Abstract

The invention discloses an OLED display panel, a preparation method thereof and an OLED display device. A display area of the OLED display panel comprises at least one function additional area and a normal display area arranged around the function additional area. In the function additional area, the anode layer is divided into a plurality of light-transmitting areas, a plurality of pixel electrode areas and lightproof regions arranged around the light-transmitting regions and the pixel electrode areas. Patterned anode metal is arranged in the pixel electrode area, and anode metal is not arranged in the light-transmitting area. Differential design is performed on the anode metal pattern of the anode layer in the function additional area, so that the light transmittance of the function additional area is increased on the basis of ensuring the normal display function of the function additional area.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel based on CUP technology, a preparation method thereof, and an OLED display device. Background technique [0002] Since the advent of the full-screen concept of mobile phones, the industry chain has been working hard to achieve a full-screen display in the true sense. Nowadays, the "full panel" design has become the mainstream, and the full panel is a relatively broad definition in the display industry for the design of ultra-high screen-to-body ratio display devices. The literal explanation is that the front of the display device is all screens, the display area is completely covered by the screen, and the borderless design is adopted around the display area, pursuing an ultra-high screen-to-body ratio close to 100%. [0003] In order to meet the demand for full-screen mobile phones, panel developers put more energy into the development of organi...
