Driving circuit, driving method thereof and display device

Abstract

The invention provides a driving circuit, a driving method thereof and a display device. The driving circuit comprises a current source module which is respectively connected with a to-be-driven element and a first data line and is used for receiving a first data signal through the first data line and controlling the magnitude of driving current provided for the to-be-driven element according to the first data signal; a time control module which is respectively connected with the current source module, a second data line and a pulse signal end, and is used for receiving a second data signal through the second data line, receiving a periodic pulse signal through the pulse signal end, and controlling the duration of providing driving current for the element to be driven by the current source module in each driving period according to the second data signal and the periodic pulse signal. According to the invention, the display defect caused by a light-emitting device of which the characteristic easily drifts with the current density can be reduced, and the display performance of a related display product is improved.

Description

technical field [0001] The present disclosure relates to the display field, and in particular to a driving circuit, a driving method thereof, and a display device. Background technique [0002] Electroluminescence (Electroluminescent, EL) refers to the phenomenon that when a current passes through a substance or a substance emits light under a strong electric field, this phenomenon can be used to make an electroluminescent device, such as an organic light-emitting diode (Organic Light-Emitting Diode, OLED), Quantum Dot Light Emitting Diode (QLED), Micro Light Emitting Diode (Micro Light Emitting Diode, MicroLED) and other types of light emitting devices. [0003] Depending on the device type, the characteristics of some light emitting devices are prone to drift with changes in current density. That is, as the current density changes, these light-emitting devices not only have significant changes in light emission luminance, but also significant changes in other characterist...

AI Technical Summary

Problems solved by technology

For example, the luminous color coordinates of some light-emitting devices will shift significantly when the current density is too small or too high, and for example, the luminous efficiency of some light-emitting devices will be too low within a certain range of current density

When applied to displays, light-emitting devices with these characteristics are prone to cause various display defects, such as color cast, too dark picture, too low contrast, etc.
