Apparatus and method for setting an ID code using a microcomputer in a display device

摘要

An apparatus in a display system for setting an ID password includes a microprocessor, an input device and an output device. The input device incorporates an array of user manipulated keys so as to allow a user to input an ID code to the microprocessor. The microprocessor includes a program for comparing an inputted ID code with preset ID data stored in a memory to determine consistency therebetween. The microprocessor further includes a program for displaying information visually to a user and so as to allow only an authorized user to use the display thereby protecting private confidential information from misuse. A method for implementing the ID password system includes generally the steps of inputting an ID code via an input device, comparing an inputted ID code with a preset data stored in a memory and thereby controlling the display. As a result, a display employing an embodiment of the present invention may be used by an authorized user only.
