本发明涉及显示技术领域，尤其涉及一种降低驱动集成电路功耗的折叠显示面板以及折叠显示装置。

随着中大尺寸的折叠显示面板发展，对驱动集成电路（DIC）所能支持的分辨率要求越来越高，单颗DIC已经不能满足对应需求，因此级联方案的DIC逐渐成为主流，通过联级的方式可以同时使用两颗或者两颗以上的DIC来驱动折叠显示面板，但驱动集成电路的功耗却也成了必须被解决的问题。
请参照图1，图1为现有的折叠显示面板10的示意图。其包括有薄膜晶体管阵列基板11，所述薄膜晶体管阵列基板11具有第一显示区112、第二显示区114、设置于非显示区116的第一驱动集成电路122与第二驱动集成电路124，其中第一显示区112与非显示区116属于第一折叠区（未标示），第二显示区114属于第二折叠区（未标示），所述第一折叠区和所述第二折叠区绕折叠轴12折叠设置。当所述第一折叠区和所述第二折叠区以所述折叠轴12为轴心展开时，所述第一显示区112以及所述第二显示区114会发光显示，此时第一驱动集成电路122以及第二驱动集成电路124均会提供扫描信号以及数据信号，使得所述第一显示区112以及所述第二显示区114（即显示区域）中的像素驱动电路单元（未标示）得以被驱动而发光显示。此外，当所述第一折叠区和所述第二折叠区以所述折叠轴12为轴心折叠时，所述第一显示区112以及所述第二显示区114的其中一区会发光显示，另一区则是暗屏的状态，此时第一驱动集成电路122以及第二驱动集成电路124均仍然在显示区域中持续提供扫描信号以及数据信号，相对于展开状态，所述第一驱动集成电路122以及所述第二驱动集成电路124的功耗并没有相对减少，因此造成功耗上的浪费。

请参照图2，图2为本发明第一实施例的折叠显示面板20示意图。本发明第一实施例提供一种折叠显示面板20，其包括有基板21、薄膜晶体管层（未图示）、第一驱动集成电路2116、以及第二驱动集成电路2126，所述基板21具有第一折叠区211与第二折叠区212，所述第一折叠区211具有第一显示区2112以及第一非显示区2114，所述第二折叠区212具有第二显示区2122以及第二非显示区2124，所述第一折叠区211与所述第二折叠区212绕第一折叠轴22折叠设置，即所述第一显示区2112和所述第二显示区2122绕所述第一折叠轴22折叠设置，所述第一非显示区2114和所述第二非显示区2124绕所述第一折叠轴22折叠设置，也即所述第一折叠轴22将所述基板21分成具有所述第一显示区2112和所述第一非显示区2114一侧的第一折叠区211以及具有第二显示区2122和所述第二非显示区2124一侧的第二折叠区212。另外，所述薄膜晶体管层对应设置在所述基板21上，并且其包括有用以驱动发光像素的多个像素驱动电路单元（未图示）。所述第一驱动集成电路2116设置在所述基板21上的所述第一非显示区2114，所述第二驱动集成电路2126设置在所述基板21上的所述第二非显示区2124。也就是说所述第一驱动集成电路2116以及所述第二驱动集成电路2126被设置于不同的折叠区中。
在本实施例中，显示区域中（即所述第一显示区2112和所述第二显示区2122）设置有多条扫描线213以及多条数据线214，其中所述多条扫描线213沿第一方向排列，其排列方向贯穿所述第一显示区2112与所述第二显示区2122。所述多条数据线214沿与所述第一方向相交的第二方向排列，并且其与所述第一折叠轴22为平行或者不相交设置。于一实施例中，所述第一方向与所述第二方向相互垂直，例如所述第一方向为行方向，所述第二方向为列方向，即所述多条扫描线213为沿行方向排列，所述多条数据线214为沿列方向排列。
