2 Unit Description of EF81
The EF81 is a clam shell phone with two displays for closed and open mode usability. The camera is
mounted inside the hinge and facing towards the user when the phone is opened (e.g. for video
conferencing, self portraits or self videos). In closed mode the camera can be used for photo and
video recording, using the 2 nd display as a viewfinder. The camera picture format is usually fitting to
display size, so that the phone has to be e.g. held vertical for landscape photo and video recording.
Only during video telephony, there will be two landscape screens (far end and viewfinder) at the
inside portrait display.
The phone has two different acoustic modules one for receiver mode inside and one for sound
ringer and hands free mode with separate holes on front outside.
The exchangeable TransFlash card reader and SIM reader (both are push-push-reader) could be
reached after removing the battery cover. The readers are soldered on an additional PCB (PCB-
Card) which is stacked in the Base Upper Case. The 3 layers Main-FPC is lying on top of the PCB-
Card and Base Upper Case and beneath the slim keypad. The Main-FPC is populated with the
metal dome foil for keypad functions and EL-foil for lightening, step-inverter, hall-sensor and B2B-
Connector for connecting Display, Camera and Top-keys. The ultra slim keypad is out of a metal
sheet with co-moulded silicone.
There are no side keys, but 4 soft keys (1 rocker and 2 single) below the outside display (Top-keys).
There will be one colour variant, silver/black. The Top Cover of the Flip-Part is made of brushed
stainless steel with an integrated real glass for the 2 nd display lens. The lower level of the Base-Part
(Base Lower Case) is painted in matt black and the Battery cover is matt-black anodized (eloxated)
to get a smaller impression.
