Description

一种阵列基板及液晶显示装置  Array substrate and liquid crystal display device
【技术领域】[Technical Field]
本发明涉及液晶显示技术领域，特别是涉及一种阵列基板及液晶显示装置。 The present invention relates to the field of liquid crystal display technology, and in particular to an array substrate and a liquid crystal display device.
【背景技术】 【Background technique】
液晶显示面板的广视角是衡量液晶显示面板好坏的一项重要指标，在一些可视角度较小的液晶显示面板中，在正面能观看到质量较好的画面，画面的色彩度、对比度等都显示正常，但是在侧面观看时画面则会失色，对比度和颜色差异表现差。因此，有必要提高液晶显示面板的可视角度，使液晶显示面板具有更好的广视角效果。The wide viewing angle of the liquid crystal display panel is an important indicator for measuring the quality of the liquid crystal display panel. In some liquid crystal display panels with small viewing angles, the screen with good quality can be viewed on the front side, and the color degree and contrast of the screen can be observed. Both display normal, but the picture will be discolored when viewed from the side, and the contrast and color differences will be poor. Therefore, it is necessary to increase the viewing angle of the liquid crystal display panel, so that the liquid crystal display panel has a better wide viewing angle effect.
现有技术中，一般是通过2G1D（2 Gate 1 Date）的广视角技术来实现液晶显示面板的广视角效果。参考图1，在2G1D的像素设计中，每个像素单元10包括两条扫描线，分别是第一扫描线101和第二扫描线102，一条数据线103，还包括第一薄膜晶体管104和第二薄膜晶体管105。每个像素单元10划分为两个区域，分别对应为主像素电极106所在的区域和次像素电极107所在的区域。其中，第一扫描线101与第一薄膜晶体管104的栅极连接，数据线103与第一薄膜晶体管104的源极连接，主像素电极106与第一薄膜晶体管104的漏极连接；第二扫描线102与第二薄膜晶体管105的栅极连接，数据线103与第二薄膜晶体管105的源极连接，次像素电极107与第二薄膜晶体管105的漏极连接。In the prior art, generally through 2G1D (2 Gate 1 Date) wide viewing angle technology to achieve a wide viewing angle effect of the liquid crystal display panel. Referring to FIG. 1, in the pixel design of 2G1D, each pixel unit 10 includes two scan lines, which are a first scan line 101 and a second scan line 102, and a data line 103, further including a first thin film transistor 104 and a first Two thin film transistors 105. Each of the pixel units 10 is divided into two regions, which respectively correspond to a region where the main pixel electrode 106 is located and a region where the sub-pixel electrode 107 is located. The first scan line 101 is connected to the gate of the first thin film transistor 104, the data line 103 is connected to the source of the first thin film transistor 104, and the main pixel electrode 106 is connected to the drain of the first thin film transistor 104. The second scan The line 102 is connected to the gate of the second thin film transistor 105, the data line 103 is connected to the source of the second thin film transistor 105, and the sub-pixel electrode 107 is connected to the drain of the second thin film transistor 105.
主像素电极106通过第一薄膜晶体管104与第一扫描线101和数据线103连接，次像素电极107通过第二薄膜晶体管105与第二扫描线102和数据线103连接。在对像素单元10输入驱动信号以实现广视角效果时，第一扫描线101输入扫描信号以控制第一薄膜晶体管104导通，数据线103输入相应的电压信号至主像素电极106，随后停止第一扫描线101输入扫描信号，并使第二扫描线102输入扫描信号以控制第二薄膜晶体管105导通，数据线103输入相应的电压信号至次像素电极。通过第一扫描线101和第二扫描线102的作用，使得数据线能够分别输入不同的数据信号至主像素电极106和次像素电极107，从而使主像素电极106和次像素电极107形成电压差，进而达到广视角效果。The main pixel electrode 106 is connected to the first scan line 101 and the data line 103 through the first thin film transistor 104, and the sub-pixel electrode 107 is connected to the second scan line 102 and the data line 103 through the second thin film transistor 105. When a driving signal is input to the pixel unit 10 to achieve a wide viewing angle effect, the first scanning line 101 inputs a scanning signal to control the first thin film transistor 104 to be turned on, and the data line 103 inputs a corresponding voltage signal to the main pixel electrode 106, and then stops the first A scan line 101 inputs a scan signal, and the second scan line 102 inputs a scan signal to control the second thin film transistor 105 to be turned on, and the data line 103 inputs a corresponding voltage signal to the sub-pixel electrode. By the action of the first scan line 101 and the second scan line 102, the data lines can respectively input different data signals to the main pixel electrode 106 and the sub-pixel electrode 107, thereby causing the main pixel electrode 106 and the sub-pixel electrode 107 to form a voltage difference. In order to achieve a wide viewing angle effect.
