Abstract

The invention discloses a display panel, a drive method and a display device. The display panel comprises a plurality of data signal lines, scanning signal lines and an external compensation circuit, wherein the scanning signal lines are in cross connection with the data signal lines to define a plurality of arrayed subpixels, and each subpixel comprises a pixel drive circuit; the external compensation circuit comprises a power supply unit, a sampling unit and a data signal generating unit, and the external compensation circuit is connected with the data signal lines and transmits compensated data signals to the pixel drive circuits. The display panel has the advantages that the external compensation circuit is used to perform voltage compensation on the drive transistors and organic light-emitting diodes of the pixel compensation circuit, the drive ability of the pixel drive circuit is increased, and the display precision of the display panel is increased.

Description

technical field [0001] The present disclosure generally relates to the field of display technologies, and in particular, to a display panel, a driving method applied to the display panel, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is a device made of organic semiconductor material and driven by current to generate reversible discoloration to realize display. The existing organic light-emitting diodes can be divided into passive driving mode (Passive Matrix, PMOLED) and active driving mode (ActiveMatrix, AMOLED) according to the driving mode. In the pixel driving circuit, compared with the passive driving mode, the active driving mode Each pixel in the device can emit light at the same time, which reduces the luminous brightness of a single pixel, makes up for the lack of improvement in the brightness of organic light-emitting diodes in the passive drive circuit, reduces circuit power consumption, and ...
