2. P7.62: The horizontal distance is 6mm, the vertical distance is 7.62mm, and the viewing distance is 30-80m

3. P10: The lamp bead spacing is 10mm, which is widely used in bus screens

2. Classification by color

1. Monochrome: generally has the colors of red, yellow, blue, green, and white lights, and is mainly used for displaying advertisements on the top of taxis, and displaying road sign information on the front and back sides of buses;

2. Two-color: One screen has two colors, mainly used for bus function screen; full color: also known as color screen, mainly used to display full-color advertising information for other types of car body, most of the area is relative to single and double color The car screen is larger and the production cost is higher, but the advertising effect is better.

When changing the content of the text in the screen, you need to connect the computer to change with a serial cable, or save the content to be changed into the U disk to save, and then plug it into the USB interface of the screen. (However, there can be no other content in the U disk)

2. GPRS type: When the car reaches a certain number, it will be very troublesome to change the content of the words one by one. Or it would be very troublesome to change the content of the word frequently, so directly using the computer remote control will bring more convenience to our customers, with less effort.
