Patent Searching and Data


Title:
CURRENT SAMPLE/HOLD CIRCUIT, CURRENT SAMPLE/HOLD METHOD, REVERSE DEMULTIPLEXING DEVICE USING SAME, AND DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3850425
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a sample/hold circuit having different current source/sink configuration in each input end and output end.
SOLUTION: The sample/hold circuit includes a first transistor for sampling and holding a data current to be absorbed into an output end of a data driver, a capacitor, and a plurality of switches. When the data current which is sampled and held is provided to a data line, the data current is absorbed into the output end of the sample/hold circuit. The sample/hold circuit can be used with the data driver having the output end which has the current sink configuration.
