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(shuō)明書

In the compensation method above of an organic light-emitting diode display panel according to the embodiment of the disclosure, 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, where the high-voltage signal is a signal used by the driver transistor to generate current in the current frame to drive the light-emitting element connected therewith to emit light; and then the voltage difference between the high-voltage signal received by the pixel circuit in the current frame, and a high-voltage signal received by the pixel circuit in 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, and voltage compensation is performed on a reference voltage signal applied to the pixel circuit according to the compensation voltage when the compensation voltage lies out of a preset range, so that the problem of crosstalk between moving images when a user is touching on the images can be alleviated to thereby improve a display effect of the images.

Those skilled in the art shall appreciate that the embodiments of the disclosure can be embodied as a method, a system or a computer program product. Therefore the disclosure can be embodied in the form of an all-hardware embodiment, an all-software embodiment or an embodiment of software and hardware in combination. Furthermore the disclosure can be embodied in the form of a computer program product embodied in one or more computer useable storage mediums (including but not limited to a disk memory, a CD-ROM, an optical memory, etc.) in which computer useable program codes are contained.
