Abstract:
1. A display device, comprising: a timing controller configured to: a touch sensing unit configured to detect the user's touch with a display to touch crosstalk (DTX) compensation value calculated by multiplying a DTX weight value and a maximum DTX amplitude of a touch sensing block, the maximum DTX amplitude being obtained when a maximum grayscale value is applied to a plurality of pixels corresponding to the touch sensing block, in the touch mode, the DTX weight value being calculated by substituting an average value of grayscale values applied to the plurality of pixels corresponding to the touch sensing block into a normalization curve, wherein the normalization curve is calculated by normalizing DTX amplitude change characteristics of the touch sensing block based on changes in the grayscale values applied to the plurality of pixels corresponding to the touch sensing block.
