“…Laser illumination, especially the direct green laser, will improve many characteristics of the LCOS pico-projectors and truly enable dramatic improvements in efficiency, cost, and performance. In addition, the potential for Laser+LCOS technology to enable ultra-green high definition television is promising [5].…”

The progress in digital high resolution, small pixel liquid crystal on silicon (LCOS) microdisplays will be discussed and how it will lead to HD displays in very small form factors. The first generation of this technology is enabling very small yet high resolution projection engines devices that can be embedded in cell phones, cameras, head-mount displays, and set-top boxes and the next generation will bring HD resolution. As lasers become more affordable we see this LCOS display technology fundamentally changing the power consumption, cost, and size of pico-projectors and other display devices. One of the most interesting conclusions is that by using LCOS technology in combination with lasers, it should soon be possible to build an “ultra-green” television that would consume less than 1/8th the power of equivalent size LCD flat panel TV.

“…Typical LED pico-projectors have a throw ratio (image diagonal: distance to the screen) from about 1:1 to 0.5:1. 28 Because laser light has a higher fnumber, it will be possible to make very short throw optical engines 29,30 with throw ratios on the order of 5:1 and with 100% offset (relative to the projected plane). This means that an engine only ~3 in.…”

The advent of affordable direct-diode lasers changes all the rules for optical designs and the associated technologies that generate the images from laser light. These new lasers are forseen as driving fundamental changes in the size, power consumption, cost, resolution, and even the uses for pico-projectors. This paper discusses these topics from the perspective of laser-light-illuminated LCOS microdisplays.

“…However, these systems are often expensive and bulky and are ill-suited for integrated devices [3,[8][9][10]. Semiconductor laser diodes are compacts but the heterogeneous integration of several wavelengths comes with a high cost and it is still difficult to access certain wavelengths like in the green-orange region of the visible [11].…”

RGB and white-emitting organic lasers on flexible glass

et al. 2016

Two formats of multiwavelength red, green and blue (RGB) laser on mechanically-flexible glass are demonstrated. In both cases, three all-organic, vertically-emitting distributed feedback (DFB) lasers are assembled onto a common ultra-thin glass membrane substrate and fully encapsulated by a thin polymer overlayer and an additional 50 µm-thick glass membrane in order to improve the performance. The first device format has the three DFB lasers sitting next to each other on the glass substrate. The DFB lasers are simultaneously excited by a single overlapping optical pump, emitting spatially separated red, green and blue laser output with individual thresholds of, respectively, 28 µJ/cm(2), 11 µJ/cm(2) and 32 µJ/cm(2) (for 5 ns pump pulses). The second device format has the three DFB lasers, respectively the red, green and blue laser, vertically stacked onto the flexible glass. This device format emits a white laser output for an optical pump fluence above 42 µJ/cm(2).
