Embodiment Construction

[0023] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] In order to solve the technical problems of low resolution of the organic electroluminescent display panel and low mask alignment accuracy in the sub-pixel unit preparation process, the present invention provides an organic electroluminescent display panel, by setting each sub-pixel unit to include multiple emitting The sub-pixel elements of the same light color can improve the alignment accuracy of MASK in the sub-pixel unit manufacturing process. In addition, two adjacent sub-pixel units emit different light colors, and multiple sub-pixel elements emitting different light colors form a pixel area of ​​the display panel to realize full-color display. At the same time, since the a...

Abstract

The invention relates to the technical field of organic electroluminescence display, and discloses an organic electroluminescence display panel. The organic electroluminescence display panel comprises a plurality of R sub pixel units, a plurality of G sub pixel units, a plurality of B sub pixel units and a plurality of W sub pixel units. Each R sub pixel unit comprises four R sub pixel elements, each G sub pixel unit comprises four G sub pixel elements, each B sub pixel unit comprises four B sub pixel elements, and each W sub pixel unit comprises four W sub pixel elements. Different colors are emitted by every two adjacent sub pixel units. The R sub pixel elements, the G sub pixel elements, the B sub pixel elements and the W sub pixel elements form a pixel area of the display panel, each sub pixel unit comprises four sub pixel elements which emit the same light colors, and the alignment precision of MASK in the preparation process can be improved. Meanwhile, due to the fact that the area of each sub pixel element is 1 / 4 of the area of each sub pixel unit, the resolution ratio of the organic electroluminescence display panel can be greatly improved to 4 times of the original resolution ratio.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence display, in particular to an organic electroluminescence display panel. Background technique [0002] Organic electroluminescent display panel is an emerging flat panel display device, which has self-illumination, low cost, fast response speed, wide viewing angle, low power consumption, high brightness, wide range of operating temperature, easy to realize flexible display and simple preparation process etc., has broad application prospects. [0003] The traditional organic electroluminescent element has a multi-layer structure, mainly an organic electroluminescent material layer is placed between the anode layer and the cathode layer to generate electroluminescence. Organic electroluminescent elements can be divided into two types according to the use of materials, one is small molecule light-emitting diodes based on dyes or pigments, called OLED (Organic Light-Emitting Diode)...
