XV-440-10TVB-1-20 触摸屏主要应用于公共信息的查询、领导办公室

触摸面板是一种可接收触头等输入信号的感应液晶显示装置，也被称为“触摸显示屏”或“触摸面板”。当触碰显示屏上的图形按键时，XV-440-10TVB-1-20显示屏上的触感反馈机制可依据事先编程的程序驱动各种各样的相互连接装置。触摸屏可以取代机械式的按键面板，并通过液晶显示界面制造出栩栩如生的影音视频效果。作为一种全新的电脑输入设备，触摸屏是现阶段非常简单、便捷、自然的人机交互方式。它赋予了多媒体系统全新的面貌，是富有吸引力的全新升级多媒体系统交互机器设备。触摸屏主要应用于公共信息的查询、领导办公室、工业控制系统、国防指挥、电子游戏、KTV点歌点餐、信息化教学、房地产业预购等领域。使用触摸屏时，用户可以用手指或其他物块触摸安装在显示屏前端的触摸屏，系统软件会根据手指触摸的标志或菜单部位来精准定位选择信息输入。

触摸面板的工作原理是基于人体与面板的接触产生的电容变化来实现的。下面以投射电容式触摸屏为例进行说明：

投射电容式触摸屏是由印在聚酯上的两层透明菱形网格图案组成，XV-440-10TVB-1-20在这两层的中间又有一层光学透明的绝缘体。假设蓝色菱形上有一堆电子，由于中间有一层透明的绝缘体，所以它们无法移动到黄色菱形上。然而这些电子却能产生电场，使正电荷聚集在黄色菱形上，这种状态也被称为电容。

当把导电材料（如手指）靠近这个电容时，电场就会遭到破坏，从而改变黄色菱形上聚集的正电荷，使之迁移到手指上面来。这种变化会被手机处理器记录下来，通过沿蓝色菱形扫描电荷或电压的变化来检测出触摸的位置。与此同时，黄色菱形序列也会被扫描。每列蓝色菱形是连在一起的，每行黄色菱形也是如此，这样就形成了由蓝色菱形列和黄色菱形行组成的网格图案。

The touch panel is an inductive liquid crystal display device that can receive the input signal of the touch class, also known as the “touch display screen” or “touch panel”. When the graphical keys on the display are touched, the tactile feedback mechanism on the XV-440-10TVB-1-20 display drives a variety of interconnected devices according to a pre-programmed program. The touch screen can replace the mechanical button panel and create lifelike audio and video effects through the LCD display interface. As a new computer input device, touch screen is a very simple, convenient and natural way of human-computer interaction at this stage. It gives the multimedia system a new look, is an attractive new upgrade multimedia system interactive machine equipment. Touch screen is mainly used in public information inquiry, leadership office, industrial control system, national defense command, electronic games, KTV song ordering, information teaching, real estate industry pre-purchase and other fields. When using the touch screen, the user can touch the touch screen installed on the front of the display screen with a finger or other objects. The system software will accurately locate and select information input according to the sign or menu part touched by the finger.

The working principle of the touch panel is based on the capacitance changes generated by the contact between the human body and the panel. The following takes the projection capacitive touch screen as an example:

The projected capacitive touch screen is composed of two layers of transparent diamond mesh pattern printed on polyester, and the XV-440-10TVB-1-20 has another layer of optically transparent insulator in the middle of these two layers. Suppose you have a bunch of electrons on the blue diamond, but they can’t move onto the yellow diamond because there’s a transparent insulator in the middle. These electrons, however, produce an electric field that causes the positive charge to concentrate in a yellow diamond, a state also known as capacitance.

When a conductive material (such as a finger) is placed close to this capacitor, the electric field is destroyed, changing the positive charge that accumulates on the yellow diamond and causing it to migrate to the finger. This change is recorded by the phone’s processor, which detects the location of the touch by scanning for changes in charge or voltage along the blue diamond. At the same time, the yellow diamond sequence is also scanned. Each column of blue diamonds is linked together, as is each row of yellow diamonds, thus forming a grid pattern consisting of blue diamond columns and yellow diamond rows.
