A color display device comprises an array of a plurality of sub-pixels including a red sub-pixel, a blue sub-pixel, a first green sub-pixel and a second green sub-pixel. The first green sub-pixel and the second green sub-pixel are smaller than that of the red sub-pixel or the blue sub-pixel. The two adjacent first green sub-pixels are arranged in a first direction, the two adjacent second green sub-pixels are arranged in the first direction. The blue sub-pixel is directly adjacent to the red sub-pixel in a second direction; the blue sub-pixel is directly adjacent to the two first green sub-pixels and the two second green sub-pixels.

Color display device

A liquid crystal display includes a first substrate and a second substrate opposed to each other with liquid crystal therebetween. A first pixel including a first TFT element and a first pixel electrode formed of a transparent conducting layer and disposed over the first substrate. A second pixel, adjacent to the first pixel, including a second TFT element and a second pixel electrode formed of a transparent conducting layer and disposed over the first substrate. A gate signal line disposed over the first substrate, is connected to the first and the second TFT elements. A drain signal line disposed over the first substrate and between the first and the second pixel electrodes, is connected to the second TFT element. A counter electrode formed of a transparent conducting layer and disposed over the first substrate, and is overlapped with the first and the second pixel electrodes and the drain signal line.

Liquid crystal display device

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.

Color display, liquid crystal display, and semi-transmissive liquid crystal display

A liquid crystal display includes a first substrate and a second substrate opposed to each other with a liquid crystal layer between the first substrate and the second substrate. The first substrate has a plurality of drain signal lines and a plurality of gate signal lines, and a plurality of pixel regions are defined by the drain signal lines and the gate signal lines. Each of the pixel regions includes a first electrode having a plurality of strip-like portions extending in an extension direction of the drain signal lines, the strip-like portions having at least one bent portion so that extension directions of each two parts of the strip-like portions separated by the at least one bent portion are different from each other, and a second electrode formed between the first substrate and the first electrode, and being overlapped with the strip-like portions in plan view.

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.

Secondary battery system

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.
