摘要： The switching between the normal operation mode and the memory operation mode is achieved by disposing one retaining circuit 110 for a plurality of pixel elements (for example, 2 or 4 pixel elements). The retaining circuit 110, which is a SRAM, requires considerable circuit space. The sharing of one retaining circuit by a plurality of the pixel elements enables the reduction of the seeming “number of the pixel elements” under the memory operation mode. This can lead to the size reduction of the pixel element, achieving the finer display under the normal operation mode. Also, the reduction in the number of the retaining circuits can further reduce the energy consumption under the memory operation mode, comparing to the case where the retaining circuit 110 is disposed for each of the pixel elements.
摘要翻译：正常操作模式和存储器操作模式之间的切换通过为多个像素元件（例如，2或4个像素元件）设置一个保持电路110来实现。作为SRAM的保持电路110需要相当大的电路空间。通过多个像素元件共享一个保持电路使得能够在存储器操作模式下减少看起来的“数量的像素元件”。这可以导致像素元件的尺寸减小，在正常操作模式下实现更精细的显示。此外，与为每个像素元件设置保持电路110的情况相比，保持电路的数量的减少可以进一步降低存储器操作模式下的能量消耗。

摘要： In a display device using, for example, an organic EL element as a light emissive element, a single pixel is formed of subpixels of four colors, R, G, B, and W, arranged in two rows and two columns. Each pixel is substantially quadrangular in shape, and at least one of the subpixels in the pixel has an area different from the areas of the other subpixels. The subpixels of the colors horizontally adjoining in the same row have the same height, and the subpixels of the colors vertically adjoining in the same column have the same width. Even when the area ratio of the subpixels is varied by changing the position of the intersecting point of divisional lines dividing a pixel into four subpixels, the design can easily be modified by satisfying the above relationship, and a display device with a high luminance and a long life can easily be obtained with any area ratio.

摘要： A control circuit of a control part sets the gate potential of a p-channel MOSFET of a driver part to a level lowering from a supply potential by at least the threshold voltage of the p-channel MOSFET while setting the gate potential of an n-channel MOSFET to a level rising from a low level of an input signal by at least the threshold voltage of the n-channel MOSFET in response to the input signal, thereby strongly turning on one of the p-channel MOSFET and the n-channel MOSFET and weakly turning on the other MOSFET.

摘要： A switching transistor to connect a pair of bit lines in a sub array to a pair of common bit lines in a sense amplifier band is arranged between a P channel sense amplifier and an N channel sense amplifier. Accordingly, the switching transistor can be used of a threshold value identical to that of the NMOSFET used in a logic circuit region, not a low threshold value. Therefore, the switching transistor can be reliably turned on/off in a narrow operating range. Accordingly, the complexity or capability of the drive circuit can be suppressed to a low level. As a result, the area for the semiconductor memory device can be reduced.
