以下结合本说明书的附图,对本申请的较佳实施方式予以进一步地详尽阐述。
实施例一
本申请的技术方案可以应用在LCD(Liquid Crystal Display,液晶显示)中,也可以用在有机发光二极管(Organic Light-Emitting Diode,OLED)中。
参阅图1和图2所示,本申请公开了一种显示装置10,显示装置10包括显示面板110,显示面板110具有多个像素单元,比如像素单元的数量为m行,n列,则像素单元构成m*n矩阵的显示面板110。像素单元包括有供电端,通过供电端向像素单元供电,保证像素单元能够正常显示。显示装置10还包括:时序控制模块120和电源模块130,时序控制模块120和电源模块130通常设置于显示面板110的边框位置,在边框位置能够减少对光线的遮挡,保证显示画面正常。
时序控制模块120具有第一信号输出端和第二信号输出端,第一信号输出端用于输出选择指令信号(Step),第二信号输出端用于输出时钟信号(CLK);电源模块130连接时序控制模块120,电源模块130能够接收时钟信号和选择指令信号。并且,电源模块130依据选择指令信号和时钟信号生成供电电压,并将供电电压提供至像素单元的供电端;通过供电电压保证像素单元的正常显示工作。
进一步地,电源模块130包括:电压产生单元131、电压选择单元132和电压转化单元133,电压产生单元131用于生成多个阶跃电压(step voltage),电压值从一个值跳变到另一个值称为阶跃电压,比如从0跳变到0.1。阶跃电压是电压产生单元131输出的最小跨度电压,例如0.1V、0.2V或是0.5V等;电压选择单元132与第一信号输出端和电压产生单元131连接,电压选择单元132用于响应选择指令信号,在多个阶跃电压中选择至少一个阶跃电压,并将该阶跃电压输出给电压转化单元133。需要说明的是,电压产生单元131生成的多个阶跃电压的大小是相等的;电压转化单元133分别连接第二信号输出端和电压选择单元132,电压转化单元133接收到时钟信号后,电压转化单元133响应时钟信号,在阶跃电压的基础上确定供电电压。电压转化单元133还与供电端连接,以用于将供电电压输出至供电端。时钟信号是周期变化的波形信号,以阶跃电压为基础,通过时钟信号的变化确定供电电压,继而实现精细化调节。
本实施例的技术方案中,时序控制模块120生成时钟信号和选择指令信号。电压选择单元132响应选择指令信号,在多个阶跃电压中选择至少一个阶跃电压,并将这个阶跃电压输出给电压转化单元133。电压转化单元133接收到这个阶跃电压后,以这个阶跃电压为基础,依据时钟信号确定供电电压。可以理解的是,阶跃电压能够随着时钟信号的变化而生成不同的供电电压。由此,供电电压能够根据时钟信号进行精细化调节,满足亮度调节要求。
需要进一步指出的是,本申请中通过时序控制模块120直接连接电源模块130,直接向电源模块130传输时钟信号,信号的延迟时间更小。
另外,相比用在背光控制的PWM(Pulse width modulation)脉冲宽度调制信号,本方案能够实现更精细化调节。PWM信号通常用在恒压源上,控制恒压源只有通和断两种结果,调节的亮度跨度较大,亮度分布是离散的。而通过时钟信号调节,时钟信号的精度较高,在已经产生阶跃电压的基础上,进行二级调节。进一步细化阶跃电压的数值,在0.1V的基础上还能够进一减小电压。从而时钟信号控制的电压升降是连续的,精细化程度更高。
还需要指出的是,通过时钟信号的控制,能够减少电阻的使用。不需要通过设置大量电阻来细化电压,在设置了满足产生阶跃电压的电阻后,通过时钟信号的占空比和阶跃电压相乘的方式来细化电压。
为了能够清楚了解亮度的调整方向,时序控制模块120还具有侦测信号接收端。显示装置10还包括侦测模块140,侦测模块140连接侦测信号接收端,侦测模块140用于侦测环境亮度,并将侦测的环境亮度经侦测信号接收端输入至时序控制模块120的内部。时序控制模块120用于依据环境亮度生成选择指令信号和时钟信号。侦测模块140为光线传感器,光线传感器通过接收显示装置10周围光线数量,以此来判断显示装置10的环境亮度。
在环境亮度和显示面板110的亮度差异较大时,可以通过生成的时钟信号,提高供电电压的调整跨度,从而尽快使显示面板110的亮度和环境亮度符合,保证用户能够看清显示画面。或者是,尽快降低显示面板110的亮度,避免显示面板110的亮度过亮,刺痛人眼。
在环境亮度和显示面板110的亮度差异较小时,可以通过生成的时钟信号,减小供电电压的调整跨度,使用户能够找到显示面板110与环境亮度相适应的显示亮度,实现精细调节。
