Problems solved by technology
[0004] However, when two light-emitting elements in each sub-pixel of the display panel are arranged in series, only the sub-pixel can emit light when both light-emitting elements are normal, resulting in a low manufacturing yield of the display panel; when two light-emitting elements in each sub-pixel of the display panel When the light-emitting elements are arranged in parallel, the driving current is large, resulting in increased power consumption, that is, the display panels of the prior art cannot meet the requirements of high production yield and low power consumption at the same time

The invention discloses a display panel, a display device and a light-emitting element configuration method of the display panel. The display panel comprises a plurality of sub-pixels; each sub-pixel comprises a light emitting module, a gating module and a pixel driving circuit; the light-emitting module comprises a first light-emitting element and a second light-emitting element; the gating module comprises a first gating unit, a second gating unit and a third gating unit; if the first gating unit is switched on, the second gating unit and the third gating unit are switched off, and the first light-emitting element and the second light-emitting element are connected in series; if the first gating unit is disconnected, the second gating unit and the third gating unit are connected, and the first light-emitting element and the second light-emitting element are connected in parallel. According to the display panel, the display device and the light-emitting element configuration method of the display panel, the requirements of high manufacturing yield and low power consumption can be met at the same time.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a display device, and a method for arranging light-emitting elements of the display panel. Background technique [0002] With the continuous development of display technology, more and more electronic devices with display functions are widely used in people's daily life and work, bringing great convenience to people's daily life and work. [0003] The main component of an electronic device to realize a display function is a display panel. Existing display panels generally include a plurality of sub-pixels arranged in an array, each sub-pixel includes two light-emitting elements and a pixel driving circuit electrically connected to the light-emitting elements, and the pixel driving circuit provides a driving current for the light-emitting elements to drive the light-emitting elements to emit light . Wherein, the connection mode of the...
