Manufacturing method of organic light emitting diode back plate and the organic light emitting diode back plate
Provided are a manufacturing method of an organic light emitting diode back plate and the organic light emitting diode back plate. In the manufacturing method of an OLED back plate, pixel openings and light blocking grooves correspondingly above active layers are formed in a pixel definition layer. Then, OLED light-emitting functional layers are formed in the pixel openings and the black light shielding blocks completely covering the active layers are formed in the light shielding grooves by ink jet printing, thereby effectively preventing the TFT elements from being affected by the illumination and ensuring the characteristics of the TFT elements. The structure is simple and the production cost is low.
