Referring to fig. 2, fig. 2 is a schematic view of a foldable display panel 20 according to a first embodiment of the invention. The first embodiment of the present invention provides a foldable display panel 20, which includes a substrate 21, a thin film transistor layer (not shown), a first driving integrated circuit 2116, and a second driving integrated circuit 2126, wherein the substrate 21 has a first folding region 211 and a second folding region 212, the first folding region 211 has a first display region 2112 and a first non-display region 2114, the second folding region 212 has a second display region 2122 and a second non-display region 2124, the first folding region 211 and the second folding region 212 are folded around a first folding axis 22, that is, the first display region 2112 and the second display region 2122 are folded around the first folding axis 22, the first non-display region 2114 and the second non-display region 2124 are folded around the first folding axis 22, and the first folding axis 22 divides the substrate 21 into the first folding region 211 having the first display region 2112 and the first non-display region 2114, and the second folding region 211 having the second display region 2122 and the first non-display region 2114, and the second folding region 2122 and the second non-display region 2124 And a second folding area 212 at a side of the second non-display area 2124. In addition, the thin film transistor layer is correspondingly disposed on the substrate 21, and includes a plurality of pixel driving circuit units (not shown) for driving light emitting pixels.

That is, the first driving integrated circuit 2116 and the second driving integrated circuit 2126 are disposed in different folding regions.
In this embodiment, a plurality of scan lines 213 and a plurality of data lines 214 are disposed in the display region (i.e., the first display region 2112 and the second display region 2122), wherein the plurality of scan lines 213 are arranged along a first direction, and the arrangement direction thereof penetrates through the first display region 2112 and the second display region 2122.

In one embodiment, the first direction and the second direction are perpendicular to each other, for example, the first direction is a row direction, the second direction is a column direction, that is, the plurality of scan lines 213 are arranged along the row direction, and the plurality of data lines 214 are arranged along the column direction.
In this embodiment, the first driving integrated circuit 2116 and the second driving integrated circuit 2126 may be located in the non-display region at the same end in the column direction in different folding regions. Specifically, the first driving integrated circuit 2116 and the second driving integrated circuit 2126 may be positioned at a lower side of the first display region 2112 and a lower side of the second display region 2122, respectively; alternatively, the first driver integrated circuit 2116 and the second driver integrated circuit 2126 may be located above the first display region 2112 and above the second display region 2122, respectively. In another embodiment, the first driving integrated circuit 2116 and the second driving integrated circuit 2126 may be located at different ends in the column direction in different folding regions. Specifically, the first driving integrated circuit 2116 is located at a lower side of the first display region 2112, and the second driving integrated circuit 2126 is located at an upper side of the second display region 2122; alternatively, the first driving integrated circuit 2116 is located on an upper side of the first display region 2112, and the second driving integrated circuit 2126 is located on a lower side of the second display region 2122.