在上述方式中，通过第一扫描线101和第二扫描线102的控制作用，虽然能够控制主像素电极106和次像素电极107形成电压差以达到广视角效果，但是必须使用两条扫描线进行单独控制，增加了扫描驱动芯片的使用量，不利于成本的降低。In the above manner, by controlling the first scanning line 101 and the second scanning line 102, although the voltage difference between the main pixel electrode 106 and the sub-pixel electrode 107 can be controlled to achieve a wide viewing angle effect, it is necessary to use two scanning lines. Separate control increases the usage of the scan driver chip, which is not conducive to cost reduction.

本实施方式，通过控制元件205来控制次像素开关204的导通和关闭，以使得数据线30能够分别对主像素电极201和次像素电极202输入不同电压信号，进而使主像素电极201和次像素电极202形成电压差而达到广视角效果。具体地，控制元件205用于扫描线40输入扫描信号以导通主像素开关203的同时，导通次像素开关204，并且控制次像素开关204在主像素开关203由导通转为关闭之后仍然维持导通状态。进一步而言，扫描线40输入扫描信号后，扫描信号被同时输入主像素开关203的控制端G1和控制元件205的输入端S3，主像素开关203导通，此时数据线30通过主像素开关203输入主像素电极201所需的电压信号至主像素电极201。扫描信号通过控制元件205输入至次像素开关204的控制端G2以导通次像素开关204，虽然数据线30输入的主像素电极201的电压信号也会进入到次像素电极202，但是由于人眼的反应时间较慢而不易察觉到。在完成主像素电极201的驱动后，扫描线40停止输入扫描信号，主像素开关203关闭，此时控制元件205控制次像素开关204仍然维持导通状态，进而数据线30能够输入次像素电极202所需的电压信号至次像素电极202，以此完成次像素电极202的驱动。In this embodiment, the conduction and the closing of the sub-pixel switch 204 are controlled by the control element 205, so that the data line 30 can input different voltage signals to the main pixel electrode 201 and the sub-pixel electrode 202, respectively, thereby causing the main pixel electrode 201 and the second. The pixel electrode 202 forms a voltage difference to achieve a wide viewing angle effect. Specifically, the control element 205 is used to turn on the sub-pixel switch 204 while the scan line 40 inputs the scan signal to turn on the main pixel switch 203, and controls the sub-pixel switch 204 to remain after the main pixel switch 203 is turned from off to off. Maintain the conduction state. Further, after the scan line 40 inputs the scan signal, the scan signal is simultaneously input to the control terminal G1 of the main pixel switch 203 and the input terminal S3 of the control element 205, and the main pixel switch 203 is turned on. At this time, the data line 30 passes through the main pixel switch. 203 inputs a voltage signal required for the main pixel electrode 201 to the main pixel electrode 201. The scan signal is input to the control terminal G2 of the sub-pixel switch 204 through the control element 205 to turn on the sub-pixel switch 204, although the voltage signal of the main pixel electrode 201 input by the data line 30 also enters the sub-pixel electrode 202, but due to the human eye. The reaction time is slow and not easy to detect. After the driving of the main pixel electrode 201 is completed, the scan line 40 stops inputting the scan signal, and the main pixel switch 203 is turned off. At this time, the control element 205 controls the sub-pixel switch 204 to remain in the on state, and the data line 30 can be input to the sub-pixel electrode 202. The required voltage signal is applied to the sub-pixel electrode 202, thereby completing the driving of the sub-pixel electrode 202.
本实施方式的控制元件205是包括定时器和储能元件的器件，在扫描线40输入扫描信号时，扫描信号通过控制元件205而导通次像素开关204，并且控制元件205的储能器件开始存储能量，在扫描线40停止输入扫描信号后，储能器件释放其能量而使得次像素开关204的控制端G2能够继续获得扫描信号而保持导通状态，而通过定时器的定时作用控制储能器件在达到预定时间后停止释放能量，进而控制次像素开关204在预定时间后关闭。The control element 205 of the present embodiment is a device including a timer and an energy storage element. When the scan line 40 inputs a scan signal, the scan signal passes through the control element 205 to turn on the sub-pixel switch 204, and the energy storage device of the control element 205 begins. The energy is stored. After the scan line 40 stops inputting the scan signal, the energy storage device releases its energy, so that the control terminal G2 of the sub-pixel switch 204 can continue to obtain the scan signal to maintain the on state, and the energy storage is controlled by the timing action of the timer. The device stops releasing energy after reaching a predetermined time, thereby controlling the sub-pixel switch 204 to turn off after a predetermined time.