在本实施例中，所述第一驱动集成电路2116以及所述第二驱动集成电路2126可以位于不同折叠区中的列方向上的同一个末端的非显示区。具体地，所述第一驱动集成电路2116以及所述第二驱动集成电路2126可以分别位于所述第一显示区2112的下侧以及所述第二显示区2122的下侧；又或者，所述第一驱动集成电路2116以及所述第二驱动集成电路2126可以分别位于所述第一显示区2112的上侧以及所述第二显示区2122的上侧。于另一实施例中，所述第一驱动集成电路2116以及所述第二驱动集成电路2126可以位于不同折叠区中的列方向上的相异末端。具体地，所述第一驱动集成电路2116位于所述第一显示区2112的下侧，而所述第二驱动集成电路2126位于所述第二显示区2122的上侧；又或者，所述第一驱动集成电路2116位于所述第一显示区2112的上侧，而所述第二驱动集成电路2126位于所述第二显示区2122的下侧。
在本实施例中，所述第一驱动集成电路2116可以通过所述第一显示区2112中的相应数据线（未标示）与所述第一显示区2112中的像素驱动电路单元电连接，以提供所述第一显示区2112的相应数据信号。所述第二驱动集成电路2126可以通过所述第二显示区2122中的相应数据线（未标示）与所述第二显示区2122中的像素驱动电路单元电连接，以提供所述第二显示区2122的相应数据信号。
在本实施例中，所述折叠显示面板20还包括有至少一阵列基板栅极驱动（gate on array, GOA）电路，其设置在所述基板21上且位于所述第一折叠轴22至少一侧，也就是说所述GOA电路可以包括有一路GOA电路，也可以包括有两路GOA电路，当为一路GOA电路时，其示例性地可以位于所述第一显示区2112左侧的非显示区域或是位于所述第二显示区2122右侧的非显示区域，当为两路GOA电路时，其示例性地可以分别位于所述第一显示区2112左侧的非显示区域以及所述第二显示区2122右侧的非显示区域，所述非显示区域为除了所述第一非显示区2114以及所述第二非显示区2124之外的区域。为了解释本发明，本发明以两路GOA电路作为优选实施例来做说明，并且所述两路GOA电路分别为第一GOA电路2151以及第二GOA电路2152。所述第一GOA电路2151与相对于所述第一折叠轴22、设置在与所述第一显示区2112同一侧的所述第一驱动集成电路2116电连接，所述第二GOA电路2152与相对于所述第一折叠轴22、设置在与所述第二GOA电路2152同一侧的所述第二驱动集成电路2126电连接，如图2所示。并且所述第一GOA电路2151以及第二GOA电路2152分别通过设置于显示区域中的相应扫描线与显示区域中的像素驱动电路单元电连接，此时发光显示所需要的相应扫描信号可以由所述第一驱动集成电路2116和所述第二驱动集成电路2126中的至少一个提供。也就是说，若驱动集成电路的驱动能力够强时，可以仅使用一个驱动集成电路对所述显示区域发送相应扫描信号即可。
在本实施例中，为了实现更高的分辨率，所述第一驱动集成电路2116以及所述第二驱动集成电路2126以联级（cascade）的方案进行串接，使其可以同时使用两颗驱动集成电路来驱动折叠显示面板20。具体地，所述第一驱动集成电路2116与所述第二驱动集成电路2126彼此电连接，并且相互之间传输第一同步信号，所述第一同步信号用于控制所述第一驱动集成电路2116与所述第二驱动集成电路2126，对所述多个像素驱动电路单元进行同步驱动控制。
结合上述，当所述第一折叠区211与所述第二折叠区212以第一折叠轴22为轴心展开时，此时所述第一显示区2112与所述第二显示区2122均为发光显示的状态，此时所述第一驱动集成电路2116会对所述第一显示区2112输出相应数据信号，并且由于所述第一同步信号的同步驱动控制，所述第二驱动集成电路2126会同时对所述第二显示区2122输出相应数据信号，并且所述第一驱动集成电路2116和所述第二驱动集成电路2126中的至少一个同步地对显示区域输出相应扫描信号。另外，当所述第一折叠区211与所述第二折叠区212以第一折叠轴22为轴心折叠时（即处于折叠状态），此时所述第一显示区2112与所述第二显示区2122中的其中一个会发光显示，而另一个则为暗屏的状态，以下以所述第一显示区2112发光显示以及所述第二显示区2122为暗屏的状态为例，此时所述第一驱动集成电路2116会对所述第一显示区2112输出相应数据信号，并且由于所述第一同步信号的同步驱动控制，所述第二驱动集成电路2126同步地不需要对所述第二显示区2122输出相应数据信号，而所述第一驱动集成电路2116和所述第二驱动集成电路2126中的至少一个同步地对显示区域输出相应扫描信号。