Abstract: Provided are a display panel including multiple scan lines located in the display region and gate drive unit groups located in a non-display region. The gate drive unit groups include at least one first gate drive unit group and at least one second gate drive unit group. The first gate drive unit group includes multiple cascaded first gate drive units. The second gate drive unit group includes multiple cascaded second gate drive units. The first gate drive units and the second gate drive units are connected to different scan lines. A first period during which a first gate drive unit at the first stage transmits an effective level signal to a scan line and a second period during which a second gate drive unit at the first stage transmits an effective level signal to a scan line overlap, overlap duration is t, and t>0.

Abstract: A power-on reset system includes a reset signal generator, a power-on reset module and a D flip-flop. The reset signal generator generates a reset enable signal when powered on, and the reset enable signal is input to the power-on reset module and the D flip-flop. An output end of the power-on reset module is connected with a clock end of the D flip-flop, an output end of the D flip-flop is connected with a control end of the power-on reset module, and an output signal of the power-on reset module controls the output reset signal of the D flip-flop. When a voltage of the enable end of the power-on reset module is a high level, the power-on reset module is turned off. In such a way, the entire power-on reset system generates no power consumption, thereby improving the working performance of the entire system chip.

Abstract: A light-emitting substrate, a display panel, a backlight module, a display device and a driving method. The light-emitting substrate has a light-emitting region and includes a plurality of light-emitting elements located in the light-emitting region and configured to emit light of different colors. The plurality of light-emitting elements includes an edge light-emitting element adjacent to an edge of the light-emitting region, and a first light-emitting element adjacent to the edge light-emitting element, and the edge light-emitting element is configured to emit light of a first color, and the first light-emitting element is configured to emit light of a second color different from the first color.
