Abstract

The invention provides a display device with a quantum dot diaphragm. The display device with the quantum dot diaphragm comprises a display panel, a backlight module (2) located below the display panel, the quantum dot diaphragm (3) located between the display panel and the backlight module (2), and a plurality of light reflecting units (41) arranged between the quantum dot diaphragm (3) and the display panel. The quantum dot diaphragm (3) emits exciting light under excitation of the backlight module (2). A black matrix is arranged in a liquid crystal panel. The light reflecting units (4) correspond to the black matrix. The display device with the quantum dot diaphragm is wide in color gamut range, good in image quality and high in quantum dot excitation efficiency and backlight utilizing efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device using a quantum dot membrane. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for display quality of display devices. Currently, LCD TVs on the market can display a color gamut between 68% and 72% NTSC (National Television Standards Committee), so they cannot provide high-quality color effects. In order to improve the performance color gamut of LCD TVs, high color gamut backlight technology is becoming the focus of research in the industry. [0003] Quantum dot material (QuantumDots, referred to as QDs) refers to semiconductor grains with a particle size of 1-100nm. Due to the small particle size of QDs, which is smaller than or close to the exciton Bohr radius of the corresponding bulk material, a quantum confinement effect occurs, and the continuous energy band structure of the b...
