Embodiment Construction

[0018] refer to figure 1 , the plasma display device includes a plasma display panel 10 (PDP), a chassis 20 , a circuit board 30 , and at least one main fastening unit 40 . In addition, the front case 1 and the rear case 2 are respectively connected on the front side and the rear side of the plasma display module constituted by sequentially coupling the plasma display panel 10, the chassis 20 and the circuit board.

[0019] The PDP 10 displays desired images by plasma discharge. The bottom plate 20 has a first surface fixed to the rear surface of the PDP 10 to support the PDP 10 . The circuit board 30 is disposed on a second surface opposite to the first surface in the bottom plate 20 to drive the PDP 10 .

[0020] The main fastening unit 40 fixes the circuit board 30 to the bottom plate 20 ( figure 2 shown in ). The circuit board 30 is spaced apart from the base plate 20 to prevent the electronic components of the circuit board 30 from short circuiting when they contact ...

Abstract

A display device which has a simplified assembly process and minimized product damage. The display device includes a display panel (10); a chassis base (20) having a first surface for supporting and for fixing the display panel thereto; a circuit board (30) fixed to a second surface of the chassis base, the circuit board (30) having circuit elements for driving the display panel; and at least one main fastening unit (40) for fixing the circuit board to the chassis base such that a gap is formed between the circuit board (30) and the chassis base (20). The main fastening (40) unit includes a main body, fasteners, and first and second protrusions to form engaged portions. The display device may be a plasma display device.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to a plasma display device capable of easily fastening a circuit board. Background technique [0002] Recently, various types of display devices, for example, plasma display devices, have been researched and developed. In general, plasma display devices utilize plasma discharges to achieve desired images. [0003] Such a plasma display device includes a plasma display panel (PDP) on which desired images are displayed by supplying power to the PDP. The device also includes: a chassis to support the PDP on a front surface thereof; and a circuit board mounted on a rear surface of the chassis to drive the PDP. [0004] In some cases, the front case and the rear case are connected to the front and rear of the plasma display module, respectively. Also, the front case has an opening so that a user can see an image output from the PDP. [0005] To assemble a plasma display device, th...
