    摘要： To provide a display device whose display can be recognized even in dark places or under the strong outside light. The display device performs display by controlling the number of gray scales in accordance with the intensity of outside light, which means a display mode can be switched in accordance with the data to be displayed on the display screen. A video signal generation circuit is controlled in each display mode in such a manner that it directly outputs an input video signal with an analog value, outputs a signal with a binary digital value, or outputs a signal with a multivalued digital value. As a result, gray scales displayed in pixels are timely changed. Accordingly, clear images can be displayed while maintaining high visibility in various environments, in the wide range from, for example, dark places or indoors (e.g., under a fluorescent lighting) to outdoors (e.g., under the sunlight).

    摘要翻译： 为了提供一种显示装置，即使在黑暗的地方或在强烈的外部光线下也能够识别显示。 显示装置通过根据外部光的强度控制灰度级数来进行显示，这意味着可以根据要在显示屏幕上显示的数据来切换显示模式。 视频信号发生电路以每个显示模式被控制，使得它直接输出具有模拟值的输入视频信号，输出具有二进制数字值的信号，或输出具有多值数字值的信号。 结果，以像素显示的灰度级是及时改变的。 因此，可以在例如暗处或室内（例如，在荧光照明下）到户外（例如，在阳光下）的广泛范围内，在各种环境中保持高可见度的同时显示清晰的图像。

    摘要： When a thin film transistor has an LDD structure or a double gate structure, the number of manufacturing steps increases, which may decrease the yield. The invention provides a display device where the influence of off current is reduced by a method different from the conventional one. According to the invention, a pass element is provided at one electrode of a light emitting element so as not to flow the off current of a transistor for driving the light emitting element through the light emitting element in a non-lighting period. The pass element allows the off current to flow outside, that is, the off current can be bypassed outside through the pass element.

    摘要： Degradations in light emitting elements occur with the passage of time. The invention provides a method of driving a light-emitting device provided with a plurality of pixels, which includes a light-emitting means with a first and a second electrodes, a drive means for supplying the light-emitting means with a current in response to an analog video signal, and a setting means for setting a sustaining period and an off time period within a frame period. The method of driving a light-emitting device is characterized by including the steps of: supplying the light-emitting means with the current in response to the analog video signal during the sustaining period; and turning the drive means off thereby to make the light-emitting means nonluminous or making the first and the second electrodes identical in potential thereby to make the light-emitting means nonluminous during the off time period.

    摘要： A display device with high-definition, in which display unevenness due to a voltage drop in a wiring or display unevenness due to a variation in characteristics of TFTs are suppressed. The display device of the invention comprises a first wiring for transmitting a video signal and a second wiring for supplying a current to a light emitting element. The first wiring and the second wiring extend parallel to each other, and are formed so as to overlap with each other at least partly with an insulating layer interposed therebetween.
