摘要： A defect detection circuit and a defect detection method for a light-emitting element, a display driving device, a display device, and a defect detection method for the display device are provided. The defect detection circuit includes a power source signal adjustment sub-circuit, a data signal adjustment sub-circuit, a first initial signal adjustment sub-circuit, a second initial signal adjustment sub-circuit and a storage capacitor connected to a control end of a driving transistor. The storage capacitor is configured to control the driving transistor to be turned off under the effect of a power source signal, a data signal and an initial signal, to enable the second initial signal adjustment sub-circuit to apply the initial signal to a light-emitting sub-circuit, thereby to enable the light-emitting sub-circuit to emit light. The display driving device includes the defect detection circuit.

摘要： The present disclosure relates to a power supply device for a display panel, a manufacturing method, a power supplying method, and a display device. The power supply device may include: a first line surrounding the display panel and electrically connected to sub-pixels of the display panel; at least one first power supply terminal disposed at a first side of the display panel and connected to a first line segment of the first line located at the first side of the display panel; at least one second power supply terminal connected to a second line segment of the first line located at a second side of the display panel to compensate for a voltage drop of the first power supply terminal on the first line. The first side and the second side of the display panel are opposite sides of the display panel.

摘要： The present disclosure provides a signal loading method and a signal generator. The signal loading method includes: loading a first pair of voltage signals to at least one pair of separate signal channels for a time period, respectively, wherein the first pair of voltage signals have a first voltage difference therebetween; and determining whether a short circuit occurs in the at least one pair of signal channels within the time period, and if it is determined that no short circuit occurs in the at least one pair of signal channels within the time period, loading a second pair of voltage signals having a second voltage difference therebetween to the at least one pair of signal channels at the end of the time period. The second voltage difference is greater than the first voltage difference.
