Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0031] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only relative concepts or refer to the normal use state of the product, and should not be regarded as limiti...

Abstract

The invention relates to the technical field of displaying, and provides a quantum-dot color film substrate, a manufacturing method thereof and a display device.According to the manufacturing method of the quantum-dot color film substrate, as the half-exposure technology is adopted for different regions in the later working procedure, a color film is finally prepared only through one yellow light manufacturing procedure of sequential coating of green-light quantum-dot films and red-light quantum-dot films; compared with the existing technology, one yellow light manufacturing procedure is omitted, the manufacturing technology is simplified, and manufacturing cost is saved; in addition, when the quantum-dot color film substrate is applied to the display device, blue backlight is completely converted by the green-light quantum-dot films in a green sub-pixel region into green light, blue backlight is converted by the green-light quantum-dot films in a red sub-pixel region into green light which is then converted into red light through the red-light quantum-dot films, and the use rate of the blue backlight is up to 100%.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, relates to a quantum dot color film substrate, a manufacturing method thereof, and a display device. Background technique [0002] In the contemporary information society, the importance of displays as a visual information transmission medium is gradually increasing. In order to dominate in the future, displays are trending toward lighter, thinner, lower power consumption, lower cost, and better image quality. [0003] Currently, the color gamut of LCD TVs on the market is between 68-72% NTSC, which cannot provide high-quality display effects. Therefore, improving the color gamut of LCD TVs has become the focus of research in the industry. Quantum dot materials refer to inorganic semiconductor nanocrystals with a particle size between 1-100nm. Because electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy-level str...
