摘要： A timing controller, a display device using the timing controller, and a method for driving the timing controller are discussed. The timing controller includes a frequency change sensing unit, that measures a length of an (n−1)th frame period and a length of an nth frame period, where n is a natural number equal to or greater than 2, and outputs timing signals of a low logic level when a length difference between the (n−1)th frame period and the nth frame period is greater than a predetermined first threshold value, a scan timing control signal output unit for outputting a scan timing control signal based on the timing signals, and a data timing control signal output unit controlling a data driving circuit based on the timing signals.

摘要： In a first aspect, a valve assembly is provided that includes a valve assembly output adapted to output at least one of DI water and a chemical. A first valve of the valve assembly includes (1) a first input adapted to receive the chemical; (2) a first output adapted to circulate the chemical to a chemical return; and (3) a second output adapted to output the chemical to the valve assembly output. The valve assembly also includes a second valve positioned downstream from the first valve. The second valve includes (1) an input adapted to receive deionized (DI) water; and (2) an output adapted to output DI water to the valve assembly output. A check valve is coupled between the second output of the first valve and the output of the second valve, and the first valve, second valve and check valve are included in a single manifold.
