Abstract
Disclosed herein are a display device capable of reducing the number of transmission lines by enabling a master circuit to perform communication with a plurality of slave circuits, which utilize different interfaces, through a common transmission line in a time divisional manner, and an interface method thereof. A timing controller uses a common transmission line of a gamma voltage generator and a level shifter which respectively utilize first and second interfaces and perform communication using the first and second interfaces in a time divisional manner.
Claims16
A display device, comprising:
- a timing controller;
- a gamma voltage generator connected to the timing controller through a common transmission line to communicate using a first interface in a first interface enable mode;
- and
- a level shifter connected to the timing controller through the common transmission line to communicate using a second interface in a second interface enable mode different from the first interface enable mode.
An interface method of a display device, the interface method comprising:
- communicating, by a timing controller using a first interface, with a gamma voltage generator connected through a common transmission line in a first interface enable mode to transmit gamma data;
- and
- communicating, by the timing controller using a second interface, with a level shifter connected through the common transmission line in a second interface enable mode to transmit a plurality of control signals.
