Abstract: The present application provides a backlight module and a display device, including a light source component, a quantum dot component, and a wavelength-band-light-reflecting component being arranged in a stack. The wavelength-band-light-reflecting component reflects light emitted by the quantum dot component in a specific band range, so as to reduce full width at half maximum of the light. The present application reduces the full width at half maximum of monochromatic light by arranging the wavelength-band-light-reflecting component reflecting light in the specific band range, thereby increasing gamut of a display module.

Abstract: The present application provides a display panel control method and a display module. A display voltage corresponding to corresponding pixel unit can be compensated for based on a difference between a first feed-through voltage generated by a pixel electrode when a first transistor is turned from on to off and a second feed-through voltage generated by a common electrode when a second transistor is turned from on to off, so as to improve the problem such as the flicker or the image sticking in the display picture due to the unevenness of the feed-through voltages.

Abstract: A pixel driving circuit, a driving method thereof, and a display panel are disclosed. A second transistor stores a threshold voltage of a first transistor in a first capacitor according to a second scan signal, so as to compensate an influence of the threshold voltage on a driving current. A fifth transistor makes a voltage difference between a first node and a second node irrelevant to a second voltage signal according to a fourth scan signal, so as to improve a current attenuation issue caused by a voltage drop during a signal transmission.
