Armstrong Teasdale LLP
Display device and method for controlling display device
A display device and a method for controlling the display device are disclosed. The display device includes a backlight module and a liquid crystal cell on a light emitting side of the backlight module. The liquid crystal cell includes a first electrode, a second electrode disposed in a first direction opposite to the first electrode, a liquid crystal layer between the first electrode and the second electrode, and a diffractive optical element in the liquid crystal layer. A refractive index of the diffractive optical element is equal to a short-axis refractive index of a liquid crystal in the liquid crystal layer. The liquid crystal cell is divided into a first portion where the liquid crystal molecules are capable of rotating in a first plane and a second portion in a second direction perpendicular to the first direction where liquid crystal molecules are capable of rotating in a first plane.
