Abstract

The invention provides a backlight module and a display panel, the backlight module comprises a substrate, a backlight source and a reflective retaining wall, the backlight source is arranged on the substrate, the backlight source comprises a plurality of light mixing units arranged in an array, each light mixing unit comprises two rows of LED chips arranged in a staggered mode, and the reflective retaining wall is arranged on the substrate. Each row of LED chips comprises a red light LED chip, a green light LED chip and a blue light LED chip; the light emitting color of any LED chip in the light mixing unit is different from the light emitting colors of all the adjacent LED chips; and the reflective retaining wall is arranged on the substrate, surrounds the light mixing unit and separates the three LED chips at one end of the light mixing unit from the three LED chips at the other end of the light mixing unit. According to the backlight module, the light mixing uniformity can be improved.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a backlight module and a display panel. Background technique [0002] The backlight module is a device in the display panel that provides a light source for the liquid crystal cell, and its luminous effect and performance parameters directly affect the visual effect of the display panel. LED light-emitting elements have the advantages of excellent optoelectronic performance and small size, so they have gradually become the mainstream light sources in backlight modules. The LED light-emitting elements used in the direct-type backlight module are increasingly miniaturized. After the size of the LED light-emitting element becomes smaller, the LED light-emitting elements in the backlight module are made more dense, which reduces the light mixing distance and the thickness of the module. The display panel is energy-saving, thin and light, and has a high color g...
