Abstract

The embodiment of the invention provides a voltage regulation circuit, a display module and a display device, wherein the voltage regulation circuit comprises a power supply input end; a voltage stabilizing module, wherein the first input end of the voltage stabilizing module is electrically connected with the power input end; the output end of the voltage stabilizing module is electrically connected with a target node; the target node is a node on a target voltage signal line of the display module; and the voltage stabilizing module is used for adjusting the voltage of the output end of the voltage stabilizing module when the voltage value of the target node is changed from a target voltage value, and keeping the voltage value of the target node at the target voltage value. According to the embodiment of the invention, the voltage value of the target node can be kept at the target voltage value, it is ensured that the voltage value of the target node does not change along with the change of the lightening condition of the display module, and then it can be ensured that the display effect of the display module can reach the expected effect.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a voltage regulation circuit, a display module and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display screens have the advantages of high visibility, high brightness, and thinner and thinner. Therefore, OLEDs are more and more widely used. [0003] The inventors of the present application found that when the lighting conditions of the OLED display module change, the voltage values ​​of each voltage signal line in the OLED display module will change, causing the display effect of the OLED display module to deviate from the expected effect. . Contents of the invention [0004] Embodiments of the present application provide a voltage regulation circuit, a display module, and a display device, which can ensure that the voltage value of the target voltage signal line in the OLED display module remains at the target vol...
