Embodiment 1

[0030] Please refer to figure 1 , which is a structural schematic diagram of an OLED pixel structure according to Embodiment 1 of the present invention. Such as figure 1 As shown, the OLED pixel structure 100 includes: a plurality of mirror-symmetrically arranged pixel units 110, each pixel unit 110 includes a plurality of sub-pixels, and there are at least two sub-pixels of the same color in the plurality of sub-pixels, so The two sub-pixels of the same color are electrically connected.

[0031] Specifically, each pixel unit 110 may include four sub-pixels, six sub-pixels, eight sub-pixels, nine sub-pixels or even more, and each pixel unit 110 has two, three, four or even more sub-pixels Electrically connected and the same color. Such as figure 1 As shown, taking each pixel unit 110 includes 4 sub-pixels and two sub-pixels have the same color as an example, each pixel unit 110 includes a first sub-pixel 111, a second sub-pixel 112, a third sub-pixel 113 and a Four sub-pi...

Embodiment 2

[0046] Correspondingly, the present invention also provides an organic light emitting display device and a display method thereof. Please refer to Figure 4 , which is a schematic structural diagram of an organic light emitting display device according to Embodiment 2 of the present invention. Such as Figure 4 As shown, the display method of the organic light emitting display device includes:

[0047] Step 1: Provide an organic light emitting display device 20, the organic light emitting display device 20 includes a fixed display area 22 and a non-fixed display area 24, each pixel unit of the fixed display area 22 and the non-fixed display area 24 includes multiple sub-pixels, each pixel unit of the fixed display area 22 has at least two sub-pixels of the same color, and the two sub-pixels of the same color are electrically connected;

[0048] Step 2: Turn on each sub-pixel in the fixed display area, and at the same time turn on the sub-pixels in the non-fixed display area...

Abstract

The present invention provides an OLED pixel structure, an organic light-emitting display device and a display method thereof, wherein the OLED pixel structure includes: a plurality of pixel units arranged symmetrically in a mirror image, each pixel unit includes a plurality of sub-pixels, the There are at least two sub-pixels of the same color among the plurality of sub-pixels, and the two sub-pixels of the same color are electrically connected. In the OLED pixel structure and the display method of the organic light-emitting display device provided by the present invention, each pixel unit in the fixed display area has sub-pixels of the same color and are electrically connected to reduce the pixel current and prolong the pixel unit. service life, so as to solve the problem that the display effect of the organic light-emitting display device decreases due to long-term fixed display.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to an OLED pixel structure, an organic light-emitting display device and a display method thereof. Background technique [0002] Organic light-emitting display device (OLED) is an emerging flat panel display device, which has many advantages such as active light emission, high contrast, fast response speed, light and thin, and is known as a new generation of display device that can replace liquid crystal display (LCD). At present, organic light-emitting display devices have been widely used in various high-performance display fields such as mobile phones, televisions, and computers. [0003] However, in some specific application occasions, the organic light emitting display device needs to be in a specific static picture for a long time. The specific still picture includes a fixed display area and a non-fixed display area, and the OLED pixels in the fixed display area a...