参阅图3所示,本申请的技术方案应用在机发光二极管的显示面板110中,像素单元包括有机发光二极管113,像素单元的供电端为有机发光二极管113的阴极或阳极,有机发光二极管113的阴极或阳极连接电源模块130。像素单元还包括第一响应开关T1、第二响应开关T2和电容C,第一响应开关T1的第一端连接数据线112,第一响应开关T1的第二端连接电容C的第一端,第一响应开关T1的控制端连接扫描线111。第二响应开关T2的第一端连接工作电压端(ELVDD),电容C的第二端连接第二响应开关T2和工作电压端之间的线路,第二响应开关T2的控制端连接第一响应开关T1的第二端和电容C之间的线路。第二响应开关T2的第二端连接有机发光二极管113的阳极,有机发光二极管113的阴极连接公共接地端(ELVSS)。第一端为信号输入端,第二端为信号输出端,响应开关的控制端为栅极,响应开关的第一端为源极,响应开关的第二端为漏极。
其中,有机发光二极管113的阴极连接电源模块130,可以理解为公共接地端连接电源模块130,有机发光二极管113的阳极连接电源模块130,可以理解为工作电压端连接电源模块130。由此可知,供电电压可以在发光二极管的阳极端进行调节,也可以在发光二极管的阴极端进行调节。发光二极管发光需要一个电路闭合的回路,在回路上的一点就可以完成电压大小的调节,从而控制发光二极管的亮度。
参阅图4所示,本申请的技术方案应用在液晶显示面板中,在液晶显示面板110中经常采用显示变频技术,来实现显示面板110的动态刷新率。动态刷新率通过对兼容显示器的刷新率和用户显卡的帧速率进行同步,最大限度地缩短输入延迟,并减少或完全消除卡顿花屏和撕裂问题。显示面板110的一帧分为显示时间Active(活跃)区和进入下一帧前的停顿Blank(空白)区。
假设以动态刷新率在48Hz-240Hz的显示面板110为例,显示面板110的分辨率是1920*1080,总共需扫描充电1080行,这1080行充电时间就是Active区,然后停顿45 行,这45行充电时间就是Blank区,动态刷新率就是通过改变Blank区时间行数改变刷新率。例如,低刷新率时,延长Blank区,高刷新率时缩短Blank区。但是,液晶显示面板110通过扫描充电后在液晶两侧维持压差来维持亮度,由于在Blank区时,液晶两侧会缓慢漏电。如果Blank区时间过长,漏电严重,显示面板110的亮度会出现变化。导致刷新率切换就会出现肉眼可感的亮暗变化。
为此,本申请的技术方案中,像素单元包括驱动晶体管T0、像素电极、公共电极和液晶层,驱动晶体管T0的控制端连接扫描线111,驱动晶体管T0的第一端连接数据线112,驱动晶体管T0的第二端连接像素电极,公共电极连接供电端,像素电极和公共电极位于液晶层的两侧,像素电极和公共电极形成液晶电容C1。液晶电容C1产生调节电压,调节电压作用在液晶层上,从而改变液晶层中液晶分子的转动方向。电源模块130用于向液晶电容C1的公共电极提供供电电压。在空白区,通过电源模块130向液晶电容C1提供的供电电压,实现对液晶电容C1的电压精细调节,进而更准确的控制液晶分子的转向。
进一步地,像素单元还包括公共信号线,公共信号线和像素电极同层设置,公共信号线和像素电极绝缘间隔,公共信号线和公共电极形成存储电容C2,公共信号线连接供电端。液晶电容C1和存储电容C2并联,电源模块130通过向存储电容C2充电,存储电容C2通过电容耦合维持液晶电容C1的电压,在空白区对液晶电容C1的电压进行补偿,补偿漏电量,由此减少液晶分子由于漏电导致的转动,保持液晶分子的转动状态不变,减少频率切换时的明暗变化。
参阅图5所示,本申请的显示面板110中,为了避免液晶分子极化,通常交替给像素单元施加正负交替的电压,从而避免液晶分子受到单一极性电压导致极化。像素单元的显示极性有两种,一种正极性显示,另一种负极性显示。具体地,多个像素单元包括第一子像素101和第二子像素102,第一子像素101和第二子像素102的显示极性相反,电源模块130分别连接第一子像素101的供电端和第二子像素102的供电端,电源模块130用于向第一子像素和第二子像素正负极性相反的供电电压。
第一子像素101和第二子像素102可以交替分布在显示面板110上,同一条数据线112上的显示极性相同。比如,第一子像素101正极性显示,第二子像素102负极性显示。如果,第一子像素101负极性显示,第二子像素102正极性显示。对第一子像素101和第二子像素102分开供电,针对性更强。需要说明的是,第一子像素101和第二子像素102的正负极性是交替变化的。其中,正极性是指,供电电压大于液晶电容C1的公共电极的电压,负极性是指,供电电压小于液晶电容C1的公共电极的电压。
实施例二
