DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

A display device and a driving method thereof are disclosed. In one aspect, the display device includes a display panel including a plurality of pixels, a data driver transferring data voltages to a plurality of data lines, and a gate driver transferring gate signals to a plurality of gate lines. The display device also includes a signal controller controlling the data driver and the gate driver and including a signal processor. The signal processor includes a memory and a coupling index calculator calculating a coupling index which represents a coupling degree between adjacent rows. The signal processor compensates for the input image signal to generate a compensated image signal based at least in part on the coupling index.

1. A display device, comprising:
a display panel including a plurality of pixels arranged in rows, a plurality of data lines, and a plurality of gate lines; a data driver configured to apply a plurality of data voltages to the data lines; a gate driver configured to apply a plurality of gate signals to the gate lines; and a signal controller including a signal processor, wherein the signal controller is configured to control the data driver and the gate driver, wherein the signal processor includes:
a memory storing: i) an input image signal of the (N−1)-th row and ii) an input image signal of the N-th row, wherein N is a natural number of 2 or more; anda coupling index calculator configured to calculate a coupling index which represents a degree of coupling between adjacent rows, andwherein the signal processor is configured to compensate for the input image signal of a pixel of the N-th row to generate a compensated image signal based at least in part on: i) an input image signal of the (N+1)-th row, ii) the input image signal of the (N−1)-th row, iii) the input image signal of the N-th row, and iv) the calculated coupling index.
