A direct type backlight display module and a display device are disclosed. The direct type backlight display module includes a backlight module (100) and a liquid crystal panel (300) corresponding to each other, and a main control circuit (400) connected to the backlight module (100) and the liquid crystal panel. The backlight module (100) includes a back plate (110), a light emitting structure disposed on the back plate (110), a diffusion plate (140) directly facing the light emitting structure, and an electromagnetic input module (200) disposed between the light emitting structure and the liquid crystal panel (300). The electromagnetic input module (200) includes an electromagnetic diaphragm (200) disposed between the light emitting structure and the liquid crystal panel (300), and an electromagnetic control circuit electrically connected to the electromagnetic diaphragm (210), the electromagnetic diaphragm having a transmittance greater than or equal to 50%. The electromagnetic diaphragm (210) is connected to the main control circuit (400) through the electromagnetic control circuit. According to the technical solution, the electromagnetic touch input is may integrally integrated into the direct type backlight display module, and it can be ensured that a liquid crystal screen has a good display effect.
