Embodiment 1

[0052] Such as figure 1 As shown, this embodiment provides a color filter, including a plurality of pixels, each pixel includes a number of color sub-pixels of different colors, and the color filter also includes:

[0053] Base substrate 11, the base substrate can be any transparent material such as glass substrate, quartz, resin;

[0054] Wherein, at least one color sub-pixel is formed of a quantum dot material, and the light generated after the quantum dot material is excited is the same color as the corresponding color sub-pixel;

[0055] The filter layer 12 is arranged in the color sub-pixel area formed by the quantum dot material, and is used for absorbing the light that does not excite the quantum dot material.

[0056] The color sub-pixel in this embodiment includes a red sub-pixel 14R, a green sub-pixel 14G and a blue sub-pixel 14B, the red sub-pixel 14R is formed of red quantum dot material, and the green sub-pixel 14G is formed of green quantum dot material; The blue...

Embodiment 2

[0064] Such as image 3 As shown, this embodiment provides a display device, which includes the color filter 10 in Embodiment 1, and also includes an array substrate 20 and a backlight 40 . A liquid crystal layer 30 is disposed between the color filter 10 and the array substrate 20 to form a liquid crystal panel. Wherein, the backlight 40 is an ultraviolet backlight. In the color filter 10, the red sub-pixel 14R is formed of a red quantum dot material, the green sub-pixel 14G is formed of a green quantum dot material, and the blue sub-pixel 14B is formed of a blue quantum dot material, and each color sub-pixel area is provided with The filter layer 12 is used for absorbing ultraviolet light 80 .

[0065] It should be noted that the light from the ultraviolet backlight in this embodiment first passes through the colored sub-pixels formed by the quantum dot material, the ultraviolet light excites the quantum dot material to emit light of the corresponding color, and the ultrav...

Embodiment 3

[0069] Such as Figure 4 As shown, this embodiment provides a color filter, including a plurality of pixels, each pixel includes a number of color sub-pixels of different colors, and the color filter also includes:

[0070] Base substrate 11, the base substrate can be any transparent material such as glass substrate, quartz, resin;

[0071] Wherein, at least one color sub-pixel is formed of a quantum dot material, and the light generated after the quantum dot material is excited is the same color as the corresponding color sub-pixel;

[0072] The filter layer 12 is arranged in the color sub-pixel area formed by the quantum dot material, and is used for absorbing the light that does not excite the quantum dot material.

[0073] The color sub-pixel in this embodiment includes a red sub-pixel 14R, a green sub-pixel 14G and a blue sub-pixel 14B, the red sub-pixel 14R is formed of red quantum dot material, and the green sub-pixel 14G is formed of green quantum dot material; The b...

Abstract

The invention relates to the technical field of displaying, in particular to a quantum dot color filter, a manufacturing method thereof and a display device. The quantum dot color filter comprises a plurality of pixels, a substrate and a filter layer, wherein each pixel comprises a plurality of color sub-pixels in different colors; at least one color sub-pixel is formed by a quantum dot material; the color of light generated by exciting the quantum dot material is the same as that of a corresponding color sub-pixel; and the filter layer is used for absorbing light rays of the non-excited quantum dot material. The color filter is formed since quantum dots can present physical features of fluorescent light of different colors under the irradiation of a backlight source, so that the transmittance of the color filter is increased, the brightness and colors of pictures are improved and enriched greatly, the display quality of images is improved, the user experience is enhanced, and meanwhile, the production cost is reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot color filter, a manufacturing method thereof, and a display device including the quantum dot color filter. Background technique [0002] In recent years, with the development of science and technology, liquid crystal display technology has also been continuously improved. TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor-Liquid Crystal Display) occupies an important position in the display field due to its advantages of good image display quality, low energy consumption, and environmental protection, but its color is difficult to cover completely color gamut. The display technology based on organic light-emitting diode (OLED), which has emerged in recent years, is also becoming more and more mature. It has a simple structure, thin thickness, fast response speed, and can achieve richer colors. At the same time, with the birth ...
