  • Patent number: 11837128
    Abstract: A method for compressing and applying data of the sensing-less compensating system may be provided for a display device having subpixels. As the system can update an accumulated stress data of a subpixel which is accumulated according to a display driving data signal in a real time and perform a compensation, a real time compensation for a degradation of the subpixel can be performed without sensing the subpixel. Furthermore, as the system may provide a bit size information for restoration according to a comparison result of data subject to loss-compress and a loss reference value when loss-compressing the accumulated stress data, a loss ratio of a loss-compression data can be reduced. A display device and a sensing-less compensation system are also disclosed.
