  • Patent number: 10854156
    Abstract: A display device includes a plurality of pixels arranged in a matrix. Overlapping areas between gate electrodes and drain electrodes of switching elements connected to a plurality of selected pixel electrodes are individually set to equalize or substantially equalize retention voltages Vd(+) (Vd(?)) of the selected pixel electrodes when a specific voltage of a first polarity is applied to the selected pixel electrodes. The source application section is controlled to apply to the source lines source signals Vsc each of which is corrected by superposing a correction voltage preset for each source line on the source signal Vs(?) (Vs(+)) in application of a voltage of a second polarity to the selected pixel electrodes.

  • Publication number: 20200356471
    Abstract: A storage system monitors the first access frequency of occurrence which is the access frequency of occurrence from a host device during a first period, and the second access frequency of occurrence which is the access frequency of occurrence from a host device during a second period shorter than the first period. Along with performing data relocation among the tiers (levels) in the first period cycle based on the first access frequency of occurrence, the storage system performs a decision whether or not to perform a second relocation based on the first access frequency of occurrence and the second access frequency of occurrence, synchronously with access from a host device. Here the threshold value utilized in a decision on whether or not to perform the first relocation is different from the threshold value utilized in a decision on whether or not to perform the second relocation.
