Which is better, serial screen or parallel screen, which manufacturer do you use?

At present, it must be a serial screen that is easy to use, why?

The wiring pins and parallel port screen need to be connected by multiple wires, and the serial port screen only needs two wires to complete the communication.

In terms of program, most of the serial port screens on the market are intelligent, with configuration function, the usage is very simple and convenient, such as using the parallel port screen, the program is very complicated; Relatively speaking, the use of serial port screens, the amount of programs is less than that of parallel port screens, and even many serial port screens do not need the user's MCU microcomputer to control.

I have used the best products of Guangzhou Dacai Optoelectronics Technology, basic products, and the application is very convenient, whether it is a graduation project or an engineering project.

Hello, Guangzhou Dacai is happy to answer your questions:

The serial port screen is relatively better than the parallel port screen, which is mainly reflected in the following points:

1. The development cycle of serial port screen is fast;

2. The serial port screen has relatively high stability and good anti-interference ability, which can be applied to various fields.

3. The serial port screen is easy to upgrade.

The serial screen is good, and the ones used are all big colors and Diwen's.

Hengyuwei's serial port screen is also very easy to use, cost-effective, the key is good service, more stable than Diwen, and more high-end than Dacai. The service is really good.

The serial port screen is more cost-effective than the parallel port screen, the operation is convenient and simple, and the ones used are all big colors.

Serial port screen and parallel port screen have their own advantages.

The serial port screen is simple and easy to use, and the development of the supporting host computer is also relatively good. Simple wiring and fast development cycle.

Parallel port screen wiring complex development, but strong flexibility, developers can achieve more complex interaction ideas, do not need to be limited to the control of the serial port screen.

To put it simply, the serial port screen is developed on the parallel port screenIf you need custom development, you can contact me. Of course, we also provide standard serial screen productsThe serial port screen has implemented all the underlying drivers, so developers don't need to care, but there are limitations that they can only realize their own interaction logic in the functions supported by the serial port screen, and they can realize more human-computer interaction functions according to their own ideas.

In fact, I have used most of the serial port screens on the market, the powerful **too high, low**The functional requirements cannot be reached, so I tried an inch serial port screen of Shang Vision Technology, model: JC219, a treasure search JC219 can be, this serial port screen communication is simple, low, and has a translucent display effect (that is, no backlight can be displayed), I hope the landlord and everyone can give it a try, we are also making products, This serial screen has brought us a greatly reduced development and added more practical features to our products.

It is difficult to develop a parallel port screen,Unlike the serial port screen,You can soon develop a beautiful UI interface,YYSYThe UI interface is very good,You can go to their official website to take a look,One of the best in terms of peers。

First of all, blindly analyze a wave, the parallel port screen needs to be connected by multiple wires, and the serial port screen only needs two wires to complete the communication. At present, most of the serial port screens on the market are intelligent, with configuration function, the usage is very simple and convenient, such as the parallel port screen, the program is very complicated; Relatively speaking, the use of serial port screens, the amount of programs is less than that of parallel port screens, and even many serial port screens do not need the user's MCU microcomputer to control. Then to summarize briefly, the serial port screen is simpler than the parallel port screen.

The products on the market are all similar,At present, it is Taojingchi serial screen,They have an advantage over other homes is the self-developed interface development software usart HMI,Make interface development much simpler。

Purely in terms of material cost, the parallel port screen is cheaper, but if the development time is counted, the serial port screen is much faster, and the product is one step earlier to seize the market, and the development of the parallel port screen is not only to drive the screen display, but also to drive the touch chip, etc., the stability and efficiency of self-development is difficult to compare with the serial port screen company that specializes in making screens, our company has recently used the screen of Taojingchi, they also provide customized UI services, and the product appearance is directly improved by a grade.

Beijing Diwen Technology****.

Good quality.

The serial port screen is simple to operate and can achieve more complex functions, because it only needs to write the serial port to dismantle the potato handifold program to achieve menu, text, dynamic curve, ** operation, simply put, it is to do interface display, and through the configuration software can do data acquisition and process control, such as Taojing Travel Suspicion Serial Port Screen concise development interface software, so that interface development is not a problem for engineers, everyone can be a UI design master.

Recommend Dacai Technology's serial port screen, which mainly uses Cortex-M3 + high-speed FPGA + SDRAM dual-core processor.

The main advantages of the Cortex-M3+ FPGA "dual-core processor are:

1) FPGA is a programmable logic device with high frequency and parallel processing of internal instructions.

2) It can easily drive TFT with a resolution of 1440*900 or more, and the refresh speed is fast, and it can be driven by inches.

3) The whole system has no operating system or OS, pure hardware driver, and runs when it is powered on.

4) 24*365h continuous power supply can work reliably, no garbage redundant files.

5) M3 and FPGA are conventional devices, which have been in stock for more than 10 years.

Serial port screen refers to the LCD screen with serial port control, which is used in industrial automation, electric power, telecommunications, etc.
