In recent years, the market development of mobile terminals stimulates the progress of novel display technologies, and in order to match the requirements of large-screen display and high-screen ratio of the mobile terminals, the mobile phone industry introduces a comprehensive screen concept in two years, aiming at improving the screen ratio of the mobile phone screen. In order to achieve an ideal full-screen display state, practitioners around the world have developed many under-screen camera solutions.
In the prior art, because the corresponding positions need to be reserved on one side of a mobile phone screen for assembling a mobile phone call module and a camera module, a circular notch part (notch) is arranged at the top end of the screen for placing the call and the camera module, such as iphone XS, hua is P30 pro and the like. There are also openings designed in the camera area, such as samsung S10 series, because the process is to cut off part of the display area by laser, the frame of the opening in the punching area needs to be wider to prevent the display area from being damaged by laser cutting. While the design yields panels that increase the screen fraction of the end product, the circular cut and perforated areas are still obtrusive to the appearance of the product and are far from the true overall screen concept.
To achieve a relatively realistic design for camera shooting under the screen, terminal designers have attempted to improve upon handset module designs such as Oppo Find X, Vivo Nex, etc., but such designs increase handset manufacturing complexity and risk of damage.