此外，在另一实施方式中，也可以通过定时器的定时作用使得控制元件205在扫描线40输入扫描信号以导通主像素开关203的预定时间之后，再导通次像素开关204。In addition, in another embodiment, the timing element of the timer may be used to cause the control element 205 to turn on the sub-pixel switch 204 after the scan line 40 inputs the scan signal to turn on the main pixel switch 203 for a predetermined time.
通过上述方式，在控制元件205的作用下，主像素开关203关闭后次像素开关204仍然为导通状态，使得主像素开关203和次像素开关204导通的时间不相同，从而数据线30在主像素开关203和次像素开关204相应的导通时间内分别对主像素电极201和次像素电极202输入电压信号，进而能控制主像素电极201和次像素电极202所输入的电压信号不相同，使得主像素电极201和次像素电极202形成电压差而达到广视角效果。此外，本实施方式只需使用一条扫描线40和一条数据线30共同驱动主像素电极201和次像素电极202而达到广视角效果，减少了扫描线40的用量，进而减少扫描驱动芯片的使用量，有利于降低成本。In the above manner, under the action of the control element 205, the main pixel switch 203 is turned off and the sub-pixel switch 204 is still in an on state, so that the main pixel switch 203 and the sub-pixel switch 204 are turned on for different times, so that the data line 30 is The main pixel switch 203 and the sub-pixel switch 204 respectively input voltage signals to the main pixel electrode 201 and the sub-pixel electrode 202 during the respective on-times, thereby controlling the voltage signals input by the main pixel electrode 201 and the sub-pixel electrode 202 to be different. The main pixel electrode 201 and the sub-pixel electrode 202 are caused to form a voltage difference to achieve a wide viewing angle effect. In addition, the present embodiment only needs to use one scan line 40 and one data line 30 to jointly drive the main pixel electrode 201 and the sub-pixel electrode 202 to achieve a wide viewing angle effect, reducing the amount of the scan line 40, thereby reducing the usage of the scan driver chip. It is beneficial to reduce costs.
当然，控制元件205还可以是仅仅包括储能元件的器件，或者是具备钳制电压功能的器件，在扫描线40停止输入扫描信号后，仍然使输出端保持在钳制电压，进而使次像素开关204维持在导通状态。Of course, the control component 205 may also be a device including only the energy storage component, or a device having a clamp voltage function. After the scan line 40 stops inputting the scan signal, the output terminal is still maintained at the clamp voltage, thereby enabling the sub-pixel switch 204. Maintained in a conducting state.
对应于控制元件为具备钳制电压功能的器件的实施方式中，如图3，控制元件505还包括控制端G3，其控制端G3连接下一行扫描线80，用于在扫描线80输入扫描信号时关闭次像素开关504。In an embodiment in which the control element is a device having a clamp voltage function, as shown in FIG. 3, the control element 505 further includes a control terminal G3, and the control terminal G3 is connected to the next row of scan lines 80 for inputting the scan signal when the scan line 80 is input. The sub-pixel switch 504 is turned off.
进一步参阅图4，图4是图3的阵列基板的具体实现方式的结构示意图。控制元件505包括第一开关5051和第二开关5052。其中，第一开关5051包括控制端G4、输入端S4以及输出端D4，第二开关5052包括控制端G5、输入端S5以及输出端D5。第一开关5051的控制端G4和输入端S4相连接，并作为控制元件505的输入端S3与主像素开关503的控制端G1一同连接同一条扫描线70，第一开关5051的输出端D4作为控制元件505的输出端D3连接次像素开关504的控制端G2。第二开关5052的输出端D5连接第一开关5051的输出端D4，第二开关5052的输入端S5连接第一开关5051的输入端S4，第二开关5052的控制端G5作为控制元件505的控制端G3连接下一行扫描线80。Referring to FIG. 4, FIG. 4 is a schematic structural diagram of a specific implementation of the array substrate of FIG. Control element 505 includes a first switch 5051 and a second switch 5052. The first switch 5051 includes a control terminal G4, an input terminal S4, and an output terminal D4. The second switch 5052 includes a control terminal G5, an input terminal S5, and an output terminal D5. The control terminal G4 of the first switch 5051 is connected to the input terminal S4, and the input terminal S3 of the control element 505 is connected to the same scanning line 70 together with the control terminal G1 of the main pixel switch 503, and the output terminal D4 of the first switch 5051 is used as The output D3 of the control element 505 is coupled to the control terminal G2 of the sub-pixel switch 504. The output terminal D5 of the second switch 5052 is connected to the output terminal D4 of the first switch 5051, the input terminal S5 of the second switch 5052 is connected to the input terminal S4 of the first switch 5051, and the control terminal G5 of the second switch 5052 is controlled by the control element 505. The terminal G3 is connected to the next line of scanning lines 80.
