Abstract
A liquid-crystal display panel includes: gate lines each serving as a row-direction line which is one of the rows of a two-dimensional matrix; data signal lines each serving as a column-direction line which is one of the columns of the two-dimensional matrix; a plurality of liquid-crystal pixel sections which are laid out to form the two-dimensional matrix and each placed at the intersection of one of the gate lines and one of the data signal lines; chopper-type comparators each connected to one of the data signal lines and each used for converting the value of a sensor signal read out from one of the liquid-crystal pixel sections connected to the data signal lines into a binary value; and a shift register for converting outputs of the chopper-type comparators from parallel data into serial data and outputting the serial data.
