5. The display apparatus according to claim 3, further comprising a power supply which supplies power, wherein

the first controller controls the power supply to cut off a supply of power if the main board module is disconnected from the display apparatus.

6. The display apparatus according to claim 1, wherein the first controller grants a control right to the first central processor to perform a predetermined control operation corresponding to a first event of a plurality of events, and grants the control right to the upgrading apparatus to perform a control operation corresponding to a second event of the plurality of events.

7. The display apparatus according to claim 6, wherein the first storage unit stores information regarding the control right corresponding to the plurality of events, and when a predetermined one of the plurality of events occurs, the first controller grants the control right corresponding to the predetermined event to one of the first central processor and the upgrading apparatus, based on the information regarding the control right stored in the first storage unit.

8. The display apparatus according to claim 7, wherein the upgrading apparatus stores information regarding the control right corresponding to the plurality of events, and

when the upgrading apparatus is connected to the display apparatus, the first controller receives the information regarding the control right which is stored in the upgrading apparatus and uses the received information to overwrite the information stored in the first storage unit.

9. The display apparatus according to claim 6, wherein at least one event of the plurality of events occurs when a predetermined signal is received from the outside.

10. The display apparatus according to claim 1, wherein the first controller checks whether the upgrading apparatus includes a microcomputer when the upgrading apparatus is connected to the display apparatus, grants the control right to the microcomputer of the upgrading apparatus to enable the upgrading apparatus if the upgrading apparatus includes the microcomputer, and transmits a system reset signal to enable the upgrading apparatus if the upgrading apparatus does not include the microcomputer.

11. The display apparatus according to claim 10, wherein the first controller comprises a connection detecting pin which is connected to a ground terminal and which detects a connection of the upgrading apparatus.

12. The display apparatus according to claim 11, wherein the first controller checks a connection status of the upgrading apparatus by using the connection detecting pin when power is applied, and determines whether to activate the display apparatus solely or to enable the upgrading apparatus, based on a result of the check.

13. The display apparatus according to claim 10, wherein the first controller comprises a microcomputer detecting pin which is used to check whether the upgrading apparatus includes the microcomputer.

14. The display apparatus according to claim 13, wherein the microcomputer detecting pin comprises a universal asynchronous receiver transmitter (UART) transmission pin which transmits a predetermined call signal to the upgrading apparatus and a UART reception pin which is configured to receive a response signal which corresponds to the predetermined call signal from the microcomputer included in the upgrading apparatus, and

the first controller checks whether the UART reception pin receives the response signal and uses a result of the check to determine whether the upgrading apparatus includes the microcomputer.

15. The display apparatus according to claim 14, wherein the controller comprises a general purpose input output (GPIO) pin, and

wherein the controller transmits, to the upgrading apparatus, a signal for granting the control right and the system reset signal by using the GPIO pin.
