具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本公开实施例中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外,本申请中使用“和/或”表示所连接对象的至少其中之一,例如A和/或B和/或C,表示包含单独A,单独B,单独C,以及A和B都存在,B和C都存在,A和C都存在,以及A、B和C都存在的7种情况。
相关技术中,像素充电所需的时间是一定的,为了提高显示效果,内嵌式触控显示面板需要具有足够高的画面刷新频率,相应的,画面显示时序的时长也随之增加,而为了提高触控精度,则需要具有足够高的触控采样频率,相应的,触控采样时序的时长也需要随之增加。
内嵌式触控显示面板的画面显示时序和触控扫描时序是冲突的,这对显 示面板的显示效果和触控采样效果精度均造成了一定的限制。
本公开实施例提供了一种显示控制方法,应用于显示装置,显示装置可以是笔记本电脑、智能一体机等显示装置,显示装置包括显示面板,且显示面板具体为内嵌式触控显示面板。
步骤101:获取所述显示装置的显示刷新频率。
本实施例中,显示装置在使用过程中,能够提供不同的显示刷新频率,具体而言,在一个实施例中,显示刷新频率包括第一刷新频率和第二刷新频率,所述第一刷新频率大于所述第二刷新频率。
需要理解的是,本实施例的技术方案中,显示装置的显示刷新频率是可以调节的,以满足不同的使用状态下,对于显示装置的显示刷新频率的不同需求。
示例性的,用户在玩射击类游戏时,对于画面显示的实时性有较高要求,显示装置的工作模式为非触控显示模式,该工作模式对应一个较高的显示刷新频率,示例性的,显示刷新频率可以是180Hz。
示例性的,用户观看高清视频时,对于画质有更高的要求,也需要具有较高的显示刷新频率,同时,用户可能通过触控执行暂停、继续等操作,此时,显示装置的工作模式为上述第三触控显示模式,该工作模式下,显示装置支持触控功能,且具有相对较高的显示刷新频率,示例性的,显示刷新频率可以是120Hz。
示例性的,用户在正常浏览网页时,显示刷新频率可以是90Hz,触控采样频率为。
示例性的,用户在通过手写功能绘图时,画面为基本静态的画面,在该工作模式下,较低的显示刷新频率即可满足使用需求,示例性的,显示刷新频率可以是60Hz。
需要理解的是,上述显示刷新频率仅用于做示例性说明,其具体数值并不局限于此。
步骤102:根据所述显示刷新频率确定所述显示面板对应的触控采样频率。
本实施例中,基于用户对于触控功能的不同需求,相应的,提供不同的 触控采样频率。
触控采样频率包括与第一刷新频率对应的第一采样频率和与第二刷新频率对应的第二采样频率,第二采样频率大于第一采样频率。
如图2所示,示例性的,用户在玩射击类游戏时,显示刷新频率为180Hz,此时,用户不需要进行触控操作,其对应的触控采样频率为0。
示例性的,用户观看高清视频的第三触控显示模式,显示刷新频率可以是120Hz,用户可能需要使用触控功能,其对应的触控采样频率为60Hz。
示例性的,用户在正常浏览网页的第二触控显示模式,显示刷新频率可以是90Hz,触控采样频率为90Hz,兼顾了画面质量和触控采样效果。
示例性的,用户在通过手写功能绘图的第一触控显示模式,显示刷新频率可以是60Hz,而画图过程对于触控笔迹的采样实时性和准确性具有更高的要求,因此,设置触控采样频率为120Hz,能够显著的提高触控采样精度和准确性,从而有助于更为准确的还原触控笔迹。
需要理解的是,上述显示刷新频率仅用于做示例性说明,其具体数值并不局限于此。
步骤103:根据所确定的显示刷新频率驱动所述显示面板显示图像,以及根据所述触控采样频率采集触控信息。
在确定了显示刷新频率和触控采样频率之后,根据所确定的显示刷新频率控制显示面板显示图像,以及根据所确定的触控采样频率采集触控信息,能够获得满足使用需求的显示效果以及触控显示效果。
如图1所示,在一个实施例中,步骤101之前,该方法还包括:获取所述显示装置的工作模式。
