Abstract

The invention discloses an LED light source back light module and a display device. The LED light source back light module comprises a circuit board, at least one LED light and lenses corresponding to the LED lights one by one and covering the LED lights arranged on the circuit board; the LED light source back light module further comprises a light conversion medium layer for converting monochromatic light generated by the LED lights into white light, and the light conversion medium layer is located between the lenses and the circuit board and arranged in the surrounding area of the LED lights. Through significantly improving the local back light effect of the area below the lenses and the surrounding area of the LED lights, the LED light source back light module improves the brightness of the area above the lenses and the color of the area, raises substantially the overall backlight effect, and improves the overall visual experience of television and the like.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an LED light source backlight module and a display device. Background technique [0002] With the development of the LCD TV industry, the backlight design technology of various manufacturers is changing with each passing day, and new solutions emerge in an endless stream. At present, there are two main methods of backlight for LCD TVs: direct-type backlight, generally using LED (light-emitting diode) light strips with optical lenses, and the light strips are directly attached to the backlight of the backlight, so that the main light is almost vertical Evenly irradiates the outer membrane and LCD panel; the side-type backlight uses certain optical components (such as light guide plates) to change the light transmission angle, and guides the light to direct the membrane and LCD panel to achieve uniform backlight. in, Figure 1 to Figure 4 It is the structural diagram and light...
