Abstract: A repairing method for micro-LED chip defective pixels is disclosed. By providing a main recess and a backup recess in each of sub-pixel areas of a substrate, wherein each of the main recesses is loaded with a main micro-LED chip, when all of the main micro-LED chips are detected for defective pixels, the backup recess in each of the sub-pixel areas where the defective pixel is detected is loaded with a backup micro-LED chip using a fluid mass transfer method, which improves the repair efficiency.

Abstract: The present disclosure provides a liquid crystal display panel and a display device. The liquid crystal display panel includes an upper substrate and a lower substrate disposed opposite to the upper substrate. The lower substrate includes a non-display area having a connection terminal disposed therein. The connection terminal has an elongated stripe shape. By replacing the connection terminal having a square shape or a square-like shape with a connection terminal having an elongated stripe shape, light-reflection problems caused by metal having a large area in a local region are mitigated. Therefore, the technical problem that user experiences of using display devices are unsatisfactory because of light-reflection issues caused by conventional connection terminal is solved.

Abstract: The invention provides a GOA circuit and driving method therefor, and a display panel. The GOA circuit includes a GOA unit. The GOA unit includes a forward and reverse scan control module, a node signal control module, a voltage regulator module, an output control module, a first pull-down module, and a second pull-down module. When the second pull-down module is in operation, the forward and reverse scan control module controls the voltage regulator module to be in an off state, so that the GOA circuit has no transistor in the on state for a long time, thus to suppress threshold voltage drift in transistors.
