The Integrated System Exhibition (ISE) 2024 will feature Macroblock's "Taking LED Displays to New Heights with Macroblock Driver ICs" theme, which highlights common cathode driver ICs for LED displays in various application situations.
The following are some examples of the significant advancements in visual effects achieved by MBI5762 and new products like MBI5756: 1. Hyper Vision Calculation II technology has two functions that can more gently enhance the display picture quality under human eyes and camera lenses.
Low-gray Refresh Function: Reduces screen flickering considerably and increases the refresh rate of low-gray pictures.
The MBI5762's adaptive refresh function enhances the overall image's refresh rate by drastically lowering scan lines and black bands. It also supports dynamic frame rate change up to 240 frames per second, making it appropriate for slow-motion and multi-camera photography.
2. Better visual uniformity, which includes enhanced performance in blocks, high contrast interference, vertical stripes, and horizontal stripes.
First demonstration: MBI5762
The popular cathode driver integrated circuit MBI5762 was created especially for virtual manufacture. Displays with a pitch of 0.9mm to 4.0mm may use it. The printed circuit board is made simpler by raising the number of channels to 48 in order to replace the conventional high-scan in small-pitch displays. By achieving 16-bit grayscale and 7,680Hz refresh rate, it not only improves image quality but also lessens the issue of poor low-gray uniformity brought on by high-scan. Additionally, the MBI5762 supports dynamic frame rate modification up to 240 frames per second, which is useful for slow-motion and multi-camera photography.
2. MBI5754/MBI5756 Demo
A common cathode LED driver integrated circuit (IC) for general displays, the MBI5754 is appropriate for displays with a pitch between 0.9 and 6.0 mm. It makes use of the industry-standard package SSOP/QFN, has an internal DLL that creates a high GCLK frequency and lowers EMI, supports dynamic frame rate modification up to 240 frames per second, is appropriate for slow-motion and multi-camera photography, and enhances the low-gray refresh rate. An improved version of MBI5754 is MBI5756. Vertical stripes, blocks, and other visual effects are enhanced by MBI5756.
Third Demo: MBI5780
A popular cathode driver integrated circuit (IC) for ultra-fine pitch screens (0.4mm–1.2mm) is the MBI5780. Currently, the accuracy is within 1% control. It has a scan-sharing design with 20 MOSFET parts and 90 scans built in. The MBI5780 can support mini-/micro-LED screens thanks to these three characteristics. Dead Pixel Isolation II is another feature of the MBI5780 that helps avoid visual difficulties with LEDs, such as caterpillar problems from short LEDs and cross effects from malfunctioning LEDs. For in-car displays, MBI5780, a contender for AEC-Q100 automotive reliability certification, is perfect. In addition to satisfying the current high demand and size growth trend of in-car displays, MBI5780 has the benefit of displaying crisp text or picture details in both bright and dim ambient light.
Common cathode LED screens preserve visual quality while using less energy. The most obvious and important benefits it offers business owners are lower investment and operating costs, which include: 1) lowering the LED display's power loss; 2) lowering the display's heat and power consumption to prevent color shift and component aging, thus increasing the display's usable life.
Additionally, common cathode LED displays may better fulfill the increasingly strict criteria of international energy conservation and carbon emission reduction legislation while also adhering to the trend of environmental preservation.
Following the pandemic, the LED display sector is evolving into a new, distinct business model. Focusing on LED display driver ICs, Macroblock is committed to quality innovation and excellence and anticipates that we will push LED displays to new heights.
