A transmitter and a receiver are provided. The transmitter includes a processing unit configured to receive a clock signal and a data signal, set a value of a consecutive identical digit (CID) value related to the data signal and generate a modulation signal during a unit interval (UI) based on the data signal and the CID value, and a transmitter driver configured to output output signals having different voltage levels during the unit interval by receiving the modulation signal.

Data transmitting and receiving device

A method and circuit for controlling the brightness of a backlight in a display device. The circuit comprises a backlight brightness selecting block that measures the brightness of ambient light and selects brightness information of the backlight based on the measured brightness of the ambient light. An image processing block performs image processing on received image signal based on the measured brightness of the ambient light, and calculates an image processing gain of the received image signal based on the result of image processing and the received image signal. A backlight adjusting unit controls the brightness of the backlight based on the selected backlight brightness information and the image processing gain.
