a
at least two driving modules 20, which are disposed on one of the frames, and are arranged in parallel along a length direction of the frame, and are respectively used for driving different display regions of the display panel;
and a
The
As described above, at least one frame may be disposed around the display panel, and at least two driving modules 20 may be disposed on one frame of the at least one frame. The frame of the display panel includes a horizontal frame (an upper frame and/or a lower frame), and each driving module 20 may be disposed on the horizontal frame, and at this time, the driving modules 20 may be disposed on the horizontal frame in a horizontal direction, respectively. For example, as shown in fig. 1, two driving modules 20 with a rectangular front view are arranged at the transverse lower frame of the display screen, and the two driving modules 20 can be arranged side by side along the lower frame, for example, the short sides of the two driving modules are adjacent and the long sides are parallel to the lower frame. Alternatively, in other embodiments, the driving modules may also be disposed on a vertical frame of the display screen, and in this case, the driving modules 20 may be disposed on the vertical frame in a vertical arrangement. The number of the driving modules and the frame on which the driving modules are arranged are not particularly limited in the embodiments of the present disclosure, and those skilled in the art can set the driving modules according to different requirements.
In addition, the display panel of the embodiment of the present disclosure may be divided into a plurality of sub display regions, each sub display region is correspondingly driving-connected to one driving module, and performs corresponding display by the driving signal transmitted by the connected driving module 20. For example, when two driving modules 20 are included, the display area of the display panel may be divided into two sub-display areas, i.e., a left sub-display area and a right sub-display area, or two sub-display areas, i.e., an upper sub-display area and a lower sub-display area, and each driving module 20 is respectively connected to one sub-display area to control the display state of the connected sub-display area.
Or, in other embodiments, the display panel may also include three driving modules 20, the display area of the display panel may also be correspondingly divided into three sub-display areas, and each driving module 20 is correspondingly connected to the corresponding sub-display area to drive the corresponding sub-display area to display. The number of the driving modules and the dividing manner of the display area are not particularly limited in the embodiments of the present disclosure, and the embodiments of the present disclosure may be regarded as the embodiments of the present disclosure as long as the driving modules can be connected to the corresponding display areas.

In the conventional scheme, one driving device is usually adopted to drive the display of the whole display screen, so that the driving device has a large volume, and the frame width of the display screen cannot be reduced. Meanwhile, the driving device needs to be connected with the pixel points of each row and each column of the whole display area, so that the connected leads are large and long, and a plurality of leads also need to occupy more space positions, and the width of the frame of the display screen is finally wide due to the reasons. In this regard, the embodiment of the present disclosure employs two or more driving modules arranged in parallel on the frame to reduce the volume of each driving module, and shorten the longitudinal length b of each driving module 20 shown in fig. 1, and at the same time, each driving module 20 is connected to the corresponding sub-display region in a driving manner, so as to shorten the length of the lead 23 used for driving connection, and reduce the width range of the frame occupied by the lead, such as the longitudinal length a shown in fig. 1.
Meanwhile, since the connecting end of the display element in the sub-display region is located on the bottom surface of the display panel, in order to further shorten the length of the lead 23 used for connecting the driving module 20 and the sub-display region, in the embodiment of the present disclosure, the driving signal terminal 22 (driving signal output terminal) of each driving module is disposed at the bottom of the driving module, and each driving signal terminal 22 is connected to the display element in the display region driven correspondingly, the bottom surface of the driving module 20 is a surface where the driving module 20 is attached to the
The embodiment of the disclosure shortens the longitudinal length of each driving module by increasing the number of the driving modules, reduces the width of the frame of the display screen occupied by the driving modules, sets the driving signal ends of the driving modules at the bottom of the driving modules, and enables the driving modules to be respectively connected with the sub-display areas closest to the driving modules, thereby reducing the length of the lead wires used for driving connection, simplifying the space range occupied by stacking numerous and complex lead wires, and finally achieving the purpose of realizing the narrow frame of the display screen.

In addition, in the embodiment of the present disclosure, the driving modules 20 controlling the adjacent sub-display regions may be disposed adjacently, or may be connected through a synchronization signal terminal, where when each sub-display region is controlled and displayed, after one driving module 20 completes the display control of its sub-display region, the synchronization signal may be sent to the driving module 20 corresponding to the adjacent sub-region, and after the driving module 20 receives the synchronization signal, the driving module 20 may execute the display control of the corresponding sub-display region according to the received driving signal. That is, the driving module 20 in the embodiment of the present disclosure may send the synchronization signal to the next driving module according to the driving sequence of each sub-display region, so that the driving display of the sub-display regions may be completed sequentially.
