A LCD Bias Supply is a type of power supply that provides power and voltage regulation for a liquid crystal display (LCD). It provides the necessary electrical signals to the liquid crystal material for it to operate correctly.
The LCD Bias Supply is a critical component in LCD displays, providing the correct voltage and current levels for the liquid crystal material to change its state from opaque to transparent. The LCD Bias Supply also helps to maintain a consistent image quality across the display area.
The LCD Bias Supply typically consists of three main elements: the power source, voltage regulator, and current limiter. The power source provides electrical power to the rest of the circuit.
A voltage regulator is used to maintain a steady voltage level across the liquid crystal material. The current limiter prevents the LCD Bias Supply from delivering too much current, which can damage the liquid crystal material.
Finally, the LCD Bias Supply also includes various protection circuits to protect the display from being damaged due to unexpected power surges or other external conditions.
LCD Bias Supplies are typically used in LCD displays for electronics such as laptops, mobile phones, and monitors. They are also used in other applications such as industrial and medical devices.
LCD Bias Supplies provide an efficient and cost-effective way to power LCDs, as they are relatively small and consume very little power. They are also relatively easy to design and configure, making them ideal for custom applications.
The Global LCD Bias Supply market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Kinetic Technologies, a high-performance analog, and mixed-signal semiconductor company unveiled the KTD2150 and KTD2151 product families, LCD bias supplies for Full HD panels used in smartphones. Kinetic Technologies is focused on creating power management solutions for the computing, consumer, industrial, and communications markets. Due to its wide input voltage range, the converter is perfect for devices that run on single-cell Lithium-ion batteries, such as smartphones and other portable electronics.
The newest products in Kinetic’s System Power product line are the KTD2150 and KTD2151 product families. The dual-output products power the bias voltages required by the most recent generation of FHD panels in smartphones by delivering both positive and negative voltages using a single inductor. With an efficiency of up to 90%, the KTD2150 sets a new benchmark for this product category.
KTD2151 provides 100mV steps of I2C programmable output voltage for the positive and negative outputs, respectively. The KTD2150 provides a greater output voltage range, more precise programming, and customizable headroom settings for up to 90% efficiency. It can also be configured to disable I2C inputs, resulting in a shutdown current of less than 1uA.
