Problems solved by technology

Although the polarizing film can reduce the reflectance and improve the contrast ratio of the display device outdoors, its transmittance is very low, about 40%, so that the organic electroluminescent diode needs to be higher than the original no matter whether it is indoors or outdoors. brightness to drive, thus shortening the life of the original organic light-emitting diode and more power consumption

Abstract

The display device includes first and second base plates, at least an organic electro photoluminescence device, at least an optical color change film. First and second base plates are setup in parallel and opposite. At least one organic electro photoluminescence device is setup on a base plate and between first and second base plates. At least one optical color change film is setup at first and / or second base plate. Thus, light source from the organic electro photoluminescence device will pass through the optical color change film.

Description

technical field [0001] The present invention relates to a flat display device, in particular to an organic electroluminescence display device, which is used to maintain the contrast while improving the light transmittance (light utilization rate). Background technique [0002] An organic electroluminescent diode (OELD) is a self-luminous device using organic materials. Compared with traditional inorganic light-emitting diodes (LEDs), which require strict crystal growth requirements, organic electroluminescent diodes can be easily fabricated on large-area substrates to form amorphous thin films. On the other hand, OLED is also different from liquid crystal display technology and does not require a backlight module, so the process can be effectively simplified. With the rapid development of technology, organic electroluminescent diodes will be used in small-sized full-color display panels such as personal digital assistants and digital cameras in the future. Once this technol...
