ABSTRACT:
In a control board and a display apparatus, the control board includes a timing controller, and first and second connectors. The timing controller receives a first external image control signal having one of a first and a second frequency, and selectively receives a second external image control signal having the first frequency when the first external image control signal has the first frequency. The timing controller selects one of the first and second frequencies based on the first and second external image control signals to output an image driving signal. The first connector connects the timing controller to an external video system to transfer the first external image control signal to the timing controller. The second connector connects the timing controller to the external video system to transfer the second external image control signal to the timing controller. Thus, the control board is commonly used in the first and second frequencies.
