Description

Display device {DISPLAYING APPARATUS}

The present invention relates to a display apparatus, and more particularly, to a display apparatus having an improved structure of an ear for distributing a load of a display unit.

A display device is a general term for a TV or a computer monitor, and is generally classified into an LCD monitor and a CRT monitor.

CRT monitor uses cathode ray tube to emit different brightness or color by hitting monochromatic or RGB (Red, Green, Blue) fluorescent material coated on the surface of CRT according to the intensity of video signal. It uses the principle of making, which is widely used because it is the most economical and excellent in terms of price and performance, but has the disadvantage of being bulky.

On the other hand, LCD monitor uses the principle that the liquid crystal (liquid crystal crystal) disperses the molecular arrangement of the liquid crystal and prevents light from passing through it. It has the advantage of making the monitor thin, but it is more expensive than the CRT monitor. There is a disadvantage of poor performance.

In the above classification, the idea of the present invention will be described using an example of a display device having a cathode ray tube as described below.

As shown in FIG. 1, the conventional display apparatus 100 includes a display unit 110 for forming an image, a PCB assembly (not shown) for transmitting an image signal to the display unit 110, and a display unit ( 110) and a casing for receiving and supporting the PCB assembly.

The display unit 110 and the cathode ray tube bulb 111 formed by the combination of the panel 112, the funnel-shaped funnel 113 and the neck (not shown) to be coupled to the rear of the panel 112, the image is formed; And an electron gun unit (not shown) inserted into the neck of the cathode ray tube bulb 111 to generate an electron beam into the cathode ray tube bulb 111.

In each corner region of the display unit 110, an ear 114 having a protruding boss fastening hole 115 on a plate surface fastened by the protruding boss 123 and the second screw 132 of the front casing 121 will be described later. The display 110 is fixedly supported by the front casing 121.

The PCB assembly is fixed to the bottom of the casing by a screw (not shown) or the like, and is electrically connected to the electron gun unit to transmit a predetermined image signal to the electron gun unit. Accordingly, when different amounts of electron beams are projected into the cathode ray tube bulb 111 from the electron gun unit according to the intensity of the image signal, the electron beams are monochromatic or RGB (Red, Green, Blue) fluorescent materials coated on the surface of the panel 112. By hitting the light to form light of different brightness or color, the image is formed on the display 110.

The casing 20 is disposed in front of the display 110 and is coupled to the front casing 121 for blocking the front edge of the display 110 and the rear of the front casing 121 to display the display 110 and the PCB. It has a back casing 122 for receiving the assembly. On the back of the front casing 121, the screw coupling portion 128 is provided to fasten the first screw 131 passing through the screw coupling hole 127 provided in the rear casing 122, and the front casing 121 and The rear casing 122 is coupled to accommodate the display unit 110 and the PCB assembly.

Each of the corner regions of the rear surface of the front casing 121 protrudes toward the rear casing 122, and a plurality of protrusion bosses having screw fastening portions 124 to which a screw thread is formed to fasten the second screw 132 ( 123). In addition, the protrusion bosses 123 are interconnected by the support ribs 125. Accordingly, when the display unit 110 is mounted on the front casing 121, the second screw 143 passing through the protruding boss fastening hole 115 of the ear 114 provided at each corner of the display unit 110 is provided. By being fastened to the protruding boss 123 provided at each corner region of the front casing 121, the load of the display 110 is transmitted to and supported by the protruding boss 123 through the ear 114.

In particular, some of the protruding bosses 123 are provided to support the lower surface of the display 110 when the display 110 is installed in the front casing 121. As a result, the load of the display 110 is prevented from being concentrated on the protruding boss 123 fastened to the ear 114, thereby preventing the appearance of the front casing 121 from being deformed by the load of the display 110. Done.

However, in the conventional display apparatus 100, the size of the casing 120 is increased by the protruding boss 123 and the support rib 125 for supporting the load acting on the lower surface of the display unit 110. Overall, there is a disadvantage in that the size of the display apparatus 100 is increased.

In addition, in the case of the display apparatus 100 ("combined display apparatus") in which the display apparatus 100 and the imaging apparatus such as a VTR, DVD, etc. are integrally manufactured, such an imaging apparatus is disposed below the display unit 110. It is common to be deployed.

Therefore, in order to secure the installation space of the imaging device in the lower region of the front casing 121, it is necessary to remove the protruding boss 123 and the support rib 125 in the lower region of the front casing 121, in this case, the display unit 110 ) Is concentrated on the ear 114 and the protruding boss 123 coupled thereto, causing a deformation of the outer casing 121.

Accordingly, it is an object of the present invention to provide a display device capable of distributing and supporting a load of a display unit while securing an installation space of a video device.
