Scanning Line and Bright/Dark Lines of LED screen
Nov 20, 2024 Scanning Line and Bright/Dark Lines of LED screen
Scanning Line The Application of Time-division Scanning for LED screen If you were to use a traditional static scanning screen design, one square meter P16 LED display would need 768 LED driver ICs. But for a P4 LED display of the same size, you'd need a whopping 12,288 LED driver ICs!(How to calculate?) It's pretty much impossible to fit that many Semiconductor Components onto the same circuit board area. That's why we use something called time-division scanning, especially for high-density, small pixel pitch LED screen. Take a look at Figure below: it shows how this works. The LEDs light up one row at a time, starting from row 1 to row n. When it's time to light up row 1, transistor Q1 turns on, and the LED driver chip activates the LED based on the grayscale value. Meanwhile, transistors Q2 to Qn are turned off. Time-division Scanning Diagram The principle of time-division scanning in LED displays is similar to that of a cathode-ray tube (CRT). When we take a photo or record video of an LED display with a shutter speed higher than the refresh rate of the LED display, black lines appear on the resulting image, as shown in below Figure . These are referred to as Scanning Lines. LED screen shows Scanning Lines due to low Refresh Rate Below Figure is a 4-scan design as an example, it takes time "A" to complete the scanning of 4 rows. If we take a photo of this display with a shutter speed faster than time "A", we call it time "B", only rows 1 to 3 will be displayed, so a black line will appear every 4 rows on the screen. However, if we use a slower shutter speed than time "A", Let's say time "C", the LED screen will be able to complete the display of rows 1 to 4, and we will get a complete image. We call the refresh rate of this display 1/A Hz. Timing Diagram of an LED Scanning Screen Bright/Dark Lines 10 Times Refresh Rate As LED screens have become popular for conference backdrops, photographers often face issues. For instance, when capturing someone in front of an LED screen, the bright background can cause the person to appear too dark in photos. To counteract this, extra lighting is used on the subject, brightening the overall scene. However, when taking a picture, the camera adjusts by narrowing the aperture and shortening the shutter speed(S ≒ 200). Unfortunately, this leads to another problem: bright and dark lines appearing on the LED screen in the background, as seen in Figure below. Due to the excessive brightness of the LED screen, the photo of main character appears too dark. Figure: Bright Line and dark line in LED screen Why does the bright/dark line appear instead of solving the scanning line ? It will be explained with the following simulation schematic. A. Shooting a 1/16 scan LED screen with Refresh Rate of 960Hz by using 1/200 shutter speed: If LED screen "A" is designed for 1/16 scan with a refresh rate of 960Hz, when taking a photo of this LED screen with shutter speed of 1/200, it will get a similar result to Figure above↑: ...

What is Virtual Pixel Technology?
Nov 16, 2024 What is Virtual Pixel Technology?
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. Virtual Pixels 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....

Color Gamut
Nov 15, 2024 Color Gamut
Definition of Color Gamut Color gamut refers to the range of all colors that a device (such as a monitor, printer, etc.) can reproduce. It reflects the device's capability in color representation, and different devices have varying color gamut ranges due to differences in technology and materials. Understanding color gamut is crucial for ensuring the accuracy of colors in images and videos, especially in fields like design, photography, and printing. In the real world, the colors of the visible spectrum in nature form the largest color gamut space, which includes all the colors that the human eye can see. To intuitively express the concept of color gamut, the CIE (International Commission on Illumination) has established a method for describing color gamut: the CIE-xy chromaticity diagram. Representation of Color Gamut CIE Chromaticity Diagram The CIE (International Commission on Illumination) has developed the CIE-xy chromaticity diagram to visually represent color gamut. In this coordinate system, the range of colors that various display devices can represent is shown as a triangular area formed by connecting three points representing RGB (Red, Green, Blue). The size and shape of this area reflect the types of colors that the device can display.The larger the area, the greater the color gamut range of the device. Color Gamut Standards sRGB: The most widely used standard, suitable for most computer and web applications, covering approximately 72% of the NTSC color gamut.The sRGB color gamut was born in 1996 and has been the most commonly used standard since the CRT(Cathode Ray Tube) era until now. Almost all monitors support sRGB nowadays, and it can easily handle web browsing, graphic work, daily office tasks, and more. Therefore, achieving 100% sRGB color gamut coverage is something that many better monitors can do now. However, the sRGB color space is only about one-third of the CIE 1931 XYZ color space, and sRGB has insufficient coverage for the green part of the color gamut. So, if an image originally has very rich greens (such as a picture of green leaves), it may lack expressiveness when viewed under sRGB. More importantly, sRGB is only suitable for self-luminous display screens to display "virtual" images and cannot be used on "physical" printed materials that rely on reflected light for color display. Therefore, to standardize the colors of printed materials, the CMYK color standard came into being. Adobe RGB: Launched by Adobe, it can express a broader range of greens and cyans, making it suitable for professional photography and design.The Adobe RGB color gamut was primarily developed to address the issue that the sRGB color gamut cannot cover the CMYK color gamut used in printing systems. Its main improvement is in the display of cyan-green tones, covering approximately 50% of the CIE 1931 XYZ color space. We can see their relationship in the color gamut diagram. Adobe RGB is a considerably large color gamut, and some high-end profes...
