Abstract

The invention discloses a pixel driving circuit, a driving method and a display device. The pixel driving circuit comprises a light-emitting master control module, a driving module and a light-emitting group module which are sequentially connected in series between a first power supply signal end and a second power supply signal end; a light-emitting master control module connected with the first power supply signal end and the driving module and is configured to control the light-emitting group module to emit light; a driving module which is respectively connected with the light-emitting main control module and the light-emitting group module and is configured to control the magnitude of current flowing through the light-emitting group module; and a light-emitting group module which comprises a plurality of light-emitting devices and corresponding control circuits, is respectively connected with the driving module and the second power supply signal end, and is configured to control the plurality of light-emitting devices to be connected in series and emit light simultaneously in a first mode or control the plurality of light-emitting devices to be connected in parallel and emit light in a time-sharing mode. According to the pixel driving circuit, the pixel density can be adjusted, and power consumption can be reduced when the pixel driving circuit works at a low pixel density.

Description

technical field [0001] This article relates to but not limited to the field of display technology, and in particular relates to a pixel driving circuit, a driving method and a display device. Background technique [0002] LED (Light Emitting Diode, Light Emitting Diode), as a light emitting element, has been widely used in a large-size borderless display panel. Since the light-emitting device and the driving circuit need to be formed in the display area, the number and area of ​​switching tubes (such as thin film transistors) in the driving circuit will affect the pixel density, that is, PPI (Pixel Per Inch, the number of pixels per inch). [0003] With the pursuit of higher PPI, the power consumption of display panels is increasing. Contents of the invention [0004] Embodiments of the present disclosure provide a pixel driving circuit, a driving method, and a display device. [0005] In a first aspect, the present disclosure provides a pixel driving circuit, including:...
