Problems solved by technology

[0004] However, since the current grounding technology needs to use additional conductive components, the cost of the module will increase, especially the price of metal shrapnel and metal conductive cloth is not low
In addition, although the method of locking screws does not increase the cost much, since the screws need to be locked on the pri

Abstract

The invention discloses an LCD (liquid-crystal display) at least including a backlight module, a light source group, a rubber frame, an LCD panel module and a PCB (printed-circuit board). The backlight module at least includes a metal back plate, wherein the metal back plate at least includes a bottom plate and a side plate; the light source group is arranged in the metal back plate; the rubber frame is arranged on the outer edge of the metal back plate and attached to the outer side surface of the side plate of the metal back plate, wherein the rubber frame at least include a spring pressingpiece; the LCD panel module is arranged on the backlight module; and the PCB is electrically connected with the LCD panel module and arranged on the outer side of the backlight module, wherein the PCB at least includes a grounding area, and the spring pressing piece correspondingly presses the PCB for enabling the grounding area to be in direct contact with the metal back plate.

Description

technical field [0001] The present invention relates to a flat display device, and more particularly to a liquid crystal display (LCD). Background technique [0002] The design of the current liquid crystal display module (LCD Module) is developing toward high resolution. In the case of pursuing high resolution, the layout of the printed circuit board (PCB) becomes more and more complicated, so the requirements for the protection of modules against electromagnetic interference (EMI) are also increasingly stringent. [0003] Generally speaking, a good grounding of the module is an effective way to solve electromagnetic wave interference. The commonly used grounding technologies currently use additional components, such as screws, metal shrapnel or metal conductive cloth (Gasket), as an electrical conduction medium between the printed circuit board and the front frame or backplane, thereby making the printed circuit board The circuit board is grounded through the backplane a...
