Factory mode free setting apparatus and method thereof
First Claim
1. An apparatus for setting factory mode of operation in a display apparatus, comprising:
- an external controller disposed outside of said display apparatus, having a keyboard, an external microprocessor connected to said keyboard and receiving modified factory mode data from said keyboard, and an external memory connected to said external microprocessor and receiving and storing said modified factory mode data from said external microprocessor;
a main microprocessor disposed within said display apparatus, connected to said external microprocessor and receiving said modified factory mode data transmitted from said external controller;
a main memory disposed within said display apparatus, connected to said main microprocessor, having a factory mode address and a user mode address, storing initial factory mode data in said factory mode address and user mode data in said user mode address, deleting said initial factory mode data and storing said modified factory mode data received from said external controller into said factory mode address; and
a video stage coupled to said main microprocessor, receiving one of said modified factory mode data and said user mode data, driving a screen representing said one of said modified factory mode data and said user mode data.

Abstract
A technique for collectively setting a factory mode of operation of a monitor offers adjustments or modifications for particulars of mode data to meet user requirements, by transmitting a set of factory mode timing data from an external controller to an electrically erasable programmable read only memory using a serial interface data communication. A factory mode data transmission process includes the steps of transmitting a start data signal to a microcomputer in a monitor when a storage key input is fed to the external controller, repeatedly sending the timing data until a mode end signal is input and sending a mode end data to the microcomputer when a mode end signal is input. In addition, a factory mode data receiving process includes the steps of sending back the start data received to the external controller, storing mode timing data received into a factory mode address reserved in a memory in the monitor and ending the reception of mode timing data when mode end data is inputted. Consequently, any operation mode according to user requirements is able to be set in a monitor, without modifying a pre-installed program in a microcomputer housed therein, at a low cost.
