Electroluminescent (EL) backlight drivers are power supplies specifically designed to power electroluminescent backlights. These backlights are used to light up LCD screens, buttons, and other displays.
EL backlight drivers are a type of DC-DC converter, which converts a high voltage DC source into a low voltage DC output. This output is used to power the EL backlight, allowing it to produce a bright light.
EL backlight drivers are designed with a variety of features and specifications to meet the demands of different applications. They can be designed with a wide range of output voltages, from as low as 3V up to as high as 500V.
Current control and dimming capabilities are also common features in EL backlight drivers. These features allow the driver to adjust the brightness of the EL backlight, allowing it to be used in a variety of applications, such as automotive displays and consumer electronics.
EL backlight drivers are typically designed to be highly efficient, with a low power consumption. This helps to reduce operating costs and extend the life of the EL backlight. Additionally, these drivers are often designed with built-in protection features, such as overvoltage and overcurrent protection, to help protect the EL backlight from damage.
The use of EL backlight drivers is becoming increasingly popular due to the advantages they offer. They are reliable, efficient, and can be used in a variety of applications.
Additionally, they offer a cost-effective solution for lighting up LCD screens, buttons, and other displays. As such, EL backlight drivers are becoming increasingly popular in the consumer electronics industry.
The Global Electroluminescent Backlight Driver 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.
The next generation of iPads and MacBooks will soon be available. It is exciting that sales of high-end products will increase as a result of Apple implementing mini-LED backlight technology. Macroblock has been a longstanding player in the LED backlight market. In the second quarter of 2021, the company will introduce two new LED backlight driver integrated circuits (ICs), MBI6334 and MBI6353, which are anticipated to generate a lot of conversation in the display industry.
The following paragraphs will provide a thorough introduction to Macroblock’s LED backlight driver ICs, covering both common features based on various design architectures. The ability of mini-LED backlight technology to achieve “local dimming” sets it apart from traditional LCD backlight technology.
In other words, the backlight’s light sources are separated into several hundred or even thousands of LEDs, and each LED can be zone-controlled to vary from 100% brightness to total inactivity in areas of the image that are dark. As a result, mini-LED backlight technology’s local dimming capability, which can dim hundreds to thousands of zones, can enhance contrast in images and produce HDR experiences.
LCD monitors with mini-LED backlights can achieve HDR image specifications, but the more zones they have, the more driver ICs and wires they require, and the higher their cost. Currently, driver-integrated circuits (ICs) with high scan functions can efficiently resolve the issue.
Announcing the release of the first fully integrated micro-LED light engine in the industry for high-definition (HD) adaptive driving beam applications Nichia Corporation and Infineon Technologies AG.
The use of automotive LED lighting technology by automakers to improve road safety and driving comfort has grown significantly in recent years. In this sense, adaptive driving beams using matrix LED technology have emerged as a crucial headlight feature for focused road lighting. The joint development of a high-definition (HD) light engine with over 16,000 micro-LEDs for headlight applications was announced by Infineon and Nichia three years ago.
It’s worked out well. Working with a Tier 1 European company, the micro-LED matrix solution featuring the first fully integrated micro-LED light engine in the industry for HD adaptive driving beam applications will be installed in a premium German car. The solution has been tested under AEC (Automotive Electronics Council) qualification standards.
With the help of an integrated LED driver integrated circuit (IC) from Infineon, Nichia’s proprietary LED chip and micro-LED technology can drive each micro-LED separately via pulse-width modulation (PWM) control. Furthermore, for ideal thermal control, the driver integrated circuit (IC) monitors the temperature of each micro-LED independently and offers on-chip temperature monitoring.
High-speed video signal transmission from the light pattern generator unit is made possible by integrated video interfaces. This results in a significant increase in the µPLS light engine’s energy efficiency at a much smaller form factor.
