Virtual pixel technology is an innovative method for digital displays that improves resolution without the need for additional physical pixels. In the past, enhancing the resolution of LED displays necessitated the inclusion of more physical pixels, resulting in higher production costs and increased power usage. However, virtual pixel technology bypasses this issue by employing a complex arrangement of LEDs to emulate a greater pixel density.

Virtual Pixel Technology, also called dynamic pixel technology, is a technique that uses software algorithms to control the LED units in a display, so that each unit can contribute to the image of multiple pixels, thus increasing the resolution of the display by up to four times. It is different from the real pixel, where each unit corresponds to one pixel.

For example, a conference all-in-one machine that uses Virtual Pixel Technology can achieve a near 4K resolution with the same number of LED units as a 2K resolution machine. This improves the display quality and uniformity, while reducing the cost. It is a good choice for most users who want a high-definition display.

The Key of virtual pixel technology lies in its capacity to merge the color and brightness of nearby pixels to form a virtual pixel that looks smaller than it really is. Take a standard LED video wall with a 4mm pixel pitch for example. Virtual pixel technology can blend these pixels to mimic a smaller pitch, like 2mm. This effect is created by algorithms in the LED video wall's processing system that calculate the best values for each pixel, enabling it to reach a much higher resolution than what the physical pixels alone would indicate.

A patented RGBG (Red, Green, Blue, Green) setup is crucial for these displays. By skillfully mixing these colors and adjusting the pixel layout, virtual pixel technology generates bright and crisp images. This technology offers a significant edge in the digital display industry by delivering excellent image quality without the extra costs and energy use linked to larger pixel counts.

Real Pixels

As is well known, each physical pixel is composed of R,G,B diode, while in the figure below, each B diode shared by 4 pixels.This is the underlying logic of virtual pixels.

Benefit

Energy Efficiency: Virtual pixel technology is very energy-saving, using up to 50% less electricity than traditional displays. This greatly cuts down on operating expenses, making it a wise option for extended use.

Lower Operating Costs: Because it uses less energy, businesses can save significantly on their electric bills. Virtual pixel technology provides a budget-friendly option without sacrificing quality.

Durability and Long Life: These displays are made with top-notch components to ensure they are sturdy and reliable. This means less frequent maintenance and fewer replacements, offering a lasting solution.

Impressive Visual Effects: Virtual pixel technology produces stunning visuals with rich colors and clear images. This guarantees that content is always presented in its finest form, leaving a lasting impact on audiences.

Disadvantage

Virtual/Dynamic pixel technology is not a perfect solution for Micro LED display products.

• The fundamental characteristic of pixel sharing in virtual pixel technology may result in reduced display quality as the degree of virtual enhancement escalates. Insights from existing display applications reveal that, when viewed at closer distances, the visuals might exhibit a grainy texture, and static text is especially prone to displaying jagged edges. This has led to some doubts in the market, with critics arguing that virtual pixel products could potentially deceive consumers. Such sentiments contribute to a lack of enthusiasm and support for the technology.

• It does not use real physical pixels, so it may not work well in some situations. It also makes the chipset work harder and faster, which may cause it to wear out sooner and decrease the life span.
