Patent number: 10522107Abstract: A data driver includes shift registers, sampling latches, holding latches, and a data sensing unit. The shift registers generate sampling pulses by shifting a source start pulse in response to a source sampling clock. Each of the sampling latches receives current data and stores the current data in response to each of the sampling pulses. Each of the holding latches receives the current data stored in each of the sampling latches, and stores the received current data in response to a source output enable signal. The data sensing unit receives the current data corresponding to an i-th sampling latch of the sampling latches or an i-th holding latch of the holding latches (i is a positive integer) and previous data stored in the i-th sampling latch or the i-th holding latch, compares the current data with the previous data, and generates control data based on the comparison result.Type: GrantFiled: January 15, 2016Date of Patent: December 31, 2019Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Su Hyeong Park, Ho Yong Jung, Hoe Seok Na
