Accommodate a number of pixels in the panel manufacturer managed due to their small size - 11.5 mm x3. Recall the absolute record for the pixel density among all Android-devices today is the smartphone Samsung Galaxy S5 LTE-A 5.1-inch QHD-display - 576 ppi. Mass production of the new panels Sharp will begin only in 2016, respectively, and the first mobile news, equipped with them will be available no earlier than a year and a half.

Fixed voltage ( or Auto voltage selectable ) power supply circuit is used in this unit.  If Main Fuse (F601) is blown, check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply.  Otherwise it may cause some components in the power supply circuit to fail. BECAUSE A HOT CHASSIS GROUND IS PRESENT IN THE POWER SUPPLY CIRCUIT, AN ISOLATION TRANSFORMER MUST BE USED.  ALSO, IN ORDER TO HAVE THE ABILITY TO INCREASE THE INPUT SLOWLY, WHEN TROUBLESHOOTING THIS TYPE POWER SUPPLY CIRCUIT, A VARIABLE ISOLATION TRANSFORMER IS REQUIRED.
