Embodiment Construction

[0017] The following examples will be used as a reference for the present invention in detail. FIG. 2 a shows a schematic cross-sectional view of a top emitting organic electroluminescent device 60 according to an embodiment. The organic electroluminescent device 60 includes: a pixel array substrate 200 , a color filter substrate 300 and an organic electroluminescent multilayer structure 250 . In this embodiment, the pixel array substrate 200 and the color filter substrate 300 can be glass, quartz, or other transparent substrates. The pixel array substrate 200 has a plurality of pixel areas, and each pixel area may include a first sub-pixel area 201, a second sub-pixel area 202, a third sub-pixel area 203, and a fourth sub-pixel area 204, respectively to display red, green, blue and white. Furthermore, one or more insulating layers may be formed on the pixel array substrate 200 to serve as a buffer layer, an interlayer dielectric (ILD) layer, an inter-pixel dielectric layer,...

Abstract

An electromechanical exciting light display device comprises an array base plate provided with a white light secondary pixel area and an electromechanical exciting light multilayered structure which is arranged on the white light secondary pixel area of the array base plate and comprises a lower electrode, wherein the lower electrode is provided with a thinner first part and a thicker second part, thereby different optical wavelength offset directions are provided.

Description

technical field [0001] The present invention relates to an organic electroluminescent device, in particular to an organic electroluminescent device (organic light-emitting device, OLED) with a micro-cavity structure. Background technique [0002] Organic Light Emitting Diode (OLED) devices are widely used in fields such as flat panel displays by utilizing the characteristic of emitting light when organic thin film materials are excited by electric current. OLED devices usually have a sandwich structure consisting of an anode, a cathode and an organic thin film sandwiched therebetween. Among the active matrix OLED elements, the OLED structure can be divided into two types, one is a bottom emitting (bottom emitting) OLED structure, and the other is a top emitting (top emitting) OLED structure. [0003] Please refer to FIG. 1 , which shows a cross-sectional view of a conventional top-emitting OLED structure. The conventional top-emitting OLED structure 100 includes a reflecti...
