Organic light-emitting diode display device

Abstract

The invention discloses an organic light-emitting diode display device which comprises a substrate, a color photoresist layer and a white-light organic light-emitting diode. The color photoresist layer is arranged on the substrate; the white-light organic light-emitting diode is arranged on the color photoresist layer and comprises a reflecting electrode, a through electrode and a white-light organic luminous layer which is arranged between the reflecting electrode and the through electrode for generating white light, wherein the color photoresist layer at least comprises first to third photoresist regions which respectively comprise red, green and blue pigment particles and red, green and blue light contents respectively filtered from the white light; and the color photoresist layer at least acquires a needed haze value, such as a value large than 30 by the scattering effect of the red, green and blue pigment particles and / or the doped scattering particles different from the red, green and blue pigment particles in the first to third photoresist regions. The organic light-emitting diode display device has higher light-emitting efficiency.

Description

technical field [0001] The invention relates to the field of display technology, and in particular to an organic light emitting diode display device. Background technique [0002] Press, Organic Light Emitting Diode (OLED) will become one of the next-generation new display methods due to its advantages of lightness, thinness, high chroma, high contrast, and being able to be made on a flexible substrate. At present, full-color OLED displays can be mainly divided into three-color separation of red, green and blue OLEDs or a structure of white OLEDs combined with color filters. Among them, as far as the three-color separation structure of red, green and blue organic light-emitting diodes is concerned, it is necessary to use a shadow mask to define the positions of red, green and blue polarized light-emitting diodes, so there will be low resolution and very low resolution. Difficult to scale up. As for the structure of white organic light-emitting diodes with color filters, be...

Problems solved by technology

Among them, as far as the three-color separation structure of red, green and blue organic light-emitting diodes is concerned, it is necessary to use a shadow mask to define the positions of red, green and blue polarized light-emitting diodes, so there will be low resolution and very large Difficult to scale up

As for the structure of white organic light-emitting diodes with color filters, because the mature yellow light technology is used to define red, green and blue sub-pixels, there is no problem in terms of resolution and enlargement, but the disadvantage is the light output efficiency. lower

Therefore, if organic light-emitting diodes are to be used as large-scale displays such as televisions (TVs), white organic light-emitting diodes combined with color filters is a more feasible technology, but the problem of low light extraction efficiency needs to be improved.
