当然,以上举例是示例性的,本领域技术人员也可以采用其他的调整模式对显示图像进行调整,如每一次调整的调整值均可以不同,或针对图像的不同区域设置不同的调整值,在一个示例中,对于一幅图像的不同色彩区域,本公开实施例可以具有不同的调整幅度,以提高处理的适应性、灵活性,并提高用户体验,提高图像显示的真实性,例如,显示图像中无色彩区域像素点的调整值可以大于有色彩像素点的调整值,例如对于黑色区域的调整值可以大于彩色区域的调整值。
在一个示例中,存储模块可以包括计算机可读存储介质,计算机可读存储介质可以 是可以保持和存储由指令执行设备使用的指令的有形设备。计算机可读存储介质例如可以是――但不限于――电存储设备、磁存储设备、光存储设备、电磁存储设备、半导体存储设备或者上述的任意合适的组合。计算机可读存储介质的更具体的例子(非穷举的列表)包括:便携式计算机盘、硬盘、随机存取存储器(RAM)、只读存储器(ROM)、可擦式可编程只读存储器(EPROM或闪存)、静态随机存取存储器(SRAM)、可编程只读存储器(PROM)、便携式压缩盘只读存储器(CD-ROM)、数字多功能盘(DVD)、记忆棒、软盘、机械编码设备、例如其上存储有指令的打孔卡或凹槽内凸起结构、以及上述的任意合适的组合。在一个示例中,存储模块还可以包括寄存器组。
在一个示例中,在预设调整值集合中,各个像素调整值的大小可以是不同,也可以设置间隔的像素调整值相同、而相邻的像素调整值不同,对此,本公开实施例不做限定。本公开实施例对预设调整值集合中各个像素调整值的具体大小不做限定,本领域技术人员可以根据需要或实际情况确定。
在一个示例中,当显示图像为RGB图像时,本公开实施例可以直接对RGB图像格式的显示图像的各个像素进行调整,以得到中间图像,并根据中间图像的R、G、B通道的像素值产生驱动信号,以对对应的像素灯进行驱动。
在一种可能的实施方式中,所述根据所述中间图像驱动所述显示面板进行显示,包括:在所述中间图像不为RGB图像的情况下,对所述中间图像进行颜色空间转换处理,以将所述中间图像转换为RGB图像;根据颜色空间转换处理后的中间图像产生驱动信号,驱动所述显示面板以预设时间为间隔进行动态显示。

请参阅图2,图2示出了根据本公开一实施例的显示驱动方法的流程图。
在一种可能的实施方式中,如图2所示,所述方法还可以包括:

在一种可能的实施方式中,所述显示图像的图像格式包括RGB图像、YUV图像、HSV 图像、HSL图像和YCbCr图像等的任意一种,本公开实施例对显示图像的图像格式不做限定。在一个示例中,以RGB图像为例,本公开实施例可以对显示图像的R通道、G通道、B通道的至少一个进行调整;以HSV图像为例,本公开实施例可以对显示图像的H通道、S通道、V通道的至少一个进行调整;以HSL图像为例,本公开实施例可以对显示图像的H通道、S通道、L通道的至少一个进行调整;以YCbCr图像为例,本公开实施例可以对显示图像的Y通道、Cb通道、Cr通道的至少一个进行调整。通过以上方法,本公开实施例可以把原本物理空间上的变化,转化至颜色空间上的变化,维持整体画面在面板上位置不变,达成像素内容的轮动,推迟或放置图像烙印、残影的发生,提升用户体验。
请参阅图3a、图3b,图3a、图3b示出了图像显示的示意图。
在一个示例中,若显示面板长时间显示如图3a所示的显示图像,则显示面板会留下如图3b所示的屏幕残影,当显示面显示其他图像时,势必会对其他图像的准确显示造成影响,并降低用户的观看体验,通过以上方法,本公开实施例仅对像素的显示颜色、灰阶进行调整,不改变一帧图像中各元素在屏幕上的显示位置,在一定时间中,以预设时长为间隔,使得一帧图像呈现多种颜色组态或灰阶养胎,避免在屏幕上长时间显示静态显示该图像时,出现屏幕残影、烙印现象,例如,可以消除如图3b所示的屏幕残影,使得后续对其他显示图像的显示更准确,用户体验更好。
