  • Patent number: 10551664
    Abstract: In a color display device, when using white (W) sub-pixels in addition to subpixels of red (R) and green (G) plus blue (B) without increasing a wiring line number, the per-color pixel number in a unit area decreases so that the image resolution is deteriorated. The area and number of subpixels are adjusted in accordance with the visual sensitivity or luminosity required. Practically, the area of red (R) and blue (B) subpixels which are relatively low in luminosity is set to be about two times greater than the area of green (G) and white (W) subpixels that are relatively high in luminosity while letting the number of green (G) and white (W) subpixels be twice the number of red (R) and blue (B) subpixels. A larger subpixel is configured from a plurality of unit subpixels. A smaller subpixel is formed of a one unit subpixel.

  • Patent number: 10338984
    Abstract: Detecting a defective cell in a memory in consideration of an error property difference depending on the storage state. A determination unit determines whether there is a possibility of defect for each of unit-of-storages on a memory cell formed with a non-volatile memory. The non-volatile memory undergoes either a reset operation that transitions a state from a low resistive state (LRS) to a high resistive state (HRS) or a set operation that transitions the state from the high resistive state to the low resistive state. The determination unit determines a unit-of-storage in which the number of errors in predetermined one of the reset operation and the set operation has exceeded a predetermined standard, as a unit-of-storage suspected of having a defect.

  • Patent number: 8994322
    Abstract: Since in existent charge-discharge control the battery direct current resistance of a lithium ion battery increases at a low temperature or in a low SOC, the battery voltage may possibly exceed greatly the maximum allowable voltage instantaneously due to over-voltage during charging or may possibly decrease greatly to less than the minimum allowable voltage during discharging. If the lithium ion battery continuously lies in such a state the battery performance is degraded abruptly. The battery resistance of a lithium ion battery module is estimated in accordance with SOC and temperature of the lithium ion battery module, and current to charge is set properly based on the estimated battery resistance.

  • Patent number: 8984943
    Abstract: The present invention provides an inspection method for a lithium ion secondary battery in which an electrolyte and an electrode group are disposed in one container, the electrode group including a positive electrode, a negative electrode, and a separator, wherein a sensor for detecting acoustic emission is attached to the outside of the container and acoustic emission generated in the battery container is detected upon provision of charge or discharge current and stopping of provision thereof between the positive electrode and the negative electrode. Specifically, the amplitude intensity of the acoustic emission is measured that is generated upon provision of charge-discharge currents having different values, linear approximation is conducted for the charge-discharge current value and the amplitude intensity of the acoustic emission, and the number of times of charge-discharge cycles that has been provided so far to the battery is estimated.

  • Publication number: 20150056478
    Abstract: Provided is a secondary battery system adapted to immediately detect that a lithium-ion secondary battery has entered a region in which the battery deteriorates in accordance with the t-law. The lithium-ion secondary battery system includes: a lithium-ion secondary battery; an acoustic emission (AE) sensor that detects an AE signal occurred in the lithium-ion secondary battery; an AE signal detector that detects the AE signal sent from the AE sensor; and a controller to which a signal from the AE signal detector is input. When a count of AE events which occur in a low-voltage region of one charge/discharge cycle of the lithium-ion secondary battery equals or exceeds a threshold value, the controller outputs a signal denoting a start of the deterioration of the lithium-ion secondary battery.
