Abstract

The invention discloses a backlight module and a liquid crystal display. The backlight module comprises a front plastic frame, a rubber frame, a chip component and an electromagnetic shielding part, wherein the chip component is arranged between the front plastic frame and the rubber frame; the electromagnetic shielding part is arranged around the chip component and used for isolating the interference of external electromagnetism to the chip component. When the front frame of the backlight module is made of plastics, the interference of the external electromagnetism to the chip component can be prevented through the electromagnetic shielding part, so that the stability of a control signal of the chip component is ensured, and furthermore, the picture display quality is ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal display. 【Background technique】 [0002] With the continuous development of liquid crystal technology, the requirements for various components in the liquid crystal display are getting higher and higher. [0003] Take the backlight module as an example, please refer to figure 1 , figure 1 It is a structural schematic diagram of a backlight module in the prior art.
