技术领域technical field

本发明是关于一种触控结构以及包含该触控结构的触控显示装置。具体而言，本发明是关于一种设置于显示面板显示面的一相对面上的触控结构以及包含该触控结构的触控显示装置。The invention relates to a touch structure and a touch display device including the touch structure. Specifically, the present invention relates to a touch structure disposed on an opposite surface of a display panel and a touch display device including the touch structure.

背景技术Background technique

输入设备是电脑外设装置中不可或缺的重要组件，通过输入设备的操作，使用者才得以对电脑进行控制，目前市面上常见的电脑输入设备包含键盘、鼠标、演示文稿器以及手写板等。使用者可视其本身的需求，来决定使用何种输入设备。然而，大部分的输入设备多需要学习特定的使用方式，例如鼠标或手写板的操作，或是键盘的输入法等较迂回的方式，对于使用者而言，前述使用方式皆较不直观。The input device is an indispensable and important component of the computer peripheral device. Through the operation of the input device, the user can control the computer. Currently, the common computer input devices on the market include keyboard, mouse, presentation device and tablet, etc. . Users can decide which input device to use according to their own needs. However, most of the input devices need to learn a specific way of use, such as the operation of the mouse or tablet, or the more roundabout way of inputting the keyboard. For the user, the aforementioned ways of use are not intuitive.

为了让使用者能够更直觉地操作电脑系统，触控式的相关输入设备因而发展，其中，又以触控式输入设备结合显示装置而形成的触控式屏幕较为常见。于触控式屏幕的架构中，电脑系统可通过显示装置展现其操作界面，搭配触控式输入设备的使用，使得使用者可以直觉式地于显示装置上直接进行相关的操作。目前此种方式已普遍的使用，包括手机、移动助理、卫星导航装置以及电子书等等。In order to allow users to operate computer systems more intuitively, related touch-type input devices have been developed. Among them, touch-type screens formed by combining touch-type input devices with display devices are more common. In the structure of the touch screen, the computer system can display its operation interface through the display device. With the use of the touch input device, the user can intuitively perform related operations directly on the display device. At present, this method has been widely used, including mobile phones, mobile assistants, satellite navigation devices and e-books and so on.

然而，目前所使用的触控式屏幕，其触控式输入设备皆是放置于显示装置的一显示面上以达功效。换句话说，为了使得显示装置所展现的内容得以被使用者所视，触控式输入设备需同时具备可透视以及触控等特性，因此，一般而言，触控式输入设备会使用较昂贵的玻璃或是透明导电膜(Indium Tin Oxide，ITO)作为基材。另外，除了材料昂贵的缺点，由于触控输入设备需置于显示装置的显示面上，此亦将导致显示装置的可视亮度降低，进而造成使用者视觉上的疲累。However, in the currently used touch screens, the touch input devices are all placed on a display surface of the display device to achieve functions. In other words, in order to allow users to view the content displayed by the display device, the touch input device must have the characteristics of see-through and touch control. Therefore, generally speaking, the touch input device will be more expensive to use. Glass or transparent conductive film (Indium Tin Oxide, ITO) as the substrate. In addition, in addition to the disadvantage of expensive materials, since the touch input device needs to be placed on the display surface of the display device, this will also reduce the visible brightness of the display device, thereby causing visual fatigue to the user.

综上所述，如何满足触控式屏幕可以同时降低制作成本以及增加可视亮度，是业界亟需努力的目标。To sum up, how to satisfy the need of the touch screen to reduce the production cost and increase the visible brightness at the same time is an urgent goal in the industry.

为达前述目的，本发明提供一种用于一触控显示装置的触控结构，该触控显示装置具有一触控控制器，与该触控结构电性连接。该触控结构包含一显示面板以及一感测总成。其中，该显示面板具有一显示面；该感测总成是设置于该显示面的一相对面且与该触控控制器呈电性连接，用以于该显示面板的显示面被触碰时，产生一触碰信号，以便该触控控制器可根据该触碰信号动作。To achieve the aforementioned purpose, the present invention provides a touch structure for a touch display device. The touch display device has a touch controller electrically connected to the touch structure. The touch structure includes a display panel and a sensing assembly. Wherein, the display panel has a display surface; the sensing assembly is arranged on an opposite surface of the display surface and is electrically connected with the touch controller, for when the display surface of the display panel is touched to generate a touch signal, so that the touch controller can act according to the touch signal.

首先，请先参考图1，其为本发明的一触控显示装置1的示意图。触控显示装置1包含一触控控制器11以及一触控结构13，触控控制器11是与触控结构13呈电性连结，用以根据触控结构13所传来的一触碰信号(未标示)而产生相对应的动作。该触碰信号的产生原理将于稍后的段落中详述。First of all, please refer to FIG. 1 , which is a schematic diagram of atouch display device 1 of the present invention. Thetouch display device 1 includes atouch controller 11 and atouch structure 13, thetouch controller 11 is electrically connected with thetouch structure 13, and is used to transmit a touch signal according to thetouch structure 13. (not marked) to generate the corresponding action. The principle of generating the touch signal will be described in detail in later paragraphs.

