Abstract
Disclosed is a driving controller of an electronic device including a memory that stores the input image signal and outputs a previous image signal, a counter circuit that counts up a count value when the previous image signal corresponds to a black grayscale, and outputs a count value, a gain calculator that outputs a gain in response to the count value, and a compensation unit that outputs an image data signal based on the input image signal and the gain when the previous image signal corresponds to the black grayscale.
Claims20
A driving controller comprising:
- a memory configured to store an input image signal and to output a previous image signal;
- a counter circuit configured to count up a count value when the previous image signal corresponds to a black grayscale and to output the count value;
- a gain calculator configured to output a gain in response to the count value;
- and
- a compensation unit configured to output an image data signal based on the input image signal and the gain when the previous image signal corresponds to the black grayscale.
