具体实施方式
为使本申请实施例的申请构思的目的、技术方案和优点更加清楚，下面将 结合附图和一些实施例对所述申请构思做详细描述。
一个或多个实施例中，如图1所示，为触控显示设备和终端设备之间构成的系统示意图。如图1所示，该系统可以包括：终端设备01和触控显示设备02，该触控显示设备02可以具有触控区域以供用户进行触控。
参考图1，该终端设备01和触控显示设备02之间可以通过有线或无线网络建立有通信连接，且终端设备01与触控显示设备02可以基于该通信连接进行数据传输。如，触控显示设备02可以获取基于用户对触控显示设备02的触控区域的触控操作生成的触控数据，并将该触控数据实时发送至终端设备01，以供终端设备01显示。即触控显示设备02和终端设备01上显示的图像可以同步更新。可选的，触控显示设备02获取到的触控数据可以为直接基于用户在触控区域执行的触控操作生成的数据，或者，也可以为对用户在触控区域执行的触控操作进行一系列处理(如，优化)后生成的数据。
可选的，一个或多个实施例中，结合图1和图2，该触控显示设备02至少可以包括数据缓存器(buffer)021、显示数据随机存储器(display data random access memory，DDRAM)022以及系统芯片(system on chip，SOC)023，该系统芯片023也可以称为处理芯片。该处理芯片可以包括能够实现本公开实施例记载的触控显示设备的触控响应装置。其中，该数据缓存器021和DDRAM 022均可以用于缓存非压缩视频传送流(transport stream，TS)数据。即DDRAM 022也是缓存器的一种，只是一般进行帧缓存(即，帧存)，DDRAM 022缓存的每帧数据均可以构成一帧图像。
可选的，触控显示设备02可以为集触控、显示以及能够与终端设备01进行数据传输为触控一体机。从应用场景角度，触控一体机为包含书写、文件播放和视频等功能的智能交互设备，比如会议机、教育机等。例如，图1示出的触控显示设备02为教育或会议等场景下的IWB。终端设备01可以为开放式可拔插规范(open pluggable specification，OPS)的内置计算机设备或外置计算机设备。也即是，触控显示设备02可以内置一OPS终端设备，或，触控显示设备02与独立于触控显示设备02的一计算机设备建立连接。且，触控显示设备02可以为能够支持多处理系统的显示设备。例如，图1示出的终端设备01为外接笔记本电脑。
以触控显示设备为IWB为例对影响触控速度的因素进行以下分析：
IWB一般还可以包括基于触控操作进行触控驱动的触控驱动电路(touch drive integrated circuit，touch drive IC)，以及基于触控操作显示图像的显示驱动IC，也可以称为显示系统。影响IWB触控响应速度的因素可以包括如下几个方面：第一，触控驱动电路的触控坐标报点速率的影响；第二，IWB中配置的一些软件(如书写轨迹处理相关软件)算法的影响。如，数据包的传输、会话、表达和基于触控操作进行的图形拟合等软件算法；第三，显示系统对触控数据处理时产生的延时影响。如，显示系统对触控数据的处理可以包括：降噪、运动补偿、小角度计算、帧频变换和缩放等一系列处理。且显示系统一般是针对多帧数据进行同时处理。如，显示系统同时接收多帧触控数据，并对该多帧触控数据进行降噪或运动补偿。
随着触控驱动电路的迭代更新和软件算法的不断改善，显示系统的多帧处理成为造成触控延时感提升的主要因素。在进行多帧处理时，一般必然需要通过DDRAM 022进行缓存。假设同时进行三帧处理，且假设一帧(如，60赫兹Hz)处理带来x毫秒(ms)的延时，则同时进行三帧处理即可能带来3x ms的延时，进而造成触控延时感较为明显的现象。
例如，结合图3，假设用户在IWB上执行的触控操作为从a点至b点进行直线图像绘制，当用户在结束触控操作的同时，因触控延时问题，IWB上仅显示出a点至c点的直线图像，而并未显示出c点至b点的直线图像(图3以虚线标识未显示)，c点位于a点至b点之间。
本公开实施例提供了一种触控显示设备的触控响应方法，该方法通过关闭多帧处理相关算法，采用单帧先进先出(first input first output，FIFO)或行缓存(line buffer)模式对触控数据进行缓存，并基于点对点pixel by pixel全帧频/半帧频格式对触控数据进行帧频转换处理。在不降低触控显示设备显示的画面品质的前提下，有效减少触控延时，改善了用户体验。
