Laser beam scanned display apparatus and method thereof
View Patent ↗Generally, near seamless electronics displays may be employed in cinema and exhibition applications. Laser scanned displays may be enabled such that the display may display three dimensional (“3D”) content. A first method to enable a laser scanned display for 3D content may employ polarization, with or without polarization conversion and another method may employ multiple colors. Additionally, the envelope function that may be employed across the display may be achieved by changing laser power as a beam is scanned on the screen or by changing the dwell time of the laser beam on the pixels. One method of minimizing the effects of seams in the screen may be to reduce the screen resolution near the seams by screen design and/or laser beam dwell time or illumination energy.
1. A display system, comprising:
a light source operable to scan with a beam and further operable to produce light energy;
at least a first substrate and a second substrate joined together to form the appearance of a seam and operable to receive light from the light source;
a first phosphor layer proximate to the first substrate and a second phosphor layer proximate to the second substrate and operable to transmit light for images; and
wherein the light source comprises an array of light engines, wherein the first substrate is substantially illuminated by at least an individual light engine of the array of light engines to generate a substantially seamless appearance.
2. The display system of claim 1 , further comprising a wavelength selective mirror proximate to the first phosphor layer.
3. The display system of claim 1 , further comprising:
a polarizer layer operable to receive at least some light from the phosphor layer; and
a film patterned retarder layer operable to receive at least some light from the polarizer layer.
4. The display system of claim 3 , further comprising a diffuser layer operable to receive at least some light from the film patterned retarder layer.
5. The display system of claim 3 , further comprising a wavelength selective mirror proximate to the first phosphor layer.
6. The display system of claim 5 , wherein the wavelength selective mirror is operable to substantially reflect RGB light and to substantially transmit light at approximately 405 nanometers.
7. The display system of claim 2 , wherein the wavelength selective mirror is operable to substantially reflect RGB light and to substantially transmit light at approximately 405 nanometers.
