The present invention provides a backlight module and an electronic device. In the backlight module, a plurality of first light sources are arranged on one side of a substrate along a first direction and a second direction. The protruding structure and the first light source are arranged on the same side of the substrate, and the orthographic projection of the protruding structure on the plane of the substrate does not overlap with the orthographic projection of the first light source on the plane of the substrate. The protruding structure includes a first protruding structure and a second protruding structure, the first protruding structure includes a first control switch, a first shielding layer and a first reflecting layer, at least one first light source and It is electrically connected with a first control switch, and the second protruding structure includes a second reflective layer. It can be seen that this solution controls a light source partition through the first control switch to realize local dimming, and reflects the light between adjacent first light sources through the first reflective layer and the second reflective layer, eliminating the need for the first light source The light interference between them avoids the problem of poor brightness uniformity.
Description
technical field [0001] The present invention relates to the field of display technology, more specifically, to a backlight module and electronic equipment. Background technique [0002] With the continuous development of liquid crystal display technology, liquid crystal display modules have been widely used in electronic devices such as mobile phones and tablet computers. However, since the liquid crystal display panel in the liquid crystal display device does not have the function of emitting light, it is necessary to install a backlight module under the liquid crystal display panel to provide the required light source to achieve the display effect. [0003] Generally, the luminous effect of the backlight module will directly affect the visual effect of the liquid crystal display module, and the backlight module can be divided into side-type and direct-type according to the position of the light source. The partitions of the LEDs in the direct-lit backlight module can corr...
