摘要： An image display system includes a host side for executing an application and transmitting image data having a P dot width in a block unit with the number of m dots as the width of the block. A panel side is connected through a digital I/F line to the host side, which converts the image data having a P dot width by using magnification to produce data having an R dot width and then displays the image data. The panel side executes scaling by using a block having an integral value obtained by a R×m/P set as a dot width and a block having a dot width of an added integral value obtained by adding 1 to the integral value, and converts by magnification the image data received from the host side in block unit based on the executed scaling and displays the image data on a panel.

摘要： To generate a dot clock for a liquid crystal display device from a horizontal sync signal with reduced skew, a phase locked loop (PLL) is divided into three functional parts. The first part generates a particular frequency by supplying voltage from a latch type DAC (digital/analog converter) to a VCO (voltage controller oscillator). A horizontal sync signal is estimated from the dot clock signal that is finally generated and the output value of the DAC is increased or decreased in accordance with the difference between this estimated horizontal sync signal and the actual horizontal sync signal. This increase or decrease correction is made at, for example, the vertical sync timing. The second part achieves synchronization. A signal corresponding to the phase error between the actual horizontal sync signal and the dot clock signal is added to the signal from the DAC to control the phase of the dot clock. The third part is a PLL for generating the dot clock in accordance with the signal generated by the first part at the particular frequency.
