然而，上述触摸控制的实现方式，需要在LED显示屏外侧增加用于实现触控识别的感应边框，在使用过程中感应边框四周的发射管和接收管容易损坏，导致触摸控制的稳定性较差。

具体实施方式
为了使本申请实施例的上述目的、特征和优点能够更加明显易懂，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其它实施例，均属于本申请保护的范围。
图1为现有技术中LED显示屏的结构示意图。如图1所示，目前，多数LED显示屏包括：LED灯板、控制单元和触控屏控制系统。其中，LED灯板包括：LED灯珠和驱动芯片。LED灯珠设置在LED灯板的表面，或者说，LED显示屏的表面。驱动芯片设置在LED灯板的背面。图1仅是示例性的给出了LED灯板上几个LED灯珠的位置。
触控屏控制系统包括：触控主控模块、驱动模块、感应模块，以及，安装在LED显示屏的前面外框内、且排布在屏幕四周的发射管和接收管。发射管和接收管相对设置，图1仅是示例性的给出了发射管和接收管在屏幕上的设置方式。
控制单元可以外接视频源，并将接收到的视频信号，经过内部算法转化成显示信号后发送给驱动芯片。显示信号分为数据信号和控制信号，数据信号即显示画面的信号，而控制信号则是控制LED驱动芯片的工作状态。
驱动芯片在接收到控制单元提供的数据信号和控制信号后，可以驱动所连接的LED灯珠发出对应的光，从而实现视频画面的显示。
触控主控模块控制驱动模块通过发射管定向发送红外线等不可见光波束(也可以称为触控驱动信号)，控制感应模块通过接收管检测发射管定向发送的不可见光波束，从而在LED显示屏的前面对应形成横竖交叉的波束矩阵。当定向波束被触控LED显示屏的触控 物阻挡，即可检测并定位触控物的触摸位置。
但是，上述实现触控的方式存在如下问题：
(1)需要在LED显示屏外侧增加用于实现触控识别的感应边框，在使用过程中感应边框四周的发射管和接收管容易损坏，导致触摸控制的稳定性较差。
由于对LED灯珠的触控识别和显示驱动是两个单独的系统，导致触摸控制的准确性较差、稳定性较差、硬件成本较高。
(3)对LED显示屏的屏幕形态有要求，无法适用于任一屏幕形态的LED显示屏。例如，当LED显示屏为弧形或异形屏时，这些定向波束无法形成排布在屏幕前方的矩阵，导致LED显示屏无法实现触控功能。
目前，虽然也有一些其他的控制方式，例如语音控制LED显示屏和/或遥控控制LED显示屏。但是这些控制方式易受到环境的干扰，控制的准确性和可靠性较差。
图2为一种LED灯珠的结构示意图，如图2所示，目前，一颗LED灯珠通常由红、绿、蓝(即R/G/B)三原色发光芯片组成全彩的像素点，从而实现画面的显示。即，一颗LED灯珠包括：用于显示红色R的发光芯片(简称R发光芯片)、用于显示绿色G的发光芯片(简称G发光芯片)、用于显示蓝色B的发光芯片(简称B发光芯片)。
另外，LED灯珠上设置有金属材质的支架1、支架2、支架3和支架4，用于引出所连接的发光芯片的电极，或者说，以使发光芯片通过对应的支架与相应的驱动芯片连接。
以图2为例，支架1用于将R发光芯片的负极与“用于驱动R发光芯片显示的驱动芯片”连接，支架2用于将G发光芯片的负极与“用于驱动G发光芯片显示的驱动芯片”连接，支架3用于将B发光芯片的负极与“用于驱动B发光芯片显示的驱动芯片”连接。
支架4用于将R发光芯片的正极、G发光芯片的正极、B发光芯片的正极与供电芯片连接，以为各发光芯片供电。或者，支架4用于将R发光芯片的正极、G发光芯片的正极、B发光芯片的正极与行驱动芯片连接，行驱动芯片与供电芯片连接，以使行驱动芯片向所连接的LED灯珠通过发送扫描信号(即行扫描信号)的方式实现间歇供电。
应理解，图2仅是一种示例，本申请并不对各支架在LED灯珠上的设置位置，以及，各发光芯片在LED灯珠上的设置位置进行限定。
