Abstract

The invention provides a display panel and an optical sheet applying the same. The optical sheet comprises a substrate layer, a light shielding layer, a color light-filtering structure, a scattering layer and a first reflection layer. The light shielding layer is located on the substrate layer. Additionally, the light shielding layer has multiple openings. The color light-filtering structure is installed in at least a part of openings. Additionally, the color light-filtering structure comprises multiple quantum dots. The scattering layer is arranged between the color light-filtering structureand the first reflection layer. The first reflection layer is arranged between the color light-filtering structure and the light shielding layer. Accordingly, the likelihood of activation of the quantum dots is increased through the scattering layer and the first reflection layer. Therefore, light conversion efficiency of the display panel is improved.

Description

technical field [0001] The present invention relates to a quantum dot display technology, in particular to a display panel and an optical sheet used therefor. Background technique [0002] Due to its good optical properties, quantum dot display technology has recently been widely used in various electronic devices with display screens, such as smart phones, tablet computers, notebook computers, and LCD TVs. For quantum dot display technology, the display panel is additionally provided with a quantum dot enhancement film with multiple color quantum dots between the backlight module and a color filter (quantum dot color filter, QDCF), or a quantum dot color filter The filter replaces the traditional color filter. [0003] For the quantum dot color filter, the color filter structure has quantum dots, and the quantum dots can be excited by light incident on the color filter structure to emit light of a specific color. However, a part of the light incident on the color filter s...
