Abstract

A thin LCD device includes an LCD panel with fixing holes; a fixed plate with two opposite sides covering two opposite sides of the LCD panel and having through holes corresponsive to the fixing holes of the LCD panel respectively; a main board fixed to the fixed plate and the fixed plate being installed between the main board and the LCD panel; a housing shielding the main board and covering sides of the LCD panel and the fixed plate and having through holes corresponsive to the through holes of the fixed plate and the fixing holes of the LCD panel; and a fixing element passing through the respective through hole of the housing, the respective through hole of the fixed plate and the respective fixing hole of the LCD panel to fix the housing, the fixed plate and the LCD panel, so as to facilitate assembling and reduce thickness.

Claims

1. A thin LCD device, comprising:

an LCD panel, having a plurality of fixing holes formed on two opposite sides of the LCD panel respectively;

a fixed plate, with two opposite sides covering the two opposite sides of the LCD panel respectively, and the two opposite sides of the fixed plate having a plurality of through holes formed thereon, and each through hole being configured to be corresponsive to each respective fixing hole of the LCD panel;

a main board, fixed to the fixed plate, and the fixed plate being installed between the main board and the LCD panel;

a housing, shielding the main board, and covering each side of the LCD panel and the fixed plate, and the housing having a plurality of through holes formed on two opposite sides of the housing respectively, and each through hole being configured to be corresponsive to each respective through hole of the fixed plate and each respective fixing hole of the LCD panel; and

a plurality of fixing elements, passing through the through holes of the housing, the through holes of the fixed plate, and the fixing holes of the LCD panel sequentially and respectively to fix the housing, the fixed plate and the LCD panel.

2. The thin LCD device of claim 1, further comprising two side fixing strips installed between the housing and the fixed plate, and the side fixing strips having a plurality of through holes, and each through hole being configured to be corresponsive to each respective through hole of the fixed plate, and each respective fixing hole of the LCD panel, wherein the fixing elements are passed through the through holes of the housing, the through holes of the fixing strips, the through holes of the fixed plate, and the fixing holes of the LCD panel sequentially and respectively to fix the housing, the side fixing strips, the fixed plate and the LCD panel.

3. The thin LCD device of claim 1, wherein the fixed plate is disposed close to the LCD panel.

4. The thin LCD device of claim 3, further comprising two side fixing strips installed between the housing and the fixed plate, and the side fixing strips having a plurality of through holes, and each through hole being configured to be corresponsive to each respective through hole of the fixed plate, and each respective fixing hole of the LCD panel, wherein the fixing elements are passed through the through holes of the housing, the through holes of the fixing strips, the through holes of the fixed plate, and the fixing holes of the LCD panel sequentially and respectively to fix the housing, the side fixing strips, the fixed plate and the LCD panel.

5. The thin LCD device of claim 3, wherein the housing is disposed close to the main board.

6. The thin LCD device of claim 5, further comprising two side fixing strips installed between the housing and the fixed plate, and the side fixing strips having a plurality of through holes, and each through hole being configured to be corresponsive to each respective through hole of the fixed plate, and each respective fixing hole of the LCD panel, wherein the fixing elements are passed through the through holes of the housing, the through holes of the fixing strips, the through holes of the fixed plate, and the fixing holes of the LCD panel sequentially and respectively to fix the housing, the side fixing strips, the fixed plate and the LCD panel.

7. The thin LCD device of claim 1, wherein the housing is disposed close to the main board.

8. The thin LCD device of claim 7, further comprising two side fixing strips installed between the housing and the fixed plate, and the side fixing strips having a plurality of through holes, and each through hole being configured to be corresponsive to each respective through hole of the fixed plate, and each respective fixing hole of the LCD panel, wherein the fixing elements are passed through the through holes of the housing, the through holes of the fixing strips, the through holes of the fixed plate, and the fixing holes of the LCD panel sequentially and respectively to fix the housing, the side fixing strips, the fixed plate and the LCD panel.