相应的,步骤101具体包括:获取与所述工作模式对应的显示刷新频率
本实施例的技术方案中,显示装置具有多种不同的工作模式,在其中一个实施例中,显示装置具有非触控显示模式和触控显示模式两种工作模式,在非触控显示模式下,该显示面板的触控功能处于关闭状态,而在触控显示模式下,该显示面板支持触控功能。
本实施例中,可以通过不同的方式确定显示装置的工作模式。
在一个示例性的实施例中,可以根据用户的操作输入选中相应的工作模 式。
以显示装置为笔记本电脑或个人计算机做示例性说明,用户可以通过特定的实体按键或虚拟按键切换显示面板的工作模式,与用户也可以通过鼠标、键盘等在指定的控制菜单中切换显示面板的工作模式,用户还可以通过语音控制、遥控器、触摸板等其他方式提供上述操作输入。
当显示装置的类型发生变化时,可以根据需要做出适应性调整。示例性的,对于部分手机或平板电脑来说,其控制必须依赖触控输入,则可以通过触控的方式选择触控显示输入对应的不同工作模式。
在一些实施例中,所述获取所述显示装置的工作模式包括:
在满足以下任一条件的情况下,确认所述显示装置的工作模式为非触控显示模式:
检测到基于第一类型外设提供的操作输入;
接收到关闭触控功能的操作输入;
检测到第一类型应用程序处于运行状态。
在一些实施例中,所述第一类型外设包括鼠标、键盘和游戏外设中的一项或多项。
在一个示例性实施例中,显示装置为笔记本电脑,用户基于鼠标、键盘进行操作时,同时使用触控功能的可能性较小,因此,在这种情况下,可以将显示装置的工作模式切换为非触控显示模式。
类似的,当用户使用游戏手柄,或者方向盘、感应枪等游戏模拟器外设时用户使用触控功能的可能性较小,此时,可以确定电子设备的工作模式为非触控显示模式。
在另外一些实施例中,用户可以基于操作输入主动关闭触控功能,从而进入非触控显示模式。
在另外一些实施例中,当特定的第一类型应用程序运行时,用户使用触控功能的可能性也较小,示例性的,用户游戏或观看高清视频时,对于显示效果要求较高,画面需要具有较高的刷新频率,而对于触控功能有需求的可能性相对较小。在一些实施例中,第一类型应用程序包括游戏程序和视频播放器中的一项或多项。这样,当显示装置运行这些第一类型的应用程序时, 进入非触控显示模式。
在一些实施例中,所述获取所述显示装置的工作模式包括:
在满足以下任一条件的情况下,确认所述显示装置的工作模式为触控显示模式:
检测到主动式触控笔处于工作状态;
接收到开启触控功能的操作输入;
通过摄像头检测到触控输入的动作;
检测到第二类型应用程序处于运行状态。
本实施例的技术方案中,如果检测到主动式触控笔处于工作状态,则用户很可能基于该主动式触控笔进行工作,而用户使用主动式触控笔的过程中,必然会使用触控功能。
在另外一些实施例中,可以通过摄像头基于图像识别确认用户是否执行了触控操作。
需要理解的是,如果显示装置处于非触控显示模式,则执行的触控操作无法被显示面板所识别,因此,本实施例中需要通过摄像头采集触控输入的动作以开启触控显示模式对应的工作模式。
在一些实施例中,开启触控功能的操作输入不仅可以参考上述实施例,还可以通过手势命令实现,示例性的,当摄像头采集到特定的手势动作时,控制显示面板进入触控显示模式。
在一些实施例中,可以通过判定第二类型应用程序是否处于运行状态以确定是否进入触控显示模式,在一些实施例中,所述第二类型应用程序包括文档处理程序和绘图程序中一项或多项。
需要理解的是,第一类型应用程序可以包括游戏程序,第二类型应用程序同样可以包括游戏程序,例如,对于射击或动作类游戏来说,对于画面刷新实时性要求较高,且通常不需要触控输入,则可以确定其对应非触控显示模式,而对于消除类游戏等对于性能要求较低的游戏,则可以确认其对应第二类型应用程序。实施时,应当根据应用程序对于硬件性能、显示需求和输入习惯等因素确定应用程序对应的类型。
