- the transparent conductive film 120 is disposed on the substrate 100.
- the substrate 100 is a polyester film substrate, that is, a PET substrate.
- the transparent conductive material of the display device (mainly the transparent conductive material of the transparent conductive film 120) is, for example, a dopant of indium tin oxide In2O3 and Sn2O3, and other materials, the colors of which are slightly different, and the price difference is large.
- the design of the conductive film needs to consider its own resistance.
- the transparent conductive material of the display device requires a small input impedance, because the touch chip always charges and discharges the display device when the system detects the button.
- the display device with the touch button further comprises: a silver glue line 130 electrically connected between the transparent conductive film 120 and the conductive film terminal 140.
- a silver glue line 130 electrically connected between the transparent conductive film 120 and the conductive film terminal 140.

Then, the insulating material layer 160 is printed, for example, to the area other than the conductive film 120 and the transparent window 150 to ensure that the silver glue line 130 is not exposed to the air to form an oxidation failure; at the same time, the adjacent conductive film 120 is ensured.
- the conductive insulating ink layer can block the area of the panel except the conductive film 120 and the transparent window 150, thereby ensuring the appearance of the display device, and the appearance of the display device when the power is turned off or not powered. For a complete mirror effect, the display and button content are hidden behind the panel. Preferably, as shown in FIG.
- the panel is provided with a clip 210 that is engaged with the conductive film terminal 140.
- the routing and setting of the conductive film terminals 140 are facilitated.
- the operation of the display device of the present invention will now be described.
- the solution of the present invention is based on the technology of a capacitive touch chip, each transparent conductive film 120 of the display device being connected to the input detection port of the touch chip.
- the touch chip senses that the capacitance on the transparent conductive film 120 corresponding to the position changes, the output level is detected, and the main IC of the display panel detects the low level for recognition.
- This position displays the contents of the button.
- the transparent conductive material of the display device transparent conductive film 120 is, for example, a dopant of indium tin oxide In2O3 and Sn2O3, and other materials, the colors are slightly different, and the price difference is large. For a touch chip requiring a small input impedance, the design of the conductive film needs to consider its own resistance.
- the transparent conductive material of the transparent conductive film of the display device requires a small input impedance, because the touch chip always performs the display device when the system detects the button. Charging and discharging, if the input impedance of the display device is too large, the signal of the touch chip to the conductive film will be consumed during the transmission, so that the conductive film cannot be charged and discharged, and the system cannot work normally.
- the rate p is on the order of 10 ⁇ 4
- the film thickness d is related to the selected material. If the material selected is better, the thicker the film thickness d, the smaller the R port can be seen according to the formula. Therefore, when the material properties are the same, selecting a material with a thick film thickness d can reduce the material.
- L1 is the line length in the direction of the parallel current
- L2 is the line length in the direction of the vertical current. Therefore, it can be seen that when the selected 1 ⁇ is not improved, it is considered to make the line of L1 as wide as possible.
- the display device since the display device is used as an input port of the touch chip, the display device inevitably has a line length of the display device that needs to be retained for a certain length, as a space when the terminal is inserted, After the plugging is completed, the cord must have excess parts left in the vicinity of the plug-in port, and even attached directly to the controller or the panel structural member, which cannot be fixed. Since the touch chip senses any change on the button, when the line of the display device is not fixed, it is easy to cause a certain change of the line of the display device due to vibration of the body or when the hand is pressed, thereby generating a false button. The situation happened.
- the present invention mainly includes the silver glue line 130 and the conductive film terminal 140 first being stuck to the panel by the clip 210. Then, the threading hole 230 opened on the controller is passed through the back of the controller to be docked and fixed by the plug-in terminal 240, so that the entire design avoids the problem of the wrong button caused by the unknown use condition, thereby preventing unnecessary generation.
- the invention conceals the button area by the design of the conductive film and the touch button circuit, is convenient for the user to use, and also makes the design compact.
- the appearance of the home appliance is more beautiful, and the display size is reduced, and the button operation is more vivid.
- the present invention can be applied to household appliances such as an air conditioner and a refrigerator, and a member such as a transparent conductive film 120 can be disposed under or behind a panel of a home appliance such as an air conditioner or a refrigerator.
- the display looks like a complete mirror effect, and the display and button content are hidden behind the display panel.
