摘要

The disclosure discloses a compensation method and device of an organic light-emitting diode display panel, and an organic light-emitting diode display device. A high-voltage signal received at a first electrode of a driver transistor in the pixel circuit is detected when a light-emitting element in the pixel circuit is emitting light in the current frame. Then the voltage difference between the high-voltage signals received by the driver transistor in the current frame and a preceding frame, i.e., compensation voltage, is determined according to the detected high-voltage signal received by the pixel circuit in the current frame, and the pre-stored high-voltage signal received by the pixel circuit in the preceding frame. When the compensation voltage lies out of a preset range, voltage compensation is performed on a reference voltage signal applied to the pixel circuit according to the compensation voltage.

說明書

An embodiment of the disclosure provides a compensation method of an organic light-emitting diode display panel, including: detecting a high-voltage signal received at a first electrode of a driver transistor in a pixel circuit in the organic light-emitting diode display panel in a current frame when a light-emitting element in the pixel circuit is emitting light; determining compensation voltage corresponding to the pixel circuit according to the detected high-voltage signal received by the pixel circuit in the current frame, and a pre-stored high-voltage signal received by the pixel circuit in a preceding frame, wherein the compensation voltage is the voltage difference between the high-voltage signal received in the current frame, and the high-voltage signal received in the preceding frame; and performing voltage compensation on a reference voltage signal applied to the corresponding pixel circuit according to the compensation voltage when the compensation voltage lies out of a preset range.
