Detailed ways

With the popularization of high-speed 4th Generation mobile communication technology (4G) and the upcoming 5th Generation mobile communication technology (5G) network, smart devices such as smartphones have become a The primary source of devices for creation and product consumption, which also drives the quest for larger screens. When the size of smartphones increases to the constraints of palm and pocket size, manufacturers naturally begin to pursue screen-to-body ratio.

In recent years, electronic equipment, especially the mobile phone industry, has set off a wave of full screen, and the so-called full screen is a relatively broad definition of mobile phone design with ultra-high screen ratio in the mobile phone industry. The screen and the four frame positions of the mobile phone are all frameless designs, pursuing a screen ratio close to 100%. However, due to the limitation of current technology, the full-screen mobile phone claimed by the industry is temporarily only a mobile phone with a super high screen ratio, and there is currently no mobile phone that can achieve a front screen ratio of 100%.

In the related art, in order to increase the screen ratio of an electronic device such as a mobile phone, a front camera or a camera module is usually made into a lifting structure, and the mobile phone is made into a sliding screen structure.

In a possible design, FIG. 1 is a schematic diagram of a front-facing camera of a mobile phone in the related art having a lifting structure. As shown in Figure 1, using the idea of mobile components, the front camera of the mobile phone is made into a lifting type, that is, when the front camera function is not used, the front camera is hidden in the mobile phone, and the front camera function needs to be used. , the front camera will automatically rise to complete the front camera. Through this technology, it can be made into a full-screen mobile phone with a screen ratio of up to 91.24%.

Specifically, the realization principle of the lifting structure of the front camera or the camera module is to precisely control the lifting stroke of the mechanical parts of the front camera through the cooperation of a micro stepping motor, an independent driving IC and a precision control algorithm. Among them, the hardware device responsible for mechanical transmission consists of three parts: stepping motor, reduction box and transmission screw. Each lift of the front camera or camera module relies on the torsion of the stepper motor to generate force, and the torque is amplified by the precision reducer to drive the screw to rotate to provide enough transmission force to drive the front camera to complete the lifting and The action of landing recovery.

In another possible design, FIG. 2 is a schematic diagram of a camera module of a mobile phone in the related art having a lifting structure. As shown in Figure 2, in order to improve the screen ratio of the mobile phone, a dual-track periscope structure is adopted, that is, a fully hidden 3D camera, which combines the optical components of the 3D structure, the front camera, the earpiece, and the rear dual camera and many other components. All are hidden inside the double-track periscope structure. During use, when you pick up the phone, it will automatically rise, and it will be automatically recovered after the phone is unlocked.

However, the lifting design of the front camera or the camera module needs to combine the mechanical structure with electronic control, which is not only complicated in structure, but also requires a response time (for example, about 800ms) for the mechanical structure during the expansion and contraction process, which is easy to be damaged. The dustproof and waterproof capabilities are relatively weak, and the pop-up camera itself is bulky, and the required motor and other structures take up too much space on the body, which makes the existing terminal relatively bulky and reduces the user experience.

In another possible design, FIG. 3 is a schematic structural diagram of a mobile phone using a sliding cover full screen in the related art. As shown in Figure 3, in this solution, the front camera/earpiece/sensor sensor, etc. are placed under the display screen. When a photo or Face ID detection is required, the user manually slides down the display screen, and the device under the screen leaks out to achieve the corresponding Function. The maturity and stability of the sliding cover structure in this way has been verified and optimized to the extreme. At the same time, the performance of the under-screen device has not been reduced due to volume restrictions, but the full-screen sliding cover technology separates the overall structure of the mobile phone into the display part, the screen and the screen. The lower device part, the electrical signal connection flexible printed circuit (FPC), and the mechanical structure connection slide rail, there is a problem of the life of the electrical signal connection to the FPC, and the slide rail results in an increase in the thickness of the mobile phone, which requires the user to manually open/reset The slider structure reduces the convenience of the user interface UI, which reduces the user experience.

To sum up, in view of the above problems existing in the related art, an embodiment of the present application provides an electronic device, including a transparent cover plate, a display screen, an optical signal sensor, and an optical component, wherein the display screen includes: a transparent cover plate and a transparent cover plate. The attached first display area and the second display area having an angle with the plane where the first display area is located, and the end of the second display area away from the first display area is provided with a light signal sensor, and the optical assembly is fixed on the light Between the signal sensor and the transparent cover, in the present application, the first display area is used to display the first part of the first display image, and the second display area is used to display the second part of the first display image, and the optical assembly can The second part displayed on the second display area is subjected to projection processing, so that the projected second part and the first part form a first display image, which is presented through the transparent cover. The optical assembly enables the user to observe the display image displayed on the full screen, avoiding the problem of poor user experience caused by the complex structure and easy damage caused by the lifting and lowering of the camera or the camera assembly and the sliding operation of the slide cover in the related art.
