Abstract:
1. An electron emission display device comprising: a display region comprising a plurality of scanning lines and a plurality of data lines; a plurality of pixels arranged in regions defined by the scanning lines and the data lines; a data driving unit for transmitting a data signal to the data lines; a scanning driving unit for transmitting a scanning signal to the scanning lines; and a controlling unit for identifying display data for indicating a brightness displayed by the pixels, for separately determining a compensation coefficient for each of the pixels, and for correcting input data input into each of the pixels; wherein the input data for each of the pixels is corrected in the controlling unit by multiplying the compensation coefficient by the input data, wherein the controlling unit comprises: wherein the compensation coefficient of each of the pixels is in the form of a first constant value divided by a second constant value, the second constant value being greater than one or less than one.
