In the first scanning, assuming the scanning time t1, half of the picture a to be photographed may be scanned, that is, corresponding to the first region S1, and in the second scanning, the other half of the picture a to be photographed that is not scanned may be scanned, that is, corresponding to the second region S2. This corresponds to a split scan, and each scan results in a picture in a different area. Specifically, the scanning can be performed more times, in this case, during each scanning, the image pickup assembly scans 1/n area of the picture to be photographed each time, n is the number of scanning times, and the plurality of areas finally form the whole picture a.

In the first control time period t1, the first area S1 of the scan screen is scanned.

After the scanning of the first area S1 is completed, in the second control timing segment t2, the first backlight module is turned on, the camera shooting assembly is turned off, and meanwhile, the data corresponding to the scanned first area S1 is subjected to image preview display, and the obtained data is stored.

After the first preview display is completed, the screen in the first area S1 corresponding to the whole screen is obtained at this time.

And after the picture corresponding to the first area S1 is shot, shooting the picture A for the second time. At this time, in the second shooting process, the corresponding picture in the second area S2 of the picture a is scanned and shot, and then the above steps are repeated, and the picture in the second area S2 is displayed as a preview and stored. The first area S1 obtained by the first scanning and the second area S2 obtained by the second scanning are different areas, and the first area S1 and the second area S2 may not overlap or partially overlap. When the overlapped area exists, the area of the overlapped area is less than one tenth of the area of the picture taken each time. Therefore, the problem of incompatibility in the last overlapping process when shooting for multiple times in the same area can be effectively prevented, and the shooting effect of the display panel is effectively ensured.

After the shooting of the second area S2 of the picture A is finished, the preview display is carried out, wherein, in the preview display, because the data corresponding to the first area S1 is stored in the storage module, at the moment, the data is called from the storage module and is previewed and displayed together with the data corresponding to the second area S2, so that the picture of the whole picture A is obtained.

In the embodiment of the application, in the shooting and imaging process, the whole picture can be divided into a plurality of units by scanning for a plurality of times and scanning different areas each time, and each small unit is shot, exposed and imaged respectively, so that the exposure time of the picture can be effectively prolonged, and the shooting effect of the picture is improved.

Therefore, in each scanning process, partial area of the camera shooting assembly can be scanned, for example, the upper half part of the camera shooting assembly works normally, and the picture is scanned.

Furthermore, in the embodiment of the present application, the picture to be photographed may also be directly divided, for example, the picture to be photographed is divided into a plurality of different areas, and a specific area is scanned during each scanning until all the divided areas are scanned. The manner is the same as the above-mentioned multiple scanning, and the description is omitted here.

In the embodiment of the present application, the time lengths of the first control timing segment t1 and the second control timing segment t2 are the same, and both may be set to 8.3ms. In the embodiment of the present application, compared to the timing diagram in fig. 3, since the exposure process is performed on the frame for 2 times, when the entire frame is completely shot, the total exposure time is twice as long as that in fig. 3. Thereby effectual display module's the effect of making a video recording that has improved.

Further, as shown in fig. 7, fig. 7 is a schematic flow chart corresponding to the image pickup driving method of the display module according to the embodiment of the present application.

The digital signal passes through the digital signal processor again, and the processed data is transmitted to a control chip of the display module or a corresponding processor, and a required picture is formed.

In the embodiment of the application, when the picture is shot, the picture is scanned and exposed for multiple times, data obtained by exposure is stored, areas exposed each time are different, after the last exposure is finished, the data obtained by multiple times of exposure is displayed, and the picture shot in the embodiment of the application is finally formed.
