Problems solved by technology

[0004] However, the excited light of the quantum dot layer needs to pass through the entire quantum dot layer, and part of the excited light is reabsorbed by the quantum dot layer during this process, resulting in low brightness and luminous efficiency of the display panel.

Embodiment 1

[0051] figure 1 A schematic structural diagram of a display panel provided for an embodiment of the present invention; please refer to figure 1 . This embodiment provides a display panel, including a plurality of light-emitting units arranged on the array substrate 100, each light-emitting unit includes a first electrode layer, an organic light-emitting layer and a second electrode layer sequentially stacked on the array substrate, the organic light-emitting The light-emitting layer includes a plurality of sub-pixels, at least one sub-pixel includes a light source and a quantum dot layer, a barrier layer is provided on the light output side of the light source, the barrier layer is parallel to the array substrate 100, and the quantum dot layer is provided on the side of the light source.

[0052] Specifically, the sub-pixels in this embodiment may include blue sub-pixels, red sub-pixels and green sub-pixels. When the sub-pixel is a blue sub-pixel, it can include a blue quantum...

Embodiment 2

[0084] This embodiment provides a display device, including the display panel described in Embodiment 1 above. The display device may be a product or component with a display function such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, or a navigator.

[0085] Since the display device provided by this embodiment includes the display panel described in Embodiment 1 above, it also has relatively high luminous efficiency, color gamut width, and light output brightness, and the advantages of the display device provided by this embodiment will not be repeated here. .

Abstract

The invention provides a display panel and a display device. The display panel comprises a plurality of light-emitting units arranged on an array substrate, each light-emitting unit comprises a firstelectrode layer, an organic light-emitting layer and a second electrode layer which are sequentially arranged on the array substrate in a stacked mode, and the organic light-emitting layer comprises aplurality of sub-pixels; and at least one sub-pixel comprises a light source and a quantum dot layer, the light emitting side of the light source is provided with a barrier layer, the barrier layer is parallel to the array substrate, and the quantum dot layer is arranged on the side surface of the light source. The light emitting efficiency and the light emitting brightness of the display panel can be effectively improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Display screens have been widely used in many fields such as portable electronic devices (such as mobile communication terminals, tablet computers, e-books, and navigation equipment) and large-screen electronic devices. Among them, organic light-emitting diodes (Organic Light-Emitting Diode, referred to as : OLED) has been gradually applied to display screens due to its low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. Quantum dots (Quantumdots, referred to as: QDs) luminescent material is a new technology used in the display field. The quantum dot luminescent material obeys the quantum size effect, and its properties change with the size of the quantum dot. When stimulated by light or electricity, the quantum dot luminescent material will emit colored li...
