This claim stood out as interesting.
Also interesting to me was the unique visualization in certain of the figures, for example,The device of claim 2, wherein when the number of the plurality of rows of the first block is p and the number of the plurality of rows of the first block receiving the black level voltage is q, the data voltage is modified such that the luminance increases by p/(p−q) times.
I hadn't seen this type of visualization in previous patents. Better fidelity figures for this patent may be found in the corresponding Korean patent.
