Abstract:
A liquid crystal display system which converts first display data having a first resolution into second display data having a second resolution different from the first resolution, the liquid crystal display system comprising:a liquid crystal display panel including a plurality of dots disposed in a matrix; anda data conversion section whichreceives the first display data from an external system,divides a set of M contiguous dots on a horizontal line of the first display data into N partitions, where M and N are integers, M.gtoreq.3, 2.ltoreq.N<M, and N/M is a reduction ratio,generates a set of N contiguous dots on a horizontal line of the second display data respectively corresponding to the N partitions based on the set of M contiguous dots on the horizontal line of the first display data by performing, for each one of the N partitions, a weighted addition of data values of ones of the M contiguous dots contained in the one of the N partitions to obtain a data value of a corresponding one of the N contiguous dots, wherein when one dot of the M contiguous dots is located on a border between two partitions of the N partitions, the data value of the one dot is assigned to each of the two partitions with a respective weight for each of the two partitions representing a respective percentage of an area of the one dot contained in a respective one of the two partitions, andoutputs the second display data to be displayed on the liquid crystal display panel.
