DISPLAY DEVICE CAPABLE OF RESTORING A DELAYED LOW VOLTAGE DIFFERENTIAL SIGNAL BY BEING SYNCHRONIZED WITH A CLOCK FOR RESTORING DATA, AND A DIFFERENTIAL SIGNAL RECEIVING METHOD THEREOF

摘要

PURPOSE: A display device and a differential signal receiving method thereof are provided to minimize the degradation of data restoration capability due to a skew by offering a display device which compensates the amount of an inner skew which is generated in each data channel of a low voltage differential signal reception terminal.;CONSTITUTION: A skew compensation type data receiving part(100) compares an input clock which is inputted by a program signal with a compensation clock after delaying the input clock. The skew compensation type data receiving part set an inner delay amount according to the comparison result. The skew compensation type data receiving part outputs a low voltage differential signal according to the preset delay amount after delaying the signal. A clock receiving part(200) delays the input clock as much as the fixed delay amount and outputs the clock as the compensation clock. A clock generation part(400) generates a clock for restoring data by using a delay clock. A data restoring logic(300) is synchronized with the clock for restoring data and restores the low voltage differential signal which is delayed from the data input part.;COPYRIGHT KIPO 2010
