Description

display device

[0001] The present disclosure relates to a display device.

[0002] As the information society develops, the demand for display devices is also increasing in various forms, and in response to this, various display devices such as LCD (Liquid Crystal Display Device), PDP (Plasma Display Panel), ELD (Electro luminescent Display), and VFD (Vacuum Fluorescent Display) are being researched and used in recent years.

[0003] Among these, the LCD panel has a TFT substrate and a color substrate that face each other with a liquid crystal layer in between, and can display images using light provided from a backlight unit. In addition, the OLED panel can display images by depositing an organic layer capable of self-luminescence on a substrate on which a transparent electrode is formed.

[0004] The source PCB provides digital video data and timing control signals received from the timing controller board to the display panel. The shield can cover and protect the timing controller board and can be secured to the timing controller board and frame using screws. However, the shield's position relative to the components on the timing controller board is not fixed, requiring significant manpower to secure the screws to the shield, and the use of an automatic fastener is also problematic.

[0005] The present disclosure aims to solve the above-mentioned and other problems.

[0006] Another purpose may be to provide a structure that can minimize the movement of the shield mounted on the timing controller board prior to screw fastening.

[0007] Another objective may be to provide a shield flow minimization structure that is compatible with shields of different thicknesses.

[0008] Another purpose may be to provide various examples of flow minimization structures for shields.

[0009] According to one aspect of the present disclosure for achieving the above or other purposes, a display device may include: a display panel; a frame positioned at the rear of the display panel, to which the display panel is coupled; a board having a substrate and mounted on the frame; and a shield covering the board, wherein the board may include: an element protruding from the substrate toward the shield, the element on which the shield is mounted, and one of the substrate and the shield may include: protrusions protruding from the one to the other, penetrating the other, and spaced apart from each other.

[0010] The effects of the display device according to the present disclosure are described as follows.

[0011] According to at least one of the embodiments of the present disclosure, a structure can be provided that can minimize the flow of a shield mounted on a timing controller board before screw fastening.

Here, the thickness (tb, see Fig. 22) can be greater than the thickness (ta, see Fig. 21).

[0097] Accordingly, any one of the first guide ribs (223Rt, 223Rt') of different thicknesses can penetrate the first guide hole (123). For example, the thickness of the first guide rib (223Rt; 223Rt') can be the same as the thickness of the rib (220R; 220R') and the thickness of the body of the shield.
