Embodiment Construction

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0053] The transistors used in all embodiments of the present invention may be triodes, thin film transistors or field effect transistors or other devices with the same characteristics. In the embodiment of the present invention, in order to distinguish the two poles of the transistor except the control pole, one pole is called the first pole, and the other pole is called the second pole.

[0054] In actual operation, when the transistor is a triode, the contr...

Abstract

The invention provides a light emitting unit and a lighting method thereof, a driving unit, a driving circuit and a display device. The light emitting unit comprises N light emitting layers and N+1 electrode layers. The N light emitting layers and the N+1 electrode layers are stacked. The nth light emitting layer is arranged between the nth electrode layer and the n+1 electrode layer, wherein N isan integer greater than 1 and n is a positive integer less than or equal to N. The opening rate of the display panel can be improved and the service life of the light emitting unit can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a light emitting unit, a lighting method thereof, a driving unit, a driving circuit and a display device. Background technique [0002] The OLED (Organic Light Emitting Diode) display panel is gradually becoming the mainstream display panel of the next generation. Generally speaking, the pixel circuit in the OLED display panel includes a light emitting unit, a thin film transistor, and a storage capacitor. By charging the driving voltage corresponding to the display data to the storage capacitor, the light emission of the light emitting unit is controlled by adjusting the magnitude of the driving voltage. brightness. [0003] As the display resolution requirements increase year by year, more pixels need to be designed on a display panel of the same size, which poses great challenges to the aperture ratio, lifespan and drive of pixel design. And in the prior art, due to...
