The present invention has been devised in view of the above-described circumstances, and it is easy to maintain and repair the monitor by providing various information to the passengers more clearly using the LCD monitor. The purpose is to provide an LCD monitor for railroad cars that can be used.

The present invention for achieving the object described above, the monitor body is formed in a cylindrical shape made of steel and its front and rear surfaces are inclined inwardly by a predetermined angle while descending from the top to the bottom to have an inverted triangle cross section. And fixing brackets which are respectively installed on the left and right sides of the upper end of the monitor body so as to fix the monitor body to the inner ceiling of the railway vehicle, and a coil spring having a cushioning force on the outer circumferential surface thereof, and on the front and rear surfaces of the monitor body, respectively. A pair of LCD screens are provided, and a display unit capable of displaying various types of information through the LCD screen, and a plurality of speakers are provided on either side of the monitor body, and a fan and a plurality of heat sinks are provided for heat dissipation of the monitor body. The speaker plate is provided with a heat dissipation hole.

The display unit is rotatably coupled by a plurality of hinges on the upper portion of the monitor body, and the lower end of the display unit is coupled to the monitor body by fastening means so that the display unit can be opened and closed by rotating the display unit.

That is, the LCD monitor having the above structure is formed to be inclined with the front / rear side facing inward, so that the display portion of the LCD monitor can provide an image through the screen at an inclined angle, and the display portion is the monitor body. It is installed to be rotatable about to open and close the monitor body.

Therefore, the LCD monitor can provide various types of information to passengers inside the railroad car with clearer picture quality, and the LCD monitor provides an image in an inclined state, thereby eliminating inconvenience caused by reflection of the screen. In addition, since the monitor body can be easily opened and closed, the maintenance and repair work of the LCD monitor can be facilitated, and the external aesthetics of the LCD monitor can be improved to improve the atmosphere inside the railroad car, thereby providing more convenience to the passenger.
