3. A data processing device comprising:
-
(a) a display unit;
(b) a plurality of light-emitting units which illuminate said display unit;
(c) detector which detects whether a specific functional part in said data processing device is in operation or not; and
(d) a controller which controls a number of said light-emitting units to be turned on, when said detector has detected that said specific functional part in said data processing unit is in operation, and wherein said light emitting units, which are turned on, are independent of the location of the data to be displayed. - View Dependent Claims (4)
