In the terminal device, the first display module 10 and the second display module 20 are located on two opposite display surfaces. In addition, in order to facilitate the bending of the display device, the bending region only includes the flexible substrate 30 and the package stack thereof, and does not include a display function layer, so that the display module is not affected.
With continuing reference to fig. 2 and fig. 3, an embodiment of the present application further provides a terminal device, where the terminal device is an unfolded terminal device, where the unfolded terminal device refers to a terminal device whose display area is not foldable. The terminal equipment comprises a middle frame 300 and any one of the display devices; the bending area of the substrate is bent along the side wall of the middle frame 300, one side wall of the middle frame 300 is provided with an arc-shaped arc guide surface 301, the substrate of the display device is bent along the arc guide surface 301, so that the display device can be bent along a set angle, and the stability of the substrate can be improved through the support of the arc guide surface 301. With reference to fig. 3, the first display module 10 and the second display module 20 are respectively arranged on two opposite sides of the middle frame 300, so that the terminal device can have two display modules with opposite display directions, and the two display modules are driven synchronously by the same driving circuit, so that the two display modules can display synchronously; adopt simultaneously one side at one of them display module group place to set up camera module group 90 for the module of making a video recording of this side can carry out functions such as video, take a picture, and the display module group of opposite side only need show, thereby makes the effect that first display module group 10 one side can accomplish narrow frame or no frame. Providing the effect of the user when in use.
In order to facilitate understanding of the terminal device provided by the embodiment of the application, the embodiment of the application also provides a preparation method of the terminal device.
Step 1: the substrate is prepared first, and the preparation process is mature and does not need to be detailed. When the substrate is prepared, the number of the bearing areas on the substrate is two, and the two bearing areas respectively correspond to the two display areas: AA1 and AA2, and AA1 and AA2 are for cell phone front and back displays, respectively. Various driving circuits are arranged between the two AA areas, the area is a wiring area, the power supply socket can be bent at the area, and power supply socket avoiding holes can be designed according to the requirements of the whole machine.
Step 2: and (5) processing the module. Set gradually organic light emitting diode layer, film packaging layer, polarisation lamella and touch-control layer, apron on the base plate to going up each layer structure and cutting in proper order, forming double screen module: the display device comprises a first display module and a second display module. The second display module assembly will assemble camera module windowing, rearmounted fingerprint as required, and fingerprint windowing, the light environment light of being close to windowing etc. under the screen can be designed as required to first display module assembly.
And step 3: and (6) assembling the whole machine. And designing a proper whole machine framework and a proper technological process so as to assemble the double-screen display module on the whole machine. One scheme is to assemble all parts except the screen on the two sides of the middle frame and glue the upper side and the lower side of the middle frame, then lock the display flexible circuit board and the fingerprint sensor of the rear screen on the main board, align the second display module to the rear part of the mobile phone, bend the second display module at the bending part, bend the first display module to the front part of the mobile phone and align the first display module to the front part of the mobile phone. And then pre-pressing and maintaining the pressure of the first display module and the second display module, and assembling the lower shell piece. And finally, performing a waterproof process of the periphery joint filling glue.
