Smart speakers are becoming a common fixture in households as consumers continue to adopt smart home solutions. With on-demand virtual assistants and quality audio performance, incorporating display functionality is a logical next step for these “out all of the time” devices.
The first generation of smart displays incorporate relatively small 7-10” screens. Bigger screens, for example 15-40”, would be helpful for viewing from farther distances. However, larger flat panel displays would lead to larger smart displays that may grow too big for areas with limited space, like a kitchen counter top or a side table, or too bulky to be aesthetically pleasing. A solution to this problem is pico projection – it can enable large, on-demand displays from small devices.
TI DLP® Pico technology enables small, high-performance, low-power projection smart display solutions. A DLP Pico digital micromirror device (DMD), with up to millions of micromirrors, creates the image in sync with color-sequential illumination. A DLP controller on a nearby PCB accepts incoming video via a MIPI DSI or parallel RGB interface from a processor.
For the smallest display systems, DLP Pico chipsets that include a 0.2”-class micromirror array diagonal are recommended. These solutions enable extremely compact optical systems and the lowest possible power consumption, while 0.3” chipsets offer higher brightness.
