| Abstract(in English) | A low temperature poly-Si TFT, when compared to a crystallized Si transistor, has the following difficulties : Low mobility and high threshold voltage. An integrated data-driver composed low temperature poly-Si TFTs consumes a great deal of power and can not operate with high frequency if it is formed using conventional circuits. We have developed an integrated data-driver, composed of low temperature poly-Si TFTs that produce a data sampling frequency twice as high as clock one. The shift registers, a part of the integrated data-driver, are divided into many blocks and each one is driven by an intermittent clock. We investigated the relation between power consumption and the number of the blocks to optimize the operating conditions. As a result, the sampling frequency of the data-driver was 1.7 times greater than conventional one and the power consumption of the circuit, which generates sampling signals, decreased to using only 16% of the conventional model. |
