APPARATUS AND METHOD FOR DISPLAYING GRAY LEVEL FONTS AND COMPUTER READABLE MEDIUM WHICH RECORDS PROGRAM FOR THE DISPLAYING GRAY LEVEL FONTS

摘要

PURPOSE: A device and method for displaying gray level fonts on a screen and a recording medium capable of being read by a computer including a program thereof are provided to display fonts data of 2-gray level as 2¬n('n' is a natural number which is bigger than '1') gray level for reducing a memory capacity which stores fonts. CONSTITUTION: 2-gray level font data are received from a 2-gray level font memory(501). The 2-gray level fonts data are copied and equally divided into the 'n' number of elements in accordance with a set 2¬n gray level(503). Each bit of the divided each 2-gray level font data is expanded to 'n' bits. At this time, each bit is expanded to '0' bit, one bit is expanded to '1' bit and the remaining bits are expanded to '0' bit with respect to '1' bit, and values of 2-gray level fonts data being expanded to 'n' bits are different(505). Data are selected and calculated out of each 'n' bits expanded 2-gray level fonts data and '0' data, and a calculation result value which expresses one gray level out of the 2¬n gray level is supplied as an LCD driver(507).
