While most mcus offer various low power modes – and some include lcd controllers on chip – the challenge, until recently, has been to keep energy consumption low while the lcd is powered up. The capacitor split method of generating the lcd bias voltages can halve the power consumption of these mcu based products compared to previous solutions.

Batteries aren''t really like capacitors at all aside from the fact that they can store energy.

Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can't provide energy as quickly as it is needed. Take, for example, the flashbulb in a camera.
The first, a battery, stores energy in chemicals. Capacitors are a less common (and probably less familiar) alternative. They store energy in an electric field. In either case, the stored energy creates an electric potential. (One common name for that potential is voltage.)
Batteries can provide a steady and continuous supply of power. They have a higher energy density compared to capacitors, making them suitable for applications that require longer-lasting energy storage. Batteries are commonly used in portable electronic devices, electric vehicles, and grid energy storage systems.
The amount of power that can be stored by any capacitor is directly related to the size of the metal plates within the battery. The larger the plate surface, the more energy the capacitor is able to store.
However, for devices that need consistent, long-term energy supply, a battery is still the best option. You can easily charge a capacitor using a battery. The charging process is quick, and this is commonly done in circuits where capacitors are used to smooth out power supplies or manage energy flow.
Not exactly. While you can use a capacitor to store some energy, its ability to replace a battery is limited due to its low energy storage capacity. Capacitors vs batteries aren't interchangeable, but in specific use cases, capacitors can complement or assist batteries.
