Problems solved by technology

However, the reduction of the pixel pitch and the increase of the driving voltage lead to the phenomenon that the undriven sub-pixels next to the driven light-emitting sub-pixels of the WOLED display panel also emit light weakly, that is, the phenomenon of light leakage.
The occurrence of light leakage will reduce the color gamut of the display and lead to a decrease in display quality.

Abstract

The present invention provides a WOLED display device. The device comprises a substrate and a plurality of WOLED devices; the substrate comprises a plurality of pixel areas in array arrangement; each WOLED device comprises an anode layer, a hole injection layer and multiple luminescent layers, and one charge generation layer is arranged between each two adjacent luminescent layers; and the hole injection layer and / or at least one charge generation layer are arranged corresponding to the pixel areas and are disconnected at the upper portion between the two corresponding adjacent pixel areas. The WOLED display device performs improvement on the physical structure of the WOLED display device to allow the hole injection layer and the charge generation layers not to have the transverse conduction feature when the pixel distance is small and the driving voltage is high so as to effectively avoid the occurrence of the light leakage phenomenon.

Description

technical field [0001] The invention relates to the field of flat panel displays, in particular to a WOLED display device. Background technique [0002] The active matrix flat panel display has many advantages such as thin body, power saving, and no radiation, and has been widely used. Among them, organic light-emitting diode (OLED) display technology is a promising flat panel display technology, which has very excellent display performance, especially self-illumination, simple structure, ultra-thin, fast response , wide viewing angle, low power consumption, and flexible display, it is known as a "dream display", and its production equipment investment is much smaller than that of a thin film transistor-liquid crystal display (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) , has been favored by major display manufacturers, and has become the main force of the third-generation display devices in the field of display technology. At present, OLED is on the eve of mass ...
