Embodiment Construction

[0024] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the invention may be practiced. The directional terms mentioned in the present invention, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are only for reference The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In the figures, structurally similar elements are denoted by the same reference numerals.

[0025] The present invention is aimed at the existing existing quantum dot liquid crystal displays. When the quantum dot film layer is attached to the polarizing layer or the color filter layer, due to the low excitation efficiency, it is difficult to achieve the ideal high color gamut, wide viewing angle, The requirement of high energy efficiency further leads to the ...

Abstract

A quantum dot liquid crystal display, comprising a liquid crystal display panel (10) and a backlight module (20). The liquid crystal display panel (10) comprises a first quantum dot film layer (11), and the backlight module (20) comprises a second quantum dot film layer (22); the relation between the film thickness y of the second quantum dot film layer (22) and the film thickness x of the first quantum dot film layer (11) is: y=0.264 / T2*x2-0.9312x+T1.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot liquid crystal display. Background technique [0002] At present, due to the excellent properties of high color purity and continuous adjustable spectrum of quantum dot materials (Quantum Dot, QD) itself, it has become the most excellent luminescent material in the 21st century, which can greatly improve the display color gamut of existing LCDs. Color performance, so its display applications have been widely studied in recent years. The existing QD-OC (quantum dot liquid crystal display panel) has the advantages of extremely large viewing angle and high color gamut. The viewing angle of mass-produced ordinary LCD TVs sold in the existing market is about 60°, and the viewing angle of quantum dot TVs is about 80°. In the existing technology, the quantum dot film layer is introduced into the polarizing layer on the side of the TFT array substrate, and it is pasted o...