通过下一行扫描线80、第一开关5051和第二开关5052的相互作用以控制次像素开关504的导通和关闭，能够实现主像素开关503和次像素开关504在不同的时间内导通，进而使主像素电极501和次像素电极502能够形成电压差。具体地，请一并参阅图5所示的信号波形图，本实施方式的扫描信号为高电平脉冲信号。扫描线70输入高电平信号以控制主像素开关503和第一开关5051导通，而第一开关5051的输入端S4也与扫描线70连接，使得在第一开关5051导通后高电平信号从第一开关5051的输入端S4输入，并通过输出端D4输出至次像素开关504的控制端G2，以导通次像素开关504。主像素开关503导通后，在t1时间内数据线对主像素电极501输入所需的电压信号。虽然在t1时间内虽然主像素电极501的电压信号也会输入至次像素电极502，但是由于人眼的反应时间较慢，因此不易察觉到。完成主像素电极501所需的电压信号输入后，扫描线70停止输入高电平信号，此时由于第一开关5051的控制端G4和输入端S4相连接，使得控制元件505的输入端S3还维持着高电平信号，进而使得次像素开关504的控制端G2在t2的时间内仍然有高电平信号输入，以使次像素开关504保持导通状态。在t2的时间内，主像素开关503关闭而次像素开关504导通，数据线60对次像素电极502输入所需的电压信号。因此，由于主像素开关503和次像素开关504所导通的时间不相同，能够在t1时间内和t2时间内分别对主像素电极501和次像素电极502输入不同的电压信号以使主像素电极501和次像素电极502形成电压差，进而控制主像素电极501所在的区域和次像素电极502所在的区域的液晶分子偏转角度不相同，达到广视角效果。Through the interaction of the next row of scan lines 80, the first switch 5051 and the second switch 5052 to control the turn-on and turn-off of the sub-pixel switch 504, the main pixel switch 503 and the sub-pixel switch 504 can be turned on at different times. Further, the main pixel electrode 501 and the sub-pixel electrode 502 can form a voltage difference. Specifically, referring to the signal waveform diagram shown in FIG. 5, the scan signal of the present embodiment is a high-level pulse signal. The scan line 70 inputs a high level signal to control the main pixel switch 503 and the first switch 5051 to be turned on, and the input terminal S4 of the first switch 5051 is also connected to the scan line 70, so that the first switch 5051 is turned on after the high level. The signal is input from the input terminal S4 of the first switch 5051 and output to the control terminal G2 of the sub-pixel switch 504 through the output terminal D4 to turn on the sub-pixel switch 504. After the main pixel switch 503 is turned on, the data line inputs a desired voltage signal to the main pixel electrode 501 during the time t1. Although the voltage signal of the main pixel electrode 501 is input to the sub-pixel electrode 502 during the time t1, since the reaction time of the human eye is slow, it is not easily noticeable. After the voltage signal input required by the main pixel electrode 501 is input, the scan line 70 stops inputting a high level signal. At this time, since the control terminal G4 of the first switch 5051 and the input terminal S4 are connected, the input terminal S3 of the control element 505 is further The high level signal is maintained, so that the control terminal G2 of the sub-pixel switch 504 still has a high level signal input during the time t2, so that the sub-pixel switch 504 remains in the on state. During the time t2, the main pixel switch 503 is turned off and the sub-pixel switch 504 is turned on, and the data line 60 inputs a desired voltage signal to the sub-pixel electrode 502. Therefore, since the times at which the main pixel switch 503 and the sub-pixel switch 504 are turned on are different, different voltage signals can be input to the main pixel electrode 501 and the sub-pixel electrode 502 in the time t1 and the time t2, respectively, so that the main pixel electrode 501 and the sub-pixel electrode 502 form a voltage difference, thereby controlling the liquid crystal molecules in the region where the main pixel electrode 501 is located and the region in which the sub-pixel electrode 502 is located to have different deflection angles, thereby achieving a wide viewing angle effect.
