Abstract

An LCD structure with excellent heat dissipation efficiency is disclosed. The LCD structure has a display body comprising a front cover framed onto the front side of the display body; a rear cover framed onto the rear side of the display body, and the rear cover is mounted to the front cover to form a cavity to hold circuit board and electronic components, and the rear side surface of the rear cover has a through hole in communication with the cavity; and a rear panel, wherein a plurality of protruded pillars are formed between the edge of one side face of the rear panel and the through hole surrounding on the rear cover, the protruded pillar provide a distance for the rear panel to be mounted beyond the through hole of the rear cover so that a plurality of sideway dissipation holes are formed in between individual protruded pillars to the cavity.

Claims

1. A LCD structure with excellent heat dissipation efficiency having a display body hinged onto a seat body allowing the display body to be adjusted at an appropriate angle, wherein the display body includes

a front cover framed onto the front side of the display body;

a rear cover framed onto the rear side of the display body, and the rear cover is mounted to the front cover to form a cavity to hold circuit board and electronic components, and the rear side surface of the rear cover has a through hole in communication with the cavity; and

a rear panel, wherein a plurality of protruded pillars are formed between the edge of one side face of the rear panel and the through hole surrounding on the rear cover, the protruded pillar provide a distance for the rear panel to be mounted beyond the through hole of the rear cover so that a plurality of sideway dissipation holes are formed in between individual protruded pillars to the cavity.

2. The LCD structure of claim 1, wherein around the surrounding of the through holes of the rear cover, a plurality of combination holes are provided, and the individual protruded pillar is installed with combination pillar mounted onto the combination hole having a smaller diameter as compared to that of the protruded pillar.

3. The LCD structure of claim 1, wherein the combination protruded pillar exposed at the inner side of the combination hole is fused on to the rear cover.

4. The LCD structure of claim 1, wherein beyond the side face of the rear cover is a pivotal slot, and the sides of the pivot slot are respectively provided with a pivot seat and the two pivot seats are individually mounted with a chain extended to the pivot slot, and the chain has a plurality of screw holes, and the seat body has a securing slot for the engagement of the chain and the bottom side of the securing slot has a plurality of through hole to the bottom section thereof, and the through hole is for screws to pass through.

5. The LCD structure of claim 1, wherein the rear panel is provided with a plurality of through holes for the passing through the connector within the cavity for the connection of the connection wire for signal or power source.

6. The LCD structure of claim 1, wherein the rear panel is provided with a plurality of heat dissipation holes through the rear panel arranged in rows.

7. The LCD structure of claim 1, wherein the seat body includes

a securing plate being a horizontal plate body having one end pivotally mounted on the rear cover so that the display body swings at an appropriate angle on the seat body,

a support plate being a plate body mounted below the securing plate and parallel to the securing plate;

and

a connection plate being an arch-shaped plate body having an upper edge connected to one side edge of the securing plate, and having a lower edge connected at one edge of the support plate such that the seat body formed into a U-shaped structure.

8. The LCD structure of claim 7, wherein the bottom section of the side face of the rear is a pivot slot having a protruded pivot seat at each of the two sides of the slot, and the two pivot seat are provided with a chain extended to the pivot slot, and the chain has a plurality of screw holes, and the seat body has a securing slot for the engagement of the chain and the bottom side of the securing slot has a plurality of through hole to the bottom section thereof, and the through hole is for screws to pass through.

9. The LCD structure of claim 8, wherein the support plate has a slot hole allowing a tool to be inserted to tighten a screw to the through hole.