发明人通过研究发现，LED显示屏表面的LED灯珠和用于驱动LED灯珠显示的驱动芯片之间的线路上存在电容(例如自电容或者互电容)。以图2为例，支架1与支架4之间、支架2与支架4之间、支架3与支架4之间均存在电容。此时，当有物体(例如手指等)靠近或者接触到LED显示屏的表面的LED灯珠时，LED灯珠和驱动芯片之间的电容的容值会发生变化。因此，可以通过驱动芯片来监控该电容的容值变化，从而实现触控功能。
有鉴于此，本申请提供一种LED显示装置、控制方法、芯片、介质及程序产品，LED显示装置的LED灯板上设置的第一驱动芯片具有显示驱动模式和触控驱动模式两种驱动模式，从而可以基于控制单元的控制信号从一种驱动模式切换至另一种驱动模式，以实现LED灯珠的显示驱动和触控识别。
由于对LED灯珠的触控识别和显示驱动均是通过LED灯板上设置的第一驱动芯片实现，无需在LED显示装置的外侧增加其它用于实现触控识别的附件，也无需专门设置触控识别的系统(例如，红外框触控组件和红外框触摸系统)，提高了触摸控制的准确性和稳 定性，降低了硬件成本，也不会受到LED显示装置自身屏幕形状的限制和外界环境的干扰，从而可以在LED显示装置的屏幕在任何形状时(例如弧形、异形或者采用拼接的方式构成)均能实现触摸控制。
下面结合具体的实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。
图3为本申请实施例提供的一种LED显示装置的结构示意图。如图3所示，LED显示装置10包括：LED灯板11和控制单元12，LED灯板11包括LED灯珠13和第一驱动芯片14，第一驱动芯片14分别与控制单元12和LED灯珠13连接。在一些实施例中，控制单元12也可以称为主控系统或者主控芯片等。
本实施例不限定上述第一驱动芯片14的个数和LED灯珠13的颗数，具体可以根据实际需求设置。例如，LED灯板11可以包括有多颗LED灯珠13。各LED灯珠13可以通过预设方式进行排列。在LED显示装置10中，通过控制不同位置的LED灯珠13的亮灭状态而对应显示不同的图像或字符。LED灯板11可以包括多个第一驱动芯片14。每个第一驱动芯片14用于驱动一颗或一组LED灯珠13等。
在本实施例中，第一驱动芯片14可以是连接LED灯珠13负极的驱动芯片。第一驱动芯片14不仅具有显示驱动模式，还具有触控驱动模式。当工作在显示驱动模式下时，第一驱动芯片14可以执行显示驱动操作，即，驱动LED灯珠13显示的操作。当工作在触控驱动模式时，第一驱动芯片14可以执行触控驱动操作，即，检测所连接的LED灯珠13是否被触控。也就是说，第一驱动芯片14可以通过检测LED灯珠13和该第一驱动芯片14之间的电容的容值是否发生变化，来判断LED灯珠13是否被触控。
因此，在本实施例中，控制单元12可以根据第一驱动芯片14的触控识别结果，控制第一驱动芯片14驱动所连接的LED灯珠13显示。
例如，在第一驱动芯片14的触控识别结果表征有至少一颗LED灯珠13被触控物触控时，可以控制第一驱动芯片14驱动所连接的LED灯珠13显示触控响应内容。此处所说的触控响应内容例如可以与用户当前触控所要实现的功能有关。以用户使用LED显示装置10进行书写操作为例，则此处所说的触控响应内容例如可以是用户通过触控功能所书写的内容。再例如，用户使用LED显示装置10进行切换视频操作为例，则此处所说的触控响应内容例如可以是播放下一视频，或者是，可供用户切换选择的各视频的介绍等。
应理解，关于控制单元12如何获取触控响应内容，以及，控制第一驱动芯片14驱动LED灯珠13显示触控响应内容，可以参见现有的实现方式，对此不再赘述。
需说明，在第一驱动芯片14的触控识别结果表征无LED灯珠13被触控物触控时，控制单元12可以控制第一驱动芯片14驱动所连接的LED灯珠13继续进行当前视频源的图像帧的显示。