在此例子中，所述第二驱动集成电路2126由于不需要对所述第二显示区2122输出相应数据信号而达到节省的功效。进一步地，若此时的相应扫描信号为由所述第一驱动集成电路2116发送，则所述第二驱动集成电路2116可以停止驱动，而所述第二显示区2122则处于待机状态，当所述第二驱动集成电路2126接收到唤醒信号脉冲时（例如所述第一折叠区211与所述第二折叠区212再次以所述第一折叠轴22为轴心展开时），所述第二显示区2122会由待机状态转变为发光显示的正常工作模式。可以理解的是，所述第一显示区2112为暗屏的状态以及所述第二显示区2122为发光显示的情况可以使用上述来作说明，在此不加以赘述。
在本实施例中，所述第一驱动集成电路2116负责传送给所述第一显示区2112的相应数据信号，所述第二驱动集成电路2126负责传送给所述第二显示区2122的相应数据信号。可见，位于不同折叠区中的驱动集成电路可以独立对与其对应的显示区进行一对一的控制操作，即所述第一折叠区211中的所述第一驱动集成电路2116可以控制所述第一显示区2112的发光显示，所述第二折叠区212中的所述第二驱动集成电路2126可以控制所述第二显示区2122的发光显示，从而达到节省功耗的效果。可以理解的是，此时用以发光显示的相应扫描信号会由所述第一驱动集成电路2116和所述第二驱动集成电路2126中的至少一个提供。
请参照图3，图3为本发明第二实施例的折叠显示面板30示意图。本发明不仅可以使用在具有两个折叠区的折叠显示面板，更可以使用于三个折叠区的折叠显示面板。本发明的第二实施例为具有三个折叠区的折叠显示面板30，其相较于上述的第二实施例，基板31还包括有第三折叠区315。所述第三折叠区315设置于第二折叠区312远离第一折叠区311的一侧，所述第三折叠区315具有第三显示区3152以及第三非显示区3154，并且所述第二折叠区312与所述第三折叠区315绕第二折叠轴33折叠设置，即所述第三显示区3152和所述第二显示区3122绕所述第二折叠轴33折叠设置，所述第三非显示区3154和所述第二非显示区3124绕所述第二折叠轴33折叠设置，也即所述第二折叠轴33将所述基板31分成具有所述第二显示区3122和所述第二非显示区3124一侧的第二折叠区311以及具有第三显示区3152和所述第三非显示区3154一侧的第三折叠区315。所述第三驱动集成电路3156设置在所述基板31上的所述第三非显示区3154。也就是说第一驱动集成电路3116、第二驱动集成电路3126、以及所述第三驱动集成电路3156被设置于不同的折叠区中。
在本实施例中，显示区域（即第一显示区3112、第二显示区3122、以及所述第三显示区3152）设置有多条扫描线313以及多条数据线314，其中所述多条扫描线313沿第一方向排列，其排列方向贯穿所述第一显示区3112、所述第二显示区3122、以及所述第三显示区3152。所述多条数据线314沿与所述第一方向相交的第二方向排列，并且其与所述第一折叠轴32以及所述第二折叠轴33为平行或者不相交设置。于一实施例中，所述第一方向与所述第二方向相互垂直，例如所述第一方向为行方向，所述第二方向为列方向，即所述多条扫描线313为沿行方向排列，所述多条数据线314为沿列方向排列。
在本实施例中，所述第一驱动集成电路3116、所述第二驱动集成电路3126、以及所述第三驱动集成电路3156可以分别位于不同折叠区中的列方向上的同一个末端的非显示区，也可以位于列方向上的相异末端。如本发明第一实施例所述，在此不加以赘述。
