Abstract

The invention provides an organic light emitting diode (OLED) color display screen, which comprises a first substrate and a second substrate. The display screen is formed by arranging a plurality of pixels; each pixel comprises a red light sub-pixel, a green light sub-pixel, a blue light sub-pixel, and a driving circuit for driving the red light sub-pixel, the green light sub-pixel and the blue light sub-pixel to work; the red light sub-pixels, the green light sub-pixels and the blue light sub-pixels are respectively positioned on different planes of the two substrates or the same substrate; and the light emitting areas of the red light sub-pixel, the green light sub-pixel and the blue light sub-pixel of the same pixel are at least partially superposed in the direction vertical to the planes of the red light sub-pixel, the green light sub-pixel and the blue light sub-pixel. Meanwhile, the invention provides a manufacturing method for the OLED color display screen. The output quantity of blue light is improved by enlarging the area of the blue light pixels, so that the service life of the display screen is prolonged without affecting the resolution of the display screen.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to an OLED color display screen and a manufacturing method thereof. Background technique [0002] The pixel arrangement method widely used in displays is that three sub-pixels of red light, green light and blue light are arranged side by side on a plane of the substrate, such as figure 1 shown. In an OLED color display, the above-mentioned three sub-pixels of red light, green light, and blue light are formed by organic material coatings. Due to the short life of the blue light material and the shortest wavelength of the blue light, its photon energy is high and the luminous efficiency is low. This causes the output light intensity of blue light to be the smallest among the three sub-pixels of red light, green light and blue light in the same area; There is a big gap between the efficiency and lifespan of the three sub-pixels of green and blue, which will lead to the phenom...