本申请不限定上述第一驱动芯片14触发模式切换的实现方式。例如，第一驱动芯片14可以在控制单元12的控制下进行模式切换，也可以自主进行模式切换。
以第一驱动芯片14在控制单元12的控制下进行模式切换为例，示例性的，控制单元12，可以通过向第一驱动芯片14发送第一控制信号，控制第一驱动芯片14从显示驱动模式切换至触控驱动模式；和/或，通过向第一驱动芯片14发送第二控制信号，控制第一驱 动芯片14从触控驱动模式切换至显示驱动模式。通过上述方式，LED显示装置10可以通过LED灯板11上设置的第一驱动芯片14实现LED灯珠13的触控识别和显示驱动。
视频源是由多帧图像组成的，因此LED显示装置10在显示视频源的画面时，一般采用图像帧的方式进行显示，每一帧图像持续一定的时间。换帧显示时需要传输数据，因此，换帧之间存在数据传输的等待时间。该等待时间可以称为换帧间隙。即，从视频源的当前帧图像切换显示下一帧图像的间隙。
作为一种可能的实现方式，可以利用换帧间隙来实现触控识别。例如，控制单元12可以在换帧间隙内的第一时刻，向第一驱动芯片14发送第一控制信号，以控制第一驱动芯片14从显示驱动模式切换至触控驱动模式。在该实现方式下，第一驱动芯片14可以在换帧间隙内进行触控识别。
控制单元12可以在换帧间隙内的第二时刻，向第一驱动芯片14发送第二控制信号，以控制第一驱动芯片14从触控驱动模式切换至显示驱动模式。在该模式下，控制单元12可以采用如前述图1对应的实施例所描述的方式，将接收到的视频信号，经过内部算法转化成显示信号后发送给第一驱动芯片14。第一驱动芯片14在接收到控制单元12提供的显示信号后，可以驱动所连接的LED灯珠13发出对应的光，从而实现画面的显示。
其中，上述所说的第二时刻晚于第一时刻。例如，第一时刻可以是换帧间隙的开始时刻，第二时刻可以是换帧间隙的结束时刻，具体可以根据实际触控需求或者LED显示装置10的大小设置。
需说明，上述是以利用换帧间隙来实现触控识别进行的描述。具体实现时，也可以根据实际的触控需求，控制第一驱动芯片14的工作模式，例如，可以通过进一步压缩第一驱动系芯片驱动LED灯珠13的显示时间来进行触控识别，以提高触控识别的响应效率。
示例性的，以视频源一秒60帧画面，每个画面大约占用16.6毫秒为例，具体实现时，可以将16.6毫秒分为显示时间部分和触控识别时间部分(该触控识别时间部分可以是换帧间隙内的部分时长)，以使第一驱动芯片14可以实现LED灯珠13的触控识别和显示驱动。
以第一驱动芯片14自主进行模式切换为例，例如，第一驱动芯片14可以在驱动LED灯珠13完成视频源的当前帧图像显示后，从所述显示驱动模式切换至所述触控驱动模式，以及，在驱动LED灯珠13显示下一帧图像时，从所述触控驱动模式切换至所述显示驱动模式。
示例性的，第一驱动芯片14可以在驱动LED灯珠13完成视频源的当前帧图像显示后的第三时刻，从所述显示驱动模式切换至所述触控驱动模式，以及，在驱动LED灯珠13显示下一帧图像之前的第四时刻，从所述触控驱动模式切换至所述显示驱动模式，该第四时刻晚于第三时刻。
再例如，第一驱动芯片14可以周期性的在两个模式之间进行切换。例如，在第一个周期从显示驱动模式切换至触控驱动模式，对所连接的LED灯珠13进行触控识别，在第二个周期从触控驱动模式切换至显示驱动模式，以驱动所连接的LED灯珠13显示，在第三个周期再从显示驱动模式切换至触控驱动模式，以此类推。
具体实现时，第一驱动芯片14自主进行模式切换例如可以通过其内置的计时器实现切换时间点的控制。
