Abstract

The invention provides a backlight module and a display device. The display device comprises the backlight module and a display panel. The backlight module comprises a light guide plate, a base, a first LED and a second LED. The base is arranged on one side of the light guide plate, the first LED is arranged on a first setting face of the base, and the second LED is arranged on a second setting face of the base. The distance between the first LED and the bottom face of the base is larger than the distance between the second LED and the bottom face of the base. The invention can improve the problem of color offset and improve the light coupling effect of the LEDs.

Description

【Technical field】 [0001] The invention relates to a backlight module and a display device, in particular to a backlight module and a display device which can improve the problem of color shift. 【Background technique】 [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal display panel and a backlight module. The backlight module can be divided into side-light type and direct-light type according to different incident positions of the light source, so as to provide backlight to the liquid crystal display panel. [0003] Because light-emitting diodes (Light-Emitting Diode, LED) have good photoelectric characteristics such as low power consumption, low heat generation, long operating life, impact resistance, small size, fast response, and can emit color light with stable wavelengths, they are suitable for applications. The light source for the backlight module. ...
