Liquid crystal display device, configurational structure of front frame and middle frame thereof

摘要

The present invention discloses a configuration structure for a front frame and a middle frame for use in a liquid crystal display device, and includes a front frame including a sidewall with a first tab and a first notch alternatively arranged. A middle frame is arranged with respect to the front frame, and includes a sidewall having a second notch corresponding to the first tab, and a second tab corresponding to the first notch, alternatively arranged; and wherein the first tab engages with the second notch, and the second tab engages with the first notch so as to securely interlock the front frame and the middle frame. The thickness made up by the sidewall of the front frame and the gap between the front frame and the middle frame is properly reduced, and this can effectively benefit the narrow-border of the liquid crystal display device. In addition, since the backboard is still there without being compromised, the overall mechanic strength of the liquid crystal display is greatly enhanced. On the other hand, since the sidewall of the front frame is directly in connection with the sidewall of the backboard on which the light source is mounted, the front frame can be properly served as a heatsink so as to improve the overall heat dissipation of the liquid crystal display device. The present invention further provides a liquid crystal display device incorporated with such a configurational structure.

主权项

1. A configurational structure of a front frame and a middle frame for use with a liquid crystal display device, including
a front frame including a sidewall with a first tab and a first notch alternatively arranged, the sidewall having a proximal end fixed to the front frame and an opposite distal end that is free and is not supported; a middle frame arranged with respect to the front frame, and including a sidewall having a second notch corresponding to the first tab, and a second tab corresponding to the first notch, alternatively arranged; and wherein the first tab comprises two opposite and substantially parallel side edges and the first notch is delimited between two opposite and substantially parallel walls and has an entry opening formed in the distal end of the sidewall of the front frame; wherein the second tab comprises two opposite and substantially parallel side edges respectively corresponding to the walls of the first notch and the second notch is delimited between two opposite and substantially parallel walls respectively corresponding to the side edges of the first tabs; and wherein the first tab is received in and engages with the second notch, and the second tab is received through the entry opening into the first notch and engages with the first notch so as to securely interlock the front frame and the middle frame, wherein an outside surface of the first tab is substantially flush with an outside surface of the second tab.