图4是本公开一个或多个实施例提供的一种触控显示设备的触控响应方法流程图，该方法可以应用于图1所示的触控显示设备02的SOC中，或者说，该方法可以由触控显示设备02的SOC执行，在触控显示设备02的场景中实现。如图4所示，该方法可以包括：
步骤401、获取基于用户对触控显示设备的触控操作生成的触控数据。
当用户在触控显示设备的触控区域上进行触控操作时，触控显示设备的 SOC可以检测到该触控操作，并进一步获取基于该触控操作生成的触控数据。
步骤402、控制数据缓存器按照目标模式缓存该触控数据。
其中，该目标模式可以包括：单帧FIFO模式或行缓存模式。为了在保证可靠显示的同时，改善触控延时感，SOC可以通过控制数据缓存器按照上述目标模式对触控数据进行缓存，以减少帧存相关算法。
步骤403、基于目标帧频处理格式，对数据缓存器中的触控数据进行帧频转换处理。
在缓存触控数据后，SOC可以进一步基于目标帧频处理格式对数据缓存器中缓存的触控数据进行帧频转换处理，保证触控显示设备的可靠显示。可选的，该目标帧频处理格式可以为SOC预先从终端设备获取到的。
综上，本公开实施例提供了一种触控显示设备的触控响应方法。由于该方法可以获取基于用户对触控显示设备的触控操作生成的触控数据，可以控制数据缓存器按照单帧先进先出模式或行缓存模式缓存该触控数据，且可以基于目标帧频处理格式对数据缓存器中缓存的该触控数据进行帧频转换处理，因此在确保触控显示设备基于触控数据可靠显示的同时，通过减少帧存相关算法的方式提高触控响应速度，改善触控延时感。
以触控显示设备为IWB为例，对触控响应方法进行介绍：图5是本公开一个或多个实施例提供的另一种触控显示设备的触控响应方法流程图，可以应用于图1所示的触控显示设备02包括的SOC中。如图5所示，该方法可以包括：
步骤501、获取基于用户对所述触控显示设备的触控操作生成的触控数据。
可选的，SOC可以实时或每隔预设时间段检测用户是否在其触控区域进行了触控操作，若检测到触控操作后，SOC可以进一步获取基于该触控操作生成的触控数据。且，SOC获取到的触控数据可以为基于用户的触控操作直接生成，且未经过任何处理(如，运动补偿、降噪或美化等)的数据。或者，SOC获取到的触控数据可以为对用户的触控操作生成的触控数据进行上述优化处理后得到的数据。本公开实施例对获取到的触控数据不做限定。
另，结合图1实施例，由于触控显示设备可以内置一终端设备，或，外接一终端设备。且对于内置终端设备而言，触控操作可以通过内部触控跟随通道反馈至SOC，故，若触控显示设备是内置终端设备，则触控显示设备的SOC可 以在判定有内部触控跟随通道时，确定检测到触控操作。同理，对于外接终端设备而言，触控操作可以通过外部触控跟随通道反馈至SOC，故，若触控显示设备是外接终端设备，则触控显示设备的SOC可以在判定有内部触控跟随通道时，确定检测到触控操作。即“检测触控操作，获取触控数据”可以理解为“执行读取触控数据，判定通道是否为触控跟随”的操作。
步骤502、向终端设备发送格式获取请求。
可选的，由于触控显示设备在正常工作时，不仅可以基于接收到的触控操作显示图像，例如可以显示该触控操作的轨迹。或者，也可以不基于触控操作自动显示图像，如直接接收终端设备发送的图像并显示。对于未接收到触控操作正常显示的场景，因用户并未在触控显示设备上执行触控操作，故也不存在触控延时问题，而只有在基于触控操作显示图像的场景下才存在触控延时的问题，故，触控显示设备的SOC可以在检测到触控操作时，再进一步向其所连接的终端设备发送格式获取请求。相应的，若未检测到触控操作，即未获取到触控数据，则触控显示设备可以不执行下述步骤，如可以直接进入正常显示程序。
其中，SOC可以通过直接数字控制(direct digital control，DDC)通讯接口向终端设备发送格式获取请求。该格式获取请求可以用于请求最终基于触控数据进行显示时，对触控数据进行帧频处理的格式。如，该格式获取请求中可以携带有第一帧频处理格式和第二帧频处理格式。另，帧频(frame rate)是指每秒钟可以显示的帧或图像的数量，相应的，帧频处理可以是指控制触控显示设备同时显示几个帧频的触控数据对应图像。
为了进一步确保能够获取到需要的帧频处理格式，SOC向终端设备发送的格式获取请求中还可以携带有该两个帧频处理格式的请求优先级，请求优先级越大表明触控显示设备更想获取对应的帧频处理格式。如，该第一帧频处理格式的请求优先级可以大于第二帧频处理格式的请求优先级。
