图像处理 计算机图形学

## 显示处理器 **(**Display Processor**)** ##

**Display Processor** is a part of computer graphics which is used to convert the code into pictures. In other words, we can say that the **Display Processor** is used to convert the digital information or the digital signal into analog. Hence, the **display Processor** in simple terms can also be called *digital to analog converter*. The conversion in the Display Processors depends on the types of devices and the functions used for graphical representations.

**显示处理器**是计算机图形学的一部分，用于将代码转换为图片。 换句话说，可以说**显示处理器**用于将数字信息或数字信号转换为模拟信号。 因此，简单来说， **显示处理器**也可以称为*数模转换器* 。 显示处理器中的转换取决于设备的类型和用于图形表示的功能。

The main purpose of the Display Processor is scan conversion. Scan Conversion is a process of displaying different graphics objects as a collection of pixels. In this process, we have to differentiate graphics objects a collection of different mathematical shapes like ellipse, rectangle, and polygons. It is also called **Display Processing Unit**, DPU in short.

显示处理器的主要目的是扫描转换。 扫描转换是将不同图形对象显示为像素集合的过程。 在此过程中，我们必须区分图形对象，这些对象是不同数学形状的集合，例如椭圆，矩形和多边形。 它也被称为**显示处理单元** ，DPU短。

## 显示处理器的零件 **(**Parts of Display Processor**)** ##

There are 4 major parts of the Display Processor,

显示处理器有4个主要部分，

1.  Display File Memory
    
    显示文件存储器
2.  Display Controller
    
    显示控制器
3.  Display Generator
    
    显示产生器
4.  Display Console
    
    显示控制台

Now let us study about the usage and working of each of these parts.

现在让我们研究每个部分的用法和工作。

### 1)显示文件存储器 **(**1) Display File Memory**)** ###

It is used to display the pictures on the screen. The Display File Memory identifies the different graphics objects or entities. All the pixel values that are to be showed on the screen are there in the display File memory.

它用于在屏幕上显示图片。 显示文件存储器识别不同的图形对象或实体。 屏幕上所有要显示的像素值都在显示文件存储器中。

### 2)显示控制器 **(**2) Display Controller**)** ###

The Display Controller handles the flow instructions in the display processor. It is responsible for handling the interrupt and to maintain the timings between their executions. Interpretation of the instructions is also performed by the Display Controller.

显示控制器处理显示处理器中的流指令。 它负责处理中断并维持两次执行之间的时间间隔。 显示控制器也执行指令的解释。

### 3)显示产生器 **(**3) Display Generator**)** ###

Display Generator is used to generate characters and shapes on the screen. This displays the shapes and characters according to the input we give in it. In short, the Display Generator is used for generating curves and characters on the screen.

显示生成器用于在屏幕上生成字符和形状。 这将根据我们在其中输入的内容显示形状和字符。 简而言之，显示生成器用于在屏幕上生成曲线和字符。

### 4)显示控制台 **(**4) Display Console**)** ###

Display Console is a combination of a display device and an input device. This is the part of the Display Processor which shows the output on the screen. The Cathode Ray Tube comes under the Display Console. In common terms, the display console is the screen on which you see all your graphical outputs.

Display Console是显示设备和输入设备的组合。 这是显示处理器的一部分，在屏幕上显示输出。 阴极射线管位于显示控制台下方。 通常，显示控制台是您可以在其中看到所有图形输出的屏幕。

### 显示装置 **(**Display Devices**)** ###

Some Display Devices are listed below,

下面列出了一些显示设备，

*  Cathode Ray Tube
    
    阴极射线管
 *  Random Scan and Raster Scan
    
    随机扫描和光栅扫描
 *  Color CRT Monitors
    
    彩色CRT显示器
 *  Flat Panel Display
    
    平板显示器
 *  Lookup Table
    
    查找表
 *  Direct View Storage Tubes
    
    直视式存储管
