Abstract: Disclosed are a source driver for sensing the degree of deterioration in pixels in some regions of a display panel and compensating for the deterioration in the display panel based on the sensed degree, by considering a characteristic in which pixels included in each display panel similarly deteriorate, and a display device including the same. The display device may include a display panel including pixels, a sensing circuit configured to provide sensing data by sensing the degree of deterioration in pixels in at least one first region of the display panel, and a compensation circuit configured to calculate an amount of compensation of each of the pixels in the first region using the sensing data and compensate for the deterioration in the pixels in the first region and pixels in a second region whose degree of deterioration is not sensed, based on the amount of compensation.

Abstract: Disclosed is a system for transmitting and receiving safety information, which generates first safety information about a control target and second safety information representing the occurrence or not of an error in the control target by using one microcontroller. The system includes a first slave controller generating first safety information and second safety information by using sensing data obtained from a control target and a master controller receiving the first safety information and the second safety information from the first slave controller through a wireless channel. When an error occurs in the first slave controller, the first slave controller transmits the second safety information to a second slave controller, and the second slave controller transmits the second safety information, received from the first slave controller, to the master controller.