示例性的,用户在使用绘图程序时,使用触控输入较为便利,此时,进 入触控显示模式对应的工作模式。又如,用户在使用幻灯片展示、文档展示等功能时,背景为相对静态的画面,同时,用户还可能通过手写的方式输入一些批注或标记,此时,对于画面的刷新频率要求相对较低,而对于触控识别的要求相对较高。此时,基于该需求,可以确定相应的工作模式。
在一些实施例中,工作模式包括与第一刷新频率对应的非触控显示模式和与第二刷新频率对应的触控显示模式。
在其中一些实施例中,第一采样频率为0,第一刷新频率大于0,显示装置的工作时序包括依次设置的多个画面刷新时段,显示装置一帧的工作时序对应一个画面刷新帧。可以理解为,在这一情况下,关闭了显示面板的触控采样功能。
在非触控显示模式,显示装置能够达到最高的显示刷新频率,这种情况下,该非触控显示模式对应的显示刷新频率为第一刷新频率,非触控显示模式对应的触控采样频率为第一采样频率。
在另外一个实施例中,工作模式包括对应不同显示刷新频率的多个触控显示模式,具体而言,触控采样频率均大于0,显示刷新频率均大于0,显示装置一帧的工作时序包括交替设置的画面刷新时段和触控扫描时段,显示装置一帧的工作时序中的全部画面刷新时段对应一个画面刷新帧。
示例性的,多个触控显示模式可以是具有较低显示刷新频率的低刷新频率模式和具有较高显示刷新频率的高刷新频率模式。
需要理解的是,该显示面板还可以包括更多数量的工作模式,例如,该显示面板可以包括具有不同显示刷新频率的三种工作模式,示例性的,按照显示刷新频率由低到高可以将各工作模式记作低功耗模式、均衡模式和高性能模式。
需要理解的是,其命名并不局限于此,示例性的,低功耗模式也可也称作节能模式、高性能模式也可也记作游戏模式等。
需要理解的是,该显示面板的工作模式的数量并不局限于此,其数量可以进一步增加,例如,设置四种、五种、六种甚至更多数量的工作模式,此处不做进一步限定和描述。
在另外一些实施例中,上述两种方式是可以结合的,具体而言,该显示 面板可以包括开启触控功能的触控显示模式和关闭触控功能的非触控显示模式,其中,触控显示模式和非触控显示模式均可以包括多个不同数量的、具有不同显示刷新频率的工作模式。
示例性的,对于触控显示模式来说,其包括三个具有不同显示刷新率的工作模式,而非触控显示模式也包括三个具有不同显示刷新频率的子工作模式。此时,显示面板可以理解为包括六种不同的工作模式。
实施时,触控显示模式和非触控显示模式对应的子工作模式的数量均可以做出调整,其数量并不局限于此。
在其中一个实施例中,该显示面板的工作模式具体包括一个非触控显示模式、第一触控显示模式、第二触控显示模式和第三触控显示模式三种触控显示模式,这样,该显示面板共计包括四种工作模式。本实施例中以此做示例性说明。
在非触控显示模式下,每一帧工作时序均由连续设置的多个画面刷新时段构成,且每一帧工作时序对应一个画面刷新帧。
在触控显示模式下,显示装置一帧的工作时序包括交替设置的画面刷新时段和触控扫描时段,显示装置一帧的工作时序中的全部画面刷新时段对应一个画面刷新帧。
进一步的,在一些实施例中,在触控显示模式下,在第一触控显示模式和第二触控显示模式下,显示装置的每一帧工作时序的画面刷新时段和触控扫描时段的时长比例不相等。
本实施例的技术方案中,在非触控显示模式下,触控采样识别对应的第一采样频率为0,换句话说,触控采样处于关闭状态。
在触控显示模式下,显示面板的工作时序包括画面刷新时段和触控扫描时段,画面刷新时段和触控扫描时段交替设置的。
本实施例的技术方案中,在触控显示模式下,不同的具体工作模式中,画面刷新时段和触控扫描时段的比例是不同的。
如图2所示,相邻两条虚线之间代表180Hz对应的一帧工作时序,图中D代表一个画面刷新单位时长,T代表一个触控扫描单位时长,以触控扫描单位时长和画面刷新单位时长相等做示例性说明。
图2中第一条时序图对应非触控显示模式,该一帧工作时序包括依次设置的8个画面刷新单位时长,这8个画面刷新时段对应一个画面刷新帧。
示例性的,用户观看高清视频的第三触控显示模式,显示刷新频率可以是120Hz,触控采样频率为60Hz,画面刷新时段和触控扫描时段的时长比例是2:1。
