is located at the top of the bracket 21.

In addition, the first cover 31 has hook support protrusions 33 formed on both sides of the inner wall, and hook support portions formed on the first cover 31 positioned on both sides of the first rotating bracket 21. The hook engaging base 33 is inserted into 35 and fixed to rotate together with the first bracket 21.

As the cover 30 and 31 are coupled to the inclination control unit 5 as described above, the sub PCB 24 and the connector in the inclination control unit 5 are protected, and the first cover 31 and the second cover are protected. When the 30 is rotated, the first cover 31 enters the open portion 36 of the rear portion of the second cover 30 so that the first cover 31 does not interfere with each other and covers the inclination adjusting part 5 so as to protect from the outside at all times. The state is maintained.

On the other hand, in Figure 1, the lower end of the display unit (1, 4) supporting the display unit (1, 4) with respect to the bottom surface and the support protrusion made of an elastic body to prevent the display unit (1, 4) slipping ( 6) is additionally installed.

The base projection 6 has a circular contact with the bottom surface and has a shape similar to a thimble.

Alternatively, unlike the above, the support protrusion 6 may be formed long along the lower surfaces of the display units 1 and 4.

On the other hand, the support protrusions 6 installed in each of the display units 1 and 4 have different coefficients of friction with respect to the bottom surface by varying their materials or shapes, thereby inclining the inclination angles of the display units 1 and 4. The adjustment can be made easily.

That is, when an external force is applied to the first display unit 1 or the second display unit 4, the display unit having the support projection having a larger friction coefficient value is relatively less pushed than other display units, and thus is fixed. The display unit provided with the support protrusion having a small friction coefficient value is slid with respect to the bottom surface to adjust the inclination angle of the display unit.

Referring to the operation of the embodiment configured as described above is as follows.

The display unit itself has two display units coupled to both sides by one member of the inclination adjusting unit so that the display unit itself is supported so that the display unit is erected to a desired viewing angle without a separate support device for supporting the display unit itself. Do this.

In addition, only one inclination adjusting unit installed between the display units is configured to distribute the force between the two display units, thereby maintaining a stable viewing angle of the monitor.

As described above, the present invention can manufacture an LCD monitor having a plurality of display parts facing in both directions, but the structure is not complicated and has a stable support structure, and the friction torque is expensive for adjusting the viewing angle desired by the user. There is an advantage that the LCD monitor can be easily set to the desired tilt without using a large hinge.

In particular, since there is no need for a support unit separately required to equip the plurality of display units together, there is an economic effect that the production cost is reduced and parts are reduced, thereby improving production efficiency.

In addition, since the existing LCD display unit may be utilized as it is, the cost of additional costs in producing a new product may be reduced by configuring the monitor having a plurality of display units.