在本实施例中，所述第一驱动集成电路3116可以通过所述第一显示区3112中的相应数据线（未标示）与所述第一显示区3112中的像素驱动电路单元电连接，以提供所述第一显示区3112的相应数据信号。所述第二驱动集成电路3126可以通过所述第二显示区3122中的相应数据线（未标示）与所述第二显示区3122中的像素驱动电路单元电连接，以提供所述第二显示区3122的相应数据信号，所述第三驱动集成电路3156可以通过所述第三显示区3152中的相应数据线（未标示）与所述第三显示区3152中的像素驱动电路单元电连接，以提供所述第三显示区3152的相应数据信号。
在本实施例中，所述折叠显示面板30还包括有至少一阵列基板栅极驱动（gate on array, GOA）电路，其设置在所述基板31上且位于所述第一折叠轴32或者所述第二折叠轴33的至少一侧，也就是说所述GOA电路可以包括有一路GOA电路，也可以包括有两路GOA电路，当为一路GOA电路时，其示例性地可以位于所述第一显示区3112左侧的非显示区域或是位于所述第三显示区3152右侧的非显示区域，当为两路GOA电路时，其示例性地可以分别位于所述第一显示区3112左侧的非显示区域以及所述第三显示区3152右侧的非显示区域，所述非显示区域为除了所述第一非显示区3114、所述第二非显示区3124、以及所述第三非显示区3154之外的区域。为了解释本发明，本发明以两路GOA电路作为优选实施例来做说明，并且所述两路GOA电路分别为第一GOA电路3161以及第二GOA电路3162。所述第一GOA电路3161与相对于所述第一折叠轴32（或者相对于所述第二折叠轴33）、设置在与所述第一GOA电路3161同一侧的所述第一驱动集成电路3116电连接，所述第二GOA电路3152与相对于所述第二折叠轴33（或者相对于所述第一折叠轴32）、设置在与所述第二GOA电路3152同一侧的所述第三驱动集成电路3156电连接，如图3所示。并且所述第一GOA电路3161以及所述第二GOA电路3162分别通过显示区域的相应扫描线与显示区域中的像素驱动电路单元电连接，此时发光显示所需要的相应扫描信号可以由所述第一驱动集成电路3116以及所述第三驱动集成电路3156中的至少一个提供。也就是说，若驱动集成电路的驱动能力够强时，可以仅使用一个驱动集成电路对所述显示区域发送相应扫描信号即可。可以理解的是，由于所述第二驱动集成电路3126并未与GOA电路连接，因此所述第二显示区3122发光显示所需要的相应扫描信号为由所述第一驱动集成电路3116以及所述第三驱动集成电路3156中的至少一个提供。
在本实施例中，为了实现更高的分辨率，所述第一驱动集成电路3116、所述第二驱动集成电路3126、以及所述第三驱动集成电路3156以联级（cascade）的方案进行串接，使其可以同时使用三颗驱动集成电路来驱动折叠显示面板30。具体地，所述第一驱动集成电路3116、所述第二驱动集成电路3126、以及所述第三驱动集成电路3156彼此电连接，并且相互之间传输第二同步信号，所述第二同步信号用于控制所述第一驱动集成电路3116、所述第二驱动集成电路3126、以及所述第三驱动集成电路3156，对所述多个像素驱动电路单元进行同步驱动控制。
结合上述，当所述第一折叠区311与所述第二折叠区312以第一折叠轴22为轴心展开，并且所述第二折叠区312与所述第三折叠区315以第二折叠轴33为轴心展开时，此时所述第一显示区3112、所述第二显示区3122、以及所述第二显示区3152均为发光显示的状态，此时所述第一驱动集成电路3116会对所述第一显示区3112输出相应数据信号，并且由于所述第二同步信号的同步驱动控制，所述第二驱动集成电路3126同时对所述第二显示区3122输出相应数据信号，所述第三驱动集成电路3156同时对所述第三显示区3152输出相应数据信号，并且所述第一驱动集成电路3116和所述第三驱动集成电路3156中的至少一个同步地对显示区域输出相应扫描信号。