需说明，在第一驱动芯片14自主进行模式切换的实现方式下，第一驱动芯片14可以 将其当前所处于的模式同步给控制单元12，以使控制单元12可以基于第一驱动芯片14所处的模式进行相应操作。例如，在显示驱动模式下，控制单元12可以向第一驱动芯片14发送显示信号。在触控驱动模式下，控制单元12可以根据所述第一驱动芯片14的触控识别结果，控制所述第一驱动芯片14驱动所连接的LED灯珠13显示。
本申请提供的LED显示装置10，其LED灯板11上设置的第一驱动芯片14具有显示驱动模式和触控驱动模式两种驱动模式，可以基于控制单元12的控制信号从一种驱动模式切换至另一种驱动模式，以实现LED灯珠13的显示驱动和触控识别。
(1)由于对LED灯珠的触控识别和显示驱动均是通过LED灯板上原本设置的第一驱动芯片实现，无需在LED显示装置的外侧增加其它用于实现触控识别的附件，也无需专门设置触控识别的系统(例如，红外框触控组件和红外框触摸系统)，提高了触摸控制的准确性和稳定性，也不会受到LED显示装置自身屏幕形状的限制，从而可以在LED显示装置的屏幕为弧形、异形或者采用拼接的方式构成时实现触摸控制。
(2)相较于其他控制方式(例如语音控制和/或遥控控制)，本申请的LED显示装置在实现控制时，不易受到环境或噪音的干扰，控制的准确性和可靠性更高。
(3)相较于在LED显示装置的外侧增加其它用于实现触控识别的附件，或其他控制方式(例如语音控制和/或遥控控制)，本申请的LED显示装置在实现控制时，无需额外配备相应的硬件以及系统，降低了LED显示装置的硬件成本。
应理解，上述图3仅是示例性的给出了LED显示装置10中与本申请相关的组件和部件，具体实现时，LED显示装置10还可以包括其他的部件或组件，例如，连接LED灯珠13正极的供电芯片等，本申请对此不进行限定。
下面对第一驱动芯片14工作在触控驱动模式下时，具体如何实现触控识别的进行说明：
如前所述，LED灯珠13和第一驱动芯片14之间的线路上存在电容(例如自电容或者互电容)。当有物体(例如手指等)靠近或者接触到LED灯珠13时，LED灯珠13和第一驱动芯片14之间的电容的容值会发生变化。
因此，第一驱动芯片14可以向所连接的各LED灯珠13发送触控驱动信号。然后，第一驱动芯片14可以检测各LED灯珠13基于触控驱动信号返回的触控感应信号，来识别是否有触控物触控所连接的LED灯珠13。
以图2的支架1和支架4之间的电容为例，例如，第一驱动芯片14向LED灯珠13的支架1发送触控驱动信号，并检测支架1返回的触控感应信号。由于支架4会收到行扫描驱动芯片或供电芯片发送的供电信号，使得支架1与支架4之间存在电容。当有触控物(例如触控笔或用户的手指等)触控该LED灯珠13时，支架1和支架4之间的容值会发生变化，使得触控驱动信号中的部分信号会被触控物耦合衰减，导致第一驱动芯片14感应到的触控感应信号的参数会发生变化(例如，触控感应信号的信号强度和/或触控感应信号的电流大小不同)。因此，可以通过各LED灯珠13返回的触控感应信号，判断出该LED灯珠13是否有触控物触控。
应理解，此处所说的信号强度例如可以是信号的幅值，该幅值可以是任一随电容容值变化而变化的特征，例如，电压幅值。
图4为本申请实施例提供的一种信号强度示意图，如图4所示，示例性的，以第一驱 动芯片14发出如图4所示的触控驱动信号为例，则在该示例下，当无任何触控物触控LED显示装置10时，第一驱动芯片14感应到的触控感应信号强度为H。当有触控物触控其所连接的LED灯珠13时，受电容容值变化的影响，触控之前电容的介质为空气和灯珠本体的封装材料，触控时电容的介质在上述空气和灯珠本体的封装材料的基础上增加了触摸物，因此电容容值会发生变化(增大)，触控感应信号的强度会发生变化(减弱)，导致第一驱动芯片14感应到的触控感应信号强度例如为小于H的H1，从而可以基于触控感应信号确定有触控物触控该LED灯珠13。
