本申请涉及一种电压调节技术，特别涉及一种显示装置。
背景技术
显示器中，系统主板通过线路连接至控制板(Control Board，C-Board)，控制板通过如柔性扁平电缆(Flexible Flat Cable，FFC)连接印刷电路板(PCB)，印刷电路板再通过源极覆晶薄膜(Source-Chip on Film，S-COF)和栅极覆晶薄膜(Gate-Chip on Film，G-COF)与显示区连接。显示器驱动方式包括：系统主板将颜色(例如：R/G/B)压缩信号、控制信号及电源传输至控制板。信号经过时序装置(Timing Controller，TCON)处理后，传输至源极驱动电路(Source Driver)及栅极驱动电路(Gate Driver)。通过相关的集成电路或芯片将必要性的数据与电源传输于显示区，从而使得显示器获得呈现画面需求的电源、信号。
由于产品会有品质误差，一般会进行老化检测来排除故障品，以“浴缸曲线”(Bathtub curve,又称失效率曲线或U型曲线)示意，故障阶段分为：早期故障期，偶然故障期，严重故障期。然而，产品一般成品后就会直接出货到相应供应商，故较不易卡控这样的早期故障期的不良产品。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。

具体实施方式
以下各实施例的说明是参考附加的图式，用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本申请，而非用以限制本申请。
附图和说明被认为在本质上是示出性的，而不是限制性的。在图中，结构相似的装置是以相同标号表示。另外，为了理解和便于描述，附图中示出的每个组件的尺寸和厚度是任意示出的，但是本申请不限于此。
在附图中，为了清晰起见，夸大了层、膜、面板、区域等的厚度，亦夸大电路的配置范围。在附图中，为了理解和便于描述，夸大了一些层和区域的厚度，亦夸大电路的配置范围。将理解的是，当例如层、膜、区域、电路或基底的组件被称作“在”另一组件“上”时，所述组件可以直接在所述另一组件上，或者也可以存在中间组件。
另外，在说明书中，除非明确地描述为相反的，否则词语“包括”将被理解为意指包括所述组件，但是不排除任何其它组件。此外，在说明书中，“在......上”意指位于目标组件上方或者下方，而不意指必须位于基于重力方向的顶部上。
为更进一步阐述本申请为达成预定目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本申请提出的一种显示装置，其具体实施方式、结构、特征及其功效，详细说明如后。
图1为范例性的显示装置的架构示意图。一种显示装置，包括：控制板100，所述控制板100包括时序装置(Timing Controller，TCON)101；印刷电路板103，与所述控制板之间通过柔性扁平电缆(Flexible Flat Cable，FFC)102相连接；源极驱动电路104与栅极驱动电路105分别与显示区106内的数据线及扫描线连接。在一些实施例中，栅极驱动电路105及源极驱动电路104包括但不限制为覆晶薄膜形式。在一些实施例中，栅极驱动装置105包括但不限于栅极阵列驱动(Gate On Array，GOA)形式，栅极驱动电路105可被分为升压模块(level shifter)及移位寄存器(shift register)，升压模块设置在控制板上，移位寄存器则是设置在主动阵列基板上。
显示装置的驱动方式包括：系统主板提供颜色(例如：R/G/B)压缩信号、控制信号及电源传输至控制板100。控制板100上的时序模块101于处理此等信号后，连同被驱动电路处理的电源，通过柔性扁平电缆(Flexible Flat Cable，FFC)102，一并传输至印刷电路板103的栅极驱动装置105及源极驱动装置104，栅极驱动装置105及源极驱动装置104将必要性的数据与电源传输于显示区106，从而使得显示装置获得呈现画面需求的电源、信号。
面板的打开是以逐线扫描(Line By Line)的方式把每一条数据线打开。具体实现方式为，栅极驱动装置105接受时序模块提供的时序信号(行信号)，每经过一个时钟的上升沿就产生出一个数字信号。而每一个数字信号对应一个输出。通过数模转换，将高低电平转换为主动开关需要的高低电压以形成栅极驱动信号，使面板逐行打开，再通过像素电极进行充电。
