An anonymous reader writes: Will pico-projectors become standard equipment on mobile phones, the same way that digital cameras have become? The jury is still out on user acceptance--after all only four mobile phones use pico-projectors today--but if they get small and cheap enough, mobile phone makers are going to install them. There are four vendors today--Microvision, National Semiconductor, 3M and Texas Instruments, but only TI has design wins in cell phones already on the market. And at the recent Mobile World Congress, TI showed a smaller digital light processor (DLP) chip that fits inside even the slimmest mobile phones, and which it claims is cheap enough to become standard equipment. A lot of us never use the camera in our phones now--would you use a pico-projector if it was built into your phone?
