Description

technical field [0001] The invention relates to the display field, in particular to an electroluminescent device and a preparation method thereof. Background technique [0002] Organic Light Emitting Diode (OLED), also known as Organic Electroluminescence Display (OELD), has self-illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response, and wide temperature range. Due to its excellent features such as simple structure and manufacturing process, it has been widely used in mobile communication terminals, personal digital assistants (PDAs), and handheld computers recently. OLED devices are divided into passive matrix and active matrix OLED devices. Active matrix OLED means that each OLED is controlled by a thin film transistor (ThinFilmTransistor, TFT) circuit to control the current flowing through the OLED, which has high luminous efficiency and The image shows good features. [0003] An existing active matrix OLED display device such as ...
