Abstract
A display has reduced moire interference. The display has a backplane with a regular array of pixels and a frontplane with a regular array of cells. The backplane and frontplane are laminated together. The width of the distribution of aperture (the total inner cell area above an active pixel area divided by total pixel area) over the display is reduced. Sinusoidally curved walls or other curved pixel edges may be used in the frontplane or backplane to control the distribution.
Claims17
A display comprising:
- a backplane having an array of electronic pixels, two or more electronic pixels of the array of electronic pixels each having an active pixel area and a total pixel area;
- and
- a frontplane comprising an array of electro-optic elements,
- the frontplane being fixed to the backplane,
- the active pixel areas of at least two of the two or more electronic pixels in the backplane being opposite respective inner cell areas of a corresponding at least two of the two or more electro-optic elements and forming at least respective first and second display elements of the display,
- the first and second display elements each having an aperture, and
- the aperture of the first display element having a predetermined value different from the aperture of the second display element,
- wherein one or more of the electronic pixels has all curved edges or all jagged edges.
A method of manufacture of a display comprising:
- providing a backplane having an array of electronic pixels;
- and
- determining a desired geometry for a frontplane having an array of opto-electronic pixel elements, the desired geometry having a reduced aperture with respect to a value of aperture in a display in which cells of the opto-electronic pixel elements are rectangular in shape and substantially symmetrical with cells of the electronic pixels,
- wherein one or more of the electronic pixels has all curved edges or all jagged edges.
A method of designing a display screen comprising:
- determining a variation in aperture of pixels of two or more possible pixel arrays for the display screen;
- and
- choosing for the display screen a one of the two or more possible pixel arrays, the one of the two or more possible pixel arrays chosen having a relative width of aperture less than a second of the two or more possible pixel arrays,
- wherein one or more of the pixels has all curved edges or all jagged edges.