The second driving integrated circuit 2126 may be electrically connected to the pixel driving circuit units in the second display region 2122 through corresponding data lines (not labeled) in the second display region 2122 to provide corresponding data signals of the second display region 2122.
In this embodiment, the foldable display panel 20 further includes at least one array of Gate On Array (GOA) circuits disposed on the substrate 21 and located on at least one side of the first folding axis 22, that is, the GOA circuits may include one GOA circuit or two GOA circuits, and in the case of the one GOA circuit, the GOA circuits may be exemplarily located in a non-display area on the left side of the first display area 2112 or a non-display area on the right side of the second display area 2122, and in the case of the two GOA circuits, the GOA circuits may be exemplarily located in a non-display area on the left side of the first display area 2112 and a non-display area on the right side of the second display area 2122, respectively, where the non-display area is an area other than the first non-display area 2114 and the second non-display area 2124. For the purpose of explaining the present invention, the present invention is described with two GOA circuits as a preferred embodiment, and the two GOA circuits are the first GOA circuit 2151 and the second GOA circuit 2152, respectively. The first GOA circuit 2151 is electrically connected to the first driver ic 2116 disposed on the same side of the first display area 2112 with respect to the first folding axis 22, and the second GOA circuit 2152 is electrically connected to the second driver ic 2126 disposed on the same side of the second GOA circuit 2152 with respect to the first folding axis 22, as shown in fig. 2. And the first and second GOA circuits 2151 and 2152 are electrically connected to the pixel driving circuit unit in the display area via corresponding scan lines disposed in the display area, and at this time, a corresponding scan signal required for light emitting display can be provided by at least one of the first and second driving integrated circuits 2116 and 2126. That is, if the driving capability of the driving integrated circuit is strong enough, only one driving integrated circuit may be used to transmit the corresponding scan signal to the display area.
In this embodiment, in order to achieve higher resolution, the first driving integrated circuit 2116 and the second driving integrated circuit 2126 are connected in series in a cascade (cascade) scheme, so that two driving integrated circuits can be simultaneously used to drive the foldable display panel 20. Specifically, the first driving integrated circuit 2116 and the second driving integrated circuit 2126 are electrically connected to each other and transmit a first synchronization signal therebetween, where the first synchronization signal is used to control the first driving integrated circuit 2116 and the second driving integrated circuit 2126, so as to perform synchronous driving control on the plurality of pixel driving circuit units.
In combination with the above, when the first folding region 211 and the second folding region 212 are unfolded around the first folding axis 22, and at this time, the first display region 2112 and the second display region 2122 are both in a light emitting display state, at this time, the first driving integrated circuit 2116 outputs a corresponding data signal to the first display region 2112, and due to the synchronous driving control of the first synchronous signal, the second driving integrated circuit 2126 outputs a corresponding data signal to the second display region 2122 at the same time, and at least one of the first driving integrated circuit 2116 and the second driving integrated circuit 2126 synchronously outputs a corresponding scanning signal to the display region. In addition, when the first folding region 211 and the second folding region 212 are folded around the first folding axis 22 (i.e. in a folding state), one of the first display region 2112 and the second display region 2122 is in a light emitting display state and the other is in a dark screen state, for example, the first display region 2112 is in a light emitting display state and the second display region 2122 is in a dark screen state, the first driving integrated circuit 2116 outputs a corresponding data signal to the first display region 2112, and due to synchronous driving control of the first synchronous signal, the second driving integrated circuit 2126 does not need to output a corresponding data signal to the second display region 2122 synchronously, and at least one of the first driving integrated circuit 2116 and the second driving integrated circuit 2126 outputs a corresponding scanning signal to the display region synchronously. In this example, the second driving ic 2126 achieves the saving effect because it is not required to output the corresponding data signal to the second display region 2122. Further, if the corresponding scan signal is sent by the first driving ic 2116, the second driving ic 2116 may stop driving, and the second display area 2122 is in a standby state, and when the second driving ic 2126 receives a wake-up signal pulse (for example, when the first folding area 211 and the second folding area 212 are unfolded around the first folding shaft 22 again), the second display area 2122 is changed from the standby state to a normal operation mode of light-emitting display. It is understood that the first display region 2112 in a dark screen state and the second display region 2122 in a light emitting display state can be described as above, and details are not repeated here.
In this embodiment, the first driving integrated circuit 2116 is responsible for corresponding data signals transmitted to the first display region 2112, and the second driving integrated circuit 2126 is responsible for corresponding data signals transmitted to the second display region 2122. As can be seen, the driving ics in different folding regions can independently perform one-to-one control operation on the display regions corresponding to the driving ics, that is, the first driving ic 2116 in the first folding region 211 can control the light emitting display of the first display region 2112, and the second driving ic 2126 in the second folding region 212 can control the light emitting display of the second display region 2122, thereby achieving the effect of saving power consumption. It is understood that the corresponding scan signal for light emitting display is provided by at least one of the first driving integrated circuit 2116 and the second driving integrated circuit 2126.

The plurality of data lines 314 are arranged in a second direction intersecting the first direction, and are disposed parallel to or not intersecting the first folding axis 32 and the second folding axis 33. In one embodiment, the first direction and the second direction are perpendicular to each other, for example, the first direction is a row direction, the second direction is a column direction, that is, the plurality of scan lines 313 are arranged along the row direction, and the plurality of data lines 314 are arranged along the column direction.

As described in the first embodiment of the present invention, further description is omitted here.
In this embodiment, the first driving integrated circuit 3116 can be electrically connected to the pixel driving circuit units in the first display area 3112 through corresponding data lines (not labeled) in the first display area 3112 to provide corresponding data signals of the first display area 3112. The second driving integrated circuits 3126 may be electrically connected to the pixel driving circuit units in the second display region 3122 through corresponding data lines (not labeled) in the second display region 3122 to provide corresponding data signals of the second display region 3122, and the third driving integrated circuits 3156 may be electrically connected to the pixel driving circuit units in the third display region 3152 through corresponding data lines (not labeled) in the third display region 3152 to provide corresponding data signals of the third display region 3152.

