Mobile phone in a box = video projector?
Cheapo no-name/rebadgeable chinese video projector. Uses really only an
analogue IC to process baseband video and sound, and mainly a TSUMV56RBUT-Z1 processor (LCD driver+ more) , only info in chinese. But mention of Android OS emerges in the otherwise chinese script. So is it just a mobile phone LCD display in a box , changed firmware to handle HDMI and SVGA inputs,rejigged pcb, plus high power LED floodlamp instead of backlight, compound lens, mirror,2 fresnels , one pivoted for keystone, and a radial fan for relative quietness, and a small speaker? |
