Abstract
A display device includes a display unit, a driving unit, a control board, and at least one recovery unit. The display unit includes a plurality of pixels. The driving unit provides a driving signal to the display unit. The control board is spaced apart from the driving unit and outputs the output signal in a serial link manner. At least one recovery unit is located between the driving unit and the control board and is spaced apart from the driving unit and the control board, and is configured to recover the output signal.
Claims14
A display device, comprising:
- a display unit including a plurality of pixels;
- a driving unit configured to provide a driving signal to the display unit;
- a control board which is spaced apart from the driving unit and is configured to output an output signal in a serial link manner;
- at least one recovery unit which is located between the driving unit and the control board, is spaced apart from the driving unit and the control board, and is configured to recover the output signal received from the control board,
- wherein the recovery unit includes:
- an equalizer configured to remove a noise component generated in the output signal during transmission to the recovery unit and configured to recover a signal level of the output signal received from the control board from which the noise component has been removed to provide an equalized signal, and
- a pre-emphasis circuit configured to modify a waveform of the equalized signal by adjusting a specific bit of the equalized signal to output a recovered output signal;
- a first coaxial cable connected between the recovery unit and the control board;
- and
- a second coaxial cable connected between the recovery unit and the driving unit.

A display device, comprising:
- a display unit including a plurality of pixels;
- a source board configured to provide a driving signal to the display unit;
- a control board which is spaced apart from the source board and is configured to output an output signal in a serial link manner;
- and
- a cable assembly configured to connect the source board and the control board to each other, recover the output signal between the source board and the control board to generate a recovery signal, and transmit the recovery signal to the source board,
- wherein the cable assembly includes a recovery unit embedded therein, the recovery unit being configured to recover the output signal received from the control board, and
- wherein the recovery unit includes:
- an equalizer configured to remove a noise component generated in the output signal during transmission to the recovery unit and configured to recover a signal level of the output signal received from the control board from which the noise component has been removed to provide an equalized signal, and
- a pre-emphasis circuit configured to modify a waveform of the equalized signal by adjusting a specific bit of the equalized signal to output the recovery signal;
- wherein the cable assembly further includes a first coaxial cable connected between the recovery unit and the control board, and a second coaxial cable connected between the recovery unit and the source board.
