Abstract
A controller and a display device including the controller are discussed. The display device can perform a compensation based on a stress value for each sub-pixel and update a correction table used for compensation using a sensing value acquired at a preset period. As such, it is possible to improve the accuracy of real-time compensation. In addition, since it is possible to compensate for a sub-pixel for which a sensing value is not acquired using an indirect gain according to the ratio of the stress values of the sub-pixel to a sensing value, the accuracy of compensation can be improved even if sensing for each sub-pixel sharing a sensing line may not be easy.
