技术领域technical field
本发明涉及显示技术领域，更具体地，涉及一种触控显示面板和触控显示装置。The present invention relates to the field of display technology, and more specifically, to a touch display panel and a touch display device.
背景技术Background technique
随着显示技术的发展，触控显示装置具有操作简单，趣味性强，受到消费者的青睐，带有触控功能的手机、电脑等显示装置已日渐普及。With the development of display technology, touch display devices are easy to operate and highly interesting, and are favored by consumers. Display devices such as mobile phones and computers with touch functions have become increasingly popular.
现有技术提供的一种触控显示装置中，在显示面板制作完成后，将一块触控基板与显示面板贴合，触控基板用于实现触控功能。请参考图1，图1是现有技术提供的一种触控基板的结构示意图。触控基板包括衬底基板01、设置在衬底基板01上的触控电极02和触控线03，触控线03与对应的触控电极02电连接，为触控电极02传输电信号。由于显示面板和触控基板是分开制作而后贴合的，因此，对于显示面板和触控基板的配合的精度要求较高。显示面板中设置有黑矩阵，在触控显示装置的出光方向上，黑矩阵需要覆盖触控线03。如果黑矩阵和触控线03的对位偏差较大，会影响显示效果、降低触控显示装置的良率。除此之外，触控电极02为块状，覆盖显示面板的显示区，会降低显示面板的透光率。In a touch display device provided in the prior art, after the display panel is manufactured, a touch substrate is attached to the display panel, and the touch substrate is used to realize the touch function. Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of a touch substrate provided in the prior art. The touch control substrate includes a base substrate 01 , touch electrodes 02 disposed on the base substrate 01 , and touch wires 03 . The touch wires 03 are electrically connected to corresponding touch electrodes 02 to transmit electrical signals to the touch electrodes 02 . Since the display panel and the touch substrate are manufactured separately and then bonded together, the precision of matching between the display panel and the touch substrate is high. A black matrix is arranged in the display panel, and the black matrix needs to cover the touch line 03 in the light emitting direction of the touch display device. If the alignment deviation between the black matrix and the touch line 03 is large, it will affect the display effect and reduce the yield of the touch display device. In addition, the touch electrodes 02 are block-shaped and cover the display area of the display panel, which reduces the light transmittance of the display panel.

The base substrate 10 is used to carry a black matrix 20 , a touch function layer 30 and a thin film transistor array layer 40 .
黑矩阵(Black Matrix，简称BM)用于遮挡触控显示面板中的反光、防止触控显示面板漏光，并且，黑矩阵可以增加显示面板的色彩的对比度。A black matrix (Black Matrix, BM for short) is used to block reflection in the touch display panel and prevent light leakage from the touch display panel, and the black matrix can increase the color contrast of the display panel.
薄膜晶体管阵列层40中包括阵列设置的薄膜晶体管(Thin Film Transistor，简称TFT)(图中未示意出)，已知的，薄膜晶体管包括栅极、源极和漏极。薄膜晶体管与栅极线41电连接，薄膜晶体管的源极和数据线42电连接，薄膜晶体管的漏极与像素电极(图中未示意出)电连接。薄膜晶体管阵列层40中还包括多条栅极线41和多条数据线42，多条栅极线41和多条数据线42交叉绝缘限定出子像素区401。子像素区401部分被黑矩阵20覆盖，子像素区401中没有被黑矩阵20覆盖的区域为透光区4011。换言之，在垂直于衬底基板10的方向上，透光区4011与黑矩阵20不交叠。The thin film transistor array layer 40 includes thin film transistors (Thin Film Transistor, TFT for short) arranged in an array (not shown in the figure). As known, a thin film transistor includes a gate, a source and a drain. The thin film transistor is electrically connected to the gate line 41 , the source of the thin film transistor is electrically connected to the data line 42 , and the drain of the thin film transistor is electrically connected to the pixel electrode (not shown in the figure).

触控功能层30包括网格状的触控电极31，本实施例对触控电极31的形状、大小、数量均不作具体限制。触控电极31使用导电材料制作，可以接收电信号。触控电极31的工作模式可以为自电容式、也可以为互电容式，本实施例对此不作具体限制。在垂直于衬底基板10的方向上，黑矩阵20覆盖触控电极31，由于黑矩阵20与触控电极31设置在同一块衬底基板10上，对准偏差小、对位精度较高。触控电极31与透光区4011不交叠，不会影响显示面板的透光率。The touch function layer 30 includes grid-shaped touch electrodes 31 , and the shape, size, and quantity of the touch electrodes 31 are not specifically limited in this embodiment. The touch electrodes 31 are made of conductive materials and can receive electrical signals. The working mode of the touch electrodes 31 may be self-capacitance or mutual capacitance, which is not specifically limited in this embodiment.

