Abstract: Embodiments of the present disclosure provide a color-resist composition and a display panel, and the color-resist composition includes a photocurable resin and a photosensitive monomer. The photosensitive monomer has a chemical structure provided by the embodiments of the present disclosure. The photocurable resin is correspondingly selected from the photocurable resin in the embodiments of the present disclosure. The crosslinking degree of the photocurable resin can be enhanced by adding the photosensitive monomer to the photocurable resin during a preparation process to form a color-resist film layer, which improves the overall performance of the display panel.

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.

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.
