Embodiment Construction

[0046] The circuit structure for driving pixel display in the electroluminescent display panel in the related art is as follows: figure 1 As shown, the pixel circuit Pixel includes a scanning signal terminal and a light-emitting control terminal (the specific structure of the pixel circuit is not shown), and due to the design of the pixel circuit Pixel structure, the signal of the scanning signal terminal and the signal of the light-emitting control terminal in the pixel circuit Pixel are not identical. It cannot be provided by the same driving circuit, so it is necessary to set two driving circuits (the luminescence control driving circuit EM and the gate driving circuit Gate) in the non-display area of ​​the electroluminescent display to realize the control of the pixel circuit Pixel. However, the two driving circuits occupy a large area of ​​the non-display area, which is not conducive to realizing a narrow frame design.

[0047] In view of the above problems, embodiments o...

Abstract

The invention discloses a pixel circuit, a driving method thereof and an electroluminescent display panel. The pixel circuit comprises a first initialization module, a second initialization module, ananode control module, a data writing module, a driving control module, a light-emitting control module and a light-emitting device. A pixel circuit structure is designed, the potential of the signalprovided by the scanning signal end of the pixel circuit is opposite to the potential of the signal provided by the light-emitting control end, so that a driving signal can be provided for the scanning signal end and the light-emitting control end through one driving circuit, the number of driving circuits is reduced, and the narrow-frame design of the electroluminescent display panel is favorablyrealized.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel circuit, a driving method thereof and an electroluminescence display panel. Background technique [0002] Electroluminescent displays are one of the hot spots in the research field of flat panel displays. Compared with liquid crystal displays, electroluminescent devices have the advantages of low energy consumption, low production cost, self-luminescence, wide viewing angle and fast response speed. In the field of flat panel displays such as PDAs and digital cameras, electroluminescent displays have begun to replace traditional liquid crystal displays. Among them, pixel circuit design is the core technology of electroluminescence display, which has important research significance. [0003] The pixel circuit in the related art includes a scanning signal terminal and a light-emitting control terminal, and the signal of the scanning signal terminal and the signal o...
