Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0027] figure 1 It is a schematic diagram of brightness ratios of organic light-emitting elements of different colors under different viewing angles. Such as figure 1 As shown, the organic light emitting element R with a red light emission color, the organic light emitting element G with a green light emission color, and the organic light emitting element B with a blue light emission color have different brightness decay speeds under large viewing angles. Wherein, when the viewing angle is greater than 40°, the ...

Abstract

The embodiment of the invention provides an organic light-emitting display panel and a display device. A polarizer is arranged on one side, deviating from a substrate, of an organic light-emitting element of an organic light-emitting display panel, and the polarizer comprises a polarizing layer; in a first display area of the organic light-emitting display panel, the polarizing layer comprises a plurality of polarizing areas, and the polarizing areas corresponding to the areas where the organic light-emitting elements with different light-emitting colors are located are set to be different inthickness, wherein the longer the wavelength of the emergent light of the organic light-emitting elements are, the smaller the thickness of the polarization areas corresponding to the area where the organic light-emitting elements are located are. According to the organic light-emitting display panel provided by the embodiment of the invention, the brightness of the organic light-emitting elementsof different light-emitting colors of the organic light-emitting display panel tends to be consistent under a large viewing angle, the problem of viewing angle color cast can be solved, and the display effect of the organic light-emitting display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device, also known as organic light-emitting diode display device, has self-illumination, rich colors, fast response speed, wide viewing angle, light weight, thin thickness, low power consumption, Advantages such as flexible display can be realized, and there is a huge application prospect in the display field. [0003] An OLED display panel includes a plurality of pixel units, and each pixel unit may include a plurality of organic light-emitting elements of different light-emitting colors, for example, a pixel unit may include a red organic light-emitting element (R), a green organic light-emitting element (G) and a blue organic light-emitting element (G). Organic light-emitting elements (B), etc., differe...