一种可能的实现方式，第一驱动芯片14连接一颗LED灯珠13，在该实现方式下，第一驱动芯片14可以向该LED灯珠13发送触控驱动信号，供电芯片向LED灯珠13发送供电信号，从而使得第一驱动芯片14可以基于该LED灯珠13返回的触控感应信号，判断该LED灯珠13是否有触控物触控。
另一种可能的实现方式，图5为本申请实施例提供的另一种LED显示装置的结构示意图。如图5所示，LED灯板11有多颗LED灯珠13。多颗LED灯珠13可以采用X行、Y列的行列排布方式。其中，X和Y均为大于或等于1的整数。应理解，此处所说的行和列是相对垂直的关系。本申请并不限定行和列在LED灯板11上的相对位置关系。例如，此处所说的行可以是在LED灯板11上横向排布的一行，在该实现方式下，列可以是LED灯板11上纵向排布的一列。或者说，行可以是在LED灯板11上纵向排布的一行，在该实现方式下，列可以是LED灯板11上横向排布的一列。图5是以X和Y均等于5，行是在LED灯板11上纵向排布的一行，列是LED灯板11上横向排布的一列为例的示意图。
在该实现方式下，LED灯板11还可以包括：一个或多个行驱动芯片15；每个行驱动芯片15与多组LED灯珠13连接，该组LED灯珠13可以是沿行向排布的一列灯珠，用于逐行向所连接的LED灯珠13发送扫描信号(即行扫描信号)。第一驱动芯片14可以连接一组LED灯珠13，该组LED灯珠13可以是沿列向排布的一列灯珠。即，第一驱动芯片14与一组列向排布的LED灯珠13连接。
第一驱动芯片14可以向该组LED灯珠13发送触控驱动信号(可以视为列驱动信号)，并检测该组LED灯珠13中的各LED灯珠13基于触控驱动信号和扫描信号返回的触控感应信号。
继续参照图5，以第一驱动芯片14连接的是D5列的一组LED灯珠13，行驱动芯片15连接的是S1行、S2行、S3行、S4行、S5行的5组LED灯珠13为例，则第一驱动芯片14可以向该组LED灯珠13发送触控驱动信号。另外，行驱动芯片15在逐行扫描时，即，依次向S1行、S2行、S3行、S4行、S5行的LED灯珠13发送扫描信号(也可以称为供电信号)时，即每次向一行的LED灯珠13发送扫描信号时，D5列的LED灯珠13会依次收到扫描信号，从而会依次基于扫描信号和触控驱动信号得到触控感应信号，并反馈给第一驱动芯片14，从而使第一驱动芯片14可以得到每个D5列每颗LED灯珠13反馈的触控感应信号。
应理解，上述仅是示例性的给出了一些可能的第一驱动芯片14与LED灯珠13的连接方式，以及，在该连接下第一驱动芯片14如何获取各LED灯珠13返回的触控感应信号。具体实现时，可以根据第一驱动芯片14与LED灯珠13的实际连接方式，适应性调整获取各LED灯珠13返回的触控感应信号的方式，对此不进行限定。
第一驱动芯片14在获取到各LED灯珠13返回的触控感应信号之后，可以采用如下两种方式向控制单元12进行触控识别反馈：
第一种实现方式：第一驱动芯片14根据各LED灯珠13的触控感应信号，自行判断是否有至少一颗LED灯珠13被触控物触控。在检测到有至少一颗LED灯珠13被触控物触控时，向控制单元12发送用于表征触控识别结果的触控信息。该触控信息包括：触控物的位置信息和/或至少一颗LED灯珠13的标识。上述所说的触控物的位置信息例如可以是触控物在LED灯板11上的坐标位置。上述所说的LED灯珠13的标识能够唯一反应该LED灯珠13在LED灯板11上的位置，进而能够表征触控物的位置。
也就是说，在本实现方式下，第一驱动芯片14仅在有触控物触控时向控制单元12反馈。当无LED灯珠13被触控物触控时，第一驱动芯片14无需与控制单元12交互，从而减少了第一驱动芯片14与控制单元12之间的数据传输量，降低了功耗。