- the wire strip mainly includes the silver glue line 130 and the conductive film terminal 140 firstly fastened to the panel by the clip 210, and then passed through the threading hole 230 opened on the controller to the back of the controller through the mating terminal 240.
- the entire design is prevented from accidentally pressing the button due to an agnostic use situation, preventing unnecessary interference.

透明导电膜 120在触摸前没有通电显示, 即隐形起来, 在触摸后, 通过 印刷电路板上的集成电路控制显示区域进行通电显示, 因而无需在按键区域 特别标识各个按键的功能。 这样的设计克服了釆用传统的触摸按键的设置方 式影响显示屏的美观的问题, 进而达到显示屏结构紧凑, 外表美观的效果。 优选地, 显示装置还包括: 光源(图中未示出), 光源设置在印刷电路板 上并对应透明导电膜组件设置, 例如对应多块透明导电膜 120设置; 为显示 区域的显示提供光线或亮度, 这样, 便于规模化、 集成化制作。 当然, 光源 也可以设置在印刷电路板外的合适地方, 或显示装置不釆用光源, 而通过其 他方式为显示区域的显示提供亮度。 优选地, 如图 4所示, 对插端子 240 , 设置在控制器 220的印刷电路板 上, 对插端子 240具有适宜和导电膜端子 140对接的结构; 穿线孔 230 , 设 置在印刷电路板上, 穿线孔 230设置的较佳位置在印刷电路板中部, 或者距 印刷电路板的边缘保持明显的距离; 导电膜端子 140穿过穿线孔 230与对插 端子 240对接。 导电膜端子 140穿过穿线孔 230与对插端子 240对接, 能避 免按键的误操作。 优选地, 透明导电膜 120设置在基板 100上, 例如, 基板 100为聚脂薄 膜基板即 PET基板。 这样, 有利于提供合适的导电性能。 显示装置的透明导 电材料(主要是透明导电膜 120的透明导电材料 )例如是氧化铟锡 In2O3和 Sn2O3的掺杂物, 也有其它材料, 其颜色略有不同, 价格相差较大。 对于要 求输入阻抗较小的触摸芯片, 导电薄膜的设计需要考虑其自身电阻, 显示装 置的透明导电材料要求输入阻抗较小, 因为在***检测按键的时候, 触摸芯 片一直对显示装置进行充放电, 如果显示装置的输入阻抗过大, 则触摸芯片 给导电薄膜的信号会在传输途中消耗掉, 这样就不能对导电薄膜进行充放电, ***也就不能正常工作。 优选地, 具有触摸按键的显示装置还包括: 银胶线路 130 , 电连接在透 明导电膜 120和导电膜端子 140之间。 这样, 便于印制到 PET材料上, 形成 电连接。 优选地, 银胶线路 130与透明导电膜 120部分重合。 这样, 能保证 透明导电膜 120的导电效果。 如图 2所示,在导电膜 120前方(导电膜 120的左侧)设置透明视窗 150, 用双面胶 110将导电膜 120、 银胶线路 130和导电膜端子 140的组件粘在面 板 90的后方 (即面板的右侧;)。 显示区域 225可以设置在导电膜 120的正后
方 (导电膜 120的右侧;)。 制作时, 在 PET基板 100表面覆盖导电薄膜, 通过蚀刻手段, 将不需要 的区域去除,保留需要的按键部分, 制作成导电膜 120,再将银胶印制到 PET 材料上, 形成银胶线路 130。 注意印制时导电膜 120和银胶线路 130需要部 分重合, 保证这两种材料完全接触导通。 再将绝缘材料层 160 , 例如将绝缘油墨印刷到除导电膜 120、 透明视窗 150之外的区域, 保证银胶线路 130不暴露在空气中, 形成氧化失效; 同时, 保证相邻导电膜 120之间不会形成导通, 而且, 印刷绝缘油墨层能遮挡住面 板的除导电膜 120、 透明视窗 150之外的区域, 保证了显示装置的美观, 在 关机或未上电时, 显示装置外观上为一个完整的镜面效果, 显示和按键内容 隐藏在面板后面。 