Description
本申请要求于2019年01月29日提交中国专利局,申请号为CN201910018512.3,申请名称为“一种显示装置及其驱动方法和显示器”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及显示技术领域,尤其涉及一种显示装置及其驱动方法和显示器。
这里的陈述仅提供与本申请有关的背景信息,而不必然地构成现有技术。
随着液晶显示面板技术的发展,消费者对显示效果的要求越来越高,液晶显示面板的解析度也逐渐向4K2K(UHD)及8K4K发展。4K2K超高清可达到3840×2160的物理分辨率,是普通FullHD(1920×1080)宽高的各两倍,面积的四倍,显示设备的总像素数量达到了800万以上。
为了显示效果更佳,出现了双栅极驱动的像素结构,为了使该种像素结构能够得到满意的画面品质,需要搭配更好的数据反转方式,比如双行反转(2line inversion)或一加二行反转(1+2line inversion)。但这种驱动方式的像素结构对驱动芯片的功率消耗较大,温度也会很高,需要外加散热措施(比如散热贴)来保证内部温度的平衡。
发明内容
本申请的目的提供一种显示装置及其驱动方法和显示器。
为实现上述目的,本申请提供了一种显示装置,包括:显示面板、驱动显示面板的时序控制器、存储在所述时序控制器内的闪烁图像以及连接所述时序控制器的外接引脚的使能信号;当所述显示面板显示预设画面时,所述时序控制器根据所述使能信号直接输出所述闪烁图像至显示面板。
本申请还提供一种显示装置的驱动方法,所述显示装置包括显示面板和时序控制器,所述驱动方法包括:
在时序控制器中预存闪烁图像;
检测显示面板的待显示画面;以及
输出闪烁图像:当所述显示面板显示预设画面时,所述时序控制器根据所述使能信号直接输出所述闪烁图像至显示面板
本申请还公开了一种显示器,包括显示装置,所述显示装置包括,显示面板、驱动显示面板的时序控制器、存储在所述时序控制器内的闪烁图像以及连接所述时序控制器的外接引脚的使能信号;当所述显示面板显示预设画面时,所述时序控制器根据所述使能信号直接输出所述闪烁图像至显示面板。
相对于借由存有许多闪烁图像的测试辅助技术人员调整面板的最佳供电压电位,由于闪烁图像的数量庞大,容易出现输出的闪烁画面不正确等问题。本申请对硬件没有太多改动,只是在时序控制器(T-CON)内增设一张用于调整共电压的闪烁图像,不必设置样式生成器,并且由于闪烁图像是时序控制器自带的,根据预设画面自动出现,可以在正确的时机输出闪烁图像,所以不会出错。

下面参考附图和可选的实施例对本申请作进一步说明。
如图1至图9所示,本申请实施例公布了一种显示装置100包括:显示面板130,被配置为驱动显示面板130的时序控制器200,存储在所述时序控制器200内闪烁图像110,和连接所述时序控制器200的外接引脚;使能信号120;当所述显示面板130显示预设画面时,所述时序控制器200根据所述使能信号120直接输出所述闪烁图像110至显示面板130。
相对于借由存有许多闪烁图像110的测试辅助技术人员调整面板的最佳供电压电位,由于闪烁图像110的数量庞大,容易出现输出的闪烁画面不正确等问题。本申请对硬件没有太多改动,只是在时序控制器200(T-CON)内增设一张用于调整共电压的闪烁图像110,不必设置样式生成器,并且由于闪烁图像110是时序控制器200自带的,根据预设画面自动出现,可以在正确的时机输出闪烁图像110,所以不会出错。
具体的,如图4所示,所述时序控制器200还包括存储器140和输入输出引脚150,所述闪烁图像110存储在所述存储器140中,所述使能信号120连接所述输入输出引脚150;所述时序控制器200根据所述使能信号120从所述存储器140中读取闪烁图像110,然后直接输出所述闪烁图像110至显示面板130。闪烁图像110存储在时序控制器200内的存储器140中,因为存储器140本身就用于存储一些图像和配置的修复元件,将闪烁图像110直接存储在时序控制器200的存储器140中,不影响其他模块功能的运作,也方便实现。
所述时序控制器200还包括总线控制器160;所述存储器140通过总线控制器160与所 述输入输出引脚150连接。在存储器140通过时序控制器200预留的输入输出引脚150连接,总线控制器160将外部引线与存储器140相连,说明连接高低电平,当不需要调整供电压时,输出闪烁图像110时,使能信号120120拉低,T-CON正常工作,接收到RGB信号后经RGBW转换,以迷你低压差分信号传输(mini-Low Voltage Differential Signaling,mini-LVDS)或P-P接口输出给显示面板130的源极驱动芯片170,然后输出到显示面板130内;当需要做闪烁调整时,使能信号120的引脚拉高时,T-CON输出内建的闪烁图像110至面内。
所述存储器140为带电可擦可编程读写存储器140或闪存;所述总线控制器160为同步外设接口控制器或内置集成电路控制器。
内置集成电路(Inter Integrated Circuit,IIC)包括一个时钟线和一个数据线。只有一根数据线,所以是半双工通信。优点是接线简单,而且两根线上也可以挂很多设备。