示例性的，第一驱动芯片14例如可以预先存储有无触控物触控时返回的触控感应信号的参数(例如，触控感应信号的信号强度和/或触控感应信号的电流大小不同)。因此，第一驱动芯片14可以根据各LED灯珠13的触控感应信号的参数，以及，预先存储的各LED灯珠13无触控时的触控感应信号的参数，确定各LED灯珠13是否有触控物触控。
假定第一驱动芯片14连接了3颗LED灯珠13，其中，第1颗LED灯珠13被触控物触控，则第一驱动芯片14可以向控制单元12发送触控信息。该触控信息包括：触控物的位置信息和/或该第1颗LED灯珠13的标识。
在该实现方式下，控制单元12可以在通过前述所说的控制信号，控制第一驱动芯片14从触控驱动模式切换至显示驱动模式后，根据触控信息，控制第一驱动芯片14驱动至少一颗LED灯珠13显示触控响应内容。
此处所说的触控响应内容例如可以与用户当前触控所要实现的功能有关。例如，以用户使用LED显示装置10进行书写操作为例，则此处所说的触控响应内容例如可以是用户通过触控功能所书写的内容。再例如，用户使用LED显示装置10进行切换视频操作为例，则此处所说的触控响应内容例如可以是播放下一视频，或者是，可供用户切换选择的各视频的介绍等。
应理解，关于控制单元12如何获取触控响应内容，以及，控制第一驱动芯片14驱动至少一颗LED灯珠13显示触控响应内容，可以参见现有的实现方式，对此不再赘述。
第二种实现方式：第一驱动芯片14根据各LED灯珠13的触控感应信号，生成用于全量反馈各LED灯珠13是否被触控物触控的触控信号，并向控制单元12发送用于表征触控识别结果的触控信号。由控制单元12基于触控信号自行判断是否有至少一颗LED灯珠13被触控物触控。也就是说，在本实现方式下，第一驱动芯片14会全量反馈各LED灯珠13的触控情况。
示例性的，第一驱动芯片14例如可以预先存储有无触控物触控时返回的触控感应信号的参数(例如，触控感应信号的信号强度和/或触控感应信号的电流大小不同)。因此，第一驱动芯片14可以根据各LED灯珠13的触控感应信号的参数，以及，预先存储的各LED灯珠13无触控时的触控感应信号的参数，确定各LED灯珠13是否有触控物触控。
然后，第一驱动芯片14可以根据各LED灯珠13是否有触控物触控，生成触控信号。其中，触控信号中被触控物触控的LED灯珠13对应的字段为第一值，未被触控物触控的 LED灯珠13对应的字段为第二值。应理解，上述触控信号中，各LED灯珠13对应的字段可以按照预设顺序排列，从而可以基于触控信号在确定有LED灯珠13被触控物触控时，可以基于该值出现的位置，确定被触控物触控的LED灯珠13的位置。
或者，触控信号中被触控物触控的位置回传高电平的信号，未被触控物触控的位置回传低电平的信号。应理解，上述触控信号中，各LED灯珠13对应的电平可以按照预设顺序排列，从而可以基于触控信号在确定有LED灯珠13被触控物触控时，可以基于该高电平出现的位置，确定被触控物触控的LED灯珠13的位置。另外，此处所说的高电平和低电平为相对概念。例如，高电平为5V，低电平为0.5V等。
以触控信号中被触控物触控的LED灯珠13对应的字段为第一值，未被触控物触控的LED灯珠13对应的字段为第二值为例，其中，第一值为1，第二值为0。假定第一驱动芯片14连接了3颗LED灯珠13，第一颗LED灯珠13被触控物触控，则触控信号可以是100，或者是，包括一个高电平，2个低电平的脉冲信号等。
在该实现方式下，控制单元12可以根据触控信号，检测是否有LED灯珠13被触控物触控。例如，控制单元12可以根据触控信号中是否存在第一值，确定是否有LED灯珠13被触控物触控，或者，控制单元12可以根据触控信号中是否存在高电平，确定是否有LED灯珠13被触控物触控，以及，被触控物触控的LED灯珠13的位置。
