Description

A circuit structure compatible with an intelligent vehicle terminal LCD and an LED display panel

technical field

The utility model relates to a circuit structure compatible with an intelligent vehicle-mounted terminal LCD and an LED display board. the

Background technique

What the existing intelligent vehicle-mounted terminal generally adopts is LED display. With the development of integrated circuit technology, smart vehicle-mounted terminals can perform more and more functions, and the corresponding amount of information that needs to be displayed is also increasing. When LED display cannot meet the application of smart vehicle-mounted terminals with higher intelligence, An LCD with a large amount of displayed information can be used as a display device for display. Therefore, as an updated product, smart vehicle terminals will generally use LCD displays. the

However, the market demand determines the product style. At present, there is still a large market demand for smart vehicle terminals with LED displays. Therefore, when developing products, a manufacturer of smart vehicle terminals must develop two types of motherboards to adapt to LCD or LED displays. Application, when the LED display terminal and the LCD display terminal are converted to each other, it is necessary to replace the entire motherboard, or even replace the entire device. This just makes product production cost higher and causes the waste of resources. Therefore, a circuit structure compatible with the LCD of the intelligent vehicle-mounted terminal and the LED display board needs to be developed urgently to solve the above-mentioned problems. the
