Abstract: A liquid crystal electronic curtain is disclosed. The liquid crystal electronic curtain includes a liquid crystal layer between first and second substrates. The curtain also includes a polarizer on one of a side of the first substrate away from the second substrate, and a side of the second substrate away from the first substrate. The curtain also includes a first electrode layer on a side of the first substrate facing the second substrate. The first electrode layer includes touch display units, and first electrode leads, each connected with one of the touch display units. The touch display units are connected with detection circuits via the first electrode leads. The curtain also includes a second electrode layer disposed on a side of the second substrate facing the first substrate, a driving circuit, and a second electrode lead, where the driving circuit is connected with the second electrode lead.

Abstract: A dichromatic dye composition which has the characteristics of higher order parameter and good miscibility can be applied in a guest-host liquid crystal composition. The absorbance curve of a guest-host liquid crystal composition with the dichromatic dye composition within the range of 420-680 nm has the following characteristics: a. 2?(T1+T2)/?T?10; b. |T1?T2|?0.5; c. 0<?T?0.2, where T1 is a difference between a transmittance to light at 420 nm and a minimum transmittance, T2 is a difference between the transmittance at a wavelength of 680 nm and a minimum transmittance, and ?T is a difference between the maximum and minimum transmittances on the transmittance curve within the wavelength range of 420-680 nm. A liquid crystal element with the guest-host liquid crystal composition provides a high-contrast display. A liquid crystal display device has the guest-host liquid crystal composition with the dichromatic dye composition.
