Embodiment Construction

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] The transistors used in all the embodiments of the present invention may be triodes, thin film transistors, 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 tran...

Abstract

The invention provides a light emitting unit and its lighting method, a driving unit, a driving circuit and a display device. The light emitting unit includes N light emitting layers and N+1 electrode layers, the N light emitting layers and the N+1 electrode layers are arranged in layers, and the nth light emitting layer is arranged between the nth electrode layer and the n+th electrode layer 1 Between electrode layers; N is an integer greater than 1, and n is a positive integer less than or equal to N. The invention can increase the aperture ratio of the display panel, and can increase the service life of the light emitting unit.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a light-emitting unit and a lighting method thereof, a driving unit, a driving circuit and a display device. Background technique [0002] OLED (Organic Light Emitting Diode) display panels are gradually becoming the next-generation mainstream display panels. Generally speaking, a pixel circuit in an OLED display panel includes a light-emitting unit, a thin film transistor and a storage capacitor. By charging the storage capacitor with a driving voltage corresponding to display data, the size of the driving voltage is adjusted to control the light-emitting of the light-emitting unit. brightness. [0003] As the requirement of display resolution increases year by year, more pixels need to be designed on a display panel of the same size, which is a great challenge to the aperture ratio, lifespan and driving of pixel design. In the prior art, due to the limitation of...
