Problems solved by technology
However, the light transmittance of CF is low, which will lead to attenuation of brightness and loss of luminous efficiency, and the color gamut is limited by the color gamut of CF.
To increase the color gamut, the thickness of CF must be increased, which leads to a further reduction in light transmittance and reduces the brightness of the device

Abstract
The invention relates to a silicon-based OLED (Organic Light Emitting Diode) micro-display which sequentially comprises a silicon-based substrate, a metal anode layer, an organic functional layer, a transparent conductive film layer, a semi-transparent and semi-reflective metal layer, a thin film packaging layer, a color photoresist layer and a glass cover plate from bottom to top, the metal anode layer comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel; the thicknesses of the parts, corresponding to the red sub-pixels, the green sub-pixels and the blue sub-pixels, of the transparent conductive film layer are different; and the metal anode layer, the organic functional layer, the transparent conductive film layer and the semi-transparent and semi-reflective metal layer form an F-P type microcavity. According to the invention, the brightness and the color gamut of the OLED micro-display can be effectively improved.
Description
technical field [0001] The invention relates to the field of microdisplays, in particular to a silicon-based OLED microdisplay. Background technique [0002] At present, the OLED panel industry usually adopts the following two methods to realize full-color display: 1. Use red, green and blue sub-pixels in parallel; 2. Use white OLED plus color filter film (CF). Method 1 has been widely used in the field of small and medium-sized AMOLEDs. Its advantage is that it does not require a color filter film and will not cause loss of brightness, so it can achieve high brightness and low power consumption. [0003] However, in the field of micro-display, the sub-pixel size is usually less than 5 μm. Currently, it is limited by the alignment accuracy of OLED evaporation equipment, and the opening of the fine metal mask (FMM) cannot be made small enough to match the panel. of sub-pixels. Therefore, in the field, a white light OLED plus a color filter film is usually used to realize fu...
