Abstract: A display apparatus that has a light and thin panel module to be capable of preventing noise. In the display apparatus, the row and source drivers for driving the display panel is controlled by the timing control board which is positioned on main printed circuit board of the notebook computer body. The timing control board is connected with the row and source drivers by the flexible printed circuit film.

Abstract: A data interface device is constructed to minimize electromagnetic interference in a liquid crystal display device. The data interface device has a data input arranged to input data which is synchronized with a desired frequency of a data clock. A clock modulator modulates the data clock to provide a modulated clock signal having a frequency within a certain range of frequency so as to minimize EMI when data is transmitted using the data clock. A variable data transmission speed controller responds to the data clock and the modulated clock in such a manner that a transmission speed of the data is varied in a manner to minimize EMI.

Abstract: A data transmitting apparatus and method minimizes the electromagnetic interference (EMI) when transmitting parallel data via transmission lines. A controller receives data inputs synchronized to an input clock signal. The controller frequency-divides the input clock signal by a desired number, and separates the data into a plurality of separated data in such a manner to that one group of separated data has a phase difference relative to another group of separated data and is synchronized to the frequency-divided clock signal. Drive circuits receive the separated groups of data and sample the data at a falling edge or a rising edge of the frequency-divided clock signal such that sampling of one group occurs at different times than sampling of another group.
