[0041] The embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0042] Various modifications and changes can be made to the present application without departing from the spirit and scope of the present application. It is obvious that the present application is intended to cover modifications and changes as long as they fall within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the embodiments of the present application can be combined with each other without contradiction.

[0043] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0044] As described in the background section, when the OLED display screen is matched with the externally-hung touch screen, various touch-related film layers existing in the touch screen make the electronic device formed by matching the OLED display screen with the externally-hung touch screen have display bright spots when displaying a picture, which affects the display quality.

[0045] Specifically, after the electronic device formed by matching the OLED display screen with the externally-hung touch screen is lighted, the bright spots can be easily observed by the human eye when the display screen is watched, so that the display bright spots are easily observed by the human eye when the electronic device displays a pure color picture, thereby affecting the display quality of the electronic device. For example,Figure 1 and Figure 2 as shown, Figure 1 A schematic diagram of display bright spots when the electronic device is lit and displays a green solid color picture, wherein white represents display bright spots of the electronic device after being lit; Figure 2 A region A is a local enlarged view of a position where a display bright spot inside a touch screen of the electronic device is located.

[0046] The applicant has found that, in order to avoid problems such as display mottling, touch electrode pattern visualization, and moire patterns when the touch screen is stacked on the display side of the display screen, the transparent electrode is used to replace the metal electrode in the touch electrode in the touch screen.
