Patent number: 8599122Abstract: A display device includes a gate driving part, a data driving part, a display panel and a kickback voltage compensating part. The gate driving part outputs a gate signal, and the data driving part outputs a data signal. The display panel displays an image in response to the gate signal and the data signal. A pixel voltage of the display panel is reduced by a kickback voltage varied based on a gray scale and induced when the gate signal falls. The kickback voltage compensating part compensates an image control signal externally provided to the kickback voltage compensating part for the kickback voltage to output a data control signal to the data driving part.Type: GrantFiled: February 13, 2008Date of Patent: December 3, 2013Assignee: Samsung Display Co., Ltd.Inventors: Kyoung-Ju Shin, Jun-Hyung Souk, Chong-Chul Chai

Patent number: 8026891Abstract: The present invention relates to a digital data transceiver circuit applicable to a flat panel display such as an LCD to be placed between graphic signal generation module and liquid crystal display module or between timing control IC and data driver IC, etc. A digital data transceiver circuit of the present invention has a first current source and a second current source, and the second current source is controlled to supply a current or not depending on the status of the lower bit of input data. A transmitter is connected to a node, on which the first and second current sources combine, and the transmission paths of currents from the two current sources are determined depending on the status of the upper bit of input data. A signal of the transmitter is transmitted through a transmission line, and a termination resistor is connected to the transmission line. A receiver detects output data according to a voltage applied to the termination resistor.Type: GrantFiled: June 9, 2006Date of Patent: September 27, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Jong-Seon Kim, Jun-Hyung Souk, Myung-Ryul Choi, Seung-Woo Lee

Patent number: 7923176Abstract: A mask includes a transparent substrate, a light-blocking layer and a halftone layer. The light-blocking layer includes a source electrode pattern portion including a first electrode portion, a second electrode portion and a third electrode portion, and a drain electrode pattern portion disposed between the second electrode portion and the third electrode portion. The halftone layer includes a halftone portion corresponding to a spaced-apart portion between the source electrode pattern portion and the drain electrode pattern portion, and a dummy halftone portion more protrusive than ends of the second electrode portion and the third electrode portion. Thus, a photoresist pattern corresponding to a channel portion of a thin film transistor (TFT) may be formed with a uniform thickness, to thereby prevent an excessive etching of the channel portion.Type: GrantFiled: February 21, 2008Date of Patent: April 12, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Chong-Chul Chai, Mee-Hye Jung, Woo-Geun Lee, Woo-Seok Jeon, Young-Wook Lee, Jung-In Park, Jun-Hyung Souk, Won-Kie Chang, Shi-Yul Kim
