本实施例的处理后的显示信号不仅包括背光动态调节信号,还至少包括用于驱动显示区106的显示驱动信号及显示数据信号。
计算机在表示图像的时候是用8bit(256)级或16bit(65536)级来区分图像的亮度的,但这仅仅几百或几万个亮度级别很难再现真实自然的光照情况。目前普通的图片都是由三原色—红、绿、蓝组成的,这是针对阴极射线显像管显示器显示的图像而制定的规范,通过这三种颜色的组合,任何颜色都可以在屏幕上显示出来,颜色的强度等级在256个灰度单位以内,也就是说,普通的图像每个像素只有0-255的灰度范围,自然界的光线颜色和强度是上述的规格无法囊括的,例如,一些极亮和极暗的光线不能通过上述的规格来表现。为解决上述问题,本实施例显示组件101通过背光驱动电路105动态调节背光,能够扩大图像的灰度范围,从而能够提高图像显示的显示效果。
在整个显示器的生产过程中,显示组件101与主机108往往由不同的厂商生产,若将显示组件101的部分组件,例如背光驱动电路105,设置在主机108侧的话,会制约整个显示器的生产效率,因为不同的厂商具有不同的生产规则,生产出的产品规则也会存在差异,这样会增加显示组件101与主机108的组装及调试等工作的难度。
本实施例的显示驱动电路104与背光驱动电路105设置于显示区106靠近主机108的同一侧外。当然,在其它实施例中,显示驱动电路104与背光驱动电路105可设置于显示区106的不同侧外。针对直下式背光组件109,还可以将显示驱动电路104与背光驱动电路105进行分层设置。
区别于现有技术,本实施例显示组件101通过设置于柔性电路板103上的背光驱动电路105在显示驱动电路104中获得背光动态调节信号,以驱动显示面板102的背光组件109,从而实现背光的动态调节;且将背光驱动电路105设置于柔性电路板103上,以将背光驱动电路105与主机108分开设置,能减少因主机108生产厂商与显示组件101生产厂商不同,而导致二者在生产、组装调试中的出现相互制约的问题,从而能够提高显示组件101的生产效率。
可选地,本实施例显示组件101的背光动态调节信号是内容对应背光控制(Content Adaptive
Brightness Control,CABC)信号格式的脉冲宽度调制(Pulse Width
Modulation,PWM)信号。当然,在其它实施例中,可以采用环境光侦测对应背光控制(LABC ,Light Adaptive Brightness
Control)信号格式等来代替CABC信号格式,还可以采用可控硅调光方式来替代PWM调光方式。
可选地,本实施例背光组件109被定义为多个发光分区110,每个发光分区110对应于显示区106的不同区域,背光动态调节信号用于单独调节发光分区110的发光或不发光,或者发光的强弱,以丰富背光亮度,从而扩大图像的灰度范围。
可选地,本实施例的柔性电路板103设置有第一信号传输线111、第二信号传输线112、背光驱动线113以及背光驱动接口114;第一信号传输线111从连接主机108的一端延伸至连接显示面板102的一端,直至连接显示驱动电路104,用于传输显示信号;第二信号传输线112从连接显示面板102的一端延伸至设置于柔性电路板103的背光驱动电路105。且数量等于发光分区110的数量,与发光分区110一一对应连接,用于传输背光动态调节信号;背光驱动线113从背光驱动电路105延伸至背光驱动接口114,背光驱动接口114用于与背光组件109接插。
本实施例中,第二信号传输线113与背光驱动接口114数量相同,采用并行方式传输背光动态调节信号。当然,在其它实施例中,可以采用一根第二信号传输线113采用串联的方式传输背光动态调节信号给所有背光驱动接口114,当然,还可以采用部分串联、部分并联的方式实现背光动态调节信号的传输。
可选地,请参阅图2,图2是本申请显示组件的柔性电路板的一实施例的结构示意图。本实施例柔性电路板201包括相连的元器件承载部202以及连接部203,连接部203一端连接组件安装区204,连接部203的另一端连接元器件承载部202一端,元器件承载部202另一端用于连接主机205;背光驱动电路206设置于元器件承载部202。
在一个应用场景中,本实施例的柔性电路板201的承载部202为T型结构,这种T型承载部202只需设置一信号传输线(图未示),将主机205的显示信号传输给显示驱动电路(图未示),可以将背光驱动电路206通过连接部203与显示驱动电路连接,而无需在背光驱动电路20与显示驱动电路间设置其它传输线,以减少柔性电路板201面积,简化柔性电路板201的结构。
本申请进一步提供另一实施例的显示组件,本实施例所揭示的显示组件在上述实施例的显示组件的基础上进行描述。请参阅图3,图3是本申请显示组件第二实施例的结构示意图。本实施例显示组件301将显示驱动电路302设置在柔性电路板303上,可以减少组件安装区304的尺寸。当然,在其它实施例中,还可以将显示驱动电路302设置在柔性电路板303上,而将背光驱动电路305设置在组件安装区304上,或者将二者都设置在组件安装区304上。
请参阅图4,图4是申请用于显示设备的电路组件第一实施例的结构示意图。本实施例电路组件401包括柔性电路板402及背光驱动电路403,柔性电路板402的一端固定于显示面板404(参阅图1),另一端用于连接主机405,以输入显示信号至驱动显示面板404的显示驱动电路406;背光驱动电路403设置于柔性电路板402上,用于从显示驱动电路406中获得背光动态调节信号并处理,以处理后的背光动态调节信号驱动显示面板404的背光组件407。从上述可知,本实施例电路组件401及显示面板404组成显示设备408,显示面板404用于显示从主机405中获取的显示信号,显示面板404进一步包括驱显示动电路406及背光组件407。
区别于现有技术,本实施例电路组件401通过设置于柔性电路板402上的背光驱动电路403在显示驱动电路406中获得背光动态调节信号,以驱动显示面板404的背光组件407,从而实现背光的动态调节;且将背光驱动电路403设置于柔性电路板402上,以将背光驱动电路403与主机405分开设置,能减少因主机405生产厂商与电路组件401生产厂商不同,而导致二者在生产、组装调试中的出现相互制约的问题,从而能够提高电路组件401整个显示设备(图未示)的生产效率。
可选地,本实施例电路组件401背光动态调节信号是内容对应背光控制(Content Adaptive
Brightness Control,CABC)信号格式的脉冲宽度调制(Pulse Width
Modulation,PWM)信号。当然,在其它实施例中,可以采用环境光侦测对应背光控制(LABC ,Light Adaptive Brightness
Control)信号格式等来代替CABC信号格式,还可以采用可控硅调光方式来替代PWM调光方式。
可选地,本实施例背光组件407被定义为多个发光分区(图未示,可参照图1),每个发光分区(图未示)对应于显示区的不同区域,背光动态调节信号用于单独调节发光分区的发光或不发光,或者发光的强弱,以丰富背光亮度,从而扩大图像的灰度范围。
本实施例的柔性电路板402的具体结构及工作原理已在上述实施例中进行了叙述,这不不赘述,且对电路组件401的扩展与对上述显示组件的扩展相似,这里不赘述。
以上所述仅为本申请的实施方式,并非因此限制本申请的专利范围,凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