在数据线60对次像素电极502输入所需的电压信号之后，开始下一行像素单元的扫描。此时，下一行扫描线80输入高电平信号，第二开关5052导通，而由于第二开关5052的输入端S5、输出端D5分别和第一开关5051的输入端S3、输出端D3连接，在第二开关5052导通时，第一开关5051的输入端S3、输出端D4和第二开关5052的输入端S5、输出端D5形成回路，使得第一开关5051的输入端S3的高电平信号被拉低，从而次像素开关504的控制端G2没有高电平信号输入，次像素开关504关闭。After the data line 60 inputs the desired voltage signal to the sub-pixel electrode 502, scanning of the next row of pixel cells begins. At this time, the next line scan line 80 inputs a high level signal, and the second switch 5052 is turned on, and the input end S5 and the output end D5 of the second switch 5052 are respectively connected to the input end S3 and the output end D3 of the first switch 5051. When the second switch 5052 is turned on, the input terminal S3 of the first switch 5051, the output terminal D4, and the input terminal S5 and the output terminal D5 of the second switch 5052 form a loop, so that the input terminal S3 of the first switch 5051 is powered. The flat signal is pulled low so that the control terminal G2 of the sub-pixel switch 504 has no high level signal input and the sub-pixel switch 504 is turned off.
因此，对于次像素开关504而言，当扫描线70输入扫描信号时，第一开关5051控制次像素开关504导通，并且在扫描线70停止输入扫描信号之后并在下一行扫描线80输入扫描信号之前，控制次像素开关504仍然保持导通状态，进而使得数据线60能够分别对主像素电极501和次像素电极502输入不同的电压信号。当扫描线80输入扫描信号时，第二开关5052控制次像素关闭，由此完成像素单元50的驱动。Therefore, for the sub-pixel switch 504, when the scan line 70 inputs the scan signal, the first switch 5051 controls the sub-pixel switch 504 to be turned on, and after the scan line 70 stops inputting the scan signal and inputs the scan signal on the next-line scan line 80. Previously, the control sub-pixel switch 504 remains in an on state, thereby enabling the data line 60 to input different voltage signals to the main pixel electrode 501 and the sub-pixel electrode 502, respectively. When the scan line 80 inputs the scan signal, the second switch 5052 controls the sub-pixel to be turned off, thereby completing the driving of the pixel unit 50.

The output corresponds to the drain of the thin film transistor.

此外，本实施方式的阵列基板还包括对应不透光区域的暗区100，该暗区100的至少一部分设置于像素单元之间。为了提高开口率，扫描线70、主像素开关503、次像素开关504以及控制元件505均布局于像素单元之间，如图4所示一样，扫描线70、主像素开关503和第一开关5051布局于像素单元50和上一像素单元（图未示）之间，而次像素电极504和第二开关5052布局于像素单元50和下一像素单元90之间。In addition, the array substrate of the present embodiment further includes a dark region 100 corresponding to the opaque region, and at least a portion of the dark region 100 is disposed between the pixel units. In order to increase the aperture ratio, the scan line 70, the main pixel switch 503, the sub-pixel switch 504, and the control element 505 are all disposed between the pixel units, as shown in FIG. 4, the scan line 70, the main pixel switch 503, and the first switch 5051. The pixel pixel 50 and the previous pixel unit (not shown) are disposed between the pixel unit 50 and the second pixel unit 90.
本实施方式，通过第一开关5051、第二开关5052以及下一行扫描线80的共同作用下相应控制次像素开关504导通和关闭，从而使得主像素开关503和次像素开关504在不同的时间内导通，进而使数据线60能够分别对主像素电极501和次像素电极502输入不同的电压信号，以达成广视角效果，并且一个像素单元50对应一条扫描线70和一条数据线60，即可完成对主像素电极501和次像素电极502的不同时驱动进而达到广视角效果，减少了扫描线的使用量，有利于降低成本，同时也能提高开口率。In this embodiment, the sub-pixel switch 504 is controlled to be turned on and off by the cooperation of the first switch 5051, the second switch 5052, and the next scan line 80, so that the main pixel switch 503 and the sub-pixel switch 504 are at different times. The internal conduction enables the data line 60 to input different voltage signals to the main pixel electrode 501 and the sub-pixel electrode 502, respectively, to achieve a wide viewing angle effect, and one pixel unit 50 corresponds to one scanning line 70 and one data line 60, that is, The different time driving of the main pixel electrode 501 and the sub-pixel electrode 502 can be completed to achieve a wide viewing angle effect, the use amount of the scanning line is reduced, the cost is reduced, and the aperture ratio can be improved.
