Embodiment Construction

[0027] The technical solutions of the present invention will be clearly and completely described below, and obviously, the described embodiments are part 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 making creative efforts belong to the protection scope of the present invention.

[0028] figure 1 It is a structural schematic diagram of a display panel in the prior art, including a substrate 1, a blue light chip 2 disposed on the substrate, and a light conversion layer 3 arranged along the light emitting direction of the blue light chip, and the light conversion layer 3 includes a red light conversion layer and a green light conversion layer , after the blue light emitted by the blue chip passes through the red light conversion layer and the green light conversion layer, it emits red light and green light respectively. The tradition...

Abstract

The invention provides a display panel. The display panel comprises a substrate; a plurality of pixel units arranged on the substrate, wherein each pixel unit comprises a first sub-pixel, a second sub-pixel and a third sub-pixel, and the second sub-pixel and / or the third sub-pixel includes a light conversion layer that converts light of one color into light of another color. The light conversion layer includes a nano-metal composite structure. The local surface plasmon polariton resonance effect of metal in the light conversion layer is utilized, so the intensity of fluorescence peaks in sub-pixels is enhanced, blue light peaks disappear, and the overall color gamut of the display panel is improved.

Description

technical field [0001] The invention belongs to the field of displays, and in particular relates to a display panel and a display device. Background technique [0002] At present, there are usually two ways to generate sub-pixel RGB light sources in display panels. One is to make red, green, and blue light-emitting chips separately, and form a color light source by mixing the three chips; the other is to use blue lasers. The light source is matched with the light conversion layer to generate red and green light sources, which are then mixed with blue light to form light of various colors. The second production method is widely used because of its low cost and simple process. However, in the prior art, the light conversion layer cannot absorb all the blue light excitation light sources, resulting in each red / green sub-pixel emitting red / green light accompanied by a certain proportion of blue light, resulting in a reduced color gamut. Contents of the invention [0003] The...
