Problems solved by technology

However, in the existing OLED display device with RGBW pixel structure, since the sub-pixel unit displaying white is always in the light-emitting stage compared with the sub-pixel unit displaying red, green or blue during use, the displaying white The life of the sub-pixel unit will be reduced, which will reduce the life of the entire OLED display device

Embodiment Construction

[0029] The specific implementation manners of the organic electroluminescent display device provided by the embodiments of the present invention, its driving method and the display device will be described in detail below with reference to the accompanying drawings.

[0030] The shapes and sizes in the drawings do not reflect the true scale of the organic electroluminescence display device, but are only intended to schematically illustrate the content of the present invention.

[0031] An organic electroluminescent display device provided by an embodiment of the present invention, such as figure 2 and image 3 As shown, it includes a plurality of pixel units 100 arranged in a matrix, and each pixel unit 100 is composed of a plurality of sub-pixel units 110 displaying different colors. In each row of pixel units 100, two adjacent pixel units 100 are A set of pixel cell groups;

[0032] Each pixel unit group also includes a white sub-pixel unit 120 located between two adjacen...

Abstract

The invention discloses an organic electroluminescence display device and a driving method thereof, and a display apparatus. In the OLED display device, in each pixel unit group, sub-pixel units for displaying white are located between two adjacent pixel units, and the area occupied by the sub-pixel unit for displaying white is greater than the area occupied by any sub-pixel unit in the pixel unit, so compared with an existing OLED display device, the area occupied by a single sub-pixel unit for displaying white is increased, and the aperture opening ratio of a single sub-pixel unit for displaying white can be increased, so that the driving current and power consumption of the sub-pixel units for displaying white can be reduced, and finally, the service life of the OLED display device can be prolonged; and the brightness of light emitted by the sub-pixel units for displaying white is used to replace the brightness of light emitted by one pixel unit of two adjacent pixel units according to a preset condition, so the overall display brightness of the OLED display device can be ensured in the display process.

Description

technical field [0001] The invention relates to the technical field of display, in particular to an organic electroluminescence display device, a driving method thereof and a display device. Background technique [0002] At present, compared with traditional liquid crystal display devices (Liquid Crystal Display, LCD), organic electroluminescent display devices (Organic Electroluminescent Display, OLED) have the characteristics of fast response, wide color gamut, ultra-thin, and flexibility. Has gradually become the mainstream of the display field. [0003] The structure of the OLED display device mainly includes: a base substrate, an organic electroluminescent pixel array fabricated on the substrate substrate; wherein, each organic electroluminescent pixel array includes an anode and a cathode arranged oppositely, and between the luminous layers. The light emission of the OLED display device is realized by exciting the organic material in the light-emitting layer to emit ...