可选的，优先级较大的第一帧频处理格式可以为全帧频处理格式。优先级较小的第二帧频处理格式可以为半帧频处理格式。全帧频处理是指：同时处理的帧频数量与接收到的帧频数量相同。半帧频处理是指：同时处理的帧频数量为接收到的帧频数量一半，即所有帧频数量需经两次处理才能完成。
步骤503、接收终端设备响应于格式获取请求后返回的目标帧频处理格式。
可选的，由于触控显示设备进行触控数据处理时采用的帧频处理格式需要 与连接的终端设备所支持的帧频处理格式相同，且由于终端设备接收到的格式获取请求中携带的内容为第一帧频处理格式和第二帧频处理格式，因此终端设备发送至SOC的目标帧频处理格式要么为第一帧频处理格式，要么为第二帧频处理格式。即终端设备返回的目标帧频处理格式可以是终端设备支持的第一帧频处理格式或第二帧频处理格式。
另，若终端设备接收到的格式获取请求中还携带第一帧频处理格式的优先级大于第一帧频处理格式的优先级，则终端设备在接收到格式获取请求时，可以先确定自己所能支持的帧频处理格式，然后基于所能支持的帧频处理格式，以及接收到的格式获取请求中携带的优先级向SOC可靠发送目标帧频处理格式。如，若终端设备支持的帧频处理格式包含第一帧频处理格式和第二帧频处理格式，即终端设备能够支持优先需求的帧频处理格式，则终端设备当然尽可能向触控显示设备发送优先需求对应的第一帧频处理格式。即，SOC接收到的目标帧频处理格式为第一帧频处理格式。若终端设备支持的帧频处理格式包含第一帧频处理格式和第二帧频处理格式中的第二帧频处理格式，即终端设备不能够支持优先需求，则此时终端设备可以向SOC发送次优先需求对应的第二帧频处理格式。即，SOC接收到的目标帧频处理格式为第二帧频处理格式。
可选的，SOC在接收到目标帧频处理格式后，可以将目标帧频处理格式配置给自身，以供后续对触控操作的触控数据进行帧频处理，保证可靠显示。另，SOC还可以设置帧频为显示屏帧频模式，即帧频处理最终是用于显示图像。
步骤504、关闭DDRAM的配置功能。
结合上述图1实施例，DDRAM一般用于进行帧存，故为了减少帧存相关算法，SOC可以先关闭DDRAM的配置功能。
可选的，DDRAM可以包括各种不同功能的引脚，如，多个存储地址选择引脚A0-An、数据写入引脚data和读(read)写(write)选择引脚R/W。相应的，关闭DDRAM的配置功能可以通过下述方式中的至少一种方式实现：
第一，禁止DDR时钟信号(即，DDR CLK)输入至DDRAM。
第二，设置多个存储地址选择引脚(即，A0-An)为高阻态。
第三，设置数据写入引脚(即，data)为高阻态。
第四，设置读写选择引脚(即，R/W)为高阻态。
其中，高阻态是指一种输出状态，设置引脚为高阻态可以理解为设置引脚 悬空。相应的，通过设置引脚为高阻态，即可以实现对该引脚输出的信号的关断，即被设置高阻态的引脚不会输出信号至其他器件以对其他器件产生影响。当然，关闭DDRAM的配置功能也不限于上述几种实现方式。
若SOC在关闭DDRAM配置功能后，检测到触控显示设备某刻显示了非触控操作生成的图像(即进入正常显示状态)，即检测到从触控跟随通道切换至其他通道时，可以再次开启DDRAM的配置功能以保证IWB的正常运行。
步骤505、控制数据缓存器按照目标模式缓存触控数据。
其中，该该目标模式可以为单帧FIFO模式或行缓存模式。其中，单帧FIFO模式是指：每次仅处理一帧触控数据，且通过该数据缓存器写入读取触控数据时，先进入数据缓存器的触控数据先从数据缓存器中读出，即数据缓存器无需连接外部读写地址线。行缓存模式是指：通过数据缓存器写入读取触控数据时，当检测到执行换行操作时，读取一次触控数据。
在本公开实施例中，SOC可以在关闭DDRAM的配置功能之后，调整数据缓存器的工作模式为目标模式，即控制数据缓存器按照目标模式缓存获取到的触控数据。也即是，上述步骤504关闭DDRAM配置功能属于控制数据缓存器工作模式为上述目标模式的前提条件。
通过关闭DDRAM的配置功能，以及调整数据缓存器按照单帧FIFO模式或行缓存模式缓存触控数据，可以达到减少帧存算法的目的，进而提高了触控响应速度，改善了触控延时。可选的，单帧FIFO模式和行缓存模式可以均为点对点(即pixel by pixel)模式，保证显示数据和触控数据一一对应。SOC在配置帧频时，可以同时设置pixel by pixel处理模式。配置帧频和设置pixel by pixel处理模式也可以称为设置通道源输出操作。
