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 us

Example Embodiment

[0028] See figure 1 , Which depicts a schematic structural diagram of an organic light emitting diode display device related to the first embodiment of the present invention.

[0029] Such as figure 1 As shown, the organic light emitting diode display device 10 in this embodiment includes a substrate 12, a color photoresist layer 14 and a white light organic light emitting diode 16. Wherein, the substrate 12 is usually made of a transparent material, such as glass. The color photoresist layer 14 is disposed on the substrate 12 and includes photoresist regions 141, 143 and 145. The photoresist area 141 includes pigment particles 142, such as red (R) pigment particles and mixed with scattering particles 148, and the photoresist area 143 includes pigment particles 144, such as green (G) pigment particles and mixed with scattering particles 148, The photoresist area 145 contains pigment particles 146, such as blue (B) pigment particles and mixed with scattering particles 148; the pa...

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...
