handphone hinge technology

technology mobile menyplay digital interfaces (mddi) designeds special to run fitur multimedia in handphone berdesain besides candy pothouse.

design candy pothouse till now still to dominate handphone model besides desian another likes flip or clamshell. various handphone even also now present with assortedly design more interesting. begin from slidding, swing, rotating menyplay up to pop up menyplay.

handphone design besides candy has special characteristic between sail and keypad apart or doesn't stay in one part. for vendor design handphone will like this of course more complex in will make it. or can can production cost increase, because must prepare addition component that is cable that connect sail part with part keypad.

now present standard newest technology to has connected sail part and keypad in handphone apart, the name mobile menyplay digital interfaces (mddi). mddi developed qualcom. this technology is mengintegrasikan into chipset product qualcom for ware moves. especially ware that use technology cdma and wcdma. mddi begin made in chipset qualcom with series msm6150 and msm6550 for technology cdma2000 and msm6275 and msm6280 for technology wcdma. likely technology mddi this is special is developed to support future cellular technology.

mddi has several superiorities is compared previous technology. mengantaranya that is economicaler in battery power consumption, can mensupport sail lcd of the size qvga and also can mensuport camera with sharpness 1 megapixel up to 3 megapixel. ability mddi not only can to controls one sail, but also can controls two sails all at once (internal and external). and there one another superiority that be mainstay from this technology that is can to decrease cable that rush by between sail part and keypad. previous wanted 21 cables, now only five cables. with work system two cables haves to transfer data, two cables functioneds as synchronization between sail and keypad as controller and one cable again functioned to channel power. with this cable total reduction existence, of course sagat be of benefit to side vendor, because can to decrease production cost.

although mddi only want five cables but doesn't decrease the transfer speed. even this technology belongs to to into technology that can to transfer data in high-speed. because mddi can to transfer data according to bi-directional with capacity bandwith maximum 3,2 gigabits per second. that way so various fitur multimedia with big capacity, 3g for example gamete, permanent can be enjoyed comfortably. while more sophisticateder fitur that run in ware with sail design and keypad apart, so total kebel that wanted to transfer data between part keypad and sail more and more.

several vendor begin mengaplikasi technology mddi this, mengantaranya that is samsung and sharp. vesa (video elctronics standards association), that is world organization that have as member more than 110 company electronics, also mensupport this newest technology standard existence. to the fore it mddi apparently not only mengimplementasikan in handphone. but also can mengimplementasikan in another ware like laptop, pocket pc (pda) and another.
