    摘要： In a conventional display device using light emitting elements, white color cannot be accurately displayed since the luminance of each sub-pixel varies for each color. Therefore, in order to achieve the uniformity in luminance of each sub-pixel, the amount of current or the current density flowing in light emitting elements is required to be changed for each color. In that case, a power source is necessarily provided for each color, thus an external circuit is increased, leading to increase in the cost and power consumption. According to the invention, a variable channel-size MOS transistor is used as a transistor for driving a light emitting element. When a signal voltage applied to a control gate is controlled for each sub-pixel, the amount of current or the current density flowing in light emitting elements can be adjusted and luminance of each sub-pixel can also be adjusted for each color.

    摘要翻译： 在使用发光元件的常规显示装置中，由于每个子像素的亮度对于每种颜色而变化，因此不能准确地显示白色。 因此，为了实现每个子像素的亮度的均匀性，需要为每种颜色改变在发光元件中流动的电流量或电流密度。 在这种情况下，必须为每种颜色提供电源，从而增加外部电路，导致成本和功耗的增加。 根据本发明，可变通道尺寸MOS晶体管用作驱动发光元件的晶体管。 当对每个子像素控制施加到控制栅极的信号电压时，可以调节在发光元件中流动的电流量或电流密度，并且还可以针对每种颜色调整每个子像素的亮度。