Specifically, the first driver integrated circuit 3116, the second driver integrated circuit 3126, and the third driver integrated circuit 3156 are electrically connected to each other, and transmit a second synchronization signal therebetween, the second synchronization signal being used to control the first driver integrated circuit 3116, the second driver integrated circuit 3126, and the third driver integrated circuit 3156, and perform synchronous driving control of the plurality of pixel driver circuit units.
In combination with the above, when the first folding area 311 and the second folding area 312 are unfolded around the first folding axis 22, and the second folding zone 312 and the third folding zone 315 are unfolded around the second folding axis 33, at this time, the first display region 3112, the second display region 3122, and the second display region 3152 are all in a light-emitting display state, and the first driving integrated circuit 3116 outputs a corresponding data signal to the first display region 3112, and, due to the synchronous driving control of the second synchronous signal, the second driving integrated circuit 3126 simultaneously outputs a corresponding data signal to the second display region 3122, the third driving integrated circuit 3156 simultaneously outputs a corresponding data signal to the third display region 3152, and at least one of the first driving integrated circuit 3116 and the third driving integrated circuit 3156 outputs a corresponding scan signal to the display region in synchronization. In addition, when the first folding region 311 and the second folding region 312 are folded around the first folding axis 32 (i.e. in a folding state), one of the first display region 3112 and the second display region 3122 is displayed in a light-emitting manner, and the other is in a dark-screen state, for example, the first display region 3112 is in a dark-screen state and the second display region 3122 and the third display region 3152 are displayed in a light-emitting manner (i.e. the second folding region 312 and the third folding region 315 are simultaneously unfolded around the second folding axis 33), the first driving integrated circuit 3116 does not output a corresponding data signal to the first display region 3112, and due to the synchronous driving control of the second synchronous signal, the second driving integrated circuit 3126 and the third driving integrated circuit 3156 output a corresponding data signal to the second display region 3122 and the third display region 3152, respectively, and at least one of the first driving integrated circuit 3116 and the third driving integrated circuit 3156 outputs a corresponding scan signal to the display region in synchronization. In this example, the first driving integrated circuit 3116 achieves power saving by not outputting corresponding data signals to the first display region 3112. Further, if the corresponding scan signal is sent by the third driving integrated circuit 3156, the first driving integrated circuit 3116 may stop driving, and the first display area 3122 is in a standby state, at this time, when the first driving integrated circuit 3126 receives a wake-up signal pulse (for example, when the first folding area 311 and the second folding area 312 are unfolded around the first folding axis 32 again), the first display area 3122 is changed from the standby state to a normal operation mode of light-emitting display. It is understood that the first display region 3112 and the second display region 3122 are in a light emitting display mode, and the third display region 3152 is in a dark screen mode, which is not described herein again. Further, when the first folding region 311, the second folding region 312, and the third folding region 315 are all in the folded state, at least one of the first display region 3112, the second display region 3122, and the third display region 3152 is in a dark screen state, which may also be described as above, and will not be described herein.
In this embodiment, the first driver ic 3116 is responsible for the corresponding data signals transmitted to the first display region 3112, the second driver ic 3126 is responsible for the corresponding data driving signals transmitted to the second display region 3112, and the third driver ic 3156 is responsible for the corresponding data signals transmitted to the third display region 3152. As can be seen, the driving ics in different folding regions can independently perform one-to-one control operation on the display regions corresponding to the driving ics, that is, the first driving ic 3116 in the first folding region 311 can control the light emitting display of the first display region 3112, the second driving ic 3126 in the second folding region 312 can control the light emitting display of the second display region 3122, and the third driving ic 3156 in the third folding region 315 can control the light emitting display of the third display region 3152, so as to achieve the effect of saving power consumption. It is understood that the corresponding scan signal for light emitting display is provided by at least one of the first driving integrated circuit 3116 and the third driving integrated circuit 3156. For further details of the second embodiment of the present invention, reference may be made to the first embodiment of the present invention, which will not be described herein again.
It should be understood that the present invention has many folding possibilities, that is, the light emitting display and the dark screen state of the display region are not limited to the above exemplary description, and the present specification describes two folding regions and three folding regions, which should not be construed as a limitation to the present invention, and the present invention may include at least more than three folding regions, without departing from the spirit of the present invention, which is the protection scope of the present invention.
Based on the above, the driving integrated circuits are disposed in different folding areas, and are electrically connected to the pixel driving circuit units in the display areas corresponding to the driving integrated circuits through the corresponding data lines to provide corresponding data signals of the display areas, so that one-to-one display control over the display areas is achieved, and when at least one display area in the folding display panel does not need to be displayed in a light-emitting manner, the driving integrated circuits disposed corresponding to the display areas can stop driving, thereby reducing waste of power consumption. Further, the present invention can be applied to a display panel having three or more display regions. Therefore, the invention has obvious progress and obvious advantages.
Although the present invention has been described with reference to the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope of the invention as defined by the appended claims.