另外，当所述第一折叠区311与所述第二折叠区312以第一折叠轴32为轴心折叠时（即处于折叠状态），此时所述第一显示区3112与所述第二显示区3122中的其中一个会发光显示，而另一个则为暗屏的状态，以下以所述第一显示区3112为暗屏的状态以及所述第二显示区3122与所述第三显示区3152发光显示为例（即同时所述第二折叠区312与所述第三折叠区315以第二折叠轴33为轴心展开），此时所述第一驱动集成电路3116不会对所述第一显示区3112输出相应数据信号，并且由于所述第二同步信号的同步驱动控制，所述第二驱动集成电路3126以及所述第三驱动集成电路3156会同时分别对所述第二显示区3122以及所述第三显示区3152输出相应数据信号，并且所述第一驱动集成电路3116和所述第三驱动集成电路3156中的至少一个同步地对显示区域输出相应扫描信号。在此例子中，所述第一驱动集成电路3116由于不需要对所述第一显示区3112输出相应数据信号而达到节省功耗的功效。进一步地，若此时的相应扫描信号为由所述第三驱动集成电路3156发送，则所述第一驱动集成电路3116可以停止驱动，而所述第一显示区3122则处于待机状态，此时当所述第一驱动集成电路3126接收到唤醒信号脉冲时（例如所述第一折叠区311与所述第二折叠区312再次以所述第一折叠轴32为轴心展开时），所述第一显示区3122会由待机状态转变为发光显示的正常工作模式。可以理解的是，所述第一显示区3112与所述第二显示区3122为发光显示以及所述第三显示区3152为暗屏状态的情况可以使用上述来作说明，在此不加以赘述。进一步地，当所述第一折叠区311、所述第二折叠区312、以及所述第三折叠区315均处于折叠状态时，所述第一显示区3112、所述第二显示区3122、以及所述第三显示区3152中的至少一个为暗屏的状态，此情况亦可以使用上述来作说明，在此不加以赘述，本领域技术人员可以根据需求对折叠状态时的显示区进行发光显示或是暗屏的配置，例如当所述第一折叠区311与所述第二折叠区312以第一折叠轴32为轴心折叠时，所述第一折叠区311为面朝上为发光显示，所述第二折叠区312为面朝下为暗屏的状态。
在本实施例中，所述第一驱动集成电路3116负责传送给所述第一显示区3112的相应数据信号，所述第二驱动集成电路3126负责传送给所述第二显示区3112的相应数据驱动信号，所述第三驱动集成电路3156负责传送给所述第三显示区3152的相应数据信号。可见，位于不同折叠区中的驱动集成电路可以独立对与其对应的显示区进行一对一的控制操作，即所述第一折叠区311中的所述第一驱动集成电路3116可以控制所述第一显示区3112的发光显示，所述第二折叠区312中的所述第二驱动集成电路3126可以控制所述第二显示区3122的发光显示，所述第三折叠区315中的所述第三驱动集成电路3156可以控制所述第三显示区3152的发光显示，从而达到节省功耗的效果。可以理解的是，此时用以发光显示的相应扫描信号会由所述第一驱动集成电路3116和所述第三驱动集成电路3156中的至少一个提供。本发明第二实施例的更多细节可以参照本发明的第一实施例，在此不加以赘述。
应当理解的是，本发明具有多种折叠的可能性，也就是说显示区的发光显示以及暗屏状态不限于上述的示例性说明，并且本说明书以两个折叠区以及三个折叠区作说明，不应解释为对本发明的限制，本发明可以包括至少三个以上的折叠区，在不脱离本发明的精神下，均为本发明的保护范围。
基于上述，本发明通过将驱动集成电路设置于不同的折叠区，并且和与其对应的显示区中的像素驱动电路单元通过相应数据线电连接，以提供所述显示区的相应数据信号，实现对显示区的一对一显示控制，并且当折叠显示面板中的至少一个显示区不需要发光显示时，对应其设置的驱动集成电路可以停止驱动，减少功耗的浪费。进一步地，本发明更可以应用于三个或三个以上显示区的显示面板。可见，本发明具有明显地进步性，优势十分明显。
虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本申请的范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
