Samsung patents 3D display using dithering to adjust color depth
Samsung describes a display system that uses a special film to create a 3D effect without requiring glasses. The device uses a technique called dithering, which rapidly switches pixels on and off, to simulate different shades of gray for each viewing angle.
In the filing’s own words
Provided is a display apparatus including a display including a plurality of pixels included in a pixel column unit, the plurality of pixels being configured to be driven based on electrophoretic process, a three-dimensional film including a plurality of refractive regions and on a plurality of pixel columns of the display, memory configured to store instructions, and one or more processors including processing circuitry, when executing the instructions, is configured to cause the display apparatus to perform dithering in units of a plurality of pixels consecutively included in each pixel column of the plurality of pixel columns to adjust grayscale for each view of a plurality of views.
What exactly they claim (claim 1)
1. A display apparatus comprising: a display comprising a plurality of pixels included in a pixel column unit, the plurality of pixels being configured to be driven based on electrophoretic method; a three-dimensional film comprising a plurality of refractive regions and on a plurality of pixel columns of the display; memory configured to store instructions; and one or more processors comprising processing circuitry, when executing the instructions, is configured to cause the display apparatus to: perform dithering in units of a plurality of pixels consecutively included in each pixel column of the plurality of pixel columns to adjust grayscale for each view of a plurality of views.
