Problems solved by technology

However, in the above-mentioned OLED display panel, due to the wide spectrum of the light emitted by the light-emitting layer in the light-emitting element after being excited, and the luminous efficiency, lifespan, and influence of temperature of each light-emitting element are not uniform, the color saturation of the OLED display panel Usually lower; in addition, in the above-mentioned OLED display panel, when the light-emitting layer in the light-emitting element is excited to emit light, the light is usually emitted to the surroundings of the light-emitting element, which may cause cross-color phenomenon in the OLED display panel.

Embodiment Construction

[0035] In order to make the above objects, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] As mentioned in the background technology, OLED display panels in the prior art have problems of low color saturation and color crossover. The inventors have found through research that the main reason is that in the pixels of the existing OLED display panels, the light-emitting elements of each sub-pixel The luminous effic...

Abstract

The invention provides an OLED display panel and an OLED display device, which relate to the technical field of display, and aim to improve the color saturation of the OLED display panel and prevent color crossing of the OLED display panel. The OLED display panel comprises a plurality of pixels arranged in an array, each pixel comprises at least three sub-pixels, and each sub-pixel can display light of one color; each sub-pixel comprises a light-emitting element, each light-emitting element can emit first color light, and the wavelength of the first color light is smaller than or equal to thewavelength of light which can be displayed by any sub-pixel; each sub-pixel further comprises a light condensation structure located on the light-emitting side, facing the light-emitting element, of the light-emitting element. In each pixel, quantum dots are dispersed in the light condensation structures in the at least two sub-pixels, and the quantum dots absorb the first color light emitted by the light-emitting element and emit light of one color which can be displayed corresponding to the sub-pixels. The OLED display panel provided by the invention is used for image display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] Organic Light Emitting Diode (OLED) devices, also known as organic electroluminescent diode devices, are self-illuminating, rich in color, fast in response, wide in viewing angle, light in weight, thin in thickness, low in power consumption, and flexible Display and other advantages have drawn wide attention, and OLED display devices made of OLED devices are regarded as display devices with great application prospects, especially in the field of flat panel display, OLED display devices are considered to be a trend. [0003] The OLED display device generally includes an OLED display panel, and a plurality of pixels arranged in an array are arranged in the OLED display panel. According to the color matching mode of the OLED display panel, each pixel includes a corresponding number of sub-pixels. For ex...
