Problems solved by technology

The white light source S has higher brightness in the wavelength distribution region of blue light and the wavelength distribution region of orange light. In contrast, the light intensity of the white light source S in the wavelength distribution region of green light will be obviously insufficient, thereby affecting organic Color Saturation of Light Emitting Display Device 200 and Brightness of Green Light During Display

Abstract

The invention relates to an organic electric-activated lighting display. Wherein, there are several pixel bits on the base plate; each pixel has the first electrode, organic lighting unit and the second electrode above the base plate; the first electrode has the first sub pixel area, the second sub pixel area, the third sub pixel area and the forth sub pixel area; the organic lighting unit comprises the first organic lighting unit and the second organic lighting unit, while the first one is above the first, second, third and the forth sub pixel areas, and the second one is above one of first, second, third and forth sub pixel areas, to improve the light transmission rate and color saturation.

Description

technical field [0001] The invention relates to a display device, in particular to a full-color organic electroluminescence display device, which can effectively improve the transmittance and color saturation of light sources of various colors, reduce power consumption and increase the production yield. Background technique [0002] Organic electroluminescent display devices (OLEDs) have become the mainstream of the next-generation flat-panel displays. Compared with liquid crystal displays, organic electroluminescent display devices have the advantages of wide viewing angle, high contrast and low power consumption, and may replace liquid crystal displays in the future and become another choice of flat-panel displays. However, how to achieve full-color display technology will be one of the important issues in the development of organic electroluminescent display devices, and may become a key factor affecting the success of organic electroluminescent display devices in the mar...
