How to upgrade the system of the in-car large screen

1. Upgrade of in-car navigationThe method is: take out the memory card in the navigation directly, then find the required navigation system on the Internet, download it and re-enter the memory card. It should be noted that if the port parameters of the original car system of the system used, the embedded can only be updated through the 4S store or repair factory.

2. It is recommended to go to the 4s store to upgrade the central control screen. The central control includes a central control door lock system. The driver can control the door switch and glass lifting system of the whole vehicle through the central control of the car. It also includes a central console, an audio control panel and other vehicle controllers.

3. Update the on-board system, replace the on-board display, etc. Update the on-board system. You can go to the 4S store to update the original on-board system, or you can download the latest version of the corresponding model's on-board system installation and upgrade through the official website of the corresponding model.

4. On-board large screen upgrade system method: open the resource link, download the file, and copy the downloaded file to the root directory of the USB flash drive. Before copying, you must clear the empty USB disk content and then format it. Press the MENU and NAV buttons at the same time for 5 seconds, and the central control system will pop up the system upgrade interface, then press the software upgrade, and then click the main control upgrade.

5. Android large-screen navigation flash. Use a USB flash drive of more than 16G to the official website of the vehicle to download the latest Apple car computer system and download it to the USB flash drive. After plugging the USB flash drive into the USB socket on the car, select the system upgrade button on the car computer system interface.

Large-screen design-The difference between large-screen design and APP design

App: Smooth animation, no stuttering, and the basics you want can be achieved. Applet: The animation ability is lower than that of H5 and App, and the animation consumes a lot of performance, especially on Android models, and the stuttering is slightly obvious.

The difference between the computer design concept map and the mobile app design concept map is the difference in design elements and design considerations.

Graphic design, also known as visual communication design, uses "vision" as a way of communication and expression, creating and combining symbols, pictures and words in a variety of ways to make visual expressions used to convey ideas or messages.

What are the categories of large-screen projection systems?

CRT projection CRT is the abbreviation of Cathode Ray Tube in English, which means cathode ray tube.

It is divided into three types according to different projection methods: front projection, back projection and combination splicing. The display screen of projection equipment is generally much larger than the CRT monitor, so it is often used as the main monitor in the monitoring system. CRT is an abbreviation of English (Cathode Ray Tube), which translates as cathode ray tube.

CRT three-gun projector CRT is the abbreviation of Cathode Ray Tube, which translates as cathode ray tube. As an imaging device, it is the earliest and most widely used display technology.

According to the electro-light effect, liquid crystal materials can be divided into two categories: active liquid crystal and inactive liquid crystal, among which active liquid crystal has high light transmittance and controllability. The liquid crystal panel uses active liquid crystal, and people can control the brightness and color of the liquid crystal panel through the relevant control system.

DLP large-screen projection splicing wall is currently the most advanced and "expensive" display system. Its "expensiveness" is not only reflected in the hardware investment in the early stage, but also in the maintenance costs and consumables costs in the later stage.

Projection screens can usually be divided into positive projection screens and back projection screens.The front screen is divided into soft screen and hard screen, among which the soft screen includes white screen, pearlescent screen and metal screen; the hard screen includes flat screen and curved screen; the back projection screen can also be divided into soft screen and hard screen, among which the back projection hard screen is more used.

What specific contents does the design scheme of DLP large-screen splicing system include?

The true color technology DLP large-screen engine adopts digital color balance and hybrid circuit, which can effectively ensure a high degree of consistency of brightness and color.

dlp's large screen size without splicing can be flexibly formulated; Pentel has set up a professional design team, which can design the most cost-effective large-screen display system according to the size of the installation space or the needs of the owner.There is no limit on the length, and the most reasonable size can be designed according to the requirements of the other party.

The information receiving system should not only receive VGA, RGB and network computer information, but also receive broadband voice and video signals, and be able to carry out appropriate information conversion as needed.