步骤506、基于目标帧频处理格式对数据缓存器中的触控数据进行帧频转换处理。
SOC在缓存触控数据后，可以基于预先获取到的目标帧频处理格式，对缓存于数据缓存器中的触控数据进行帧频转换处理。可选的，SOC可以先判断目标帧频处理格式是否为优先需求的处理格式，并基于判断结果对触控数据进行帧频转换。
例如，假设请求优先级较高的帧频处理格式为第一帧频处理格式，第一帧频处理格式为全帧频处理格式，请求优先级较低的帧频处理格式为第二帧频处 理格式，第二帧频处理格式为半帧频处理格式。则当SOC获取到目标帧频处理格式后可以先判断是否为全帧频处理格式，若为全帧频处理格式，则此时SOC可以响应于目标帧频处理格式为第一帧频处理格式，通过对控制数据缓存器中的触控数据的行时钟信号和帧时钟信号进行信号锁定，从而实现对数据缓存器中的触控数据进行帧行锁定。相反，若目标帧频处理格式不是全帧频处理格式，即目标帧频处理格式为半帧频处理格式，则此时SOC可以响应于目标帧频处理格式为第二帧频处理格式，通过对控制数据缓存器中的触控数据的行时钟信号和帧时钟信号进行倍频处理，从而实现对数据缓存器中的触控数据进行倍频读取处理。之后，触控显示设备即可以同步显示出触控数据对应的图像。
其中，基于目标帧频处理格式进行帧频转换和设置数据缓存器按目标模式缓存数据可以称为图像处理通道配置。上述步骤502至步骤506可以称为调整扩展显示器识别数据(extended display identification data，EDID)。
步骤507、对基于触控数据输出的视频信号进行展频处理。
为了减少外界环境给基于触控数据输出的视频信号带来的电磁干扰(electro magnetic interference，EMC)，SOC可以在基于触控数据输出视频信号以供触控显示设备显示时，先对该视频信号进行展频处理。其中，该展频处理是指过对视频信号的尖峰信号进行调制处理，使其从一个窄带信号变为一个具有边带的频谱，将信号的尖峰能量分散到展频区域的多个频率段。
可选的，该视频信号可以通过V-B-O接口或LVDS接口输出视频信号。
需要说明的是，上述步骤均可以采用软件算法实现。本公开实施例以采用Bypass防护模式；请求优先级高的第一帧频处理格式为全帧频处理格式，请求优先级低的第二帧频处理格式为半帧频处理格式；目标模式为单帧FIFO模式；执行降噪、运动补偿和方向性关联的隔行扫描(direction correlational deinterlacing，DCDI)处理；展频处理视频信号中的时钟信号，且展频幅度为1.5％为例以软件代码示出上述执行方法：
{buffer＝＝单帧FIFO模式；       //设置数据缓存器按单帧FIFO模式工作
QDram EN；                      //控制DDRAM处于使能状态
Bypass noise reduction；       //设置降噪
Bypass motion compensation；  //设置运动补偿
Bypass DCDI；                //设置DCDI
Scaler＝＝0；                      //scaler功能算法置0
If{Display frame＝＝Input frame    //目标帧频处理格式为全帧频处理格式
DHclock＝＝locked；                //锁定行时钟信号
DVclock＝＝locked；               //锁定帧时钟信号
Else
DHclock＝＝dobule；                //倍频行时钟信号
DVclock＝＝dobule；                //倍频帧时钟信号
}
{Dclock＝＝Hintotal*Vintotal*Vfre；  //置时钟信号为行与帧与参考信号之积
Dclock spread spectrum＝＝1.5％；   //将时钟信号展频1.5％幅度
}
其中，Scaler功能算法是指一种针对不同分辨率的触控显示设备调整图像显示大小的算法。将Scaler功能算法置0是指不运行该算法。
需要说明的是，上述实施例提供的触控显示设备的触控响应方法步骤先后顺序可以进行适当调整，也可以根据情况进行相应增减，如步骤507可以根据情况进行删除。任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本公开的保护范围之内，因此不再赘述。
