Embodiment Construction

[0024] Embodiments of the present invention provide a method for manufacturing a color liquid crystal film, a color liquid crystal film, and a display device. A blue phase liquid crystal stabilized by a polymer is used to manufacture a color liquid crystal film, and an electric field is used to twist the liquid crystal to realize display of different colors. The liquid crystal is fixed by irradiation with ultraviolet light. Since the liquid crystal is twisted by the electric field, and the control of the electric field strength is much easier than the temperature control, it can improve the production efficiency of the color liquid crystal film, and it is also easy to control the color presented by the color liquid crystal film. In addition, by applying electric fields of different intensities, it is possible to fabricate colored liquid crystal films with a wide variety of colors.

[0025] Such as Figure 4 As shown, the manufacturing method of the color liquid crystal film p...

Abstract

The invention discloses a method for manufacturing color liquid crystal films, a color liquid crystal film and a display device, which belong to a liquid crystal display technology. A color liquid crystal film is manufactured by using stable-polymer blue-phase liquid crystals, and the liquid crystals are twisted through electric fields so as to realize the displaying of different colors, and then the liquid crystals are fixed through ultraviolet irradiation. Because the liquid crystals are twisted through electric fields, and the control on the intensities of the electric fields is much easier than the control on temperature, the manufacturing efficiency of the color liquid crystal film can be improved, and the represented color of the color liquid crystal film is controlled easily; and meanwhile, a color liquid crystal film which is rich in color types can be manufactured through exerting electric fields with different intensities.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a manufacturing method of a color liquid crystal film, a color liquid crystal film and a display device. Background technique [0002] At present, the technology of flexible display is becoming more and more perfect. Most of the color liquid crystal films in flexible display devices are made of cholesteric liquid crystals. The method of manufacturing color liquid crystal films through cholesteric liquid crystals is as follows: figure 1 shown, including: [0003] Step S101, controlling the temperature at a first temperature so that the liquid crystal film appears red, and the first temperature is about 25 degrees Celsius; [0004] Step S102, irradiating the area to be made red with ultraviolet light, and fixing the liquid crystal in this area, such as figure 2 shown; [0005] Step S103 , controlling the temperature at a second temperature, so that the region where the liq...
