Description
Technical field
The present invention relates to technical field of flat panel display, particularly a kind of displayer part.
Background technology
Organic light emitting display utilizes Organic Light Emitting Diode (English full name Organic Lighting EmittingDiode is called for short OLED) to show image, is a kind of display device of active illuminating.According to the difference of type of drive, organic light emitting display is divided into passive-matrix organic light emitting display (English full name PassiveMatrix Organic Lighting Emitting Display, be called for short PMOLED) and active matrix organic light-emitting display part (English full name Active Matrix Organic Lighting Emitting Display, be called for short AMOLED), active matrix organic light-emitting display part is also referred to as active matrix organic light-emitting display device.Wherein, displayer part is because of its high chroma territory, high response speed, the feature such as more frivolous, just replacing Thin Film Transistor-LCD (English full name Thin Film Transistor liquid crystaldisplay is called for short TFT-LCD) at present and becoming the strong competitor of technical field of flat panel display of future generation gradually.
At present, the colour technology of AMOLED is divided into WOLED technology and RGB-OLED technology.Wherein, the mode that WOLED technology adopts white light to be filtered by color film (English full name Color Filter is called for short CF) realizes colorize, because current CF can support higher resolution, therefore, the resolution of WOLED mode can be suitable with the resolution capabilities of liquid crystal.But WOLED technology needs three kinds of OLED to be together in series and sends white light and then filter, and therefore, can produce higher power consumption, be not suitable for mobile display field.And RGB-OLED technology needs to adopt fine metal mask (FMM) technique, by the figure of RGB, evaporation is on the sub-pixel of viewing area respectively, and each sub-pixel is a corresponding color evaporation figure (also claiming OLED figure) generally.