然后，在根据触控信号，检测到有至少一颗LED灯珠13被触控物触控时，控制单元12可以在通过前述所说的控制信号，控制第一驱动芯片14从触控驱动模式切换至显示驱动模式后，控制第一驱动芯片14驱动至少一颗LED灯珠13显示触控响应内容。应理解，关于控制单元12如何获取触控响应内容，以及，控制第一驱动芯片14驱动至少一颗LED灯珠13显示触控响应内容，可以参见第一种实现方式的描述，对此不再赘述。
通过上述方式，第一驱动芯片14可以通过检测所连接的LED灯珠13与第一驱动芯片14之间的线路上的电容的容值是否发生变化，实现触控功能。
如前所述，LED显示装置10的LED灯板11上可以设置有一个或多个第一驱动芯片14，每个第一驱动芯片14用于连接LED灯板11上的部分LED灯珠13，以对所连接的LED灯珠13进行驱动控制。
下面以LED灯板11包括N个的第一驱动芯片14为例，描述N个第一驱动芯片14与控制单元12和LED灯珠13之间的连接方式。其中，N为大于或等于2的整数。
图6为本申请实施例提供的再一种LED显示装置的结构示意图。如图6所示：
每个第一驱动芯片14均包括：数据输入端(DATA IN)、数据输出端(DATA OUT)，以及，输出端(OUT)，控制单元12包括：输入端和输出端。各第一驱动芯片14的每个输出端与一颗或一组LED灯珠13连接。

第i级的第一驱动芯片14的数据输出端与第i+1级的第一驱动芯片14的数据输入端连接，用于在显示驱动模式下，向第i+1级第一驱动芯片14传输显示信号，在触控驱动模式下，向第i+1级第一驱动芯片14传输第1级至第i级的第一驱动芯片14生成的触控识别反馈，1≤i＜N。触控识别反馈包括：触控信息或触控信号。
第N级的第一驱动芯片14的数据输出端与控制单元12的输入端连接，用于在触控驱动模式下，向控制单元12传输第1级至第N级的第一驱动芯片14生成的触控信号。
如前所述，LED灯珠13通常由红、绿、蓝(即R/G/B)三原色发光芯片组成全彩的像素点，从而实现画面的显示。即，一颗LED灯珠13包括：三原色中的第一颜色发光芯片、三原色中的第二颜色发光芯片和三原色中的第三颜色发光芯片。
可选地，在该实现方式下表，所述第一驱动芯片的每个输出端与一颗或一组LED灯珠13的第一颜色发光芯片连接。此处所说的第一颜色例如可以是三原色中的红色或蓝色或绿色。
在该实现方式下，LED灯板11还包括N个级联的第二驱动芯片和N个级联的第三驱动芯片；每个第二驱动芯片和每个第三驱动芯片均包括：数据输入端、数据输出端，以及，输出端；
第二驱动芯片的每个输出端与一颗或一组LED灯珠13的第二颜色发光芯片连接，用于驱动LED灯珠13显示三原色中的第二颜色。

第一级的第二驱动芯片的数据输入端和第一级的第三驱动芯片的数据输入端均与控制单元12的输出端连接，用于接收控制单元12传输的显示信号；
第i级的第二驱动芯片的数据输出端与第i+1级的第二驱动芯片的数据输入端连接，用于在显示驱动模式下，向第i+1级第二驱动芯片传输显示信号，1≤i＜N；
第i级的第三驱动芯片的数据输出端与第i+1级的第三驱动芯片的数据输入端连接，用于在显示驱动模式下，向第i+1级第三驱动芯片传输显示信号，1≤i＜N。
在该实现方式下，仅用于驱动LED灯珠13的第一颜色发光芯片的第一驱动芯片14同时具有显示驱动模式和触控驱动模式，以实现LED灯珠13的显示驱动和触控识别。对于驱动LED灯珠13的第二颜色发光芯片的第二驱动芯片和驱动LED灯珠13的第三颜色发光芯片的第三驱动芯片可以仅保留其显示驱动模式，无需实现触控驱动。
应理解，在该实现方式下，第一驱动芯片14、第二驱动芯片和第三驱动芯片可采用具有相同电路结构的芯片，也可以采用不同电路结构的芯片。例如，第一驱动芯片14可以包括：具有显示驱动模式和触控驱动模式的电路结构。第二驱动芯片和第三驱动芯片可以包括仅具有显示驱动模式的电路结构，也可以采用第一驱动芯片14相同的电路结构，但不使用触控驱动模式。
