电致发光显示器件及电子装置
摘要：
能够产生清晰的多灰度彩色显示的EL显示器件及具有此EL显示器的电子装置。输入到EL元件110中的电流由设置在形成于象素104内的电流控制TFT108和EL元件110之间的电阻109进行控制,电阻109的电阻值高于电流控制TFT108的通态电阻值。由按时间控制EL元件110发光及不发光的时分驱动系统来进行灰度显示,以避免由电流控制TFT108特性偏移而导致的后果。
摘要（英）：

An EL display device capable of producing a vivid multi-gradation color display, and an electronic device having the EL display device. An electric current supplied to an EL element 110 is controlled by providing a resistor 109 between a current control TFT 108 and the EL element 110 formed in a pixel 104, the resistor 109 having a resistance higher than the on-resistance of the current control TFT 108. The gradation display is executed by a time-division drive system which controls the emission and non-emission of light of the EL element 110 by time, preventing the effect caused by a dispersion in the characteristics of the current control TFT 108.
