Problems solved by technology

[0004] However, OLED display devices in the related art are generally powered by DC, so the transport direction of holes and electrons is fixed.
With the prolongation of the service life of the OLED display device, a lot of unrecombined carriers accumulated in the internal interface of the light-emitting layer will cause a built-in electric field to form inside the OLED, resulting in a continuous increase in the threshold voltage of the OLED, and a continuous decrease in its luminous brightness. The energy utilization efficiency is also gradually reduced, which in turn affects the service life of the OLED display device

Abstract

The invention discloses a display panel, a drive method therefor, and a display device, and belongs to the technical field of display. The display panel comprises a plurality of subpixels arranged in an array. The plurality of subpixels arranged in the array comprise at least one target subpixel, and each target subpixel comprises a first electrode, a second electrode, and N light-emitting units which are disposed between the first electrode and the second electrode in an overlapped manner, wherein N is an integer greater than one. In the N light-emitting units, transparent electrodes are respectively disposed between any two adjacent light-emitting units, and each light-emitting unit is driven by two electrodes adjacent to the light-emitting unit to emit light. Therefore, during the driving of the display panel, each light-emitting unit is driven by the electrodes at two sides of the light-emitting unit, and the plurality of light-emitting units are controlled to operate alternately, thereby reducing the working time of each light-emitting unit, and prolonging the service life of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] With the development of display technology, Organic Light Emitting Diode (English: Organic Light Emitting Diode; abbreviation: OLED), as a current-type light-emitting device, has become more and more popular due to its characteristics such as self-illumination, fast response, and wide viewing angle. It is widely used in the field of high-performance display. [0003] In the related art, an OLED display panel generally includes an anode, a light emitting unit and a cathode formed on a base substrate. Wherein, the light emitting unit may specifically include an electron transport layer, a light emitting layer and a hole transport layer. When a voltage is applied to the anode and cathode, electrons can migrate from the cathode to the light emitting layer through the electron tra...
