The present disclosure provides a film cutting method, a film cutting device, a composite film, a backlight module and a display device. The film material cutting method includes: using a cutting tool provided with a viscous material to cut a composite film that includes at least two laminated optical films, with the viscous material on the cutting tool being transferred to a cutting end surface of the composite film during cutting; and, curing the viscous material on the cutting end surface.

Film cutting method and cutting device, composite film, backlight module and display device

The present disclosure provides a display device, including: a light emitting device and a light adjusting layer, the light adjusting layer being on a light emitting side of the light emitting device, and the light emitting device being configured to generate and emit light having a wavelength in a wavelength range of visible light, wherein the light adjusting layer is configured to block light having a wavelength in a partial wavelength range of blue light from passing through when subjected to an external stimulus and allow the light having the wavelength in the partial wavelength range of blue light to pass through when the external stimulus is removed, and the light adjusting layer includes a responsive photonic crystal.

Display device, display system and display method

The embodiments of the present application provide a method and apparatus for adjusting color temperature of a display device. The method for adjusting color temperature includes establishing an initial set of color temperature relationship, wherein an element in the initial set of color temperature relationship at least comprises three components including a condition level value of a user, a color temperature value of the display device, and a fitness value of the user; determining an optimized set of color temperature relationship from the initial set of color temperature relationship, wherein a fitness value component of each element in the optimized set of color temperature relationship is within a first threshold range; detecting a condition level value of a current user; determining, from the optimized set of color temperature relationship, an element corresponding to the condition level value of the current user according to the detected condition level value of the current user; and adjusting the color temperature of the display device according to a color temperature value of the determined element.

Method and apparatus for adjusting color temperature of display device

The disclosure discloses a method and apparatus for adjusting color temperature based upon fuzzy control. The method for adjusting color temperature based upon fuzzy control includes: determining an initial color temperature value of a screen of an terminal device according to an illumination intensity of ambient light when the screen is lightened; obtaining a percentage of eyelid closure over the pupil, over time, PERCLOS of a user, and the illumination intensity of ambient light at a preset periodicity; and determining a target color temperature value corresponding to the current PERCLOS of the user, and the current illumination intensity of ambient light according to a preset fuzzy rule, and adjusting the screen to the target color temperature value, wherein taking the PERCLOS, and the illumination intensity of ambient light as input signals, and the color temperature as an output signal according to the preset fuzzy rule.