具体的,第三触控显示模式下,一帧工作时序包括12个单位时长,一个画面刷新时段对应两个画面刷新单位时长,一个触控扫描时段对应一个触控扫描时段,也就是说,每执行两个单位时长的画面刷新,执行一个单位时长的触控扫描。每8个单位时长对应一个画面刷新帧或触控扫描帧,则显示刷新频率可以是120Hz,触控采样频率为60Hz。
如图2中的第二条时序图所示,示例性的,用户在正常浏览网页的第二触控显示模式,显示刷新频率可以是90Hz,触控采样频率为90Hz,,画面刷新时段和触控扫描时段的时长比例是1:1。
具体的,一帧工作时序包括16个单位时长,一个画面刷新时段对应一个画面刷新单位时长,一个触控扫描时段对应一个触控扫描单位时长,也就是说,每进行一个单位时长的画面刷新,进行一个单位时长的触控扫描。
如图2中第三条时序图所示,示例性的,用户在通过手写功能绘图的第一触控显示模式,显示刷新频率可以是60Hz,触控采样频率为120Hz,画面刷新时段和触控扫描时段的时长比例是1:2。
具体的,一帧工作时序包括24个单位时长,本实施例中,一个画面刷新时段对应一个画面刷新单位时长,一个触控扫描时段对应两个触控扫描单位时长,也就是说,每进行一个单位时长的画面刷新,进行两个单位时长的触控扫描。
显然,实施时,可以根据需要调整,画面刷新时段和触控扫描时段的比例,其数值并不局限于此。
在一些实施例中,每一帧工作时序包括的各画面刷新时段对应一个画面刷新帧,每一帧工作时序包括的各触控扫描时段对应m个触控扫描帧,m为大于0的整数或小数。
示例性的,画面刷新时段和触控扫描时段的时长比例是1:1.5,每一帧工 作时序对应一个画面刷新帧,则两帧工作时序对应三个触控扫描帧。
以显示面板包括1600条显示扫描线和1600条触控扫描线做示例性说明,在上述非触控显示模式下,显示面板在正常工作状态下,最大额定显示刷新频率为180Hz,则显示扫描线扫描时间为1(秒)/180(Hz)/1600(条)=3.47微秒。
该3.47秒可以理解为显示面板的扫描线(具体为显示扫描线或触控扫描线)能够达到的最短扫描时间,即对应上述一个单位时长。
换句话说,每一显示扫描线或触控扫描线的扫描时间为3.47微秒,这样,当画面刷新频率为120Hz时,触控扫描频率为60Hz,当画面刷新频率为90Hz时,触控扫描频率为90Hz。
这样,在需要提高画面更新速度或提高画面显示质量时,可以具有较高画面刷新频率的工作模式,当执行手写笔迹识别等需要对触控采样具有较高精度要求时,则选择具有较高触控采样频率的工作模式。
在一些实施例中,在显示装置的显示刷新频率位于第一刷新频率区间时,显示装置对应第一触控显示模式,在显示装置的显示刷新频率位于第二刷新频率区间时,显示装置对应第二触控显示模式,第一刷新频率区间和第二刷新频率区间不交叠。
如图3所示,本实施例的技术方案中,在每接收到一帧图像时,可以先检测是否处于触控显示模式,本实施例中,可以通过开关触控暂存器保存的标识符表示触控状态,示例性的,如果标识符EN=0,则对应非触控显示模式,此时,根据数据源(例如显卡)提供的信号对应的显示刷新频率进行显示扫描以显示图像,这一情况下,显示面板的刷新频率可以根据需要提高至最高状态,以提供最好的显示效果。
如果标识符EN=1,则对应非触控显示模式,此时,可以根据数据源提供的信号确定相应的刷新频率。
示例性的,如果数据源提供的信号的画面刷新频率F小于或等于60Hz,则触控采样频率X确定为120Hz;如果数据源提供的信号的画面刷新频率F大于60Hz且小于或等于90Hz,则将触控采样频率X确定为90Hz;如果数据源提供的信号的画面刷新频率F大于90Hz且小于或等于120Hz,则将触控 采样频率确定为60Hz。之后,根据显示刷新频率和触控采样频率进行图像显示和触控识别。
上述小于或等于60Hz、大于60Hz且小于或等于90Hz、大于90Hz且小于或等于120Hz即为所确定的不同显示刷新频率区间。
需要理解的是,上述数值仅用于做示例性说明,并不局限于此。
