and the transparent cover plate 204 covers on the back shell 201 to seal the groove structure and to form a closed space area for containing and protecting the circuit board 202 and the screen module 203 , and the light emitted by the screen module 203 penetrates through the transparent cover plate 204 to form a first display area 21 on the front surface of the phone body 2 , the first display area 21 can be used for the touch screen or the main screen in multi - screens of the phone body 2 . preferably , a ratio of area of the above - mentioned first display area 21 to the surface ( the surface used to cover ) of the cover area of the transparent cover plate 204 r is no less than 0 . 9 , such as the r is 0 . 9 , 0 . 92 , 0 . 95 or 0 . 98 , and even may be equal to 1 . preferably , the above - mentioned screen module 203 may be a liquid crystal display module or an amoled display module , such as a flexible amoled display module , etc . ; accordingly , the sides of the phone body 2 , such as the top side 211 and / or the bottom side 212 and / or the vertical side 213 , can be provided with flexible sides , to form the side display area . further , the above - mentioned phone body 2 also comprises a handset ( not marked in figure ) configured in the side , namely the handset can be configured in the groove structure and aligned to any one side edge ( such as the top side , the bottom side and the vertical side location , etc .) of the back shell 201 ; in addition , the above - mentioned handset is selectively exposed to the front side the first display area 21 , the top side or the vertical sides , and is configured near the position of the top side , for example , when the handset is configured on the vertical sides 213 , the handset is configured near the top side 211 , and is exposed to the front area of the first display area through an short angle or an opening configured on the transparent cover plate , so that the users can hear the sound played by the handset . preferably , the above - mentioned handset may comprise a handset module ( not shown ) and openings ( not shown ), and the handset module is configured in the back shell 201 ( such as in the above - mentioned groove structure ), the openings can be through - holes configured on the transparent cover plate 204 or through - holes formed by the gap on the transparent cover plate 204 together with the back shell 201 , to penetrate the transparent cover plate 204 , to transmit the sound played by the handset module to the outside of the phone body 2 , so that the users hear the sound . further , the above - mentioned phone body 2 further comprises a radio module ( not shown ), the radio module is configured to the position in relative to the above - mentioned receiver module , for example , the radio module is configured to the position in relative to the receiver module on the bottom side 212 of the phone body 2 , or the vertical sides 213 adjacent to the bottom side 212 , so as to collect the user &# 39 ; s voice . preferably , based on the openings in the above - mentioned handset , the back shell 201 and the transparent cover plate 204 are also provided with openings for transmitting voice in relative to the receiver module , the structure of the openings can be equal or approximate to the openings of the handset , and they may also be formed by any known way . further , the above - mentioned phone body 2 also comprises a camera module ( not shown ) which is configured on any other surfaces of the phone body 2 except the front side , namely the front side of the phone body 2 is not provided with a front camera . preferably , the camera module can be configured on the back side of the phone body 2 , and a second display area ( not shown in figure ) is formed on the back side , namely the phone body 2 is a multi - screen smartphone ; and the second display area can be displayed by one or more of the amoled screen , lcd display , electronic paper display , etc ., namely a single display or multiple displays can be configured on the second display area , and can be configured according to the requirement . preferably , the above - mentioned second display area can be used as self - timer for users , the resolution of the second display area is no greater than that of the first display area . in summary , in the above - mentioned embodiment of the invention , the necessary structures such as the handset are configured on the side or the back side of the mobile phone ( aligning to the edges of the mobile phone ), and the unnecessary structures such as physical buttons ( e . g ., home key , volume key , etc . ), front - facing camera are removed , so that the entire front surface of the mobile phone can be used to form the display area to realize the full - screen display without borders , and to enhance the beauty of the appearance of the smartphone , thus to effectively improve the user experience . the foregoing is only the preferred embodiments of the invention , not thus limiting embodiments and scope of the invention , those skilled in the art should be able to realize that the schemes obtained from the content of specification and figures of the invention are within the scope of the invention .