优选地, 如图 3所示, 面板上设有与导电膜端子 140卡接的卡夹 210。 这样, 便于导电膜端子 140的走线和设置。 下面介绍本发明的显示装置的工作原理。 本发明的方案是基于电容性触 摸芯片的技术, 显示装置的每个透明导电膜 120连接到触摸芯片的输入检测 口上。 当按键没有受到触摸时, 对应该按键位置的透明导电膜 120没有电容 的变化, 该按键不会有通电显示, 从而保证显示屏的美观和完整; 当手触摸 到某个位置上的按键上时。 通过印刷电路板上的集成电路的控制, 触摸芯片 感应到对应该位置的透明导电膜 120上的电容量发生变化时, 输出 氏电平, 显示板的主 IC检测到低电平进行识别, 在该位置, 显示按键的内容。 此外, 还可以使得其他未被触摸的区域不进行显示,从而突出地显示被触摸的按键, 达到醒目的效果。 显示装置透明导电膜 120 的透明导电材料例如是氧化铟锡 In2O3 和 Sn2O3的掺杂物也有其它材料, 其颜色略有不同, 价格相差较大。 对于要求 输入阻抗较小的触摸芯片, 导电薄膜的设计需要考虑其自身电阻, 显示装置 透明导电膜的透明导电材料要求输入阻抗较小,因为在***检测按键的时候, 触摸芯片一直对显示装置进行充放电, 如果显示装置的输入阻抗过大, 则触 摸芯片给导电薄膜的信号会在传输途中消耗掉, 这样就不能对导电薄膜进行 充放电, ***也就不能正常工作。
对于要求输入阻抗较小的情况下, 透明导电膜的透明导电材料要求选取 低方阻 ( ) 材料, 1口的大小与 p 自身电阻率和 d膜厚有关 Rn=p/d, —般 自身电阻率 p的 10·4数量级的, 膜厚 d和所选择的材料有关, 如果选择的材 料较好, 膜厚 d越厚, 根据算式可以看出 R口越小。 因此, 在材料特性相同的时候, 选择膜厚 d较厚的材料可以降低材料的
R口。 而实际走线也会影响整体显示装置的自身阻抗 R= Rn*Ll/L2。 L1是平 行电流方向的线路长度, L2是垂直电流方向的线路长度, 因此, 可以看出, 在所选择的 1^没有办法提高的时候, 可以考虑将 L1的线路尽量走宽。 对于未釆用本发明的安装方法的机型来说, 由于使用显示装置作为触摸 芯片的输入端口, 使得显示装置不可避免存在显示装置的线带需要保留一定 长度, 作为插接端子时的空间, 而插接好后, 线带一定会有多余部分遗留在 插线口附近,甚至直接贴到控制器上或者面板结构件上, 无法起到固定作用。 由于触摸芯片会感应按键上的任何变化, 在显示装置的线带未固定好的情况 下, 很容易因为机体的震动或人手按压的时候, 使显示装置的线带发生一定 变化, 从而产生误按键的情况发生。 为保证显示装置拆卸方便, 同时避免显示装置的线带固定不好引起的误 按键的情况, 本发明将线带主要包括银胶线路 130和导电膜端子 140先用卡 夹 210卡到面板上, 再通过控制器上所开的穿线孔 230穿到控制器背面通过 对插端子 240对接固定, 使整个设计避免因为不可知的使用情况发生的误按 键的问题, 防止产生不必要的千 4尤。 从以上的描述中,可以看出,本发明上述的实施例实现了如下技术效果: 本发明通过导电薄膜和触摸按键电路的设计, 将按键区域隐形起来, 方 便用户使用, 也使设计紧凑。 使家电外观更美观, 而且既减少了显示尺寸, 又使按键操作起来更鲜明。本发明可以适用于空调器和电冰箱等家用电器上, 可以在空调器和电冰箱等家用电器的面板下方或后方设置透明导电膜 120等 部件。 用户在关机或未上电时, 显示屏外观为一个完整的镜面效果, 显示和 按键内容隐藏在显示面板后面。 本发明将线带主要包括银胶线路 130和导电 膜端子 140先用卡夹 210卡到面板上, 再通过控制器上所开的穿线孔 230穿 到控制器背面通过对插端子 240对接固定, 使整个设计避免因为不可知的使 用情况发生的误按键的问题, 防止产生不必要的千扰。
以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