请同时参考图2，其为触碰结构13的示意图。触碰结构13包含一显示面板131以及一感测总成133。显示面板131具有一显示面1311，而感测总成133是设置于显示面的一相对面，通过上述的配置，显示面1311所呈现的画面，将可在可视亮度不因被感测总成133遮蔽而降低的情况下，直接地呈现给使用者，而感测总成133则是用以于显示面板131的显示面1311被使用者触碰时，产生该触碰信号。接下来，将进一步解说感测总成133的组成以及该触碰信号是如何产生与传递至触控控制器11，以完整呈现本发明。Please also refer to FIG. 2 , which is a schematic diagram of thetouch structure 13 . Thetouch structure 13 includes adisplay panel 131 and asensing assembly 133 . Thedisplay panel 131 has adisplay surface 1311, and thesensing assembly 133 is arranged on an opposite surface of the display surface. Through the above-mentioned configuration, the picture presented on thedisplay surface 1311 will be able to be displayed at a visible brightness without being sensed. In the case of being lowered under the cover of 133 , it is directly presented to the user, and thesensing assembly 133 is used to generate the touch signal when thedisplay surface 1311 of thedisplay panel 131 is touched by the user. Next, the composition of thesensing assembly 133 and how the touch signal is generated and transmitted to thetouch controller 11 will be further explained to fully present the present invention.

请一倂参阅图2以及图3，其中图3为感测总成133的分解示意图。由图3可知，感测总成133包含具有多个第一导体1332的一第一感测层1331、具有多个第二导体1334的一第二感测层1333、相对应于第一导体1332设置的第一导线1335、相对应于第二导体1334的第二导线1336以及一绝缘层1337。须特别强调的是，第一感测层1331以及第二感测层1333的材料可以为具有可挠性的聚氯乙烯(polyvinyl chloride)、聚对苯二甲酸二乙酯(polyethylene terephthalate)、聚亚酰胺(polyimide)、聚醚醚酮(polyetheretherketone)、聚萘二甲酸乙二醇酯(polyethylene naphthalene-2，6-dicarboxylate)等基材或上述基材的组合，而第一导体1332以及第二导体1334的材料可为金、铜、碳、银或锡等可以导电的材料，然而上述的材料仅为实施例中的范例，并不以此为限。Please refer to FIG. 2 and FIG. 3 together, wherein FIG. 3 is an exploded schematic diagram of thesensing assembly 133 . It can be seen from FIG. 3 that thesensing assembly 133 includes afirst sensing layer 1331 having a plurality offirst conductors 1332, asecond sensing layer 1333 having a plurality ofsecond conductors 1334, and corresponding to thefirst sensing layer 1332. Afirst wire 1335 , asecond wire 1336 corresponding to thesecond conductor 1334 and aninsulating layer 1337 are provided. It should be emphasized that the material of thefirst sensing layer 1331 and thesecond sensing layer 1333 can be flexible polyvinyl chloride (polyvinyl chloride), polyethylene terephthalate (polyethylene terephthalate), polyethylene Substrates such as polyimide, polyetheretherketone, polyethylene naphthalene-2,6-dicarboxylate or a combination of the above substrates, while thefirst conductor 1332 and the second The material of theconductor 1334 can be a conductive material such as gold, copper, carbon, silver or tin, but the above-mentioned materials are only examples in the embodiment and are not limited thereto.

绝缘层1337是设置于第一感测层1331以及第二感测层1333之间，用以电性绝缘第一导体1332以及第二导体1334，具体说，绝缘层1337包含多个块体1338，其可于第一感测层1331以及第二感测层1333间界定出多个空间，第一导体1332以及第二导体1334将被这些空间隔离以达到绝缘的目的，于本实施例中，块体1338的材料可为聚氯乙烯或光阻等具有不导电性质的材料，于其它实施例中，块体133可由其它具绝缘功效的材料所制成，并不以此为限。Theinsulating layer 1337 is disposed between thefirst sensing layer 1331 and thesecond sensing layer 1333 to electrically insulate thefirst conductor 1332 and thesecond conductor 1334. Specifically, theinsulating layer 1337 includes a plurality ofblocks 1338, It can define a plurality of spaces between thefirst sensing layer 1331 and thesecond sensing layer 1333, and thefirst conductor 1332 and thesecond conductor 1334 will be separated by these spaces to achieve the purpose of insulation. In this embodiment, the blocks The material of thebody 1338 can be non-conductive material such as polyvinyl chloride or photoresist, and in other embodiments, theblock body 133 can be made of other materials with insulating effect, but not limited thereto.