参阅图6所示,本申请还提供一种显示方法,显示方法应用于驱动显示面板,显示面板具有多个像素单元,像素单元包括有供电端,显示面板为有机发光二极管或者是液晶显示面板,显示方法包括:
步骤S10,生成选择指令信号和时钟信号;选择指令信号用于控制选择阶跃电压,时钟信号是周期变化的脉冲信号,通常是方波形脉冲信号。
步骤S20,生成多个阶跃电压,依据选择指令信号在多个阶跃电压中选择至少一个阶跃电压。
步骤S30,依据时钟信号在阶跃电压的基础上确定供电电压,并将供电电压输出至供电端。时钟信号是周期性变化的,阶跃电压依据时钟信号,同样也可以产生周期性的变化,阶跃电压是最小跨度电压,通过和时钟信号结合,能够达到小于阶跃电压的电压,从而实现供电电压的精细化调节。
本实施例的技术方案中,依据选择指令信号,在多个阶跃电压中选择至少一个阶跃电压,并以这个阶跃电压为基础,依据时钟信号确定供电电压。可以理解的是,阶跃电压能够随着时钟信号的变化而生成不同的供电电压。由此,供电电压能够根据时钟信号进行精细化调节,满足亮度调节要求。
参阅图7所示,为了能够清楚了解亮度的调整方向,生成选择指令信号和时钟信号的步骤,包括:
步骤S110,获取环境亮度,基于环境亮度生成选择指令信号和时钟信号。其中,不同环境亮度生成的时钟信号的占空比不同。占空比是时钟信号的脉冲宽度和脉冲周期的比值。脉冲宽度就是时钟信号中高电平的时间长度,脉冲周期就是一个完整脉冲波形的时间长度。由此可知,占空比就是高电平的时间长度和完整脉冲波长时间长度比值。通常,脉冲周期的时间长度不变,在需要调节显示面板110的亮度时,通过调整高电平的持续时间,生成的占空比随着改变,相应的时钟信号也发生改变。在需要调节显示亮度时,只要改变时钟信号的脉冲宽度就可以完成。
进而可知,时钟信号的占空比随着环境亮度的变化而变化。在环境亮度和显示面板110的亮度差异较大时,或者是,在环境亮度和显示面板110的亮度差异较小时,可以通过生成的时钟信号来控制精细程度,进而短时间内达到需要调整的亮度。
例如,在环境亮度和显示面板110的亮度差异较大时,提高占空比,从而尽快使显示面板110的亮度和环境亮度符合,保证用户能够看清显示画面。或者是,尽快降低显示面板110的亮度,避免显示面板110的亮度过亮,刺痛人眼。
在环境亮度和显示面板110的亮度差异较小时,通过降低占空比,减小供电电压的调整跨度,使用户能够找到显示面板110与环境亮度相适应的显示亮度,不至于出现过度调节,导致跨过了比较适合的显示亮度。
参阅图8,为了能够更加灵活的调整显示面板110的亮度,依据时钟信号在阶跃电压的基础上确定供电电压的步骤,包括:
步骤S310,选取阶跃电压作为基准电压,将占空比与基准电压相乘生成供电电压。阶跃电压乘以占空比,相当于乘以一个小数,从而使阶跃电压进一步减小,实现小于阶跃电压的调整。如电压产生单元131可以输出n个相差0.1V的阶跃电压,选择其中一个作为基准电压,占空比乘以这个基准电压就是供电电压。
通常,脉冲周期的时间长度不变,在需要调节显示面板110的亮度时,通过调整高电平的持续时间,生成的占空比随着改变,相应的时钟信号也发生改变。在需要调节显示亮度时,只要改变时钟信号的脉冲宽度就可以完成。
参阅图2和图9所示,依据时钟信号在阶跃电压的基础上确定供电电压的步骤之后,包括:
步骤S40,选取邻近基准电压的另一阶跃电压作为叠加电压;为了提高画面亮度,可以在短时间内前后施加两个电压,人眼看去是两个光亮叠加在一起。
步骤S50,在时钟信号的脉冲周期小于或等于预设阈值时,预设阈值为1毫秒,1毫秒内人眼无法识别。在高电平时将供电电压提供至供电端,在低电平时将叠加电压提供至供电端。
参阅图10所示,电压选择单元132根据时序控制模块120的选择指令信号Step,输出相邻的m和m-1两个阶跃电压,n≥m≥2,到达电压转化单元后,根据时钟信号CLK波形,当CLK为高准位H时输出第m阶跃电压,当CLK为低准位L时输出第m-1阶跃电压。光强是一种累积效果,CLK频率大于1KHz,即小于1毫秒,人眼完全不会感觉到CLK切换的闪烁,人眼感觉到的光强是m-1的阶跃电压加上0.1V*(CLK H的时间/CLK的周期时间)电压做为供电电压时的发光强度,以此实现光强的细腻化补偿。其中,3.3V时钟信号高电平,0V时钟信号低电平,在高电平输出(OUT)Step m阶跃电压,在低电平输出(OUT)Step m-1阶跃电压。
虽然已参照几个典型实施方式描述了本申请,但应当理解,所用的术语是说明和示例性、而非限制性的术语。由于本申请能够以多种形式具体实施而不脱离发明的精神或实质,所以应当理解,上述实施方式不限于任何前述的细节,而应在随附权利要求所限定的精神和范围内广泛地解释,因此落入权利要求或其等效范围内的全部变化和改型都应为随附权利要求所涵盖。
