TIMING CONTROL UNIT CAPABLE OF REDUCING THE NUMBER OF LAYERS OF A PRINTED CIRCUIT BOARD AND LOWERING THE MANUFACTURING COSTS AND A LIQUID CRYSTAL DISPLAY INCLUDING THE SAME

摘要

PURPOSE: A timing control unit and a liquid crystal display including the same are provided to reduce the number of layers of a printed circuit board and lower the manufacturing costs by including a level shifter in the timing control unit and thus removing separate pin assignment or wiring.;CONSTITUTION: A timing control unit (140) includes a control signal generating part (142) which generates multiple first gate control signals (CONT1) and data control signals (CONT2) using horizontal synchronization signals (Hsync), vertical synchronizing signals (Vsync), main clock signals (DCLK), data enable signals (DE), etc. from external systems; a level shifter (144) which outputs a first gate voltage (VGH), a second gate voltage (VGL), a driving voltage (VDD), and multiple second gate control signals (CONT1'); and a data processing part (146).;COPYRIGHT KIPO 2013;[Reference numerals] (142) Control signal generating part; (144) Level shifter; (146) Data processing part
