Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] figure 1 is a schematic structural view of an OLED display substrate provided by an embodiment of the present invention, as shown in figure 1 As shown, the OLED display substrate includes a plurality of pixels 200, and each pixel 200 includes three sub-pixels (such as figure 1 in the first sub-pixel 210, the second sub-pixel 220 and the third sub-pixel 230).

[0032] figure 2 yes figure 1 A-A cross-sectional diagram in, such as figure 2 As shown, each sub-pixel includes two light-emitting units stacked (such as figure 2 in the first light emitting unit 211 and the second light emitting unit 212). At most one of the two light emitting units of the same sub-pixel emits light at the same time.

[0033] In the embodiment o...

Abstract

The invention discloses an OLED display substrate and a display apparatus, and belongs to the field of the display apparatus. The OLED display substrate comprises multiple pixels in array arrangement; each pixel comprises multiple sub pixels; each sub pixel comprises two light emitting units arranged in a stacked manner; at most one of the two light emitting units of the same sub pixel can give out light at the same moment; each pixel on the OLED display substrate comprises multiple sub pixels; each sub pixel comprises two light emitting units arranged in a stacked manner; at most one of the two light emitting units of the same sub pixel can give out light at the same moment, so that when one light emitting unit is in a light-emitting state, the other light emitting unit is not in the light-emitting state; and therefore, the continuous switch-on time of the same light emitting unit can be reduced, so that the light emitting units have enough time to be dissipated, the light emitting units can be protected effectively, and device aging can be slowed down, thereby prolonging the service life of the display apparatus.

Description

technical field [0001] The invention relates to the field of display devices, in particular to an OLED display substrate and a display device. Background technique [0002] Currently common display devices include passive light emitting display devices (such as liquid crystal display devices) and active light emitting display devices (such as OLED (Organic Light Emitting Diode, organic light emitting diode) display devices). Compared with the passive light-emitting display device, it has the advantages of smaller thickness, low power consumption, fast response speed, etc., so the active light-emitting display device has greater market competitiveness. [0003] In an OLED display device, each pixel includes three sub-pixels, and the three sub-pixels respectively emit light of different colors. By controlling the light-emitting brightness of the three sub-pixels in the same pixel, the pixel can display different colors. [0004] However, due to the short service life of organ...