此外，第一导体1332以及第二导体1334可分别通过第一导线1335以及第二导线1336与触控控制器11呈电性连接，于本实施例中，触控控制器11可通过第一导线1335，依序提供一扫描电压(未绘示)至各第一导体1332，于显示面板131的显示面1311被使用者触碰时，第一感测层1331将会因应此触碰而朝第二感测层1333方向变形/下凹，致使第一导体1332通过前述由块体1338于第一感测层1331以及第二感测层1333间所界定出的空间与第二导体1334接触，而呈现导通状态，此时扫描电压便可由第一导体1332传导至第二导体1334以产生该触碰信号，再通过第二导线1336将该触碰信号传回至触控控制器11，以便触控控制器11判断触碰的位置。In addition, thefirst conductor 1332 and thesecond conductor 1334 can be electrically connected to thetouch controller 11 through thefirst wire 1335 and thesecond wire 1336 respectively. In this embodiment, thetouch controller 11 can be electrically connected through the first wire. 1335 , sequentially provide a scanning voltage (not shown) to each of thefirst conductors 1332 , when thedisplay surface 1311 of thedisplay panel 131 is touched by the user, thefirst sensing layer 1331 will move toward the second conductor in response to the touch. The direction of thesecond sensing layer 1333 is deformed/concave, so that thefirst conductor 1332 is in contact with thesecond conductor 1334 through the space defined by theblock body 1338 between thefirst sensing layer 1331 and thesecond sensing layer 1333, and In the conduction state, the scanning voltage can be transmitted from thefirst conductor 1332 to thesecond conductor 1334 to generate the touch signal, and then the touch signal is transmitted back to thetouch controller 11 through thesecond conductor 1336, so as to touch Thecontroller 11 determines the position of the touch.

具体而言，本实施例的第一导体1332皆是水平且独立地设置于第一感测层1331上，而第二导体1334皆是垂直且独立地设置于第二感测层1332上，因此，于俯视显示面1311时，第一导体1332以及第二导体1334将实质上共同产生许多类似格点的交叉处，触控控制器11便能够轻易地利用坐标的原理，判断出哪个位置产生了电性连结，进而判断触碰产生的位置。Specifically, thefirst conductors 1332 of this embodiment are all horizontally and independently disposed on thefirst sensing layer 1331, and thesecond conductors 1334 are all vertically and independently disposed on thesecond sensing layer 1332, therefore , when looking down on thedisplay surface 1311, thefirst conductor 1332 and thesecond conductor 1334 will substantially jointly generate many intersections similar to grid points, and thetouch controller 11 can easily use the principle of coordinates to determine which position generates Electrical connection, and then determine the location of the touch.

举例来说，当触控控制器11通过第一导线1335a，提供该扫描电压至第一导体1332a时，如使用者触碰显示面板131的显示面1311，将使得第一导体1332a以及第二导体1334a接触而呈现导通状态，则第二导体1334a可据以将该扫描电压转换成该触碰信号，随后再通过第二导线1336a将该触碰信号传回至触控控制器11，如此一来，触控控制器11便可得知压力是产生于第一导体1332a以及第二导体1334a重叠处，进而判断压力的位置。而利用上述的原理，当压力越大，第一导体1332以及第二导体1334的重叠处将会增加，因此便可同时据以判断压力的大小；而且，多点触控的检测亦可同时实现。For example, when thetouch controller 11 provides the scanning voltage to thefirst conductor 1332a through the first wire 1335a, if the user touches thedisplay surface 1311 of thedisplay panel 131, thefirst conductor 1332a and the second conductor will be 1334a is in a conductive state, and thesecond conductor 1334a can convert the scanning voltage into the touch signal, and then transmit the touch signal back to thetouch controller 11 through thesecond conductor 1336a. Then, thetouch controller 11 can know that the pressure is generated at the overlap of thefirst conductor 1332a and thesecond conductor 1334a, and then determine the position of the pressure. Using the above-mentioned principle, when the pressure is greater, the overlap between thefirst conductor 1332 and thesecond conductor 1334 will increase, so the pressure can be judged at the same time; moreover, the multi-touch detection can also be realized simultaneously. .

综上所述，本发明通过前述的配置，将可使得触控结构不必设置于显示面上，如此触控结构将不需使用昂贵的透明材质作为触控结构的基板，亦可同时避免因显示面板的显示面被感测总成遮蔽而降低亮度，藉此，本发明是可有效地解决先前技术的问题。To sum up, through the aforementioned configuration, the present invention will make the touch structure unnecessary to be arranged on the display surface, so that the touch structure will not need to use expensive transparent materials as the substrate of the touch structure, and can also avoid the display due to The display surface of the panel is blocked by the sensing assembly to reduce the brightness, thereby, the present invention can effectively solve the problems of the prior art.

上述的实施例仅用来例举本发明的实施态样，以及阐释本发明的技术特征，并非用来限制本发明的范畴。任何熟悉此技术者可轻易完成的改变或均等性的安排均属于本发明所主张的范围，本发明的权利范围应以申请专利范围为准。The above-mentioned embodiments are only used to illustrate the implementation of the present invention and explain the technical features of the present invention, and are not intended to limit the scope of the present invention.
