Disclosed are a beam combining/splitting modulator, a display apparatus including the same, and a spatial light modulation method. The beam combining/splitting modulator includes a light modulator including first and second modulation regions for modulating light, a polarization converter disposed at a side of an emitting surface of the light modulator and including a first transmissive region for polarizing and converting light incident from the first modulation region to have a first polarization and a second transmissive region for polarizing and converting light incident from the second modulation region to have a second polarization, a birefringence modulator disposed at the side of an emitting surface of the polarization converter and switching between a first state in which birefringence occurs and a second state in which birefringence does not occur, and a polarizer disposed at the side of an emitting surface of the birefringence modulator.

Beam modulator and display apparatus using the same

Provided is an electro-phoresis device that includes a light control layer, a first electrode, a second electrode and a third electrode. The light control layer may include a plurality of electro-phoresis particles. The first electrode and the second electrode may form an electric field to control of the electro-phoresis particles such that the electro-phoresis particles move towards at least one of the electrodes. The third electrode may be electrically connected to any one of the first and second electrodes and may have an electric polarity opposite to the other of the first and second electrode.

Electro-phoresis device

Provided is a display device using electrochromism and methods of driving the same. The display device may include an electrochromic device, a plurality of first electrodes electrically connected to upper electrodes of the electrochromic device, and a plurality of second electrodes electrically connected to lower electrodes of the electrochromic device. By short-circuiting the first electrode and the second electrode, a desired pixel changes to reveal a predetermined or given color.
