Problems solved by technology

However, there is no color resistance scheme in the through hole area, and RGB color images cannot be displayed normally; and in order to ensure the imaging effect of the camera, RGB color resistance cannot be prevented on the color filter substrate side, because RGB color resistance will absorb light

Abstract

The invention provides a backlight module and a display device. The backlight module includes a substrate, a reflection sheet, a light guide plate, a diffusion film, a reflection layer, a transparent film layer, and a backlight source. In the invention, the substrate is spliced ​​at the reflection sheet, and At the junction of the substrate and the reflective sheet, due to the high reflectivity of the reflective layer, the reflective layer can effectively replace the function of the reflective sheet, thereby ensuring the ductility of light and reducing the requirements for assembly accuracy. In addition, the white light emitting unit can be used at the splicing place, and the MiniLED can be individually controlled to realize the difference in the light intensity of the MiniLED at different positions, thereby solving the phenomenon of black edges and dark edges at the splicing place, and can better realize a comprehensive screen display. Compensate the phenomenon of uneven light emission of the backlight module due to digging holes.

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] With the improvement of the overall process design capabilities of mobile phones, consumers' aesthetics are constantly being guided and improved. Therefore, the overall trend of mobile phone screens has gradually shifted to the direction of full-screen design. Therefore, in display screens such as chip-on-film (COF), ultra-narrow bezel, and heterosexual screens, the design capabilities and process capabilities of full-screen related indicators have been continuously improved in less than a year, and the screen-to-body ratio of the screen has also increased from 80. % gradually increased to 97%. However, with the rapid improvement of the above capabilities, it has reached a relative bottleneck period. Therefore, the in-screen hole-digging technology has emerged as the times require. In-plane digging can furth...
