Problems solved by technology

However, the irregularly cut OLED display panel has obvious disadvantages, such as complex cutting process, which will obviously increase the production cost; the difficulty of thin film packaging in the shaped cutting area increases, and the packaging reliability decreases; GOA near the "U" groove area The line layout is different from other areas, which may cause uneven display brightness in this area; when playing pictures or videos in full screen, the "U" groove area will block part of the screen

Embodiment Construction

[0037] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings. It should be noted that the drawings in this application are only schematic diagrams. Unless otherwise specified, they do not mean that the actual thickness ratio, flatness, and shape of each film layer are the same as those in the drawings. Due to limitations, the actual product will have certain differences from the schematic diagram, such as the shape of the hole and the appearance of the joint part of each film layer will be different from the schematic diagram, which can be understood and known by those skilled in the art.

[0038] Please also see Figure 1 to Figure 3 , The present invention provides an OLED display panel, comprising at least one transparent display area B and an effective display area A surrounding the transparent display...

Abstract

The invention provides an OLED display panel and a mobile phone. The OLED display panel is provided with a transparent display area and an effective display area which surrounds the transparent display area and covers the OLED display panel. When the OLED display panel is applied to the mobile phone, the transparent display area is used for accordingly mounting an electronic device placed in advance below the transparent display area, high screen-to-body ratio can be realized, and better visual experience is brought to a user; the effective display area is additionally provided with one OLED anode layer and one OLED luminous layer compared with the transparent display area, so as to normally display a picture, except the OLED anode layer and the OLED luminous layer, the effective display area and the transparent display area are the same in arrangement of films, the same films can be produced in the same production process, special-shaped cutting can be avoided, a production technologyis simplified, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel. Background technique [0002] Organic light emitting diode display panel (Organic Light Emitting Diode, OLED) is a display product with great development prospects. The advantages of small size, low driving voltage, wide operating temperature range, simple production process, high luminous efficiency and flexible display have won the favor of major display panel manufacturers and have become the main force of the third-generation display devices in the field of display technology. [0003] In recent years, with the development of portable electronic display devices, the pursuit of high screen-to-body ratio and extreme ultra-narrow bezel, known as "full screen" display panel has become a research and development hotspot in the field of small and medium-sized display panels, and has already been used in mobile phones. applied on the display. [0004] The a...
