Vehicle-mounted LED (Light Emitting Diode) display screen integrated with highlighters

Abstract

The invention discloses a vehicle-mounted LED (Light Emitting Diode) display screen integrated with highlighters in the technical field of the vehicle-mounted LED display screen. The vehicle-mounted LED display screen comprises a PCB (Printed Circuit Board), LED lamps and a control circuit, wherein a circle of highlighters are arranged at the periphery of the LED lamps; the control circuit comprises a power supply management system, a vehicle-mounted LED display screen control system, an SCM (Single Chip Microcomputer) and a control system bus interface; the power supply management system is connected with a vehicle-mounted power supply and control signals of vehicle taillights; the output end of the power supply management system is connected with the vehicle-mounted LED display screen control system and the SCM; the vehicle-mounted LED display screen control system and the SCM are both in driving connection with the vehicle-mounted LED display screen through the control system bus interface; the SCM is also connected with driving chips of the highlighters. According to the vehicle-mounted LED display screen disclosed by the invention, not only the requirement of installing a small-interval LED display screen in narrow and small space of a vehicle can be met, but also the requirements on cool, individuality and traffic safety warning and reminding on the vehicle-mounted LED display screen displayed by the highlighters can be met.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted LED display screens, in particular to a vehicle-mounted LED display screen integrated with bright marquees. Background technique [0002] In the field of vehicle-mounted LED display in the prior art, the content of the display screen is only displayed through the LED screen and controlled by a unified LED display screen control system. The prior art can't show the more comprehensive effect of synchronizing with the taillight signal of the car, and can't play a strong reminder. [0003] One solution is to use a marquee to enhance the display effect, but the traditional structure uses the display pixels of the display itself to display the marquee effect. There are many defects in this way: [0004] 1. The area of ​​the marquee occupies the display pixels of the LED display itself, and its display effect is affected. Especially in the vehicle-mounted LED display, after the marquee occupies...

AI Technical Summary

Problems solved by technology

[0004] 1. The area of ​​the marquee occupies the display pixels of the LED display itself, and its display effect is affected. Especially in the vehicle-mounted LED display, after the marquee occupies more pixels of the display itself, its display effect is obviously changed. Poor, even unable to display the complete picture normally

[0005] 2. The display pixels of the traditional marquee are all taken from the LED display itself, so the brightness of the marquee is at the same brightness level as the brightness of the LED display screen. If it is a small-pitch LED display, then the brightness Very low, when the outdoor brightness is very high, it is impossible to see clearly, and even the effect of the marquee cannot be seen

[0006] 3. In order to obtain the display effect of high-brightness marquee lights, larger high-brightness LED lights must be replaced to make the display screen. At this time, the area of ​​the LED display screen will increase, but the space in the car is very limited. When the area If it is too large, it may not be installed. If the area is made small, the screen display pixels will not be enough, and it will not be possible to display a clear video image
