Abstract

The invention relates to the technical field of liquid crystal display and discloses a vertical backlight source and a display device. The vertical backlight source comprises a back plate and a plurality of lamp tube groups arranged above the back plate; wherein each lamp tube group comprises at least one lamp tube and two connecting terminals respectively positioned at the two ends of the at least one lamp tube; each lamp tube comprises a lampshade, printing circuit bases and an LED (Light Emitting Diode) lamp, wherein the printing circuit bases are arranged on each end part of the lampshade, the LED lamp is correspondingly arranged on each printing circuit base; and each connecting terminal is connected with the printing circuit base on the corresponding side through a wire. The vertical backlight source and the display device have the following beneficial effect that the pollution of the backlight source to the environment is greatly reduced because the LED lamp tube serves as the light source.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a direct-lit backlight source and a display device. Background technique [0002] The backlight is the most important device in the display device other than the panel to determine the image quality of the display device, and its illumination effect directly determines the display image quality of the display device. With the continuous improvement of people's appreciation requirements, people's requirements for display device images are also getting higher and higher. In order to meet the needs of customers, display device manufacturers continue to improve the effect of backlight sources and develop a variety of light sources, such as: EL ( ElectroLuminescence, electroluminescence, referred to as EL), CCFL (ColdCathodeFluorescentLamp, cold cathode fluorescent lamp, referred to as CCFL), HCFL (HotCathodeFluorescentLamp, hot cathode fluorescent lamp, referred to as ...
