Abstract: A method for preparing a fluorescent polarizing film based on directional arrangement of quantum rods. In the method, an inkjet printing technology is used for printing quantum-rod ink having proper viscosity and surface tension on a substrate according to a preset pattern, and directionally arranging quantum rods to obtain a fluorescent polarizing film. The diameter and spacing of fluorescent lines obtained by the method can be controlled and adjusted according to parameter conditions such as a needle aperture, a printing speed, and a preset pattern. The prepared transparent fluorescent film with directionally arranged quantum rods has a high degree of polarization, can be prepared on a flexible substrate in a normal temperature environment, and has wide applicability.

Abstract: Disclosed is a method for preparing a quantum rod/polymer fiber membrane by using electrospinning technique. The method comprises the following steps: (1) preparing a quantum rod solution; (2) preparing a polymer solution, and adding the quantum rod solution obtained in step (1) into the polymer solution so as to form an electrospinning precursor solution with a volume concentration of the quantum rods of 5%-80%; and (3) adding the electrospinning precursor solution into an electrospinning device, regulating the voltage of a generator and the receiving distance, and then performing electrospinning to prepare the quantum rod/polymer fiber membrane. By adjusting the concentration of the quantum rod solution and parameters in the electrospinning process, the method realizes directional arrangements of the quantum rods in the electrospinning process, thereby obtaining the quantum rod/polymer fiber membrane with high degree of polarization performance.

Abstract: Provided are a backlight module, a display device, a method for driving a display device, an electronic apparatus, and a computer-readable storage medium. The backlight module includes: a base substrate; multiple light emitting modules disposed on a side of the base substrate, where each of the multiple light emitting modules includes a first light emitting region, a second light emitting region and a third first light emitting region; and a light exiting layer disposed on a side of the light emitting modules facing away from the base substrate. Vertical projections of the first light emitting region, the second light emitting region and the third light emitting region on the base substrate overlap with vertical projections of a first light exiting region, a second light exiting region and a third light exiting region on the base substrate respectively. Each backlight driving module is connected to at least one light emitting module.
