Abstract

The embodiment of the invention discloses a digital pixel driving circuit, a driving method thereof, and a display panel. The digital pixel driving circuit includes: a driving module, a data writing module, a brightness adjustment module and a storage module; the driving module includes a control terminal, and the driving module is used to control the light emitting state of the light emitting device according to the voltage of the control terminal; The data writing module is used to write the data signal into the storage module; the brightness adjustment module is used to write the refresh signal into the storage module; the storage module is used to store the data signal, and according to the data The signal maintains the voltage of the control terminal of the driving module; and stores the refresh signal, switches and maintains the voltage of the control terminal of the driving module according to the refresh signal, so as to adjust the light-emitting time of the light-emitting device. Compared with the prior art, the embodiments of the present invention enrich the way of brightness adjustment, which is more conducive to flexible control of the brightness of the light emitting device.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a digital pixel driving circuit, a driving method thereof, and a display panel. Background technique [0002] With the continuous development of display technology, the application range of display panels is becoming wider and wider, and people's requirements for display panels are also getting higher and higher. [0003] The digital pixel driving circuit in the display panel plays a very important role in driving the light emitting device to emit light stably. However, the performance of the existing digital pixel driving circuit is not ideal, and there is a problem of single brightness adjustment. Contents of the invention [0004] Embodiments of the present invention provide a digital pixel driving circuit, a driving method thereof, and a display panel, which realize the effect of flexibly controlling brightness by means of rich brightness adjustm...
