1、The function and working principle of the head-up display
The car head-up display projects important driving information such as speed and navigation onto the windshield in front of the driver, so that the driver can see important driving information such as speed and navigation without lowering his head or turning his head. The large current required for a large number of calculations during projection is accompanied by greater ripple disturbance and voltage fluctuation, and the operation of the DCU (engine controller) requires stable voltage and elimination of ripple noise interference. Yongming solid-liquid hybrid aluminum electrolytic capacitors have low ESR characteristics. During the operation of the whole machine, they can filter out line ripple noise as much as possible to ensure the stable operation of the head-up display. At the same time, the capacitor must have powerful energy storage and smoothing functions. Ensure the continuous stability of the working voltage.
2、Automobile head-up display - capacitor selection and recommendation
Shanghai Yongming solid-liquid hybrid aluminum electrolytic capacitors have the characteristics of low ESR, large ripple current resistance, excellent shock resistance, high reliability, wide temperature stability, and wide frequency stability, ensuring the continuous stability of the working voltage. Perfectly solves the problem of unstable operating current of vehicle head-up displays.
