Abstract

The invention discloses a backlight module and a display module. The backlight module comprises a side-entry light source, a light guiding plate, a first prism combination and a light guiding element,wherein the light guiding plate is provided with a backlight hole which penetrates through the light guiding plate in a thickness direction; the first prism combination comprises at least one first prism, is arranged in the backlight hole, and is positioned on the side, which is close to the light source, of the light guiding plate; the light guiding element surrounds the inner side wall of the backlight hole; the first prism combination is positioned between the light guiding element and the light guiding plate, and is in partially contact with the light guiding element at least; and part ofincident light from the light source is emitted out from a light transmitting region on the side, which is away from the light source, of the backlight hole via the first prism combination and the light guiding element. The technical problem that a screen with a hole in a display region in the prior art has shadows during displaying is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] At present, in order to increase the screen-to-body ratio of terminal devices such as smartphones, technical solutions for setting electrical components (such as front cameras, mechanical keys, fingerprint modules, etc.) in the display area of ​​the screen have been proposed. The display area is provided with holes to accommodate electrical components, such as figure 1 The area C' shown in is the area where the preset holes in the screen are located. [0003] However, when using as figure 2 In the case of the backlight module of the side-type light source shown, the preset hole C in the backlight module will hinder the normal transmission of part of the light generated by the light source D, thereby causing the part of the area behind the area C' to form a dark shadow visually . Contents of the inventio...