同步外设接口(Serial Peripheral Interface,SPI),由一个主设备和一个或多个从设备组成,主设备启动一个与从设备的同步通讯,从而完成数据的交换,数据交换速度比较快。
存储器140为带电可擦可编程读写存储器140(Electrically Erasable Programmable read only memory,EEPROM),是用户可更改的只读存储器140(ROM),可以擦除和重编程。保证以后如何需要调整更换闪烁图像110时,不需要重新配置存储器140,显示面板130的耐用度也就会更长久。
闪存(flash)是一种非易失性内存,在没有电流供应的条件下也能够长久地保持数据,其存储特性相当于硬盘。
使能信号除了可以接入输入输出引脚,还可以接入时序控制器的其他引脚。如图6所示,所述时序控制器200还包括自测电路210和测试引脚,所述测试引脚直接连接所述自测电路210;所述闪烁图像110存储在所述自测电路210中;所述使能信号120连接所述测试引脚;所述时序控制器200根据所述使能信号120从所述自测电路210中读取闪烁图像110,然后直接输出所述闪烁图像110至显示面板130。
因为时序控制器200的自测电路210模块里本来就有多张用于老化测试用的循环滚动图像,增加一张闪烁图像110基本上不会增加成本或受到影响,对硬件没有太多改动,并且由于闪烁图像110是时序控制器200内部的自测电路210输出,自动出现,不必挑选,所以不会出错。
在一实施例中,所述时序控制器200还包括数据接收机220、图像质量处理单元230、过压驱动单元240、行缓冲单元250、交换控制单元260、输入输出引脚150、通信引脚170、总线控制器160和存储器140;其中,待显示的显示数据通过所述数据接收机220、自测电路210、图像质量处理单元230、过压驱动单元240、行缓冲单元250、交换控制单元260和通信引脚170输出至所述显示面板130;所述总线控制器160通过总线分别连接所述数据接 收机220、自测电路210、图像质量处理单元230、过压驱动单元240、行缓冲单元250、交换控制单元260、输入输出引脚150和存储器140。闪烁图像110因要经过输送到显示面板130需要绕过很多走线,从而不影响其他模块功能的运作,而总线控制器160与时序控制器200内部所有模块分别连接,可缩短闪烁输出至显示面板130的时间,快速调整显示面板130出现的闪烁情况。
具体的,所述自测电路210中仅存储有一幅所述闪烁图像110。自测电路210中本身的多张循环滚动的画面替换成一张限定的闪烁图像110,如图4所示,当需要自测电路210接到高电平时,整个显示装置100进入自由模式,从而无论前端输出任何信号,都显示此张闪烁画面,没有多张图像进行挑选,只有一张,所以可以保证输出正确的闪烁图像110。将闪烁图像110做在T-CON自测电路210中,整个架构如图5所示,通过使能信号120将测试引脚拉出到接口做控制,当使能信号120为低电平信号时,T-CON正常工作,接收到RGB信号后经RGBW转换,以mini-LVDS或P-P接口输出给源极驱动芯片170,然后输出到显示面板130内;当使能信号120的电平拉高时,T-CON启动自测电路210,无论前段接收的信号是什么,T-CON都输出内建的闪烁图像110(flicker pattern)至显示面板130内。
所述显示面板还包括多个子像素;所述子像素包括,行方向上排列的红色像素R、绿色像素G、蓝色像素B以及白色像素W;列方向上有且只有两个所述子像素交替排列,同一列上的所述子像素极性相同,相邻两列的所述子像素极性不同,颜色也不同;所述红色像素R与所述蓝色像素B位于同一奇数列,所述绿色像素G和所述白色像素W位于同一偶数列;相邻的两个奇数列或两个偶数列,在行方向上的所述子像素颜色不同。
比起普通RGB的三个子像素,增加了一个白色的子像素W,能提高面板的穿透率,背光就可以做的更暗,达到省功耗的目的。并且,如图1和图2所示,奇数列中红色像素和蓝色像素交替排列,并且极性相同;偶数列中白色像素和绿色像素交替排列,并且极性相同;相邻的两行子像素极性相同,颜色不同,在极性驱动极性反转时相当于列反转,比起普通显示面板用双栅极反转(2line inversion)或一加二行反转(1+2line inversion)对数据驱动电路的功耗减小,可以避免内部温度过高,损坏电路或芯片。
另外,相邻的两个奇数列上的子像素,在行方向上颜色不同,都为红色像素和蓝色像素交错排列的第一列和第三列,但在第一列中红色像素位于第一行,在第三列中红色像素位于第二行;同样的,偶数列上的绿色像素和白色像素每隔一列,行方向的排列顺序相反。这样排列多个子像素,使白色像素在显示面板中分布更均匀,面板亮度平衡。

具体的,所述时序控制器200还包括存储器140和输入输出引脚150,所述闪烁图像110存储在所述存储器140中,所述使能信号120连接所述输入输出引脚150;所述时序控制器200根据所述使能信号120从所述存储器140中读取闪烁图像110,然后直接输出所述闪烁图像110至显示面板130。
