Display drivers are integrated circuits (ICs) that provide translation, interface and control between a microprocessor (MPU), microcontroller (MCU) or other circuitry system for displays such as LCD, LED, OLED, DLP, vacuum fluorescent and AMOLED. Possible interfaces and protocols for communication include analog, BCD, I2C, parallel, serial, SMBus, SPI and QSPI.
Display Drivers Power Management Integrated Circuits (PMICs) are specialized components designed to manage the power requirements of display systems in electronic devices. They regulate and distribute power to various parts of a display, ensuring optimal performance and efficiency. These ICs convert input power into the necessary voltage and current levels required by different sections of a display, such as the backlight, touch screen, and pixel drivers. By doing so, they help maintain the display's brightness, contrast, and color accuracy while minimizing power consumption and heat generation.
Types of Display Drivers PMICs
1. LCD Display Drivers PMICs
These PMICs are tailored for Liquid Crystal Displays (LCDs), providing the necessary voltage levels for the backlight and driving the liquid crystals. They often include features like gamma correction and timing control to enhance image quality. LCD Display Drivers PMICs are known for their efficiency in managing power for large and small screens alike.
2. OLED Display Drivers PMICs
Organic Light Emitting Diode (OLED) displays require precise voltage control due to their self-emissive nature. OLED Display Drivers PMICs are designed to deliver accurate power to each pixel, ensuring vibrant colors and deep blacks. They often support high refresh rates and low power consumption, making them ideal for portable devices.
3. LED Display Drivers PMICs
These PMICs are used in displays that utilize Light Emitting Diodes (LEDs) for illumination. They provide the necessary current regulation to maintain consistent brightness and color uniformity across the display. LED Display Drivers PMICs are commonly used in large-scale displays, such as billboards and stadium screens.
How to choose Display Drivers PMICs?
When selecting Display Drivers PMICs, consider the following key parameters:
Voltage and Current Requirements: Ensure the PMIC can handle the voltage and current levels needed by your display type.
Efficiency: Look for PMICs with high efficiency to reduce power loss and heat generation.
