PP825 触摸屏  用于检测用户触摸位置

PP825触摸屏（Touch Panel）又称为“触控屏”、“触控面板”，是一种可接收触头等输入讯号的感应式液晶显示装置，当接触了屏幕上的图形按钮时，屏幕上的触觉反馈系统可根据预先编程的程式驱动各种连结装置，可用以取代机械式的按钮面板，并借由液晶显示画面制造出生动的影音效果。

PP825触摸屏由触摸检测部件和触摸屏控制器组成。触摸检测部件安装在显示器屏幕前面，用于检测用户触摸位置，接受后送触摸屏控制器；而触摸屏控制器的主要作用是从触摸点检测装置上接收触摸信息，并将它转换成触点坐标，再送给CPU，它同时能接收CPU发来的命令并加以执行。

如今，已经形成了商业化的触摸屏技术包括：电阻技术触摸屏、电容技术触摸屏、红外线技术触摸屏、表面声波（SAW）PP825技术触摸屏等，并已广泛应用到了手机、平板电脑、零售业、公共信息查询、多媒体信息系统、医疗仪器、工业自动控制、娱乐与餐饮业、自动售票系统、教育系统等许多领域。

面板是用于显示文字和图像的屏幕部分，通常是一块透明的玻璃或塑料，位于显示器的前面。

显示面板是整个显示器的核心部件，主要由大量的发光二极管组成，负责产生光线并传递到我们的眼睛中。

显示面板的分辨率决定了图像的清晰度，分辨率越高，显示的图像越清晰。

面板还可以分为TN、IPS、VA等类型，每种类型都有其特点。例如，TN面板响应速度快，但色彩表现一般；PP825IPS面板色彩表现优秀，但价格较高；VA面板则介于两者之间。

面板的尺寸也是多种多样的，常见的有19英寸、24英寸、27英寸等，可以根据个人需求选择合适的尺寸。

PP825 触摸屏  用于检测用户触摸位置

PP825 Touch Panel (Touch Panel), also known as "touch screen", "touch panel", is a kind of induction liquid crystal display device that can receive touch input signals, when touching the graphic button on the screen, the haptic feedback system on the screen can drive a variety of connecting devices according to a pre-programmed program, which can be used to replace the mechanical button panel. And through the LCD screen to create a vivid audio-visual effect.

The PP825 touch screen consists of a touch detection unit and a touch screen controller. The touch detection component is installed in front of the display screen to detect the user's touch position and accept the rear touch screen controller; The main function of the touch screen controller is to receive touch information from the touch point detection device, convert it into contact coordinates, and then send it to the CPU, which can also receive the command sent by the CPU and execute it.

Today, commercialized touch screen technologies that have been formed include: Resistive technology touch screen, capacitive technology touch screen, infrared technology touch screen, surface acoustic wave (SAW) PP825 technology touch screen, etc., and has been widely used in mobile phones, tablet computers, retail, public information inquiry, multimedia information system, medical instruments, industrial automatic control, entertainment and catering industry, automatic ticketing system, education system and many other fields.

The panel is the part of the screen used to display text and images, usually a piece of clear glass or plastic, located in the front of the display.

The display panel is the core component of the entire display, mainly composed of a large number of light-emitting diodes, responsible for generating light and delivering it to our eyes.

The resolution of the display panel determines the clarity of the image, and the higher the resolution, the clearer the image displayed.

The panel can also be divided into TN, IPS, VA and other types, each type has its own characteristics. For example, the TN panel is fast in response, but the color performance is mediocre; PP825IPS panel color performance is excellent, but the price is higher; The VA panel is somewhere in between.

The size of the panel is also a variety of, common 19 inches, 24 inches, 27 inches, etc., you can choose the right size according to your personal needs.