可选地，在第一驱动芯片14、第二驱动芯片和第三驱动芯片均支持显示驱动模式和触控驱动模式时，可以采用第一驱动芯片14实现触控驱动，也可以同时使用至少两个驱动芯片实现触控驱动等，本申请对此不进行限定。
下面以第一驱动芯片14向控制单元12反馈触摸信号为例，给出一种可能的第一驱动芯片14的结构示意图。
图7为本申请实施例提供的一种第一驱动芯片14的外围管脚示意图。如图7所示，第一驱动芯片14的外围管脚包括DATA IN管脚、DATA OUT管脚、OUT管脚、R-XT管脚、GND管脚和VCC管脚等。
其中，DATA IN管脚，用于输入控制单元12所传输过来的显示信号，或者级联的其 它第一驱动芯片14所传输过来的触摸信号。
DATA OUT管脚，用于向下一级第一驱动芯片14传输显示信号，或者，传输第1级至第i级的第一驱动芯片14生成的触控识别反馈，1≤i＜N。

R-XT管脚控制信号输出端的输出电阻。
VCC管脚和GND管脚则分别连接电源和接地，从而为第一驱动芯片14进行供电。
此外，第一驱动芯片14还可以包括其它外围管脚，用于接收各种控制信号，各种控制信号可以控制第一驱动芯片14实现不同的功能。例如，第一驱动芯片14可以包括：CLK管脚、GCLK管脚、LE管脚。其中，CLK管脚和GCLK管脚分别用于传输时钟信号及控制时钟信号，LE管脚则传输使能信号，控制显示信号在第一驱动芯片14内部的存储或输出功能是否执行。
应理解，当LED显示装置10包括N个级联的第一驱动芯片14时，各第一驱动芯片14的用于接收各种控制信号的外围管脚均与控制单元12连接，以由控制单元12传输相应控制信号至各第一驱动芯片14，例如图6所示的连接方式。
图8为本申请实施例提供的一种第一驱动芯片14内部架构的示意图。如图8所示：
第一驱动芯片14包含控制器，用于实现第一驱动芯片14的功能的控制。例如，控制器接收控制单元12发送的控制信号(Signal)，发出各种控制指令控制芯片内部各个部分。Signal例如可以是CLK信号、GCLK信号、LE信号等中一个或多个。移位寄存器的作用是寄存传输数据。当接收到来自控制单元12的数据信号时，在CLK信号的配合下，数据信号进行移位寄存或者传输。应理解，显示信号或者触控信号都可以通过移位寄存器寄存并传输。
SARM1用于存储显示相关的寄存器指令，PWM驱动器是打开显示信号对应的OUT管脚，配合起来调节驱动LED显示。
SARM2用于存储所连接的LED灯珠13无触控物触控时的触控感应信号的参数，数值比较器的作用是将经滤波放大处理后的各LED灯珠13反馈的触控感应信号的参数和无触控物触控时的触控感应信号的参数进行比较，得到触控信号。然后，再将触控信号传输到移位寄存器。

(1)由于对LED灯珠的触控识别和显示驱动均是通过LED灯板上原本设置的第一驱动芯片实现，无需在LED显示装置的外侧增加其它用于实现触控识别的附件，也无需专门设置触控识别的系统，避免了外加触控边框使用过程中感应边框四周的发射管和接收管容易损坏，导致的触摸控制的稳定性较差的问题，提高了触摸控制的准确性和稳定性。同时，由于无需在LED显示装置的外侧增加其它用于实现触控识别的附件，不会受到LED显示装置自身屏幕形状的限制，从而可以在任意屏幕形态的LED显示装置(例如屏幕为弧形、 异形、平面形或者采用拼接的方式构成时)实现触摸控制。
(2)相较于其他控制方式(例如语音控制和/或遥控控制)，本申请的LED显示装置在实现控制时，不易受到环境或噪音的干扰，控制的准确性和可靠性更高。
(3)相较于在LED显示装置的外侧增加其它用于实现触控识别的附件，或其他控制方式(例如语音控制和/或遥控控制)，本申请的LED显示装置在实现控制时，无需额外配备相应的硬件以及系统，降低了LED显示装置的硬件成本。