The display panel provided by the embodiment of the present invention does not emit light by itself, and needs an external light source. The side where the light source enters the touch display panel is the light input side; the side where the light passes through the touch display panel is the light output side, and the light output side is also the side where the user observes the touch display panel. Since the black matrix, the touch function layer and the thin film transistor array layer are all arranged on one side of the base substrate, the alignment accuracy is high, and the side of the base substrate 10 away from the black matrix 20 can be set as the light output side or the light input side.
本发明实施例提供的触控显示面板中，触控功能层集成在显示面板内部，无需额外提供触控基板，简化了触控显示面板的制造工艺。并且，触控功能层与黑矩阵设置在同一块衬底基板上，对准偏差小、对位精度较高。触控功能层包括网格状的触控电极，在垂直于衬底基板的方向上，触控电极与子像素区的透光区不交叠，不会影响显示面板的透光率。除此之外，本发明提供的触控显示面板包括相对设置的出光侧和入光侧，由于黑矩阵、触控功能层和薄膜晶体管阵列层均设置在衬底基板的一侧，对位精度较高，因此衬底基板背离黑矩阵的一侧可以设置为出光侧，也可以设置为入光侧。In the touch display panel provided by the embodiment of the present invention, the touch function layer is integrated inside the display panel, and no additional touch substrate is required, which simplifies the manufacturing process of the touch display panel. Moreover, the touch function layer and the black matrix are arranged on the same base substrate, so the alignment deviation is small and the alignment accuracy is high. The touch function layer includes grid-shaped touch electrodes. In the direction perpendicular to the base substrate, the touch electrodes do not overlap with the light-transmitting regions of the sub-pixel regions, which will not affect the light transmittance of the display panel. In addition, the touch display panel provided by the present invention includes a light-emitting side and a light-receiving side that are oppositely arranged. Since the black matrix, the touch function layer and the thin film transistor array layer are all arranged on one side of the base substrate, the alignment accuracy Higher, so the side of the base substrate away from the black matrix can be set as the light-emitting side, or it can be set as the light-incident side.
在一些可选的实施例中，触控电极的材料包括金属，例如钼、铝、钛或者包含钼、铝、钛的合金。现有技术中，制作触控显示面板中金属材质的栅极线、数据线等信号线的工艺非常成熟，使用金属材料制作触控电极，可以使用现有的成熟的工艺制作，无需研发额外的制造工艺，制作方法简单，且良率较高。In some optional embodiments, the material of the touch electrode includes metal, such as molybdenum, aluminum, titanium or an alloy containing molybdenum, aluminum, titanium.

可选的，本发明实施例提供的触控显示面板中，触控电极31的工作模式为互电容式，触控电极包括触控发射电极和触控接收电极。触控发射电极和触控接收电极分别接收电信号后，二者之间形成基础电容。当触控显示面板发生触控操作时，触控物体(例如手指)会影响该基础电容的值，基础电容的变化会导致触控电极的电荷量发生变化，对触控接收电极输出的电信号进行分析和运算，可以确定发生触控操作的触控电极的位置，从而确定触控操作在显示面板上的位置信息，显示面板根据触控操作显示相应的显示画面。Optionally, in the touch display panel provided by the embodiment of the present invention, the working mode of the touch electrodes 31 is mutual capacitance, and the touch electrodes include touch transmitting electrodes and touch receiving electrodes. After the touch transmitting electrode and the touch receiving electrode respectively receive electrical signals, a basic capacitance is formed between them. When a touch operation occurs on the touch display panel, the touch object (such as a finger) will affect the value of the basic capacitance. By analyzing and calculating, the position of the touch electrode where the touch operation occurs can be determined, thereby determining the position information of the touch operation on the display panel, and the display panel displays a corresponding display image according to the touch operation.
本发明实施例提供的触控显示面板中，触控发射电极和触控接收电极可以设置在同一层，也可以设置在不同层。下面，本发明在此示例性提供了两个实施例，分别说明触控发射电极和触控接收电极同层设置的技术方案，以及触控发射电极和触控接收电极异层设置的技术方案。In the touch display panel provided by the embodiments of the present invention, the touch transmitting electrodes and the touch receiving electrodes may be disposed on the same layer, or may be disposed on different layers.
